The Drunkard s Walk is a book about randomness, a topic that most people, unless they happen to be mathematicians or have a strange fascination with statistics, probably don t think too much about As a species, in fact, we generally prefer not to dwell on randomness, but rather to assume that we are in control of much of our lives than we actually are In this new book, physicist Leonard Mlodinow attempts to show why underestimating randomness is really not a good idea He lays a foundation for t [...]

This is a very fun, entertaining book about the myriad ways in which random phenomena affect our lives There is nothing really new here As a physicist, I am already well familiar will all of the concepts introduced, concerning probability and statistics But oh what a variety of fascinating applications I love the story about the Ask Marilyn column in Parade Magazine Marilyn vos Savant holds the record for the world s highest IQ She discussed the famous Monty Hall problem, and got aggravated lett [...]

Yes, I was an English major so, yes, I LOVE literature, but my statistics courses were my favorite courses ever I can t claim to be an expert statistician since I haven t run a chi square analysis in eons and since I can only remember the phrase data set but can t remember how to collect one kidding , but COME ON Some of Mlodinow s information is interesting, but much of his logic seems unfounded and certainly begs some sort of question and often a rather basic one at that I ve only finished 1 3 [...]

I hadn t realised I had read this guy before, and remarkably recently Euclid s Window The Story of Geometry from Parallel Lines to Hyperspace was a fascinating read and oddly enough, I was even reminded of it as I was reading this one and I still didn t put two and two together an appropriate enough metaphor for books on mathematics until I was well over half way through They are very similar books presenting an entire field of mathematics to a non mathematical audience from an historical perspe [...]

Lots of people might think they can compute the odds that something will happen For instance, If my favorite baseball team is playing an opponent with inferior stats I might be pretty sure my guys will wind place a small wager But random chance which is the rule rather than the exception could trip me up A so so batter on the other team might miraculously hit a grand slam home run In this book Leonard Mlodinow explains how randomness affects our lives For example, a publisher rejected George Orw [...]

There is a lot that is disturbing in this book Are we Masters of the Universe Not so much.The author discusses in a breezy, easy to understand conversational manner how randomness and chance are behind many human decisions which we believe to be either based on educated guesses or personal skills, as well as how luck functions far than we know in how things turn out for us Briefly, but entertaining all the while, the author discusses famous incidents which illuminate the psychology behind mista [...]

My mom carried a holy card of St Jude with her at all times St Jude is the patron saint of lost causes This book suggests that lost causes and what the public commonly refers to failures may just have had bad luck Mlodinow demonstrates a lot of what the world chalks up to superior skill or thorough preparation is actually due to randomness Or as Ecclesiastics states, in perhaps less scientific but concise terms I have seen something else under the sun The race is not to the swift or the battle [...]

Even better the second time This little book is just so good not only does it give you just enough math to make you feel curious and satisfied, it tells a ripping good story about probability theory and statistics, providing along the way compelling portraits of the eccentric scientists and mathematicians who contributed to the fields This time, I wanted to refresh my memory of all the thorny problems probability and statistics give us we are really, really bad at intuiting probability, as psych [...]

Let s suppose you are on Let s Make a Deal with Monte Hall There are three doors to choose from Behind the doors are a goat, a can opener, and a new car You want the new car You pick door 3 Now Monte Hall says he will trade you door 3 for door 1 First he shows what s behind door 2 a goat Now should you trade door 3 for door 1 in the hopes of getting a new car Here are your three choices A Trade because the odds are greater of getting a new car if you trade, B Don t trade because the odds are les [...]

The weirdest thing about reading this book was the following I watched the movie 21 in which a team of college students under the tutelage of a greedy professor make tons of money in Las Vegas by counting cards while playing Black Jack In one scene of the movie, probabilities are discussed and the professor brings up the scenario of the 3 doors on Let s Make a Deal and asks the class if it s better to stick with your first choice of doors AFTER the host reveals one of the doors behind which ther [...]

I ll admit it I like books by Malcolm Gladwell and Dan Ariely I liked Freakonomics A Rogue Economist Explores the Hidden Side of Everything and Mistakes Were Made But Not by Me Why We Justify Foolish Beliefs, Bad Decisions, and Hurtful Acts I know many consider these books lightweight and pseudointellectual, and that a incisive critical reader than I am would probably make mincemeat of them But I find them entertaining and interesting, even if they don t always hold up to critical analysis.The [...]

I have a math background and an interest in the mind and enjoyed reading books like Predictably Irrational and Thinking, Fast and Slow Given Mlodinow s reputation as a physicist, I expected a reasonably sophisticated presentation, albeit one that did not require a heavy math background I was prepared for the book to be basic and probably start with the rudiments of probability, but the presentation is SO basic that the title term drunkard s walk does not even occur in the book until page 176 out [...]

Despite the seemingly highly rated reviews this book has received, I suspect it is of a case of this book was hard to read which means it must be good that accounts for its ratings rather than any credit to the author s writing.The Drunkard s walk, despite Mr Mlodinow s attempts at following Mr Gladwell s formula, does not succeed in copying Mr Gladwell s easy to read voice as well First of all, although the subtitle SAYS how randomness rules our lives, I actually found the book to be propogati [...]

