Travels with Charley (JDC #11)

Steinbeck left us a lively record of an ancient US



I had a great treat reading Nana and Poppi's (my grandparent's), 1962 version of this book. Steinbeck takes us along with his dog Charley on a trip through the US during a period characterized by the nation's racial growing pains. 

When I was in Salinas this summer with Neemu, we visited Rocinante, his truck and home during this journey, at The National Steinbeck Center (the link is to another blogger's page with some nice shots of the center - one is included below):


A journey is a person in itself; no two are alike. And all plans, safeguards, policing, and coercion are fruitless. We find after years of struggle that we do not take a trip; a trip takes us.

My wayward spirit makes me a natural consumer of a book like this and Steinbeck did not let me down. I love travel literature*, and if you do too, check it out^!  

____________
* Other books I have enjoyed that remind me of this one include: A Walk in the Woods (thank you India D.), On the Road, Zen and the Art of Motorcycle Maintenance, Big Sur, Dharma Bums, Fear and Loathing in Las Vegas, The Sun Also Rises, The Grapes of Wrath, and My Antonia.

^ You may have read a recent NY Times article that raised questions about the authenticity of Steinbeck's account. Check that article out if you haven't. It seems appropriate to quote Steinbeck here. On page 125, he appears to believe that impulse for investigation to reconstruct the past is simultaneously impossible to deny and necessarily insufficient to fully form an account of another person. After burning another man's lost court order to pay overdue alimony, he says: "Good Lord, the trails we leave! Suppose someone, finding [my journalling detritus], tried to reconstruct me from my notes."

The Moral Landscape (JDC - #10)

The philosophical basis for the science of morality


Unlike many of the other books I read, I didn't enjoy this book as much as I expected to. While the book raised a number of interesting philosophical questions (which I had almost without exception encountered elsewhere), Harris did not (and could not in the short book) engage much of the relevant philosophical literature on ethics. Of the scientific and anti-religious material he discussed, the book was at times engaging but, too often, poorly organized. 

Ultimately, Harris's motivation to ground discussion of morality in science is one to which I am very sympathetic. It is a motivation that results from his belief that moral questions are ought not be answered by religion*, to which Steven Jay Gould surrendered them with his non-overlapping magisteria. To the extent that I believe that religious evidence is irrelevant to questions in general, I agree with Harris (and Dawkins and others of the new and old atheists who have made this point). The most compelling frameworks we use to organize our experiences are those that are compatible with scientific/naturalistic explanations of the world. This includes moral and cultural values.

That said, we are a very long way from proving which code of conduct will yield the most "well-being" for two people, let alone two cultures (comprising billions of people in the world).^ It is probable that, like many interesting problems (deriving economic forecasts, predicting a chemical reaction from the first principles of quantum mechanics, solving the protein-folding problem in biology, proving or disproving that P = NP in computer science, or demonstrating the truth of a statement in a formal system), it is, in a general sense, intractable. If this is the case, there may be no obvious better system than making corrections to a free-market economy in a liberal democracy via scientific discoveries.**

There may be no chance of (stable) unconditional cooperation among man

Harris correctly points out that without cooperation his dream of higher and higher levels of well-being among nations will not be possible. There have been simulations of repeated interactions among agents that show that while unconditional cooperation is a destination for some game theories, it is often not a final destination.

Martin Nowak does an excellent job of describing the expected long term strategies in repeated games. What he finds in his model is not one final best policy of conduct but instead a repeating cycle of unconditional competition -> tit-for-tat -> generous tit-for-tat -> unconditional cooperation then back to unconditional competition, and on and on. 

Check out his lecture to the Royal Society:


I hope to read his book, Supercooperators next.

There are a number of reviews of the Moral Landscape if you are interested in points of view other than mine.
______________
* Typically when scientists rail against religion they are particularly angry with Western religions (the God of Abraham). If by religion we are willing to include Baruch Spinoza's "religion as naturalism" (God = Nature), then the two are completely overlapping (are one magisterium). Most religious people I know would consider Spinoza to be an atheist and as such would be unpalatable. Eastern religions can be even more compatible with naturalistic values, but these are typically not considered.

