Actually, if you had taken that $30k for the Volvo and instead invested in Tesla stock, you could now afford a Tesla and keep your original $30k investment.

It's amusing to think about: By letting Tesla borrow $30k for a few months, they reward you with one of their cars.

Which happens to also (statisitically speaking) increase your lifespan by reducing the odds that you'll die in a car accident.

As an applied physicist wanting a better grasp of the mathematics I use, I'm working through Mathematics of Classical and Quantum Physics by Byron and Fuller. It's a Dover book, so it's inexpensive, and so far it has been enlightening. For instance, it uses the example of vortexes in a swirling bucket of water to help visualize the curl of a vector field.

Automated Creation Technologies is a startup company that provides open source tools and services related to 3D production technologies. They will have a booth at the upcoming Maker Faire in Austin, TX this weekend, so you can stop by, check it out, and take a 3D printer home with you that day!"

Submission + - A robotic jewelry polishing system

Roland Piquepaille writes: "If you live in Rapid City, South Dakota, and if you bring one of your old rings to a jewelry shop for cleaning, it's highly possible that the job might be done by a robotic jeweler. An engineer at the South Dakota School of Mines and Technology (SDSMT) has built and brought to market a robotic system which can pick up a ring, polish and grind the ring, and replace the ring in its original tray before picking up the next ring. And of course, it's able to do this faster than a human being: it can function about three times faster than a human operator when configured as a grinder and about four times faster when configured as a pre-polisher. Read more for additional detailss and pictures of this robotic jeweler in action."
