When you teach mechanics ... @DrSam_George

Another one for the Newton's laws bag

I've studied fluid mechanics. I know what lift is. But I really don't like winged things that don't flap. They just look wrong. Like it shouldn't work should it? Surely that's a bug? Can we all agree to move over to ornithopters please?

Good to know they've found a way to produce light without using protons on neutrons. Presumably it works on some sort of neutron scintillation?

I did a 5 minute diversion in my lesson yesterday about Fermat's last theorem, no idea it was the anniversary of the proof today!

Physics: I couldn't find this already so I made a displacement-energy graph for the vertical mass spring system. It's quite a lot different from the pendulum one desmos.com/calculator/wam…

It's not reasonable how funny this game is

There's actually something in this for Physics teachers about significant figures and measurement uncertainty. I always find it difficult to tease out the difference between 4, 4.0 and 4.00.

Marie Curie's notebook. Looks like she was trying to work out the voltage required to make the magnetic field strong enough for....some particle deflection? Alpha maybe?

#Physics teachers, what are your go to demonstrations on introducing the topics of photons and quantisation?
