useless gifts

Here be dragons

A place for me to dump my ideas. I'm not sure exactly what is going to end up here. But I promise it will be useless.

Determinism, Again (2025-08-06)

I saw a post the other day that was criticising Character.AI-style romantic chatbots. Something like "wow, I can't believe you love a bunch of linear algebra and matrices."  And I thought... there's no difference between that and a human.

One of the formulations of Quantum Mechanics is Heisenberg's Matrix Mechanics.  Mathematically, the wavefunction of quantum mechanics is equivalent to a vector in a vector space.  The different physical operators become matrices, and the observed value becomes a matrix-vector multiplication.  The time propagator, that evolves the quantum system forward in time, is also expressable as a matrix.  Therefore, the complete behaviour of any quantum particle is able to be cast in terms of linear algebra and matrices, which neccesarily also includes all particles in your body and therefore your entire person.  So yeah, we're all linear algebra.

Note: vectors and matrices may be infinitely dimensional. Sorry about it!

Determinism, My Old Foe (2025-07-18)

[tw: su*cide]

There's an old meme that floats around scientific circles. This one hit me specifically, as I spent a good number of year studying statistical mechanics. I have some ideas as to why Boltzmann and Ehrenfest might have chosen to end it all, and it's not the difficulty of the equations. You see, I've long been interested in the origin of life.  When I was a kid, I intrinsically believed in dualism - I thought the living things were made of cells and non-living things were made of atoms.  When we later learned that cells were also made of atoms, this blew my mind completely and shattered my worldview.  I've since been haunted by the question of how "dead" matter can spontaneously give rise to life. As such, I majored in biochemistry, with a side of computer science just for fun.  This put me in a unique position to learn about a computational chemistry technique called "molecular dynamics," which to me has major implications on the philosophy of mind.

Molecular Dynamics (MD) is a way to use computers to study how atoms and molecules behave on the molecular level.  It may sound a bit familiar to anyone who's studied high school physics. let's say we have thrown a ball and it's in motion.  Starting at some time t0, corresponding to some position x0, and velocity v0, what will the position, x1, of the ball be at some t1 = t0 + Δt?
First, we need the force on the ball. For earth's gravity, we have F = m*g. Due to Newton's second law, we have F = m*a which means that a = g (g is called acceleration due to gravity so that checks out.)
then we can solve for the new position:
x1 = x0 + v0*Δt + 0.5*g*Δt^2
we can then repeat this process as many times as we like to see where the ball will go as time drags on. The choice of Δt is arbitrary, but at a small enough value, the path of the ball will be physically accurate.
What does this have to do with molecules? It turns out that atoms behave like balls, and atomic bonds behave like springs, connecting them together.  Using the same equations, we can simulate a molecule jostling around in a bath of water for essentially as long as we like.  We can use this to study any molecules we like, as long as we know their structure.  This includes all of the molecules that are in our cells, and MD simulations of biomolecules such as proteins are used to find new medicines.

Now, our computers are not powerful enough to study anything bigger than a single virus particle, but the principle holds no matter how big of a system you consider.  In theory, if you had a powerful enough computer, you could do a simulation of an entire cell: the membranes, the proteins, the DNA, the RNA, all of it.  But, why stop there? In theory, if we had a computer big enough, we could simulate an atom-perfect copy of an entire human being, living in an entirely simulated world.  What does this mean?

I don't think I'm bold enough to propose that we are currently living in a simulation, because that would take a mind boggling amount of compute power.  However, since there's no difference in practice between the behaviour of matter in the real world and the behaviour of matter in the simulation, and since we're all just made of atoms, this simulated thing ought to look and act just like a real person. And, crucially to me, any actions that this person makes would be entirely determined from the very start of the simulation.  There's no way for the person inside the simulation to "change" which way his atoms are going to move, which will cause his neurons to fire, which will cause his muscles to move, etc.  It's all very much like a movie.

To, the correspondence of these simulations to our real world means that everything in this life is essentially the result of a previous action.  Just as a domino in a set of dominos has no choice but to fall when it's hit, we to have no choice but to act a certain way when certain conditions arise.

And yet.

