Comment Know how to do things others don't. (Score 1) 1086

The question is not whether you'll spend all of your time applying math. The question is whether there will come a time where strong math knowledge will help you solve problems which others cannot solve. There are any number of specialties which this applies to. Do you really need parsing abilities? Database abilities? Filesystem abilities? Network abilities? Image-processing? No, of course not - except that if you have them, you will find them helpful at unexpected times.

Unfortunately, it is usually not the case that someone will be weak in a subject AND they will still be able to identify that their skills are not up to the problem. Rather, what usually happens is they just keep hacking away, oblivious to what they're missing, spewing bugs in all directions.

Actually, IIRC theres good reason NOT to believe that there is a war. As I recall there are several clues point to the fact that there simply isnt any war, and that the entire thing is a hoax to keep the people under control.

I agree, that's how it feels when you read the book. But if true - why switch enemies periodically, only to cover it up later and deny it ever happened? The system would work just fine, and even save some trouble (altering records and disappearing people), if the enemy was always Eurasia.

Totally. It would also be easier to just say 2+2==4, it's more obvious than having to say it is equal to 5.

In many cases, public schools would do better if they *did* think of themselves as a daycare with an educational component. Right now it seems in vogue to imagine schools as sort of mini-universities, treating the kids as little informed consumers (at best - at worse, the kids are treated like waldos remotely operated by their parents. I never could figure out how teachers expected me to change minor quirks in my child's school-time behavior). But, well, even motivated and curious 3rd graders simply don't have the attention span to learn for more than a half hour at a time. For young kids, things like gym, art, and music are not nice-to-have once-a-week extras, they are sanity-preserving essentials that should be used to break up the day.

But, well, I don't think it's clear that the US public school system is about educating future Americans. It's about being a huge political football.

And yet ... with all that awesome technical know-how, we were unable to replace it with a next-gen manned launch vehicle before end-of-lifing it.

I'm not saying your wrong about knowledge bit-rot, but it is entirely possible that the vast experience we had developed was hindering future developments rather than helping them. It's also likely that expecting coherent development from a political program is expecting too much.

Comment Re:Ball Lenses are fun! (Score 1) 139

Also, speaking of ball lenses... you can use your head as a ball lens to extend the range of your car's wireless entry key fob. If you find yourself just out of range of your keys, simply put the transmitter about an inch behind your head, directly *opposite* the car. Your head is mostly transparent to the RF, but has a slightly different index of refraction from air/vaccum, thus acts as a lens. And since your head is approximately spherical, it works well enough to make a practical convergent lens.

Odd, I've always heard it as that you hold the fob under your chin.

The article quotes a supporter:

"But on Monday, Senate floor sponsor Sen. Mark Madsen, R-Eagle Mountain, said in some states children are being indoctrinated in socialism via some curriculum."

They're making an entire law without backing up their statements over there, I bet that will have more ramifications than an editorializing slashdot submitter.

Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

I totally want them to make a Footfall movie and really use a Project Orion craft. Usually they just have a technobabble solution for how the humans beat the aliens, but in that case you didn't need to use technobabble. The humans really did have a big stick, they were going to kick your ass, and there wasn't anything you were going to be doing about it.
