On the day that the last space shuttle climbs through the Florida skies, this is an especially poignant video to post. I cannot help but wonder if historians 75 years from now will mark this day as the end of the American century. A century of innovation and exploration unmatched in history. Let’s hope not, but either way man will continue to explore the unknown, because we are the most …

Kudos to Dan Meyer- well worth watching this video. A tip of the hat to TEDx Huntsville for it. We must change the way we teach math in this country or we will face a 21st century of rapid decline. As far as math education goes, we are already well on our way. If you are a student needing some help in math class, I highly recommend khanacademy.org.

This is one excellent video essay by an experienced science journalist. Why the media screws up science. So true, and it should be required watching for reporters.

I did a blog post on Khan Academy the other day, and how he is teaching math to thousands of kids, but Jacob Barnett is one kid who does not need to watch any of Sal Khan’s videos. He could actually do a few for him! If you’re a college student in Calculus 2 and are having trouble with integration by parts or trig substitution, then you may want to …

I found Khan Academy by accident. I was reading a paper on climate science and realised that I poorly understood a concept in statistics, so. I googled it and found khanacademy.org. I’ve been hooked ever since ,and if you know a student who is struggling in maths, show them the web site immediately. If you did lousy in high school or college maths, (and want to understand it better) then show yourself Khan …

An EF-2 tornado hit Theodore, Alabama on Wednesday and caused significant damage. The tornado was rated an EF-2 by meteorologists at the local NWS office in Mobile, and that indicates wind speeds of 180-218 km/hr (110-135 mph). The image below shows the track of the tornado. Notice the hardware store in the image (between the two EF-2 triangles). There were several security cameras running at the time the tornado hit …

BBC News – Brian Cox: Science is not ‘dominated by old men’.

Here is a video produced by BP about the Gulf Coast Beaches. They claim in the video that the sand is clean, but this appears to be untrue. First, the very slickly-produced BP video: Now a video from a local resident. Tar balls as far as the eye can see. The difference is he can’t afford to put his view on TV. BP can. A much different story it seems. …

Many network news stories I’ve seen on climate change end with an interview of someone who has never published anything in the field repeating an often heard myth. The myth almost always has long ago been shown to totally wrong, so it gets a new life. ABC News (U.S. not ABC Australia) aired an excellent, and scientifically accurate piece last night on the flooding around the world over the past …
