I have a moderate hatred for most entry-level physics textbooks, which manage to pad about 100 pages' worth of information into a thousand-page tome full of glossy photographs in order to justify the $100+ price tag. So if there are any good free texts that would be great.
How about "it looks REASONABLY GOOD" or "it looks ABOUT LIKE YOU MIGHT EXPECT"?
I suppose, on the upside, that once you had this thing in space it could stay there -- a nuclear reactor plus plasma rocket which could just shuffle back and forth between Earth orbit and Mars/Jupiter/wherever, refuelling at every Earth stop.
I wonder if a reflective helmet would be a decent countermeasure (or, dare I say it, a tinfoil hat?)
Oh, certainly. I've never found a case where there's genuine ambiguity, it's just that there's a certain part of my brain which takes delight in pointing out all the potential flaws in everything I read. It's much harder to concentrate on the test when half my brain is busy visualizing what four hundred Captain Picards would look like marching down my street.
Is there some kind of competition I don't know about to mention the words "straw man" in as many threads as possible? It seems to pop up in just about every thread, along with the words "correlation does not equal causation".
"What comes next in this sequence? 1,4,9,16,25,"
Sure, the answer might be 36, but then again maybe we're looking at some subtler sequence of numbers than that. Maybe it's "the number of bald men who walked past my house every hour since 5am". Maybe the next number is 345 due to the annual Patrick Stewart Lookalike Parade. Who knows?
This, of course, doesn't make life any easier for anyone, except the jerks who already use cards for everything (aka the jerks I always get stuck behind in line while I wait for their little receipt to print and get signed).
Also, because people upvoted it before taking time to read it carefully and think about whether the advice was really valuable?
"Introduction to Proofs and the Mathematical Vernacular" -- this is actually pretty good, and I kinda wish I'd had a copy of it at the start of my university mathematical education, if only to teach me what the hell a "Lemma" was, exactly. It's also fun to read.
"21st Century Physics Flexbook" -- very odd. Admittedly intended as a K-12 textbook rather than a university-level textbook, but not much of a way to learn physics even for the kids. Virtually no mathematics whatsoever, let alone calculus. A random grab-bag of topics from "gravitation" (with an attempt to explain relativity which would be more confusing than enlightening) to "nanoscience" and "biomedical imaging". Basic mechanics finally comes in at the end as an afterthought. Not recommended to anyone.
