three games three wins three clean

sheets

Liverpool start to the season combined

with the quality of their additions in

the summer transfer window has only

served to cement the idea that the Reds

are Manchester City's main threat this

season despite what rival fans often

claim about Liverpool supporters

repeatedly saying this is our year no

fan in their right mind has predicted a

tidal challenge since perhaps the summer

of 2008 when Rafa Benitez his side went

on to finish second and lost just twice

that season the other time Liverpool

finished second in recent times 2013-14

they won their opening three games but

were relatively off the pace until the

latter half of the season when eleven

wins in a row catapulted them into

contention it was a stop page time win

at Fulham in February when Reds fans

actually started to think they could

genuinely challenge the season one who

goes furthest in the Champions League

arguably if you offered Manchester City

fans the choice of winning the Premier

League or the Champions League they'd

take the European title for Liverpool it

would be vice versa city need to win the

Champions League to truly put themselves

among Europe's elite while Liverpool

need to end their domestic league trophy

drought both clubs will expect to

progress from their respective Champions

League groups although Liverpool's

certainly looks more difficult with PSG

and Napoli representing tough opposition

what happens from there on is a bit of a

lottery but what could prove key to the

destination of the Premier League title

is which of these two clubs go furthest

in Europe and put their resources into

that competition will Pep Guardiola

prioritize Champions League to luck

according to a study by an ESPN

Liverpool were the unluckiest team in

the Premier League in 27

19:18 losing 12 points due to perceived

wrong decisions that would have still

left them ten points behind City but

without European distractions they would

likely have closed that gap further the

Reds were awarded just three penalties

compared to eight the season before a

few more favorable refereeing decisions

and that left balancing out over the

season

what a Liverpool's caused another area

that luck plays a large part in his

injuries take the crew only damage to

Alex oxlade-chamberlain three weatherman

Sydney can repeat while referee

decisions and injuries are largely out

of their own hands another factor that's

completely out of Liverpool's control is

whether Manchester City can reproduce

their unprecedented form of last season

a record winning run a record points

total no major injuries city's 2017-18

season you would think is very unlikely

to be repeated already the citizens have

lost Kevin de Bruyne to an injury and

backup keeper Claudio Bravo for the

duration of 2018-19 a lot of their key

men were also involved in the latter

stages of the World Cup which could have

a long-term effect for marginal gains on

paper Liverpool and City have pretty

well matched first disc with City having

the better overall squad depth using

that depth to its maximum will play a

role in deciding the title in a bid to

narrow the gap though cloth has SATA

so-called marginal gains even going as

far as appointing a part-time throw-in

coach

he won't necessarily be working on the

technique of the throw itself but more

the receiving angles the speed of

distribution and how to minimize errors

memorably ended Manchester City's

unbeaten league run with that dramatic

4-3 win at Anfield clops I then went on

to beat Pep Guardiola's team twice more

Liverpool cannot afford to lose either

game and ideally needs to be getting a

of their 10 games against the rest of

at home to Manchester United it would be

helpful if the likes of Tottenham

What can we learn from the life of Apostle Paul? | GotQuestions.org - Duration: 9:22.

Today's question is, "What can we learn from the life of Paul?

Who was Paul?"

In this video I'll answer that question from a biblical perspective.

Afterwards, as always, I'll share some helpful resources, so stick around until the end.

There is much we can learn from the life of the apostle Paul.

Far from ordinary, Paul was given the opportunity to do extraordinary things for the kingdom

of God.

The story of Paul is a story of redemption in Jesus Christ and a testimony that no one

is beyond the saving grace of the Lord.

However, to gain the full measure of the man, we must examine his dark side and what he

symbolized before becoming "the Apostle of Grace."

Paul's early life was marked by religious zeal, brutal violence, and the relentless

persecution of the early church.

Fortunately, the later years of Paul's life show a marked difference as he lived his life

for Christ and for the advancement of His kingdom.

Paul was actually born as Saul.

He was born in Tarsus in Cilicia around AD 1–5 in a province in the southeastern corner

of modern-day Tersous, Turkey.

He was of Benjamite lineage and Hebrew ancestry.

His parents were Pharisees—fervent Jewish nationalists who adhered strictly to the Law

of Moses—who sought to protect their children from "contamination" from the Gentiles.

Anything Greek would have been despised in Saul's household, yet he could speak Greek

and passable Latin.

His household would have spoken Aramaic, a derivative of Hebrew, which was the official

language of Judea.

Saul's family were Roman citizens but viewed Jerusalem as a truly sacred and holy city.

At age thirteen Saul was sent to Palestine to learn from a rabbi named Gamaliel, under

whom Saul mastered Jewish history, the Psalms, and the works of the prophets.

His education would continue for five or six years as Saul learned such things as dissecting

Scripture.

It was during this time that he developed a question-and-answer style of teaching known

in ancient times as "diatribe."

This method of articulation helped rabbis debate the finer points of Jewish law to either

defend or prosecute those who broke the law.

Saul went on to become a lawyer, and all signs pointed to his becoming a member of the Sanhedrin,

the Jewish Supreme Court of 71 men who ruled over Jewish life and religion.