^ The fact that we do not even have a good definition of "well-being" was discussed in the book, but is perhaps a more important limitation than we fully grasp. Furthermore, even if we had a good definition that was universally accepted (not likely until we have a world without religion - ahem), we will have the problem of intractability. John von Neuman's, minimax theorem works for two people in a zero-sum game, but this is not one of those.

** To claim that there is a better solution would require an argument much more convincing than Harris has proffered. Other objections to any policy are: the problem of unintended consequences (Harris acknowledges), the problem of logistics (any solution relying on cooperation will have cheaters), the problem of evil, the problem of intractability (mentioned in previous footnote); and the problem of learned helplessness (via aid); to name a few. Check out Dead Aid to see possible unintended consequences of even our most humanitarian altruistic impulses:

#9: Incompleteness by Rebecca Goldstein

The proof and paradox of Kurt Gödel



I have admired Gödel since I read Hofstadter's: Gödel, Escher, Bach: an eternal golden braid. I hadn't read his work as a logician, but would talk with friends about it (and its implications) informally. That is, until I was chatting with Suman in 2008. He could tell that I would benefit from reading a popularization of his incompleteness theorems that dealt more directly with the content of his proof, so he and Anjali gifted me this book for my birthday (Harvey-mas).

The book was a joy to read (man have I been lucky with these books - I seem to say that they all are great). I enjoyed learning about Gödel's life - his life in Vienna, his work on the proofs, and his cherished walks with Einstein, another scientist who Rebecca Goldstein argues is intellectually exiled* by his theories/proofs - and the proof itself.

When I was an undergraduate in an introductory course on philosophy and discussing a number of important proofs, I found myself wishing for an airtight proof that the axioms of an argument were correct. Could there be assurance that I was using the right axioms? If not, I might come to the completely wrong conclusion despite using a rational argument. As you know, in any argument, the conclusions follow from the premises via rules of inference

At the time, I constructed an argument by analogy that no such proof existed since we could not imagine removing a condition, which we could not imagine removing (e.g. one could not imagine removing from the set of axioms that a human mind is a prerequisite for rational argument). Just as a fish would not have a concept for water (since it had always been fully surrounded by water and there had never been not water for it), so too, we humans could be fully immersed in some set of beliefs or conditions which would be impossible to imagine going without. 

Via Gödel's incompleteness theorems**, Gödel proved that such a program was useless: we cannot justify a set of premises in a logical system using the logic alone. If you are interested in the context from which Gödel's work arose, check out: Hilbert's program, and the Liar's paradox (i.e. "This sentence is false".

Implications of incompleteness

While many others extended the incompleteness theorems to the humanities, the computer sciences, and intelligence research (see Penrose for example), Gödel himself was more reticent to extend his theories. He does have this to say about the differences between men and machines though:

Either the human mind surpasses all machines (to be more precise it can decide more number theoretical questions than any machine) or else there exist number theoretical questions undecidable for the human mind.

By this, Gödel seems to suggest that either we are not like a machine (because our decision mechanism is not, at base, mechanical), and we have access to truths that a formal system would find unprovable; or else, we are at base complicated machines that have deluded ourselves into believing we have access to unformalizable mathematical truths.
_______________
* While both Einstein and Gödel achieved a large degree of fame for their discoveries, Goldstein argues that it was the world's subjectivist interpretations of each man's theory that lead to their respective marginalization. For Einstein and Gödel, their work bespoke the objectivist reality of Physics (physical realism) and Mathematics (Platonism).

** From Wikipedia: "For any formal effectively generated theory T including basic arithmetical truths and also certain truths about formal provability, T includes a statement of its own consistency if and only if T is inconsistent."

QED (Richard Feynman) and The Price of Altruism (Oren Harman) - JDC: #7 and #8)

Richard Feynman describes strangeness better than anyone


If you can't explain it to a six year old, you don't really understand it. 

Before QED, "Surely your joking Mr. Feynman" and "What do you care what other people think?", his autobiographical works, were all I had read. 

However, I was excited to read a slightly more technical work because no one puts complicated physical phenomena so simply. His wonderful humility, sparkling sense of humor and highest standards of explication are unmatched among the science writers I have read. 

