Because the waves on the lunar seas are small, while the temperature differences are large, and rapidly reverse every fortnight. Since...

Why do you think that?

You jest but since Lunar regolith is fine dust one could effectively use that. Use solar energy to move regolith to a high plateau, of...

Well - oh my stars & garters! I'm published! (Five maritime-themed short stories of fantastical fiction set in the deep past, present...

A mental model one can use is this, imagine you are standing on a smooth desert plain. It looks flat, very flat. But you are actually...

It reduces the launch mass enormously. The processing might be worked out and automated beforehand. Of course it probably wouldn’t be...

A good candidate for large Lunar batteries might be MIT professor Donald Sadoway’s dirt based liquid metal batteries because they could...

If ever there was a place for stable, consistent nuclear energy the Moon is it.

I believe batteries could work fine for Lunar bases as they work fine now for arctic bases. Obviously each situation has its own...

I think we can both agree on the following: 1. Using any number of methods, it can be shown that ##h=\sqrt{ab}.## 2. If either one of...

We seem to have different perspectives on this thread which is ok. From my perspective, we were discussing Descartes’ problem where the...

I wouldn't put it quite that way. Starting with ##h^2=ab,## which we assume to be known, we can rewrite it in two ways: $$\begin{align}...

In the case I just mentioned, neither ##a## or ##b## are unit length except in the case where the semi-circle is bisected. Here, ##a##...

Note that if ##h## has unit length, ##a## and ##b## are reciprocals.

The word philosophy literally means love of wisdom. In Plato's time, the distinction between a mathematician and a philosopher was not...
