Atomistic Modeling : Material Science - Exploring The Atomic Composition of Alloys

[ScreamoFann]

Just to let you guys know the part where it gets to the atoms is fake. It is impossible to see an atom because atoms are much smaller then the wave lenghts necessery to even see one.

[sn1pe352]

@ScreamoFann that's a myth perpetuated by outdated science books and regurgitated by high school students

microscopy has gone a long ways, no longer limited by the wavelength we one were.

[ScreamoFann]

@sn1pe352 Please, do elaborate.

[sn1pe352]

@ScreamoFann Just go to my sn1pe352 and look in the Atomistic Modeling - Material Sciences playlist

you will see atoms for the first time, an impossibility apparently :D

[distractionxx]

interesting video and very informative

[CheetosWiitard]

240p for you own good...Trust me x)

[quangluu96]

Is the space, invisible bond?

[Crimsonyte21]

Kinda seems fake....the space between the nuclei are to small...

[gamernaveen]

What exactly is this ? Is this real imaging or just a model of a structure to the atomic extent ?

[Sadoda777]

So... those atoms are not touching each other?

[xXTheDeathReaperXx]

@Sadoda777 their not gay <===8

[Crimsonyte21]

@Sadoda777 The NUCLEI aren't touching each other,........the electron shells are though.......the nucleus of an atom takes up only 1% of the total volume.

As far as I know these types of videos are made by stitching together alot of captured images of the object as various zoom levels. At first they use optical microscopes it seems, then as you progress further in they switch to other microscopes, such as electron microscopes or similar. SO as far as I know there is no animation, only possibly computer aided blending of the frames captured by the microscopes.

[sentidocomunve]

real atoms would be stacked in hexagons

[MrFreeMinecraft]

@sn1pe352 you certainly showed that gentleman!

[siggevid]

one of the best natural highs you can get today!

[Airlight]

I've looked for years and years for these videos, I saw them as a child on a science TV show and always remembered them. I think I saw one specifically where they scanned a sparkplug. Thanks so much for posting this video!

[dutto75man]

@Airlight Is this for real? This is not animation ?

[petestrat07]

Is this real or an animation?

[IPatrickOV]

Are the dark areas between the atoms space?

[PivotSweden]

@IPatrickOV It's Dark Matter... It's the very glue of every atom...

[Arkaryon1]

@PivotSweden

no it's definitly not dark matter...

[Arkaryon1]

@IPatrickOV

no it's vacuum

the white-grey circles are elektron clouds which can be sensed -> this is the atom space where the elektrons moves

the nucleus is even many times smaller and not shown here - it's the whole atom

[ZanteF12R]

@IPatrickOV yes, because there is no matter that reflects the electrons of the miroscope

[sn1pe352]

@featheredfan I don't think you can say how many times it magnifies something, but the highest resolution you can get is about 5 nm. If you compare that to the wavelength of light, which is typically 500 nm, that's roughly 100 times the best optical microscope. I guess you could say that you are showing a 5 nm dot on a 1 mm computer screen, in which case the magnification would be 100,000 times.

[Archangeld]

@sn1pe352 Actually you can get today ~0.05nm point resolution with an abberation-corrected TEM :)

[ricktbdgc]

if this is trippy, look up quantum mechanics and it'll mess with your head

[slifergold]

beyond this, nothing more is visible for the moment.... hmm so that would mean there are always something smaller than something that smallest...

[7paco]

@slifergold yeah the atom is composed of protons, netrons and electrons. furthermore protons and neutrons are comprised of quarks and leptons. Quarks and leptons have been postulated to be comprised of even smaller preons but the standard model has slowly reduced this belief.

[sn1pe352]

2:40 and beyond is amazing