It was a joy to learn how the probabilistic nature of photons lead to our everyday experience with light: it moves in straight lines, it bends (or slows down) in different media such as water, white light can be decomposed into its various colors when passed through a prism or diffraction grating, plus many more.

Some unanswered questions remain. I don't understand the origin of the complex component of the amplitude vector that Feynman gives to each photon in his vector diagrams. Although this was not a focus of his teaching in the book, it was something I would like to investigate further. This, combined with my excitement to learn more from whatever has been published of his masterful teaching, lead me to purchase the complete "Feynman Lectures on Physics." I doubt they will fall under the purview of the current Junot Diaz Challenge postings, but perhaps I will write some thoughts as I have them, here.

Altruism <= game theory + (multi-level) selection


Oren Harman's book about George Price is a very engaging, in-depth, discussion of the history of the science of evolution after Darwin. Two central questions of the book, and indeed, evolutionary biologists in the 20th century were: what is it that nature selects (genes, organisms, groups, populations)? What explains that a self-interested evolving unit (gene, organism, group) acts, at times, altruistically (accepting a cost to itself to benefit another)? Examples discussed in the book that shed light on these questions include: The sex-ratio in organisms (selection at the level of the individual should result in 1:1 and often does), virulence of viruses (natural processes of attenuation imply group selection may be at work), and the life-cycle of slime mold. Starving slime molds consist of single-celled amoeba which die for others (creating a stalk of dead cells) to allow other amoeba to climb and create a fruiting body (cells of amoeba higher up) which will be transported by animals or the wind to live another day (check out a nice movie of the process below).



(Fascinatingly, it was found that in the wild, these stalks are typically formed from a single clone. That is, the amoeba that group together are identical. They share the same genome and are therefore not anymore altruistic than a cell in my arm, which sacrifices itself after absorbing a toxin from the environment to protect a cell in my liver, or brain or any other integral organ to improve my survival chances and thus the chances that I will pass-on my genes - the very same genes that include instructions for reproducing that sacrificial skin cell.)

My history-myth about multilevel selection

George Price, among many others described in this book, were entranced by questions of how best to apply the ideas of evolution to solve evolutionary riddles. In particular, could altruism among units of evolution (genes and/or individuals and/or groups) be understood best by analyzing the problem at the level of the gene or higher up or both. 

Richard Dawkin's own wonderful book, The Selfish Gene, argues that the gene is the only necessary unit to consider when trying to understand a given phenomena. He envisions each individual as a vehicle or husk, for its genes. The gene is in a fight against all other genes to reproduce itself most effectively. The gene will only form alliances if that means that it will improve its reproductive success (as in the case of multicellular organisms).

This gene's-eye view of evolution is a powerful way to understand the evolutionary solutions to biological problems, and it, combined with William Hamilton's cost benefit equation*, can explain a wide-range of phenomena. Among these are wonderful game theoretic problems (introduced as a mathematical discipline by John von Neumann^ and popularized by many others including John Nash) such as the prisoner's dilemma that cast multi-agent problems in a mathematical frame (finding evolutionary stable strategies in a population).

However, it was found that the gene's-eye view is not mutually-incompatible with the view that group selection can also occur. Just as the laws of physics must always be obeyed when one employs a biological or chemical law to solve a biological problem (since the equivalent physical statement of the problem may be intractable or represent an inefficient solution path), so too rules of genetic selection must be obeyed (including the laws of chemistry and physics!) when one uses individual or group selection ideas to solve a problem. Harman summarizes David Sloan Wilson's work** on group selection as follows: 

...it began to become clear that the unit of selection [gene, individual or group] and the level of selection [gene, individual or group] depended entirely on different criteria. Of course genes were replicators, and clear units of permanence. But whether a certain level of life could be viewed by selection depended not on permanence but on where fitness differences resided in the biological hierarchy. Here is why: If a population is viewed as a nested hierarchy of units, with genes existing within populations and so on, fitness differences can exist at any or all levels of the hierarchy because heritable variation can exist at all these levels... Despite all the history and hype, the gene's-eye view and group selection are not, an never should have been, antithetical.

