Science: “An Exercise in Finding What’s True”
Neil de Grasse Tyson’s video below is a must watch. His quote that “Science in an entire exercise in finding what is true”, is similar to another quote that I’ve often repeated from Richard Feynman: “Science is what we do to keep from lying to ourselves.” Watch the video and then share it.

POTUS To Introduce COSMOS Two Sunday Night
I hear that the President will introduce the first episode. I saw this quote from Carl Sagan on Google Plus last week, and it is more true now than when wrote it. There does seem to be a growing segment in America that looks as ignorance as an attractive lifestyle choice. A far cry from the days of Gemini and Apollo as I was growing up. In those days, Texas …

Carl Sagan Passed Away 16 Years Ago Today
Sagan may be gone, but he is now inspiring a whole new generation. His Pale Blue Dot has now been seen by millions who were not even alive when he died 16 years ago today. There are literally thousands of scientists who were inspired by Sagan. After watching COSMOS, his amazing PBS series, I knew I wanted to study science. The fantastic discoveries being made in astrophysics and Astronomy today …

Voyager 1 Approaching The Last Exit On The Solar Systems Highway To The Stars
Voyager One was launched the Fall I started the undergraduate Meteorology program at the Univ. of Oklahoma (September 1977), and the fact that it is still working is pretty amazing. As the video above shows, it is reaching the edge of the Sun’s influence and within a few years it will enter interstellar space where it will remain for the eons. Project scientists this week announced that they are now …

Italy Still Hasn’t Learned
Italy has a history of locking up scientists that say things they don’t like. Just ask Galileo. I wonder if they realize the incalculable damage they have done to their country today. They did it by convicting six scientists whose research on the risk of earthquakes they completely misunderstood. The first thing any college level science student should learn is that any measurement observation or forecast is MEANINGLESS unless it is also accompanied with a measure of the uncertainty. …

Curiosity is 5 Days From Mars
Dr. Ryan Anderson, my fellow blogger here at the AGU Blogosphere, is an expert on the geology of the crater where Curiosity will land. I will be reposting some of his blogs, but be sure to bookmark his blog, and check frequently for updates. This is going to be one of NASA’s biggest triumphs.

Can You Say Nobel Prize?
I knew you could! Seen on Facebook from Sagan Series : “Hairless primates on a wet salty rock discover a fundamental particle.”

The World’s Water- An amazing image.
This image courtesy of the USGS: Some interesting facts I looked up regarding water: Virtually all of that blue blob is salt water and not drinkable. Only 2.5% of that blue marble of water s fresh and 70% of that 2.5% is frozen ice in Greenland, Antarctica, or on high mountaintops. Only .007% of Earth’s water is easily accessible for humans, a fact that I made much of when taught …

Happy Earth Day!
I do not think Earth Day should be about feeling guilty over how poorly we’ve treated our planet. It should be about celebrating the accomplishments we’ve made. I spotted this image from the Sierra Club today, we are making progress toward cleaning up our air and water. Education IS the answer, and science can offer solutions. Earth Day cannot pass without me posting Sagan. Just in case there …
