Does the 2nd law of thermodynamics apply to more?

September 16th, 2011 — 9:56pm

The 2nd law basically states that the entropy of a system never decreases or remains constant. Or rather it can never become more organized, or less disordered.

Yet nature has been churning out more and more complex organisms for the past few billion years, so what’s going on here? How can a system (in a slightly different sense of the word) become more complex? How can humans have evolved from simple bacteria? Wouldn’t it make sense that humans would be devolving?

Nature does amazing things. When you look at the genomes of both humans and simple bacteria, you find something amazing. Even though humans are far more evolved, their DNA has been shrinking in a sense. There’s some single celled organisms with genome sizes far larger than the human genome. I believe this is because nature is obeying the 2nd law. It’s continually decreasing disorder.

The first organism to gain a genome, most likely some exotic form of a single celled guy or a virus, probably had built a genome much, much larger than currently exists. The vast majority of the DNA didn’t do a thing, not because it didn’t code for anything, but because the cell didn’t have anything to do with it. It hadn’t yet built the necessary organelles and enzymes. It was the simplest of everything.

The cell began to increase in complexity. The only way to do this, without violating the laws of the universe, is to allow the DNA to increase entropy. This is where the magic happens. When the cell increases entropy, or increases disorder, it subsequently increases efficiency. What better way to progress evolution? Abide by laws that should break systems down, whilst secretly building more complex machines. All by accident. They’re rebels, in a way.

It makes perfect sense too. Imagine the possibilities that could stem from random mutations throughout a near infinite number of organisms over the past 4 billion years. Combine this with DNA uptake systems and suddenly you have a rapidly evolving, however random, set of organisms. All fighting the second law of thermodynamics, mostly losing, but the lucky ones survive to reproduce and push the species forward.

Do this long enough and you wind up with a human. The pinnacle of evolution.The organism destined to get to know the universe.

Brains…

July 7th, 2011 — 10:43pm

I was reluctant in choosing a suitable title for this post…

When I watch my dog or cat navigate through the house with perfect precision, I can’t help but wonder. What’s going on inside their heads? I’ve narrowed it down to two possibilites. It’s either muscle memory from countless repetitions or they have the ability to draw the floor plan in their minds, similar to humans. But even for me, it’s tough to produce a two dimensional picture of the floor plan of a house in my mind. Instead, I can visually think my way through. I can imagine that I’m walking out of my room and taking a left down the hallway, where I take a right into the living room. I pass the couch to my left, with artwork to my right. I can’t tell you the number of steps I need to take, but I can think it through in my mind. I believe the animals are doing the exact same thing.

I’m a somewhat experienced hunter, having been sitting in the woods every season since I was just 10 years old. I’ve come to know a fair amount about the patterns of the animals, most notably deer. They have intricate trail systems spanning for miles upon miles through the woods. Trails that the average person wouldn’t even recognize as they’re so complex. Yet the deer don’t just make new trails whenever, they follow the existing ones. We frequently create new trails with our 8 wheeler out through the swamps. We do it every two years or so, to keep the vegetation in a constant cycle so we don’t destroy the land. Every time we create a new trail, there is countless deer sign (prints, rubs, scrapes, poop) up and down it. They’ll follow the trail, probably because it’s just easy walking, but it’s the fact that they use the trails that caught my curiosity.

If we don’t create a new trail, neither do they (assuming that there aren’t any other significant changes to the woods). So here’s miles of trails that the deer systematically, and predictably, follow throughout the year. They’re not randomly walking these trails, which means that they have to be doing the exact same thing that we do when we walk the floor plan of our house.

It makes sense that other animals would be able to do such similar things with their mind. It’s necessary for survival. Imagine the animals that couldn’t remember their way back to safety. Don’t you think natural selection would have killed these off very early? Of course.

I think that the difference between their minds and ours is very little. If anything, it was only our body that enabled us to rise to where we are today. Had we not developed the capabilities to vocalize, use our opposable thumbs, etc. our brains would be little use to us. Passing down the acquired knowledge and skills would be infinitely harder (although we frequently see this, for instance in crows which was recently discussed at TED). It’s almost as if our brain is capable of nearly anything, it’s just waiting for the necessary mechanical pieces to finish the puzzle. Evidence of this might be shown in the latest experiments with animals and humans controlling computers using thoughts. The monkey with the robotic arm is exceptionally eye-opening. So isn’t it possible that the brain size is directly proportional to the complexity of the body? Obviously, as you look at various animals their respective brains change in size with their body size.