Price's mathematical treatment of trait change in evolution

George Price's work is a wonderful addition to this discussion because he provides the mathematical relationship that allows us to account for the average trait change in evolution due to selection and transmission. 


Here, Harman has used z and z(overlined) to mean a character (e.g. a phenotype) and its respective average value; w is the fitness of the character; and the covariance, Cov, and expected value, E, functions are as they are typically defined mathematically. However, if one wants to consider the resultant trait change due to transmission one level down (e.g. from organism to gene), we can consider the nested version:


where the right hand side is inputed iteratively as many times as needed (for each level). With enough data, we can imagine determining which of the terms in the sum is most important and attribute the relative importance of group or individual or gene selection. I have to admit that I have not seen this done, but would love to see an example of this to more fully appreciate its value. 

Overall, Harman's treatment of the history of evolutionary biology and his biography of George Price's life (of which I have not commented here) is excellent. I really enjoyed considering some of these wonderful problems and hope you will too if you have the inclination and the time. Thank you Scott and Veena for this thoughtful present.*^

______________________
* Hamilton's cost benefit equation states that an organism is willing to incur a cost, C if the aggregate benefits, B, to its kin, defined by r, are greater (rB > C). Ideal relatedness can be calculated: a parent or sibling shares 1/2 of genes (r = 0.5), each grandparent or uncle shares 1/4 (r = 0.25), each first cousin shares 1/8 (r = 0.125). Note these assume that there is no incest. The calculation is simple in that for every line drawn as a consequence of sexual reproduction, one simply needs to multiply the previous relatedness by 1/2. If there are multiple ways to reach a family member, the two paths are added (e.g. for a sister, 1/2 * 1/2 + 1/2 * 1/2 = 1/2 since I can think of the connection from me between mom and sister or dad and sister). Note that for half siblings, r = 0.25. Thus J.B.S. Haldane famously quipped:
I would lay down my life for two brothers or eight cousins.
Note that Hamilton's cost-benefit equation is being applied by J.B.S. Haldane at the level of the individual instead of the gene. Dawkins does this often in his book as well.

^ Incidentally, John von Neumann also provided the mathematical basis of quantum theory and is therefore the godfather of both of these books.

** For a nice review article on multilevel selection by David Sloane Wilson and E. O. Wilson check out this pdf.

*^Scott Johnson and Veena Reddy, now members of my family, gave this book as a gift to me a few years ago (this shows you how many books I still need to read) after I told them about my proposal to work with two microorganisms (distinct single-knockout mutants) in the lab to see if they could evolve to cooperate over time. With this platform technology (i.e. knock-outs which via natural evolutionary process maximize fitness through cooperation), one could engineer "multicellular" cooperative microbe populations that solve important problems (e.g. photosynthesize light and create biofuels [cooperation between algae and engineered yeast]).

The Calculus of Friendship (#6)

Taking it to the limit





If you like great math riddles, you will enjoy this book by Steven Strogatz about his 30 year correspondence with his high school math teacher. There are excellent discussions about Feynman's differentiation under the integral, riddles involving spiraling bugs (Gardner's Mathematical Games), cylindrical gas tanks (car talk), the Monty Hall problem (Let's make a deal), infinite series and steepest descent (epicycloid), among many others. Eric Kemer and I did some fun work on the spiraling bugs a about a year ago and have some other versions nice solutions to that one as well, if you're interested. I am still working on my proof of the steepest descent problem but thought I would share the Feynman example since I hadn't remembered reading about differentiating under the integral from Surely You're Joking Mr. Feynman. 

Feynman made good use of this strategy when evaluating integrals he did not know how to solve when in undergrad and graduate school (and even during the Manhattan Project).  It is done easily. For example, given the interval that high school students learn for the exponential function. From here, we can think of doing something strange (to compute a new, related integral) and differentiate both sides with respect to a. We have generated a new function for which we can calculate the integral. If you do this n times, you can derive the gamma function (when a is 1). How cool is that!