Here I sit, as a fully-formed independent thinking thing, having the feeling of complete determination over myself and my actions, maybe even my thoughts on a good day. This seemly flies in the face of what I know is happening inside my brain at this very moment: light from my computer screen is passing into my eye, through the lens, and into the cornea.  Once there, it is being absorbed by a tiny little molecule called Retinal  Upon absorption, Retinal changes shape.  This acts like a little switch, which then triggers a structural shift in the protein Rhodopsin (this is observable in MD simulations).  When enough Rhodopson molecules shift, They bind together and release a soup of signalling molecules into the cytoplasm of the Rod cell they are found within.  These signalling molecules eventually make their way to the synaptic side of the Rod cell, where they flood the synapse with neurotransmitter molecules, triggering the neighbouring neuron to also signal it's neighbouring neurons, and so forth.  This signal eventually reaches the brain, which is some kind of Rube Goldberg contraption of signals bouncing around, and eventually a nerve impulse travels down my arm to my finger, causing it to move to the next key and contract, typing the next letter in this post.  From a physics point of view, this was a purely mechanical process.  If you were to expand a brain to the size of a galaxy, you'd see quite a lot of stars and planets (the atoms) orbiting around each other in complicated patterns, but nothing that discernibly looked like thought.

The thought is enough to drive you mad.

No Garbage People (2025-07-04)

If there is one message that I would like to seed throughout the internet, one insidious little self-replicating meme for the ages, it would be this: there are no garbage people.

You see, in today's online culture, once you commit one unacceptable act,  or are found to have an unacceptable thought or point of view, that's it. You're done. You become a "garbage human being."

Maybe you're a racist. A homophobe. A transphobe. A TERF. A misogynist. A rape apologist. A colonialist settler.  A billionaire.

Or maybe you're a Liberal. Or one of those alphabet people. Or a jew. Or a commie. A junkie An atheist.

It does not matter, because they all mean the same thing: You're evil. A scourge on society. You are irredeemable, evil, and need to be removed from society in order to make things right.

The problem is... none of that is really true. Everybody has the capacity for good and evil within them. We like to imagine ourselves as victims and the others as oppressors, but in reality we are all both.

(I mean really we have Hollywood and Disney and Marvel to blame.  Always the "bad guys" versus the "good guys.")

I think in reality, we reject ourselves. We project all our negative traits onto the other, and then banish them. In so doing, we attempt to cleanse our own negative traits. But that doesn't change anything

But if we can tolerate the other, then maybe we can accept ourselves.

I stand for love. For Call-In Culture, not Call-Out Culture. For reform. For hope.  

For human recycling, not human garbage.

---------------------------------------------------------------------------------------------------

There are people who will read this and decide that I am a garbage human being, or evil, or whatever because they don't agree with what I'm saying. Maybe they think it's harmful or it legitimizes violence.

Let's be clear, I am against violence.  Far more than most of my peers, I'm sad to say. 

Many marginalized groups today have been on the receiving end of a lot of violence and they feel like the revolution is coming and soon they'll have a chance to even the score. Eat the rich and all that.

But then what?

Violence only begets more violence. 

I weep for the soul of our society.


The Bear (2025-06-30)

You find yourself in a startlingly familiar position.

What could be more familiar than the grocery store?

As you lazily saunter through the aisles,

a thought crosses your mind

"I should treat myself"

"Well sure," you respond

"That's what the cherries are going to be for."


But suddenly, the simple cherry doesn't sound so great

You feel a deep, painful, feeling starting to grow

Yeah, a box a crackers and a tub of cream cheese would be pretty great

But you told yourself you were going to eat healthier

And now you're stuck,

frozen in the middle of the grocery store


You know this feeling well, a constant companion

The inner pain bubbling up within

You know what it wants (FOOD)

You know that it only stops while you're eating

once you're done, it starts back up again

Night after night, the same battles waged and lost.

But today it finds you in the middle of a shopping trip


You empty your mind,

take a deep breath

1

2

4

exhale

the relief is fleeting. 

You're starting to panic

"I thought I was going to face my demons"

but instead you find yourself facing a 50% off sale


A hand reaches out, and once the tub is in your grasp

all your worries melt away.

A great silence

You're going to treat yourself tonight.

I do blame myself for my eating habits, of course. No one else could possibly be responsible. Yet, I can't help but feel that we have constructed a society where the masses (which apparently includes myself) are mined for profit by large food corporations. To put it plainly, if I was still a kid, there's no way I'd get away with eating half the shit I do. My  mom would keep me in  line. However, I am tragically in charge of feeding myself now. There's just no way for natural food to compete with the cornucopia o f factory-made delights flowing from the large corporations. Hilariously, we sit here amidst an obesity crisis, injecting ourselves with gila monster toxins, in order to stave off the pounds.  I can tell you that if all I had available to eat was fresh, seasonal vegetables, fruits, and whole grains then I would not have the cravings that I deal with.  But then again, maybe I'd be an alcoholic or something. Who knows.
