The Tautochrone Curve

No matter where a ball is placed on the curve, it will roll to the bottom in the same amount of time.

The curve is called the tautochrone, and it is an inverted cycloid.  A cycloid is the line traced out by a point on a rolling circle. 

Christiaan Huygens discovered this remarkable property of the cycloid in 1659.

They should name an interplanetary exploration craft after him.

The only thing cooler than Kepler continuing the search for exoplanets is the clever way they're making up for the lost reaction wheels.
 
Kepler May Go Planet-Hunting Again! Infographic Shows How That Would Work

The planet-seeking Kepler space telescope had to stop its primary mission this summer after the failure of a second of its four reaction wheels, the devices that keep it pointing at a spot in the constellation Cygnus. NASA, however, has a backup plan. It’s considering stabilizing the spacecraft using the sun! You can see the details in this infographic.

Aspiring spies take note: a refrigerator is not an effective Faraday cage.
 
Refrigerator as a Faraday Cage?  Not so much.  A cocktail shaker on the other hand....

The worst part is when you ask about your grade and he says, "I'm so sorry..."

"We all have too much information and not the faintest idea how to intelligently aggregate it and use it within our political systems. We need a scientific approach to institutional design. Trial and error is an archaic procedure that takes time that we don’t have, and errors have become too costly."

Great picture. I love the log scale.
 
Voyager 1 has entered interstellar space, no really, the scientists agree this time unlike the several previous announcements. See where it is in this diagram. Note the scale in the diagram - each tick is 10 times farther than the last and units are AU - the Earth-Sun distance.  Interstellar space in this case is a particles and fields definition, e.g., where the Sun's solar wind no longer dominates.  Voyager 1 will take another 30,000 years or so to leave the space dominated by the Sun's gravity (e.g., to get out of the mostly gravitationally bound Oort cloud).

We have five children and I'm proud of every one. The oldest is a sophomore in college this year and the youngest is in preschool.