Junot Diaz Challenge: (100 books in a year): #5

The Brief Wondrous Life of Oscar Wao

Favorite themes in this one:
  • The role of the narrator and author in the creation of a story:
    • Analogy between "It's a Good Life" Twilight Zone Episode set in Peaksville, Ohio and any author and especially evil dictators
  • Spiritualism and magical thinking a waste of good time
    • There are really good examples of people who are convinced that their destiny is determined by an evil spell (fuku) instead of perhaps the more banal (more insidious) existential curse of living itself (randomness). Oscar and his family were doomed from the start of their adventure. Of course, they also participated in their downfall, but if they had done nothing, they would have also lived lives filled with suffering and pain. 
    • Ultimately the character's focus (past, present or future) and their mindset (optimistic, realistic, spiritual, pessimistic, etc.) are what they have some degree of control over.
    • Oscar is ultimately satisfied when he achieves intimacy (connection) with another person. And, at the end of his life, in his letter to Yunior, he says, "He couldn't believe that he'd had to wait for this so goddamn long...The beauty! The beauty!" In waiting, with his future outlook, he had lived his whole, short, life away
  • Narrator - Who is the Yunior? Why would he write this book? To understand his fate/history? Still owes it to Oscar/family/fuku? Fear? Love? Perhaps he is just a thinly veiled Junot.
I can't wait to see what the VI formers have to say about this... and am hoping to join their discussion.

In other news...

In case you are counting, you will notice that I am a bit behind my pace: we are one month down and I have read 5 books (off my 6 books a month pace while teaching). Not to worry, I am still working hard on this project and will be back on top of my rate in no time. Stay tuned!

Junot Diaz Challenge (100 Books in a year): #4

Advice to Satisfice

In America, if you put your mind to it, you can have anything you want; you just can't have everything you want. -Bernard Baruch  

Book 4 was a treat. Some of the most interesting topics included discussions of questions like: If choice and money are supposed to bring happiness, why hasn't general well-being risen over the last thirty years concomitantly with the significant increases in choice (in our market economy) and GDP?

Schwartz is not the first person to discuss this problem, but his answer is perhaps unique. He arguses that most of our unhappiness comes from too much freedom to choose in areas that are not worth spending time choosing. In particular, when given more choices, we tend to spend more time thinking about our options. This can have unintended negative consequences: we spend longer choosing and not doing the things we really love (opportunity costs); we do mental acrobatics which cost us emotionally as we weigh the options which can lead to feelings of dissatisfaction before and after (anxiety about a bad choice and later, buyers' remorse) our choice; we fall into the trap of believing that materialistic goals can lead to happiness (hedonic treadmill); and by considering more choices, the thing we ultimately choose will necessarily, be a decision not to choose others (we can't have it all) and our choice will suffer by comparison at least in one regard, if not many.

As you might expect, there are others who have thought about how people find happiness, and there has been lots of research on this subject. Nobel Laureate, Herb Simon first coined the portmanteau "satisfice," an amalgam of satisfy and suffice, which describes the strategy of choosing that which is "good enough" as opposed to "the best." Herb Simon suggests that when all the opportunity costs (time spent), real costs (money) and emotional costs (anguish) are considered, satisficing is generally the maximizal strategy. The best solution to (interesting) problems are solutions that are sufficient and satisfactory; they are NOT the objective "best" solution.

Schwartz has identified through his "Maximization scale" (a quiz you can take in the book) who among us are likely to be maximizers and who are satisficers. Furthermore, he finds that satisficers tend to regret their decisions less and enjoy life more, and more worryingly, an abundance of choice can turn a perfectly happy satisficer into a maximizer. If Simon and Schwartz are right, it behooves us to work to become better satisficers and be vigilant against too much choice leading us down the maximization road.

For people like me, who spend so much time thinking about the big decisions: marriage, career, religion, or which stereo to buy, this is welcome advice. I look forward to constraining my decisions in the future to two choices at most (one of the recommendations Schwartz suggests among other good ones in the last chapter of his book). If the options represent satisficing solutions to a given problem, then I can feel comfortable going forward with the one I choose. Philosophically, with the really big problems I have found that I can ameliorate my anxiety about not getting everything in life by appealing to the possibility that all universes exist and my observations are confined to the me living out the (admittedly wonderful, yet contingent) life I have in this universe.

