Do bad knees or plantar fasciitis carry over into zombiehood?

I wonder how many PF members have read anything from Matthew Watkins' "Secrets of Creation" trilogy, where he attempts to present the whole topic in a totally "rhetorical" style with absolutely no equations. Can someone actually start from zero and then take some profit from these books?

Thank you! 😊

First attempt using Gemini --- there are tweaks that could be made but...

The second picture could be a bronc in a rodeo launching the rider into a parabola.

Another example of analogous devices embodying related principles, like the the ones posted above...

I am no expert, and I came across the concept of "formalization of proof" only very recently, but... There is a process called "formalization" of a proof that renders it into a very rigourous, symbolic, machine-processable form. Once that is done, another algorithm can verify whether the proof...

If we think of this as a collision, (a) and (b) together don't mean that momentum isn't transferred and conserved. In abstract terms, is this not equivalent to a collision between two steel rods, or quartz rods, or whatever? In the pump case, the post-collision separation (rebound) might show up...

I wouldn't be too sure. Maybe you were on the right track to start with... OR... maybe a moment of low enough positive pressure that the deadweight can overcome it and reopen the valve? And that moment will come when the K.E. of the moving water (plus some energy stored as compressed air) has...

I decided to start with the simplest toy problem and work it up step by step into a full ram pump simulation. Gemini gives me this diff. eqn. for the simple problem I have sketched below. Does it look right? ##\frac{dQ}{dt} = \frac{\pi d^2}{4\sqrt{X^2+Y^2}} \left( \frac{P}{\rho} + gY \right) -...

I am still not sure whether finite non-zero compressibility is a key feature, or merely a secondary / tertiary modifying effect. If we compare two simulations, one with finite and realistic compressibility and the other with incompressible fluid, and if we include the air chamber, will there be...

Rather long, but well worth watching.
