In our everyday World we’re used to Absolute deterministic predictions. Throw a ball in the air and it’ll fall along in the trajectory. Leave your umbrella parked on the street. And when you come back, it’s still there. Just one umbrella quantum physics is not like this because quantum mechanics doesn’t allow us to makeContinue reading “Quantum probability: underlying classical variables”

Time Symmetry:The increasing entropy
The basic laws of physics things like F=MA, Gravity is inversely proportional to the distance squared Schrodinger’s equation and so on don’t say anything about the direction of time sure. They relate what’s going on now to what happens next and to what happened previously, but there’s no distinction between forwards and backwards in timeContinue reading “Time Symmetry:The increasing entropy”
Quantum tunneling
Suppose you drop a ball down the side of the valley, Classical wisdom tells us that when the ball rolls up the hill on the other side. It can’t go any higher than the height from which you dropped it that’s conservation of energy. Even if there’s a nice big long slope to roll downContinue reading “Quantum tunneling”
Quarks
When you’re a kid, you’re told that all the stuff around you is made of atoms and that atoms are made of protons and neutrons and electrons. And if you’re lucky you’re told what protons and neutrons are made of they’re made of three quarks eat, but if they’re both made of quarks, how areContinue reading “Quarks”
Brownian motion
One thing that’s astounding about Einstein’s Publications in 1905 is that they spanned a such a large range of physics after Illuminating the quantum nature of Light by explaining the photoelectric effect in March April saw Einstein turn to something apparently more mundane particles suspended in fluids in particular. If you look at tiny particlesContinue reading “Brownian motion”
Gravitational Efficiency: The outrageous efficiency of Blackhole
E=MC², the most famous equation in the world describes the fact that anything with mass possesses a huge amount of energy in principle like a 5-kilogram cat has enough energy in its mass to power the entire country of Norway for a year. If only the energy could somehow be fully extracted from the cat,Continue reading “Gravitational Efficiency: The outrageous efficiency of Blackhole”
Muons:Life example of the theory of relativity
Every second thousand of cosmic rays mostly hydrogen and helium nuclei strike every square meter of the Earth’s upper atmosphere. We don’t really know where they come from. But we do know that when cosmic rays crash into air molecules in the atmosphere. They create a shower of other fundamental particles pions crayons positrons, electronsContinue reading “Muons:Life example of the theory of relativity”
The Universe: constant Conflict
The universe. How big is it? Does it have a center? Does it have an edge? Is it getting bigger? And if so, why well, we know that there are two different meanings for Universe first. The observable universe is everything that we’ve been able to see or observe thus far and second the universeContinue reading “The Universe: constant Conflict”
