congratulations!

Guess how many of my teachers are using resubmissions? Count raised hands.

Here is a very useful video if you want your students to test whether energy in an isolated system is constant. Simple to recreate but very elegant. Enjoy. mediaplayer.pearsoncmg.com/assets/_frames… #iteachphysics #modphysics

I posted a video yesterday to figure out that the energy of an isolated system is constant. In this case it was just mechanical. But if you take small marble, a longer track and make it U-shape you can find how much mechanical energy is converted to internal. #iteachphysics

mediaplayer.pearsoncmg.com/assets/_frames… This is our classic ISLE two-in one application experiment: use the two experiments to determine the coefficient of kinetic friction between the table and box. Students learn to revise models. #iteachphysics #modphysics

If you are using College Physics: Explore and Apply and plan to teach Nuclear Physics chapter (29), please send me an e-mail to get three corrected pages in that chapter, they are fixed in the e-book, [email protected] #iteachphysics

Balancing a penny on a coat hanger and spinning it - great example of circular motion! How she gets it to stay on there while it slows down is beyond me.

A cool greeting card for the holidays. The phenomena involved are surface tension, buoyancy, reflection, refraction and LEDs. Happy holidays to all! #Ilovephysics

If you want to change your worldview, read “Sapiens” by Yuval Noah Harari. This is an amazing book.

An article about our recent ISLE-related project

How do we attract women to physics? The main step is to change the way we teach, create a community in our classrooms, remove competition, let improve work without punishment and lots more- will say later.

In the time of political turmoil that we are facing now, what do focus on while teaching physics? Education is the only solution to climate change disaster. Forget cool videos and other stuff, focus on making students independent thinkers #isle physics

I wonder how people can tweet about life minutia today. We should be screaming about racism, deaths of innocent children and total brainwashing of our citizens. Education is our only hope. Making people who can think on their own. #islephysics

Einstein: Teachers waste time asking questions about what a pupil does not know instead of what the pupil does know and is interested in.
