Fresh Snow




I recently went on a journey through the Cascade mountains. It was a snowy trip. The snow in the mountains was fresh. There is something about fresh snow that looks different from old snow or late season snow. Why does fresh snow look so magical? Is it because we are not used to seeing it? I suppose that could be, if it is the first snow of the season, and you haven’t seen any for almost a year. Or if like me, you live in an area that rarely gets snow, it will always be novel and magical. Of course, snow can also bring inconvenience and travel headaches (we made it through the mountains okay . . . slowly) but I will save that discussion for another day.

However, fresh snow has something else going for it. It has a chance to gradually accumulate on the branches of trees or bushes. Even bare branches can develop a seemingly impossible stack of snow that balances on the slenderest of shafts. Older snow after it has been around a while, begins to clump up and fall off making for a patchier appearance, whereas fresh snow makes the foliage look more like a Christmas cookie that has been professionally frosted.

This got me thinking about how snow might look on other worlds. Of all the many solid surface bodies in our solar system, including moons, asteroids, and planets, not very many of them produce snow. On our world the snow is made of water, H2O. But on Pluto the snow is made of methane. Mars has two kinds of snow, water and carbon dioxide. Saturn’s moon Enceladus has geysers that spew liquid water and ammonia, some of which returns to the surface as snow. Another of Saturn’s moons, Titan, has clouds of methane that sometimes precipitate as snow. Io is one of Jupiter’s moons that is constantly stretched and pulled by the tidal effects of being so close to Jupiter. This causes sulfur geysers to erupt and some of that sulfur returns to Io as yellow snow (quit snickering). Neptune’s moon Triton has pink snow that is made of nitrogen and methane. That is about as much snow that we know of in our solar system.

Of course, there are potentially billions of planets and moons in our galaxy with probably billions of variations of conditions. That is too much for the human imagination to conceive. So, for now I will have to be content to be enchanted by our fresh snow.

Empathy

  Websters defines Empathy as: “the action of understanding, being aware of, being sensitive to, and vicariously experiencing the feelings, thoughts, and experience of another.” Empathy is what makes us human, though lord knows there are many humans who don’t seem to have any. A person without empathy is like a caveman, only concerned for himself. Selfish. It is a lack of community and by extension, a lack of the need for civilization. The person who lacks empathy can have a bit of community, but only with others exactly like himself. It seems like societies go through cycles of empathy and less empathy. Sometimes a single event can change the course of society. Prior to America’s involvement in WWII, the general feeling in America was not very empathetic. We had our own problems. We were still dealing with the lingering effects of the Great Depression, and had been for years. That kind of stress makes it hard to think of others. Hitler was slashing through Europe. He and his fol...

All That We See or Seem by Ken Liu

My first experience with cyberpunk as a genre of science fiction was Neuromancer by William Gibson. Neuromancer was one of the early works that defined the cyberpunk genre. It was insanely influential. It won the Hugo Award, the Nebula Award, the Philip K. Dick Award. But for me, it just did not resonate. I had a hard time visualizing the concepts. It left a bad taste in my mouth for cyberpunk. I mostly avoided the genre. Then a couple of years ago I read Snow Crash by Neal Stephenson which is cyberpunk (although some people say it is a parody of cyberpunk). Whatever, I liked it. I recently picked up All That We See or Seem by Ken Liu and it immediately became apparent to me that this was cyberpunk. Julia Z is the main character, and I think this is going to be the start of a series following her. She is a hacker (hence cyberpunk). She has got herself in trouble and so she lives on the margins, barely making it. Then a lawyer asks her for her help. His wife has been kidnapped. The ...

Polar Bears and Entropy

  Extinction is a normal part of the evolution of life on our planet. You and I and all individual organisms eventually die. That is the way of things. Entropy happens. Entropy is a word from the third law of thermodynamics that basically means: things fall apart. The natural tendency is for things to become less orderly as time goes on: things break down, things erode, things rust, things wear out. Entropy is a measurement of how fast that is happening in any given system. Individual death is a natural outcome of entropy.   But an extinction is where all the members of a species are no longer living. Millions of species have gone extinct over the lifetime of our planet. There are natural background extinctions that happen continually. But sometimes there are events that trigger mass extinctions, where vast masses of species go extinct all at once (all at once in geologic terms, which might mean over the course of hundreds of years). There have been 5 mass extinctions over ...
