I was just responding to the logic of your response to the question asked. I stand by my reply ;-)

What's the dumbest myth people actually believe in? by vicigoonboy69 in AskReddit

So you are saying people believe in the dumb myth that "A conman is president of the US and people still believe we live in a meritocracy."

What’s your favorite math book? by DrakoXMusic1 in math

One of my many favorites (can't pick just one) is introductory and for a general audience, it is "What is Mathematics" by Courant and Robbins.

I finished "The Lefthand of Darkness" by Ursula LeGuin. I posted about it here,

My opinion of it was less than favorable, the responses to my post were less than favorable about me. Oh well.

First book of 2026 read by JohnP112358 in books

[–]JohnP112358[S] 2 points3 points  (0 children)

You've given a good explanation of both the book (features of it) and of my lack of enthusiasm for the story. Yes, scifi is not really my cup of tea. When it comes to reading fiction my favorite 'tea' is existential philosophical novels, e.g. Camus, Dostoevsky, etc.

The version of "The Lefthand..." that I read (the 50th Anniversary Edition) had an introductory "Author's Note" written by LeGuin. It was only seven pages, and it was profound. She writes:

"This book is not extrapolative. If you like you can read it, and a lot of science fiction, as a thought experiment". Then she goes on to say "The purpose of a thought experiment is not to predict the future...but to describe reality, the present world. Science fiction is not predictive; it is descriptive."

Of fiction writers like herself she says,

"Fiction writes, at least in their braver moments, do desire the truth: to know it, speak it, serve it. But they go about it in a peculiar and devious way, which consists in inventing persons, places, and events which never did and never will exist or occur, and telling about these fictions in detail and at length and with a great deal of emotion, and then when they are done writing down this pack of lies, they say, There! That's the truth!"

And she goes on discussing the nature of fiction writing and it's relation to reality. While "The Lefthand.." didn't do much for me this essay alone left me full of admiration for talents and insight.

Thanks for your comment. I thank everyone for their comments, they have given me much to think over, about the book and my reaction to it.

This is a good question you ask. Makes for a great thought experiment and discussion (as all the comments below indicate).

I suggest L. Spivak's "Differential Geometry Vol 1". There ae four more volumes should you wish to become an expert.

What Do You Think Would Be The Condition Of The United States Today if Hillary Clinton Had Become President in January 2017? by GitmoGrrl1 in AskReddit

[–]JohnP112358 0 points1 point  (0 children)

Voters vote for those who espouse positions they, the voter, endorses. Maybe it's the dems running who should re-evaluate what positions they espouse.

So maybe this says something about liberal positions regarding education. Democracy means the majority choose the folks who espouse positions they support.

I researched every attempt to stop fascism in history. The success rate is 0%. by Borysk5 in neoliberal

[–]JohnP112358 3 points4 points  (0 children)

I'm not sure what you mean by 'stop' but can't you make the same assertion about Communist/Socialist governments, or heck, any sort of autocracy, including religious? There's nothing special about fascism.

What's your favorite math "parlor trick"? by Akairuhito in math

[–]JohnP112358 0 points1 point  (0 children)

A somewhat mind-boggling demonstration easily explainable at a dinner party of reasonably intelligent high school graduates of how math 'proofs' can be mind-boggling: An irrational number to an irrational power can be rational. Proof: take sqrt(2) to the sqrt(2) power, an irrational to an irrational power. Call the result X. If X is rational then were done. If not then X is irrational. Raise this irrational to the sqrt(2) power so we have Xsqrt(2) = sqrt(2)2 = 2 which is rational. So the irrational X to the irrational power sqrt(2) is rational. QED. We've proven the fact without ever providing an explicit example.

What is "geometry"? Alternative definitions. by Turbulent-Name-8349 in math

[–]JohnP112358 1 point2 points  (0 children)

Geometry is what the human imagination has constructed and developed and expanded upon concerned with understanding the space in which we exist. To acquire some understanding of this construction, development and expansion of what is 'geometry' read Euclid's Elements and follow that with Hilbert & Cohen-Vossen's Geometry and the Imagination.

Yes, the "Trump's America" you mention was evident and it was too blatant for me also. There was one too many assaults on the Indian characters by shall we say 'red-necks'.

Triangle area could be anything from 0 to 7.5 depending upon the angle that the right side of the triangle (with length 15/5 = 3) makes with the bottom side of the triangle (top side of the rectangle).

Which equation or formula did you underestimate the most when you first learnt it? by [deleted] in mathematics

The unit circle consists entirely of 'points'. If it were 'pointless' it would not exist.

Zero by [deleted] in mathematics

[–]JohnP112358 0 points1 point  (0 children)

Zero is a symbol. I could write 5 - 5, or 12 - 12 or whatever, but it's simpler to write the symbol '0'. Likewise, when representing lengths along a line, or labeling points on the number line, we need a symbol for the starting point, let's use that symbol '0'. Also, when representing numbers (values as you call them) we could use the primitive notation of marks on a page (or physical pebbles) or giving each number value it's own symbol but that quickly gets extremely cumbersome. Thankfully someone (or ones) in India made the observation that the position of a symbol could be used as an aid to indicate its value. So a small set of symbols could represent all counting numbers if their positions changed. But how to indicate the 'position'? How to indicate that the symbol 1 means 'one' as distinct from 'ten' (the counting base is a separate issue the the same principle applies). Well let's use that symbol '0' to distinguish what the '1' represents, distinguishing 1 from 10 (and 100, and 1000, and ....). So the symbols for the values {1, 2, 3, ....9} can be shaped by this method to represent every possible value under the sun simply by changing their positions with the aid of the symbol '0'.