Saul was zealous for his faith, and this faith did not allow for compromise.

It is this zeal that led Saul down the path of religious extremism.

In Acts 5:27–42, Peter delivered his defense of the gospel and of Jesus in front of the

Sanhedrin, which Saul would have heard.

Gamaliel was also present and delivered a message to calm the council and prevent them

from stoning Peter.

Saul might also have been present at the trial of Stephen.

He was present for his stoning and death; he held the garments of those who did the

stoning.

After Stephen's death, "a great persecution broke out against the church in Jerusalem"

(Acts 8:1).

Saul became determined to eradicate Christians, ruthless in his pursuit as he believed he

was acting in the name of God.

Arguably, there is no one more frightening or more vicious than a religious terrorist,

especially when he believes he is doing the will of the Lord by killing innocent people.

This is exactly what Saul of Tarsus was: a religious terrorist.

Acts 8:3 states, "He began ravaging the church, entering house after house, and dragging

off men and women, he would put them in prison."

The pivotal passage in Paul's story is Acts 9:1–22, which recounts Paul's meeting

with Jesus Christ on the road from Jerusalem to Damascus, a journey of about 150 miles.

Saul was angered by what he had seen and filled with murderous rage against the Christians.

Before departing on his journey, he had asked the high priest for letters to the synagogues

in Damascus, asking for permission to bring any Christians (followers of "the Way,"

as they were known) back to Jerusalem to imprison them.

On the road Saul was caught in a bright light from heaven that caused him to fall face down

on the ground.

He heard the words, "Saul, Saul, why are you persecuting me?"

He replied, "Who are you Lord?"

Jesus answered directly and clearly, "I am Jesus, whom you are persecuting" (verses

4–5).

As an aside, this might not have been Saul's first encounter with Jesus, as some scholars

suggest that young Saul might have known of Jesus and that he might have actually witnessed

His death.

From that moment on, Saul's life was turned upside down.

The light of the Lord blinded him, and as he traveled on he had to rely on his companions.

As instructed by Jesus, Saul continued to Damascus to make contact with a man named

Ananias, who was hesitant at first to meet Saul because he knew Saul's reputation as

an evil man.

But the Lord told Ananias that Saul was a "chosen instrument" to carry His name

before the Gentiles, kings, and the children of Israel and would suffer for doing so.

Ananias followed the Lord's instructions and found Saul, on whom he laid hands, and

told him of his vision of Jesus Christ.

Through prayer, Saul received the Holy Spirit, regained his sight, and was baptized.

Saul immediately went into the synagogues and proclaimed Jesus as the Son of God.

The people were amazed and skeptical, as Saul's reputation was well known.

The Jews thought he had come to take away the Christians, but he had in fact joined

them.

Saul's boldness increased as the Jews living in Damascus were confounded by Saul's arguments

proving that Jesus was the Christ.

Saul spent time in Arabia, Damascus, Jerusalem, Syria, and his native Cilicia, and Barnabas

enlisted his help to teach those in the church in Antioch.

Interestingly, the Christians driven out of Judea by the persecution that arose after

Stephen's death founded this multiracial church.

Saul took his first of three missionary journeys in the late AD 40s.

As he spent more time in Gentile areas, Saul began to go by his Roman name Paul.

Paul wrote many of the New Testament books.

Most theologians are in agreement that he wrote Romans, 1 and 2 Corinthians, Galatians,

Philippians, 1 and 2 Thessalonians, Philemon, Ephesians, Colossians, 1 and 2 Timothy, and

Titus.

These thirteen "letters" (or epistles) make up the "Pauline Authorship" and are

the primary source of his theology.

As previously noted, the book of Acts gives us a historical look at Paul's life and

times.

The apostle Paul spent his life proclaiming the risen Christ Jesus throughout the Roman

world, often at great personal peril.

It is assumed that Paul died a martyr's death in the mid-to-late AD 60s in Rome.

So, what can we learn from the life of the apostle Paul?

First, we learn that God can save anyone.

The remarkable story of Paul repeats itself every day as sinful, broken people all over

the world are transformed by God's saving grace in Jesus Christ.

Some of these people have done despicable things to other human beings, while some just

try to live a moral life thinking that God will smile upon them on the day of judgment.

When we read the story of Paul, we are amazed that God would allow into heaven a religious

extremist who murdered innocent women and children.

Today, we might see terrorists or other criminals as unworthy of redemption because their crimes

against humanity are just too great.

The story of Paul is a story that can be told today—he isn't worthy in our eyes of a

second chance, yet God granted him mercy.

The truth is that every person matters to God, from the "good, decent," average

person to the "wicked, evil," degenerate one.

Only God can save a soul from hell.

Second, we learn from the life of Paul that anyone can be a humble, powerful witness for

Jesus Christ.

Arguably, no other human figure in the Bible demonstrated more humility while sharing the

gospel of Jesus Christ as Paul.

Acts 20:19 tells us that he "served the Lord with all humility and with tears and

with trials that happened to [him] through the plots of the Jews."

In Acts 28:31, Paul shares the good news of Jesus Christ: "Boldly and without hindrance

he preached the kingdom of God and taught about the Lord Jesus Christ."

