Over a decade earlier, inPierre Curie and his brother Jacques had discovered piezoelectricity. The 80m tonnes of the stuff that is made each year is the result of two accidental discoveries. Louis Pasteur — Famous For: She had her Discoveries in chemistry and physics two children inoculated with smallpox and they survived without any lifetime effects.

12 scientists and their brilliant inventions

Advertisements Author of this page: It was already known that liquid crystal displays LCDs were possible, the problem was that they only really worked at high temperatures. His work in molecular biology and quantum chemistry A recipient of the Nobel Prize in the field of chemistry in Discovered by French scientist Louis Pasteur in the s, pasteurization was a method by which milk was heated to a high temperature and then cooled down quickly before it was bottled.

The idea that other parts of the world used for preventing smallpox was inoculation. He also accurately described how it plays a role in combustion. Prior to the acceptance of the scientific method and its application to the field of chemistry, it is somewhat controversial to consider many of the people listed below as "chemists" in the modern sense of the word.

Discovered the ozone hole in the Antarctic As one of three recipients of the Nobel Prize in Chemistry inMolina co-discovered the harm that chlorofluorocarbons had on the ozone layer.

Joseph Priestley is the scientist who is credited with discovering oxygen inbut Antoine Lavoisier gets the credit for discovering the element that oxygen is made from. The first is that atoms composed chemical elements. Penicillin The discovery of penicillin is credited to Alexander Fleming, a Scottish scientist and Nobel Prize winner in When he picked up one of the dishes to show Pryce, he noticed that there was a mold in the dish that had killed the staphylococcus bacteria that was growing in there.

In fact, it was almost thrown away in the trash.

Important Dates and Discoveries

However, there is some controversy over who was actually the first person to discover this all-important element. Many scientists worked with cathode tubes which created streams of electricity, but they were not sure how it actually worked.

An inventor is someone who tries to create useful products and devices.

10 Greatest Discoveries in Chemistry

This helped the milk stay fresh for a long period of time. Many people brought their children to be inoculated and even the Royal Family had their children inoculated, only after the condition that six prisoners would be inoculated first.

John Dalton — Famous For: Unfortunately, he learned later that Thomas Edison had got there first! It is also claimed that he is the first to use the word "chemistry". However, he found out that electric currents were composed of moving electrons.

Famous Chemists

And since he was such an influential person of his time and even beyond his time, the philosophy of an atomic theory was largely dismissed for several centuries.

Benjamin Franklin Lived — Benjamin Franklin discovered one of the fundamental laws of physics — the Law of Conservation of Electric Charge — and proved that lightning is electricity.

The periodic table consists of all of the chemical elements that are known and they are arranged and organized on the table according to their electron configurations, atomic numbers, and their recurring chemical properties.

Polythene — the accidental invention They may be plastic but they are vintage and very valuable. He began going through his stack of Petri dishes, some that were not submerged in the Lysol.

He described seen amazing pictures and intense colors in a kaleidoscope fashion. Most of those who survived smallpox had scars and problems for the rest of their lives after the infection.

The book contains the results of numerous experiments and establishes an early version of the law of conservation of mass. He also invented the Microwave Phased Array Antenna, a type of radar which dramatically enhanced air safety in poor weather conditions by giving ground crew very precise information about aircraft positions, allowing them to land safely.

Pasteurization The process of pasteurization has been called one of the most important discoveries in science and chemistry because of the numerous lives that it has saved through preventing disease. The screen you are reading on LCD screens rock. She was a member of the British nobility and she lived in Turkey during the time her husband, a British ambassador, was stationed there.

Until in it took Australian pharmacologist Howard Florey and his team of chemists to figure out a way of purifying penicillin in useable quantities. This is where very small particles of the disease was given to a person, either inhaled through their nose or through an opening on their skin.Greatest Discoveries - Physics.
