Comment Re: Just what the Moon always wanted (Score 1) 97

Actually, it is pretty much accepted from what I understand that the Moon had several influences on the rise and development of life on this planet, from (among others) stabilizing our spin, to moderating the seasons, deflection of large asteroids, and even to the development of optic cones in addition to rods (or rods in addition to cones, I forget which), etc.

I think that it was Asimov that pointed out that our Moon follows a fully concave path around the Sun, i.e. never travels backwards, and in his opinion that defined us (for him) as a dual-planet system.

In order to account for binary systems, I generally look at the central axis of rotation - if it's inside one of the bodies, that body is the 'primary' - IE a planet, sun, whatever. If it's outside, then it's a double system.

So if the moon were located about 20% further from Earth, then you would consider the Earth-Moon system a binary system?

Hi neighbor! I've been to Aqaba though I haven't dived there. You should know that as an Israeli, I'm very happy to see Jordan building a nuclear power plant. We (humans) need _clean_ energy, even if it is more expensive than burning carbon. And anything that advances the Jordanian standard of living is good for the entire area, especially considering what is happening on Jordan's northern and eastern borders right now.

Or at least their certs removed from valid CA Root lists that, for example, Mozilla uses. If not, why not? A trust has been breached.

The truth is that users have no way of knowing which of the tens of certificates included in the browser to leave and which to remove. This Super User question remains without a satisfactory answer, even as browser cert issues pile up almost monthly:

Comment Re:Low gravity (Re:Stupid.) (Score 1) 124

The low gravity of Moon would allow the elderly (and other infirm) to remain mobile for many years after they would've become wheelchair-bound on Earth.

In order to enjoy 0.3 g on the Moon, you need to suffer 3+g for a good ten minutes leaving Earth. I'm not sure that the elderly or infirm will stand for that.

The Saturn V's actually were one of the slowest-accelerating human-rated craft to ever launch, and they hit a peak of 40 m/s^2, about 4 g, at MECO 1:

The odds of another tourist stealing your camera when you ask them to take a picture is pretty much 0%.
The odds of a someone (especially a poor local) who asks YOU if you would them to take a picture of you
stealing your camerais pretty much 100%.

My country (Israel) is full of tourists, and when I see them taking turns photographing each other I offer to photograph the group. I've never stolen a camera, and others do as I do without stealling cameras. I suppose that your advice might be culture-dependent.

This is the same advice I give my kids. If you get lost, don't
wait for someone to approach you, instead walk up to the first person you see and ask for help. Most people
are normal law abiding citizens, if you play the odds and pick someone randomly then your chances of getting
a criminal are very small. If instead you let them approach you then they are picking you which makes the
odds of them being a criminal considerably higher.

That is good advice for kids, and I will in fact start giving it.
