What Einstein might have Missed

Einstein

Apparently Einstein died wishing he knew more math. Actually he should have investigated the very foundations of mathematics.

Mathematics is a subject that is extremely consistent. One is not going to find any inconsistency in math. But Einstein should have been curious about the ideas on which mathematics is based. 

The Foundations of Mathematics

Einstein struggled to understand Quantum Mechanics all his life. He felt a fundamental disagreement with its basis but he could not put his finger on it.

Experimentations at quantum level have shown that there is wave-particle duality. This means that there is no such thing as a “point-particle.” Yet the quantum theory still looks for a point-particle in terms of probability through a wave function.

Maybe it is not a point-particle that is being assumed. Maybe it is a “point-location” and a “point-time” that is being taken for granted. This is possible because mathematics itself is founded on the ideas of “point” and “unit.” The truth is that our very thinking is constructed upon the ideas of “point” and “unit.” Mathematics is simply a refinement of logic.

Quantum Mechanics shows us that the classical thinking is no longer valid. The mass of a particle cannot be reduced to a precise center of mass . Nor is there an ideal disturbance with no center of mass. Infinite sine and cosine wave representations of disturbance are mathematical constructs only. The truth is somewhere in between. the center of mass gets increasingly diffused as we investigate the quantum levels.

The inconsistency seems to be that space and time are still being perceived as independent of the disturbance (wave) and the mass (particle). It is being believed that there is a “point-location” and a “point-time” even when there is no “point-particle.” Looks like reality is being confused with mathematical thinking.

Can the very space and time be “diffused” like the quantum “particle”?

Maybe space and time are not independent of disturbance and mass. Maybe space and time are as diffused at quantum levels as are the observations of waves and particles.

The Known Universe by AMNH

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world’s most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

Einstein & New Thinking

Einstein

“A human being is part of the whole called by us Universe, a part limited in time and space.

“We experience ourselves, our thoughts and feelings, as something separate from the rest. A kind of optical delusion of consciousness…

“This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.

“Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty…

“The true value of human beings is determined primarily by the measure and the sense in which they have obtained liberation from the self…

“We shall require a substantially new manner of thinking if humanity is to survive.”

(Albert Einstein, 1954)
