The Banach-Tarski paradox is fine with me: Not all subsets of the real line or R^n for the set of real numbers R and positive integer n are measurable. Yes, the usual example of a non-measurable set uses the axiom of choice. The sets in t

Uh, depends on the size of the hay loft! The barn with hay loft I saw growing up seems to have been good for the whole winter, and that was on a dairy farm. Another approach on such a farm was a silo , a tall cylinder.

"TFA" means WHAT the heck? I just followed the URL given in this thread and commented on what I saw in LOTS, dozens, of pictures and compared with some of what I know about how the US has solved the problem of gathering and safely

WOW. Thanks. The images I saw showed the houses as nearly all log cabins where the logs were not painted, and I didn't see anything that looked like electric power lines. Can get Internet from just cell phones although of course n

WOW! Follow the link of the OP and see a lot of colorful Romanian culture ! So, they make haystacks to feed the livestock in the winter. Yup, that is a near universal need for any farming with animals, that is, a near universal foundat

1987? How could the poor students have known? Gee, 1987, I was at IBM's Watson lab as a researcher in their effort at the time in artificial intelligence. So, at the lab we had an ambitious computer services group, and they had for ou

It appears to me that Graham's essay is missing information and emphasis on one more crucial input to doing "great work" or being successful at all. That input is the importance of and good approaches to ===>>> Good

Mistakes? (1) By accident, I had a relatively good career going around DC in applied math and computing for US national security. I thought it would help my career to know more math so got a high quality Ph.D. in applied math. I WAS then

NYS crowded, right? Well, just look at a map, e.g., via Google maps. Can look for lots of wilderness places in NYS, but, to make looking easy, just go to the Catskills or, better yet, north of Albany. There are huge areas of forest. For

There is a point rarely mentioned but likely important: Academic research is highly competitive. Doing well in an academic career is essentially the same as doing well in the competition. In particular, the Federal government, Congress, t

US society has some important applications, roles, etc. for versions of relatively independent self-learning . Soooo, maybe somewhere in the teaching and learning of K-12 there should be some emphasis, practice, role, encouragement, etc.

As I studied Midway, the conclusion I came to was that the Japanese made a big mistake: They had two attacks for two quite different goals going at once, and the two conflicted and were one too many. The two attacks were (1) attacking the

On what design features came to market when, two examples: (1) In 1972, I was at Georgetown U., and IBM was proposing that we buy a 370/135 with virtual memory. (2) In 1973 there was the IBM 360/67 with 31 bit addressing, virtual

"Crazy new ideas"? A VC, Graham, is praising crazy new ideas? After I sent some hundreds of emails to Silicon Valley, NY, and Boston venture capital firms with nearly no positive feedback and nearly no feedback at all, I conclude

Uh, let's see: When I was buying math and physics books, it seemed that a lot of them credited the NSF with funding. I gave two examples, Kelley and Luenberger, but there were more. Soooo, there was some NSF pure math funding in the

I gave the prof's remark of "academic suicide" as an example of a significant attitude in computer science. I didn't claim that the remark was correct, and your examples show that the remark was not correct. But the mor

Your points are well taken. But the more likely explanation for the professor's reaction was just that doing anything in programming language design would be "academic suicide". The date of his remark was about 1974, and I w

You might be correct in part or in whole. We'd have to discuss back and forth! My (1) and (2) will have to be at best only rough, and to save space I omitted the real examples I have in mind to formulate those two. Writing clearly,

From my experience, among academic computer science professors, the attitude is that computer science is about the "fundamentals" of computing. E.g., once I was talking with such a computer science professor and listing features

It appears that roughly the point of the OP (original post) is that in math there are two cultures (1) people who want to develop new fields of math with definitions, theorems, and proofs and (2) people who want to use math, all or nearly a

I cook the pork to 165 F for food safety and to melt the collagen, and both of those are necessary and need the heat. The intention is not to dry the proteins: Generally as soon as the collagen is melted, the pork is done and plenty moist

Yes. In the trial I described, I used a 225 F oven for about 2 1/2 hours to get the meat internal temperature to 165 F. Then I lowered the oven temperature to 170 F and, wonder of wonders, 8 hours later the internal temperature of th

BBQed pork? Okay, I'll chip in: === Qualifications From age 5 to 22, I was in Memphis. I was there again from age 30 to 32. At ballpark 8 ounces of pork BBQ a month, that would be (1/2) * 12 * 20 = 120 pounds of pork BBQ consume
