Book Review: In Search of Memory

February 25th, 2010

Every once in a while I read a book that is truly amazing, a book that leaves me thinking about it during those times of the day when my thoughts wander.  Godel, Escher and Bach is such a book, as is The Singularity is Near.  Last night I finished another such book, In Search of Memory: The Emergence of a New Science of the Mind by Eric R. Kandel.  As you might expect from the title, the book is primarily concerned with the sciences related to the brain and in particular the science of memory.  However, Dr. Kandel’s book not only is a wonderfully vivid discussion of neural science over the past century and a half, but a touching autobiography.

Kandel, winner of the 2000 Nobel Prize in Physiology or Medicine, was born a Jew, in Vienna, in 1929.  At age 10 the Nazis “invaded” Austria, and within the year he found himself in America.  Its is within the context of this start to life that he tells of his search for the biological basis of Freud’s theories, which ultimately leads him to the research of memory, many accolades, and an important place in medical and scientific history.

The science in the book is fascinating.  Kandel himself is a pioneer in neural science, but he spends many pages in each chapter discussing the brilliant women and men with which he has worked, many of whom have also won The Nobel Prize.  Kandel is a very talented writer, and exceptionally good at conveying complex scientific concepts to the lay reader.  The science of the mind is surely the most difficult of all of the medical sciences, and Kandel goes into detail while leaving the book accessible to the non-scientist.

When Kandel speaks of his past, his relationship to Europe and Vienna, his friends, and his family, he is particularly candid and touching.  The emotional depth of the book was surprising for me.  The man is clearly passionate about many things, and those passions ring through true and clear in the book.

At the end of reading the book I found my understanding of brain biology much greater, but I also found that I had learned a new aspect of the history World War II.  I also found that this man, who is obviously a talented scientist, is also Pulitzer-caliber author.  His writing is of such that I would wonder if this book might have won The Pulitzer if not for its scientific depth.

I cannot recommend this book enough.  It is one I am sure I will find myself revisiting in years to come.

A Brief History of Pretty Much Everything

The Best Idea Anyone Ever Had

November 25th, 2009

Today is the 150th Anniversary of the publication of The Origin of Species by Means of Natural Selection.  This is almost certainly the most important book ever written, and Charles Darwin’s idea has been aptly described as “The Best Idea Anyone Ever Had.”

Darwin waited nearly 20 years to publish his book.  The prominent theory on why he waited is summed as this: he was afraid of the negative backlash.  Darwin knew how deep his idea would cut across old mysticism, and also knew that it would not just be a flesh wound.  The idea of evolution wasn’t a flimsy knife, it was a mighty sword.  I believe Darwin understood that the very fact that the theory was so strong would be the thing that would make it so dangerous (perhaps for him).

During the time leading up to the writing of the book Darwin had researched the subject in great depth, and from then to the time of publishing had collected an even larger body of evidence.  When he did publish he did so with a well thought out theory that seemed to answer all the arguments against it.  He published a wealth (literally, for mankind) of knowledge that he had ingeniously analyzed and scrutinized.

How prescient this man was about its theory, and its reception!  Today, 150 years later, evolution is considered a scientific fact, so strong is the evidence in the view of the experts.  Predictions laid down based on evolution via natural selection have come true over and over.  We find new fossils yearly, right where they should be in the strata, right where they should be evolutionarily between already-known species.  We have found the “missing links” between the lower primates and man.  We now have molecular and DNA evidence supporting evolution.  In fact, there isn’t a single scientific fact known to modern biologists that disagrees with evolution.  Yet the old mysticism clings to bronze-age creation myths instead of recognizing the most well proven scientific theory ever.  Darwin was right about the science, but he was also right about his theory’s social implications, and that some would reject his theory without ever giving it a chance.

As a free thinking human I think this day should be celebrated as a high holiday.  Darwin’s achievement surely ranks with the discover of fire, the first written word, and Newton’s, Einstein’s and Heisenberg’s respective works in physics.  Sitting on top of the theory of evolution is all of modern biology.  Countless lives have been saved because of scientists developing medicine based on this knowledge.  It is a triumph of the human intelligence, one note in a song that tells us that we can shape our species’s destiny with critical thinking and scientific reasoning.

