Multiplication table of shapes
I congratulate TaiDanae Bradley for her excellent mathematics blog. In this blogpost she has a wonderful drawing about the multiplication of shapes. “Given any two shapes X and Y, their product X×Y is the shape whose vertical cross sections look … Continue reading

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

Klein’s Quartic Curve Inside Out (animation)
This is from 2005 but geometry is ageless. In week 215 John Baez discussed the Klein’s quartic curve. He mentioned the science fiction author and computer programmer Greg Egan’s work on the visualization of the Klein’s quartic curve. I admired … 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 spacetime 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
