Re: [FRIAM] sum of atomic spectra == 9000K black body?

I suspect the shape of the curve is due to adding up a whole bunch of unrelated things with some lower wavelength boundary, just like the "law of large numbers" theorem, that shows adding up random numbers gives a normal distribution (bell-shaped curve). The same might be said of the black body

When I worked at the PIttsburgh Supercomputing Center, a division of CMU, we had a user who produced a visualization of the first few milliseconds after the big bang. How can they do that? Didn't Penzias and Wilson win the Nobel Prize for showing that the background radiation caused by that

Jon -- It's a mystery to me. I believe they are simply counting the number of spectral lines at each wave number and plotting the histogram. And the link is between the now and the very long ago. And I believe there's no reason to expect this histogram to have any particular distribution at

Roger, I get the sense that this is a link between the very small and the very large, but I am far from being a physicist. Could you say more about this result? Jon .-. .- -. -.. --- -- -..-. -.. --- - ... -..-. .- -. -.. -..-. -.. .- ... . ... FRIAM Applied Complexity Group listserv Zoom
