comment How do HUD optics create readable text so close to the eye?
I think I'm probably going to need a diagram for this. I understand how optics can be used to make close things appear far away. I guess the real question is how do you do that AND see the real world behind that image? Is it just because the lensed image is only displayed on a relatively sparse grid of pixels, and you can see between them, or does the HUD optics actually incorporate the background image?

comment Difference between nautical and terrestrial miles
This seems like a primo question for the History of science and mathematics site proposal on Area51.

comment Why can't we see gases?
Ah, ok. However, even the one second from the left looks a little more opaque than the other three (it's harder to see the back of the ring).

The $N_2O_2$ appears to be more white than colourless in that image.

comment Why can't we see gases?
@Bernhard: It kind of is the explanation - if air (and water) were mostly opaque in the visible light spectrum, there would have been no reason to evolve visual senses in that spectrum. We might have evolved "sight" in a different part of the EM spectrum though.

comment How is the Earth heated by a Full Moon?
How does $\frac{95.8mW}{1000W}=10438$?? Presumably that's supposed to be inverted?

"on" in the question title should probably be "in".

comment Why is superdeterminism generally regarded as a joke?
@Dokkat: Randomness is basically just a lack of pattern. What makes you say that it requires a "will from outside"? Why would it have that requirement more than any other pattern, or lack of pattern, would?

comment Is the total energy of earth changing with time?
@DavidH: hrmm. Yeah, you're right, I was misunderstanding the definition of equilibrium. Is there a word for when the earth system has no net heat exchange with the rest of the universe? Something along the lines dynamic equlibrium (in chemistry)?
