85 Fun Facts from Science and Nature

This assortment of facts comes primarily from science and nature, though tidbits from history, current events, and pop culture do appear from time to time, along with some original fiction. The only common theme throughout - they pique my interest and curiosity. I hope you enjoy them as well. I will try to post something new from time to time, so please check in now and then, or better still, follow me on twitter or facebook. Feedback and suggestions are welcome.

I am leading off with a gem, the energy of the sun. It's paltry, about the same as a resting salamander. How then does the sun produce so much heat? If you are a first-time visitor, you can start here, then step through the articles forward in chronological order. If you are a frequent visitor, and you have already read most of these articles, then jump to the most recent, and step backwards backwards through the archive to pick up any stories you might have missed. Or simply choose from the menu at the left.

Don't plow through all the articles in one sitting, that spoils the fun. Read one every couple of days; that gives you time to process each article before diving into the next one. Some articles are part of a sequence, and are best read in order.

You will notice that some articles use metric units, and some articles use English units, and some even use both. I apologize for this inconsistency. I want my articles to be readable by a wide audience, thus distance should be measured in feet and temperature in Fahrenheit. At the same time, I would like to steer my country gently towardes the metric system, thus distance should be measured in meters and temperature in Celsius. Obviously these two goals are antithetic. My compromise is to use metric when I think I can get away with it, and English units when I deem it necessary for readability within the United States. Neil deGrasse Tyson does the same in his Cosmos series, using metric most of the time, but occasionally referring to miles or feet for familiarity.

The writings herein comprise more than just impersonal, objective scientific facts. They include opinion, anecdotes, observations, and experiences. I hope these make the articles more interesting and more readable, provided the reader can easily distinguish fact from opinion, which I believe he can by context.

Please let me know if you can help me turn these articles into professional youtube presentations, or an e-book, or a printed book. I hope to publish a printer friendly version, without ads, once I reach 100 articles. Thank you.
