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 Higgs Boson the God Particle

The Higgs Boson, called the God Particle, is described in the following video. The Higgs boson is a hypothetical massive elementary particle predicted to exist by the Standard Model of particle physics. The existence of the particle is postulated as a means of resolving inconsistencies in current theoretical physics, and attempts are being made to confirm the existence of the particle by experimentation. Also the Higgs boson is the only Standard Model particle that has not been observed in particle physics experiments. It is a consequence of the so-called Higgs mechanism which is the part of the Standard Model that explains how most of the known elementary particles become massive.

The New Technologies Expected by 2020

The technology that awaits us in the future is amazing. In the next overview we will view, according to the website popsci.com, what are the major technological innovations that lie ahead for future. Popsci.com the year 2020 as a deadline, and innovations technology that should be ready in only 9 years old. Some of Technological innovations that we will be feasible, for others we wait a few more years. If nothing else is a great way to fantasize and imagine how it will be our future.

The Last Shuttle Space Flight

The Shuttle will have the anticipated last launch tomorrow at 3:47 Florida time. NASA will have done all the things well for the last shuttle Endeavour that will take off into the blue.

Thirty years have a certain age for a space program. And the Shuttle that hit the Americans had cooled during the last warm rolls. Hundred and fifty thousand, two hundred thousand spectators just for traffic the last Shuttle.

Nuclear Power Plants

The Nuclear Power Plants interest has increased with the Fukushima nuclear disaster. Nuclear power is produced by controlled nuclear reactions. Commercial and utility plants currently use nuclear fission reactions to heat water to produce steam, which is then used to generate electricity.

But how does it work a Nuclear plant?

The Teleportation Process

Teleportation is the process of more or less instantaneous transport of an object from one place to another, without using conventional means. As a hypothetical teleportation technology is often used in works of fiction, which is generally used as synonymous with instantaneous transport, meaning that the process may also occur over great distances (eg between the Earth and the Moon or another planet) and speeds of or greater than that of light.
Teleportation, as described in fiction, is far from being realized, however, is a major subject of research among physicists around the world who are operating in the field of quantum mechanics.

The teleportation is a theoretical possibility allowed by quantum physics and by the theory of general relativity, two conflicting theories for several other aspects.

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.
