Lomocotive
They were powered by steam. The first steam locomotive was built by Richard Trevithick in 1804 but This machine did not work because it was running on cast iron rails inappropriate for its weight. -
Frensel's lens
The Fresnel's lens, named for its inventor, French physicist Augustin-Jean Fresnel, is a design that allows the construction of large aperture lenses and a short focal length without the weight and bulk of material that should be used in a lens of conventional design.
When the lenses are large, their thickness can become excessive, making the lens very heavy and expensive. Instead, the radio of curvature of the lenses can be maintained by separating them into circular rings. -
Fotography
The first photographic procedure was invented by Niépce around 1824. The images were obtained with bitumen from Judea, spread on a silver plate, after an exposure time of several days. With the passage of time, they developed, from the residue of the distillation of lavender essence, a second procedure that produces images with an exposure time of a whole day. -
Electric vehicle
The electric car was the first of the cars to be developed. Between 1832 and 1839 (the exact year is uncertain), the Scottish businessman Robert Anderson, invented the first pure electric vehicle. Professor Sibrandus Stratingh from Groningen in the Netherlands designed and built with the help of his assistant Christopher Becker small-scale electric vehicles in 1835.
The improvement of the electric battery, paved the way for electric vehicles. -
Anesthesia
It is usually considered as the first anesthesia understood as a method to achieve insensitivity of the patient in a surgical intervention, the one performed on October 16, 1846 by William Thomas Green Morton in Boston (Massachusetts). But behind this milestone is the work and commitment of many previous characters such as dentists, surgeons or chemists who with their contributions and discoveries allowed its development. -
Telephone
The invention of the telephone is due to the Italian Antonio Meucci, an expert in the area of
electrodynamics. This Florentine inventor created in 1854 a device that he baptized as
"teletrófono" with the intention of being able to connect your office with the bedroom of the plant
top of your house.
It was actually a device that could
transmit acoustic signals at a distance by means of electrical signals. -
Clinical thermometre
Clifford Allbutt published "Medical Thermometry," an article that summarizes the history of thermometry and the description of its invention: a clinical thermometer about 6 inches (15 cm) long that a physician could routinely carry in a pocket. His version of the thermometer, devised in 1867, was quickly adopted elsewhere, in place of the model previously in use, which was one foot long (30 cm) and which patients were required to hold for about twenty minutes. -
Incandescent lamp
American inventor Thomas Alva Edison succeeded with his test of leaving an incandescent filament burning for several days. Since then, that day is considered the date of birth of the bulb. Three months later, on January 27, 1880, Edison, 32, filed a patent for his invention and began mass production. -
Coca-Cola
The faurmacetic John S. Pemberton who wanted to create a syrup against digestion problems that also provided energy.
It didn't take long for Pemberton to realize that the drink he had created could be a success. His accountant, Frank Robinson, was the one who came up with the brand and designed the logo: Coca-Cola was born. Barely 11 years had passed since its creation in a pharmacy when, in 1897, Coca-Cola first left the United States. -
Aspirin
Félix Hoffmann reported the procedure followed to obtain the so-called acetylsalicylic acid.
The popular "Aspirin", useful for relieving headaches, muscle pain, and many other uses that over time have been added to the properties of this "white pill".
