It comes with a C compiler, tcc, and vi! What else could you possibly need, right?
"The growing consensus is that the Milky Way has a central bar with two main arms, called the Perseus Arm, which passes with a few kiloparsecs of the Sun, and the Scutum-Centaurus Arm. (The other arms are now thought to be minor structures made up largely of gas.)"
As a resident of the Orion Spur, I resent that statement.
This craft doesn't actually have a sail. It gets blown around by the wind, hopefully for a while before getting stuck on some shoreline.
In the graphic showing the concept for the final vehicle, the train appears to use jet engines. Is this really how you would do it? I thought that jets were pretty much dreadfully inefficient unless operated at altitude.
Sure, I can think of plenty. "Imminent eruption of Yellowstone Caldera is predicted: ash set to spread over large area and disrupt food supplies." "Russia just launched its nukes: remain inside and get your fire extinguishers ready." "Cubs win world series: stay on the lookout for flying pigs." Okay, maybe not that last one.
Besides, I think that is actually the point of having a separate chip. If you use a different channel for these alerts, AND if the system is implemented well, you could have the electric grid and phone networks wiped out and all the cell phones with battery power left will still get the alerts.
Introductory quantum mechanics can be taught at the high-school level.
Really? I took E&M as a college sophomore, and the last couple weeks of the course were an intro to quantum mechanics. It was difficult. Even if you could stretch that couple weeks over a much longer period of time, I doubt that any high school would attempt it.
Feynman wrote that book "QED," which was for a general audience and is sort of an intro to quantum mechanics, but he had to take a very unusual approach in order to pull it off (and of course you don't get to learn any of the math).
IF I HAD A MINE SHAFT, I don't think I would just abandon it. There's got to be a better way. -- Jack Handley, The New Mexican, 1988.
