Intersting Facts About The Great Pyramid

The Great Pyramid may be the most interesting and intriguing object on our planet. Here is a link that covers some fascinating facts.

Back to School at the Kahn Academy

Salman Kahn has made over 1,000 educational videos and posted them on YouTube. The topics are chemistry, physics, biology, math, and even finance. This is a great resource for anyone needing a science tune-up or for a student who needs a different perspective. I'm impressed.

No Stimulus for NASA

It appears that about 23,000 NASA employees will be getting pink slips after the end of the Space Shuttle program later this year. I wonder if the Russians will have a hike in ticket prices for hitching a ride to the International Space Station? If the private sector can't get it done in a short period of time, the US manned space program may not be able to recover for a long time, if ever.

39 Days To Mars

Given all the coming cutbacks in manned spaceflight for NASA, there is a new option that could put Mars within reach in most of our life times. Franklin Chang-Diaz and his VASIMR rocket engine are starting to get some notice.

Astronaut Harrison Schmitt on Climate Change

Here is an opinion by Astronaut Harrison Schmitt on how we should manage climate change. Not only is he a former astronaut, but he was a member of the U.S. Senate for a term. I met Dr. Schmitt on two different occasions. One was after a lecture when I was studying chemistry at Henderson St. University. It was just a year or two after his trip to the Moon. The second time was after a lecture in the Geology Dept. at the University of Tennessee in 2002. Schmitt was the only true scientist (geologist) in the early groups of astronauts for NASA.

Wafer-Thin Plastic Stores Electricity

Researchers in the UK have developed a wafer-thin piece of plastic (actually a supercapacitor) that will eventually replace batteries, even in hybrid automobiles. Think of what this could do for personal electronics.
