Math Links for Week Ending Apr 28, 2023

Featured Links 

This week is the OAME2023 conference. Since 2003 I have presented at every conference except 2005. Most years I present entirely new topics though there are some repeats. This year I did a new session on Equation Strips and re did my session on Desmos Challenge Creator plus I updated my 2006 presentation on Math Podcasts for the virtual conference. Most of the slide decks can be found below:

OAME2023 - Now that there are some expectations about circles in the MTH1W curriculum, I'm happy to see people talking about them. Check out some of @MSBJacobs' slides for these and other topics

It’s been a while since i’ve worked with circle theorems and @msbjacobs gave us those, triangle properties and more with physical and @geogebra manipulatives https://t.co/OhrHar16SQ#MathChat #iTeachMath #MTBoS pic.twitter.com/sO1NhFHCxe

Seeing as we just mentioned circle theorems, above, it is fitting that @Mathigon shared this activity dealing with how Eratosthenes was able to measure the circumference of the earth using some of these ideas.

Happy #EarthDay! More than 2000 years ago, the Greek mathematician Eratosthenes found a way to measure the radius of Earth just using shadows, angles, and simple geometry. Learn more at https://t.co/eXCWnJgq9B pic.twitter.com/lh82JtNusD

Another point that I agree with @Howie_Hua on, use some common sense. Just because things look complex, they aren't.

If you are not sure what Midjourney is, it is an AI where you can put topics in and it will try to create images based on your topics. In this case, it's the interpretation of these mathematical concepts that produce these awesome images. Be sure to look at the whole thread.

I described some of the most beautiful and famous mathematical theorems to Midjourney.

Here is how it imagined them:
