Paul Dirac

British mathematical physicist, co-winner with Erwin Schrodinger of the 1933 Nobel Prize in Physics “for the discovery of new productive forms of atomic theory.” He was born in Bristol, England, on August 8, 1902. Physicists rank Dirac among the top theorists of the 20^th century. Most of his research was concerned with quantum mechanics, the best theory so far for describing the behavior of molecules, atoms, and things that are even smaller. He published nearly 200 scientific papers and seven books, the most important of which, Principles of Quantum Mechanics, went through four editions. The influence of the book on several generations of physicists has been profound.

Antoine Laurent Lavoisier

http://portrait.kaar.at

French chemist, was born Paris, August 26, 1743. Lavoisier studied law together with mathematics, astronomy, botany, and chemistry at the College Mazarin. His interest in chemistry, aroused undoubtedly by his great teacher, G.F. Rouelle, at the age of 21, although fully trained for the legal profession and admitted to the Frenh bar. Lavoisier dedicated his life to science and by 1765 his first scientific paper was presented to the Academie des Sciences. In 1770 Lavoisier began his studies on combustion, and two years later he deposited sealed sulphur and phosphorous increased in weight when burned in air, while lead oxide decreased in weight upon its reduction to lead. These studies made it possible for him to propose the oxygen theory immediately following Joseph Priestley’s announcement in 1774 of the discovery of oxygen. Lavoisier published a reformed system of chemical terminology in 1787 and a complete reclassification of the elements in 1789. He died on May 8, 1794.

Sir Oliver Joseph Lodge

http://www.martinlogan.com

English physicist was born in Penkhull, Stafforshire on June 12, 1851. Educated in University College, London, he taught there from 1875 to 1881. He was a professor of physics at University College, Liverpool, from 1881 to 1900: then first principal of University of Birmingham, from 1900 to 1919. His scientific researches covered a wide field, including investigations into the phenomena of lightning, electric charges and forces, and wave propagation in wireless telegraphy. After his eminent success as a research physicist and pioneer in wireless telegraphy and as an educational reformer, in 1910 he became interested in psychic phenomena and spiritualism, and in the reconciliation of science and religion. He was knighted in 1902, and died August 22, 1940.

Sir Francis Galton

http://galton.org

An English scientist and anthropologist, Galton is known primarily for his work eugenics, the study of hereditary qualities to improve human race. Francis Galton was born on February 16, 1822, in a village near Birmingham, England. Galton studied medicine, but on the death of his father he found himself with sufficient fortune to make him independent of the medical profession and able to devote himself to scientific research and indulge his passion for travel. His varied journeys, during which he obtained firsthand knowledge of primitive people, culminated in a successful exploratory expedition in southwest Africa (1850-1852) for which, in 1853, the Royal Geographical Society awarded him its Gold Medal. In Inquiries into Human Faculty (1883) Galton first used the word “eugenics” to describe his theory of improving the human race by controlling hereditary factors. The Eugenics Society was founded in London in 1908, with Galton as its first honorary president. He was honored by scientific societies all over the world, and was knighted in 1909. He died at Hazlemere, Surrey, on January 17, 1911.

Edward Jenner

An English physician, he was the first to establish a vaccination on a scientific basis with his studies on smallpox. He was born on May 17, 1749 in Berekely, a small town in Gloucestershire, England. In 1788, he married Katharine Kingscote and bought The Chantry, a pleasant house in Berekely. Because of his wife’s delicate health, he spent the summer months at Cheltenham Spa, where, after receiving his M.D. from St. Andrew’s University in 1792, he succeeded in building up considerable medical practice. For many years he had made study of cowpox, and on May 14, 1796, he inoculated a boy named James Phipps with material taken from a cowpox pustule on the hand of the dairymaid Sarah Nelmes. The boy developed typical cowpox. Six weeks later, he was inoculated with smallpox, and it failed to have any effect. Other experiments followed, and enner published the results. He died on January 26, 1823.

Viktor Meyer

A German chemist, noted for his discoveries of organic compounds, was born in Berlin on September 8, 1848. Young Viktor was taken to Heidelberg in the hope of arousing his intellectual interest, and this was accomplished at a lecture by the famous R.W. Bunsen, to whom Meyer later became an assistant. He studied in Berlin and later at Heidelberg under Bunsen, receiving his doctor’s degree there in 1867. In 1889 he succeeded Bunsen at Heidelberg as head of the most famous chemical laboratory in the world. Meyer was a pioneer in the field of organic chemistry. His major work includes the discovery of thiophene and its derivatives (in 1883), his studies in the constitution of camphor, chloral hydrate, aliphatic nitro-compounds (1872), nitriolic acid, the synthesis of diphenylmethane from benzyl alcohol and benzene (1882). In 1871, he invented a method of determining vapor densities. He died in Heidelberg on August 8, 1897.

Science Trivias - Body Edition

This Science Trivia post is all about the body... 


TRIVIA 1: When we sneeze, air rushes through our nose at a rate of 100 mph (160.93 km/h). Can you say, achooo?

TRIVIA 2:An eyelash lives about 150 days before it falls out. It is barely noticeable, but it also doesn't mean we could just ignore taking care of it. Careful on the eyelash curlers, girls!

TRIVIA 3:Each of our eyes has 120 million rods, which helps us see in black and white. That's a LOT, and quite amazingly interesting.

TRIVIA 4:One in 12 men is color blind. But at least, it's better to admit you're color blind than just not knowing the difference between PINK and FUCHSIA.

TRIVIA 5:The strongest muscle of the body is the masseter muscle, which is located in the jaw. Yup, it's so strong it LOCKS itself. (Lockjaw)

The Science of LOVE - ATTRACTION

ATTRACTION is one of the 3 STAGES OF LOVE as according to Helen Fisher of Rutgers University. This particular stage is driven by different hormones and chemicals...

http://1.bp.blogspot.com

Scientists think that three main neurotransmitters are involved in this stage; adrenaline, dopamine and serotonin.

Adrenaline

http://3.bp.blogspot.com

Falling for someone activates your stress response, increasing your blood levels of adrenaline and cortisol. This is the very reason why despite silly things happening, the "charming" effect kicks in.

Dopamine

http://omflit.files.wordpress.com

Helen Fisher asked newly ‘love struck’ couples to have their brains examined and discovered they have high levels of the neurotransmitter dopamine. This chemical stimulates ‘desire and reward’ by triggering an intense rush of pleasure. In fact, it has the same effect on the brain as taking cocaine!

Serotonin

One of love's most important chemicals is Serotonin. This explains why when you are falling in love, he or she keeps popping in your thoughts.

The Science of L O V E

When do we actually know if we fancy someone?

What does L O V E do to our brain chemicals?

 Is L O V E nature's only way to keep our species alive?

http://mashedmusings.files.wordpress.com

Whatever we call it, however we feel it, we all know we've been through it before. 

With an irresistible cocktail of chemicals, our brain entices us to fall in love. We believe we’re choosing a partner. But we may merely be the happy victims of nature’s lovely plan.

Psychologists have shown it takes between 90 seconds and 4 minutes to decide if you fancy someone.

And by that, it means that words said are all but nonsense...

Research says that:

55% is through body language

38% is the tone and speed of their voice

Only 7% is through what they say
