illustrating how mDFD can apply directly to a dose-response for a "brighter" light

Agreeing that we need better names, I would add that it bugs me when people say the human L-cone peak is "red". It looks to me much more like "yellow", and then it's only via L-M opponency that we get the "red" color response?

I am so sorry. 💔

This is a business model problem. Supporting a niche device for a long time is very expensive.

Yet to come, I will post a followup when I have it.

LLMs train with trillions of tokens to do something akin to “brainstorming” but then we try to do safety/inhibition with a few paragraphs of system prompts? Think about all the corrections you get in high school, it’s more than a paragraph.

Is there a way to disable the quippy summaries but keep access to image and other features? The one big toggle seems to control it all.

Interesting - it’s in chick embryos so the light goes through a shell. For humans, light is highly attenuated at depth in tissue, and our newborns take some time to develop circadian rhythm.
