Higgs Boson CERN discovery.

The Higgs mechanism had to wait 48 years to be confirmed. Finally during CERN experiment a new particle has been discovered likely to be the Higgs Boson, the so called GOD PARTICLE, responsible to give the Mass to the other particles.

The following VIDEOs illustrates how Higgs Mechanism works and what makes the Higgs Particle so special. 

This is a great achievement in the understanding of how our Universe works.

The Higgs Boson - Illustrative Video

The Higgs Boson has been searched and is still searched in several large experimental groups. The Higgs boson is the elusive subatomic particle which is thought to explain the origins of particle mass, but no one experiment has been able to find it.

The video illustrates what the Higgs Boson is.

The Uncertainty Principle of Quantum Mechanics

The Uncertainty Principle is one of the fundamental laws at the base of Quantum Mechanics. It was postulated by Heisenberg and states precise inequalities that constrain certain pairs of physical properties, such as measuring the present position while determining future momentum.

It introduces also a precise relationship between space, momentum and the Planck constant ħ.


The following video introduces in a simple way the Uncertainty Principle. Enjoy yourself on Fair Science!

The Stern Gerlach Experiment Reveals The Quantum Nature of Matter

With the Stern-Gerlach experiment I started a series of posts where I want to describe in simple terms the quantum nature of reality that surrounds us. The experiment of Stern Gerlach experiment is particularly important because it is not directly understandable in terms of classical mechanics.

In quantum mechanics, the Stern–Gerlach experiment, named after Otto Stern and Walther Gerlach, is an important 1922 experiment on the deflection of particles, often used to illustrate basic principles of quantum mechanics. It can be used to demonstrate that electrons and atoms have intrinsically quantum properties, and how measurement in quantum mechanics affects the system being measured.

Here I present a very explanatory video that allows us to understand what are the differences between the quantum and the macroscopic world described by classical mechanics.

The Double Slit Experiment

The double-slit experiment is a variant of Young's experiment that allows to demonstrate the wave-particle duality of light and matter. Richard Feynman used to say that the heart of quantum mechanics can be understood by reflecting on this experiment.

Quantum Mechanics says that makes no sense to ask a priori the question about what "really" a quantum object is. This is the meaning of the superposition principle which states that wave and particle are just categories of our language by which we describe what we observe in a quantum experiment. Only the experiment shows us the wave or particle nature.

The next video shows the double-slit experiment in a fantastic and very descriptive way.
