We can't touch the stars, fly through distant galaxies or even land on planets outside our Solar System.
So, the only way we can study most of the Universe and everything in it, is through light.
The light we can see and the light we can't.
That's why telescopes are so important for astronomers:
they are machines for collecting light – all kinds of it.
They are just like very powerful artificial eyes to look at the sky.
The bigger the telescope, the better it can see. Why?
Because bigger eyes – like owl's eyes – have a bigger surface, so more light reaches them,
allowing the distinction of fainter differences in color and a sharper vision.
Smaller eyes – like spider eyes – have less chance of capturing light,
so they have more problems in seeing details, and everything is a little blurry.
With telescopes, it's the same.
If light was rain, and telescopes buckets to collect it,
it's easy to think that the bigger the bucket the more rain it would be able to gather.
Building very big telescopes, though, is not only expensive
but also difficult and, sometimes, even impossible.
So, what if instead of trying to build a gigantic bucket, you joined a lot of smaller ones together?
Well, great idea!
That way you would be collecting the same amount of rain,
getting the same information, but in a much easier way.
Even better: what if, instead of trying to collect all the rain, you just collected some of it,
with buckets spread in key places, so that you have enough to guess the characteristics of the rain falling?
Well, that would be much faster and cheaper!
That was precisely what astronomers thought a few years ago:
by using several different small telescopes as one, they could see extremely fine details of the Universe,
just like if they were using a single telescope several kilometers across!
They called this technique 'interferometry'.
ALMA works exactly this way, it can make 66 antennas work together as one very, very big telescope.
Making it one of the sharpest eyes to ever scan the sky.
With the sharpest eyes of all, ALMA can study very faint light in the Universe
and capture images astronomers can't even begin to imagine.

Joni's Corner: Glimpses of Glory - Duration: 1:50.
Hi, I'm Joni Eareckson Tada.
One day, as our airplane began its approach to Memphis, I remember leaning against the window
and as the sun was setting I saw a cemetery down below
now the sun rays were angled in just such a way that, as the plane descended,
I saw sunlight exploding off all the tops of hundreds of brass grave markers in kind a quick-fire succession
of sparkling light — bam! bam! bam!
The graves all flashed and dazzled as though someone were throwing firecrackers all over the cemetery.
And then, in a blink of an eye, we landed and it was all over.
Wow
That day, the Lord opened my eyes, the eyes of my heart
to gain a glimpse of glory,
A hint of First Corinthians where it says that one day, "we will all be changed—in a flash—
in a instant, the twinkling of an eye,
at the last trumpet, for the trumpet will sound,
and the dead will be raised imperishable, and we, we will be changed."
Oh friend, that is what's going to happen on the other side of your tombstone,
so ask God to open the eyes of your heart…
the Lord has sprinkled scores, hundreds of hints and whispers of his glory
absolutely everywhere.
Even in a Memphis graveyard, right next to an airport.

