I teach college math. And, I have been fooling with computers and open-sourced software for far too long. For my free math texts and contact information see https://hefferon.net.

jimhefferon··on Making AI better at math tutoring
Oh, bless you, that's very kind. I am proud of it and I think it is very good for its intended audience. But almost no one has read it, that I can tell.

I wonder if you have any experience in teaching at the primary level?
jimhefferon··on Making AI better at math tutoring
Thanks, but it happens that I've tried NS but didn't love it. But I appreciate the question answer.
jimhefferon··on Making AI better at math tutoring
I am in agreement with a great deal of what you say, except that one thing is missing. Five years ago it was not possible to look at what systems were around and suppose that AI could be the tutor. I see posts arguing that this is not a good tutor, fair enough, but at least some reasonable and capable people think it is.

Following that trend line, it seems quite possible to me that in five years AI will be the teacher. (Of course it may replace CEOs also.)

And it can answer in LaTeX.

Cool idea. Suggestion: side-by-side output.

jimhefferon··on It pays to be a double major in college
I'm a college faculty member. I'll just note one thing in my experience. Everything in life involves tradeoffs and this is not an exception. I have often seen people unable to take something they were interested in because a second major means a lot of juggling. If they are okay with that, then that's fine of course.

Sure, this week. What about next week?

Math teacher here. Gulp. :-)

Seriously, though, its impressive.

Well put. It is fun.

Ok, that's fine but that's not what he does.

Sorry you can't run. Best wishes.

Just a note to encourage you to see a physical therapist, before deciding that there's nothing to do. I've been a jogger since 1971, started having back pain all the time. A physical therapist gave me 15 minutes worth of exercises everyday. Pain gone. Good luck!

I'd be interested in code if you produce something you like.

You could have a look at https://hefferon.net/computation which is certainly aimed at a broader audience.
jimhefferon··on The design philosophy of Great Tables
Thanks. I've not seen that particular post.

I just made a table this morning for Calc II notes. The first column says something like $f'(x)$ in the first row and $f'(0)$ on the second. The table body lists values for different functions, one per column. I put in a column rule separator because the leftmost column seems separate from the others.

In any event, I'm suspicious of rules (pun noted).

jimhefferon··on The design philosophy of Great Tables
I'm interested in the midcentury modern ones because they have lots of vertical rules. I'm active on the subreddit for LaTeX and there is a religion common there that even one vertical rule is an unforgivable abomination.

I'm not sure it is fair to claim that the Gov is behind the white paper, in that paying for a study is different than a program to develop malicious code.
jimhefferon··on Show HN: I made a cheap alternative to college-level math & physics tutoring
I just moved to a new college. At my prior place, I might see one student in hours in an entire semester. Here, in hours there are usually two or three each session. So yes, it varies.

Thank you, that's an interesting link.

What is the site? I was interested by the page but the site won't let me in without registering.
jimhefferon··on How smart do you have to be to get a degree?
I have not seen anyone say this, so I will (apologies if I missed someone's comment). It is not clear that IQ is a good measure of smart.

I'll also note that when I teach Elementary Statistics and ask undergrads for a show of hands of who has taken an IQ test, often in a class of 30 I won't get more than a hand or two. So I guess these studies are administering the tests specially for the study?
