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.
The Large Hadron Collider is a superstar in the physics world, if only because it’s one of the few physics tools that have crossed over into mainstream consciousness. Basically everyone is aware of the LHC, thanks to the comic books and pop-up children’s books and
First postulated by Peter Higgs in 1964, the Higgs boson is the lynchpin to the unified theory of physics, which states that all matter is composed ultimately of the same subatomic materials organized in a different way. The Higgs boson, according to scientists and the current theory, is the reason why we have elements and materials and all the things we take for granted (because we are composed of them). The Higgs is the glue that holds together subatomic particles.
This may be the first real evidence of the Higgs boson, and it’s all thanks to the world-threatening LHC.
“Some say the world will end in fire, some say in ice…”
What will be the final destiny of the Universe? Probably it will end in ice, if we are to believe this year’s Nobel Laureates in Physics. They have studied several dozen exploding stars, called supernovae, and discovered that the Universe is expanding at an ever-accelerating rate. The discovery came as a complete surprise even to the Laureates themselves.
The Nobel Prize in Physics 2011 was awarded “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae” with one half to Saul Perlmutter and the other half jointly to Brian P. Schmidt and Adam G. Riess.
