James Gleick

I really enjoyed the insight into the person of Feynman. He was, as any other physicist, a human with positive and negative characteristics. This is an important book because it captures this balance, which I believe is intrinsic to any "Genius" because the term focuses on some exceptional characteristics while ignoring the rest of the person.

The mental patterns I found most interesting in how Feynman thought were his reliance on fundamental characteristics of a physical relation and to show more visualize this in a way that he could gain a personal insight into the big picture of what was going on. He cared more about the units of measurement in a relation than the values. This is an example of what we might call genius because it is an unconventional focus on how to do physics.

And yes of course the maverick was also a bit of an asshole. I think anyone that dedicates that much time and energy to abstract processing suffers a price in social value alignment. show less

Review of: Time Travel: A History, by James Gleick
by Stan Prager (6-9-18)

I love flying because it offers an extended uninterrupted opportunity to read—and there’s even a drink cart! On a recent trip out of town, I packed two books. One was a novel sent to me by its author with a request to review it; it proved unreadable. The other was a chronicle of siblings who were executed for resisting the Nazis, a fine account that was nevertheless too depressing to be my sole read for the show more duration. Thus, while waiting for a connecting flight at an airport in Atlanta, I spotted a bookstore and walked out with a copy of Time Travel: A History, by James Gleick, which literally consumed me for the rest of my journey.
What if I had packed different books for my trip? What if I had the option to go back and make a different selection? Or, what if—prior to departure—I could have skipped ahead and evaluated how my choices turned out? Certainly, everyone at some point questions decisions made in life and yearns for that impossible opportunity for a do-over. Rarely, of course, would we muse over such mundane matters as to which book was plucked off a shelf. The choices revisited would more likely focus upon not having another drink before picking up the car keys, not sleeping with your wife’s best friend, or not taking the rent money to the casino. The flip side of looking back, naturally, is looking ahead to the consequences: the accident, the divorce, the eviction. But as we are reminded more than once in Gleick’s marvelous existential excursion into the scientific, philosophical and literary manifestations of the concept of time travel, our lives and choices are part of an even greater chaos system than the planet’s weather, and an authentic butterfly effect governs it all. So yeah, even your pick of a paperback could somehow end up changing everything, not only for you, but for those in your orbit, perhaps all of humanity.
Of course, Gleick—who specializes in science and technology writing and is the author of Chaos: Making a New Science—is something of an expert on chaos theory, although Time Travel is far less concerned with science than it is with how notions of time run through every aspect of modern consciousness. That was not always the case, as Gleick notes in an especially fascinating focus on how that came to change, relatively recently in our history, when the advent of train transportation and by extension train schedules—together with the communications technology of the telegraph—brought standardization to clocks across a vast network. The long pre-industrial agricultural world governed almost entirely by sunrise and sunset and the phases of the moon was all at once turned upside down. Clocks were not new, of course, but until regular train travel came to depend upon rigid scheduling, there was little pressure for the universal standardization of time. It was perhaps this now omnipresent sense of time, Gleick’s account seems to suggest, that sparked the whimsy to wonder what it could be like to travel forward or backward in it.
Time Travel opens with the guy who—it turns out—virtually invented the idea: H.G. Wells. While there were, Gleick recounts, prior random references to such a thing here and there, it was The Time Machine, Well’s 1895 novel—published at a time when the potential of science and technology seemed limitless—that conceived for a wide audience the very notion that travel through time might be plausible. The impact was immeasurable. For one thing, this slim work managed to generate a kind of massive cultural paradigm shift in the way those exposed to it perceived their past and future, riding Wells’ imaginary machine in their own minds-eyes: could it be possible to revisit the past or peer into the future? (Never mind that Wells himself believed it impossible.) For another, it spawned a whole cottage industry of science fiction tales in books—and later, in film—wrapped about this topic, the bulk of which are contained in this volume’s extensive bibliography. The reader suspects that Gleick has read or watched all of these, probably more than once, as throughout the narrative he skillfully employs these literary excursions to explore the philosophical and scientific ramifications of time travel. What if you went back in time and blocked Booth from shooting Lincoln, or killed your mother, or met yourself? These all seem like “timeless” themes now (pun fully intended!), but it looks like no one asked questions like these before Wells came along. And Wells didn’t ask them either: his time machine only went forward to a far distant future of Morlocks and Eloi, and beyond that, but not into the past. It was left to his literary descendants to tap those veins.
Given Gleick’s resume, I expected more of a focus on science in this book than naval-gazing, but that’s not to say science is absent. We think of the elasticity of time in our perceptions of it—we indeed experience the same units of time quite differently during orgasm and root canal, for instance—but Einstein revealed with his theory of special relativity that in the nature of the universe time is indeed elastic. Wells may have invented the science fiction about time, but it was Einstein, just a decade later, who uncovered the science of it. In fact, Einstein shook the halls of science at its very foundation when his work showed that space and time are part of a single space-time continuum comprised of the coordinates of four dimensions. I’m hardly a physicist, but the way I usually explain this to the uninitiated is by asking the trick question: What would happen on the earth if the sun suddenly burned out? The answer, of course, is: nothing … for about 8 minutes!
Time is, though, a tricky thing. On the macro level, there is something known as the “arrow of time” which proceeds in one direction, towards the future, along with the concomitant disorder known as entropy that is a component of the second law of thermodynamics, which accounts for the asymmetry between future and past. On the quantum level, on the other hand, we cannot be certain of that: underlying laws of physics work the same going forward in time as in reverse, meaning they are time-symmetric. Most of the physics beyond this are also beyond me, but Gleick does a competent job of summarizing the thinking about this attached to the best minds out there, from Einstein to Eddington to Feynman to Hawking—to the current cutting-edge science probed by the likes of Sean Carroll—from theories of relativity to those of the multiverse, in language fully accessible to the layman.
So, does that mean time travel is possible, to the past or the future? Gleick himself seems agnostic; others not so much. Some scientists consider that hypothetical wormholes—predicted by the theory of general relativity—might create shortcuts through space-time and could thus be a potential mechanism for time travel to the future, but that remains very speculative. Few think that travel into the past, reversing the arrow of time, could ever be possible. Others believe, like Wells did, that time travel is an amusing idea, but simply impossible. And then there are those, like some champions of the multiverse, who suggest that time is passing differently but simultaneously in multiple parallel universes, which makes you wonder that if time travel was indeed a possibility, rather than moving backwards or forwards in time, might it be more interesting to instead go sideways? Perhaps the accident, the divorce, or the eviction have different outcomes elsewhere …
There’s another kind of time travel that has a more secure scientific foundation. We know that Einstein was correct about special relativity, and although we cannot directly measure the space-time continuum, phenomena predicted by it have been confirmed. Einstein noted that the speed of light in a vacuum is always the same, regardless of the speed an observer travels, because the speed of light is absolute and invariable. This means that events might occur at the same time for one observer and at different times for another observer travelling at a different speed, because rates of time run differently based upon relative motion, something called time dilation. This is where the notion comes in of a hypothetical explorer on a space ship travelling near the speed of light who spends 100,000 light years in space on a voyage to a distant star and hardly ages at all.
Our science is not nearly advanced enough to put that to a test, but recently astronaut Scott Kelly spent nearly a year in space at high-speed orbit while—as part of a focused NASA study—his twin brother Mark remained on earth, and it is believed that Scott returned to the planet 8.6 milliseconds younger than his twin. On a more sobering note, unexpected changes to Scott’s DNA have altered his gene expression so that it now appears to vary by seven percent from that of his twin, and some of these changes suggest potential harm to his biological processes, perhaps shortening his lifespan. Contrary to what was initially reported in the popular press, however, Scott and Mark are indeed still identical twins, and much further study lies ahead before definite conclusions can be reached. But it does make you think and make you wonder …
If you are, like me, a person who delights in thinking and wondering, then Time Travel by James Gleick should be near the top of your “to-be-read” list. Whether your interest is in science fact or science fiction, this fascinating book—which truly defies genre—will make an outstanding contribution to your intellectual development. That is, of course, if you can find the time to read it …

