Andrew Mason's latest activity

I haven't read every post, so I may be repeating an observation already mentioned. But if you switch you lose only if you first chose...

If ##a^0\ne 1## then ##a^0\ne -e^{\pi i}## and the beauty of mathematics would be gone. AM

Hmmm. So those green craters on the pizza at the bottom of my fridge could be due to radioactivity?! I thought it was just the usual...

There are other threads that discuss the similarities and differences between thermodynamic entropy Boltzmann entropy and Clausius...

The radius of Jupiter at the equator is 71,500 km and the radius of Io’s orbit is 422,000 km. The radius of Jupiter’s orbit about the...

Bingo. As should have been obvious, it would not have been possible to time an individual transit since that is defined as the period Io...

Whether Earth is moving toward or away from Jupiter is almost immaterial in itself. The orbital period of Io is about 42.5 hours. In...

As Berkeman has pointed out you would need to cancel the marble’s orbital speed first in order for the marble to drop vertically to the...

If the thermodynamic work done by the gas changes the polarization of the gas molecules, that would be taken into account in the change...

How can you determine the gas polarization energy if you aren’t given any information about the polar nature of the gas molecules? AM

You have found an easier way to solve the problem by noticing that ##a=3/2=\gamma##, the adiabatic constant (Cp=3R;Cv=2R). So the...

The use of capital V for volume and voltage is confusing. I will use lower case ##v## for voltage and upper case ##V## for volume. Your...

Just so I am clear on the linkage, the angle of BD to the extension of BC is a fixed 120° and B is free to slide along BC. You are...
