Week 32: Oprah's Book Club


Oprah's Book Club
On science and religion, and why scripture should know the value of its place.   

"Life is..." is a very different statement from "Life can be described by..."  This is because we can never say what life is, with absolute certainty; we can only infer life from its descriptions.  

Stated another way: We can never teach what life is; we can only describe how life works. Across these descriptions, patterns begin to resonate from which the true nature of life can then be inferred, albeit with varying degrees of uncertainty.  

From an infinite complexity of life arises infinite ways to describe that life. The two most commonly (mis)understood frameworks are, of course, religion and science. 

The former offers anecdotal descriptions based on scripture passed down incompletely from one generation to the next. The latter offers theoretical descriptions based on conclusions drawn from quantitative data passed down incompletely from one measuring device to the next.

Both frameworks paint incomplete pictures of life, but only science acknowledges that its pictures are incomplete.

Religion speaks in absolutes of what is and what should be; whereas science offers only theorems: statements that can never be proven true—only false.

Science accepts uncertainty as its central premise, and is in fact driven by this uncertainty to explore further, to understand better—to live more. Uncertainty, in a sense, is what gives life meaning: life as an end in and of itself.

Religion, on the other hand, is never uncertain. Uncertainty does not win followers, and without followers, there can be neither political support nor financial gain: Religion would go out of business. 

And so religion sells the false certainty of ritual and form, perpetuating an ignorance that does not explore, does not question, and simply obeys. "Look no further; ask no questions; do as you are told; and in the next life," religion promises, "you shall be rewarded." The promise of future rewards is what gives life meaning: life as a means to an end.

Religion gives people answers to questions that they aren't intellectually prepared to ask yet, and in doing so, shortcuts their journeys—straight into a ditch.  After all, why bother trying to learn new ways of understanding the world if some all-powerful deity is ultimately the answer to every question?

Some would argue that this isn't so bad: some people just aren't equipped for a lifetime of struggle. I can accept this. Self-imposed ignorance is OK with me.

But the hatred, discrimination, and violence that is often a product of this ignorance—not okay. And the only way to achieve self-imposed ignorance without the trifecta of hatred, discrimination, and violence is to free scripture to DESCRIBE truth, and stop forcing it to BE truth.
 
Scripture at its best functions like the greatest of literature: offering descriptions of life that while far removed in place and time, still resonate in the here and now through some shared and eternal struggle.

In this sense (setting my obvious biases aside), scripture does have a place in the modern world. But then again (biases reasserting themselves), one could also join Oprah's book club.

Week 27: The Things Reflected In My Eyes


The Things Reflected In My Eyes (瞳に映るもの)
Why photographs lie, and what beautiful photographs of ugly men can tell us about the nature of truth.

To be photogenic means to photograph well. It means that when four dimensions of space-time are flattened into two and much of your essence is lost, your physical attractiveness—at least—is preserved, captured in a photograph for posterity. 

Through Facebook, I find an endless supply of photogenic individuals at my fingertips. 

I often spend hours browsing through photos, indulging the horny little teenage girl in my mind who delights in filling in the gaps left by all the things not preserved, the dimensions that don’t photograph well.
This one with the strong jawline and caterpillar eyebrows? He seems like the tall brooding type, a quiet intellectual that finds solace in books and writing, but who can also carry himself well in social situations, and happens to love math!
When I meet them in person, and they turn out to be even more than I imagined, I hold my breath and pray for the day when all Californians can get married. 

More often than not though, Mr. Photogenic turns out to be anything but what I inferred from his strong jawline and caterpillar eyebrows. When this happens, it strikes at the core of my faith in mankind: How can a man so orgasmically beautiful be so heartrendingly stupid?

The fact that universally photogenic men can manifest so inconsistently in person is a testament to our multifaceted existence: We are not one-, two-, or even three-dimensional creatures; the essence of man spans so much more.

As beautiful as that sounds (yes I am aware of my tendency to gloss over ugly details), the fact is that there are some dimensions better left to the imagination: Sometimes, man’s essence can look like Maladora (exotically beautiful), but also smell like Maladora (pungently corpse-like).

I am sure photographers imagine their art is like a crucible. They frame the world through a camera lens, searching for that perfect angle, that perfect moment to crop out all irrelevancies and allow them to capture only what is important: the truth, as they see it.

But of course, multivariable calculus teaches us that 2 vectors cannot a 4-dimensional basis make. 

Photographs lie, and photogenic men can turn into the beastliest of boys, precisely because 2-dimensional images can only ever hint at the full nature of infinite-dimensional truths.

Week 26: Why Creationism is Dumb


Why Creationism is Dumb
How multivariable calculus helps us cut through complexity, recognize universal patterns, and thus discover our own truths—and why this scares the Pope.  

I met up with a new client at Cafe Flore today. She's a grad student at Cal taking multivariable calculus (scary!) over the summer.

I warned her that my multivariable calculus was a bit rusty, that I might not always be able to speak from a position of authority, that our relationship might have to assume a more egalitarian form—that we might have to work through this together. 

