Math Links for Week Ending Jul. 27th, 2018

I thought this was a fun experiment. Ride your bike 140 km, measure the length of your ruler's shadow, call your friend (back where you started) to measure their shadow, use some trig and viola, you've just not only shown the earth is spherical but estimated its circumference. That's what @KurtisBaute did. Great for conversations about the power of math (specifically trig).

A pile of videos from Twitter Math Camp last week. First the three Keynotes from @DingleTeach, @JReulbach, and the trio of @GWaddellnvhs, @mathhombre & @Gelada

One thing that is unique (I think) to TMC is that each day there are sets of "My Favourites" presentations. These are 5-10 min presentations from participants on a topic that is usually short and sweet and sometimes may have nothing to do with math but good pedagogy. For example @Nomad_penguin did a great talk on the work she does helping students revise there math work. To me it looked like the editing/revision process that one would see in an english class. You can get her DropBox folder of resources in this area here and watch her My Favourite (below)

The rest of the My Favourites can be found here (including the one I did on the back story behind my viral video) but one of them was from @stoodle on how the #MTBoS community supported him through a tough time. The story of that time was part of a different event and will eventually be aired on the Story Collider but you can watch it here. And if you have ever felt like things were not going your way as a teacher, you might be able to resonate with this.

Another dynamic @Desmos tessellation from @sumdumthum

Okay this one's a little weird.

I found a circle packing on wikipedia, turned it into a tiling of wonky pentagons and septagons, and did a dual transition of that.#mathart https://t.co/jLKOPXtMO4 pic.twitter.com/VB5UIePJVe

This set of @Desmos eyes from @Gelada is cool but would be cooler with a some of them blinking