My apologies if this is dated or debunked. I’m just thinking out loud.

Imagine if we could freely transverse time

June 18th, 2011 — 8:53pm

We can move forwards, backwards, left, right, up, and down. But imagine if we could move those three dimensions? Instead of moving within those dimensions, what if we could just pick them up and move them. We already do this, we’re doing it right now. We’re all doing it at relatively the same rate. The faster we travel through those three dimensions, the faster we move those dimensions. So if we’re just sitting still on the Earth, we’re moving those dimensions at the same speed as someone who’s walking down the street; this is because the differences are extremely negligible. Though imagine the astronauts that are rocketing through space. They’re moving the three dimensions at a somewhat faster rate than we are.

When you move those three dimensions, you are traveling through time.

Time travel is nothing more than the moving of dimensions. The real question lies in whether or not we are capable of moving those dimensions backwards. After all, time travel into the future is extremely easy. You simply have to travel extremely fast. In other words, you simply have to move very quickly through the usual three dimensions in order to notice a change in the fourth dimension. So hop on a space ship traveling close to the speed of light, travel around the the solar system, and come back and you’ll have effectively traveled forward in time. For instance, if you spent 1 hour on the space ship traveling at the speed of light, something in the order of thousands of years would have passed on Earth. Similarly, if you were able to stand on the edge of a black hole, without being crushed into an infinitesimally small point of matter, you could also experience a massively large movement of the fourth dimension.

Why deleting my facebook was one of the best things I’ve ever done

June 17th, 2011 — 9:11pm

I never realized how much time I spent staring into the deep abyss that we call Facebook. I literally always had it open in one tab of Chrome, I had the app on my iPhone, and I got notifications, texts, and emails all day long. It controlled my life, and there’s no moderating it! Sure, you can tone down the number of emails you get, but as soon as someone posts to your wall, messages you, etc. you have to log in to see. Then you spend an hour stalking old flings, looking at childhood photos, playing games, and writing rather inane and cryptic messages on your friend’s walls. Following my brother in law, I went cold turkey and deleted that bad boy. I never looked back since.

With all of my new found free time, I’ve accomplished a lot of cool things. I’m opening a new business on the West Coast, I had time to work on ChuckFish.com, and I got to spend a lot of my spare time learning new things. I read through a few books. Here was my last reading list:

Social Engineering

A brilliant read on the inner-workings of the human mind and how people behave within society. It dives deep into the black arts of manipulation and related concepts. It’s tough to describe, but I recommend it if you’re interested in people/psychology.

Alpha Dogs

A great book on how small business owners stayed small, yet grew to become market leaders. Features a bicycle shop that does several million to an ice cream shop that lets managers essentially do whatever they want! It’s a neat read following neat businesses.

I read a few other books that weren’t as noteworthy, but at the time of this writing I’m about to open DNA, The secret of life by the one and only James D. Watson.

Engineering Protein Structure from DNA

June 16th, 2011 — 9:58pm

A little thought I had while bear hunting in Canada.

I’m not too sure of the implications of this, nor do I know if there is a need… Hell, I don’t even know if it’s even remotely possible.

Here it goes:

You can take a piece of DNA that codes for a protein. You can then break it down into the specific amino acid. That’s pretty self explanatory. We’ve been doing that for years now. Then you know the specific order of the amino acids. You officially have the primary structure of the protein that is being coded.

Then, using a “cheat sheet” of sorts, you could determine whether the amino acids form an alpha helix or a pleated sheet when they’re linked with hydrogen bonds. You now have the secondary structure. Repeat this process until you determine the tertiary and quaternary structures.

We already know the exact structure of many proteins, so assuming the amino acids follow the same rules when they fold. A comprehensive database can be formed to describe the specific folding, linkage, etc. A simple program could easily render the structure, allowing us to easily view the entire structure. Whether or not this is already being done, I’m not too sure… but I thought it might be neat. Who knows what sort of implications this could have, perhaps it would be the first step in visualizing more complex interactions between proteins, organelles, cells, tissues! Who knows! After all, I do believe that there is a pattern beneath everything and every organism on this planet is just a set of instructions.

