Dr. Patricia Bath Dr. Patricia Bath. We continued our unit on Black History today and were excited to learn about Dr. Patricia Bath! Dr. Bath was the first African American to receive a patent for a medical invention. She changed the world of ophthalmology when she invented the Laserphaco Probe which is used to treat cataracts. In her honor we talked about what a trip to the eye doctor may be like.

The History of the Light Bulb In 1906, the General Electric Company was the first to patent a method of making tungsten filaments for use in incandescent light bulbs. The filaments were costly, but by 1910 William David Coolidge (1873–1975) had invented an improved method of making tungsten filaments.

HP LaserJet printer, 1984 HP LaserJet printer, 1984. The HP LaserJet was the first desktop laser printer, introduced in 1984 at about $3,500. Nothing like it existed previously, and it created a totally new printer market—similar to what the HP-35 handheld calculator had done 12 years earlier. In December 2000, HP celebrated the shipment of the 50 millionth LaserJet printer.

- Early proposals for an optical telegraph system were made to the Royal Society by Robert Hooke in 1684 and were first implemented on an experimental level by Sir Richard Lovell Edgeworth in 1767. The first successful semaphore network was invented by Claude Chappe and operated in France from 1793 through 1846.

- When the first working laser was reported in 1960, it was described as a solution looking for a problem.. But before long the laser's distinctive qualities—its ability to generate an intense, very narrow beam of light of a single wavelength—were being harnessed for science, technology and medicine.hen the first laser appeared, scientists and engineers were not really prepared for it. Many people said to me—partly as a joke but also as a challenge—that the laser was a solution looking for a problem.. But by bringing together optics and electronics, lasers opened up vast new fields of science and technology.

Robert Mayer discovers the Law of Energy Conservation Robert Mayer discovers the Law of Energy Conservation. With the discovery by Robert Mayer (1814 - 1878) of the law of energy conservation, Heilbronn made an important contribution to the history of physics. The practical application of Mayer's truth accounted for the rapid technological development in the 19th century.

Infrared Most of the thermal radiation emitted by objects near room temperature is infrared. Infrared radiation was discovered in 1800 by astronomer Sir William Herschel, who discovered a type of invisible radiation in the spectrum lower in energy than red light, by means of its effect upon a thermometer.nfrared lasers are used to provide the light for optical fiber communications systems. Infrared light with a wavelength around 1,330 nm (least dispersion) or 1,550 nm (best transmission) are the best choices for standard silica fibers.
