This is a delightful book. The books them is asymmetry in the natural world from the quantum level, to molecules, our macroscopic world and the heavens. The book is a well written and enjoyable journey from the late 19 th century to the present. It provides the accretive account (but exciting and not predictable) development of the Standard Model of particle physics viewed from the lens of asymmetry (symmetry). The journey has colorful personalities, accidents of discovery and historical attribution (fortune favoring the prepared mind). The book is filled with useful analogies and allegories and I found layers of my own confusion and misconceptions falling away courtesy of these helpful descriptions. The author uses words and a few selected figures and no equations.
The book culminates in the meaning of the Higg’s field, the discovery of the Higg’s boson and the anticipation of a unifying theoretical framework of the four fundamental forces with supersymmetry (SUSY). The book does not aim to look at the mathematical or physical limitations ( testability, falsifiability issues). It hints at the future but provides us (provided me) a clearer and firmer understanding and integration of the concepts and discoveries that have got us to this point.
I continue to learn a lot from Mathematica Stackexchange. It is a great resource. I have had some long and stressful days of late (and there are more to come). I get a lot out of contemplating the questions on the site. I learn from the expert users, I have fun trying to come up with an answer and I improve my communication skills in trying to provide a coherent, hopefully helpful, answer. The endeavour helps me process the baggage of the day.
I have not been an active review and only very recently looked into metamathematica.stackexchange. I found a wonderful, living active community. This blog post arises out of an interesting question regarding analytics on the Mathematica Stackexhange site. (it is here:
1:eJxTTMoPKmZmYGAoLkoGABNTAwM=…if a MSE user happens to want to look).
I have rerun some of the code (NOT MINE). I found solace, that despite being a casual and not acitve enough user (in editing, reviewing, closing) that I am a member of this community. There is a larger set of users but this focused on 100 users ranked by reputation. This seriously overcalls me but, even if a statisitical anomaly (my penchant for answering low level questions), I am glad to be part of this community that the analytics has peered into.
Here is a The community graph:
I am in community group 3 (the blue square)…
My other communities are in major flux. The following graphic, a comic expression of extreme frustration has has very deep roots in a sad reality of the present.
I hope all the communities we inhabit grow, develop and are resilient to the storms that come.
I read the first edition of this book. It is excellent. It provides a systematic approach/ It covers fluid mechanics: steady flow, unsteady flow, viscoelastic properties of tissues, Windkessel and more sophisticated models of the circulation.
It provides clear examples and figures from the in-vitro and in-vivo data.
The section of valve physiology and pathophysiology was excellent. The discussion on prosthetic valves, grafts and other vascular scaffolds was very instructive, clearly written with illuminating figures.
The book ends with discussion of measurement techniques: pressure, flow, velocity including discussions of doppler echocardiography, magnetic resonance imaging, computer fluid dynamics.
I hope the subsequent editions continue in this tradition and I look forward to seeing them.
This is a delightful book. I ‘inhaled’ it. I had some ‘laugh out loud’ moments. Simon Singh weaves the Mathematical secrets with historical vignettes and insights into the wonderfully creative writers of the Simpsons and Futurama. There is also a five part exam of sorts.
I admit to being one of those who recognized the Homer’s epiphany after wearing Kissinger’s spectacles (retrieved from the toilet) as homage to the Wizard of Oz…a confident but incorrect assertion by the Scarecrow after having been bestowed a brain by the Wizard…
I have enjoyed Simon Singh’s books, esp Fermat’s Last Theorem and The Code Book. This was an incredibly enjoyable read (from the view point of a fan of Mathematics and The Simpsons).
This post is motivated by the New York Times NumberPlay puzzle: The Princess Problem.
I was very late to this problem. The solution is very pleasing. It reminds me of the intermediate value theorem and the puzzle about meeting the monk on his journey up and down the meeting.
The puzzle can be visualized as a discrete Markov process:
I have plotted the strategy and 100 simulations of the journey through the rooms by the Princess. The horizontal axis is time. The vertical axis is the rooms. The purple “mountain” is the strategy and the red points are when the Prince successfully knocks (the first point of relevance). This is not a proof but a visual motivation towards one perhaps.
Note all all the even rooms are solved on the “ascent” and all the odd number rooms on the “descent”.
The clearest explanation of principles of Magnetic Resonance Imaging and insight into pulse sequences I have found.
This is a concise book. It starts with Lagrangians then Hamiltonians and provides multiple approaches for their derivation and their relationship. It also discusses commutators: their motivation and properties and use.