Growing Up in the Universe

I just stumbled across these awesome lectures by Richard Dawkins. They were done in 1991 as part of the Royal Institute series of Christmas Lectures.

Book Review: Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science

July 22nd, 2009

I just finished reading Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science.  The book covers the development of atomic theory, quantum theory, and most importantly, quantum mechanics in the late 19th and early 20th centuries.  The central figures are the de facto fathers of modern physics.  The author, David Lindley, doesn’t delve too deeply into the math or even hard science of the topic but instead focuses on the personalities of Born, Bohr, The Curries, Einstein, Heisenberg and others prominently represented in the book.

The author could have taken a deeper dive into the actual physics.  Throughout much of the book Einstein and Company battle Heisenberg and Company for “the soul of science” aka Einstein’s more classical views vs. Heisenberg’s quantum mechanics.  I would have appreciated a more thorough discussion of which concepts have really taken hold in quantum mechanics.  For example, Lindley discussed how the Schrödinger’s cat analogy (Schrödinger being from the Einstein camp) has been abandoned by modern physicists as misrepresenting what is know about quantum mechanics.  What are the facts, as understood by the leading physicists today?  I would have happily read another 10 or 20 pages covering what has made it into the modern view, and what hasn’t.  That being said, this book did a marvelous job framing the arguments so that they can be understood by the lay person.  The characters are brought to life and humanized.  I felt the author treated everyone more than fairly.  I would recommend it to anyone wanting a better idea of quantum mechanics without having to learn too much science.

Monty Hall, Being Wrong, Right, and Idiot America

June 22nd, 2009

There is a famous problem in computer science (hang in there with me) called the Monty Hall Problem:

Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?

You should switch your choice.  Disagree?  You are wrong!   Why?  Well let Wikipedia explain!

This is a really unintuitive one, but one that clever mathematicians solved a long, long time ago.  But a lot of people still disagree with experts in the fields. Why is this?  We all want to think we are smart, but are we all smart in all domains of thinking and knowledge?

I have been reading Jeff Atwoods series of articles on the subject for some time.  His blog is always an interesting read, but his recent article just dovetailed with a book I just finished reading, Idiot American: How Stupidity Became a Virtue in the Land of the Free. Mr. Atwood points to an article by Marilyn vos Savant in which she points out the answer to the “Monty Hall” problem above.  Her correct answer is is blasted by many of her readers.  Its funny she is right despite the opinions of many average Americans, and even many “learned” Americans.

In “Idiot America”, we learn about the tendency in contemporary America to give any given argument equal standing, no matter how ridiculous.  For example, the politically charged issues of evolution and global climate change are both painted by some in American as being “controversial”, yet they aren’t, at all, in the circles of science.  There is no controversy about evolution.  It is considered a scientific fact by biologists, paleontologists, and others.  Global climate change has become one one of the most researched topics of the last 50 years.  It is clear to specialists in the field what is happening.  At a recent convention of climatologists, the debate was not about global climate change, but about how to convince the public it was real.

Television personalities pull some 3rd rate weatherman out of East Kansas to debate a world-renowned Climatologist and both sides are given equal billing on Fox News.  It doesn’t matter that “East Kansas” is probably more concerned with local politics than science, and she/he hasn’t been published in a peer-review journal.  Never mind that the word-renowned scientist has been published, and thereby has had their credibility, skills, etc, put up for review by the peers (and passed).

This is the way our popular media now works.  Never mind the liberal or conservative slant.  Of course many of these talking heads paint all of science as liberal, and thereby political and wrong.  When the truth slant gets out of whack, we are all screwed.  When we quit giving respect to those in our society who strive to have, and gain the most education and accomplishment, we are in a bad place.  When we start giving more credibility to Rush Limbaugh than various, proven scientists, then we are more about ego and personal opinion than truth.

Earth from 10^23 meters to 10^-16 meters

I saw this today. Its a series of pics of Earth from 1023 meters (10 million light years) to 1016 meters (100 attometers). Pretty cool.

