  • It’s more fun when the problem involves them dying anyway.

    [Introducing KE formula] “Would you rather be hit by a semi truck or a lime scooter? What if the lime scooter is going really fast and the semi truck is just slowly moving through the parking lot?”

    “If I drop [student who is currently on their phone] out of an airplane, ignoring air resistance, how much kinetic energy will they have when they smack into the ground? Is that an “elastic” or “inelastic” collision?”

    Or “spaghettification” when doing gravity. Or “yeah, if a gamma ray burst happened to point at earth, it would wipe out all of human civilization.” Or “if the sun went out we wouldn’t know for about 8 minutes.”

    Physics is phun.

    And you have to traumatize them a little bit for lab safety. I remember my upper div physics lab back in undergrad started with like a full two hours of “these are all the ways you can die in here.” I always make sure to talk about Karen Wetterhahn in my own safety lectures.
















  • Knowledge based fields were historically a “safe space” for queer and disabled people. If you are just super fucking smart and could be a wizard in a programming language, or were a genius physicist, you could get to the point where you were too valuable to fire for being trans or disabled. I may be trans and an unperson in the place I live, but I can do calculus, and there’s no way they can take that away from me.

    There’s an attack on knowledge itself going on right now. A desire by the rich to control information. They want to force us into an unreality where skill and knowledge are meaningless. This hurts people who are socially marginalized, because it takes away one of our few paths for economic survival.

    It goes with the attacks on DEI. What they want is a tool that can replace the need for talent, so that they can select who gets to have jobs. They want all jobs to be Graeber’s “bullshit jobs” so that skill is meaningless and they can allot them out to the people they think “deserve” them.