Paul was not afraid to tell others what the Lord had done for him.

Paul spent all his days, from conversion to martyrdom, working tirelessly for the kingdom

of God.

Finally, we learn that anyone can surrender completely to God.

Paul was fully committed to God.

In Philippians 1:12–14, Paul wrote from prison, "I want you to know, brothers, that

what has happened to me has really served to advance the gospel, so that it has become

known throughout the whole imperial guard and to all the rest that my imprisonment is

for Christ.

And most of the brothers, having become confident in the Lord by my imprisonment, are much more

bold to speak the word without fear."

Despite his circumstances, Paul praised God and continually shared the good news.

Through his hardships and suffering, Paul knew the outcome of a life well lived for

Christ.

He had surrendered his life fully, trusting God for everything.

He wrote, "For to me to live is Christ, and to die is gain" (Philippians 1:21).

Can we make the same claim?

Sadhguru - If you can control these 5 elements.. - Duration: 10:06.

Tracey: And so the title of this conversation the subtitle of conversation with the mystic

Sadhguru: That's only for you.

I am not conversing with a mystic, so I am at ease.

(Laughter) Tracey: That's my job got it.

I know and I have many questions you know.

Sadhguru said, 'I have never seen someone with so many questions.'

He said, 'No answers, only questions.'

I think that the the subtext which I actually am talking about

because I liked it, is an experiential… for today, an experiential

symposium on optimal health and well-being.

And I think there is a tremendous amount for us to talk about even in that phrase.

One is the role of experience and and I will say that, you know,

my office being responsible for cultural transformation, I've become obsessed with what is culture

and the definition that I use because it guides our strategies.

is behavior.

This definition was given to me by Erma Rosenberger is behavior either collective or individual

behavior based in experience and in sentence;

meaning that if we are going to transform or shift what medical… the medical model

is today and what healthcare is today,

we can't start with just the data, if people do not have an inner experience,

not much will change.

Do you… can you say some about what do you think the role of experience is

in today and… and in healthcare Sadhguru: See, you need to understand this

largely for most human beings, experience is being kind of created and regulated

by the way they think and feel.

But what you think and what you feel need not

necessarily have anything to do with reality as such.

There is something called as a psychological reality and

there is an existential reality.

By controlling or handling the psychological reality well,

a lot of people can become healthy, a lot;

because for lot of them, that is the cause of their ailment.

And it can also fix other things to some extent.

So psychol….

like right now, Mitch was talking about, you know,

somebody prays and somebody creates a certain attitude around them of

love and care and compassion, this is all psychological structure.

You create a psychological structure with which you become open to certain dimensions

of life.

You…

It becomes a possibility to transact in a certain way

with least amount of friction and creates well-being.

But there is an existential dimension to this.

Existentially what are you made of what are… what is the world made of, if

you look at it, this is the most fundamental aspect of yoga.

This is called as Bhuta Shuddhi.

This means elemental… cleansing of the elemental nature.

The whole universe is a manifestation of five elements.

So is this body.

Out of these five, there are only four that you can really handle;

another one you just experience, it's the ambience for the other four.

So, the earth, water, fire, air, and the space.

So you only have to handle really four.

With four ingredients, so much magic and mischief is happening in the universe.

If there were four million, we would be not able to handle it.

Four, for sure we can handle, isn't it?

Four ingredients if they're functioning the way you want them,

then everything about you will be great.

Out of these four, 72% of your water

I mean …your body is actually water, so is the planet.

The same composition of the planet you have in your body;

about 12% is earth; about 6% is air;

4% is fire; the remaining is space

this is how it is looked at.

If you master these four, even if you have a bit of control over these

four, you will see miraculously you will generate

health within the system.

If you fail on this, then the next level of handling this is

nature has evolved certain things in the form of herbs and very things

many things which are healthful to us.

So we can learn to use them.

If you fail in that, then you can create a psychological structure

which will create health for you.

If you fail in that, then you go for the chemical treatment.

If you fail in that, then you go for a surgery.

(Laughs) Direct intervention of cutting something,

putting something, if nothing else you are capable of doing.

But now you are talking about a large scale thing across the populations.

We always think anything subtle cannot be done large scale.

I disagree with that, this is my opinion; because it is just that we have not done enough

work towards that and we assume that it's not possible.

To create a certain sensitivity towards something and

approach it in a subtle manner is possible, but it's only possible

if it goes into every home, every parent, every man and woman in the world or in the

country starts working towards it.

When you want such a big goal to be achieved, it's not going to happen overnight.

We must be willing to be committed for a whole generation or two,

then something will happen; something wonderful will happen.

But right now, we are in today's world, everything has

to happen by today evening; if it doesn't happen, tomorrow we dump it

and have a new project going.

So in that context, it will not happen.

In that context, it's bet… better we work towards

a plastic heart and a plastic liver and a plastic kidney where we can start replacing

them every five years and somehow function.

See, health does not mean that just the medical parameters are okay.

Health means you must feel a certain sense of wholeness.

The word health itself comes from that word 'whole.'

