The World's Most Powerful Microscope - KQED QUEST

Uploaded by KQEDondemand

---

Lawrence Berkeley National Labs just turned on a $27 million electron microscope. Its ability to make images to a resolution of half the width of a hydrogen atom makes it the most powerful microscope in the world.

Electrons sure can go inside atoms. They can interact with any electron in the atom, and some even hit the nucleus. When viewing backscattered electrons, heavier elements are brighter because their larger nuclei redirect more electrons from the beam.

Not smaller, but electrons cant go "inside" the atom and gamma rays can..

That's a technical argument and not a flame argument

Gamma rays don't really have smaller wavelengths than 300kev electrons anyway. Imaging small things is about wavelength.

Just for grins, and because this is Youtube, I'm going to argue with you ;) Doesn't actually require that much power to run an electron microscope. The lenses run at a few tens of volts, and a few amps each. Basically a bunch of lightbulbs worth of power. The really thick cable ironically carries little power too, it's mostly insulation to prevent arcing. It's 300k volts, but microamps of current. The actual wires in there are pretty thin.

You are admirable, sir.

When I grow up, I want to become a electron mircroscope ^_^

I feel my virginity is broken.

-_- shut up

Have they already tried using harmonics to stabilize these metals?

MrHavetofly

Elder races? HA

Lol a gay guy cody griffy that is looking for a microscope!

Lol

Science is awsome. i wonder if one day they could build gamma ray microscope to actually see INSIDE an atom. that would be cool wouldnt it?

That's alien talk. I KNOW YOUR SECRET.

@dgk990 you act as if you know this is a fact lmao, talkin out cho ass HOE

I'm an American, and I hate to break everyone's bubble, but according to the International Union of Pure and Applied Chemistry (Which includes the United States) we are supposed to spell it Aluminium also. You can spell it Aluminum if you want, but I prefer to agree with the Chemists that make decisions on these things.

You can't have real color when using an electron microscope since it uses electron and not light. They can manually color the images for functional reasons but the colors are chosen not observed.

Why no Colour video? Can you show us Atomic force microscopy colour video. Everyone want to see the life nano video in real colour.

Fantastic

This is so brilliant, that I feel like a bug. I wish I could see more of the component shown in the video that demonstrates the orbitals acting in a kinetic fashion under pressure! There is no doubt that there is an amazing amount of potential energy within these structures and that when we as a civilization finally un-numb our minds and figure out how to harness this potential, we will no longer think that UFO's are magic or aberrations of the atmospherics. We are at a precipice... ;-)

For once, I want to go to the comments section and not see an argument. This is a God Damned electron microscope video about the wonders of the universe. And you idiots are arguing about how to pronounce aluminum. What the F-ing F? Now, let me comment on the video like the rest of you should be doing. "Wow, I didn't know that it took so much power to make the magnetic fields to correct electron beams! I guess that is why they are so expensive. $27 million dollars. Wow!"

threadysparrow

"pronunciation"

Haha owned by deadly sniper and your comments marked as spam xD
