On value of David Bohm’s Quantum Mechanics

Abstract

The Templeton Prize winner wrote: „In the second half of the eighteenth century, the deterministic character of Newton’s equations encouraged many people to see the physical world in strictly mechanical terms, as if the universe is a gigantic piece of cosmic clockwork.” Such wrong view comes from the believe, that the energy and momentum are always conserve.

Quantum revolution

CERN Bulletin

The turn of the XXth century witnessed a revolution in physics comparable to Isaac Newton’s discovery of the universal laws of mechanics and of gravitation three centuries earlier. The world required to be described in novel terms, as the immutable, deterministic view of our familiar universe had given way to a new world picture, one which featured chance, flux, and an incessant upsurge of waves of matter. Such a worldview was so radically new and counterintuitive that it gave rise to strong debates, to the effect that Albert Einstein himself tried to oppose it on the grounds that “God does not play dice”. In spite of the intense debates that accompanied its emergence, quantum mechanics quickly proved an incredibly efficacious new tool to understand and to predict a wide array of new phenomena. It was so successful that in no time it broke free from the environment of research labs to become part of daily life, making it possible, for example, to understand why some materials were conductors, while others were insulators. Along with it, came, too, the discovery of transistors, on which much of modern electronics rests. It also led to understand how novel materials known as superconductors allow the transport of electricity with no loss, thus paving the way for new developments in the fields of medical imagery or energy distribution. Other aspects of the quantum theory led to the development of atomic clocks of astounding accuracy, which would be wrong by no more than fifteen seconds, had they been set at the beginning of the universe. A hundred years later, at the turn of the XXIst century, Quantum mechanics has lost none of its astounding power. Contemporary research has undertaken the task of exploring its less immediately perceptible aspects. Groundbreaking developments have ensued, such as the teleportation of grains of light or the possibility, once predicted by the great physicist Richard Feynman, to build, one day, novel computers which, unlike the ones we are familiar with today, will be able to process innumerable numbers of operations in parallel. The Wright Colloquium will be for us the occasion to explore, in the company of five internationallyknown specialists in the field, some of the fascinating aspects of quantum mechanics. We will appraise how efficiently quantum physics can describe our world, and confront its limitation when it is faced with the infinitely small (in relation to recent experiments carried out at the CERN) as with the incommensurably large scale of sidereal spaces. We will appreciate the extent to which quantum physics already has impacted our everyday lives, and evoke the way in which novel fields such as quantum computers and quantum information will entail profound changes in the future. The quantum adventure has only just begun!

Wonderful, Wonderful Copenhagen

Bruce Rosenblum, Fred Kuttner

Abstract The meaning of Newton’s mechanics was clear. It described a reasonable world, a “clockwork universe.” It needed no interpretation. Einstein’s relativity is surely counterintuitive, but no one interprets relativity. We come to accept the idea that moving clocks run slow. It’s harder to accept that observation creates the reality observed. That needs interpretation.

The Path Not Taken

Michael G. Munowitz

The quantum mechanical superposition state — the wave function — takes shape, and the rules for its deterministic evolution and probabilistic interpretation are developed. A clockwork macrocosm in which the Moon never wavers from its course gives way to a guesswork microcosm in which an electron follows no predetermined path at all. This leads to a quantum mechanical world in which the sharp values of position, velocity, momentum, energy, and all the other quantities of classical mechanics blur into the probability distributions of quantum mechanics.

Bohmian Mechanics and Bouncing Universes

G. Moultaka

Quoting James Cushing (1994): '... most will never have heard of Bohm's theory. Those who have are certain it must be wrong, although they are not sure exactly why...Those few who still remain to listen to a description of Bohm's theory are usually surprised when they learn that they can, if they wish, consistently believe in actual particle trajectories in a space-time background.'In this talk we present the main features of the de Broglie-Bohm quantum mechanics from a perspective where it could provide a path to new physics, where the orthodox approach to quantum mechanics would be an effective description of a more fundamental underlying theory.

A philosopher looks at quantum mechanics

Hilary Putnam

Those defile the purity of mathematical and philosophical truthy who confound real quantities with their relations and sensible measures. —ISAAC NEWTON, Principia Before we say anything about quantum mechanics, let us take a quick look at the Newtonian (or ‘classical’) view of the physical universe. According to that view, nature consists of an enormous number of particles. When Newtonian physics is combined with the theory of the electromagnetic field, it becomes convenient to think of these particles as dimensionless (even if there is a kind of conceptual strain involved in trying to think of something as having a mass but not any size ), and as possessing electrical properties – negative charge, or positive charge, or neutrality. This leads to the well-known ‘solar system’ view of the atom – with the electrons whirling around the nucleons (neutrons and protons) just as the planets whirl around the sun. Out of atoms are built molecules; out of molecules, macroscopic objects, scaling from dust motes to whole planets and stars. These latter also fall into larger groupings – solar systems and galaxies – but these larger structures differ from the ones previously mentioned in being held together exclusively by gravitational forces. At every level, however, one has trajectories (ultimately that means the possibility of continuously tracing the movements of the elementary particles) and one has causality (ultimately that means the possibility of extrapolating from the history of the universe up to a given time to its whole sequence of future states).

The Quantum Wavefunction

Nagaganesh Jaladanki

When most people think of physics, they think of what they learned in high school physics: that the world is fundamentally predictable. Given the position and velocity of a particle in space, it should be possible to predict its position at any moment in the future, right? Though this was thought to be true for thousands of years, recent developments in the field of physics have shown that this isn't actually true. Instead of being fundamentally predictable, the universe is fundamentally unpredictable. However, this doesn't seem to make sense. What happened to the centuries of physics developed by Newton, Bernoulli, and Lagrange? Well, as it turns out, they weren't actually wrong. Their equations were actually an approximation of a formula called the wavefunction, which is the "Newton's Laws" equivalent for modern physics. In this paper, we'll take a look at this peculiar wavefunction and why our intuition about the world is completely wrong.
