The Afterlife

Thursday, October 27th, 2011

The best thing about the afterlife is that you can’t reason about it, because life after death is not pertinent to our domain of knowledge. Any “existence” after life would not be existence as we know it, and we wouldn’t be able to define it because it occupies a different realm (not in the supernatural sense, but in the sense of a knowledge base).

When we die, our physical manifestations – what we call our bodies (the physical medium that contains our consciousness and the vehicle that we can most precisely control) – cease to exist. The body disintegrates, and our earthly consciousness — which, I’m beginning to believe more and more strongly, is the recallable continuity of our interaction with the world that surrounds us — ends as well because we are no longer capable of interacting with the world or creating memories. But this doesn’t necessarily mean that there is nothing after death. We just can’t define what it is.

The way I like to think about the afterlife is an extrapolation of a feeling that sometimes overcomes me, a feeling so immense that I momentarily forget what I am supposed to be doing, where I am, even who I am. It’s just a flash, but in that moment I am pure existence.

The Fall of the Scientific Method

Thursday, October 27th, 2011

I believe the Scientific Method is, if not becoming irrelevant, at least losing its prominence in discourse throughout the world. As anything in the history of the world, this is just a cyclical movement, but I think we’re about to witness an inflection point.

Biased by the local version of history, we forget that the Scientific Method is only one possible paradigm of reasoning, one that particularly suited humans who found themselves in the Age of Invention and Exploration. When the number of phenomena being discovered is large and each strengthens the fundamental theories put in place, the Scientific Method feels adequate.

The Scientific Method is — my amateur definition follows — the process of rejecting theories through observed contradictory experimental evidence. Synonymous with modern science, it can’t prove anything about the world we live in. It can only evaluate theories for how bad they are.

People tend to forget that even the Ancient Greeks — our model of scientific thought — believed in reasoning that is a combination of the supernatural (mythos) and the rational (logos). For a long time, we have overemphasized the latter, dismissing alternative approaches to understanding reality, but as science turns strange and more distant, I believe we will begin looking for a basis of our understanding that isn’t rooted strictly in observation and rejection of theories.

Science is turning strange. To see this, let’s go back to 1905. The world was a fundamentally different place. All motion in the Universe was governed by a few simple rules first formulated by Newton. Mathematicians believed that every statement about the world can be proven or disproven (shown to be false, of course). We just learned to fly. We built automobiles and submarines, harnessed electricity, and were beginning to understand radioactivity. Maxwell unified our understanding of most of physics into an elegant set of equations.

Today, our laws — even the simple laws of motion — are more complicated. Sure, at low speeds they reduce to Newton’s beautiful equations, but this nonlinearity doesn’t give us much confidence that there is no third-order consequence, and beyond, that we’re simply yet unable to detect. Perhaps the rules that govern how the universe works are unknowable. Moreover, universe is already known to be unpredictable, in addition to being possibly inscrutable. Particles are in a number of states at the same time. The more we refine our models following observations which refute our hypotheses, the more science begins to look like, well, magic. And while we don’t readily admit it, I (and I am sure you, too) feel disappointed by it.

Science is also turning more distant. Many of the advances in physics don’t concern us beyond the drama of popular science narrative. It’s unlikely we’ll directly benefit from the discovery of the Higgs particle, but even if we eventually do (after all, DVDs wouldn’t be possible without Einstein, and his revelations seemed “unpractical” enough), we are adding layers of indirection between our theories and our lives.

Instead of focusing on observations, we can listen to our intuition (what feels right?), our sense of beauty (what is elegant?), or even simply focus more on fundamental phenomena and reason about what is not easily unobservable (what is entropy, exactly? What could the underlying cause of the Universe increasing in complexity be?). Doing this would not necessarily be equivalent to a rejection of logic — I simply advocate for us to go back to the axioms that we base our knowledge base on and revisit them. Once we settle on our axioms, we should absolutely use logic to deduce truths about the world. BUt that first step is crucial in defining what kind of truths we will discover.

