Believe it or not that the animals around us a lot of use physics?
Call it a bird. Birds have wings that are perfectly designed, suitable to fly. The shape of the wings are aerodynamics to make the air can flow more quickly on the upper surface so cause the difference air pressure between the wing upper and lower wings. This difference pressure air is able to overcome the gravitational attraction so that the bird can fly smoothly.
If from the birds we can study the principles of flying, we can also observe how take off the duck that push leg to produce the jet energy so it is allowing to shot into the air. From dolphins we can learn the navigation system whereas bat gives us a lesson about using of radar methods.
To learn about adapting to the environment temperature, we can observe the life of some animal. The long-eared rabbit in the United States known as Jackrabbit, It has power area with temperature surface land in summer be able to reach 70 °C. In order to stay alive, although it never studied the laws of physics Wien about thermal radiation processes in school, Jackrabbit applies in the nest.
Therefore if you go to the zoo or the beach recreation, gardens, parks, or just spend time at home with a pet, don't forget to observe the shape and structure the behavior of animal. And then actually we have gotten a physics course. Free!
