A Blast (of Gas) from the Past

Imagine you’re a Trogdorian, living on the planet Trogdor seventy-five light years from Earth. It is ninety million years ago, and your planet has just developed the technology to survey nearby worlds for signs of life.

You train your ultra-sensitive space telescope on a pretty solar system with a yellow star and eight smaller worlds stretched out like gemstones on a necklace. One of these worlds, third from its star, lies at a distance where liquid water might exist on its surface. Intrigued, you set your spectroscope to examine the atmosphere (if any) of this orbiting rock.

Science and Truth

There’s one rather cynical way of looking at science that goes something like this: everything in science eventually turns out to be wrong.

You can understand where such thoughts originate. Once, the best scientists in the world told us that space and time were separate. Then along came Einstein to show how they were linked. Scientists once thought that continents had always existed right where they are today. Then Eugene Wegener showed that continents drift across the globe. Once we thought atoms were indivisible. Then along came a whole zoo of particles that stream out of atoms every time we hit them hard enough. Maybe, this line of thought goes, science just describes what we can see today. When we can see more (with better telescopes, better microscopes, and so on), science will tell us something totally different.

Cars that Drive Themselves

People love their cars. But driving can be risky. When it comes to moving at 100 kilometers per hour, the laws of physics are not always on our side. Stopping a car, slowing it down, or changing its direction at high speed can be difficult and dangerous. But there is a solution to the problem of driving: remove the drivers.

River Mile 240 to 220 (approximately)

The first leg of my Scioto River journey took place on April 13, a sunny, cool day that was perfect weather for exploring. My friend Joan and I headed up to Kenton, the county seat of Hardin County. I was worried about being able to find the source of the river. It is easy to trace the course of the river upstream from Columbus to Kenton using a DeLorme Altas or Google maps. But west of Kenton the stream is so narrow that it is hard to follow on a map. Topographic maps in 7.5 minute scale show more detail, however, and we found the spot. It turns out a handy sign on Roundhead Township Road 15 marks the spot, as well, so I needn’t have worried.

Scioto River Journey

My intention is to travel the river in sections, documenting and interpreting what I see and experience through a blog hosted by COSI’s website, between April and August 2012.
