Comment: Re:Do Not Want (Score 1) 329

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.

So what were you thinking?

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.

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?

Your intrepid reported, reporting from 1910...

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!

Yes, that's what I was thinking too.

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.