More on DNA and the Brain…

June 15th, 2011 — 8:16pm

Since the dawn of computers, scientists have longed to bring intelligence and consciousness to their computers. Countless attempts at beating the turing test, machines that can play chess, natural speech interpreters; it’s all a collection of algorithms written by a human trying to play God. Functions with specific arguments, designed to return an even more specific result. This sort of system can never yield anything other than a pure computation machine.

Biologists hardly understand the systems that make humans tick. It was only recently that “junk DNA” turned out to do something after-all. The electrical signals from the brain can be monitored endlessly, however the neuroscientist still cannot produce a picture of the cognitive canvas. They claim modern marvels by designing robotics that interface with brain, yet the true mystery is the brains elasticity and willingness to accept and control such devices, not their primitive technology.

I believe that computers are bound to go through phases, just as any other technology has done. Much alike the hand mill/steam mill example, the present day computer is not the pinnacle of technology, but merely an extremely basic version of what’s to come. Quantum computing will be the logical next step. The proposed computing power of such a machine would be unparalleled by today’s technology. Quantum computing, however, will be replaced. I believe that the ideal design lies within that of biological processes.

First, we must learn to understand the system. It will start with a primitive organism, such as a bacteria. The genome of the species will be fully documented, and programmable. Geneticists will be able to “code” for new genes, producing miraculous results. DNA will become the ultimate programming language, much like assembly for computers.

Scientists will then learn to utilize such protocols as chemotaxis and photosynthesis, one of the most elementary functions of these bacteria. More about DNA will slowly become understood, and the miracles of birth will be recorded in a clear and concise manor, easily reproduced.

Soon everything regarding biological species will be understood. From the way humans think, to the subtle differences between man and dog.

I believe that geneticists will uncover a higher level programming language embedded within the DNA. I believe that this language is going to be found within the non-coding regions of the genome, which was largely regarded as “junk.” It’s going to be at least a decade before it’s truly understood, and perhaps an additional decade before the conceited scientists realize they made numerous mistakes and misconceptions the first time around.

If computers have taught us anything, it may be that hardware is the structure for which everything is built, but the true innovation lies within the software. Even still, the software may have numerous levels. For instance, everything is ultimately built on a set of processor instructions, which then the operating system interacts, on top of which the programs run. For a system as elastic as the brain, which can lose ½ of it’s mass and still function perfectly, it wouldn’t make much sense that everything would be written in the lowest level language.

The brain structure has to stem from instructions within the DNA. Yet imagine if the coding regions of the DNA are merely construction instructions, while the operating portion resides within the noncoding region. The noncoding region is actually a cryptic structure which defines the very algorithms that control every process within the organism. This would also solve the age old question as to why the DNA of a chimp closely (98.something%) resembles that of a human, and a banana has somewhere around 50 % of similar DNA.  It’s because each organism, regardless of its structure, behaves and acts the exact same. All of this did, theoretically, extend from one single organism way back when… when the first cell adopted viral DNA! They’re all operating on very similar instructions, adding further validity that animals are not so different than you and I. (Assuming you’re human)

Why DNA is like a programming language

February 15th, 2011 — 7:29am

Deoxyribonucleic acid, more commonly known by its acronym DNA, is the fundamental code that makes up the human body, and all other life forms on the Earth. Before I dive into my little analogy, let me give you the specifics on what DNA is.

DNA is a polymer, which is composed of monomers called nucleotides. The nucleotide consists of a 5-carbon sugar, a nitrogen containing base, and a phosphate group. The DNA consists of four different types of nucleotides, which differ only in the nitrogenous base. The four different nucleotides are represented by the letters A, T, C, G which correlate to adenine, thymine, cytosine, and guanine, respectively. The DNA is organized in two complimentary strands, which form a double-helix shape.

Where does this crazy stuff come from? The easy answer is that it comes from the parents of the critter (or you). So your parents each donate half of their DNA, which combine to create a unique offspring.

