How much of a dose do you actually get from the scans?
The best numbers I can find seem to point to something in the 0.015 μSv to 0.88 μSv range. At cruising altitude, you get 0.04 μSv per minute from cosmic radiation.
I don't think the radiation from these machines should be the biggest concern.
It's not germane to this discussion. The previous poster only brought it up to draw parallels between a straight person being for allowing gay marriage and a non-smoker being for legalization.
I've found the more rural gas stations stock 100% gasoline. I assume it's because the older engines in farm and sporting equipment don't take kindly to E85 (different valve timing needed, it's rough on old seals, etc).
The teacher has had students over before, and unlocks his/her home by grabbing the key out of the fake rock sitting on the doorstep. The student uses that key and wrote something obscene with the fridge magnets.
It's not quite breaking and entering, but it's more than trespassing.
If she had her own mail server, it's probably fair to assume she could have set it up as her outbound mail server and to use TLS of some sort when connecting to it.
Speaking of burning man... I missed the ticket sales because my dumbass didn't check the "register try to buy tickets" option on my burner profile. Anyone have one to spare?
I've heard east coast (US) coal is dirtier than west coast (US) coal, particularly in sulfides. The acid rain fix known as the Clean Air Act of 1990 was heavily lobbied by the east coast coal producers and bears some marks to show for it. Burning so called "Clean Coal" has to do with how much gross weight of sulfur you pull out of the coal, which makes sense for coal heavy in sulfides, but less so for west coast fuel. As it stands, to burn west coast coal in the US requires the addition of sulfides to the coal so it can then be pulled back out.
As for other impurities... there are a lot of radioactive crap in coal that is aerosolized during the combustion process. The most notable of these is uranium, which is carried away with the rest of the fly ash. There's a "shadow" around coal smoke stacks where such fly ash ends up accumulating. If it makes it into the water table or onto arable land that is used to grow crops, BAM, you've irradiated a small chunk of your population.
Depending on the source of the coal, there are various other heavy metals that can end up in your fly ash.
Yep. Look what happens every time a bitcoin bank folds. Everyone who had coins in that bank rather than in their own wallet suddenly loses every coin they have.
There are some strange regulations on savings accounts in the US. You're only allowed a set number of transactions on them per month. Checking accounts don't have these limits.
The whole Manifold series is interesting. Each Manifold book stands in its own universe, but uses the same cast of characters with a different set of answers to Fermi.
I got on a Baxter kick after powering through his Long Earth books (ostensibly coauthored with Terry Pratchett, though Pratchett's fingerprints are rather non-existent after first book). As long as you're ok with Baxter's strong dislike of organized religion, he seems to be one of the better modern science fiction writers.
