Antonie Lavosier
was a French nobleman prominent in the histories of chemistry and biology.[2] He found and termed both oxygen (1778) and hydrogen (1783), helped construct the metric system, put together the first extensive list of elements, and helped to reform chemical nomenclature. He was also the first to establish that sulfur was an element (1777) rather than a compound.[3] He discovered that, although matter may change its form or shape, its mass always remains the same. -

Amadeo Avagadro
was an Italian savant. He is most noted for his contributions to molecular theory, including what is known as Avogadro's law. In tribute to him, the number of elementary entities (atoms, molecules, ions or other particles) in 1 mole of a substance, 6.02214179(30)×1023, is known as the Avogadro constant. -
william crooks
was a chemist and physicist who attended the Royal College of Chemistry, London, and worked on spectroscopy. He was a pioneer of vacuum tubes, inventing the Crookes tube. -
J.J. Thompson
was a British physicist and Nobel laureate. He is credited for the discovery of the electron and of isotopes, and the invention of the mass spectrometer. Thomson was awarded the 1906 Nobel Prize in Physics for the discovery of the electron and for his work on the conduction of electricity in gases. -
Madame Curie
as a Polish–French physicist–chemist famous for her pioneering research on radioactivity. She was the first person honored with two Nobel Prizes, in physics and chemistry. She was the first female professor at the University of Paris. She was the first woman to be entombed on her own merits (in 1995) in the Paris Panthéon. -
Robert Millikan
was an American experimental physicist, and Nobel laureate in physics for his measurement of the charge on the electron and for his work on the photoelectric effect. He served as president of Caltech from 1921 to 1945. He also served on the board of trustees for Science Service, now known as Society for Science & the Public, from 1921-1953.

Albert Einstein
was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history. -
Erwin Schrodinger
as an Austrian physicist and theoretical biologist who was one of the fathers of quantum mechanics, and is famed for a number of important contributions to physics, especially the Schrödinger equation, for which he received the Nobel Prize in Physics in 1933. In 1935, after extensive correspondence with personal friend Albert Einstein, he proposed the Schrödinger's cat thought experiment.[1] -
louise debrogile
was a French physicist and a Nobel laureate in the year 1929. He was the sixteenth member elected to occupy seat 1 of the Académie française in 1944, and served as Perpetual Secretary of the Académie des sciences, France. -
Henri Becquerel
was a French physicist, Nobel laureate, and the discoverer of radioactivity along with Marie Curie and Pierre Curie, for which all three won the 1903 Nobel Prize in Physics. -
First Men to South Magnetic Pole
In 1907 the famous Anglo-Irish explorer Henry Shackleton recruited Douglas Mawson, an Australian geologist and 50 year old lieutenant Edgeworth David for a South Pole Expedition. The plan was for Shackleton and three men to travel to the geographic South Pole while David and two companions traveled to the magnetic pole. In October 1908 David’s men followed the coast north. Ten weeks and over 1,200 miles later the men arrived at the South Magnetic Pole. -
William Howard Taft Inauguration
Ih169113 Taft was the 27th President of the United States and won the 1908 election by a wave of popular support thanks to previous president and fellow republican, Theodore Roosevelt. A severe and unusual March blizzard hindered the Taft inauguration ceremonies. It took 6,000 city workers and 500 wagons half the night to remove 58,000 tons of snow and slush to clear the parade route. -
Titanic Construction Begins
The R.M.S. Titanic was built at the Harland and Wolff shipyard in Belfast Ireland. It was designed to be the largest ship to ever take to the seas and took 3000 men 3 years to build at a cost of 7.5 million dollars. Titanic’s hull was launched on May 31, 1911 without her engines, boilers, machinery, and furnishings. She was then towed to deeper waters and was completed on March 31, 1912. -
First Men to Reach North Pole
In February 1909, American Navy engineer Robert Peary, several Inuit tribesmen, and fellow American of African descent, Matthew Henson, left their ship anchored at Ellesmere Island’s Cape Sheridan. After traveling 480 miles the men reached the geographic North Pole. Peary wrote in his journal: “The Pole at last!!! The prize of 3 centuries, my dream and ambition for 23 years. Mine at last -
Tel Aviv Founded
Tel Aviv was founded on the second day of Passover, 1909. Sixty-six Jewish families gathered on a desolate sand dune outside Yafo which is now Rothschild Boulevard. The plan was to build a Hebrew urban centre in a healthy environment according to the rules of aesthetics and modern hygiene. They parceled out the land by a kind of lottery system. They gathered 60 grey shells and 60 white shells. -
Heavier than Air Flight
This historic first heavier than air flight across the English Channel by French aviator Louis Bleriot was funded by a grateful family after Bleriot’s wife saved their child from falling to his death. They loaned the almost bankrupt Blériot 25,000 francs which helped him perfect his Blériot XI airplane. The day he took off from Les Barraques, France to cross the channel, Blériot was on crutches because of a recent accident. -
Indianapolis Motor Speedway Opens
The first motor race at Indy was actually with motorcycles rather than automobiles. It consisted of 7 motorcycle races, sanctioned by the Federation of American Motorcyclists. The first of the automobile races took place August 19-21, 1909, and consisted of 16 races sanctioned by the American Automobile Association. The photo above shows the start of the1909 Wheeler-Schebler Trophy 300-mile Race which featured 19 of the world’s most powerful cars. -
First Paris Air Show
Screen Shot 2009-12-22 At 1.36.59 Pm The first air show in Paris was held at the Grand Palais. Visitors came to admire the early flying machines and also buy them. “A Wright aircraft cost 30,000 francs, a Farman biplane cost 23,000 and a Blériot like the one that just flew across the English Channel cost just 10,000. A magazine writer described the first Paris Air Show this way: -
Tallest Building in the World

The Cherry Mine Disaster
The Cherry, Illinois mine disaster is one of the worst accidents in American industrial history. The tragedy occurred after the electrical system went down and workers had to use makeshift torches. As they were lowering a car full of hay to feed the mules stabled underground, a torch ignited the hay and filled the mine with smoke. -
henry mosely
was an English physicist. Moseley's outstanding contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's Law justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a quite logical order based on their physics. -
ernest rutherford
was a New Zealand-born British chemist and physicist who became known as the father of nuclear physics.[2] In early work he discovered the concept of radioactive half-life, proved that radioactivity involved the transmutation of one chemical element to another, and also differentiated and named alpha and beta radiation. This work was done at McGill University in Canada. It is the basis for the Nobel Prize in Chemistry he was awarded in 1908 " -

was a German theoretical physicist who made foundational contributions to quantum mechanics and is best known for asserting the uncertainty principle of quantum theory. In addition, he made important contributions to nuclear physics, quantum field theory, and particle physics. -
James chadwick
was an English Nobel laureate in physics awarded for his discovery of the neutron. -
Democritus
Democritus of Abdera - he developed atomic theory; elaborated idea that matter consisted of atoms having physical size and shape which constantly moved in a void and interacted in different ways; Greek word atoma means indivisible. -
aristotle
was a Greek philosopher and polymath, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology.