So this DNA is contained in a ton of places throughout the cell, but generally every cell in the human body contains a copy of your DNA. It’s stored safely inside the nucleus of the cell. So when something needs to be manufactured inside the cell, a little enzyme comes along and unwinds and unzips the DNA into two separate strands. So this is like the source code for humans.

When we look at computer programming, we generally have two classes of programming languages. Compiled and interpreted. Compiled programs are written using a programming language, such as C++, and are run through a compiler to make a functional program. The compiled program can be reverse engineered or decompiled into the original source code. Interpreted code is written just like any other program, however it’s not compiled. It’s interpreted and then returned each and every time it’s executed.

Now back to the cell…

Inside the nucleus we have some DNA, which then needs to get executed, or translated, into a functional protein or enzyme. The DNA runs into an enzyme which then compiles it transcribes it into a piece of RNA which then will eventually directly code for the protein. So the cell is actually maintaining a copy of the original DNA inside its nucleus at all times. This helps decrease the possibility of “accidents” or mutations. DNA acts like a combination of interpreted and compiled code. It is first interpreted which generates the RNA and then compiled into a protein. To perform a task.

So sure, there’s a copy of all the genetic code lying around in every single cell within every single organism but theres also the product of the entire code — everything within the organism that isn’t DNA. Every piece of an organism was coded by DNA, so why can’t we just break down those pieces? Why can’t we decompile them into the code that made them? Wouldn’t that make understanding organisms so much easier? We could decompile each and every enzyme within the human body, and learn how it’s exactly constructed.

There’s a huge difference between reading code and understanding it. Sure, anyone can look at latin and pronounce the words correctly, but you have to have an advanced understanding of the language to get anything out of it. You need to know not how to say the words, but how to understand their meaning. If we can understand not what each piece of DNA makes, but also how it makes it… we would make a quantum leap of which I can’t even begin to fathom.

Adaptive Algorithms

October 17th, 2010 — 8:12pm

A long time ago I had this idea that you could make a piece of software be able to alter itself depending on the input that was provided. I was sitting in a tree-stand hunting deer when this idea came across. This was about 2 years ago.

Anyway, my idea consists of writing code that would perform a certain task. However, should the variables in the input change (we’ll call this the environment) the software would rewrite its functions to accomplish another set of goals that would be predefined. So say the program is passed ‘A’, it then will execute a standard function (the behavior) and return something (we’ll call this the action). So as the environment changes, the behavior is modified to fulfill a set of standards, and thus the action is entirely different.

Now you’re probably wondering where the program would get such an ability to alter its own code to fit all of the infinite possibilities… right? Well you start off small. You give the program some basic instincts to work with. You give it a set of goals for certain environmental inputs, say ‘A’ through ‘G’. What we’ve just created is a piece of software that can adapt to its input and produce a result dependent on its predefined goals.

Obviously, software that is attempting to write its own outcome isn’t going to be very efficient. So we limit the number of possibilities. Say we set some sort of limit as to how long the code has to write its new function, thus making it occur quickly. It can simply run a number of scenarios to determine whether or not the goal is achieved. Simple? I think so.

So we have a very small number of inputs and goals paired a time-restriction. What we do is break all of the results (or the behaviors) down into it’s algorithmic components and set it all aside into a database somewhere. After awhile of collecting data from multiple tests, we can let the software utilize the algorithms it has already used. It would now be super efficient for environmental variables that it has already encountered, thus enabling us to throw more at it.

What we’re left with is a piece of software that can effectively write its own algorithm to complete a task based upon previous outcomes, which is synonymous with thinking and learning.

But hey, it’s just an idea.

Thoughts on Music

October 16th, 2010 — 5:13pm

As I sat in my basement trying to bang my way through some Beethoven, I started to wonder what made his (and other classical composers) music so great.

Now, keep in mind that I am not a musician whatsoever. I have very little musical abilities. I don’t play the piano, guitar, or anything else. I just have a knack for trying to find reason and improvements in other forms of science. Maybe someday something will come of it all.

I pulled the classic “Fur Elise” into some software and made a spectrogram of the piece. It’s colored using a logarithmic function, with linear frequency on the y-axis and time on the x.

Beethoven - Fur Elise

I’m not interested in creating music using math, but what I am interested in is finding out why some music is pleasing to us. Why we find it relaxing or exhilarating… what made the classic composers so great!

