A Picture Worth a Thousand Words

Micahel Tobis, over at Only In It For The Gold, is always a worthy read. Today, he had the image below in a post: For a much more detailed answer, the go to person is Michael Pollan. Here are two article Dr. Pollan wrote for the NY Times. http://www.nytimes.com/2009/09/10/opinion/10pollan.html The second one is best but much longer. It will make your jaw drop.

What Really Crashed At Roswell

Roswell in New Mexico has made itself into the tourism mecca for those who believe we have been/are being visited by aliens. Thousands attend the annual UFO festival and just look at the artwork on the chamber of commerce web site! Countless TV shows with eyewitnesses and so called experts have looked into the reports that a flying saucer crashed into the desert near Roswell in July of 1947. It …

How Much Radiation Does it Take to Kill You?

It’s an interesting question isn’t it? Something you should probably know.  A little bit if information that you HOPE you never NEED to know. As my sister once said, “Once you’ve seen one nuclear war, you’ve seen’em all!” In general people are afraid of radiation, and that is a good thing. It can be dangerous. It can also kill off a cancer that is eating you up. It can, and …

Sunset From the Saturn 5 Rocket Cam

There is only one upright model of a Saturn V Moon Rocket. It’s right here in Huntsville, and it’s next to the first Saturn V ever built. (The real one is in a building to protect it!). The rocket that took man to the Moon is 363 feet high. That’s 36 stories. It’s one of only three remaining, and is a priceless object of history. For my readers in other states, …

NASA's Most Difficult and Perhaps Most Important Shuttle Mission

When I was young, if you were an Astronaut, you were famous. Everyone knew what you looked like. Not so anymore. The public fascination with space waned after the Moon landing and it has not recovered. These days, the only way an Astronaut gets famous, is if he dies or gets caught in a sordid love triangle. Astronauts are not household names anymore. Some of the reasons for this may be the …

Thomas Midgley RIP (If you can)

You probably have never heard of Thomas Midgley, but believe me he has impacted your life. He was a graduate of Cornell University and worked as an industrial chemist for his entire career. His first big invention was to make an additive for gasoline that almost completely eliminated knocking in car engines. The additive was made of tetra ethyl lead. If you are my age, or older, you can remember …

The Curious Case of Pioneer 10

Dr. John Anderson of the Jet Propulsion Laboratory has discovered something very weird. Two other colleagues have been working on it as well. As of now, there is no explanation. Safe to say it’s likely keeping them up at night! Not that they haven’t tried to figure it out! Sherlock Holmes said, that once you rule out the impossible, then what remains, however improbable, must be the truth. The truth, in this case …

The Most Distant Man Made Machine

When I hear a scientist, talking about some astronomical object, and they say something is (for example) 8 billion miles away, I cringe. No doubt, the reporter asked for the distance in miles, or kilometers, because that unit of distance is familiar to most people. Does it really tell you anything? I say no. Yes, it tells you it is very far away, but nothing much more than that. To really understand these distances, …