Strawberry Organic Fertilization and Irrigation - VLOG - Duration: 5:03.
Hello everyone. welcome to one more Vlog.
Today I'm going to get some doubts about the strawberry planting
The people have written to us. they've had doubts as to how to fertilize
then every 15 days we put a little humus
which is the product of our composter, he goes with some worms
and we put some
How much is this little ?? I do not measure right!
I put a thin layer You can see that ?
a thin layer is sufficient
And he goes with some earthworm.
This is the product of the composter. I have already shown here in the channel as it is to sift
and remove this organic matter from this way
so if you have any questions about how make the compound
just click on the "Card" and watch the video
the earth always goes down a little
and I complete more or less every 15 days
so I'm replenishing the nutrients
we had a problem with our which was as follows
you can see that so little and small
This is because it was very hot around here. more than usual
so we did two things to make it easier
Now they are going back to normal look this one from here like it is lush!
Here are some beautiful ones! Here's a set here!
This set is at the time of harvesting. including
Now you can eat
But now I do not want to. now I want to show
First we put this sombrite 50%
even so the sun was very strong! we decided to do a water installation only for the strawberries
I took advantage of faucet
And I used this same level hose. a reducer
and several drippers one on each column - each pet bottle tower
this router is very cheap in the market
and here you regulate both the water outlet
You can be strong here in the faucet to stay dripping only
leave very weak. Marcia openend now just to show you
and he also has regulation of it has some who have others
That's enough! no waste of water
This dripper as I said has a regulation
is 0 to 40 liters per hour but you will control manually
Look how dripping it is.
it has several models and it has improved very good! I was very dry and then
We put this on system has improved a lot
because we were not able to watering all the time
it's very very hot! It's a little better today because it rained yesterday
It's already dripping on this one!
It's already in the last towers.
the drip is already in the last bottles and enough is enough
You can turn it off.
strawberry is very fond of water but the must be permeable and the water must drain easily.
Do the closing:this is it for those who were waiting to see our little strawberries
Look at this one from here!
huge!
If you have any further questions can write here. as far as
We can respond And if you're new here and not yet
plant strawberries. We have video teaching how to
planting, how to replant and how to the vertical garden
We have video teaching how to prepare compost,
to have fertilizer, good soil to feed the strawberries
I hope you enjoyed! leave your like in this video and share with your friends
and we'll see you in the next video
hum ... worse: this is very good!
Worse???? !!!!!
It's really good
it's on point...