The history of information theory is a history of increasing abstraction. To the point where the meaning of information becomes irrelevant. To the point where the universe itself can be seen as a giant computer, and each of our choices, thoughts, movements become like states in the machine. I loved reading about the African drummers who communicated over long

distances via a tonal drum language with built in redundancy. I loved reading about Babbage and his calculating machine, and to think show more about it as a kind of steam-punk calculator fantasy world of the future. I loved reading about people decrying the telegraph and the telephone as technologies that will ruin humanity. And to read about the shortening of telegraph messages to save time and money, with phrases like wyegfef which stands for 'will you exchange gold for eastern funds?' which is interesting because here we are in 2012

coming full circle, a form of regression maybe, by using codes like ROFLOL and BRB in our chatboxes and cellphones. And also that the telegraph reminds me a bit of twitter in its shortness. I didn't love reading about Godel and Turing and Shannon, but only because I've read so much about them already in other books just like this one, but it was still interesting enough. I liked reading about genes and the gene code ok, but I really loved reading about quantum computers because I knew next to nothing about them. Something I never thought about before is how a message sent using a quantum computer cannot be intercepted or wiretapped because of Heisenberg's principle

which says that you can't look at a quantum particle without effecting it, so in effect the intercepter cannot go undetected! This blew my mind. I loved reading the more philosophical chapters about how we have too much information for us to ever process, and how we must now deal with it. I loved reading about the library of babel and borges of course, how could I not? I loved thinking about how we have too much information and how everything is documented. "It did not occur to Sophocle's audiences that it would be sad for his plays to be lost; they enjoyed the show". I thought about that and I thought

about how every performance, ceremony, or event that I've been to in the last year or so has been recorded on video (and probably up on YouTube already) and how or whether that took away from the experience, whether knowing something will be archived later makes you pay attention less now, or is it a form of insurance, a kind of just-in-case, which then made me wonder how many times I (or anyone) will ever go and watch those videos again. I thought about the last chapters and how Google and other search engines are our only means of not being completely lost in meaningless data and then I thought about how much power the role of a search engine is, to make sense of the information is also to hold all the power, to control the information, to control what information people see or don't see. I'm looking forward to the sequel. show less

Gleick needs a time machine. He wants his reader to put him or herself back in the 1990s as much as possible when reading What Just Happened. We need to remember the internet as it was just starting out. Portable phones. Pagers. ATMs. The essays cover bugs in Microsoft (essays written in August 1992 and again in June of 1997), the transformation of cellphone communication, the question of caller ID and ethics, the Y2K Crisis (for which Gleick apologizes for reporting impending doom four show more years prior), the idea of anonymous spending is only possible with cash (Think about it. No other form of money is without identifiers of some sort.), humorous password creations - all with a snarky tone that is just delightful.
Gleick's opinion of internet pornography and its future is laughable. My favorite section was when Gleick unpacked an alert sent by MSN, pointing out vague language, half truths, cloudy communication, deliberate mis-directions, down playing failures, all with skillful ambiguity and clever concealment of the truth. Humor aside, Gleick makes you think about how far we have come. show less