There is an excellent and very watchable animated lecture on motivation that square with the work of Schwartz (and the research he cites) that provides a fuller understanding of why we are not satisfied with material goods. The lecture is given by Dan Pink, another popularizer of scientific research done on motivation, and author of the book Drive, which may be a future blog post. I encourage you to watch this video! In retrospect, this crisis of motivation was a big reason for why I left my job in the financial world.

Finally, if this work interests you and you want to read more, check out Ed Diener's and his son's, Robert Biswas-Diener's, work on subjective well-being (Will Money Increase Subjective Well-Being). The Dieners' are leaders in this field of work and they have many interesting things to say. For example, they have found that the extent to which a person preferences love to money is correlated with subjective well-being.

There are good, subtle arguments in the link above regarding considerations whether the causality flowing in both directions (if am satisfied with my life, might I be more likely to be a good mate choice and thus preference love to money; similarly, if I am not satisfied with my life, might I believe that I can solve my problems by focusing on money?).

Much of this work is interesting and of course we cannot read it all; I hope that my summary has been satisfycing for you.

Junot Diaz Challenge (100 books in 1 year): Book 3

A Small Book - A Small Place - A Large Joy


The third book I chose in this challenge turned out to be very good. A Small Place by Jamaica Kincaid was recommended to me by my wife, a ninth and tenth grade English teacher at our school. The book's assets for me included its high recommendation and its very short 81 pages of text. During a long weekend of student comments and advisee letter writing together, these were both important.

The action in the book is set in Antigua. The book's winding path considers both the legacy of corruption, which colonialism has bequeathed to the narrator's island culture, and the identity of its descendants. The tension in the book arises from ubiquitous boredom - an existential fact of life - that lead tourists to far off places. It is a source of double-suffering for natives, who cannot leave and are reminded of this fact daily in their lives when it is also personified in the form of the tourists.

Under other circumstances (see note about comments/letters above), I would love to write an essay on the work. However, I will quote from the book regarding the narrator's apprehension of the underlying banality of life as the motivation for the tourist and a dual source of suffering for the native:
That the native does not like the tourist is not hard to explain. For every native of every place is a potential tourist, and every tourist is a native of somewhere. Every native everywhere lives a life of overwhelming and crushing banality and boredom and desperation and depression, and every deed, good and bad, is an attempt to forget this. Every native would like to find a way out, every native would like a rest, every native would like a tour. But some natives--most natives in the world--cannot go anywhere. They are poor. They are too poor to go anywhere. They are too poor to escape the reality of their lives; and they are too poor to live properly in the place where they live, which is the very place you, the tourist, want to go--so when the natives see you, the tourist, they envy you, they envy your ability to leave your own banality and boredom, they envy your ability to turn their own banality and boredom into a source of pleasure for yourself.
The theme of banality in the tourist/native drama plays out, in miniature, the larger theme of corruption in the colonizer/slave relationship. An essay drawing out these parallels would constitute a very interesting and engaging challenge. Perhaps I will get to this once the other projects I am working on are done.

This book reminded me of some of my favorite ethical arguments against luxury purchases put forth in the excellent documentary "Examined Life" and some of Peter Singer's academic work and social work.

The Junot Diaz Challenge (100 books in 1 year): Book 2


For those in education (students/teachers) wondering how to read a 100 books in a year, I calculate that one and a half books a week during the semesters (8 months) and two and a half books a week during the breaks (4 months) should be about the right pace to follow:

(8 months/12 months) (1.5 books/week)(52 weeks/year)+ (4 months/12 months)(2.5 books/week)(52 weeks/year) = 95 books/year

Which brings me to my second book (just finished yesterday), Brian Greene's "The Hidden Reality"


The Hidden Reality is an excellent book for anyone.  It is by no means a prerequisite that you must have taken a college-level physics course, and if you have ever wondered about the physical basis for believing in other worlds, other versions of you, or vast distances in space or time, this is a wonderful book for your consideration.

