Cool. Thanks.

[Jim S]

Very cool. Thanks.

[Noah]

That is insanely cool.

[stratzrus]

Very interesting, thanks for sharing.

[jaydub69]

Very Cool.
I'd be interested to know how accurate this is. The amoeba seems to be similar in size to the grain of salt. Of course of I know there are different course salt grains...
And I never thought I'd be able to see a human egg with the naked eye unless this is an optical illusion.

Curious, I bet the scale of an electron is that whole scale done all over again, owing to the fact that atoms are made up largely of space.

thanks,
John

nice!!!

A human egg is 130um, which is the same as 0.13 millimeters. You could not see it with the naked eye. It's easy to visualize 1mm as a distance on a ruler. But when something is 1mm x 1mm, it is considerably smaller than you expect. One tenth of that, impossible to see without a microscope.

[RAILhead]

Cool.

[EricPeterson]

WOW. that was cool.

[GAD]

That's very cool. The Museum of Natural History in NYC has an exhibit on a grand scale with a similar principle. That was a real eyeopener for me.

[arthur rotfeld]

Very cool.

I can't figure out why the X Chromosome is so big. I thought that would be MUCH smaller.

[eBay]

Liked it.

[Frankee]

You had me at "science nerd".

[Balok]

love it! Carl Sagan would have done a Cosmos episode with it. And it keeps going waaaay past the carbon atom. There's really no limit to the microverse.

That's answered on the page. Scroll down a bit.

[THebert]

Thanks.

[hellbender]

huh huh huh ....sperm

[jaydub69]

Thanks again Polynitro.

Here's another one going in the opposite direction:

And it keeps going waaaay past the carbon atom. There's really no limit to the microverse.

The Planck length may function as a lower limit. But it's a long way down. That whole slider covered 7 orders of magnitude in size, from a millimeter to 100 picometers. Planck length would be another 25 orders of magnitude - the slider would need to be over four times as long. But there wouldn't be much else to look at. About 3 orders of magnitude down would be the nucleus of the carbon atom, another 2 would get to the size of the protons and neutrons in the nucleus.

The electrons surrounding the nucleus, and the quarks that make up the protons and neutrons, would be at least 3 more orders of magnitude smaller. But, they don't have clearly defined positions in space. The uncertainty of their location is actually larger than their own size. In fact, an individual electron can be thought of as a cloud of potential locations as large as the atom itself. Individual quarks likewise potentially exist everywhere within the nucleus. Quantum mechanics is weird.

There is a really cool book that has a set of pictures, each covering an area ten times smaller than the next, ranging from a wide-scale view of the universe to inside an atomic nucleus. I think they're on the web somewhere too, but it's time for me to go home so I'm not going to Google for it right now.

yeah depends whos eye I guess. Anton von Leeuwenhoek saw a ton of stuff with his POS ghetto scope he made himself...He had very good eyes apparently.
