Next they'll send plainclothes policemen to people's doors to ask for a glass of water, or to see if there's an unsecured spigot on the outside of the house. And if they find this sort of freely available water, they'll give them a stern talking-to. Because it(*) all starts with kindness to strangers!

The force required scales as the cube of the speed. When you go twice as fast the air has to move twice as fast to get out of the way, and square that for kinetic energy, but you also have to move twice as much air, giving a factor of eight. (On the other hand you only have to do the pushing for half as long, so the *total* work, which is the integral of the force, goes as the square of the speed.)

Yes, it is a shame he died in a tragic car accident, instead of one of those non-tragic fatal accidents.

That's what Israel tried first. Until the 1st intifada, people in the West Bank and Gaza had largely unimpeded access to jobs across the Green Line, in Israel, and their salaries from such jobs constituted an enormous fraction of the economy of those territories.

It's not like Israel wants to impede the flow of goods across the border, even today. Gaza today, unoccupied, is powered by electricity from electric power plants in Israel. But when aluminum is used to make missiles that get shot across the border, preventing aluminum from getting across the border seems pretty tempting. Regardless of the measure's effectiveness.