MIT Technology Review: Embryonic Stem Cell to Cure Blindness

June 18th, 2009

Here is a facinating story about the use of embryonic stem cells to cure blindness on the MIT Technology Review site.  It looks like it is going to actually happen. How cool is that?

I guess the douche bags that think the earth is 6000 years old and that a clump of 50 – 150 cells is a human being will be pissed.  The rest of us are incredibly happy to see such progress being made in a promising field of scientific research.

Book Review: Hitler’s Scientists

June 15th, 2009

I love science.  I wish I had had this passion for science when I was 18.  Back then I liked science and technology, but definitely didn’t have the drive for knowledge I do now.  I seemed to be naive, and I seemed to have a desire for beer and lots of it.

Fast forward a number of years, to about 2004.  I started to really get hankering, as the old cartoon says, for some science.  I don’t really know what sparked it in me again.  Perhaps it was the fact that I was working at a company that offered decent pay post dot-com, but was basically devoid of real computer engineering challenges.  Perhaps my mind needed more than what I was getting at work.

I started reading a lot of science non-fiction.  One of the first books I picked up in my newly discovered hunger was Hitler’s Scientists.  I had just finished reading Hitler’s Pope, and was also interested in more information about that interesting era.  Hitler’s Pope had been an great political/religious book.  On the other hand, Hitler’s Scientists was an excellent scientific book.  The name can fool you for the latter book.  While the book did involve several of the scientists that served Germany during WWII, it really covered scientific achievement from the entire era.  More in the next paragraph.

I cannot imagine being given a better education on the history of science from 1850 – 1950 than that offered in Hitler’s Scientists.  This was an incredible period for science.  The names that pop up from that time period are legends in human history, not just science.  Hitler’s Scientists covers the major achievements and the environments that surrounded all of the major discoveries of that age, especially in physics. Einstein! Heisenberg! von Braun!

As one would expect, coverage of science focuses on events leading up to, and including, Hitler’s rise to power and eventual fall.  The book continues on with chapters on the atomic bombings of Japan, and the US nuclear program post-war.

I cannot recommend this book enough.  It is one of my favorites books, and I have consulted it on more than one occasion after lively conversations involving subjects from the book.  If you are interested in WWII or in science, you will find this book more than fascinating.  Give it a try!

Book Review: Why Evolution Is True

June 11th, 2009

I just finished a fantastic book aptly titled Why Evolution Is True by biologist Jerry Coyne.  Coyne is not only a biology professor at the University of Chicago, but a talented science writer.  Science writers have a tough job. They need to convey scientific information in a way that non-scientists can understand, while staying true to the underlying science and not presenting a bias.  Coyne presents a mountain of scientific information in a fashion that conveys that you are looking at a mountain, but not climbing it.  And there is a mountain of evidence supporting evolution through natural selection presented in the book.

Coyne doesn’t take very long to get down to the business of presenting the scientific fact of evolution through natural selection.  The fact?  Yup.  Coyne drives home the point that evolution is not “just a theory” in the world of science.  Amongst paleontologist, geneticists, biologists and other scientists, evolution is considered a fact.  There is no debate.  Coyne doesn’t spend a lot of time talking politics, but he does spend some time putting the idea that their is any debate to bed.  Evolution is a fact, and this book takes a nice cross-sampling of hard-data from a number of scientific fields to present why scientists have come to this conclusion.

Along the way Coyne basically destroy so called “intelligent design”.  Coyne doesn’t do so with venom or malice, but I would imagine it would be fairly embarrassing to the ID crowd, if they took the time to read his book.  Coyne doesn’t really have to go out of his way to do this.  The arguments of ID seem shallow and poorly thought through when compared to the work done by scientists of the last 150 years.

The book is also littered with numerous scientific trivia.  I particularly enjoyed learning the fact that all humans actually grow fur in the womb, and shed it before they are born.  This is just one of many evolutionary artifacts that Coyne highlights in the book.  The illustrations are also fantastic.  There are a number of hand-drawn illustrations throughout the book that helped to highlight various scientific .

If you are into science at all, or are looking for an interesting read on how we came to be, I would highly recommend you read Why Evolution Is True.
