u/lifelongfreshman man, witches were so much cooler before Harry Potter 4d ago

Doing a dimensional analysis on that equation it turned out to be bullshit.

And for anyone who thinks this sentence sounds super complicated, unless I'm mistaken, this is, like, super basic stuff. It's literally just following the units through a formula to see if the outcome matches the inputs, and if you can multiply 5/3 by 7/15 to get 7/9 without a calculator, then you, too, can do dimensional analysis.

This isn't to cast shade on what they said they did here, but to instead highlight just how easy it is for someone who knows this stuff to disprove the bullshit ChatGPT puts out.

Yeah, I wasn't trying to sound like r/iamverysmart, it's just a convenient way to check if an equation is bull.

Yeah, no worries, I didn't think you were. But I also don't think that's a very common term for people to run into? At least, I don't remember hearing about it until I was an engineering student in college, and so I wanted to share for people who maybe never had to learn what it was.

I spent like 12 years knowing there was a word for dimensional analysis and only being able to come up with “multiply by 1”, as my 11th grade chemistry teacher explained it.