Why would the rejection of the Scientific Method be good for us? For one, it may actually teach us something about the universe. Instead of tweaking existing theories, which are increasing in complexity and losing their elegance, we may be able to think outside the box: take an alternative approach, rethink everything we know about the universe, and settle on a much more intuitive and legible understanding.

A painful consequence of my philosophy

Tuesday, September 20th, 2011

A big problem with biking in Central Park is everyone else using the circuit, but especially pedestrians and joggers crossing the road, and casual bikers.

Riding defensively (slowing down near any pedestrian and casual biker, assuming that everyone is an idiot and will make a sudden move towards traffic) is simply impractical. It was my initial approach, but very quickly I realized that the resulting stop-go motion takes away from the entire pleasure of biking and defeats the purpose of having a circuit to bike on.

The fact is, you only have about one second to figure out if the person in the danger zone is an idiot (not paying attention), an asshole (having a sense of entitlement to think everyone else will move aside), or just efficient (is well aware of the surrounding and is in control of the path to ensure a collision will not occur). It’s harder than it seems.

In my desire to implement my philosophy of “commonsense right of way” I let the pendulum swing too far. A bruised tail bone and a whimpering jogger on the ground later, I was forced to revisit my approach.

  • Assume the other person is deaf. That was effectively the case with the aforementioned jogger who had her music blasting on at full volume. Or purchase a really loud bike horn (is there even such a thing?).
  • Watch out for signs of idiocy — a cyclist moving at 3 mph, swerving left and right, a jogger crossing the road in a direction almost parallel with the flow of traffic, a biker slowing down (they usually do rapid 90 degree turns, having gotten bored with riding their bike), people riding these rented tourist bikes

What do you do?

Friday, August 19th, 2011

I imagine, some time in the future, my child asking me a very simple question.

What do you do, daddy?

How will I answer this question? How do I want to answer this question? Will I be comfortable explaining (and if so, will I be able to explain) the financial services industry, how it makes people in this world better?

Maybe that’s how we should decide what to do with our lives — if we can explain it to our children, it’s a good thing to do.

On Invisibility

Thursday, June 2nd, 2011

So much in our society relies on some very fundamental (and seemingly sure) assumptions about the world and the rules that govern it. What if some of them ended up not being true?

For instance, we assume we can perceive the world as it is, on a macro scale. Let’s consider a simple thought experiment and suppose that a small group of people throughout the world had the ability to become invisible (and, say, affect the visibility of a small set of objects in their reach). What would the implications be? It is famously said that invisibility is never used for good, so with that in mind presumably what would be affected are societal standards, controls and guardrails; the sticks that ensure that our civilization doesn’t collapse in chaos.

We would have to seriously rethink security and the way we govern access. If I were invisible, I could board a plane very easily (staying out of the way of others would prove somewhat tricky, but I’m going to consider this a merely logistic problem rather than a fundamental one). I could walk past most security gates, likely only expect for those that use non-visual controls or ensure only one individual could pass the gate at once. Security would not only need to change; it would likely also have to be implemented in places where there normally isn’t any, as now the barrier for a breach is much higher. The world with invisibility would be a paranoid one.

What about other similar assumptions? How would the world change if we could suddenly teleport cheaply, safely and instantly to any place in the world? What if we could fly (have we built fences similar to what we build around turkeys)?

Technology in Overdrive

Wednesday, May 18th, 2011

It’s easy to get blasé about it, but if you stop to think about it, technology truly is in overdrive.

If you subscribe to technology blogs, you’ll know what I mean — the sense of being bombarded by new technologies, tools, gadgets, advances, and ideas. If you don’t and you buy technology magazines, you’re out of the loop already because these magazines are obsolete the day they come out.

It seems that new generations of computers and phones come out every year (this is certainly true with Apple products). In fact, technology products are now designed to last a very short time — battery that you can’t replace, OS updates that cripple old hardware — as opposed to the years or even decades that old casette players or even first CD players (my dad is a proud owner of one of those) used to serve their owners.

