Comment Re:If Mr. Buffet really wants to change the world. (Score 1) 224

I agree that we should push forward on all fronts with renewable energy. But Thorium-based LFTR reactors solve most of the problems with nuclear energy, including the two biggest bug bears of them all: nuclear waste and safety. There is practically no waste in LFTR and the fuel is fantastically plentiful compared to Uranium. There are huge Thorium deposits right now. And LFTR reactors are virtually melt-down proof from the get-go. Where uranium reactors "want" to blow up by default, LFTR reactors are amazingly safe. Watch the link and the other Google Tech Day presentations. LFTR reactors have already been tested and they WORK. The military is responsible for taking us down the dead end of using Uranium for power just because it can be used in weapons. LFTR is better technology and can't be used to make bombs. Thorium CAN be the solution for our total energy needs for the foreseeable future, and will be a great adjunct to renewable energy when something like solar finally emerges. You can build lots of solar cells with safe, cheap, clean LFTR power, and then who cares if solar isn't quite as efficient. It can be used in locations that need it most right away.

...and leave a legacy that will improve life in smaller countries, he should champion the development of cheap, abundant, safe nuclear power in the form of the Liquid Flouride Thorium Reactor (LFTR). Thorium is far more abundant than Uranium and the plants are potentially much smaller and cheaper.

Comment Re:Duel on main street at high noon is a MYTH. (Score 2, Interesting) 398

Obviously, dueling with pistols in the 18th and 19th centuries is well known. My point is that the quick drawing hired gun pulled his gun, shot his victim and the whole thing was over in 20 milliseconds. You could have a loaded gun pointed right at him with your finger on the trigger and still lose by a wide margin. Watch the video. Especially that last one.

The truth is that the duel at "high noon" is a myth perpetuated by spaghetti Westerns. An actual quick draw expert can shoot you several times and re-holster his weapon before you even have time to blink. It only takes about 20 milliseconds for them to get a shot off, while human reflex time is typically about 150-300 milliseconds. A real gun slinger could kill you even if you had already drawn your weapon and had your finger on the trigger. With such a person facing off on main street would be laughable.

Comment Re:Arduino is where it's at! (Score 1) 376

Most of the kits you find at Radio Shack are firmly rooted in the 60's and 70's, where the most high tech item in the kit is the venerable old 555 timer and maybe a transistor plus 50 cents worth of resisters and a couple capacitors and an LED or two.

One who dismisses discrete electronics in favor of microcontrollers and other "high tech items" has left the path of enlightenment. At some point, you are going to want to use that microcontroller to actually control something.

Well, diversity is our strength with this approach, grasshopper, because no component is excluded merely because microcontrollers are included. Sing Cumbayà with me because it's actually a good thing that we don't have whip out our 20-year-old copy of CMOS Cookbook anymore to make something useful happen.

Want to interface with a $5 surplus LCD display? No problem with an Arduino. Try that with a 555 timer. Want to interface with a cheap GPS module? No problem with an Arduino. Let's see you do that with discrete components.

Learning electronics is about having fun, and with microcontrollers you can have lots of fun fast. And you don't have to give up making spaceship sounds with a 555 timer, either. You can just add the sounds to your spokePOV and really impress your neighbors (and your kids). :-)

Submission + - High paying jobs in math and science?

An anonymous reader writes: Where are the high paying jobs for those good in math and science at? I've heard about math and science shortages for almost two decades now, and I was wondering what high salary/high demand jobs have resulted from these shortages. Most science majors I know actually make less than teachers (in Texas teachers make $38-40K to start for nine months work). In terms of money, what career would you pursue coming out of college right now with a math or science degree?
