Another interesting property of the logarithmic spiral is revealed if you roll it along a horizontal line. This animation shows the curves traced by points on the spiral, and note that the very centre follows the path of a straight line. The angle between this line and the horizontal is called the pitch of the spiral, and for our spiral galaxy the pitch is around 12 degrees. [more] [code

When is the last time you saw the Milky Way? Or have you never really seen it like this? I grew up in a rural area and I took it for granted. Now I live near a large city and I have to drive at least an hour to see it. I always look forward to that drive. I hope you will all find a way to see it. It’s getting more difficult with all the light pollution out there, but I hope you can do it. #astronomy #astrophotography #milkyway #space #stars #universe #galaxy #canon #oriontelescopes

Another way to present the 9 types of intelligence as exemplified by my How Do We Measure Intelligence post.

The basic idea is that different people are good at different things. These 9 probably don’t cover the wide range of smarts we all possess, but it’s a start.

As Albert Einstein said, ”Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”

The double pendulum is chaotic: the behaviour of the system is extremely sensitive even to small perturbations. Notice for instance how the two pendulums in the animation start at almost the same position, but their motion drastically drifts apart soon.

New device allows brain to bypass spinal cord, move paralyzed limbs

For the first time ever, a paralyzed man can move his fingers and hand with his own thoughts thanks to a new device. A 23-year-old quadriplegic is the first patient to use Neurobridge, an electronic neural bypass for spinal cord injuries that reconnects the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb.
