I work to help my students see how physics changes the way they see the world.

@RobSpencer1 Could you use an online strobe website like https://t.co/16lBXeG0is

[John Burk @occam98]

@RobSpencer1 I think you could build a simple react native app to do this. Here's what I was able to put together with https://t.co/PoAqyAO2MN in a few minutes: https://t.co/IWCWG5RgFc.

@joshgiesbrecht It worked! Thanks!

[John Burk @occam98]

@joshgiesbrecht Oh, that makes me even more curious to see what 6th grade math looks like in Canada…

[John Burk @occam98]

@joshgiesbrecht Any chance you’d be willing to share those? I have a 6th grader and am curious what standards get covered in other classrooms…

It's been a long time in the pipeline...Python in Tychos! Now you can code in either Python or continue to write your simulations using MathJs. Python is the new default, but just change it in the Settings tab.

Python in Tychos...here is the new Language Reference Docs: https://t.co/ZOf88GpoDL

@bennettscience How about @gcschmit’s Polar Bears around an Ice Hole: https://t.co/ly8SfStbGj

The sign on top of this convenience store fridge selling beer reads, "Beer Therapy." Another sign of the triumph of the therapeutic.

In a video message, Ukrainian President Volodymyr Zelenskyy called for peace talks with Russia to be “meaningful, fair and without delay” to stop the invasion of his country.

Previous rounds of talks have so far been unsuccessful. https://t.co/mwgK9sIulL

@Jennifer_Manly @ShriramKMurthi OMG - yes. I lose much time to this. Other major headache is lack of partial credit on digital exams. No way to download Ss responses (they'll email csv if asked), AND no way to upload partial credit scores. Yields lots of student panic and email.

@TRegPhysics Vectors—2+2 can be anything between 0 and 4.

[John Burk @occam98]

@dandersod Have you seen 3blue1brown’s latest? https://t.co/p23QzmWz0h very related to what you are doing and probably accessible to students.

[John Burk @occam98]

@thgmansur Hi, sorry. I gave all of these away years ago.

[John Burk @occam98]

I still have ~10 copies of the 7th edition of PSSC Physics, which is an amazing textbook you want to have in your collection. It can be yours for $4.19 in postage. #Iteachphysics

@pricepd @TychosTeam It’s working fine for me when I try to login…

[John Burk @occam98]

@metabase do you support two-factor authentication?

[John Burk @occam98]

@brianwfrank @DeltaGPhys Thanks Brian! I love this video.

[John Burk @occam98]

If a sphere is sliding and rolling across a level track, Ff acts at the point of contact and is opposite the motion of the sphere. If I take the axis of rotation as the pt of contact, then Ff, Fn, and Fg all act through the axis, so the net torque is zero. So how does L change?

[John Burk @occam98]

@DeltaGPhys @brianwfrank Thanks Josh!

[John Burk @occam98]

@BriannoColler Thanks so much! Super helpful!
