Ephemeris: 05/08/2025 – AI, a different way to compute

May 8, 2025 Comments off

This is Bob Moler with Ephemeris for Thursday, May 8th. Today the Sun will be up for 14 hours and 33 minutes, setting at 8:56, and it will rise tomorrow at 6:21. The Moon, halfway from first quarter to full, will set at 4:51 tomorrow morning.

This week we’re investigating artificial intelligence or AI. My software experience in my career with computers is that of financial software for banks including ATMs and various other machines that have to do with banking, so AI or anything scientific was completely out of my realm. So I’m kind of looking at this like is an interested layman with some knowledge of computers. AI uses neural networks which is something that most computers don’t have. It can be simulated digitally, although I understand that they have chips that actually are neural network components. Neural networks are how the human brain functions with neurons and synapses. How they’ve gotten it to work, I have no idea.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.

Addendum

I asked Gemini, Google's AI, to draw a neural net
I asked Gemini, Google’s AI, to draw a neural net. I got this background image. Then I asked for a schematic of a neural net, and I got the schematic with the first answer’s background. Created by Google Gemini.
Nanoscale-resolution of the structure of the human cortex.
A partial recreation of “The Lichtman laboratory at Harvard University and the Connectomics at Google team are releasing the “H01” dataset and companion paper. H01 is a 1.4 petabyte volume of a small sample of human brain tissue. The sample was imaged at nanoscale-resolution by serial section electron microscopy, reconstructed and annotated by automated computational techniques, and analyzed for preliminary insights into the structure of human cortex.” This was an animation the build up by adding more and more nrurons. I took the screenshot before it got too overwhelming.
