Suat AyözI'll be posting the questions from AMS 2025 Daily Epsilon of Math Calendar daily from now on. I should have started earlier (doing it on Blue sky for some time). Hope it will be of interestHere's the question for April 13th. For those unfamiliar with the calendar, the answer is always the day of the month. Looking for imaginative solutions is the aim. <a href="https://mathstodon.xyz/tags/mathstodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathstodon</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/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> <a href="https://mathstodon.xyz/tags/MathsToday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MathsToday</a>

TrebethericAmikoj who like maths: I'm trying to find the name of a math operation. Please help if interested!It's similar to "choose" 4 choose 2 = 6 because there are six ways to choose 2 things from four. Similarly, 5 choose 2 = 10 There are ten ways. But what if the five things are in a circle and we don't (re)count as new instances the ones that look the same when rotated? 5 ___ 2 = 2 (I'm pretty sure) The 2 items can be either 1 and 4 apart or 2 and 3 apart. I'm looking for the underlined operation. 5 ___ 3 = 2 If the items are ABCDE, where E is connected to A, the two configurations are 1. ABC (three together), 2. ABD (two, skip one, one). In the case of 5 items ACD is equivalent to 2 because CDA is two, skip one, one.For my purposes they must be equivalent by rotation only, not by flipping.6 ___ 3 = 4 ABCDEF has ABC, ABD, ABE, and ACE. All others should be equivalent if I counted correctly. What is this operation called? 🙏<a href="https://mastodonapp.uk/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a> <a href="https://mastodonapp.uk/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://mastodonapp.uk/tags/discretemath" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#discretemath</a> <a href="https://mastodonapp.uk/tags/permutation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#permutation</a>

doboprobodyne<a href="https://mastodon.social/@glyph" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@glyph</a> I hear you.My favourite (perhaps less jarring?) example is when a court declares they have found someone guilty, and that their threshold of guilt is "on balance of odds".I look at the lawyers and the witnesses and realise that none of them has studied actuarial or probability mathematics. I wouldn't even trust them to understand a bet on the horses. For a scientist to watch them is like observing a cargo cult. Worse, I am sure, is for a scientist to find themselves on the receiving end of such a court.I would offer the meagre consolation that you can see the feedback loops that drive them to behave so, where they think themselves to have free will.<a href="https://mathstodon.xyz/tags/cybernetics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cybernetics</a> <a href="https://mathstodon.xyz/tags/actuarial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#actuarial</a> <a href="https://mathstodon.xyz/tags/odds" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#odds</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/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://mathstodon.xyz/tags/statistics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#statistics</a> <a href="https://mathstodon.xyz/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://mathstodon.xyz/tags/scientificInquiry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#scientificInquiry</a> <a href="https://mathstodon.xyz/tags/systemsArchitecture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#systemsArchitecture</a> <a href="https://mathstodon.xyz/tags/justice" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#justice</a> <a href="https://mathstodon.xyz/tags/law" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#law</a> <a href="https://mathstodon.xyz/tags/policing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#policing</a> <a href="https://mathstodon.xyz/tags/cargoCult" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cargoCult</a>

BenjohnCan anyone suggest good tutorials for learning an intuition and working with the exterior product of vectors and multi-vectors in general? Having access to an oriented area (and other oriented objects beyond just directions) seems very powerful. I've been trying to learn it and show my kids some bits of it, as it seems potentially more learnable than just "vector algebra": there's more there to connect together – the concepts are reinforced by carrying through in to more places?Anyway – a pedagogical approach to this would be splendid.
