Intricacies of Quantum Mechanics for Dummies and the Easier Do-It-Yourself Mechanics

When it comes to reading and understanding the basics of Quantum Mechanics for Dummies one might find his/her brain circuits being fused. It might be confusing at first, but do not think that your physics professor is marbles the next time, when he says that the probability of your position at any particular time in the whole world is never zero. Actually this is where we can start the whole complicated issue of the basics of quantum mechanics for dummies.

The Introduction to Quantum Mechanics for Dummies

According to Niels Bohr, the father of the orthodox ‘Copenhagen Interpretation’ of quantum physics is that, “Anyone who is not shocked by the quantum theory has not understood it”. As observed by a layman, quantum mechanics for dummies appears to be more as a bizarre phenomenon or as a science fiction flick, that is comprised of jargons and complex plus complicated mathematical equations.

Nevertheless, it is a lot easier to take a look at the basics of quantum mechanics for dummies, as long as one is not easily baffled by the simple fact that every electron is a particle, and also a wave in the same given time.

In its definition quantum mechanics is a branch of physics that deals with the study of particles as far as of atomic and sub-atomic levels. Max born in the year 1924 was the one who came up with the term quantum mechanics. J.J Thomson discovered electron in the year 1932, the entire idea of classical physics was shown out to be inapplicable at the atomic level.

The classical physics that was governed by the Newton’s law of motion as well as Maxwell’s law of electro-magnetism was used to define and also to predict the motion of the particles. But this theory failed to explain three critical and world famous experiments below:

The black body radiations: According to the classical theory, a black body would be able to emit infinite amount of energy, which was not true at all. However, Max Plank come up with an equation and developed the Plank’s constant (h) for the energy radiated in the black body emissions.

The photoelectric effect: The photoelectric effect phenomena occur when the electrons are released from certain metals, through the action of light. The electromagnetic theory of light predicts completely different results other than what is recorded through the experiment. Einstein Worked out a formula, using the Plank’s constant ‘h’, for the energy of the electrons emitted in the photoelectric effect in the year 1905.

Finally the optical line spectra: Neils Bohr carried out an experiment in order to study the optical line spectra and come up with the famous Bohr’s model of atom.

All the formulations by these three scientists laid the foundation for the old quantum theory. It was further down the years amended by scientists like W. Heisenberg and E. Schrodinger that it formed the new quantum theory to make Quantum Mechanics for Dummies more simplified.

Basics of Quantum Mechanics for Dummies

Schrodinger’s ‘cat in the box’ experiment: ‘cat in the box’ is a hypothetical experiment, in which a cat is put inside a box with some equipment which on the detection of electrons releases a poisonous gas. Given a case like this one, one would not be in a position to know whether the cat is still alive or is already dead, and this can only be concluded by looking in the box. However, according to the quantum theory, it is better to say whether the cat is half dead or half alive, before checking on it. Getting confused? Essentially, it is all based on the basic assumption of probability and not the fact. Facts, in this case come after actually looking in the box, but until then it’s about probability.

Energy is quantized, that is, in the form of ‘quanta’ or small packets. It may sound illogical but this is the very basic principle that is followed by scientists who work in the field of quantum mechanics.

Moving objects do not possess a well-defined position. It can just be graphically represented, the probability of the existence of the object with respect to the time.

Heisenberg’s principle: states that, the more precisely the energy of an object is known, lesser is the certainty in the calculation of its position in time, and vice-versa. This may also be applicable to the momentum and position of an object.

Quantum mechanics for dummies allows a person to think of the interactions between correlated objects, at a faster pace compared to the speed of the light.  It also lays down the basis of the advanced theory of relativity.

And in addition, the empirical properties of light cannot be explained as long as it is considered to be a wave or a particle. It can only be explained when light is considered to be both a wave as well as a particle.

From Within Quantum Mechanics for Dummies to Without

As highlighted earlier, at this initial stage the brains may get fused while reading about the introduction and the basis of quantum mechanics for dummies.

However, when we come to without it, the do-it-yourself mechanics has been made easier. The author Deanna Sclar has updated systems and repair information all through, eliminating discussions of the carburetors and adding a coverage of hybrid and also alternative fuel vehicles she has also revised the schedules for oil changes and tune ups, it is also including driving tips that can save on repair and maintenance cost, in the do-it-yourself mechanics. In addition, new advise on troubleshooting problems and determining the right time to call in a professional mechanic.

Back to mechanics for dummies, the world in not just what is visible to the naked eyes, but is something that goes far beyond our comprehension. Quantum mechanics has basically revolutionized the study of physics and has opened the gateway for people to see new horizons. As one goes deeper into the intricacies and complexities of the equations, and seeing the application in the real world, one is bound to be fascinated by the study Quantum Mechanics for Dummies.
