  • It’s a US label and the percents are % of recommended daily intake. So that’s 3% of your daily recommended carbohydrate intake, 6% of your daily recommended intake of sugar, and 12% of your daily recommended intake of “added” sugar. The recommendation is something like, no more than half of your carbs should come from sugar, and no more than half of those should be added during manufacturing (i.e. most of your sugar intake should be from fresh fruit, etc.). So the numbers do line up.

    I think that might be an underestimate. Mass and energy should be conserved, so if the entire black hole evaporates the total energy output should be E = mc2. An A4 page has a mass of 6.25g. c is the speed of light, 299,792,458m/s.

    0.00625kg * (299,792,458m/s)2 = 561,721,986,710,511.025J

    The explosion of 1 metric ton (1000kg) of TNT is considered to be equivalent to 4,184 Joules. So 100KT = 418,400,000J. That’s not close at all, we’re gonna need more TNT:

    561,721,986,710,511.025J / 4,184J/ton of TNT = ~134,254,776,938 tons of TNT.

    Rounding off to significant figures, we’re looking at 134 gigatons of TNT. For comparison, the Tsar Bomba, the most powerful nuclear weapon ever tested, had a yield of 50-58 megatons. That’s somewhere in the neighborhood of 2,500 Tsar Bombas!

    Maybe this paper folding experiment should be performed away from anything that might be damaged by the explosion. Like, uh, inhabited continents.

    As pointed out below, I biffed the joules-per-ton-of-TNT thing, sorry!

    I liked healing in MMOs when all I had to do was click healthbars to fill them up. Other people did all the hard work of actually fighting monsters, and I got loot!

    Now MMOs want to make healers “interesting” so that more people will play them, and this means I have to contend with actual mechanics and sometimes even deal damage. Sorry, my brain does not multitask, I’m simply not cut out for this anymore. :P




  • The last time I was handing out candy at my old neighborhood, kids would ring the doorbell but then they’d just stand there and stare at me until I handed them candy. You’re supposed to say “trick or treat”!

    Now I live in an apartment, so I don’t get trick-or-treaters. (I have candy just in case, but nobody ever knocks.) My roommate went to hang out with his sister and hand out candy at her place, and apparently their neighborhood has decreed that trick-or-treating ends at 7 sharp now so that nobody is out after dark? I don’t get it. I thought staying out late (and, for teens, potentially unsupervised) was part of the fun!
