See there is the trick, find companies out there that actually TRY to be human sounding instead of just random grouping of letters and numbers. This is usually the first sign that you're more likely to encounter legit yet cheap product. Vevor is... eh kinda easy to remember and their product listing prices look more like what an actual manufacturer would be charging to retailers buying their stock.

More pressure to get results generally gets more results, yes.

And some fraction of those results won't be good ones, true.

BUT - the whole way science is set up is self correcting, so the bad results... just plain don't work. So you won't ever be harmed, by, say, getting the wrong diagnosis from a Theranos machine. Because it just doesn't work. Instead, people will have egg on their faces, get fired, waste money. (hey wait, wasn't Theranos a business side venture not academia? Surely that must make it immune to ... pressure?)

But: more research means more results overall, some fraction of which is good, so, more overall good work out there, more useful stuff for humanity.

Not mentioned elsewhere in this thread: the fact that grad students do much of the actual research work out there. They're motivated, learning, and make the whole process go (and then go on to be the next generation of scientists, both inside and outside of academia). Fewer students directly scales to less research output. Research output, in the exact modern sense of the phrase we're talking about, is why we're not still living in the 1940's. The Unabomber is sad about that. Why are so many slashdotters?

Comment Re:What do you do with all those batteries? (Score 1) 110

You turn them into static batteries that sit there and be backup power for a house. Even if they're real crap and only 50% SoH, that's more than enough capacity for sitting there providing a power reserve. Because it you rally want 100%, you buy two 50%'s and hardly notice the physical size difference, since you're not driving your house around.

Comment IEEE is horribly under-informed (Score 1) 195

The company I work with can easily ramp up satellite production to the scale required. It's one of the reasons I got hired, my extensive manufacturing experience in electronics and solar and power systems pairs perfectly with the requirements.

Perhaps the IEEE should spend some actual time with the companies that already have some of this hardware in orbit, with more going up soon.

Comment Motorola owns the patent (Score 2) 54

A colleague of mine working for Motorola patented encrypted memory sometime in the 2006-2010 timeframe. Maybe Motorola figured out that AMD was violating their patent and negotiated royalties privately with AMD. I don't know; I don't work at Motorola, but if AMD had to suddenly start paying royalties, it makes sense that they'd remove the feature from lower end, lower margin processors.

Stuff falling in is really falling quite a long way. If its path doesn't intersect the event horizon, ie, it "misses" the black hole: it either smacks (really hard) into other stuff down there that's also not quite fallen in, or slingshots back out. The event horizon being comparatively small, a lot of stuff ends up either in a very hot accretion disk around the black hole, or being blown back out in jets or winds.

This is why black holes are the hearts of some of the most energetic astrophysical objects in the universe: powered by stuff almost falling in, and all that gravitational potential energy turning to kinetic energy turning to thermal energy.

Grading on a curve was meant to hide the fact that some teachers couldn't teach, some could, some wouldn't, and others would. It protected the professor at the expense of the students' education.

And it ruins grades as a marker of achievement or ability. From a student's perspective, if I pay for a course, the result should be that my grade reflects the degree to which I've mastered the material, not the variations between the quality of the students and the quality of the instruction. Grading on a curve allows a deadbeat professor and a deadbeat class to essentially turn the class into a credential mill without the necessity of education.

Students can safely assume that courses graded on a curve are staffed by incompetent or lazy professors, taken by lazy or incompetent students, or quite possibly both. When I was in university, this type of grading was used most often in the general education electives, where the professors didn't really care about the students, and the students didn't care about the subject. To adopt the same approach for mainline courses is to transform the entire university from a place of learning into a credentials broker or diploma mill.
