The Magnified Tip Of A Tungsten Needle [Pic]

Submitted by: patchgrabber 4 years ago in Science

A Tungsten Needle is the sharpest object ever made by man. The circles are individual atoms.

real atoms dont look as pretty as the pictures in your elementary school textbook guys

@Andicicle: that`s mistakes made during measuring, it says so in the AIP source of the picture. Kinda like a blur when your hand isn`t stable enough while taking a picture.

Also, if its atoms, why is there several red blobs? That matter is apparently magical in that it isn`t composed of atoms.

This place is a regular brainazium, if such a thing ever existed.

@WesleyV78: it`s not a "photography", if that`s what you`re referring to, but I can tell you with absolute certainty that those pictures are of atoms and are not done with photons: they are done collecting information about the variation of the fields as the probe approaches a sample. The idea being that if the calculated interaction variable between the probe and the sample matches the influence measured externally, then you can deduce the distance between the probe (which you know) and the sample with some post processing, the specifics of which I personally haven`t worked with but it doesn`t seem implausible or wrong.

So yeah, no photonic-graphs are possible, but pictures are.

Maybe it is a real picture. However, the description is wrong. Atoms cannot be photograghed. It is a simple analysis of photons that prevent forever the visual rendering of atoms. Also, picture 2 out of 10. Whatever it is a picture of is uninteresting and mislabeled.

It`s not fake, but it`s also not the sharpest thing ever made. The cantilevers used in atomic force microscopy are much "sharper"

@SmagBoy1, well given that Tungsten is a single element, then yeah those are atoms.

The picture is of course false colour.

I am a physicist, though not exactly an "atomic scientist", but I can tell you mapping individual atoms has been possible for some time now, so there`s nothing particularly incredible about the fact that we took a picture of the atoms of something.

I accept that American Institute of Physics picture says it`s an atom, but I`m going to say that`s a mistake, and that they meant "molecule." I`m not certain of course. But, here`s the article that Runemang was talking about: here. Maybe an atomic scientist can help us out?

American Institute of Physics wouldn`t lie, would they?

Yeah it`s certainly possible to capture atoms in a pciture but this does seem very HQ

Fake as fake can be faked. Scientists just managed to photograph the shadow of an atom a few months ago ... and we`re to believe detail like this? Nuh-uh. Sorry. HEAVILY-CGId reproduction at BEST.

How did they manage to photograph atoms in such high detail? Is this CG?
