Not a scientist so here's layman explanation...

1. The hand parallel pierces the wind (less frontal area?) than the hand perpendicular (more frontal area - more drag)

2. More frontal area on the left would mean more downforce on that side to help "pin" the left side while the car turning to the left tries to throw the weight to the outside.

3. The pressure you are measuring is is failing to factor the air pressure already present outside of the tire in the atmosphere. But as most of us need to keep things pretty simple when adjusting tires, we just go off the guage instead of factoring the atmospheric pressure. Probably does make a difference though if you are racing at high altitudes.

4. Anti-freeze raises the boiling point of water and the pressurized system also changes the boil point.

5. Duhh.... What's a unisphere?
