### Re: What-If 0140: Proton Earth, Electron Moon

Maybe a better interpretation of the question would be one where the rest-mass of the Earth and Moon was each converted into an equivalent energy of protons or electrons -- that is, if it's going to take extra energy to pack two electrons close to each other like that, then you have less energy to ...

### Re: What-If 0054: "Drain the Oceans: Part II"

Further subquestion: if earth's water was to be portalled onto Mars in this way, and to have the kinetic energy that it would usually do due to earth's orbit and rotation around the sun, would the additional mass and differing velocities affect Mars' orbit in any tangible way, and to what extent wou...

### Re: 1179: "ISO 8601"

YYYYMMDD certainly makes the most sense for a file name. DD mmm YYYY (e.g. 27 FEB 2013) is a handy format for shorthand dates in shared notes, to avoid confusion if there's a chance those notes might be picked up by either an American or a somebody else. It's also closer to how we talk about dates (...

### Re: What-if 0027: Death Rates

Pet suggestion on this topic: Pull up a clock or stopwatch which displays seconds ticking by, such as this one . Tap a finger of your left hand on the desk with each passing second. That's the death rate we're talking about. Now double that speed. That's the current death rate* (2 per second). Also ...

### Re: 1114: "Metallurgy"

A nickel iron meteorite represents a decent lump of iron in a relatively concentrated and pure form. Of course its far from what we would consider good iron or steel currently. It is, however, considerably purer than most terrestrial iron ores. If you're just starting to work iron, you're going to ...

### Re: 0977: "Map Projections"

I like Mollweide, Robinson, Winkel-Tripel and Kavreyskiy; generally the best straightforward maps. I do see the navigational use of the equirectangular, or even (bleurgh), the Mercator, but dislike the degree of distortion that's introduced. If I was ever to get very drunk and get a tattoo of a worl...

Incidentally, about 10 years ago, I read an opinion piece by one statistician with cancer who said that he found comfort in the statistics - partly, in being able to decipher the statistics of what factors might actually make a difference to his survival chances. Unfortunately, I've been unable to f...

The US handing out 10 million dollars in donation doesn't cause that money to have less of an effect because it is a richer country. Or because it has more people. How much a country donates per capita, or per GDP doesn't really matter at all unless you believe that rich countries have a moral obli...

### Re: Discovery Channel held hostage by human-hating animal lo

The old rule of "say nothing about the dead, unless good" is largely, as I understand it, out of politeness to the grieving relatives and other loved ones.

I still don't feel too shy about saying this guy was nucking futz, however.

The current situation is actuallya lot better than ten years ago, when Rwanda did exactly what you describe, move in, take over, install their own government and start the plunder. At first, it even looked better than mobutu, but in a few years all countries in the region jumped in to get their pie...

### Re: Ground zero "mosque"

Fair comment.

After the July 2007 attacks in London, a few mosques got vandalised, or even firebombed... along with one Sikh temple.

There hasn't been any general proscription on mosques in the UK, though, beyond our generally very restrictive planning laws.

It's not just the denominator, it's the numerator. There were only 15 cases in the control group (who received placebo). As you can see from the abstract, that leaves a fairly wide confidence interval around the true protective effect: Efficacy and safety of a recombinant hepatitis E vaccine in heal...