A certain sense of wholeness when you wake up in the morning, you are more

alive than you are when you went to bed, you feel ten years younger than the time when

you went to bed.

If you feel like that, that means you are healthy.

It is just that all the tests are showing you are normal,

that is still not normal because you have no experience of health.

So when you say experience, ultimately we have come here only to experience

life, isn't it?

So we know that experience is the most important aspect of life.

Now we are talking about the word experience in two different ways.

One is our experience of life itself, how profound and how wonderful it is or how

nasty and how unpleasant it is.

So the pleasantness that we generate in the body,

we call this as health.

Right now, that is the object of discussion.

I don't want to go further but the same pleasantness if it hits a higher pitch,

we call it pleasure.

But if your mind becomes pleasant, you would call it peacefulness.

If it becomes very pleasant, you would call it joyfulness.

If your emotions become pleasant, you would call it love or affection.

If it becomes very pleasant, you would call it compassion.

If your very life energy if you make it pleasant, we call it bliss.

If it becomes very pleasant, we call it ecstasy.

This is what a human being is seeking all the time.

He wants pleasantness inside.

Well, if your surroundings become pleasant, we call it success.

This is what every human being is looking for all the time.

There is a whole science as to how to create the inner pleasantness.

External pleasantness needs cooperation from many people.

It's not just yours.

There are other stakeholders who may want to make it nasty for you.

(Laughs) It needs many people's cooperation

but inner pleasantness is one hundred percent yours.

But why have you not strived for it?

We have not strived for it because generally we have spread this message,

'It is not possible unless everything in the universe is fixed.'

When I first came to United States, one word I was hearing everywhere is, 'stress

management.'

(Few Laugh) I could not understand this because in my

mind, we manage things which are precious to us

our family, our wealth, our business and whatever else which is valuable to us.

Why would anybody want to manage stress, is something I couldn't get for some time.

(Laughs) It is just because we have spread the idea

that stress is a part of your life.

Stress is not a part of your life, stress is not because of your job,

stress is simply because you do not know how to manage your own system.

Princess Diana: The surprising reason YOU can remember where you were when Diana died - Duration: 3:54.

 Psychologists argue this traumatic incident left such a scar on the national consciousness that it triggered a "flashbulb" memory

Princess Diana died on August 31, 1997 after her car crashed at the entrance of the Pont de l'Alma road tunnel in Paris, France

It is not uncommon for people to remember exactly where they were and what they were doing when they learnt the shocking news

This could be because it has become a "flashbulb memory", which can occur after significant incidents

 Flashbulb memories are stored in our minds "as vividly, completely and accurately as a photograph"

The American Psychological Association say flashbulb memories were first proposed back in 1977 by Harvard psychologists Roger Brown and James Kulik

They can be triggered by dramatic events, particularly those which occur in public

Cognitive psychologist William Hurst said: "Every time there's a public trauma, psychologists run out in the street and capture people's memories of what happened

 "They did it with the Challenger explosion. They did it with the death of Princess Diana – and we did it with 9/11

"What makes these events so memorable is the unusual intersection of the personal and the public, so that what becomes salient for you is actually learning about the event, in addition to the facts of it

"Last year, on the 20th anniversary of the Princess of Wales' death, the nation took to social media to share their memory of hearing the news

TV presenter Chris Tarrant was on a flight back from Canada.  The Who Wants to be a Millionaire host said: "There was a sound of crying as news spread around the plane

"Mirror columnist and then GMTV presenter Fiona Phillips said: "When I was called out of my bed in the early hours 20 years ago to deliver the news on GMTV that Diana had died, I couldn't believe what I was hearing

"I fumbled around for a black suit, hoping that somehow the news wasn't true; that I wouldn't have to wear it

I wore it. "I was still barely coming to terms with the shock, the emotion, the enormity of what had happened as I sat there and delivered it

" Tony Blair, who had been prime minister for just three months when Diana died, remembered being woken up by the police

 Mr Blair said: "I was woken by the policeman. He was standing at the foot of the bed because I hadn't heard the phone ring

"It was an extraordinary shock because I knew her, I liked her a lot."Tony Blair later addressed the nation from outside a church in his Sedgefield constituency, where he said: "I feel like everyone else in this country today - utterly devastated

"She was the people's princess and that is how she will stay, how she will remain in our hearts and in our memories forever

"It was a speech which would become famous for articulating the sense of national loss

You can see INFRARED?!? Failing safety glasses - Duration: 10:21.

Hi! This is a follow-up to my latest video

where I showed infrared leakage

from my three, cheap, green laser pointers.

Why is invisible infrared a problem?

Is it really invisible?

Won't safety glasses protect against infrared?

These were some of your questions I'll try to answer in this video.

In short: Your eyesight could be in danger.

Powerful lasers will damage your eyes.

Always use laser safety glasses.

Especially when using reflective glass in front of them

and invisible lasers as I do in this video.

In the previous video I showed how one of my infrared lasers

is very visible to the camera

while another one isn't. This made me curious.

Are they then both invisible to my eyes

without safety glasses on?

This is of course not recommended to try.

Do as I say - not as I do but under controlled

circumstances I had a short peek at

these laser dots without my safety glasses on.

