But repetition is the heart of education, and this should be among the books we fans read. Collections like this should be â€” as it says in the description â€” accessible. He achieved his goal of covering a lot of subjects on various themes: My ideal is the cocktail-party chat: getting across a profound idea in brisk and amusing way to an interested friend by stripping it down to its essence â€¦The goal is to enlighten the newcomer while providing a novel twist that will please the expert. The essays on mathematics invite you to: digest infinities with different sizes, touch infinite small numbers and jump in places with many dim We are in 2018, Jim collected a bunch of essays on uncomfortable topics here called the edge of thought. There have been other examples especially in the metoo era, but the piece Holt includes is exceptional in showing how discussions about ideas and their lineage fit into broader academic dynamics. Calling this one done a bit before the end. In the 19th century Georg Cantor, a Polish mathematician, set out to prove that there was no limit to the natural numbers using an axiomatic foundation, i.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. The essays approach these ideas from a descriptive rather than technical standpoint, and many have a historical and biographical focus that place the mathematical concept in time. That, and the fact that the topics are covered independently in short chapters, made it easy to pause and reflect before moving on. The very best essays stuck with me long after I finished reading them, and I realized it was because Jim Holt had taken exceedingly complex ideas and distilled them down to their essences. There were definitely parts I liked though. I selected them for their depth, power, and sheer beauty of the ideas they convey.

I enjoyed his essay about Dawkins, for instance. Topics and people discussed definitely added to my reading list. It seems clear now that genius does run in families: among Nobel Prize winners in Economics there are remarkable connections Paul Samuelson and Kenneth Arrow are cousinsâ€”proof of Nature? It appears that some work on integration has paid offâ€”Hold refers to nine required dimensions. But he generally prefers to perch in the middle of a muddleâ€”say, the string theory warsâ€”and hear evidence from both sides without rushing to adjudication. But if it is eventually achieved, then any further existence of the universe is pointless.

Because of the inaccessible six extra dimensions, experimental tests of the theory have not been possible. . From this he concluded that there is no end to the natural numbersâ€”if 1 2 3 4 5 are your natural numbers, then 1 4 9 16 and 25 are the associated squares and the natural number 25 is larger than 5. Yet GĂ¶del, Escher, Bach remains a remarkable achievement. A delightful set of 24 standard essays and 14 brief ones a page or so on the history of physics and math and current views on their relations. One of my favorite essays includes a fascinating exploration of the concepts of the infinite and infinitesimal. Einstein said, all this string theory, and SchrĂ¶dinger's cat, or Einstein's boxes.

In this sci From Jim Holt, the New York Times bestselling author of Why Does the World Exist? But as heavy as the subject matter is, Holt writes in a manner that makes the topics interesting. The brilliant and tragic life of Alan Turing, who gave us the modern computer, and we gave him in return an early death for his homosexuality via either suicide or murder, a case closed but still mysterious. In fact, this was my experience for nearly the whole book. Less known though perhaps is that he was also the father of eugenics or the idea that human characteristics can be promoted or controlled through selective breeding. Hell, just the cover of lists examples of the arguments that Mr.

There's a history of the 'solve' of the four-colour-theorem and the associated problems it was essentially brute forced with computers, which angered many, which is what the essay is about! And then there's the philosophy part which sometimes utterly eludes me because so much of it is counter-intuitive. While noticeable, the reference never feels forced. Whether a byproduct of research, personal bias, or just being right there on his mind, Mr. But there exists certain scholars who wish to bridge the gap between those inside and outside the academic disciplines. Holt makes his recondite subjects seem not only fascinating but fun.

Holt a debt for piquing my curiosity about this strange genius. But that doesn't mean it isn't a consequence of being in a particular frame of reference. The rest of this review can be found elsewhere. How did scientists first deduce that the universe had hidden dimensions, dimensions that are curled up so tight we can't see them? I am never quite sure what to think of writings like this. Not all mathematical proofs are elegant. Much the same way a physicist drops Einstein or Feynman into conversation, Mr. Why do mirrors reverse left and right but not up and down? Leave a length of string or anything long, thin and flexible lying undisturbed for even a day and you will find it has somehow got itself tied into knots.

So many mathematicians wax poetic about the connection between beauty of their theorems and equations and truth. Ada Lovelace, the cult goddess of cyber feminism â€¦ was plagued by nervous crises brought on by her obsession with atoning for the incestuous excesses of her father, Lord Byron. Mandelbrot was a visual thinker interested in the shapes that nature took on. Much the same way a physicist drops Einstein or Feynman into conversation, Mr. Personally, I've heard that one needs to be bored in order to be creative: this was certainly confirmed while reading this book, as I got plenty of new ideas while struggling through the final three chapters.
