jovas··on An index of the OpenAI/math collection
I'm not the creator of this, but I do think it is cool!
jovas··on Formalizing Fermat's Last Theorem
Yes, I'm a mathematician.

But not an expert on this.

While I don't know the specifics, and someone more "in-the-field" than me would recognize all the "named" theorems etc

I am aware that there have been minor issues that have come up with the formalization specifically, and that previous proofs for lower values of n were always needed.

Though it used to be n=5 and lower needed to be checked.

jovas··on My favourite fonts to use with LaTeX (2022)
I like some variant of STIX (I never know the exact difference) and Gillius Sans
jovas··on NASA study reveals Venus crust surprise
Venus has a retrograde day that is longer than it's year.

While the atmosphere is a big problem, even without this issue the rotation would be problematic.

jovas··on Show HN: OpenTimes – Free travel times between U.S. Census geographies
I don't know.... It tells me that by car I can get someplace (that's geography close!) in < 15 min, but it's always taken me 20...
jovas··on "Have Quotes About Salieri"
It upsets me that the only widely available versions of Amadeus now is the "extended edition," which fundamentally alters the film’s core message.

In the original theatrical cut, Salieri is a deeply flawed but fascinating character—a man consumed by jealousy, yet also in awe of Mozart’s genius. His sabotage of Mozart is tragic, not just because of what it does to Mozart, but because Salieri himself recognizes the beauty he is trying to destroy. There’s a complexity there: Salieri hates Mozart, but he also admires him. He wishes, more than anything, that he could be his friend, but he cannot overcome his own bitterness.

The extended edition, however, adds a crucial change: Salieri doesn’t just work against Mozart—he actively humiliates Mozart’s wife, Constanze. This transforms Salieri from a tormented, conflicted figure into something much simpler: a villain. Instead of a man waging a war against God through Mozart, he’s just a petty, lecherous schemer.

The real Antonio Salieri was not some scheming villain—he was a respected composer, teacher, and conductor who mentored some of the greatest musicians of the next generation, including Beethoven, Schubert, and Liszt.

jovas··on Binocular Shot
As a kid, I was really excited to try out binoculars, and "see for myself" the so-called "binocular shot." I was very disappointed.
jovas··on Tips for mathematical handwriting (2007)
Pretty much exactly how I write. (My lower case zeta is prettier)
jovas··on Fermat's Last Theorem – how it’s going
I believe Wiles' proof requires the case of n=3 (Euler), and n=4 (Fermat) separately. That is, Wiles' proof starts with n=5 for nontrivial reasons.

So it is more likely that Fermat saw n=4, and thought the rest would be similar.

jovas··on Amplification of electromagnetic fields by a rotating body
Could it be true for gravitational waves?
jovas··on Enlightenmentware
LaTeX.

I LaTeX, Git, and emacs every day.

jovas··on This USB flash drive can only store 8KB of data, but will last you 200 years
It would be good for storing passwords that you don't want to lose (assuming the USB drive is stored in a safe place.... Like in a safe or under your bed)

Can sweave be integrated with a learning management system?

Ximera allows authors to write online interactive texts, that can serve as the HW system for a class.

The student's work can be directly sent to the grade book via LTI.

Moreover, you can simultaneously produce a PDF that looks like a traditional text.

Which nobody needs to buy, since the PDF generating the text is freely available.

jovas··on Comparing the NYT op-ed to tweets from cabinet members
The high score of VP and POTUS is surely reflective of their speech writers... isn't this backed up by the fact that VP has .8 and mike_pence has -.05?

Regardless, if throw out POTUS and VP, we are left with Pompeo and Ross as the two highest.