The 980 nm laser is completely invisible to me

but to my surprise I saw a faint, cherry-red line

from the 808 nanometers laser.

What is going on? Do I have superhuman vision?

Or was I just scammed by an eBay seller

who sold me a weak, red laser?

Well, while it looks weak and dim to my eyes

it sure has some power to it. Here I demonstrate

how it chars paper and even melts plastic rather quickly.

But what wavelength is this then?

Visible light only goes up to

around 700 or 750 nm according to common sources

so 808 nm is considered infrared - not visible.

Luckily it's easy to measure the wavelength as

shown earlier so I did a quick test with

the infrared laser and the wavelength is...

... confirmed.

This truly is an 808 nm laser.

The seller didn't scam me.

Huh! So I've got superhuman vision.

Nice!

Uhm. Not really...

The human eye is most sensitive to 555 nanometers.

Nice number - easy to remember.

5 5 5 nm is a yellow-green color

you may recognize from high-visibility clothing.

Our eyes' high sensitivity to yellow-green

makes it very visible even at low light.

Fluorescence is also part of the brightness from these clothes

but that's in a different video.

If the sensitivity around 808 nm is 0%

I shouldn't be able to see

a dim, red dot from the laser at all.

In reality our eyes' sensitivity at 810 nm is

0.

0

0

0.00018%.

So it isn't 0!

At an extreme brightness like a 200 mW laser

we can actually see the 808 nm color.

At a more everyday brightness it's not visible

so we usually call it infrared or near-infrared.

Our eyes are not digital

and will not suddenly shut off

from one wavelength to another between red and infrared.

It is a gradual decline

in sensitivity over a range in the near-infrared wavelengths.

The 980 nm laser is completely invisible to me

so the possible 1064 nm leakage

from a green laser will also be impossible for me to see.

I would like to show you

how the 808 nm laser looks to me

but my cameras record the dot

as a violet or white light - not a deep red as I see it.

So I could mimic it with a visual effect in my video editor

but that would be boring.

Let me show it with an actual laser instead.

I have butchered this keychain red laser

and will underpower it with only 2.4 V.

This way I should get a dim red dot.

Yep, that's not far from the experience with the infrared laser.

It just should be more like a line instead.

Yes! That's it.

This is very close to how the dot from the 808 nm laser looks to me.

Just for comparison here's

how a 660 nm laser of the same 200 milliwatts power looks like.

This is the big issue with infrared coming from a green laser.

Either you don't see it at all

or it looks very dim - but it can be more

than powerful enough to burn your retinas

without you even blinking when it hits your eye.

Not that the blink reflex is fast enough to save your eyes

with powerful lasers anyway...

Don't let your retina look like this after playing

with a poorly filtered, high-powered green laser.

But with a green laser

isn't there also a bright green beam following the infrared?

So what's the problem?

Just avoid the green beam and the infrared doesn't matter.

Unfortunately, it is dangerous to think like that.

Using a green laser without an infrared filter

you can end up having infrared by itself.

First off, the infrared beam is spreading more

than the collimated green laser beam.

The lenses inside the laser can't focus

the different wavelengths to the same point.

Notice how wide the infrared spread

is on the IR-card at a short distance.

Much wider than the thin, green beam.

Another case is if you drop the laser

and misalign the crystals

converting the infrared light from the pump diode.

Then your laser will emit little to no green

but a lot of unconverted infrared.

Green lasers also tend to be inefficient in cold weather

so if you use an unfiltered green laser

to point out a star on a freezing clear night

you may experience that the green is dim due to cold conversion crystals.

But the infrared pump diode is still working fine

and pumping out a lot of infrared.

Risky without an infrared filter...

Another risk is windows with an infrared reflecting film or coating.

These are common in buildings with a lot of glass surface - or on cars -

to keep the infrared heat coming from the sun out.

It's not a good idea to shine lasers

at reflective surfaces but if you shine

a green laser on such a window

the green laser light can go through

while any infrared leakage can be reflected back.

Maybe into your eye.

Don't assume that the green and infrared beams are always in the same spot.

All right... but my safety glasses will protect me against stray infrared!

Are you sure?

Let's test my four laser safety glasses.

It's a bad idea to point lasers directly on safety glasses.

The beam can burn through and render the glasses useless.

I'm using my least powerful green laser for this

and will keep it constantly moving

so it shouldn't destroy the glasses.

First up are a pair from Wicked Lasers.

Not expensive but meant for low-powered, green laser pointers.

Let's see if they block infrared too.

Nnnnnnno - not at all. Lots of infrared detected on the card.

It's the same with their more sporty looking glasses.

To be fair they are not advertised to protect against infrared.

Only some visible wavelengths and only OD2+

which is suitable for a power up to around 100 mW.

My blue glasses are meant for red lasers

so don't make much sense with a green laser pointer.

I just want to see if they protect against infrared.

Nope...

Now these are my best pair.

They have lots of markings showing

what they protect against and how much.

They should block both green and infrared.

Let's see if it is true.

Ah yes! This is what my eyes want to see.

Nothing detectable goes through.

