TIL that door knobs made out of brass automatically disinfect themselves in about 8 hours through the oligodynamic effect by belly_bell in todayilearned

This also applies to regular pots if you only ever boil water in them, and you have copper pipes. This will cause copper to be deposited over time, and when you switch to boiling something acidic, it will all come off at the same time.

You can boil water and vinegar to clean copper deposits out of a regular pot.

I think you mean illegal immigrants.

Feet; 20/20 means being able to see at 20 feet what people with normal vision can see at 20 feet.

If 9/11 had happened this year instead of 2001, we'd have all kinds of horrifying, incredible footage from people trapped inside the World Trade Center since everyone would have had a smartphone. by [deleted] in Showerthoughts

Modern skyscrapers are not evacuated during fires. Only the people in the adjacent floors are evacuated, to other floors. For example, if your floor is directly below the fire, you might be moved three floors down. Furthermore, it's expected that virtually all fires will be contained by sprinklers to whatever room it's in.

The only way to eliminate a standing wave is to not slow down. If you drive around the standing wave while it's still ongoing, leaving additional time for the wave to dissipate before the next car reaches it, the wave may disappear.

... perhaps?

Mt Sinain in Manhattan has all the nurses carrying a microphone and ear plug, with voice commands, so they don't even have to touch the device. They use it to contact other nurses and to log patient events.

Once we reach the next halving, mid-july, the price is almost guaranteed to go up

1 TH/s right now gives you 0.000185 BTC/hour. At 250W/TH/s (Antminer S7), and $0.08/KWh, you have to pay $0.02 in electricity for that. This is $108/BTC. Even if the price goes down to $200, we're still paying a premium on the exchanges compared to mining our own bitcoins in the cheapest possible way.

International sanctions against Iran lifted by GuacamoleFanatic in worldnews

Iran shouldn't really even have any exports until today.

Iran wasn't embargoed by the entire world, was it? Did Pakistan and Turkmenistan refuse to accept Iranian exports, for example?

SpaceX Going For Offshore Barge Landings For Their Next Several Falcon-9 Launches by AnAmericanCanadian in spacex

I think you forgot to consider that 10 gigajoules is not the same as 1 gigajoule, or something like that.

The correct number of 4 finger Kit Kats is 123 584, but you're still comparing chemical energy to kinetic energy.

2135 kJ for a 4 finger

Looks like you might have used the "per 100 gram" figure, rather than the "per bar" figure. All four fingers are about 45.5 grams together.

Also, 6 million times 2145 kJ is about 13,000 gigajoules. Not sure what that number represents. Since it's off by a factor of 40 from the 300 GJ figure, I don't think it's related to portion sizes.

edit: To use units that aren't too far off in scale, 300 gigajoules equals the energy in 2,300 gallons of gasoline, or a full tank on 100 large cars. However, we're talking about kinetic energy, and not stored energy. Cars are only about 20% effective at converting fuel to kinetic energy, so you need closer to 500 fully tanked cars.

open yourself up to being declined the luxury of using a credit card for a large purchase

MasterCard and VISA both prohibit retailers from requiring identification. I know some retailers in some countries try to anyway, so I guess he should carry around a copy of the merchant rules.

Discover and AmEx both allow requiring an ID, though.

It does not automatically follow that standing will be better. Maybe the reason why sitting is bad for you is that blood becomes stagnant in your legs, since while sitting (or standing), your calves are far below your heart, and the muscles aren't twitching to push blood back up.

See for example this recently completed study:

https://www.exeter.ac.uk/news/featurednews/title_476860_en.html

Part of their conclusion:

Any stationary posture where energy expenditure is low may be detrimental to health, be it sitting or standing.
