In 4 space dimensions all knots can be unraveled

Nobel laureate Frank Wilczek reminds us in his tutorial article at the Quanta magazine that in 4 space dimensions all knots can be unraveled completely. He explains it as follows: “In three space dimensions, knot theory is a subtle, complicated … Continue reading

Mobius strip representation of spin 1/2

Physics The elementary particles known as fermions (electron, muon, tau and u, d, c, s, b, t quarks ) and their antiparticles are the constituents of matter. A fermion will impart  units of spin angular momentum when it interacts with … Continue reading

Cubic curves

The reason I am interested in cubic curves is that they may be the simplest mathematical representations of the twisting action. In “Prometheus and Chronos” I tried to build a conceptual model of particles based on the hypothesis of intrinsic … Continue reading

Proposals for space-time extensions

Our understanding of the physical universe which is a shadow of the greater Cosmos consisting of spiritual, mental and physical realms is very limited. Our scientific knowledge of the physical universe is growing at an exponential pace but we have only … Continue reading

Phase enables relativity

Physicists are experts at assigning new meanings to the terms established in common language. I mentioned the term “dual” or “duality” before. In common language dual means two. In physics dual means equivalent. Physicists use the word “phase” in different … Continue reading

Dini’s Surface (geometry)

A surface of constant negative curvature obtained by twisting a pseudosphere is known as the Dini’s Surface. It is named after Ulisse Dini. The parametric equations are: x = a cos(u) sin(v) y = a sin(u) sin(v) z = a{cos(v) + … Continue reading
