Religion aside, the popular theory is that the universe started with the big bang from a tiny spec of dust that was dense beyond all comprehension.

My question is if everything has a beginning, where did that spec of dust begin? And where did the beginning of what began that spec of dust begin from. I have a hard time comprehending that the Universe and all that's in it just came into existance spontaniously.

Even god would have a beginning, correct? This question makes me dizzy.

Seriously, I had thought often that if and when mankind arrives at the Oort belt, a "shell" of comet-like bodies that orbit earth from way off, they could aim numerous comets at Venus, causing tremendous cataclysms but cooling the planet, and install large solar-reflecting mirrors in orbit around it to produce solar energy on earth while shielding Venus. Enough comets would put seas in Venus's basins. [Maybe they could even "rope" the planet Mercury somehow and put it around Venus for a moon, to create tremendous tidal forces hence an electromagnetic field needed for life to thrive. Mercury is fifty percent greater in diameter than our own moon, and more massive. Or, they could just send a bunch of meteor material in orbit around Venus, eventually creating a moon. Anybody else excited by the idea? Let's do it! [Kidding, but serious.].

A rancher friend of mine asked me this question today and I thought it was too complex for me to answer as I am a carpenter and this does not come up in my line of work:
If a water supply containing 10 acre ft of water is 100 feet above the land to be irrigated and has a slope of 45 degrees, a regulated 12 in pipe is inserted at the bottom of the reservoir as the pipe gets smaller the pressure becomes greater but the volume gets smaller. The question is what is the greatest size pipe at the bottom of the grade that will give 125 psi. the slope is 300 feet long and at the bottom the pipe will be attached to a sprinkler system the pressure cannot exceed 125 psi. This entire system is gravity feed.

Since birds have such extraordinary abilities of navigation, is it a sense like we have for balance that is extended to the point that they can tell which way is North, South, East, West? How do they navigate to the same nesting grounds over such long distances over and over?

I have developed a very detailed model of gravitation that suggests this is the case.

I am a Texas Tech student. When I began my study of engineering, I had dreams of staying stable in a city(not moving from place to place) and solving unique problems. I wanted to create models and run experiments with them. Above all else, I want to design and create actual machines without spending hours on end making hundreds of 2-D drawings for a seemingly small project or having to stare at the drawings of others. I want to work with my hands and my mind, where someone would ask me to create a machine to perform certain tasks and I pull ideas together, create prototypes, and mix and match ideas to come up with the best possible choices. Does this career exist? How would I find it? If getting a masters(which I am very willing) is necessary, then what path should I take? Thank you everyone for your help

that contains three blue and two red caps. The men are positioned in indian file in front and facing a wall. The man closest to the wall we shall call A. The second man standing behind A and also facing the wall we will call B, The third man standing behind B and also facing the wall we will call C. Caps are taken out of the box at random and placed on the heads of the three men. Of course, C can not see the color of his cap but can see the caps on A and B. B cannot see his cap nor C's cap but can see A's cap. Finally, A cannot see neither his nor A's and B's cap. C is asked if he knows the color of his hat and, after thinking for a few moments, answers that he doesn't know. Then the same question is asked of B who, after thinking for a few moments also answers that he doesn't know. Finally, A is asked the same question and, after thinking for a few moments, answers correctly. Now, the question is: What is A's cap color and how did he know?

Stephen Hawking seems to state than nucleur war is inevitable. I agree. If mankind slips back to the stone age, then he must start all over again. However, the nearest coal is a mile down and the nearest oil is five miles down. What fueled the last industrial age cannot fuel another one. Also all the great mineral deposits have been mined and scattered over the earth. A new industrial age will not be able to start again for another 500 million years when new coal and oil deposits have been created. Mankind will not survive that long as a cave man. Thus Stephen Hawking suggests we must inhabit other worlds that will not be destoried in the nucleur war on earth. How can mankind ever reach another industrial age on earth without oil and coal? Possibly this also answers Hawking's question. Maybe mankind will be stuck in a pre-industrial age of the 1700's and never again invent a way to destory itself.
