EINSTEIN AND POINCARE

Conversation:

Topic:

"I'm interested in bending the edges of the spectrum to make the abstract and the concrete hit one another more directly."

 

IN THE MATRIX

Conversation:
[5.17.03]
Topic:

"All these multiverse ideas lead to a remarkable synthesis between cosmology and physics...But they also lead to the extraordinary consequence that we may not be the deepest reality, we may be a simulation. The possibility that we are creations of some supreme, or super-being, blurs the boundary between physics and idealist philosophy, between the natural and the supernatural, and between the relation of mind and multiverse and the possibility that we're in the matrix rather than the physics itself."

 

WHO CARES ABOUT FIREFLIES?

Conversation:
[5.10.03]
Topic:

"We see fantastic examples of synchrony in the natural world all around us. To give a few examples, there were persistent reports when the first Western travelers went to southeast Asia, back to the time of Sir Francis Drake in the 1500s, of spectacular scenes along riverbanks, where thousands upon thousands of fireflies in the trees would all light up and go off simultaneously. These kinds of reports kept coming back to the West, and were published in scientific journals, and people who hadn't seen it couldn't believe it. Scientists said that this is a case of human misperception, that we're seeing patterns that don't exist, or that it's an optical illusion. How could the fireflies, which are not very intelligent creatures, manage to coordinate their flashings in such a spectacular and vast way?"

 

THE CYCLIC UNIVERSE: PAUL STEINHARDT

Conversation:
[11.19.02]
Topic:

"...in the last year I've been involved in the development of an alternative theory that turns the cosmic history topsy-turvy. All the events that created the important features of our universe occur in a different order, by different physics, at different times, over different time scales—and yet this model seems capable of reproducing all of the successful predictions of the consensus picture with the same exquisite detail."

 

THE INFLATIONARY UNIVERSE: ALAN GUTH

Conversation:
[11.19.02]
Topic:

Inflationary theory itself is a twist on the conventional Big Bang theory. The shortcoming that inflation is intended to fill in is the basic fact that although the Big Bang theory is called the Big Bang theory it is, in fact, not really a theory of a bang at all; it never was.

 

 

THE INTELLIGENT UNIVERSE

Conversation:
[11.5.02]
Topic:

"The universe has been set up in an exquisitely specific way so that evolution could produce the people that are sitting here today and we could use our intelligence to talk about the universe. We see a formidable power in the ability to use our minds and the tools we've created to gather evidence, to use our inferential abilities to develop theories, to test the theories, and to understand the universe at increasingly precise levels."

 

THE EMOTION UNIVERSE: MARVIN MINSKY

Conversation:
[11.5.02]
Topic:

"To say that the universe exists is silly, because it says that the universe is one of the things in the universe. So there's something wrong with questions like, "What caused the Universe to exist?"

 

THE COMPUTATIONAL UNIVERSE

Conversation:
[10.22.02]
Topic:

"Every physical system registers information, and just by evolving in time, by doing its thing, it changes that information, transforms that information, or, if you like, processes that information. Since I've been building quantum computers I've come around to thinking about the world in terms of how it processes information."

 

A GOLDEN AGE OF COSMOLOGY

Conversation:
[12.2.01]
Topic:

Even though cosmology doesn't have that much to do with information It certainly does have to do with revolution and phase transitions, in fact phase transitions in both the literal and the figurative sense of the word.
 

 

A DAY IN THE COUNTRY

Conversation:
[11.18.01]
Topic:

"Physics and everything we know in the world around us may really be tied to processes whose fundamental existence is not here around us, but rather exists in some distant bounding surface like some thin hologram, which by virtue of illuminating it in the right way can reproduce what looks like a 3-dimensional world. Perhaps our three dimensional world is really just a holographic illumination of laws that exist on some thin bounding slice, like that thin little piece of plastic, that thin hologram. It's an amazing idea, and I think is likely to be where physics goes in the next few years or in the next decade, at least when one's talking about quantum gravity or quantum string theory."