Timely note: This book contains an excellent discussion of the work showing that we live in an inflationary universe, which was honored three days ago with the announcement of the Nobel Prize in Physics.  This work shows that space in the universe is expanding at an increasing rate.

Some of my favorite ideas that were discussed in the book include:
1. Quantum multiverse - one interpretation of the mathematics that describes events on the smallest scales is that every event is not preordained but is probabilistic and each of the realities (of all that could happen) actually are realized in alternate universes.

2. Ultimate multiverse - that if we can think it, it exists.  This idea is based on the principle of fecundity and was proposed by Robert Nozick in his "Philosophical Explanations."  I have referenced Nozick and his Epistemology before here.  It is a mind-bending take on reality, but together with it and the anthropic principle, an argument can be made that the construction "every possible universe" is actually "every actual universe."

Max Tegmark proposed the following (highly paraphrased) argument for this kind of multiverse:
  • A. Assuming that there is a Theory of Everything (a physical theory that can be used to describe all events in the observable universe), it must be writable in a formal system; otherwise, it would not be a theory.
  • B. But if it is a logical statement, it must itself be subject to the rules of mathematics/logic.
  • C. Therefore, there is no difference, in principle, between the mathematics associated with the theory of everything and everything itself.
  • D. Therefore math is reality.
The Ultimate multiverse is then the set of all the (different) universes which correspond to each mathematical idea/statement/system anyone could dream up.  The universe which we are in is just the universe for one particular mathematical system.  We happen to observe this one and think it is unique because it is just the solution to a mathematical equation which supports galaxies/planets/intelligent life.

This reminds me of the lyrics to "Neverending Math Equation" by Modest Mouse: "The universe works on a math equation / that never even ever really ends in the end"

Check out the Wikipedia Entry on Multiverse's here if you have a moment!
Words:
  • catoptric - of or relating to a mirror, a reflector, or reflection.
  • eyetooth - canine (tooth)
  • apoplexy - unconsciousness or incapacity resulting from a cerebral hemorrhage or stroke.
  • MacGuffin - A MacGuffin (sometimes McGuffin or maguffin) is "a plot element that catches the viewers' attention or drives the plot of a work of fiction".[1] The defining aspect of a MacGuffin is that the major players in the story are (at least initially) willing to do and sacrifice almost anything to obtain it, regardless of what the MacGuffin actually is. In fact, the specific nature of the MacGuffin may be ambiguous, undefined, generic, left open to interpretation or otherwise completely unimportant to the plot. Common examples are money, victory, glory, survival, a source of power, a potential threat, or it may simply be something entirely unexplained.
  • cynosure: a person or thing that is the center of attention or admiration : the Queen was the cynosure of all eyes.
  • mellifluous - sweet or musical; pleasant to hear: the voice was mellifluous and smooth.
  • fecund - producing or capable of producing an abundance of offspring or new growth; fertile : a lush and fecund garden | figurative her fecund imagination.

The Junot Diaz Challenge

A conversation with Junot Diaz

Junot came to our school recently and astonished us when he told us about the most important thing an aspiring writer can do to prepare for writing their first major work. What was astonishing was not the explicit language with which it was conveyed (although that was impressive), but the content of the advice itself: the successful writer, according to Junot, doesn't practice writing. He reads...a lot. His prescription is 100 books a year.

I did a quick calculation and realized this is about 2 books a week or 100 pages a day (assuming 300 page novels). It may not surprise you that this is not the first time someone has considered a challenge similar to this.

So I am taking up his challenge. Yesterday, I started "A final solution", by Michal Chabon, an admittedly small novel. But I am on pace as I finished it today.

Some excellent themes of the book: 1. The slip of the mind from erudition to senselessness with age and death (p. 101: Nice description of the awesomeness (and awfulness) of life continuing for others after it ends for us). 2. The ontological search for meaning: is meaning only in our minds or is it "out there" in the world (I have posted on this topic before)? When we find meaning in the babble of a parrot, is it warranted or is it due to an innate need for meaning. Chabon suggests that we overestimate the rewards of any search for meaning; however, ultimately, meaning does exist in the world, despite the fact that the banality of it can underwhelm us.
