One of my homework problems

"You are a consultant for a new Star Trek movie. You were hired to make sure that any science in the movie is correct (We will not discuss tachyon bursts and sub space and/or temporal anomalies!). In the script , the crew of the Enterprise (NCC 1701 E, repaired after the encounter with Shinzon of Remus in Nemesis) discovers an abandoned space station in deep space far from any stars. This station, which was built by Earth in the 21 st century, is a large wheel-like structure where people live and work in the rim. In order to create "artificial gravity", the space station rotates on it’s axis. Captain Picard asks chief engineer Geordi La’Forge to figure out at what rate (angular speed) a space station 195 meters in diameter would have to rotate to create "gravity" equal to 0.7 that of Earth."

Notice the only information I actually need to solve the problem is in just the very last sentence. I think my physics professor is kind of a geek.

Summary of Conversation

Disclaimer: Pointless rambling ahead. Satisfaction not guaranteed. No refunds for time spent. Accuracy also not guaranteed. It is 3:30am and I don’t know what I’m talking about.

Science and religion both try to form explanations for things that happen in our universe. Since you can’t trust anything besides first-hand experience, how do you know what to believe?

Physics supposedly has set laws, and humans only discover them. However, I disagree with this. We observe our world and discover consistencies, and create laws based on those. The problem is, physics doesn’t always follow the rules. Sure it likes being consistent most of the time for convenience and aesthetics? but this is the reason there are still unexplained phenomena and exceptions to these man-made “laws”.

Time isn’t constant.

Acceleration is caused by an imbalance of forces.

The only thing we know about history (or the present, for that matter, at any place besides where we currently are) is what we are told. So we are forced to put our faith in other people. We can verify math or laws of physics on our own, but we can’t verify history.

Should history be recorded? There must be a proper balance in the way it is recorded between the amount of detail/specificity in the record, and the record’s longevity and decipherability. Video is undoubtedly the best way to record history, but it (or other digital/film recordings) might become obsolete and may not be compatible with future technology. Print writing or pictures will last longer. Pictures are more vague and prone to less clarity than written records, but what happens if a language becomes extinct? The picture would be more likely to be understood, while the written record may or may not be decipherable. Oral records can’t be destroyed, in a sense. They can however become altered or misinterpreted throughout many generations.

Technology is advancing at a frighteningly exponential rate. Consider technological advancements during the following ranges of years:

  • 3000 BCE - 1000 CE (4000 years): fire, wheel, language, swords/armor
  • 1000 CE - 1900 CE (900 years): printing press, gunpowder, railroad, electricity
  • 1900 CE - 2000 CE (100 years): airplane, color/audio film, atomic bomb, computer/internet
  • 2000 CE - 2010 (10 years): social network, smartphones, terabytes, 3G

We have gone from horse-and-cart moving along at 30mph to machines that fly through the sky at 2000mph carrying 1000x as much cargo, and we have gone from pointy sticks that can injure a man’s arm to a lump of metal that can incinerate an entire island in a matter of seconds. From traveling for months across the continent to relay a message, to communicating with one another on opposite sides of the world instantaneously. Revolutions are being organized overnight. The world’s getting faster and more dangerous.

As was mentioned before, acceleration is caused by an imbalance of forces. Perhaps the world just needs more balance. Or perhaps the acceleration is caused by something else. Human curiosity perhaps? Are we just becoming more curious? Or is it simply that the more we discover and learn, the easier it is to learn and discover more?

The only thing to do is wait and see what happens. There’s no getting off of this rollercoaster.

Oh late night conversations about religion and science, one of my favorite pastimes. (not even sarcasm)