These will protect my eyes in the case of a mishap

with all my green lasers - infrared filtered or not.

Nice to know and just confirms for me

and hopefully for you too

that expensive safety glasses are worth it.

Guard your priceless vision

when using high-powered lasers and be aware of infrared radiation.

Please!

Hope you liked this closer look on a safety issue that may not be so obvious.

Part of it is literally invisible.

I feel good learning more about infrared and how to deal with it

from making this and the previous video.

If you feel the same and want to learn more about science without buying

expensive stuff and dealing with the risks

I have a nice tip for you.

Brilliant.org is a problem-solving website

where you can learn to think like a scientist

by performing your own thought-experiments.

They have just launched a new course called Science Essentials

where you can learn more about for example the scientific process

and measurements in an easy-to-understand way.

I'm a fan of science and always like learning more about it.

If you want to learn more too and believe in active learning

I highly recommend you go to Brilliant.org/Brainiac75

and sign up for free.

As a bonus the first 275 people using the link

will even get 20% off the annual premium subscription.

Then you can do more crazy stuff without any safety warnings from me.

Before I tease you with the topic for the next video

I have a premiere for my channel.

For the first time ever I have patrons supporting my channel.

Are you ready to see the names of some awesome and generous people?

Roll the credits!

Thank you so much to all of you.

Thanks for having my back.

You're giving me some much-needed confidence to carry on making videos.

Alright, time to end this video with a little teaser for my next video.

It's time for part 6 of my series 'Exotic Elements vs. Magnet'.

Yes, I have finally found and been able to afford five new elements.

Can't wait to test them near a magnet

and show you the beautiful and beasty samples.

Remember to click like if you lick...

*embarrassed laugh*

...LIKED the video enough to watch this far.

And maybe even subscribe for the next video.

Thanks for watching! Bye for now.

Can the Police Commit Crimes While Undercover? - Duration: 14:35.

The use of undercover or covert law enforcement is common throughout much of the world and,

for the most part, men and women tasked with going undercover are expected to, and do,

follow the law.

However, beyond the occasional bad officer doing things they aren't supposed to, exceptions

can and will be made on a case by case basis, making undercover police some of the few people

who are paradoxically legally allowed to commit certain crimes while they try to catch other

people committing crimes.

And before we continue, we should probably also just quickly state that the common internet

rumor that undercover officers must admit to being such if asked is completely false.

They can happily lie to your face if they want, which is pretty essential to the whole

job of being an undercover agent.

In any event, as alluded to, before undercover police officers and covert agents in many

countries of the world commit any kind of crime, they are generally required to get

prior approval from someone higher up the chain of command.

However, as with most things in life, there are of course exceptions to this and if an

individual officer feels that they have to commit a given crime to maintain their cover,

they're tentatively free to do so at their own discretion, but with full knowledge that

they'll almost certainly be required to justify this decision and there's no guarantee

that their superiors will agree with them.

This potentially opens up the officer to criminal charges themselves.

That said, one of the ways some undercover operations have historically gotten around

this in a very controversial way is to simply keep everything under wraps and potentially

even lie on their reports, which is where the controversy occasionally pops up when

this is discovered.

For example, it was noted by the Justice Department's Inspector General in 2005 that the FBI regularly

broke the rules and disregarded guidelines over the course of their undercover investigations,

generally with no consequences to the agents involved.

As a worse example, we have the relatively recent case where a three year investigation

ended up all being wasted time and effort because it was revealed that the undercover

officer, according to Judge Cam Ferenbach, "deployed techniques that generated a wholly

new crime for the sake of pressing criminal charges against [Jeremy] Halgat."

The officer appears to have taken this route after repeatedly trying to get Halgat to commit

a crime, but with Halgat refusing.

Judge Stephen Reinhardt would also ring in about the ATF's conduct in this and other

similar operations around this time, stating, "In this era of mass incarceration, in which

we already lock up more of our population than any other nation on Earth, it is especially

curious that the government feels compelled to invent fake crimes and imprison people

for long periods of time for agreeing to participate in them — people who but for the government's

scheme might not have ever entered the world of major felonies.

… When the government decides to troll though poverty-stricken neighborhoods, ordering its

agents to seek out people who look 'bad' and test them at random for willingness to

break the law in order to obtain large sums of money, its conduct is unacceptable."

Unsurprisingly, as with any industry, there are always bad eggs to be found.

But for those better officers who actually stick to the rules, we have, for example,

official FBI guidelines about undercover operations stating that "Except when authorized pursuant

to these Guidelines, no undercover employee shall engage in any activity that would constitute

a violation of Federal, state, or local law if engaged in by a private person acting without

authorization."

In fact, if you read the whole document, undercover FBI agents can't even jaywalk or litter

without express permission from a superior or handler.

Of course, an undercover agent posing as a hardened criminal would look mighty suspicious

if they dutifully obeyed every law.

And any criminal operation could quickly weed out any such undercover agents simply by asking

them to break a law and seeing what happened next.

Again, to get around this sort of issue, most officers are given prior approval to commit

minor crimes that might come into play in a given under cover scenario prior to deployment;

the key here generally comes down to whether or not committing the given minor crime will

blow the officer's cover or not or is integral to the operation, such as selling or purchasing

drugs.

