Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Accelerometer problem - difficulty understanding my readout
Is the accelerometer aligned with the z axis in the radial direction? If so you'd expect constant $z$ and zero $x$ and $y$. If the wheel was slightly out of true you could get variations in $x$ and/or $y$ at the frequency of revolution.

comment Which areas of physics are related to the act of playing drums?
I wonder if you'll get much out of a physics based approach. Physicists have a tendancy to simplify problems to make them mathematically tractable, and I suspect the factors that make you different from Ginger Baker are exactly the sort of fine detail that will have to be simplified away to make the problems simple enough to solve. By all means have a go, but don't be too surprised if you don't get much out of it.

comment Perfect Ideal Gas Modelization of Air
A homework question? Really? Whether this is a set problem or not I don't know, but it doesn't look like a homework problem in the sense this site usually uses.

comment Any simple reason why Helium in the ground state is diamagnetic?
That's quite a broad question. Have you researched diamagnetism? There must be dozens of easily Googlable article on it.

comment What causes the triplet state in Helium?
The $1s$ triplet to singlet transition is forbidden but it will occur - just rather slowly. Also the transition is only forbidden for emission of a photon. The triplet state can decay in collisions with other atoms, or in the liquid or solid by transferring energy to the lattice.

comment Any simple reason why Helium in the ground state is diamagnetic?
Everything is diamagnetic but in paramagnetic materials the paramagnetism is stronger. So the question is why is helium not paramagnetic?. The answer is that it has no unpaired spins.

comment Walking & Swinging
The mechanics of walking are quite complex. A Google should find you articles on the subject. Basically, swinging the arms in opposition to the legs reduces the torque on the body and therefore makes it twist less.