What Actors Really Use When Taking Drugs In Movies - Duration: 6:10.
A lot of things are legal in Hollywood, but cocaine and heroin?
Yeah, still not so much.
And when it comes to selling onscreen substance abuse, you can only go so far with a CGI high.
Hollywood's prop masters still have to use ingenious practical effects to make fake drugs
look like the real thing — without hurting the actors who have to put the stuff in their
lungs, up their noses, or… uh, elsewhere.
Here's what was really on the set in these movies where drugs were on the menu.
Horrible Bosses
Colin Farrell is no stranger to doing fake cocaine in front of the camera, or real cocaine
in real life, for that matter, back when he was one of Hollywood's biggest party boys.
But for Horrible Bosses, prop master Mychael Bates had the actor snorting powdered lactose
— a milk product that's so harmless, actors can inhale it without hurting themselves.
That's good news for Farrell, who was reportedly so keen on staying in character that he would
snort the fake cocaine between takes.
Pineapple Express
Despite Seth Rogen's outspoken advocacy for marijuana offscreen, the cast in the stoner
flick Pineapple Express wasn't actually smoking the real thing — which just goes to show
what a talented actor Bill Hader really is.
"Is this normal?"
Prop master Jeff Butcher purchased the movie's fake weed in bulk from International Oddities,
a company that specializes in bud without any THC, the substance that gets you high
— so that actors can smoke it, a lot, without suffering any weird after-effects.
Trainspotting
You won't be surprised to learn that Ewan McGregor and his castmates weren't shooting
real heroin in Trainspotting— in fact, no human arms were punctured in the making of
this film.
Instead, the film's prop master Gordon Fitzgerald used a real syringe filled with dyed water,
which was injected into a prosthetic arm.
According to Fitzgerald, this method had a perk: "You can draw the plunger up and down
and it looks as if the blood is mixing with the liquid."
21 Jump Street
A fictional synthetic drug is central to the plot of 21 Jump Street, which stars Channing
Tatum and Jonah Hill as cops who go undercover to stop the threat.
"Goes by the street name HFS —
"Holy F------ S---."
But while HFS is a fabrication, Tatum and Hill still needed something to put in their
mouths when it came time to film this scene where they get high to avoid blowing their
cover.
The solution?
Communion-style dissolving wafers with a hint of yellow food covering, which melt on the
tongue the same way as drugs like acid.
The Wolf of Wall Street
Needless to say, cocaine was featured heavily in The Wolf of Wall Street, which is set in
the late 1980s.
So when it came time to do lines, actors were given vitamin D powder, which is harmless
to the body when ingested in small doses.
There's just one catch: these were not small doses.
"I never had more vitamin D in my entire life.
I could have lifted a car over my f------ head"
American Gangster
Powdered heroin was central to the plot of the 2007 film American Gangster, based on
the life of career criminal Frank Lucas played, who built his empire on a fortune made by
smuggling heroin into the U.S. on military planes returning from the Vietnam war.
It's also one of the most difficult drugs to fake onscreen — which is why American
Gangster's prop master used a substance called Mannitol.
Doctors use it to treat kidney conditions and reduce brain swelling — but it's also
used by real-life drug dealers to cut heroin, making it a convincing choice.
Scarface
Not all fake cocaine is created equal— especially when the fake cocaine is actually baby laxative.
That's right: in Scarface, prop masters used powdered baby laxative to stand in for the
massive amount of cocaine that's bought, sold, and ingested by drug lord Tony Montana, played
by Al Pacino.
And while the substance didn't get anyone high, it did have certain other effects on
the human body — "So much so that no one would want to put it up their nose," according
to actor Stephen Bauer, who played Manny Rivera.
What happens when you snort too much powdered baby laxative?
Nobody's saying, but it can't be good.
"What the f*** was that?"
The Breakfast Club
Before people figured out how to make THC-free weed, oregano was the preferred stand-in for
marijuana in movies like The Breakfast Club — so that's what they're smoking in this
scene from John Hughes' classic film about a crew of misfits sentenced to high school
detention on a Saturday.
There's just one problem: back in the day, people still had some pretty weird ideas about
the physical effects of smoking up.
"Marijuana!
The burning weed with its roots in HELL!"
Thanks to the movie's prop master, the joint they're passing around looks legit — but
nothing else about this scene is especially realistic.
Half Nelson
Ryan Gosling's Oscar-nominated performance as a drug-addicted teacher in New York City
would have been wasted if Half Nelson's on-screen crack looked wack.
But prop master Jeremy Balon found an ingenious solution: an off-white coffee mug that he
"broke up into about a million little pieces, then dyed in coffee."
A piece of broken, stained porcelain would be set in front of a small ball of tobacco
that smoked when lit, lending a realistic look to Gosling's fake crack pipe.
American Beauty
For all this talk of oregano and baby laxative, it's worth noting that Hollywood still does
occasionally do its drugs the old-fashioned way — like in this scene from American Beauty,
where Kevin Spacey's Lester Burnham gets stoned in a parking lot at a real estate convention.
American Beauty director Sam Mendes said, "There may or may not have been real pot available
on that particular movie, I couldn't possibly comment" — but Kevin Spacey's giggling fit
kind of says it all.
"Honey, this is…"

Nyaaaaa ha ha, nyaaaa ha ha,
Porcelain Origin, you're cool as crack!
Are you joking my ass? look at this hot dog

DACA: Why America needs to keep the dreamers | IN 60 SECONDS - Duration: 1:22.
President Trump recently ended DACA, the program protecting nearly 700,000 undocumented immigrants
whose families brought them to the United States when they were children.
The program will be in place for the next six months, giving Congress time to provide
a legislative solution for these undocumented immigrants, commonly called Dreamers.
A study published by the Cato Institute finds that over the next decade, DACA recipients
will add hundreds of billions of dollars to the economy, and billions of dollars to the
federal Treasury.
Many hold good paying jobs.
They spend money in their communities, supporting employment themselves.
A large share are pursuing higher education, and will add significant value to the economy
when they finish their undergraduate or graduate degree.
But more is at stake than economics.
The United States gave the Dreamers security, relieving them of the fear of a knock on the
door one day, a life shattered, a forceful return to a country they do not know.
Once given, a great nation doesn't take that assurance away.
A morally serious nation doesn't extend the hand of welcome to someone one day and
then shove him out the door the next.
Congress should act to protect the Dreamers.
