The 156 Best Episodes of Star Trek

As promised I've gone through the data from IMDB for all the Star Trek series, and found the best episodes across all the series.  I took the top 25% of episodes in each series and combined them.  Then I cut it off to only those episodes that had a rating of 8 or above, which only cut off a dozen or so episodes.  Here are the episodes, sorted by series and then air date.  I'd add you should probably watch any two part episodes, even if they aren't listed, because they are usually both good and important to the plot.  In DS9 the ending arc begins with S7E16, and even though some didn't make the cut, skipping any of those would be madness.

I've previously written some overviews of each series, so maybe couple that with this.

Michael Jackson's Moonwalker for Sega Genesis

https://www.youtube.com/watch?v=-N68qvYFpTA

I watched someone play this for about an hour last night.  Keep in mind that this is a real game, made with Michael Jackson's consent. 

It involves him collecting children (from trunks of cars among other places), his monkey bubbles jumping on his head and guiding him, and an inexplicable Conan O'Brian-esque celebrity mouth bit.

Replacing a bad hardwired speaker cable with a jack

I have a pair of Logitech X-230 computer speakers that have served me well for close to 10 years now.  One issue is that the cable that runs from the speakers to the computer is hardwired in.  Recently, a wire failed and I was left with mono sound.  While this was fine for fireside chats, music sounds much better in stereophonic sound.

I decided to open up the speaker and see how feasible adding a jack would be.  The layout was simple enough.  I identified where the wires connected to the circuit board and used a multimeter to determine which wire went to which part of the plug (tip, ring, bottom).  I labeled the circuit board with my findings.

I then closed up the speaker and debated what to do.  I could have easily just spliced in a new wire.  The problem was I didn't like the idea of ruining a new wire, and I liked the idea of a jack for future flexibility.

The problem was I hadn't soldering in 10 years, and even then I had no idea what I was doing.  I decided to learn how to solder and attempt this as a first project.

I was making a large electronics purchase from Sparkfun, and so included a soldering iron and 3.5 mm stereo jack in the order.

If you read the comments on that jack they are pretty bad.  The only other choice at Sparkfun was this jack.  Note that the first one is panel mount which meant it had a nut to hold it in a hole drilled in a panel.  The second one would have to be held in place internally somehow.

This animatronic parot gave its life
so I could listen to Manowar

I watched a lot of soldering tutorials, and read some stuff.  Then I found some solid wire from some old network cable I had, as well as some stranded wire from an old talking parrot toy I had.  I made some splices and soldered them.  With that I declared myself the world's foremost authority on soldering *.

The first order of business was removing the hot glue holding the audio cable in place.  Following some internet advice I used some acetone and it released the cable immediately.

I cut the cable giving myself about 8 inches to work with inside the speaker.  I tested the part that would remain inside the speaker to make sure the broken wire wasn't in there.  I also stripped the ends of the other part so that I could use it for testing.

A quick note, there are three wires in a stereo audio cable.  Right and left channel, and then a common ground.  The ground is often bare wire twisted around the outside of the other two wires which serves as a shield.  I just twisted up that part of the ground wire, with no regard for interference inside the speaker.

Now I had to install the jack.  I drilled a hole in the side of the casing and put the jack in.  However, as the comments had forewarned, the jack was not deep enough to fit through the wall.  Actually it was just about perfect depth to fit, but with no space left over for the nut.

I thought about gluing it in place, but ended up drilling a slightly larger hole and then by pure luck having the nut fit perfectly in there.  I then could screw in the jack to the nut.  Once it was screwed in it was pretty much locked in place.  This meant I had to do the soldering inside the speaker.

For some reason only the ground tab had a hole to thread the wire through.  I probably should have drilled holes for the other two.  It took about 3 hours to solder the wires on.  Including soldering the first one on the wrong tab and then having to unsolder and then resolder it.  The angle of the case made it very difficult to get the iron in a good position.  The ground and another tab were quite close and I kept getting bridges between them.  The ground wire with its holey tab took about 10 minutes.

I did a final test with the multimeter to make sure there were good connections from the solder points on the circuit board all the way to the bare ends of the audio cable.

I closed everything up and just about had a heart attack when an audio test revealed the left and right channels to be mixed up.  Then I remembered that I don't care about the channels being correct, and as a result the speakers are physically on the wrong sides.

I must say the end result is about a billion times more professional looking than it should be.

Secret soldering expert?

* Note "the world" is the name I call my house.  Even then this is a tenuous claim, as I believe my cat may have substantially more soldering knowledge than it is letting on.

IMDB Ratings

They are remastering Star Trek TNG and releasing them on bluray.  They just released season 3 and I was looking through them.  One of the first things that I noticed was how many great episodes were in that season.  Seasons 1 and 2 had some good episodes, but it felt like most of the season 3 ones were great.

