Tire Pressure & The Polar Vortex in Jupyter Python
05 February 2023
I had low tire pressure yesterday due to the polar vortex, so I added
additional air to my tires to about 34PSI at 22F, today it is much warmer at
nearly 50F and the PSI went up more than I expected. Also the PSI doesn’t seem
to change as much from Spring to Summer, when the weather can swing up more
than 20 degrees from night to day. I decided to write some python to try to
figure this whole thing out using the Ideal Gas Law. Also no attempt was made
to account for the weight of the car, and how that adds pressure to tire.
Rise of Gru - Waterfall to Steam Door Physics
06 July 2022
“Minions: The Rise of Gru” was pretty good, and tells the origin
story of Gru and his formative years. That’s all well and good, but the
waterfall trap scene was the most interesting piece of the movie to me.
The movie opens with some villains attempting to steal this mystical
artifact from a temple. In order to get into the temple the villain must
reorient these dragons which blow fire to clear away the falling water
by turning it to steam. Is this even possible, and if so how much heat
would it take, and why wouldn’t the opener be singed by the overwhelming
temperatures?
