Unfortunately, it bombed a Columbia entry level astrophysics exam (designed for non-stem students)[0] It appears it does math worse then college freshmen! :-P Students averaged 75.6% - ChatGPT got a 73.9% Really surprises me how bad it seem

Hmm - I'm not a fan of active cooling solutions (peltier, water, etc). Unless really well done, a failure leaves you with basically zero cooling. I like a nice big chunk of metal! it ain't sexy, but its quiet and reliable.

Correction: Wolfram Alpha seems to use 'new style' if you use the 'Natural language' input, if you use 'math input', it sets it up as an 'old style' equation.

I didn't realize that was the official name..I just thought it was a region thing.

TIL: there is 'old PEMDAS' and 'modern PEMDAS' ... The 2 things I found really interesting about this is: 1. They give vastly different interpretations 2. 'Modern' PEMDAS really appears to be a result of

Hmm..ok - thank you. I'm gonna have to work on that more, atm I'm having a hard time comprehending how volume can increase without density decreasing. To google! Thanks!

Hmm...This goes beyond what PBS space-time taught me about it :-) My understanding was we have more space (eg space is expanding) but the 'vacuum energy' is staying constant.. If I understand what you're saying, that statem

The thing I don't get with that analogy is the ballon IS expanding into something - eg if you put the balloon in a cup, it won't expand (unless you have REALLY strong lungs :-) ). Also, curious where the extra energy comes from to

Personally, having used COBOL for what it was intended (accounting systems), I didn't really mind it. It was verbose, but so was everything back then. I also really liked being able to read DDL directly from the file on the AS/40

Basically, the residents didn't want 'HOA's and municipal regs/taxes. Then overbuilt, sucked the water table dry and want Scottsdale to bail them out. Oddly enough, dip-shits were still buying home there for 500K plus

IIRC, that swapped a few years ago...Millenials are now the largest cohort followed by Gen-Z, Boomers and then Gen-X. Given Gen-X is both the smallest and next cohort to start retiring, I'm guessing medicare, SSI, etc. will have a few

Thought it was interesting what chatGPT got right, and what it got wrong. Counter to my intuition, it seemed to have issues with the math in this exam designed to be 'math lite' class for introductory Astrophysics.

I'm guessing they don't want to end up like MS's last (2? Can't find the other one)(1) or Meta's attempts at online chatbots/ai?(2) I'm guessing OpenAI just doesn't want the bad press... 1) h

I got the same feeling... Reminded me of COMAL(1) with the turtle graphics 'hook' to get kids immediately interested. I actually have some fond memories of teaching Comal to grade school (8-10 year old) kids :-) 1) https:/&#

I miss everything being a 'new challenge'... Outside of accounting systems - pretty much everything was new ground, greenfield, and usually - fairly interesting :-)
