I would stand up at conferences and have people almost throwing rotten tomatoes at me.

His offence was to be an ardent advocate of a then controversial idea - that most of the universe’s matter comes as a cold, heavy soup of invisible “dark matter”. Today that is the orthodoxy.  [New Scientist]

For There We Are Captured—-The Geometry of Spacetime


What does it mean when we say spacetime is “curved” or “flat?”


The answer lies in the interface between differential geometry and physics.

The geometry of spacetime is more complex than we might imagine. The same can be said about quantum geometry.

There is no reason to believe that our brains are matched to understanding every level of reality

Martin Rees (born 1942)

“A chimpanzee can’t understand quantum mechanics,” Rees points out.

That might sound like a statement of the obvious. After all, as Richard Feynman famously said, nobody understands quantum mechanics. The point, though, is that chimps don’t even know what they don’t understand. “It’s not that a chimpanzee is struggling to understand quantum mechanics,” Rees says. “It’s not even aware of it.” The question that intrigues Rees is whether there are facets of the universe to which we humans are similarly oblivious.

Chaos theory
 
sciencenote:


A mathematical concept that explains that it is possible to get random results from normal equations. The main precept behind this theory is the underlying notion of small occurrences significantly affecting the outcomes of seemingly unrelated events.
 Chaos theory has been applied to many different things, from predicting weather patterns to the stock market. Simply put, chaos theory is an attempt to see and understand the underlying order of complex systems that may appear to be without order at first glance.

Solvay Physics Conference 1927

 

Perhaps the most famous [Solvay] conference was the October 1927 Fifth Solvay International Conference on Electrons and Photons, where the world’s most notable physicists met to discuss the newly formulated quantum theory. The leading figures were Albert Einstein and Niels Bohr. Einstein, disenchanted with Heisenberg’s uncertainty principle, remarked “God does not play dice”. Bohr replied, “Einstein, stop telling God what to do”. (See Bohr–Einstein debates.) 17 of the 29 attendees were or became Nobel Prize winners, including Marie Curie, who alone among them, had won Nobel Prizes in two separate scientific disciplines.

This conference was also the culmination of the struggle between Einstein and the scientific realists, who wanted strict rules of scientific method as laid out by Charles Peirce and Karl Popper, versus Bohr and the instrumentalists, who wanted looser rules based on outcomes. Starting at this point, the instrumentalists won, instrumentalism having been seen as the norm ever since, although the debate has been actively continued by the likes of Alan Musgrave.

Twenty-nine physicists, the main quantum theorists of the day, came together to discuss the topic “Electrons and Photons”. Seventeen of the 29 attendees were or would become Nobel Prize winners.

Among the most famous participants in the conference were Erwin Schrodinger, Niels Bohr, Werner Heisenberg, Auguste Piccard, Paul Dirac, Max Born, Wolfgang Pauli, Louis de Broglie, Marie Curie, Hendrik LorentzHans Kramers, and Albert Einstein.

These men - particularly Bohr, Heisenberg, Kramers, Dirac and Born together with de Broglie - represent the founding fathers of quantum mechanics.

The film opens with quick shots of Erwin Schrodinger and Niels Bohr. Auguste Piccard of the University of Brussels follows and then the camera re-focuses on Schrodinger and Bohr.

Following the newsreel is a “home movie” shot by Irving Langmuir, (the 1932 Nobel Prize winner in chemistry). It captures 2 minutes of an intermission in the proceedings. Twenty-one of the 29 attendees are on the film.
