Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish biologist, pharmacologist and botanist. He wrote many articles on bacteriology, immunology, and chemotherapy. His best-known discoveries are the enzyme lysozyme in 1923 and the antibiotic substance penicillin from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.

In 1999, Time magazine named Fleming one of the 100 Most Important People of the 20th Century, stating:

    It was a discovery that would change the course of history. The active ingredient in that mould, which Fleming named penicillin, turned out to be an infection-fighting agent of enormous potency. When it was finally recognized for what it was, the most efficacious life-saving drug in the world, penicillin would alter forever the treatment of bacterial infections. By the middle of the century, Fleming's discovery had spawned a huge pharmaceutical industry, churning out synthetic penicillins that would conquer some of mankind's most ancient scourges, including syphilis, gangrene and tuberculosis.

Albert Einstein

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"),he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".The latter was pivotal in establishing quantum theory.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.

He was visiting the United States when Adolf Hitler came to power in 1933 and did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming an American citizen in 1940.On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential developing of "extremely powerful bombs of a new type" and recommending that the U.S. begin similar research. This eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery of nuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

Einstein published more than 300 scientific papers along with over 150 non-scientific works.His great intellectual achievements and originality have made the word "Einstein" synonymous with genius.

James Watt

James Watt(19 January 1736 – 25 August 1819)was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.

While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and re-heating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.

Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775. The new firm of Boulton and Watt was eventually highly successful and Watt became a wealthy man. In his retirement, Watt continued to develop new inventions though none were as significant as his steam engine work. He died in 1819 at the age of 83. Watt has been described as one of the most influential figures in human history.

He developed the concept of horsepower and the SI unit of power, the watt, was named after him.

Thomas Alva Edison

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park",he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.

Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.

His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison developed a system of electric-power generation and distribution
to homes, businesses, and factories – a crucial development in the modern industrialized world. His first power station was on Pearl Street in Manhattan, New York.

The Wright brothers

The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who were credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903. From 1905 to 1907, the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.

The brothers' fundamental breakthrough was their invention of three-axis control, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium.This method became standard and remains standard on fixed-wing aircraft of all kinds.From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines.Using a small homebuilt wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design and build wings and propellers that were more efficient than any before.Their

They gained the mechanical skills essential for their success by working for years in their shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles in particular influenced their belief that an unstable vehicle like a flying machine could be controlled and balanced with practice.From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their bicycle shop employee Charlie Taylor became an important part of the team, building their first aircraft engine in close collaboration with the brothers.
first U.S. patent, 821,393, did not claim invention of a flying machine, but rather, the invention of a system of aerodynamic control that manipulated a flying machine's surfaces.

Bangla town in London!

Winding through fields, the street was formerly called Whitechapel Lane. It derives its current name from brick and tile manufacture started in the 15th century, which used the local brick earth deposits.By the 17th century, the street was being developed from the south as a result of expanding population.

Brewing came to Brick Lane before 1680, with water drawn from deep wells. One brewer was Joseph Truman, first recorded in 1683. His family, particularly Benjamin Truman, went on to establish the sizeable Black Eagle Brewery on Brick Lane.The Brick Lane Market first developed in the 17th century for fruit and vegetables sold outside the City.

Successive waves of immigrants settled in the area: in the 17th century, French Huguenots expanded into the area for housing; the master weavers were based in Spitalfields.Starting with the Huguenots, the area became a centre for weaving, tailoring and the developing clothing industry. It continued to attract immigrants, who provided semi- and unskilled labour.

In the 19th century, Irish,and Ashkenazi Jews immigrated to the area.jewish immigration continued into the early 20th century.

The Sunday market, like the ones on Petticoat Lane and nearby Columbia Road, dates from a dispensation given by the government to the Jewish community in the 19th century. At the time, there were no Sunday markets open because of the Christian observance of Sabbath. Located at the junction with of Cheshire and Sclater streets, the market sells bric-a-brac as well as fruit, vegetables and many other items. Near the junction with Hanbury Street are two indoor markets; Upmarket and Backyard Market. In 2010, the Brick Lane Farmers' Market opened, intended to be held every Sunday in nearby Bacon Street;it has now closed.
In the later 20th century, Bangladeshis comprised the major group of immigrants and gradually predominated in the area.Many Bangladeshi immigrants to Brick Lane were from the Greater Sylhet region. These settlers helped shape Bangladeshi migration to Britain; many families from Jagannathpur and Bishwanath tend to live in the Brick Lane area.

Rishi Bankim Chandra Chattopadhyay

Rishi Bankim Chandra Chattopadhyay(27 June 1838 – 8 April 1894)was a Bengali writer, poet and journalist.He was the composer of India’s national song Vande Mataram, originally a Bengali and Sanskrit stotra personifying India as a mother goddess and inspiring the activists during the Indian Freedom Movement. Bankim Chandra wrote 13 novels and several ‘serious, serio-comic, satirical, scientific and critical treaties’ in Bengali. His works were widely translated into other regional languages of India as well as in English.

Bankim Chandra was born to an orthodox Brahmin family at Kanthalpara, North 24 Parganas. He was educated at Hoogly College and Presidency College, Calcutta. He was one of the first graduates of the University of Calcutta. From 1858, until his retirement in 1891, he served as a deputy magistrate and deputy collector in the Government of British India.

Bankim Chandra is widely regarded as a key figure in literary renaissance of Bengal as well as India. Some of his writings, including novels, essays and commentaries, were a breakaway from traditional verse-oriented Indian writings, and provided an inspiration for authors across India.

When Bipin Chandra Pal decided to start a patriotic journal in August 1906, he named it Vande Mataram, after Bankim Chandra's song. Lala Lajpat Rai also published a journal of the same name.
