“The prevailing wisdom that China is the next global power is breeding paranoia about China and fostering megalomania within China. Fears of an aggressive and antagonistic China that before long is destined to be the next global power are, at best, premature; and, at worst, they can become a self-fulfilling prophecy.”

“At speeds up to about 300 mph air can be regarded as incompressible, like water. In other words, the pressure differences caused by the air velocities are small compared with the pressure of the atmosphere, and so the air behaves as if its density remained constant.
For example, at 200 mph the maximum pressure that air can exert is only 5 percent of the atmospheric pressure, which has a negligible effect on the air density and the flow. But at 400 mph the pressure increases to 21 per cent and at 600 mph to 51 per cent. These pressure increases have a significant effect upon the density of the air, and, hence, upon its flow pattern and the forces that the air exerts.”
