If you’ve worked with data science, ML or AI tools you will probably be familiar with the KNIME tools. Later this month, April 15-17, 3 days of data science demos will be available, with free online stream passes available. Check it out at https://info.knime.com/spring-summit-2024-atx!
Ideas for the Einstein Mad Hat contest
As you may have seen from Matt Parker’s latest video, there is a new contest for the recently discovered Hat and Spectre tiles! For more details about this recent discovery please see the MoMath article about this “ein stein” (a pun for “one stone” in German).

In recent years there has been a lot of talk about solar and more renewable energy. In USA the recent IRA has provisions for extending solar and renewable energy, and the Florida governor last year supported Solar benefits which turn out to be helpful in many natural disasters, making an energy grid more easily self-sustainable after hurricanes that are common to that state. What if we could go over a map and see what buildings are the best candidates for solar generation? OpenStreetMap has not just street maps, but many other features, including building coordinates, which can give us polygons that can calculate areas for potential solar!

Recently it was noted, by Arstechnica and others, that ChatGPT doesn’t seem to be great at math questions – recent tests have found one can get wrong answers much more often than a calculator, and even apologize if you insist that it is wrong (suggesting it doesn’t know math after 2021… lol). but what about other similar assistants?

In recent months, new inventions like ChatGPT have been said to be possibly the end of society, or the saving of society… but maybe this is something that is something very similar to what has been hyped before?

In a recent newsletter, well known scientist Katherine Hayhoe mentioned a listing of the top most efficient computers – while efficiency is something to consider in your purchases, is there really a big difference in which laptop you buy and use?

In a previous post I showed some interesting facts about Zipf’s law and how many different things show a pattern of logarithmic decrease with the most popular or numerous item largely being much more so than the very rare ones – in a logarithmic pattern. Let’s look at that pattern and how you can chart it…

Today is Tuesday, Pi day (3/14)! Pi day is a national holiday celebrating mathematics, pi, and yes sometimes some baked pie and Pi-zza…
As 3/14 is a Tuesday, so are April 4, May 9, June 6, July 4, August 8, September 5, October 31, November 7, and December 26th!
Last year Pi day was on a Monday, the year before, a Saturday. Back in 2000, Pi day was Tuesday… Check out the math trick that lets you find the day of the week for various dates throughout history!: Check out James Grime’s full explanation of the trick:

In Mathematics Magic and Mystery by Martin Gardner, the author presents an interesting card trick to create a magic square (where all rows and columns add to the same number), using an interesting interactive game with a participant. After playing a game of tic-tac-toe, your friends will be surprised to see they set up the cards in a 3×3 grid summing the number on the cards to 15!
