Theorem of the Day
- brosirmandude 10y agoThis is really interesting, but my heart hurts at the SEO value lost in having the main content be all PDFs. Not that there's really a NEED to have all of this crawl-able & indexable by search engines, but it could probably reach a whole lot more people if it was.
- pmiller2 10y agoPretty cool, but the links don't work for me. I'm on Windows 10, Chrome 54.0.2840.71 64 bit.
- Dinius 10y agoWin10, Chrome 54.0.2840.99, works fine here. (They link to PDF files though, more likely that's the problem I suppose).
- pmiller2 10y agoYeah, I restarted Chrome and everything is good again. When in doubt, turn it off and back on, right? :)
- ivcha 10y agoPerhaps you can kill a bunch of birds (especially those that hurt your privacy :)) with one stone: install Firefox ;)
- godelski 10y agoWould be kind of fun to get this in email. Kind of like word of the day.
- sohkamyung 10y agoI second that, but my preference would be for a RSS feed. Edit: they do have a RSS feed and other ways to get a daily theorem from their Resources page [1] [1] [ http://www.theoremoftheday.org/Resources/Resources.htm http://www.theoremoftheday.org/Resources/Resources.htm ]
- godelski 10y agoWould you look at that. That's good enough for me, thanks. Though are you getting the full pdf's? I'm using Sage and a lot are linking to PDF's with "A newer version of this theorem description is now being hosted at: www.theoremoftheday.org/Theorems.html" Also some are linking just to the home page. I'm wondering if this is just me or you're getting the same.
- sohkamyung 10y agoOh dear. Yes, I'm getting the same "A newer version of this theorem..." PDFs. My apologies. I should have checked that the RSS is returning valid links.
- godelski 10y agoWell it is good enough, was just checking. Thanks.
- Fice 10y agoYou can use an RSS feed to email converter. I use Feed2imap (https://github.com/feed2imap/feed2imap/ https://github.com/feed2imap/feed2imap/) to collect feeds from many sites and Notmuch (https://notmuchmail.org/ https://notmuchmail.org/) to sort and index the mess.
- vanhodji 10y agoThis is super interesting. I love how concisely they are able to convey a certain concept. I feel the ratio: amount of knowledge you acquire versus length of the explanation is incredibly high, which makes me want to keep opening more and more tabs. The only place where I have the same feeling is in fermatslibrary.com, although in a different way. I would like to see the same concept applied to CS.
- tEMporality7 10y ago> I would like to see the same concept applied to CS. Definitely. An algorithm of the day would be nice.

- keyle 10y agoUnrelated: when a site gets top of HN and it's made of PDF contents, I just cringe at the bandwidth usage for the next few hours...
- metafunctor 10y agoNah. These PDFs are look to be about 150K-300K. A typical bloated 2016 web page has an equal amount of JavaScript, let alone images, so not really worse off using PDFs. Assuming (generously) a 100k visitors at half a megabyte per visitor, a top HN placement will only cost a few dollars in bandwidth.
- oggy 10y agoFor more random interesting theorems with outrageously clever and beautiful proofs, the "Proofs from THE BOOK" [1] book is a fantastic collection. As a curiosity, "THE BOOK" in the title comes from Erdos, who often referred to the book in which God keeps nice proofs of math theorems :) [1]: https://www.amazon.com/Proofs-BOOK-Martin-Aigner/dp/3642008550 https://www.amazon.com/Proofs-BOOK-Martin-Aigner/dp/36420085...
- thomasahle 10y agoAm I the only one who was confused what the 'tau' referred to in http://www.theoremoftheday.org/NumberTheory/Willans/TotDWillans.pdf http://www.theoremoftheday.org/NumberTheory/Willans/TotDWill... ?
- osoba 10y agotau = 2*pi
- thomasahle 10y agoI wish the authors would include a small note "tau = 2*pi". Maybe one day it won't be necessary, but for the foreseeable future it would quite increase readability.
- biofox 10y agoI was also confused. Personally, I find the use of tau nonsensical -- especially when it's used alongside pi. Established conventions should only be changed when there's a clear need to do so. Inventing a redundant constant does little other than add additional cognitive load. It's not like the tau advocates can break backwards compatibility -- there's too much literature that uses pi. The result is that everyone must now remember both pi and tau.
- osoba 10y agoI think tau was used on purpose in that article to avoid confusion with the prime counting function, typically denoted pi (unrelated to the constant pi)

- maxiepoo 10y agoI disagree with the front page of this site, the "crowning achievements of mathematics" are not "her theorems", but our definitions.
