the camera

A camera is a device used to take pictures. It is an ancient mechanism for projecting images where an entire room was the same functions as a camera present on the inside, with the difference that in those days there was no possibility of saving the image unless it be drawn by hand. The existing cameras can be sensitive to visible spectrum or other portions of the electromagnetic spectrum and its main use is to capture the visual field.

Clock

I'm going to write about clock.

The first watch created by man was a solar one, which indicated the moments of the day by folowingthe shalows of the sun. The chineese used this method about 3000 years before christ. It was also used by the egyptians and incas. These watches had de desadvantage of not being accuarate at dawn, overcasted days and night. The romans marked candles as a rule to control the time at night. In Babylon, Egypt, Grece and Rome they guided themselves by water. The first motor of a clock was created with weights by Pacific in the eight century. In the decade of 1300 was posible to see these watches in cathedrals in Europe. The oldest one is kept in the cathedral of Salisbury.

In 1641 Galileo conceived the principle of the pendlum and Huygens developt the project by the construction of the first mecanical pendlum clock, amazing with rhythmical pendular movements and sweet bell ceremonies.

The Incandescent Lamp

Thomas Alva Edison invented the first Incandescent Lamp on 21th of October, 1879. The bulb remained shining 48 hours uninterrupted. It´s one of the most used inventions in the history. A lot of scientists said that they invented the first Incandescent Lamp, but Thomas was the first who patent it.

The Incandescent Lamp is the one with the shortest life and the and it´s true that is not the one with the best efficient, only the 15% of the energy it´s used for light, but is famous becous it´s the cheapest.

One of the most famous disputes over the patenting of the incandescent lamp was between Thomas Edison and Heinrich Göbel, who said that he invented the fist one at 1854, but many

lawsuits estimated that it was very unlikely that Heinrich Göbel had invented the light bulb on that date, so the invention was attributed to Thomas Edison.