I believe that there is a pattern within absolutely everything, especially within nature. Since math is the fundamental language of science and sound can be reduced to math, I’m convinced there’s some correlation.

Why I want to go to dental school

October 13th, 2010 — 4:27pm

I’ve been thinking a lot about this lately. I can’t seem to come up with a solid, concise reason as to why I want to attend Dental School and become a Dentist. Deep down in my heart I know it’s what I want, but my brain doesn’t understand why? Why would anyone want to subject themselves to another 4 (possibly more) years of schooling after 4 years of undergrad? I know the answers are contained deep inside my soul somewhere and I’m going to attempt to figure it out.

[ad#ad-2]

I enjoy helping people

Whenever someone has a problem, I’ll generally listen to what they have to say and attempt to help them if that’s what they’re seeking. If someone needs help working on their car, their house, or anything else that I can be helpful with, I’ll always offer a hand. I like to think of myself as a giving person… though we’re all lazy sometimes, right?

I like people

So there’s plenty of people that I know whom I’m not very fond of whatsoever. Yet there are far more people that I love talking to. I love hearing about what they have to say and I love telling them my stories. The best part about owning Dog & Claw is having the chance to talk to handfuls of people per day; sometimes for extended periods.

I love making people smile

What fun would anything be if no one ever smiled? Imagine a world so cold that everyone was grim and kept to themselves? I want to have fun in my life and I think you should as well! However, some people don’t feel confident with their smile, for whatever reason, and I would find nothing more gratifying than possessing the ability to alleviate them of their insecurity. Watching someone leave my practice while showing their pearly whites would be deeply satisfying.

I’m a family man

So I could become a physician and help people with a plethora of other problems, but it’s just not for me. Dog & Claw has given me a taste of 18 hour work days and I’ll tell you what, it’d get old quick. I envision myself having a job that gives me the financial security I need while allowing me to spend a lot of time with my family. What fun would life be if you didn’t have someone to share it with?

I like technology

Medicine is always improving and I would love nothing more than having the ability to work with some of the newest technology while doing my job. Well that’s a lie, there is one thing I’d love more… developing some of that new technology. Applying everything I’ve learned throughout my life to develop a tool, method, or system to help doctors/dentists perform their job would be wonderful. I like to get my creativity on every once and a while.

Scrubs aren’t so bad either…

I know I could get through dental school. I always rise to the occasion. I’d be focused. I’d be hungry for it. It’s just a matter of whether I can get in or not. I still have a couple years to go with undergrad until I have to “wow” some the AdComs.

Wish me luck?

The story of mankind.

October 12th, 2010 — 5:48pm

Intro

Billions of years ago by mysterious forces deep down inside organic soup, the building blocks of life emerged. The components of life began to clump together to eventually form the very first cell. A single cell that’s smaller than anything you can even fathom. It would be this negligible amount of organic material would form the basis of the most complex life species on the planet. This cell would transform a planet into a home.

As millions of years shot by, life began to evolve. It transformed into new exotic species. It grew into more and more complex forms of life. And most importantly, it diversified. Somewhere along the line these organisms started onto a trend that would produce the most powerful of all species. It started on a path that, according to many minds, would have a definitive ending. This path of life is the only path that would come to a stop. A stop for such a species, yet a beginning for another.

Early hominids begin to walk the earth. They diversify from their relatives, the chimpanzee, by gaining an upright posture. They begin to move out of the trees and onto the ground, causing them to gain arches in their feet. The proportions of their faces are altered, and their muscles adapt to the new living conditions. They are evolving. They are changing to suit their new found environment. And soon a miracle takes place. Early humans invent their first tools, effectively paving the way for mankind as we know it. Humans began to take present day shape.

Their societies begin to evolve as well, yet humans cease to change significantly. The only thing that is changing now, is their intellectual capacity. Though it’s not their intelligence that’s changing, it’s their knowledge. They have reached their full potential. The evolutionary processes are slowing down dramatically, though it has not stopped. These evolutionary changes are caused by natural selection; A force which is present throughout nature that enables the strong to survive and the weak to die. It is a pivotal part of creating a successful species and without it, life would fail to exist.