On that note, undercover agents can commit more major crimes, including even bribing

politicians, so long as prior approval to do so is obtained.

In the case where approval to commit a crime or perform a given illegal activity isn't

obtained, undercover agents are often given broad authorization to commit crimes that

were "unforseen" if they believe doing so to be "necessary and appropriate" to

their continuing investigation or in some cases if necessary for their own personal

safety.

In such a case, the guidelines note that permission to commit the crime can be "retroactively

authorized if appropriate".

All this said, these officers are usually prohibited from engaging "in any act of

violence" or from attempting to instigate a crime themselves, but, again, there are

exceptions.

For example, they can engage in an act of violence if doing so in either self defence

or to protect the life or wellbeing of the innocent.

It's also noted that generally permission is required to break the law not just for

more obvious reasons, but to ensure that the officers are appropriately considering the

issue of entrapment which was somewhat alluded to in the aforementioned ATF case.

But for anyone unfamiliar with the term, entrapment is described thusly in the FBI guidelines:

Entrapment occurs when the Government implants in the mind of a person who is not otherwise

disposed to commit the offense the disposition to commit the offense and then induces the

commission of that offense in order to prosecute.

To avoid this and other such issues, any plan suggested by an undercover agent must be checked

and authorized by the upper echelons of FBI command who need to ensure, amongst other

things, that planning the crime is necessary to reveal evidence of other, worse crimes

or the like.

So, for example, an undercover agent could propose stealing some cars to take part in

an illegal street race if doing so would allow them to earn the trust of an individual they

suspect has been hijacking trucks containing millions of dollars worth of cargo…

Officers are also often encouraged to develop romantic relationships as a great tool to

integrate oneself in a given organization, though as we'll get into in a minute, this

one has caused major issues over in the UK in recent years.

But just as a general rule of thumb to keep in mind- the more serious the crime being

investigated, the more leeway an officer or agent is likely to be given to commit crimes

in their pursuit of arresting other people committing crimes.

As an aside, we should probably mention that many of these protections are also granted

to FBI and police informants who can be granted blanket immunity for minor or agreed upon

crimes they may commit while acting as an informant in return for their testimony.

This, too, is not without controversy owing to the secrecy departments usually maintain

with this sort of thing and the fact that when deep investigations are sometimes done,

it occasionally reveals things happening outside of the rules, including in rare cases the

embarrassment of informants getting away with a vast array of crimes for their own benefit

simply because they're on good terms with the authorities and are providing valuable

information.

On this note, in a report from 2011, it was noted that the FBI allowed informants to break

the law almost 6,000 times in that year alone.

Being forced to report these tallies every year began after it was revealed that the

FBI was allowing famed mobster and many time murderer James Bulger to operate a vast crime

ring in exchange for him revealing information about other mobster activities.

Another reason these informants sometimes cause controversy is when they more or less

manufacture crimes to keep themselves useful and on the payroll.

As Former DEA agent Michael Levine notes, "You want to catch bad guys, people who

are committing crime, people who have committed murder.

You don't want your informant to go out and talk someone into it.

You can do that all day long and fill jails from the Bronx to Bogota, Colombia.

It's the easiest thing in the world to do, but that's not law enforcement."

Over in the UK the rules are somewhat similar, though in more recent years the ability of

undercover police to commit crimes has been drastically limited after a series of scandals

involving undercover police officers.

These scandals primarily revolved around a little-known covert unit of Scotland Yard

known as the Special Demonstrations Squad.

In a nutshell, covert officers working with the SDS were tasked with infiltrating protest

groups and the like.

The Guardian would eventually reveal that many officers were doing things like sleeping

with those they were investigating and in some cases, marrying and fathering children

with their targets before, sometimes after years of a relationship, disappearing forever

when the investigation was over, including potentially abandoning not just their unsuspecting

spouse or partner (and, indeed, in some cases the officers already had spouses besides in

their real lives), but the children they had with these women.

Just as controversially, the officers had a common practice of selecting a deceased

child born around the same time as themselves and with a similar name, and then assuming

that identity without permission from the surviving parents and relatives.

Not only this, but they would go further and research the various family member backgrounds

and sometimes even visit the homes and areas they were supposedly raised in to help their

cover.

Not just insensitive, this also in some cases placed these surviving relatives in potential

direct danger given the supposed association between these people and the undercover officers'

assumed identity, especially when said officers then up and disappeared when the investigation

was over.

In addition, other officers were found to have taken drugs while undercover (a big no

no due to the risk of becoming addicted, potential to blow their cover inadvertently while under

the effects of the drugs, and the fact that narcotic use can weaken an officer's testimony

in court, potentially hurting the whole point of the operation).

In some cases they were also found to have taken part in various acts of violence or

other such more serious crimes, including in one case a major arson incident in a public

building that risked civilian lives.

In perhaps the most famous case, involving a highly decorated officer by the name of

Bob Lambert, he was investigating an animal rights group and so hitched up with an animal

rights activist who would eventually become the mother of his child.

