Energy
Energy:
Measure of the
ability of a body or system to do work or produce a change. No activity is
possible without energy and its total amount in the universe is fixed. In other
words, it cannot be created or destroyed but can only be changed from one type
to another. The two basic types of energy are; Potential: energy associated
with the nature, position, or state (such as chemical energy, electrical
energy, nuclear energy). Kinetic: energy associated with motion (such as a
moving car or a spinning wheel).

Marie Curie
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.