Fascinating book It was interesting how many people I spoke to about this get very passionate about randomness Many people think acknowledging randomness is denying God.The book is a bit chatty, and needs to focus a bit on errors people make with statistics in their personal lives but Mlodinow hit on an essential concept.I liked this lesson that successful people are lucky, but that lucky people are persistent, flexible, and brave.

You re presented with three doors Behind one door is a car and behind the other two doors are goats Sound familiar It is You pick door number one Instead of opening your choice, Monty opens door number two and reveals a goat He then asks you if you wish to keep what s behind your original choice door one or change your mind to door number three If you think it makes no difference whether you switch or not and that your odds are 50 50 either way, you might be surprised at the answer and enjoy rea [...]

So this was pretty good I had it on my to read list for awhile so I may have built it up a bit too much in my mind before getting started though because I kept waiting for the book to pick up in some areas Overall though good read, really enjoyable A lot of these anecdotes have been used before though I think he could have come up with a few unique scenarios Still it was fun I have always thought the wine ratings were a bit suss anyway.

If we were all unfeeling iRobots floor cleaners who respond to the random encounters in our lives by simply changing direction then the premise of this book is justified, for we would all follow our individual drunkard s walks to whatever probabilistic future awaits us view spoiler However taking this a step further, Leonard Mlodinow suggests that much of how our lives transpire is happenstance, defined by a supreme law of probability that governs what we experience and perceive as humans This c [...]

I confess to math envy I can understand general concepts and ideas if they re presented in verbal form Show me a page full of numbers and mathematical symbols and my brain freezes up like a sprinkler at the North Pole That s why I find books like this one so helpful Maybe it s not helpful, since I can finish a book like this and have no less arithmophobia than when I started, but at least I can wrap my head around the concept The drunkard s walk is a phrase that came into use in the 1930s to des [...]

I found this book fascinating I knew I didn t understand statistics, but I didn t realize how little I understood about randomness and probability The Monty Hall problem aka Let s make a deal , Ch 3 the effect that naming a girl child Florida can have on the probability of having two girls Bayesian theory, Ch 6, p 107 the errors that people consistently make on relative probabilities see, e.g p 36 40 I especially liked the sections on how we tend to find patterns where there are none, to base de [...]

this book is great it takes you through the history of how the statistics and probabilities we understand or try to understand today were first proven It s amazing how probability is just simply not an intuitive thing for the human mind be prepared for some anecdotes that will leave you scratching your head Mlodinov examples of human biases are entertaining and thought provoking Anyone who likes interesting factoids, data, or wants to understand the world better will find this a good read.

Overall I ll give it to Leonard Mlodinow for writing a math book that s surprisingly accessible to the general public Well, maybe it s not exactly a math book, or even a statistics book But there s a fair amount of each and he did a fine job with keeping it generally light and interesting Mlodinow explains that there are basically two definitions of random, and they don t always go together pp 84 85 The first is by Charles Sanders Peirce and basically states that a process or method is truly ran [...]

Ein richtig gutes Buch f r alle die, die sich ein bisschen f r Mathematik interessieren, aber in der Schule so wie ich sp testens bei der Integralrechnung ausgestiegen sind Unterhaltsam und anschaulich wird einem vor Augen gef hrt, wie leicht man sich bei statistischen Fragen oder bei Wahrscheinlichkeiten t uschen oder auch im wahrsten Sinne des Wortes verrechnen kann Manches wird ein bisschen aufdringlich wiederholt ok, Lektoren und Weinexperten sind auch nur Menschen , und manches ist ein biss [...]

Questo un libro potenzialmente molto interessante ma ho faticato non poco nei numerosi passaggi in cui l autore affronta le varie casistiche da un punto di vista strettamente matematico e probabilistico Ho apprezzato molto gli approfondimenti storici di vari fisici e matematici per citarne alcuni Cardano, Pascal, Newton , ma ritengo che La passeggiata dell ubriaco richieda una consistente dose di concentrazione e un minimo interesse per il calcolo matematico e io purtroppo manco soprattutto del [...]

A great little book about statistics my college minor , written by a professor of physics my major field of study.I got my minor 11 years ago and haven t used statistics since I ve been aiming to take it back up again maybe even do a career switch to data science sometime down the road, at least two textbooks and a few online courses away not to mention that I don t know of any data science openings in my city and I love my current house, and so does my husband I figured that plunging myself int [...]

This is an enjoyable synopsis of basic principles of probability and statistics Lest that sound like an oxymoron, Mlodinow really does manage to be entertaining while covering such topics as Pascal s triangle, normal distributions, standard deviations, Chi square analysis, Bayesian analysis, and type I and type II statistical errors He weaves in thought provoking questions and injects interesting anecdotes about the mathematicians who came up with these ideas If you are a mathematician, you won [...]

A very good and accessible introduction to probability and randomness Most people don t appreciate the fact that most of what we see every day is the product of chance Social scientists are, ironically, sometimes blind to this fact than others, because we are trained to hunt for patterns, and we therefore tend to find them even if they aren t there For anyone who does statistics, one way of thinking about this is that the typical social scientist routinely underestimates the magnitude of the er [...]

This was far froma random walk through the history and application of statistics and probability to ebryday life, although the typos in the last chapters of the kindle version might support the opposite conclusion Although many of the topics are familiar to late high school early university maths courses, the history, anecdotal illustrations and examples are woven together to build an enjoyable story of what is generally considered to be a dry topic Most of the examples are not heavy on the math [...]