This wasn't that surprising; I've often stated that in each Star Trek series the first two seasons tend to be the worst.  As I constantly feel the need to evangelize Star Trek I wanted to see what the top episodes were and list them here.  I found that the IMDB had individual user ratings for each episode.  I almost didn't notice they had a simple page with all the ratings on there and was about to write a script to scrape them from the season pages.

I copied that data and began to work on ways to present it.  I wrote some gnuplot scripts for a few graphs.  I wanted to ultimately make graphs for each of the five series.  The problem was preparing the data for each plot was rather time consuming.  I decided to write a perl script to do that.

The script went well, and I decided I was on roll so I might as well make it download the data itself.  I ended up with likely my most robust script ever.  Every show has a IMDB id like: tt0092455.  You can either put that in the file, or pass it to the script as an argument.  It generates a directory for each show, and puts all the raw data files in there, along with 3 graphs.  I suppose I could have made it so that it takes multiple ids and runs each, but it's so easy to just paste them into a file and just type 'perl imdb.pl ' down the column and save that as a shell script.

I'm pretty happy with the script.  It handled the real word data of a variety of shows quite well.  Which is frankly amazing considering this regex is in it:
$fileline =~ m/\s+(\d+)\.(\d+)\s+(.+?)\s+(\d+\.\d+)\s+(\d+,?\d*)\n/

Here's the script, and the source for the 0 of you that are interested.

I ended up compiling a list of 32 shows, both my own favorites and popular ones from the internet.  Here is a gallery of all the graphs.

http://imgur.com/a/gO68p

This one is a straight forward scatter plot of every episode.  There is a linear regression line plotted showing the general trend.  Note that in all the graphs the seasons fall entirely to the right of the grid line they are labeled at.  In other words the first episode of season 5 is directly on that dotted line, the rest of season 5 is to the right.

The average rating of each season.  Not weighted by number of reviews.  Also note that none of these graphs start the y axis at 0, which exaggerates difference between points.

Here I took the top quarter of best episodes and bottom quarter of worst episodes and counted how many of each were in each season.


I still will have to do some comparison between the Star Trek series and post that.

Chaos Theory

I wrote this overview of chaos theory for a class, and figured I'd post it here.  It's written for the audience of my professor, but you can gloss over the more technical parts.  The first half is mostly a historical overview.


Chaos is a condition where a deterministic system, governed by a set of simple rules, can lead to erratic, seemingly random results.  This is because tiny variations in the starting conditions are amplified many times and become significant.  While this may seem like a logical thing, it was only recently discovered and accepted.  The history of science is about discovering the laws that govern the natural world, and it was long accepted that simple laws lead to simple consequences.  The idea of chaos as an innate property of natural systems was so revolutionary that even its discoverer avoided the idea.

Chaos theory was discovered largely by accident.  The story begins with the ancient Greek philosophers who came up with the term chaos as a contrast to cosmos, their name for order in the universe.  The word chaos meant an empty abyss that existed before creation.  The term was used at the start of the Bible which is translated to "without form and void" to describe the state of the universe before God created the world, and with it order.

In the late 16th century, Galileo developed his laws of motion.  These laws seemed to govern all the motion in the world.  This set off a series of discoveries of simple laws that explained a wide range of phenomena.  Galileo was followed by Kepler who came up with laws that very accurately described orbital mechanics.  Kepler described orbits as ellipses that had the planets speed up as they moved in closer to the Sun.  After Kepler, Newton arrived and drew the connection between earthly phenomenon and the heavenly movements of planets.  His insight was that the same set of laws described all motion.  The same force that pulled an object to the ground on Earth kept the Moon in orbit in space.

Newton also cast the die for all modern science.  He invented calculus as a tool to help explain the constant change that governs nature.  He came up with a differential equation that described all motion:
`F = ma = m cdot {dv}/{dt} = m cdot {d^2s}/{dt^2}`
where: `F` is force, `m` is mass, `a` is acceleration, `v` is velocity, `s` is displacement, and `t` is time.

Newton's few simple laws described the vast array of motion observed.  His technique of finding a differential equation to describe a system, and then integrating it was the prototype for science for hundreds of years.  With this technique scientists could predict future states based on known initial conditions.  Following Newton's lead gave rise to whole new fields: Fluid mechanics, elasticity theory, kinetic theory, thermodynamics, and electricity & magnetism are all examples of fields that resulted from Newton's way of doing science.

Newton published his blueprint for science, the Principia Mathematica, in 1687.  For the next 200 years it described all motion observed in the universe.  However, in the late 19th century flaws with Newtonian physics began to emerge.  One flaw was the fact that light could only exist as a propagation of a wave.  Yet, Newtonian physics said that on observer riding at the speed of light should see light standing still, but still oscillating as a wave.  Einstein explained this paradox by developing special relativity.  Special relativity said that time and length are relative, and not unchanging as dictated by Newton.  This was the first of three major challenges to Newton's world view of absolute laws.

