I finally got around to a little project I promised myself after seeing The Origin Of The Elements on APOD. With a table of the atomic composition of the human body and a spreadsheet, I came up with this:

Very interesting. I’m a little surprised - I naively thought there would be more hydrogen/big bang original material, but I expect the percentages would be a tad different if by number of atoms vs. mass percentage. The Pioneer plaque graphics are appropriate. Nice.

Oh, I just saw the “pioneer.jpg” at the bottom. Is that your way of giving credit? It isn’t really that Jpeg any more, maybe just a small credit would be better? Edit - I see that’s the name of the file.

We really are stardust! And neutron-star dust. And primordial hydrogen and cosmic spallation stuff.
Mix, heat, and let ferment for a few billion years. Do not boil.

Yes, hydrogen dominates in moles, oxygen in kilograms.Originally Posted by Van Rijn
The file name is just my way of tracking this image on my hard drive. The Pioneer plaque image is public domain, so the iconic silhouettes are intended a sort of Easter egg for people (like you) who recognize them. I wanted public domain + nude human silhouette + no sexist choice + relevance to topic. After about ten seconds of reflection, the choice seemed clear.
(OK, there's actually still significant sexism in the Pioneer plaque, part of which is evident in the silhouettes, but the iconic relevance drew me in.)

Lovely work there.
As an addition to the chart, maybe the amount of electrical power our bodies generate that could be picked up by a dish if transmitted?

Probably not. The level of bioelectricity from a human body is barely detectable even a few inches from the skin. It would be quickly lost in background noise at greater distances.

In describing the stardust, we see the stuff, the life within is a bunch of processes and functions, many of which could be detected at a distance in principle. But that is another story.

When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.
