Re: Parallel Universe 2008

Forget tennis. I was watching PBS Nova last evening and who would have ever thought the context would be about the following: ( Excerpt from "Parallel Worlds,Parallel Lives)

TV Program Description
Original PBS Broadcast Date: October 21, 2008
For most of Mark Oliver Everett's life, things didn't add up. "Parallel Worlds, Parallel Lives" follows Mark, better known as E, the lead singer of the rock band EELS, across the country as he attempts to understand the fantastic possibility of parallel universes and unravel the story of his troubled family and the father he never really knew—iconoclastic quantum physicist Hugh Everett III.

Scientific American described Hugh Everett as "one of the most important scientists of the 20th century." In 1957, he proposed the controversial Many Worlds Theory, a startling interpretation of quantum mechanics. The theory makes the astounding prediction that parallel universes are constantly splitting off from our everyday reality. For many years, Hugh Everett's mind-boggling theory was overlooked. Today, the concept of parallel universes is not only explored by many top physicists, but it also inspired many films, television series, and books, including The Golden Compass, Star Trek, and The Subtle Knife. (See Science Fiction and Fact for more on this parallel evolution of ideas.)

In this intelligent and imaginative film, the wry and charismatic Mark takes an emotional journey into his father's life, meeting Hugh's old college friends, colleagues, and admirers, including MIT physicist Max Tegmark, a vocal proponent of Hugh's ideas. It is only by entering the esoteric world of quantum physics that Mark can hope to gain an understanding of, and more importantly, a connection to the father who was a stranger to him.

Hugh Everett published his theory of parallel universes over 50 years ago as a Ph.D. student at Princeton University. (See an expanded version of Hugh's dissertation as well as two related original documents he wrote.) But it remained largely ignored by the scientific community for 20 years. Hugh's hypothesis countered the Copenhagen Interpretation, the most widely accepted view of the many puzzles of quantum physics, developed by Nobel laureate Niels Bohr. At that time, many considered the ambitious 24-year-old extremely naive and arrogant to challenge Bohr, who rivaled Albert Einstein as one of the giants of the physics world. (Learn more about the theory in an interview with Hugh's biographer, Peter Byrne.)

Through interviews and archival materials, the film conveys how Bohr's disregard of Everett's work devastated the young scientist. Dejected and depressed, he left quantum physics behind and became a defense analyst, conducting classified research for the Pentagon. Later he joined the corporate world, applying mathematical modelling in industry. The chain-smoking, hard-drinking Hugh Everett died of a heart attack in his Virginia home, long before Mark could appreciate his father's professional triumphs and frustrations.

"My father never, ever said anything to me about his theories," Mark says. "I was in the same house with him for at least 18 years, but he was a total stranger to me. He was in his own parallel universe. He was a physical presence, like the furniture, sitting there jotting down crazy notations at the dining room table night after night. I think he was deeply disappointed that he knew he was a genius but the rest of the world didn't know it."

Mark Everett jokingly admits that he can barely tabulate a restaurant tip, let alone understand his father's complex ideas. While Hugh focused on science, Mark focused on music. He mastered the piano, drums, and guitar, and became an accomplished songwriter. In addition to writing material for their award-winning albums, EELS contributed songs to movie soundtracks, including How the Grinch Stole Christmas and the three animated Shrek films.

Now in his forties, Mark is the sole surviving member of his family, which he has described as strange and lonely. With an intimate, often quirky style, "Parallel Worlds, Parallel Lives" delves deep into the Everett's family history, including the bouts of mental illness. Mark's father and paternal grandmother both suffered from severe depression, as did his deeply troubled sister. The making of this documentary reintroduced Mark Everett to his father and helped him understand his dreams and disappointments. (Read Finding My Father, an excerpt from Mark's newly published autobiography.)

"I feel like I know my father a lot better," Mark says. "I feel I understand more of the whole time line of events. Just talking to all these people who knew him, it feels like he's around now more than ever before."

Re: Parallel Universe 2008

Happy 2009 everyone. May this universe now fall into the black hole of history.

Happy New Year back to you, and all tennis fans in both Universes, no surprises today, Murray routines Blake and Davydenko edges Roddick. That book sounds like a good read, I may look into it

Re: Parallel Universe 2008

Bump! Seems IW has a history ( at least on this thread if my memory serves me correctly ) of causing upsets.

2012- IW has already seen in early rounds top seeds in Doubles and Murray. I would just love love love it if someone other than the big 4 win this Masters.

Re: Parallel Universe 2008 And Now 2012!

So the Williams sisters will meet again at the Wimbledon finals? Ooops, I forgot this is an ATP forum.

Re: Parallel Universe 2008 And Now 2012!

I just had to bump this thread in honor of those not posting here anymore but who made MTF such a fun place. And this news story is just too good to pass up in keeping with the title. So if science ever proves a parallel universe hope is eternal. But wait- of course we will never ever know the parallel universe

Schrödinger's Cat could be visible after all
Posted March 4, 2013 - 05:41 by Emma Woollacott
Schrödinger's Cat could be (almost) as easy to observe as the internet's millions of LOLcats, with confirmation that there may be a way round Heisenberg's famous Uncertainty Principle after all.

Researchers at the University of Rochester and the University of Ottawa have used a comparatively new technique to directly measure for the first time the polarization states of light. Their work has implications for the weird Uncertainty Principle, which states that certain properties of a quantum system can be known only poorly if other related properties are known precisely.

The direct measurement technique was first developed in 2011 by scientists at Canada's National Research Council to measure the wavefunction - a way of determining the state of a quantum system. Such direct measurement had long been believed to be impossible on the basis that you could never fully understand a quantum system through direct observation.

Now, the Canadian researchers have come up with a parallel result - that it is possible to measure key related variables, known as 'conjugate' variables, of a quantum particle or state directly. The discovery is applicable to qubits, the building blocks of quantum information theory, as polarization states of light can be used to encode information.

"The ability to perform direct measurement of the quantum wavefunction has important future implications for quantum information science," says Robert Boyd, of both Rochester and Ottawa. "Ongoing work in our group involves applying this technique to other systems, for example, measuring the form of a 'mixed' (as opposed to a pure) quantum state."

The direct measurement technique employs a clever trick to measure the first property in such a 'weak' way that the system isn't disturbed significantly, and information about the second property can still be obtained.

Boyd and his team did this by passing polarized light through two crystals of differing thicknesses: the first, a very thin crystal that 'weakly' measured the horizontal and vertical polarization state; the second, a much thicker crystal that 'strongly' measured the diagonal and anti-diagonal polarization state.

As the first measurement was performed weakly, the system wasn't significantly disturbed, meaning that information gained from the second measurement was still valid. Repeating the process several times allows accurate statistics to be built up, giving a full, direct characterization of the polarization states of the light.
