Get hypnotized by this wave pendulum … seriously, I can’t look away.
A wave pendulum like this is built of equally weighted objects suspended by different (and carefully calculated) lengths of string. Released simultaneously, their differing periods (frequencies of oscillation) cause them to form a “wave” image together that cycles through all possible patterns.
It’s mind-boggling. Looking for a science fair project? This would be a great one.

i’ve got goosebumps.
Last weekend, the last shuttle went on its last mission ever.
The shuttle Endeavour went from Los Angeles International Airport to the California Science Center last weekend. The trip took two days as NASA engineers working with utility crews, police and other personnel moved the shuttle through the streets of the city of angles.
With the parking of this shuttle, so ends the 30 year mission of the shuttle program. The end of an era of regular, United States-led space travel. The success of the shuttle program is so well known and the image of the shuttle so iconic, it’s almost surreal to see it sharing the same screen as Randy’s Donuts or Roscoe’s chicken and waffles.
This time lapse video of the shuttle’s journey is moving and jaw-dropping. I don’t often say this, but if you watch only one online video this week, it should be this one.
