What's the alternative, though? Removable panels will be more expensive, and troublesome in various ways. Drywall is not too bad to deal with. And 99% of the wall surface doesn't need to be opened for a -long- time.

Yah. He didn't write the Feynman Lectures on Physics. He just came up with the unique arguments in them and gave the lectures at Caltech; it fell to Leighton and Sands to do most of the work of knitting it into a cohesive, coherent b

Big revenue + small margins in a stable business, IMO, is a massive liability for the bottom line; any downturn in business and that becomes big revenue + big losses. Even if cloud is making money, it can wipe a lot of that out. From the p

What radiators look like is foil or sheet covering fluid loops to spread the heat, control the color, and add surface area. They are usually white, because things in a spacecraft are not hot enough to glow in visible light and you'd ra
