A nice book about octopus and cuttlefish. I was surprised to learn they live only about 2 years. Yet they have big brain. They don’t have color vision yet easily camouflage with colored patterns. Cuttlefish display colorful patterns.

Apparently Google’s Gemini 2.5 has an IQ of 130. Hope this is a real reflection of intelligence??? Could we have bot Einstein quite soon?

Fern leaf emerging from simple rules. This is a fun example I show at the end of the semester of Classical Mechanics. Behind complex phenomena, there might be simple reasons.

Just finished a class on contour integral. I was curious if ChatGTP o1-preview model could solve this. The modelwent through reasonable steps but could not arrive at the correct answer. So for now #AI is far from surpassing human intelligence.

Got the comet at my backyard! RedCat51, ASI533MC, 1 minute. Comet Neowise started my fascination on night sky, but I did not see it at the time. It feels great to be able to finally image and see a great comet!

Moved the 8”Dob to Pennsylvania, the sky is much darker here. Visual astronomy has its own charm.

GTP-4o image generation is far from good. Nice treble clef, but at least know there are 5 lines

OpenAI just dropped a new model, o1 preview. I give it a graduate level classical mechanics problem. It answered flawlessly. Very impressive. #AI is progressing with amazing speed!

Eagle nebula M16, 5 hours with RedCat51, ASI530MC, processed with SiriL. Good to do this again after more than a year off. #astrophtography

For synaptic conductance, I always have used the kick and decay model, which ignores the activation time of the AMPA receptors. Now I found the paper behind it. Jonas showed that the rise time of EPSC is on the order of 0.5 ms. This is at 22 C! It should be even faster at 36 C. Nice paper!
