CANES 38 GATORS 33 We were down 10-33 when I left the stadium, and as soon as I was walking out of the stadium, the Hurricanes showed us why we're the best by mounting a classic comeback to defeat the Gators, complete with a interception with 6 seconds on the clock with Florida in danger of making another touchdown. GO CANES

Drug legalization actually decreases use too.

We could also go back about 125 years, to the first car. Less than 100 years later, we went from the first cars to space shuttles.

In a combustion reaction electrons move to a higher energy state, emitting photons based on what orbital they're in, which accounts for the color of a flame.

Hopefully by the time heat death is upon us, we'll be walking among the galaxies and be able to do something about it. Assuming that happens. But by the time the sun goes nova, I firmly believe we'll have moved beyond this solar system. In 1000 years, we've gone from chariots to space shuttles... imagine where we'll be in 10,000 years... much less in millions of years when it happens.

F=ma, how does it have a force acting on it but not an acceleration? :sum:F = 0, :sum:a = 0

I fail to see what your problem is with what I'm saying. | = ma (a=g, not zero) v [] = 0, the TOTAL SUM OF ALL FORCES IS ZERO, HENCE *TOTAL* a = 0 ^ | = -ma (a=g, not zero) The object has TWO NON-ZERO ACCELERATIONS FROM FORCES ACTING ON IT, THESE ARE EQUAL AND OPPOSITE SO THE *TOTAL* ACCELERATION IS ZERO.

So basically you're saying the idea of a downward force and normal force are bunk?

It all goes back to there being two equal and opposite forces. v=0i+(mgt+-mgt)j. There are two forces which cause two accelerations that make to total accleration 0.

The downward force on the object is mg, f=ma, A IS NOT ZERO. THe normal force is ma in the +y direction, =mg, so the NET acceleratation is zero, but there is an acceleration.

Yes, it's acclerating, but the table is exerting an upward force on it equal to the mass of the phone * acceleration due to gravity.

Higher intelligence up to a point is an evolutionary advantage, smarter people are less likely to get killed.

The appendix servers a role in the immune system, so it's not likely to disappear any time soon.

The current model of evolution includes the puncuated equilibrium theory. Speciation occurs rapidly, followed by long periods of little change, driven by sudden changes in the environment. The odds of something dying and forming a fossil are very small, so intermediate species do not exist long enough to have a high chance of forming one.

Physically we're not likely to change much, since there are few changes that impact survival. Obesity may be reduced if current views on desirability of obese people holds (back in the day, it didn't). Our immune systems will certainly be alot stronger. Some small changes may also occur due to genetic drift.

No particular time coordinate makes the trip noticeably shorter.

This entire discussion is flawed as you can never escape the Earth's gravity.

The shortest distance between two points is a straight line *in all 3 dimensions*. Due to the curvature of the Earth, it is not possible to travel in a straight line across large distance, and it becomes shorter to travel along a curved path to reduce the distance caused by Earth's curve.

The half-life for different isotopes of radioactive elements is variant. The half-life of 233U is 1590 years, however the amount of it in existance is vanishingly small. 238U has a half-life of 4.46 billion years, and accounts for 99.2745% of all Uranium on Earth.

In Nevada (NOT Las Vegas... Nevada law prohibits it in large cities), the way most legal brothels are set up require weekly STD tests for all girls, as well as other safety precautions. This system works out quite well, and quite safe for clients. Moral issues are between the women and the client, and should not be between the client and the state; it is not the place of the government to dictate of the morals of two consenting adults.

Or not. The prevailing evidence suggests that parts of an RNA strand itself acted (and continues to act) as an enzyme, catalyzing translation along other parts. Furthermore, biological energy molecules are structurally very similar to RNA bases (ATP, GTP, CTP, UTP), indicating that further back these may have also played a role in RNA being a truly self-replicating molecule.

When considering genetic engineering its important to note that environmental factors also contribute to development. In an experiment that involved cloning cats, the cloned cats had idential DNA, but the appearance of their fur (color, pattern, etc) was competely different than the original.
