Closing Thought–03Oct18

Ever notice that when the science of Physics is mentioned there is very little thought for the women in the field…….that oversight may well be a thing of the past…..

You see that a woman has finally won the Nobel prize for Physics…..

Three scientists from the United States, France, and Canada have been awarded the Nobel Prize in physics for advances in laser physics, including the first woman to take home the prize in 55 years. The Swedish Royal Academy of Sciences on Tuesday awarded half the $1.01 million prize to Arthur Ashkin of the United States, and the other half will be shared by Gerard Mourou of France and Donna Strickland of Canada, per the AP. Strickland is the third female laureate in physics, but the first in more than half a century, reports the BBC.

The academy says Ashkin developed “optical tweezers” that can grab tiny particles such as viruses without damaging them. As the Guardian notes, “this means scientists can hold even living cells in place, allowing them to probe their inner workings.” Strickland and Mourou helped develop short and intense laser pulses that have broad industrial and medical applications. The Nobel panel’s explanation: “Ultra-sharp laser beams make it possible to cut or drill holes in various materials extremely precisely—even in living matter. Millions of eye operations are performed every year with the sharpest of laser beams.” (A CERN scientist just got suspended for saying physics was built by men.)

Congrats to Ashkin for her award…..a much deserved one at that.

I must be off like a dirty shirt…..see ya later….chuq

GOD Is Found!

First, I did not know he was missing…….Well at least the particle has been found…..

It is the weekend (again) and time to indulge my relief valve and post on something besides the politics du jour……this weekend it will be good sciencey stuff…..

Found while reading “talking Points Memo or TPM………

GENEVA (AP) — The search is all but over for a subatomic particle that is a crucial building block of the universe.

Physicists announced Thursday they believe they have discovered the subatomic particle predicted nearly a half-century ago, which will go a long way toward explaining what gives electrons and all matter in the universe size and shape.

The elusive particle, called a Higgs boson, was predicted in 1964 to help fill in our understanding of the creation of the universe, which many theorize occurred in a massive explosion known as the Big Bang. The particle was named for Peter Higgs, one of the physicists who proposed its existence, but it later became popularly known as the “God particle.”

Last July, scientists at CERN, the Geneva-based European Organization for Nuclear Research, announced finding a particle they described as Higgs-like, but they stopped short of saying conclusively that it was the same particle or some version of it.

Scientists have now finished going through the entire set of data year and announced the results in a statement and at a physics conference in the Italian Alps.

“To me it is clear that we are dealing with a Higgs boson, though we still have a long way to go to know what kind of Higgs boson it is,” said Joe Incandela, a physicist who heads one of the two main teams at CERN that each involve about 3,000 scientists.

But, it remains an “open question,” CERN said in a statement, whether this is the Higgs boson that was expected in the original formulation, or possibly the lightest of several predicted in some theories that go beyond that model.

But for now, it said, there can be little doubt that a Higgs boson does exist, in some form.

Whether or not it is a Higgs boson is demonstrated by how it interacts with other particles and its quantum properties, CERN said in the statement. The data “strongly indicates that it is a Higgs boson,” it said.

The discovery would be a strong contender for the Nobel Prize, though it remains unclear whether that might go to Higgs and the others who first proposed the theory or to the thousands of scientists who found it, or to all of them.

The hunt for the Higgs entailed the use of CERN’s atom smasher, the Large Hadron Collider, which cost some $10 billion to build and run in a 17-mile (27-kilometer) tunnel beneath the Swiss-French border.

It has been creating high-energy collisions to smash protons and then study the collisions and determine how subatomic particles acquire mass — without which the particles would fail to stick together.

If so I smell a Nobel for some lucky person…….but what will this mean to humanity?  Thoughts?
