Just Some Items I Find Interesting

I've been collecting these as I find'em:

The mass of all asteroids in the asteroid belt between Mars and Jupiter is equal to about 3 percent of the Moon's mass.

A spaceship could travel outward through the asteroid belt likely without seeing any asteroids at all.

The magnet strength in MRI machines ranges from 0.5 - 3.0 T (Tesla).

The Earth's magnetic field on the surface ranges from 22 and 67 μT (microteslas). That's a ratio (MRI/Earth) of about 50,000.

Your hat size is the circumference of your head, in inches, measured just above the ears and across your forehead, divided by π. In other words, it's the diameter of your head for that ring. Not sure what metric countries do. Not gonna look it up now.

Americans spent $4 B on pet insurance last year.

Last summer the water temperatures off Miami reached as high as 101°F (38.3°C).

Medicare [US medical care for seniors] loses $60 billion a year to fraud, errors and abuse. OMG.

It used to be that humans emit 100-200 times more CO2 than do volcanoes [Gerlach 2011], but recently that range has been revised to 40-100. Still a lot more. [Don't know the paper for the latter range yet, but will try to find it, as deniers frequently say something like one volcano emits more CO2 than humans have in their entire history.

{Yes, I had a post up before this one about a very dumb headline error made by The Telegraph, but I accidentally deleted the text and am not going to rewrite it. It's about the third file I've botched in two weeks, saving a short file on top of a large one, etc. One file was about 5,000 words and represented e^several hours of writing. I hope these are just coincidences and I'm not entering into dementia.}

So far, the smart money is on ignorance for the destruction.
