First planes, what's next?

Were as the idea for planes and the physics behind them make sense, the helicopter is completely different. In order to create the same lift as a plane does by getting air pass over the wings very fast, a helicopter has to lift by spinning it's rotor blades very fast. the same principle of fluid dynamics is responsible for the lift force on a helicopter. The blades on a helicopter are shaped almost the exact same as plane wing so that when they are spun they create a upward force on the helicopter. All the blades together spinning create a small low pressure system above the blades and the air below pushes up. However since the helicopter is in the air, they is no force to stop the cabin of the helicopter from being spun the other way which is why almost all helicopters have the tail rotor which uses the same physics to create a force that keeps the fuselage from spinning. Using physics we have been able to conquer the sky.
