A camera is a device that records images by using optical principles. The invention of the camera was originally used for the production of movies and TV programs, but now it has become popular. Just like cameras, early cameras needed to use negatives (that is, video tapes) for recording, but now the invention of digital cameras enables images to be stored directly in flash memory.

Newer cameras directly store image data in the hard disk of the fuselage, which can not only record dynamically, but also shoot statically, without bringing a digital camera at the same time. Family portable camera is light and easy to operate, and it is almost a necessary household appliance.

1872 One day, in a hotel in California, Leland Stanford and Cohen had a heated argument: Do horses all land when running? Stanford thinks that a running horse's hoof is empty at the moment of jumping; On the other hand, Cohen thinks that horses always touch the ground when running.

No one could convince anyone of the result of the argument, so the usual bet method was adopted to solve it. They hired an excellent horse trainer to judge, however, it is difficult for the referee to judge who is right and who is wrong. This is normal, because it is really difficult to see how the fast-running horseshoe moves with the human eye alone.