The second challenge came from the study of electrons in the atom.  It was shown that electrons could only exist in discrete orbits.  When the electron changed from one orbit to another it made a quantum leap, never existing in the space between.  While these two revolutions took place early on in the 20th century, the third took longer to be accepted.

The story of the third revolution begins with the same orbital mechanics that were so instrumental in creating Newtonian physics to begin with.  Describing the orbit of one body around another is known as the two body problem.  The differential equation describing it was solved by Newton by converting it from a nonlinear to a linear problem.

The similar problem involving three bodies was, however, unsolved for many years.  Mathematicians eventually simplified the three body problem into a problem with two large bodies in a circular orbit, and a small particle-like third body.  This was known as the restricted circular three body problem.  Unfortunately, even the simplified problem proved intractable.

In the late 19th century a mathematician and physicist named Henri Poincaré attempted a novel, and largely geometric, solution to the three body problem.  He invented a concept called state space.  A state was all the information one needed to calculate the future of a system.  State space was the collection of all possible states.  Using state space, Poincaré could map a system and study its behavior from a fresh perspective.  Additionally, Newton's differential equation, F=ma, gives a vector field in state space.  This vector fields shows what an object at any given location will do from there.  By following the vector arrows one can start an object in state space and follow its path to learn how it will behave.

Poincaré attempted to plot the three body problem through state space but discovered a shocking revelation.  He found that the paths of the bodies crossed each other infinitely many times.  This meant that a given starting location had two possible paths that would lead to very different behaviors.  Which path a body would take depended on tiny variations in the exact starting location.  Here was a deterministic system where tiny changes to the initial conditions would lead to wildly different behaviors, the first glimpse of chaos.

Chaos theory is inherently interdisciplinary, and has seen application to a wide array of different problems in unrelated fields.  Fractals are a well known visualization of chaos.  The Mandelbrot set is the most well known fractal.  The rules for generating it are simple.  Begin with the complex number plane.  For any given complex number c in the plane, follow the iteration:
z_n+1 = z_n² + c, with z₀ = 0.  If this sequence remains bounded then c is a member of the Mandelbrot set.  By coloring the Mandelbrot set black against a white background one can see a border of infinite complexity.  Zooming in on any portion of the border only shows more complexity.  The difference between a number falling inside or outside the Mandelbrot set is infinitely small.

Fractals also show another sign of chaos.  When zooming in on the border, the same patterns appear at every level.  The same distinctive Mandelbrot shape is visible no matter how far one zooms in.  The same is true of other areas where chaos governs systems.  Graphs of heart rate variations and Internet traffic flow show the same overall pattern when one zooms in, a result of chaos.

The double pendulum is another simple example of chaos in action.  A pendulum is described exactly by Newton's F=ma.  Given the position and velocity of a pendulum one can predict exactly how it will behave in time.  Adding a second pendulum to the end of the first, however, brings chaos into the problem and makes it intractable.  When started from a high position, the double pendulum behaves erratically, with the second pendulum swinging around the first seemingly at random.  However, the double pendulum is governed by the same F=ma as the single variety.  It is simply a result of chaos that tiny imperceptible differences in the starting conditions lead to wildly different behaviors.

Another example of the practical benefits of chaos are cryptographic hashes which are used in storing passwords, and just about every other use of cryptography in computers.  Cryptographic hashes take a piece of data as an input and then output a small, random, but deterministic, key.  In effect, they give a fingerprint to data.  To be useful, they must have something called the avalanche effect, which says that any tiny change to the input should result in a large change to the output.  Changing a single bit in the input data will result in a totally different hash.  This allows hashes to serve as proof that data hasn't been tampered with.

Chaos theory had a long journey from a mythical concept, to something that was deemed to only represent the unknown aspects of nature, to an accepted innate quality of the universe.  The man considered to be the discoverer of chaos in its modern form, Poincaré, found the idea so shocking that he largely ignored it.  It was decades before his discovery would begin to turn up useful results.  However, it is now indisputable that chaos is a fact of nature.  Further, it is indisputable that chaos theory has been invaluable, having applications from weather prediction to computer security.  It deserves its title of the third revolution of the 20th century.

President Obama Can Shut Guantanamo Whenever He Wants

http://www.slate.com/articles/news_and_politics/view_from_chicago/2013/05/president_obama_can_shut_guantanamo_whenever_he_wants_to.html

If Obama declared hostilities at an end, the Guantanamo detainees would be no different from people who were washed up on U.S. territory by accident, like shipwrecked sailors. Those who pose no danger to the United States (about 86 of the 166), and cannot be returned to their countries, could receive refugee status under existing laws. Those who are known to be dangerous could be arrested under criminal law. If I am correct that section 1027 is unconstitutional, both groups could be brought to the United States. The detainees we cannot convict would be released. That may be politically unpalatable but it is legally unimpeachable.
