Comment Hematite vs Rust (Score 4, Informative) 20

Hematite is one specific type of iron oxide. Rust is a non-technical umbrella term for all iron oxides, and the typical red ones we see in daily life are formed by contact with water and are not hematite. Hematite is a dark charcoal gray and is sometimes formed as a byproduct of iron ore processing or other heat and pressure processes in the ground, where oxygen may be present but not water.

I'd be fine with this. Recently Audible removed a book from my library and essentially told me to kick rocks. I'd listened to it when I first got it, and although I wanted to go back and check something in one of the chapters (which is how I found the book was no longer available), it's not the end of the world: it's just $15 they stole from me.

I'm glad you got to have kids and watch them grow from birth. I never got to do that; I married a gal and the boys were already ten and eleven years old when I entered their life.

Comment Re:Not a bad thing, necessarily (Score 1) 91

I agree. I think a second benefit could be that interested high school (or college) students now get a data source that doesn't change locations from administration to administration. It is mildly frustrating to me that many government websites simply change where things are each year. Worse is when a department goes through the amazingly beneficial operation of name change. /s

Comment Re: "far too small to generate any lift"?? (Score 4, Interesting) 106

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.

Comment Re:Going to embarrass the US (Score 1) 173

A New Yorker reporter was recently deported for reporting on the Columbia student protests. This unfriendly climate will kill tourism in America. Then it will have a ripple effect as future presidents and prime ministers go elsewhere to study, killing America's soft power among elites of other countries. And for what? It's not like legal student visa holders were causing a crime wave.

At least this shows Europe (Anti-tourism is spreading across Europe) a way forward in how to stop tourism
