kinetic energy

Kinetic energy is a form of energy, known as energy of motion. The kinetic energy of an object is that which is produced because of its movements that depends on the mass and speed of the same. The kinetic energy is usually abbreviated with e lettethrs "Ec" or "Ek".
sound energy
Sound (or acoustic) energy is the energy transmitted or transported by sound waves.

Marie Curie 

Physicist, Scientist, Scientist(1867–1934)


Scientist Marie Curie was the first woman to win a Nobel Prize and the only person to win the award in two different fields — physics and chemistry..
Born Maria Sklodowska on November 7, 1867, in Warsaw, Poland, Marie Curie became the first woman to win a Nobel Prize and the only woman to win the award in two different fields (physics and chemistry). Curie's efforts, with her husband Pierre Curie, led to the discovery of polonium and radium and, after Pierre's death, the further development of X-rays. She died on July 4, 1934.
Early Life
Maria Sklodowska, better known as Marie Curie, was born in Warsaw in modern-day Poland on November 7, 1867. Her parents were both teachers, and she was the youngest of five children, following siblings Zosia, Józef, Bronya and Hela. As a child Curie took after her father, Wladyslaw, a math and physics instructor. She had a bright and curious mind and excelled at school. But tragedy struck early, and when she was only 10, Curie lost her mother, Bronislawa, to tuberculosis.
A top student in her secondary school, Curie could not attend the men-only University of Warsaw. She instead continued her education in Warsaw's "floating university," a set of underground, informal classes held in secret. Both Curie and her sister Bronya dreamed of going abroad to earn an official degree, but they lacked the financial resources to pay for more schooling. Undeterred, Curie worked out a deal with her sister. She would work to support Bronya while she was in school and Bronya would return the favor after she completed her studies.
For roughly five years, Curie worked as a tutor and a governess. She used her spare time to study, reading about physics, chemistry and math. In 1891, Curie finally made her way to Paris where she enrolled at the Sorbonne in Paris. She threw herself into her studies, but this dedication had a personal cost. With little money, Curie survived on buttered bread and tea, and her health sometimes suffered because of her poor diet.
Curie completed her master's degree in physics in 1893 and earned another degree in mathematics the following year. Around this time, she received a commission to do a study on different types of steel and their magnetic properties. Curie needed a lab to work in, and a colleague introduced her to French physicist Pierre Curie. A romance developed between the brilliant pair, and they became a scientific dynamic duo. The pair married on July 26, 1895.
Discoveries
Marie and Pierre Curie were dedicated scientists and completely devoted to one another. At first, they worked on separate projects. She was fascinated with the work of Henri Becquerel, a French physicist who discovered that uranium casts off rays, weaker rays than the X-rays found by Wilhelm Conrad Roentgen.
Curie took Becquerel's work a few steps further, conducting her own experiments on uranium rays. She discovered that the rays remained constant, no matter the condition or form of the uranium. The rays, she theorized, came from the element's atomic structure. This revolutionary idea created the field of atomic physics and Curie herself coined the word radioactivity to describe the phenomena. Marie and Pierre had a daughter, Irene, in 1897, but their work didn't slow down.
Pierre put aside his own work to help Marie with her exploration of radioactivity. Working with the mineral pitchblende, the pair discovered a new radioactive element in 1898. They named the element polonium, after Marie's native country of Poland. They also detected the presence of another radioactive material in the pitchblende, and called that radium. In 1902, the Curies announced that they had produced a decigram of pure radium, demonstrating its existence as a unique chemical element.
Science Celebrity
Marie Curie made history in 1903 when she became the first woman to receive the Nobel Prize in physics. She won the prestigious honor along with her husband and Henri Becquerel, for their work on radioactivity. With their Nobel Prize win, the Curies developed an international reputation for their scientific efforts, and they used their prize money to continue their research. They welcomed a second child, daughter Eve, the following year.
In 1906, Marie suffered a tremendous loss. Her husband Pierre was killed in Paris after he accidentally stepped in front of a horse-drawn wagon. Despite her tremendous grief, she took over his teaching post at the Sorbonne, becoming the institution's first female professor.
Curie received another great honor in 1911, winning her second Nobel Prize, this time in chemistry. She was selected for her discovery of radium and polonium, and became the first scientist to win two Nobel Prizes. While she received the prize alone, she shared the honor jointly with her late husband in her acceptance lecture.
Around this time, Curie joined with other famous scientists, including Albert Einstein and Max Planck, to attend the first Solvay Congress in Physics. They gathered to discuss the many groundbreaking discoveries in their field. Curie experienced the downside of fame in 1911, when her relationship with her husband's former student, Paul Langevin, became public. Curie was derided in the press for breaking up Langevin's marriage. The press' negativity towards Curie stemmed at least in part from rising xenophobia in France.
When World War I broke out in 1914, Curie devoted her time and resources to helping the cause. She championed the use of portable X-ray machines in the field, and these medical vehicles earned the nickname "Little Curies." After the war, Curie used her celebrity to advance her research. She traveled to the United States twice— in 1921 and in 1929— to raise funds to buy radium and to establish a radium research institute in Warsaw.
 Final Days and Legacy
All of her years of working with radioactive materials took a toll on Curie's health. She was known to carry test tubes of radium around in the pocket of her lab coat. In 1934, Curie went to the Sancellemoz Sanatorium in Passy, France, to try to rest and regain her strength. She died there on July 4, 1934, of aplastic anemia, which can be caused by prolonged exposure to radiation.
Marie Curie made many breakthroughs in her lifetime. She is the most famous female scientist of all time, and has received numerous posthumous honors. In 1995, her and her husband's remains were interred in the Panthéon in Paris, the final resting place of France's greatest minds. Curie became the first and only woman to be laid to rest there.
Curie also passed down her love of science to the next generation. Her daughter Irène Joliot-Curie followed in her mother's footsteps, winning the Nobel Prize in Chemistry in 1935. Joliot-Curie shared the honor with her husband Frédéric Joliot for their work on their synthesis of new radioactive elements.