New standards coming out and adopting the philosophy of more rapid change — HTML 5, for example, is now a rolling standard. This will very likely push software and hardware makers to iterate more on their products.

Technology is creating a world where you have to sprint all the time because if you don’t, you’ll get left behind. This is true for the product makers, but also for the customers.

But what has changed, really? Magazines were out of date before, too, but somehow nobody cared. Vendors had their release schedules that were mostly unaffected by the higher level products’ release schedules. It seems that we want to have the information available to us sooner, in some strange kind of arms race, almost like the high frequency trading companies or news corporations.

More rapid iterations may seem to be accelerating progress, which is a good thing, but they may also introduce much more noise to the system. We’ll be so consumed with consuming the latest that we’ll lose sight of where we’re going.

Being Young

Tuesday, May 17th, 2011

Many people who are older than me gave me this piece of advice:

Take advantage of being young, especially a year or so after college. You have very few obligations and commitments, and you can devote large chunks of time on whatever moves you, whatever you are passionate about. Take risks, do things you’ve never done because the next good opportunity for that will be a few decades later and even then, you won’t want to take as many risks and you will not be in as good a physical and intellectual shape.

Which Number are You?

Monday, May 16th, 2011

Go down the list and stop once your answer is “no”.

  1. I would want to do something that would then save mankind from total destruction.
  2. I would want to devote a month of my life completely to something that would then save mankind from total destruction.
  3. I would want to devote a year of my life completely to something that would then save mankind from total destruction.
  4. I would want to devote twenty years of my life completely to something that would then save mankind from total destruction.
  5. I would want to do something that save mankind from total destruction but as I save mankind, I would need to die.
  6. I would want to die saving mankind even if people didn’t find out I did it until a hundred years later.
  7. I would want to die saving mankind even if there was a 50% chance that nobody would ever know I did it.
  8. I would want to die saving mankind even if nobody ever found out I did it.
  9. I would want to die saving mankind even if nobody ever knew mankind was in peril.
  10. I would want to die saving mankind even if everybody was convinced that a person Y did it.
  11. I would want to die saving mankind even if everybody was convinced that instead of saving mankind, I was the one that put it in peril.
  12. I would want to die saving mankind in all circumstances.

Comparisons vs Absolutes

Sunday, May 15th, 2011

I make this mistake all the time. Instead of thinking of myself on an absolute scale, having standards that depend solely on what I think is right and wrong, acceptable and not acceptable, good and inadequate, I constantly compare myself to other people.

I guess it’s human nature, to see what’s around us and compare. After all, a comparison is a much easier operation to carry out than an absolute assessment — the latter requires a good mapping from reality to something more abstract while the former is simple pattern matching. But there are many problems with comparing myself to others: I may end up spending a lot of energy on something that is irrelevant to what matters to me; I don’t utilize people I compare myself to to help provide me leverage (just like they should use me to get leverage) and instead end up doing things inefficiently–double-doing either explicitly or implicitly through lack of information; I may also think I’m done (if the comparison tells me so) while in fact be far from achieving whatever goal I need to achieve.

I wish I thought of absolutes rather than in terms of comparisons.

Progress and its Equilibrium

Thursday, May 12th, 2011

I see progress as the measure of our ability to solve the problems we encounter in our lives. As mankind learns to solve problems, we focus on the more complex ones (ones that are harder to solve, or those put in focus by the just-solved problems) — and this increasing complexity of the problems usually brings about the increased complexity of solutions (or the increased complexity of the research required to arrive at a solution).

Unsurprisingly, this is consistent with and deeply linked to the idea of increasing entropy. However, in my opinion continued progress is a state of unstable equilibrium — one between self-destruction and attrition. In the former, entropy gets a one-time boost followed by a lifetime of nil. In the latter, entropy increases at a decreasing rate thus proving the agents of progress (mankind) ineffective implementators of its underlying idea. It’s only that unstable equilibrium that fulfills entropy’s goal.

Mankind’s mission is therefore to maintain that unstable equilibrium.