Again, this practice of forming romantic relationships for undercover officers had formerly been

considered (and still is in some agencies) an invaluable tool to quickly integrate an

agent within some organization.

As for Bob's lady, however, she only discovered her whole relationship with him had been a

sham after seeing his picture in the paper some two decades after he disappeared from

her life, leaving her to raise their child alone and in poverty.

She stated of this, "Bob was there by my side through the 14 hours of labour in the

autumn of 1985 when our son was born.

He seemed to be besotted with the baby.

I didn't realise then that he was already married with two other children…"

She went on, "There can be no excuses for what he did: for the betrayal, the manipulation

and the lies … I loved him so much, but now have to accept that he never existed….

I don't understand what I am supposed to have done that I was chosen by the state to

be treated like this.

I was no threat to national security and what was my child – collateral damage?"

During the investigation it was also noted that undercover officers regularly withheld

information about their activities from prosecutors in instances where it would weaken the case

they were building or otherwise get the undercover officers in trouble.

They also occasionally were found to have allowed false evidence to be used against

people.

In response to the controversy, the British government introduced sweeping legislation

severely limiting the ability of undercover officers to commit crimes and form relationships

with those they were investigating.

A Cliff notes version of the 80 page list of instructions handed to officers is that

sexual contact of any kind, as well as the taking of any illegal drug during an investigation,

was now technically banned.

However, much in the same way FBI agents and the like can commit crimes at their own discretion

if they feel it necessary to their investigation, the new guidelines noted that undercover officers

could engage in sexual activity to mitigate an immediate threat, but only to the smallest

degree needed in a given case.

While seeming absurd on the surface, this is actually an important clause given that

without it, discovering an undercover officer would be as easy as simply mandating they

have sex with someone.

In addition, while undercover officers can't otherwise have sex with a person they're

investigating or in connection to an investigation, official guidelines do permit them to engage

in "communications of a sexual nature" if they feel it is necessary to achieving

their objective.

So sexting is still considered OK apparently…

Likewise, the guidelines note that while drugs are absolutely not "authorised as a tactic

of a deployment", officers can take drugs if there is an immediate, present threat to

their own or another's safety.

As with the guidelines about having sex, in such a scenario, the officer is only permitted

to take enough drugs to "mitigate the threat" and no more.

So to sum up, undercover agents in most regions of the world can absolutely commit crimes

while undercover, though the extent and severity of the crimes they are allowed to commit varies

depending on who or what they are investigating.

However, in general, to cover their own backsides and ensure the case they are building against

someone is as strong as possible, a good officer will avoid committing crimes

whenever possible.

Does being beautiful mean dying sooner? In nature, it can. | Richard Prum - Duration: 4:03.

One of the most extraordinary examples of beauty happening in the natural world is the

courtship display song of the Club-winged Manakin.

The club-winged manakin is a South American bird that sings with its wings.

The female club-winged does all the nesting and builds the nest and lays the eggs and

takes care of them all on her own, but she chooses among available mates based on the

songs they sing.

But they sing with their wing feathers in a very special way: by shaking their wing

feathers rapidly over their back they create an "electronic" sound that sounds like

"Bip!

Bip!

WAAANG" that rings out of the forest, and yet this is actually produced by the wing

feathers rubbing together.

This is interesting because it shows that beauty can be innovative.

Birds have been singing songs, vocal songs with their syrinx for something like 80 million

years, but this bird has essentially abandoned vocal songs to create music in a whole new

way with its wing feathers.

Studies have shown that as we look inside the body of the male club-winged manakin the

wing bones have been greatly altered in order to make this sound.

What this means is that beauty is not only skin deep: in order to make these beautiful

attractive sounds the wing bones have become elaborated and even solid like ivory.

This is a big deal because all birds have hollow wing bones: even Velociraptor and T

Rex have hollow arm bones, so this is a design that goes back prior to the origin of birds

and prior to the origin of flight!

But flying birds all maintained hollow wing bones, but somehow or other the male club-winged

manakin has abandoned them in order to produce his wing song.

This is interesting because his wing bones are actually made worse at flying by the compromise

to be beautiful, in order to make the songs that females love.

Then the male has been dragged off that optimal design toward a new design, which functions

less well at flying; in other words the male has been made less capable at flight by female

choice.

That kind of investment or cost COULD be rationalized as another kind of "honesty," a kind of

handicap that indicates how good he is, that he can waste energy to make the wing bones.

I wanted to test that idea by exploring what's going on in female club-winged manakins.

It turns out that female club wings have the same elaborate, thickened, or wider wing bones

as the males, yet they will never sing a wing song.

How does that work?

Well, it turns out that the wing bones develop in the embryo in the egg before the embryo

becomes either male or female.

And as a result when the female selects on the males that she likes with the song that

she likes, her female offspring will also inherit bizarre wing bones, and yet they won't

be made better by them.

They will never profit from them.

So in this case of the club-winged manakin, both males and females are made worse off

as a result of mate choice.

I call this the "evolution of decadence".

It's an example of how mate choice or evolution by mate choice can work in an entirely opposite

or opposing direction to natural selection.

I think that's a case where we are driven to accept the idea that beauty happens.
