Comment Re:Cooling is easier in a vaccum?? (Score 1) 90

You're right about radiative cooling - I didn't consider that radiative cooling would be that much easier.

I asked claude.ai a bunch of questions.below According to it, purely radiative cooling of a device in space (40-60C) is roughly as effective as very crude conductive cooling of a similar device on earth (internal temp 49 C).

_---------_
Consider a 1 m radius spherical object in LEO. One direction, bathed in direct sunlight is coated with solar panels. The electricity generated runs computers internally - the computers are capable of running regardless of the internal temperature of the enclosure. The reverse side is exposed to the 2.7 K of the CMB and had small metal radiative panels.

Compare it to another similar size sphere stored in a room at a constant 22C on earth. Instead of solar panels, the same amount of electricity is pumped in.

In which case would the internal temperature of the sphere be higher?
Make a few assumptions about the other parameters. All power generated by the solar panels in space, or fed in by power lines on earth is immediately used for computation.

Give me rough internal temperatures for both cases

Now assume the sphere on earth is (a) suspended on a thread (b) half buried (c) fully buried , and it has a metal body.

Earth.c 49 C

I found GP2.5 to be great at academic-style research and writing; it was absolutely awful at writing code. So; I would tell it to plan some thing for me and write it in a way that could be used by another agent (Claude Code) to build the code to do the thing. In this way, it has been great! I haven't yet attempted it with 3.

That said, I found GP3.0's page to be hilarious:

It demonstrates PhD-level reasoning with top scores on Humanityâ(TM)s Last Exam (37.5% without the usage of any tools) and GPQA Diamond (91.9%). It also sets a new standard for frontier models in mathematics, achieving a new state-of-the-art of 23.4% on MathArena Apex.

It then proceeds to show, lower down on the page, an example of what it can do, by showing off 'Our Family Recipes". If there's anything that touts PhD-level reasoning and writing, it's a recipe book.

My kids were born in the 1990s and my youngest daughter was in her early 20s when she was talking to a cousin 10y younger than she. The cousin had asked about a sweatshirt she was wearing that had cursive text - nothing complicated, probably "dogs are cute" or somesuch - and my daughter AMAZED her by being able to read the script.

Then the cousin asked "It's cool that you can read that, can you speak it, too?"

Yeah, I'm not sure mandatory cursive classes are going to help at this point.

my son's teacher told us that it helped with developing fine motor control, particularly in children that had below average motor control.

For one, is this based on research or speculation? Second there are different kinds of motor control. Following an existing pattern or shape is one type, while cursive is another because one tends to develop patterns based on personal preferences.
