With all of this talk about datacenters in space, and the pushback along the lines of thermal control, it is worth reviewing what the physics says. Objects in space primarily lose heat through radiative heat loss, also known as Stefan-Boltzmann radiation. This is governed by the…
Cherenkov radiation is a form of energy that we can perceive as a blue glow emitted when the electrically charged particles that compose atoms.
Drinking a beer a night for a year is a lot less harmful than drinking 365 at once. Radiation is similar.
Bandits are plundering metal from old shipwrecks, in search, it seems for the world's rarest, and strangest, metal.

Post-nuclear steel is a little bit radioactive, so for some specialist jobs we need to find a source of steel from before the bomb
Antennas allow information to be transferred to distant locations. In the second part of this Antenna Basics series, you will learn more about the physics of how antennas work.
Most of us try to avoid radiation, but not Andrew Walker, who collects radioactive objects. The surprising part? These items can be found in a variety of common places.
