First Man to Walk on the Moon, Neil Armstrong, Dies

 On July 20, 1969, Neil Armstrong, Buzz Aldrin, and Michael Collins came into orbit around the Moon.  Before long, the command module Columbia separated from the Lunar Module Eagle, and Aldrin and Armstrong headed for a historic achievement.  Soon, Neil Armstrong was taking mankind’s first steps onto the moon.  This transformed the engineer into a world-wide hero, won the space race for the United States, and won Armstrong immortality as one of the nation’s true heroes.  Neil Armstrong has died at age 82.  His family put the cause of death on complications from recent cardiovascular procedures; he had been living in suburban Cincinnati, Ohio, at the time of his death.

 

The importance of the Apollo 11 mission cannot be overstated.  It is a historic achievement for all mankind, and the Apollo 11 astronauts are living treasures, memorials of one of human kind’s greatest success stories.  There’s a reason Jeff Bezos wants to get the Apollo 11 rocket boosters.  These guys were real heroes, and it’s a shame to see one of them go.

Heinrich Rudolf Hertz Google Doodle Gets Wavy!

Today’s Google Doodle honors German Physicist Heinrich Rudolf Hertz who is probably best known for the unit of measurement that bears his name.

Hertz’s experiments in electromagnetism paved the way for wireless communications, as he was the first scientist to prove the existence of electromagnetic waves. His early research served as an expansion of the theory of electromagnetism proposed by Scottish physicist James Clerk Maxwell in 1865. Maxwell proposed that light itself was a series of electromagnetic waves and this prompted Hertz to construct his own apparatus to generate electromagnetic radiation.

Hertz did this in 1886 with a radio wave transmitter using a high voltage induction coil, a condenser, and a spark gap.

But he also had to detect the waves, so he built a receiver to detect the oscillating current. This was visible through the sparks across the spark gap. In later experiments with electromagnetic waves, Hertz determined that the radiation’s velocity was the same as light’s velocity and that radio waves’ reflection and refraction was also the same as light.

The “Hertz,” a universal measure of frequency, was established in 1930.

Today’s Google Doodle celebrates what would be his 155th birthday, Hertz Died at the age of 36.

Honoring The Two-Time Nobel Prize Winner Marie Curie On Her 144th Birthday!

 

To honor one of the most enduringly inspiring scientists ever to grace a lab, France and Poland declared 2011 to be the Year of Marie Curie.

Now, Google joins the welcome pageant of prominent tributes.

The California company’s search-engine home page on Nov. 7 celebrates the 144th anniversary of Madame Curie’s birth with a pastel-colored “Google Doodle” so evocative of her era.

Curie is the latest science figure to join Google’s pantheon of “Doodled” researchers, including Thomas Edison and “father of genetics” Gregor Mendel and “Vitamin C” scientist Albert Szent-Györgyi.

The laurels accorded Curie are numerous and still accumulating a century after she won her second Nobel Prize — the first of only two people ever to win the prize in multiple fields (the other being Linus Pauling). She was also the first woman ever to win the Nobel, and the first researcher to win in multiple sciences (physics and chemistry). But the breadth and depth and influence of her career — as well as the triumphs and tragedies of her life — paint a much fuller picture of the groundbreaking figure who in a 2009 New Scientist poll was voted “the most inspirational woman in science.”

Born in Warsaw in 1867 as Maria Sklodowska, Curie left her native Poland after she was deemed too poor to marry her would-be fiance, future esteemed mathematician Kazimierz Zorawski. So with her sister’s help, she relocated to France in the 1890s, studying at the University of Paris (Sorbonne) and meeting her scientific “soulmate,” Pierre Curie. As they both studied the science of magnetism, they discovered, too, their own personal magnetic attraction.

Together, Marie and Pierre Curie did pioneering work in radioactivity (a term she coined), working with uranium, isolating radioactive isotopes and discovering the elements radium and polonium — the latter named for her native land.

The Curies shared in the 1903 Nobel for physics, bringing them fame as side by side, they grew their professional and personal lives. They had two daughters before Pierre’s untimely death when he was struck by a horse-drawn vehicle on a rainy street in 1906.

Rendered “wretched” and lonely by the tragedy, Marie Curie poured herself into her work, becoming the first woman to become a Sorbonne professor. In 1911, Curie received her second Nobel, this time for chemistry.

Several years later, during World War I, Curie helped set up mobile field hospitals that featured primitive X-ray equipment to help detect shrapnel in soldiers. She worked in the field with her teenage daughter Irene, who — with her husband, Frederic Joliot-Curie — would later win the 1935 chemistry Nobel for her work on artificial radioactivity.

Exposed to so many radioactive materials throughout her career, Marie Curie died of aplastic anemia in 1934.

In addition to her many honors, she founded the Curie Institutes in France and Poland; co-founded the Warsaw Radium Institute; and headed the Pasteur Institute.

Curie’s accomplishments in the lab led to her being interred (with her husband) at the Pantheon, Paris — the first woman so honored based on her work.

Curie helped forever change not only how science thought about radioactivity, but also how the world perceived women in science.

Happy birthday, Madame Curie.
