Robert Boyle is considered to be the "father of chemistry," and he is only known to have invented the famous air pump that he used to study air pressure. Boyle was also responsible for several achievements in physics and chemistry, including detecting the rule of air inside the transmission of sound, determining the differences between compounds and mixtures, analyzing crystals, analyzing electricity, analyzing hydrostatics and analyzing refractive energy.
Boyle invented the famous air pump in 1659 with Robert Hooke. The discoveries that the two made were published in Boyle's very first scientific publication called "New Experiments Physico-Mechanicall, Touching the Spring of Air and Its Effects," which was published in 1660. Throughout the publication, the two explored combustion, the transmission of sound and respiration.
Boyle's Law was named after Boyle when one of their findings expressed the inverse relationship between the volume of gas and the pressure of gas. It was discovered when the two were measuring the volume present in a constant air quantity when the air was compressed by contrasting weights of mercury.
Boyle was always reluctant to form specific theories, and preferred to perform additional experiments with observation. He believed that it was important to look at the world as a natural phenomenon, and believed in a mechanical philosophy of the world.Learn More
In 1498, the Chinese created the first toothbrush as it is known today with bristles and a thin handle.Toothbrushes were mentioned as far back as 3,000 BC. They were described as chew sticks that were made of twigs with split threads at the end that could be rubbed vigorously against the teeth to remove food and plaque.Full Answer >
Although widely and erroneously credited to 19th-century British plumber Thomas Crapper, the modern flush toilet was actually invented in 1596 by Sir John Harrington. His treatise, titled "A New Discourse of a Stale Subject, Called the Metamorphosis of Ajax," described an early type of flush toilet.Full Answer >
Thomas Edison's favorite invention was the phonograph. Edison invented the phonograph in 1877. It was through his efforts to improve the telephone and telegraph that he conceived the idea to record sound on tinfoil-coated cylinders.Full Answer >
John Bird invented the sextant in 1759. His work was based on prior work by John Hadley and Thomas Godfrey, who separately invented the octant. He also relied on the work of Sir Isaac Newton regarding the principles of a doubly reflecting navigation instrument.Full Answer >
