Digital Time Capsul

For a while now I've tried to think of a secure way to store information in such a way that no one (including governments, companies, and the guy who made the information in the first place) could retrieve the information until a set date. The only way I can think to do this would be in the very sho...

Re: 0893: "65 Years"

Species who made this "irrational" choice to visit other worlds must've had a technological level way above our own. A civilization can't survive in space. Sure we can visit, but we can't move. That's not space technology we're lacking, that's the technology required to have a fully functi...

Hmmm.
Slightly curved screen... four buttons on the bottom..
Might this be a Nexus S?

What phone does Randall have, do we know?
I know he used to have a G1 so he's definitely an android man.

question about windows/linux systems for businesses

In my university we have computer labs. Anyone with an account on the server can log into one of these and no matter which one they log into they are greeted by all of their own files and settings etc. That means when they log on, they're not actually logging on to the local system, but another, lar...

There's more to programming that someone's not telling me.

So I learned how to program. Leaned the basic C/C++ built-in functions. Learned how to use other people's libraries to make GUI's or do other nifty things. So I can see how 98% of programs are written. But how on earth do people write code that modifies the OS? Take DeskPins for example. It's a smal...

Need cool physics experiment ideas

Ok, so for our senior college physics lab class our prof told us to design our own experiment to measure something. We only have 2 weeks to do this, so it's not supposed to be that hard, but we can do pretty much anything we want. I want to do something awesome.

Ideas?

I learned recently that the threshold of pain for the human ear is 10^13 times the threshold of hearing. (http://hyperphysics.phy-astr.gsu.edu/hbase/sound/earsens.html) That's an impressive range, and it's about the same for the human eye. When I mentioned this to my friend she commented on how biol...

I have found AIM, Skype, and Google Video Chat to all be unreliable and prone to grainy/stuttery video/audio regardless of what computer I'm using and what type of broadband connection I or the other person have. Sometimes they work just fine, but about half my conversation always ends up being abou...

Dodecahedrons. The 3D shapes made up of equal-sided pentagons shaped into a ball. They have the property that you can stack them together and fill all space with no gaps. (just like cubes) Here's what I'm trying to visualize: If you have a gap-less pile of these, how many dodecahedron balls are surr...

Re: Cool: Brain computer interface games.

Hey guys. I actually got one of those force trainer things. I'm still learning how to use it. I want to know exactly what waves it's picking up and what they each correspond to. I've never used my mind to control any thing before so I'm not very good at it. Any one know where to learn more details?

I'm sure people have done studies of which numbers are most likely picked in 1 out of 10 and 1 out of 100. Does anyone know of one?
I heard that people like to pick prime numbers more often than random.

Re: Relative Velocity/Energy Question

The kinetic energy in a system depends on what frame you are viewing it in. In one frame the KE is 1/2 m1 V^2 and in the other 1/2 m2 V^2. This isn't any kind of contradiction, Physics works in both frames exactly how you would expect it to. (try imagining the masses bouncing off one another or inte...
