My driving instructor used to lean across to blow the horn and wave when he saw one of his former students. I noticed that a high proportion of his former students seemed to be pedestrians.
We both used to confuse "left" and "right" too, which sometimes worked out fine.
We don't teach physics students the details of epicycles before covering Newtonian gravity nor do we teach students latin (any more) before learning modern languages like French.
That's very true. The only exception seems to be IPv4 addressing, where people are told about obsolete and confusing classful routing (A, B, and C) before the much more useful modern stuff (/24 etc.).
ProgramErgoSum should go and find someone who grew up in the 60s and ask them if they would have preferred learning about airships and blotting paper, or Saturn Vs and lasers. I know which I would have chosen.
If we mine a shitload of material out of the moon, won't that affect it's gravitational effect on the planet?
Mass of moon: 7 x 10^22 kg
World annual steel production: 1 x 10^12 kg
World annual concrete production: 2 x 10^13 kg
Not an imminent problem to solve!
Argon has already been shown to be "non-noble" many years ago - hell, you can buy Argon compounds from chemical suppliers right now (like Argon difluoride).
I think you mean Xenon difluoride. I can't find any reports of Argon difluoride being produced.
Just try editing a Wikipedia article introduce a deliberate mistake
Maybe something subtle, like poor punctuation?
If "stability" is an aspect of your definition of currency then Turkey and many countries in the former Soviet bloc don't have currencies either.
Turkish lira range over five years: 1.4 - 2.1
Bitcoin range over five days: 450 - 900
It tracks mileage, hard brakes, and driving times - nobody knows the exact formula. Progressive claims a decrease of 7 mph or more in one second is considered a hard brake. Don't bother living in a major city.
Maybe you would be fine in London...
Average traffic speeds for the 12 hours between 07:00 to 19:00 across Central London in Quarter 1 was 8.98 mph compared to the 8.82 mph observed in Quarter 1 last year, a 1.8% increase year-on-year.

Yes since no one smokes these days.
It seems to be reducing faster than people expected.
Most people smoking in 2013 look as if they've come straight from a trailer park or from Thirdworldistan. It's a far cry from Hollywood stars a few generations ago.
The Earth's crust contains about 5x as much Boron as Uranium, but we already use quite a lot of it for other applications and are extracting it at almost seventy times the rate.
However, 80% of extracted Boron is B-11, whereas only 0.7% of naturally occurring Uranium is U-235.
And it's a bill that hardly ever gets used so people pay a great deal of attention to them when they see them. Whether or not people are intimately familiar with them, I don't think drawing a lot of eyes to your counterfeit transactions is very smart idea.
Especially when even genuine $2 bills can get you in trouble.
I'll give it 10 years before some group of liberals manages to force a rule through congress that all new cars must be capable of autonomous navigation.
I think insurance companies will be in the driver's seat (*) in making this happen. Contrast the rates they will offer to a 17-year-old in (a) a traditional car, (b) a car with instrumentation reporting home, or (c) automated car. Aviva's Drive Like a Girl campaign is just the beginning of this shift.
(*) A phrase that will be less connected to daily life 50 years from now.
It can, only problem is last time I checked (a few years ago though) it took about 6 TW of energy to produce solar cells that could deliver that much energy.
Don't you mean TWh? TW is the rate of energy production.
The good news is that the cells last for longer than a month. From your guesstimate figures it seems like they break even remarkably quickly, and then are energy positive for decades.
