Amazon is the titan of twenty-first century commerce.
That might seem an odd thing to be optimistic about. Many of my colleagues in physics are inspired by the prospect of achieving a Theory of Everything. My advice, dear colleagues: Be careful what you wish for.
If you reflect for a moment on what the words actually mean, a Theory of Everything may not appear so attractive. It would imply that the world could no longer surprise us, and had no more to teach us. Simply writing down the laws or equations is a long way from being able to anticipate their consequences.
Few physicists—and no sober ones—seriously expect future work in fundamental physics to exhaust, for example, neuroscience. A less literal reading of "Theory of Everything" is closer to what physicists who use it mean by it.
And here "fundamental" is also being used in an unusual, technical sense. A more precise word here might be "basic" or "irreducible". The structure of DNA surely emerges—in principle—from the equations of the standard model, and I strongly suspect that the possibility of Mind does too.
We found—speaking roughly—that we could unify the description of fundamental interactions gauge unification only within an expanded version of relativity, which includes transformations of spin supersymmetry. To make that dual unification we had to bring in new particles, which were too heavy to be observed at the time, but ought to be coming into range at the LHC.
The astronomical riddle of dark matter could well be found there. Several competing ideas are in play, as well. The point is that whatever happens, experimenters will be making fundamental discoveries that take us by surprise.
That would be impossible, if we had a Theory of Everything in the sense just described—that is, of everything fundamental. In recent months a different, much weaker notion of what a "Theory of Everything" might accomplish has gained ground, largely inspired by developments in string theory. In this concept, the Theory provides a unique set of equations, but those equations that have many solutions, which are realized in different parts of the Universe.
One speaks instead of a multiverse, composed of many domains, each forming a universe in itself, each with its own distinctive laws. Now even the fundamental—i. At this point the contrast between the grandeur of the words "Theory of Everything" and the meager information delivered becomes grotesque.
Lest we forget, that quest was fruitless. During his great creative period, Einstein produced marvelous theories of particular things: Brownian motion, the photoelectric effect, the electrodynamics of moving bodies, the equality of inertial and gravitational mass.
I take inspiration from the early Einstein, the creative opportunist who consulted Nature, rather than the later "all-or-nothing" romantic who tried and failed to dictate to Her. Why is that important?
Firstly, because it is true. There is no anthropocentric spite built into the laws of physics, mandating that human improvement may proceed this far and no further.
And secondly, because how we explain failure, both prospectively and retrospectively, is itself a major determinant of success. I knew I should have had a psychological check-up, be tested for delusional fantasies, my PhD revoked in a public ceremony with the breaking of my pencils.
After all, inwe were officially declared "A Nation at Risk". Corporations which depend on rationality for their profits, all agree that our system of 50 independent States, 15, school districts, 26, high schools etc etc has failed catastrophically to educate our students for life and work in the 21st century.
But the good news is that the portent of our failed educational system as it impacts our health care, our economy, our culture and our status in the globalized world is finally becoming clear, clear to parents, clear to economists, clear, gasp! Somehow, we have created a sputnik-like climate warning of a powerful enemy The War on Ignorance.
Out of Sputnik came the National Defense Education Act ofNASA and a renewed determination to modernize science education, but also the conjugate communication skills, foreign languages and a need for public science literacy.
Can one imagine parents who know the earth revolves around the sun?This essay will seek to define Democracy, the meaning of the word, the system and the history, and describe two of the most famous democracies: Direct democracy and Representative democracy.
