Science & Mathematics - 7 November 2006

1. week of 10-29-06, science channel showed evidence that coal is burned in large plant to create high-pressure CO2 that is then pumped into canadian & us oil wells thought to be dry. but oil exists in rocks, & the CO2 pushes it out. how can it be that the CO2, a gas, stays down in the earth and never comes out as CO2? ... 2. in addition, what other means are now used to get extra oil out of the earth where it has already been drilled?
3. what is there to that "peak oil" theory that says that petroleum is forever being produced by processes at the center of the earth, which will create an infinite source of petroleum??? i think all oil comes from pressures of waters and sediments upon carbon-based life forms, not from volcanic activity or magnetism at center of the earth.

Just because air is not present to be moved, Im not at all convinced that the sound just doesnt exist and its properties could not be measured.

Infact without air to "vibrate" would the properties of sound be effected or just remain in audible to the human ear?

Okay - it makes sense that over the years that early humans may have trekked many thousands of miles to populate other land masses. My question is how did they get on those little islands in the middle of the Pacific Ocean thousands of miles from any land mass?

If you have five marbles lined up and roll a marble into them - one marble shoots off the end

If you roll two marbles into the the row of 5 then two marbles shoot off the end

Both of these scenarios make perfect sense.... now here's the twist.....

Set up one marble just in front of the 5 - roll two marbles into the single marble so that it strikes the five.....

How many marbles shoot off the end? And why?
