Cell Size and Scale (Awesome Illustration)
 

Move the slider and be amazed by the scale of things

Zoom in and out a couple of times for a better effect

nice link, thanks, super smallness is interesting to think about :2 cents:

pretty cool indeed :thumbsup

That is cool! :thumbsup

Thats really cool! Cheers!

Yeah that was a cool link.

i thought an atom was way smaller than that

very kewl :)

Have you ever really "scene" an atom? Nobody has... because they can't be "seen" with any technology we have today.

Very cool illustration :thumbsup

very educational. Amazing illustration too

Interesting scale and comparison :thumbsup

That was great, just played with it for the last 5 mins

That is pretty cool!

That was fun.

Interesting

Nice link for me, since I do medical animation. Thanks.

thats not true.

I like the ass hairs sticking out of the E. coli bacterium aka mini shit clump.

that is pretty cool :thumbsup

Um yes it is... Not withstanding all the physics books I read and just finishing my 4th quantum theories book I know for FACT it is true.

"...it is actually impossible for anybody to "see" an individual atom since all atoms are thousands of times smaller than the smallest light waves we can see using our eyes... even though they cannot be seen directly with our eyes there is so much evidence for atoms, and we know so much about them, that it is impossible to say they do not exist."

You cannot "see" anything smaller than the shortest wavelength of light detectable with the human eye. The shortest wavelength, violet light, is 4 x 10-7 meters. An atom is about 10-11 meter. So an atom is 4 x 104 or 40,000 x too small to be seen.

HOWEVER...

There are ways to "visualize" it, like Atomic Force Microscopy. But these are all just measurements converted to computer images, and are not in any real sense "seeing" the atom.

AND

There are imaging techniques such as STM that allows you to see the shapes of atoms, BUT it is determined only by the shape of the electron cloud surrounding it.

So again, at present, no one has ever SEEN an atom, let alone with the human eye. The closest approximation is a mathematically measured computer generated image, representation or model.

I could go on but I am sure you didn't even get through that.

ok.... i stand corrected.. there are images of atoms.... i guess it all depends on how you choose to define "seen an atom".

Carbon atom was cool.
Isn't that one of the basics in everything?

Well there is only one definition of seeing anything, other than the perception of the observer.

Now detecting on the other hand, that is the key word here. We detect the presence and existence of atoms in the same way we determine the chemical properties of objects 100's of light years from out planet through spectroscopy, which most times the object being measured ALSO can not be seen.
