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.

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.

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.
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?

A contractor with zero experience got a $34.5 million contract to supply the VA with masks and other medical supplies. He flew around the country on a private jet trying to track everything down. He ultimately did not deliver a single mask to the VA. propub.li/30ikdHD
What independent schools are moving to pass/fail for the rest of the semester now that you are going to virtual school?
Who said blogs are dead? I posed this quantumprogress.wordpress.co… less than 10 minutes ago, and got 3 great suggestions! Thanks! All it took to bring blogging back was to confine the whole world to their homes….
What would be great is if the work just went to some sort of virtual class whiteboard, and each post was initially titled just by student name and time stamp, and organized by student, so it’s super easy for me students to take “snapshots” of work in progress, 3/
