Read this interesting article about the two crew members who reunited after 40 years with the once super-secret spy plane, number 17958 Blackbird SR-71, that put them in the history books.
What amazing achievement it was! All possible through physics, chemistry, mathematics, engineering, etc. The article has a nice video as well. In case the article becomes unavailable, you can download the text here as a pdf file (1,6MB).
On the 4th of June 2005, I was fortunate to see a Blackbird SR-71 (picture on the left) in the Steven F. Udvar-Hazy Center of the Smithsonian National Air and Space Museum in Washington, DC. In the distant background, behind the Blackbird, one of Nasa's space shuttles, is visible. If you are interested to see more about this Blackbird, click this link.

Presentation on beams
Videos in which beams, shear forces and bending moments are discussed are available for our grade 10 technical science teachers. They will be informed how to get hold of the videos.
The presentation used in the videos is available here and the questions (plus one extra) are available here. Feedback is welcome; either as comments below this post or send me an email. Look at the left side of the home page, near the top, for the email address.

We as teachers should make children believe in themselves
I stumbled across this story about Thomas Edison on a blog called All things beautiful. The moral of the story is to make children believe in themselves; that is what we as teachers should do! Here is the story.
One day, Thomas Edison came home and gave a paper to his mother. He told her, "My teacher gave this paper to me and told me to only give it to my mother."
His mother’s eyes were tearful as she read the letter out loud to her child: "Your son is a genius. This school is too small for him and doesn't have enough good teachers for training him. Please teach him yourself."
After many, many years, Edison's mother died, and he had become one of the greatest inventors of the century. One day he began looking through old family things. Suddenly he saw a folded paper in the corner of a drawer in a desk. He took it and opened it up. On the paper was written: "Your son is addled [mentally ill]. We won't let him come to school any more."
Edison cried for hours and then he wrote in his diary: "Thomas Alva Edison was an addled child that, by a hero mother, became the genius of the century."

Changing these bad perceptions is crucial!
The bad perceptions about the state of our science education: We have to change it! Here are four articles dealing with the perceptions:
- South Africa finishes last in WEF’s 2016 mathematics and science education ranking (7 July 2016)
- South African mathematics, science education ranked worst in the world (15 April 2015)
- South Africa stone last in Mathematics, Science education ranking (3 September 2014)
- Truth about SA’s mathematics, science education quality (5 June 2014)
