Christian Lawson-PerfectReally chuffed to see an article on the BBC about 2024's <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> winner and World's Most Interesting Mathematician, Angela Tabiri: <a href="https://www.bbc.co.uk/news/articles/c5y80n9jdj5o" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.bbc.co.uk/news/articles/c5y80n9jdj5o</a>It mentions <a href="https://mathstodon.xyz/@aperiodical" class="u-url mention">@aperiodical</a> by name!

Christian Lawson-Perfect<a href="https://mathstodon.xyz/@Ayliean" class="u-url mention">@Ayliean</a> now that I'm feeling well again, I'm finally watching your <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> video. It's great!Abbreviating 7 to se'en: I do this! (but only in my head)Furthermore, I shorten every number up to 40 to one syllable. At some point I started counting to 40 in my head, and now I'm pretty much always doing it.

Christian Lawson-PerfectI've got a day off both work and <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> admin, and the sun's finally come out.I think I'll go out on my bike, but where to?

Christian Lawson-PerfectIt's a dreadfully rainy Saturday here, so <a href="https://mathstodon.xyz/@Ayliean" class="u-url mention">@Ayliean</a>'s <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> craft activity has come at just the right time.<a href="https://aperiodical.com/2024/07/the-big-internet-math-off-2024-quarter-final-4/" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://aperiodical.com/2024/07/the-big-internet-math-off-2024-quarter-final-4/</a>

Christian Lawson-PerfectToday's <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> match hasn't had many votes, which is a shame because they're two lovely mathematical thoughts.If you've got a moment, go and have a look, and let us know which one you liked best: <a href="https://aperiodical.com/2024/07/the-big-internet-math-off-2024-quarter-final-3/" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://aperiodical.com/2024/07/the-big-internet-math-off-2024-quarter-final-3/</a><a href="https://mathstodon.xyz/tags/maths" class="mention hashtag" rel="tag">#maths</a> <a href="https://mathstodon.xyz/tags/math" class="mention hashtag" rel="tag">#math</a>

Christian Lawson-PerfectOh wow, someone posted the <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> to <a href="https://mathstodon.xyz/tags/Metafilter" class="mention hashtag" rel="tag">#Metafilter</a>!

Christian Lawson-PerfectTwo days until the <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> starts, and it's starting to come together! The competitors have sent in some really good stuff already, and that's only half the pitches in round 1!

Christian Lawson-PerfectFour days until the <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> starts!

Christian Lawson-PerfectI'm running the <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> again, this July.The Big Internet Math-Off is a just-for-fun tournament that I and a few friends have organised on <a href="https://mathstodon.xyz/@aperiodical" class="u-url mention">@aperiodical</a>, ostensibly to find the World’s Most Interesting Mathematician.Some great people have already signed up but I still need a couple more to complete the list.I'm particularly keen to represent a range of genders, nationalities and backgrounds.There's more information about the competition at <a href="https://aperiodical.com/please-take-part-in-the-big-internet-math-off/" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://aperiodical.com/please-take-part-in-the-big-internet-math-off/</a>If that sounds like fun and you'd like to take part, please tell me!UPDATE: I now have 16 competitors. The Math-Off is go!

Christian Lawson-Perfect<a href="https://mathstodon.xyz/@standupmaths" class="u-url mention">@standupmaths</a> I'm looking through old <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> posts and saw your one about the projective plane: <a href="https://aperiodical.com/2018/07/the-big-internet-math-off-round-2-matt-parker-v-jo-morgan/" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://aperiodical.com/2018/07/the-big-internet-math-off-round-2-matt-parker-v-jo-morgan/</a>Did you ever get that animation re-made?

Christian Lawson-PerfectIf you think you can show me some fun maths and will have some free time in July to demonstrate it, or you can recommend another interesting mathematician, DM me. <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a>

Christian Lawson-PerfectThe poster from the last proper <a href="https://mathstodon.xyz/tags/BigMathOff" class="mention hashtag" rel="tag">#BigMathOff</a> is still on my office wall. One day I'll have the energy to run it again!