She seemed okay with it. 

Today's lesson dealt with the concept of basis, which is just a fancy mathematical way of saying coordinate system, or to generalize even further—frame of reference.

In multivariable calculus, where you begin working in more than just one- or two- or even three dimensions, a basis helps you make sense of a quantitative world that extends beyond the realm of sensory experience. 

I think NYU Professor Morris Kline (1908 - 1992) put it best:
"No one can visualize a four-dimensional, non-Euclidean world, but those who insist on visualizing the concepts with which science and mathematics now deal are still in the dark ages of their intellectual development. Almost since the beginning of work with numbers, mathematicians have carried on algebraic reasoning that is independent of sense experience. Today they consciously construct and apply geometries that exist only in human brains and that were never meant to be visualized."
In one of her problems, my client was given 7 different vectors (think of an arrow), each of varying magnitude and orientation, and then asked to find a basis. 

I explained to my client that the 7 different vectors were like sets of unidentified fingerprints lifted from a crime scene: one from the bedroom doorknob, two from a champagne flute, several taken from a bloody butcher knife...and so on.

To proceed with the investigation, she needed to determine if those 7 sets of fingerprints belonged to 7 different suspects, or if really there were only 1 or 2 or 3 unique suspects.

It was up to my client to eliminate redundant sets of fingerprints (i.e. those belonging to the same person) until only a unique set remained: to find the truth, the whole truth, and nothing but the truth.

The problem reminded me of a Star Trek episode, “The Measure of a Man” (TNG: 2x09). In it, Captain Picard offers this closing argument in the trial over Commander Data’s status as a Federation Citizen:
"Your honor, the courtroom is a crucible; in it, we burn away irrelevancies until we are left with a purer product: the truth, for all time."
To solve this problem, my client needed to find a basis—a frame of reference—that would allow her to cut through the complexity and see fundamental truths, to "burn away irrelevancies" until she was left with a purer product.  

And so she did.

She used the tools of multivariable calculus to slice away at those 7 random vectors, cutting through the redundancies, the extensions, the overlaps—the linear combinations—until only 3 remained, each pointing in a unique "direction."  

Out of a dense fuzz of complexity, a simple pattern of only 3 variables emerged. Here was the basis, the coordinate system, the frame of reference: the truth, for all time. 

The discovery is so spiritually uplifting that Pope Joseph Ratzinger himself is roused from his transcendent slumber and, in nothing more than his pointy Prada shoes, quickly issues a papal bull accusing multivariable calculus of molesting little children.   


The full text of Theodore P. Olson's Captain Jean-luc Picard's speech:
"Your honor, the courtroom is a crucible; in it, we burn away irrelevancies until we are left with a purer product: the truth, for all time. Now sooner or later, this man [Commander Maddox]—or others like him—will succeed in replicating Commander Data. The decision you reach here today will determine how we will regard this creation of our genius. It will reveal the kind of people we are; what he is destined to be. It will reach far beyond this courtroom and this one android. It could significantly redefine the boundaries of personal liberty and freedom: expanding them for some, savagely curtailing them for others. Are you prepared to condemn him [Commander Data] – and all who will come after him – to servitude and slavery? Your honor, Starfleet was founded to seek out new life: well, there it sits! Waiting."

Week 13: Your World. Delivered.



In the process of education, we immerse ourselves in different fields of study, laying down a sample size of data in our brain large enough to illuminate a coherent pattern. The more we learn, the more this pattern is refined, reinforced, and strengthened. This pattern then lifts us up, allowing us to see the world not as a forebodingly complex jumble of dissonance, but as infinite variations on a singular theme: the world becomes one. 

Through education, we are empowered to infer beyond the world of our five senses, beyond our perception of reality. Through education—we find faith.

In Week 11, when Billy tried to sound out the word “mathematics”, he was transforming a single, ominous and impossibly complex “sound” into a logical sequence of more familiar, easy-to-spell syllables. He took a complex word, framed it as a collection of syllables, and used this new perspective to decompose the word into smaller, more manageable pieces.

This is the exact same approach we take to add any multi-digit sum, such as 88 + 66. The down and dirty approach would be to start at 88 and then count a collection of 66 sticks, rocks, fingers, toes or some witches brew of all the above in order to arrive at the sum. But nobody does this—not anymore; modern mathematics allows us to sense and manipulate numbers more efficiently than that. In school, we all learned how to take a multi-digit addition problem, frame it as a collection of place values, and then use this new perspective to decompose it into a series of easy-to-calculate single-digit sums. The algorithm is simple: start at the ones place, carry over if necessary, move on to the next place value, and repeat.

Taking a complex problem, orienting it around a familiar frame of reference, and then decomposing it into more manageable components: this is problem solving! Through education, we expose ourselves to so many different frames of reference and familiarize ourselves with such a diversity of viewpoints that no problem is too complex.

Education: the entire world—decomposed at your fingertips.
