I have a hard time staying focused on lectures unless I'm taking notes. There really is something about this process that helps me to focus and organize the material. If I find myself in a class where I'm scribbling as fast as I can just to keep up, it's pretty much hopeless as I've lost the thread of the lecture and the notes will be of no use. Professors need to better organize lectures so this doesn't happen.
Another thing, the professor may choose to cover material that isn't in the textbook, so notes can be essential then.
If you accelerate very fast in 1 years time you'll be in interstellar space without any materials for building a home. Same in 2 years. Same in 3 years. In fact, because of the physical and relativistic limits you won't arrive anywhere in a humans lifetime. Your spaceship will be your new home.
Perhaps your grand-kids might live to start a home on a new planet though.
All sci-fi that I've read/seen is fiction in the science part too. What have you seen that isn't?
Perhaps you mean plausible? Was Star Trek plausible? Star Wars? At this point inter-stellar travel is science fiction, but it may be plausible to think we'll get there.
No, this isn't a geosynchronous satellite where the ping time would be on the order of a second, the altitude of these LEO satellites is only 620 miles. Ping times would be short -- the ping times from the East to West coast of the US would be much higher.
Man, none of you guys have a clue. Have you read Rand or are you just regurgitating what you read on Wikipedia?
Rand's philosophy isn't about wealth, it's about expecting a fair reward for your inspiration and sweat.
Money isn't something that is simply printed out by the government; it’s the output of a man's mind and back. It isn't a zero sum game. if you think smarter or work harder you should do well. Those who do not think or work don't produce anything and can't do well -- unless they steal it from those who do. The world is a better place because of those who think and work.
According to this philosophy those who do well aren't necessarily rich they can be anyone from all walks of like.
On the other hand, the Karl Marx philosophy is about theft. Those who need take precedent over those who produce. There are so many demonstrations of the failure of this system that it's a laugh to see it even discussed here.
So you would actually take out the guy trying to save lives in the hope you would like a little longer? I guess that makes you a coward or the worst sort.
It's clearly a hoax, at least in the implication that the cart can sustain faster than wind travel.
The propeller is capturing wind energy while the cart is moving slower than the wind. Later that energy is used to temporarily propel the cart faster than the wind. Note that in the video they stop the cart immediately after they get to top speed.
Another thing to consider -- while the cart is moving near wind speed there may be other effects (air turbulence) that cause the flags to move opposite the direction of travel.
Obviously, if the cart were moving faster than the wind, then in it's reference frame the wind would be going against it. How can you get positive acceleration from a negative force?
Many people are reporting the growing difficulty of navigating their horses and buggies through the town streets due to the growing presence of noisy and fast moving motor cars made by Henry Ford. Predictions are that because of this obnoxious growth in motor cards that our highways will become completely unusable within 10 years!
I suspect it may have something to do with North Korea being in the news so much and then confusion about the whole North/South thing among much of the population.
Another problem is that the bees aren't constrained to follow our roads, which are non-direct. Based on the distance travelled and the turns made, the bee can quickly deduce there must be a shorter path and then just fly a more direct route. This won't work for a salesman because he may take what he believes to be a shorter road and find that it’s actually longer. Because of these path limitations the travelling salesman problem is a more difficult to solve.
Yes, you and Hugo Chavez are right, we should all pay alot more for our consumer goods. Food and clothing should be local and expensive (and rare)./sarc
Well, how about you're wrong!
Carbon Dioxide is already dense enough in the atmosphere that it blocks about all of the outgoing radiation that it could possibly block, adding more CO2 only amounts to lowering the level in the atmosphere where the radiation is blocked. So a doubling of CO2 will only make a slight blip in the temperature. That much is settled science and what happens after that is where it gets complicated.
The warmists say that as a result of this slight CO2 induced warming other resulting changes produce a positive feedback that will cause a dramatic rise in temperatures while the skeptics contend that isn't so. And that is the part that is NOT settled science.
"On their deathbed, no one wishes they had worked more."
I suppose you're right about that, but there are probably many who wish they accomplished more.
"Wait 'til the next recession wipes out 70% of your 401k. If you've been around long enough, you got wiped out in 1987, then again in 2001, and then again in 2009. "
Your making some poor choices with your 401K. I've lived through those market ups-and-downs and I usually just see them as a buying opprotunity. Keep your monthly investments going and don't think about them (much) until retirement and you'll be doing better than 90% of everyone else out there.

No, taxes are NOT low. In 2009 the US took in over $2.3 trillion in taxes. In who's distorted world view is that low?

I assumed that if the Doc was smart enough to figure out time travel he could also figure out how to put the car in the right spot.
Yes, that's what I was thinking too.

I see, so how many parallel energy production system are you proposing? Doesn't that sound expensive/counterproductive/silly?
Personally I don't really see what the issue is as long as they're just watching your mouse cursor on their pages.
Of course, but your depending on Google to limit it's use.
For me, I've switched to another search engine.

For now, the new batteries can power only NANO devices. There, fixed that for you ;-)
Your car isn't 100% reliable either but you still use it.
My ipod nano doesn't run apps.
