I just submitted my abstract for the #AI and the Future of #Math seminar: Title: You are right, and I apologize. Abstract: Doing research changes the researcher. In this talk I will try to document my personal story with AI. I love computers and have been an early adopter of AI with a mostly positive outlook onto the future. Recently the picture has become a lot more grim. This has two reasons. The first is that it is becoming clearer every day how we simply cannot extend the trust that we naturally have between mathematicians also to big tech. The second reason is that I observe changes in myself that I don't like. I used to say that writing is thinking and I still believe it is true. But I also outsourced a lot of writing to the machine, feeding it notes and unfinished thoughts and then editing the result to sound more like me. For certain texts (like bureaucratic letters) this is certainly an efficient and acceptable way to proceed, but for my core thinking I want to learn to accept that this is a slow and messy human process. Disclosure: I have written this abstract without any AI usage. It took about 30 minutes. I used emacs. The talk is Nov 3, so still plenty of time for things to happen. https://www.uni-muenster.de/MathematicsMuenster/ai-math/

1/9 #MathsMonday Today I'm going to talk about adding/removing brackets, for 2 reasons...

  • people prematurely remove them
  • people adding them incorrectly In #Mathematics we have many things which are the opposite of each other - add/subtract, multiply/divide, factorising/expanding - and so it is with brackets in #Math also. This is because if someone has put together an expression from a number, the rules of #Maths have to make sure we follow the exact opposite steps to get the same number...

1/7 This week for #MathsMonday we are going to debunk the "implicit multiplication" (IM) claims (and also look at the mnemonics). I say claims, because there is actually no such thing as IM in #Mathematics. I find invariably the people who say there is have forgotten The Distributive Law (TDL) and/or Terms, but most often both! As we have already seen, these are both rules of #Maths, taught in many #Math textbooks, so that right away debunks any claims that "there is no convention in Maths"...

@DevWouter@s.poweredbydev.com @mattgoldman@mastodon.social both got the correct answer of 1 - well done! Let's look at the correct working out, then delve into where people go wrong with their #Maths #math 8/2(1+3) =8/(2*1+2*3) =8/(2+6) =8/8 =1 Also acceptable is... 8/2(1+3) =8/2(4) =8/(2*4) =8/8 =1 If you've seen someone say that it's ambiguous, it isn't - we shall see in coming weeks that #MathsIsNeverAmbiguous they have simply forgotten one or more #Mathematics rules First, #DontForgetDistribution the Distributive Law...

1/10 This week for #MathsMonday I'm going to talk about #calculators, in particular the current topic of #Mathematics order of operations (which I am nearly finished with now), and e-calculators (I'm looking at you #Developers #Programmers). It's important to know where brackets go in #Maths expressions, and after last week's topic I ran a follow-up poll https://dotnet.social/@SmartmanApps/111145907574869556 to see how many people could remember the #Math FOIL acronym from High School, because I sensed a deeper issue...

#Mathematics #Maths #Math #Poll Do you remember the acronym FOIL from High School? i.e. what it stands for/how to use it Please boost for reach Thank you to those who voted. The result of this is discussed in https://dotnet.social/@SmartmanApps/111145907574869556 (also includes textbook screenshot of what FOIL is 🙂 - it's First, Outside, Inside, Last. i.e. multiply those terms in adjacent brackets in that order) [ ] Yes [ ] I'd forgotten about it... til I saw this poll! [ ] Sounds vaguely f

1/6 I have a #MathsMonday #FactFriday cross-over event post for you this week 🙂 The #fact is that #Mathematics is universal. We may use different notation in different countries, but the underlying #Maths is the same everywhere. i.e. there is nothing "arbitrary" about #Math I saw someone question if there might be "different" Maths somewhere else in the universe. No. If I have 1 thing, and I get another thing, I now have 2 things. i.e. 1+1=2 (or your country's notation)...

#MathsMonday week 2, Terms. Simply put, in #Mathematics Terms are separated by operators and joined by brackets. The most common example is 2a=(2*a). This makes it simpler to write fractions. e.g. 1/2a rather than 1/(2*a). That also means 1/2a isn't mistaken as half a, which would actually be written as a/2. Notice in the latter that the a is to the left of the division, which means it's in the numerator, and vice-versa for the former (more about this aspect of #Maths #Math later, but first)...

1/6 #MathsMonday 1917 (part 1) - Left Associativity I have seen many people who argue about this #Mathematics issue that refer to changes in 1917, and I started to research it this week. The #Maths change I thought was made, I have not been able to find any reference for it, and that is about /2(1+3) vs. /2*(1+3). Apparently in pre-1917 #Math the latter was also considered to be a single term (in the denominator) but now is 2 terms. If anyone has a reference for that then please let me know...

Mathematicians are facing the sudden shift with grief, anger, and a desperate search for fresh ideas: “If we don’t adapt, there’s just no more math in 50 years.”

#mathober is starting today – one math prompt per day to express yourself in some way! https://www.fractalkitty.com/mathober-2026-prompts/ Day 1: "Perimeter of an Ellipse" Calculating the perimeter requires elliptic integrals. But I learned about a pretty efficient method to approximate it, which uses the arithmetic-geometric mean! In my drawing, all ellipses have the same perimeter! Imagine squishing and stretching a piece of wire. Coded in #p5js, then drawn using #krita. #math #mathober2026

this is the back of one of my new Mandelbrot knit sweaters https://knityak.com/collections/antenna-crown in shades of blue. these ship with the code in Python to generate your specific spot on the Mandelbrot fractal with these same four colors and dithering. these are made with a new on demand manufacturer and are pixel native from my code: one pixel equals one knit stitch. #math #knit #computationallyfabulous #fractal #mathart #algorithmicart
