You are in the 35% federal tax bracket, but the federal withholding on your commissions is probably 22%. That means you have about $10,000 too little federal withholding just from that. You need to either make estimated tax payments or increase the withholding on your other income to compensate for the underwithholding on your commissions. (You could ask your payroll department if there's a way to increase withholding on your commissions, but usually there isn't.)

This is correct. To an outside observer (us), it takes a photon about 8 minutes to travel from the sun to the earth. To the photon itself, it is instantaneous.

One of the ways that it was determined that certain neutrinos have mass is that there is a nonzero probability of them mutating while they travel between the sun and the earth. If they had zero mass, they would travel at the speed of light, and there would be no passage of time during which they could mutate.

At least four bits.

But the tax savings from deducting an expense is at the marginal rate, not the average rate.

It is accepted as a separator by some programming languages, because comma, period, and space already have other meanings. I didn't know there are places where it is used naturally.
