haha - I was waiting for this to turn up here. It's brilliant!

Fascinating stuff. This has to be one of the best scale diagrams I've ever seen.

It's also amazing to think we can produce computer components on the scale of viruses, e.g. the latest 32nm chipset (we'll even reach 11nm in a few years).

What will Orrin Hatch and Moroni think about this kind of stuff being done in Utah?

A very cool little application, I never thought bacteria and viruses were as small as that, the amoeba seems positively enourmous in comparison!

My brother, a graphic designer, saw this site and commented that it was too bad they didn't put the coffee bean and carbon atom next to each other for comparison. I did some quick calculations and told him that at 1200dpi, if the carbon atom was 1 pixel, the coffee bean would be about a half mile (0.8 km).

So size DOES matter?

Can't remember who, on this site, first recommended this http://www.nikon.com/about/feelnikon/universcale/index_f.htm but it's more amazing to me. Thanks, to whomever.

I teach high school biology and have shown this to students in class. One that that confuses me is the apparent size of the chromosome; it looks way too big to fit 23 into that red blood cell! I wonder if they measured only length and just had an artist do the width...

The diagram is completely accurate; an X chromosome unravelled in the shape shown really is that big. DNA normally squeezes into a smaller place by becoming a coiled coiled coil [sic]. The text of the page gives a brief mention of the coiling issue when it explains in detail how the chromosome compares to a sperm.

red blood cells have no nucleus so no DNA, great slide BTW

Most species do have red blood cells with nuclei. Mamals are different (with the exception of the camel)

(Not necessarily a correction.)
Just to make it clear, the chromosome shown is very tightly wound together.
It's typically like that only when cells divide.
In the other parts of the cell cycle large parts of the chromosome is unwound to make the DNA accessible to the RNA polymerase.

The Nikon site is very nice. You may also like this one, which explores the different sizes of things we see when we look up at the sky.

Isn't a bird's egg technically a cell, too?

This is a great tool to help visualize size of biological entities. It also effectively takes you back in time in the Earth's history, starting at 4.5 billion years ago with the atoms gradually building into small chemical precursors for the biological molecules that could drive reproduction and evolution of larger and larger entities.
