Q
Attn Highly Technical: The Ten dimensions explained

Someone in a 2nd dimension world (which is impossible for us to really imagine) wouldn't have a concept as time as we know it. You're taking time for granted as always being...time! This explanation is saying that the 4th dimension is what we call time, because the 4th dimension is a "line"- a...

Q
Automobile Environmentalism: Hybrid vs. Combustion

That's pretty interesting. That's probably the oldest data we can get, since the Prius was pretty much the first widely manufactured hybrid. It's nice to see that it has lasted five years w/o any problems. My Highlander is a 2006 (almost a year old,) and it's driven mostly on backroads in New...

Q
Automobile Environmentalism: Hybrid vs. Combustion

Yeah, the benefits are a-many. The reason the government and other organizations are providing these added benefits to hybrid drivers is to promote an incentive to clean up the environment. I can't wait for Boston to approve free parking for hybrids! Then I don't have to worry about those...

Attn Highly Technical: The Ten dimensions explained

Well, yeah. We 3rd dimensioners find it extremely difficult to fathom what other dimensions would be like to be in...because we only really know our own. I don't think there are better metaphorical connections you could make besides the one demonstrated in the animation. There's an extremely...

Q
Automobile Environmentalism: Hybrid vs. Combustion

Yes. The regenerative breaking is another source (a pretty good source) of extra energy for the electric motor, other than the gas motor supplying the electric motor when efficiency allows the process to be worth it. Regenerative braking came in after the first hybrids were being produced, as...

Very cool. I've always had a bit of trouble with these concepts, but the animation/great narration made it much easier. Well, I had to watch it twice, but still! Thnaks for posting this!

photosynthasis: how

6 CO2 + 6 H2O + light ? C6H12O6 + 6 O2 Carbon Dioxide + Water + Light energy ? Glucose + Oxygen They take in carbon dioxide, water and light energy, do their crazy stuff (did an enourmous study on exactly how these reactions work, and it's quite a process) and the result is glucose, which...

Antimatter doesn't exist on Earth except very briefly and in very small quantities during processes like radioactive decay.

I know this may sound silly. But, why has no one cured the common cold?

That's pretty much right on. There is an enourmous amount of viruses with similar effects (runny nose, sneezing, coughing, etc.) If you get one and don't die, you become immune to that specific one. But there are hundreds, maybe thousands and those little guys tend to mutate. Mutate a lot faster...

Q
Automobile Environmentalism: Hybrid vs. Combustion

You've missed an extremely simple, but important aspect here. "Modern mass-produced hybrids, prolong the charge on their batteries by capturing kinetic energy via regenerative braking." The battery starts out with a charge, just like with a combustion-only vehicle (but of course they don't use...

Zero to the zeroth power

Um...I think the point is that the calculator simply defines 0^0 as 1 if it ever comes across it, because any other definition would screw things up where it shouldn't. Forget the ti-89. If a supercomputer tried to do the same thing, it would have the same problems we are having. 0 is weird- it...

The "intelligence" of evolution

I think that evolution would seem to/demonstrates characteristics of intelligence, but this by no means makes it intelligent. I think we're confusing it with the natural tendency for more beneficial traits to be expressed more frequently over time. Which is just Natural Selection. Like I...

Zero to the zeroth power

Did you fail to notice that after entering that in, on the bottom it reads "Warning: 0^0 replaced by 1?" Anyway, I'd say that from what we've seen here we can call the expression 0^0 indeterminate.

Q
My science teacher's idea

Yes. IF you could convert a mass into its eqivilent energy, you would get a lot of it. But that's not an easy task, is it? If we could produce antimatter in those quantities and keep it under control, time travel would (theoretically) be a snap: The relationship between energy and mass can be...

Q
Automobile Environmentalism: Hybrid vs. Combustion

The point of hybrid cars isn't that it saves energy, because yes, the electricity in the batteries came from fossil fuels as well. It's mostly the reduced emissions, and the regenerative braking is great too (and it sounds pretty sweet, if you've heard it before.) Also, the computers that...

This makes a lot of sense, and was what I was thinking of while I read the other posts. It really depends on where you're using it: "Exponentiation: x^0 = 1, except that the case x = 0 may be left undefined in some contexts. For all positive real x, 0^x = 0." Further, x^0 for any negative...

Q
The "intelligence" of evolution

I don't think it's quite this simple. Well, that and I'm not sure what you're trying to say (possibly because I'm wicked tired...) There are probably multiple genes that came into play here, besides beak type. You'll notice that now, the finches from different parts of the islands can have quite...

Q
The "intelligence" of evolution

An excellent example of evolution and speciation is the infamous Darwin's Galapagos Finches. On the Galapogas islands, there are 13 different species of finch. They are extremely similar in size, shape, color, etc etc. However, each species has a very unique beak. Each of the finches can be...

The moon, you and a little red button

Yes DrPizza, you're right. A "yotta" of something is 10^24 of something. A yottaton of something is 10^24 tons. I very dumb. Thanks, Hamzter, for doing the work that everyone else was too lazy to do. Those're some pretty funny conclusions you have there.

The "intelligence" of evolution

Uh oh...definition squabbles! Microevolution and macroevolution both refer to the same thing: a change in allele frequencies over time. It's just that macroevolution is commonly associated with speciation, because it takes place over periods of microevolution. The only argument/dispute...

*Sigh.* People on forums get mad when you make reference to one of their posts while disagreeing with them, even if not directly (no matter how ambiguous the disagreement may be, and in this case it most certainly was.) The fact of the matter is that we KNOW what causes traffic jams (as we've...

Haha a "yottaton" is simply 10^24 of SOMETHING. What do you mean by this? 39 yottatons of...what? Granite? TNT? Chamomile tea? Did you just learn the word or something? For example, 1000 yottatons of marshmallow probably wouldn't put the moon out of orbit. But that would be pretty funny. It...
