New #DIY #Science video - building a very simple (but working) ribbon microphone.

For one version I use #LEGO, aluminum foil, and hard drive magnets.



Not directly from #MacGyver - but related. BTW - this website is great for recording and analyzing simple sounds

I'm starting to put together my presentation for Star Wars physics lecture. It's difficult to pick just a subset of all of my stuff - but I think this is going to be good. 2/ Here is my tentative list. Check me. Are any of these dumb? Am I missing something great?

Oh, everyone is going crazy over this Simone Biles tumbling pass. You need some #physics physics to go with it? I got you covered.

1/ Here is the physics of a flip with a twist, it's about angular momentum.

THREAD. In honor of the #Apollo50th anniversary of the moon landing, here is a thread of #physics posts related to space travel. @nasa @esaoperations @ESA_History 1/ I will start with my #physics #estimation - what would be like to ride a bike to the moon? How long would it take? How many sandwiches would you need to eat? More homework included.

Yesterday in #physics class, I had to have the discussion about learning vs. telling the answer. I got to use my favorite Karate Kid analogy - "wax on, wax off" to emphasize that sometimes you have to do tedious things to learn.

wired.com/2013/10/tellin… 2/ What happens when you just tell students answers? They have trouble learning complicated concepts. Personally, I love this (older) video showing students trying to explain the phases of the moon and the cause of seasons. It's great.

MEGA THREAD. Happy #PiDay to everyone.

Let's start with the simplest calculation of Pi - the ratio of circumference to diameter for round objects. wired.com/2014/03/calcul… 2/ If you want to do this calculation of Pi, just find a bunch of circular objects of different size. Use a string to wrap around and measure the circumference and then measure the diameter. Plot C vs. d - the slope is PI.

THREAD. Need some #physics ideas to go along with your holiday presents? I have you covered.

Here is my list of some cool physics experiments I have done with toys and stuff. 2/ How fast are #Nerf darts? Video analysis included.

THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large. 2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…

14/ Follow up - if your science class isn't confusing, then something isn't right wired.com/2016/04/scienc… 15/ Now for some advice geared more towards faculty. I will start with the big one - we should be moving past the traditional lecture. There is more that we can do wired.com/2017/05/the-me…

THREAD. For many it is the near the start of the fall semester. Here I will share my teaching and learning posts. Some of these are for faculty and some are for students. 2/ I'll start with posts that just deal with students. My first recommendation - ditch that scientific calculator. It's overpriced and not nearly as good as python wired.com/story/ditch-th…

THREAD. Here are some of my favorite #MacGyver hacks - most of them you can easily do yourself. These could also make great projects for kids. 2. For each hack, I will give two scores. Difficulty (D) from 0-10. A 0 difficulty means you already did it and a 10 means you will probably mess up a couple of times.

The other score: Equipment (E) from 0-10. 0 means no equipment 10 is specialized stuff.
