I was telling my mom about this hair gain shampoo, but i didn't remember what it was called. Then, last night I had a dream i was at the supermarket and I saw the shampoo on the shelf and it's label was rogaine, which was the shampoo i couldn't remember the day before. How did I know it in the dream if i didnt know it before?

What’s your opinion as to these points?

Unfortunately, the human race is predisposed to failure. Here are just three of the reasons why.

1) The human race is predisposed to procrastination which means that we will never try to fix something until it's "in our face". Even then, it has to be "absolutely" proven that it is recognizably affecting our "quality of life" before we will act. For example, take the environmental situation. We still have people (generally for economic reasons) fighting the preponderance of scientific data that indicates we better do something to fix the environment. They seem to think that if they are justified in doing nothing as long as they can find "any little piece of data" which "may" indicate that global warming isn't occurring. Let me ask you this; is it better to act and later discover that the situation was not as "dire" as we suspected or to do nothing and later discover that it's too late to fix???

2) We are naturally territorial (yes, like many other creatures). The problem is that the "sticks & stones" (which were replaced by fire, spears, arrows, gunpowder, etc.) we used to kill the challengers to "our territory" in the beginning have evolved into biological and nuclear weapons with the capability to poison the planet. By the way, how does territory get "claimed" anyway? I mean, at some point in the past nobody "owned" any property but now we all think we have the right to "own" that which was never "BOUGHT". BTW, yes, I "own" land and a house but I still stand by my point that neither the former owner nor I actually ever have had or currently have the rights to buy and sell it.

3) We have worldwide leadership that for the most part is either ignorant or indifferent to the truth (or, in the case of the U.S., BOTH). Without leadership, we will never make any headway and, regrettably, I believe that there are too many governments that are more concerned with either staying ahead of or catching up to, everyone else and are willing to accept the consequences of future problems in order reap the "rewards" of today.

Maybe, if we get lucky, we’ll get a “mini” version of the movie “The day after tomorrow” that will force the world into action. Unfortunately, according to the director of the NASA Goddard Institute for Space Studies in New York, James Hansen (as well as many other scientists), we have 10 or less yrs to turn it around and I don’t think we will. That’s why my wife and I have decided not to bring another life into a world that has more of a negative outlook now than it ever has. Enjoy life and live for the now because too many governments, and many corporations, are steadfast in their path to destroying the future.

I'm interested to learn how plants adapts with different enviroment. Do plants in this condition tipically has small leaves/big stem/branches root? How about in the environment of low sunlight for comparison?

All the "asteroid attention" goes toward one of the large rocks hitting earth...Actually it is more likely that one will hit the moon...as it is, the moon has already taken a lot of hits that the earth may have other wise.
Much of life depends on lunar phases and the moon's gravity. Would we all die, or adapt if this happened

The human body inputs data from several senses (sight, sound, smell, taste and touch) through several organs (eyes, ears, nose, tongue and skin) which are converted to electrical signals and then sent to the brain via nerves for processing into information.

Assuming science progresses sufficiently in the future such that artificial signals could be generated and input directly into the brain to make it believe it was receiving genuine (sight, sound, small, taste and touch) signals, thereby creating a realistic virtual world for the human, who could be a terminally ill elderly person but believe they were a youthful happy healthy person under such virtual simulation.

There have been a number of these questions out here, so I just wanted to give people a chance to get some points.

Easier: If you have n scales (balances) and can use each once. And you have a bunch of rocks that look the same but one has a piece of gold in it and weighs more. What is the maximum number of rocks you can have and still find the gold in n weighs?

Harder: If you don't know if the gold weighs more or less, what is the maximum number of rocks that you can have and still be able to find the gold in n weighs?

Hilbert's hotel has an infinite number of rooms and is currently empty. An infinite number of busses, each with an infinite number of passengers pulls up to the hotel. Each passenger wants their own room. How can you arrange the passengers so that each one gets their own room?

(by infinite number, I'm referring to alef-null, just as a technical note)

When Burt Rutan and his company Scaled Composites took the X-Prize for reaching space in a privately funded and launched vehicle, they appeared to put NASA on notice that private enterprise may very well have the better solution to space travel. Now there is another prize similar to the X-Prize to challenge private citizens to develop alternative plans for reaching the moon. With all the difficulties NASA has had over the past decade with funding issues, a looming deficit, and constant congressional debates over the worth of an ongoing space program, is it possible that private enterprise will be the next ones to develop a vehicle, launch it to the moon, and land man on the moon again? More important still, is it possible commercial development of the moon wil move beyond discussion in science fiction books to a reality we will actually see?

From where do elements heavier than oxygen originate?

Why do we say that materials in our world are mostly "empty space?"

Ok stay with me on this one for a minute while I try and explain.

If we take a telescope with amazingly good magnification and then work out when and where the big bang happened then we will know by the speed of light exactly how far the light will have traveled from the start of the big bang.

If we travel to some point just outside of where the light has not yet reached and use our super powerful telescope to look into the now aproaching light then would we be able to see in the distance the universe bieng created as the light reaches our telescope?

Using the same calculations if we viewed from a closer position of a few million light years then could we see the human race bieng born?

I know there is not curent technology available for this but maybe in the future?

I mean, extreme temperatures existed long into man's existance. Yet we still had to wear clothes. The oldest human found was wearing clothes. Humans have died in extreme temperatures even as far back as then. Maybe this is a stupid question, but what are your thoughts?
