Simon Tatham<a href="https://hachyderm.io/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> question: is there any good collection of all the knowledge about Conway's "nimbers"? I've found any number of beginners' explanations, but nothing further.(I mean the thing that makes a field of characteristic 2 out of ℕ₀, with addition corresponding to bitwise XOR, and multiplication a really weird inductively defined thing, such that every initial segment of ℕ₀ of size 2^{2^n} forms a subfield.)I was idly playing around with them recently – wrote a tiny Python thing to implement their multiplication. I happened across the fact that in each of the first nine of those finite subfields, the _largest_ integer in that subfield – 2^{2^n}-1 – generates its whole multiplicative group. That is, 3 has order 3, 15 has order 15, 255 has order 255, … up to and including 2^512−1.Is that true for all n? I'm curious to know if this is a known result, or at least a known conjecture. Seems to me it would be pretty neat if it were true, because it would give you a "canonical" choice of primitive polynomial over GF(2) of degree 2^n – just take the min poly of the corresponding nimber.By my calculations, the first few of those polynomials (in the usual binary representation where 2^n stands in for x^n) are 3, 7, 25, 425, 101021, 7158330089, 27971386341277386797. But OEIS doesn't know that sequence, so maybe this isn't known?<a href="https://hachyderm.io/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://hachyderm.io/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a>

Paysages Mathématiques"We mathematicians need to put far greater effort into communicating mathematical ideas.

Paysages Mathématiques"[Mathematical induction] is a tool that allows us to move from the finite to the infinite. This tool is always useful because it allows us to skip as many steps as we want, sparing us long, tedious, and monotonous verifications that would quickly become impractical. However, it becomes indispensable as soon as we aim at the general theorem, whose analytical verification would bring us closer and closer [...]" – Henri Poincaré (1854-1912) <a href="https://mathstodon.xyz/tags/quote" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#quote</a> <a href="https://mathstodon.xyz/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> <a href="https://mathstodon.xyz/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://mathstodon.xyz/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a> <a href="https://mathstodon.xyz/tags/induction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#induction</a>

Virgile AndreaniI nerd sniped myself on the following problem today: There is a secret number between 0 and 1, you can send guesses to an oracle who will tell you whether the number is higher or lower than your guess, BUT the oracle always answers in a time proportional to your guess. If you know that the number is between a and b, what should be your guess to shrink the interval as fast as possible? I found asymptotic solutions for the limit cases a<<a href="https://fosstodon.org/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://fosstodon.org/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a>
