AI Thread Summary
When a basketball and a baseball are dropped simultaneously, the basketball rebounds and collides with the baseball, which is held above it. The basketball, being three to four times heavier, will rebound with a surprising speed that can propel the baseball upwards. This physics puzzle highlights the principles of momentum and energy transfer during collisions. Participants are cautioned against performing the experiment indoors due to potential damage. The outcome of the rebound speed is unexpected and can lead to interesting discussions about physics concepts.

This is the Puzzle

Hold a basketball in one hand, chest high. Hold a baseball in the other hand about two inches above the basketball. Drop them simultaneously onto a hard floor. The basketball will rebound and collide with the baseball above it. Estimate the rebound speed of the baseball? Assume that the basketball is three to four times heavier than the baseball.
The result will surprise you. Don't do this in the house!

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Highway: Deriving speed from Doppler shift'

I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
