Mind-bender: The observable universe has ~10^80 atoms. But even a simple 1000×1000 black‑and‑white image has 2^{1,000,000} ≈ 10^{301,030} possibilities — and 24‑bit color explodes to ~10^{7,224,720}. The space of (small) images dwarfs the cosmos. 🔬🧪💻

Day four of #LISH25 begins with a powerful presentation by @loicaroyer.bsky.social on digitizing zebrafish development, combining light-sheet and single-cell data. Loïc took the #walk-up song to another level, improvising on the piano as his massive fish development visualisation played. Beautiful.

Production has started for a new #Snoutscope objective, AMS-AGY v3. It has significantly larger FOV and some other tweaks from v1 and v2. Currently accepting pre-orders. The price will need to increase modestly after deliveries start late October.

Just pushed a 'hot fix' version (2025.6.25.2) of Omega (napari_chatgpt) that addresses some issues introduced by the ever-changing model lists from #OpenAI.

I just asked #Claude 3.7 to make a web version of the 'Global Thermonuclear War' game from the classic #WarGames movie from the 80s. And it is not too bad!! Except for its skills at drawing continents... Game play could be more engaging too... haha.
