Publisher's Summary

"Everything is energy": The mysterious reasons why only 0.0001 percent of humans really understand this principle, and how applying it every day in your life will let you get everything you desire....

In today's society, it is increasingly on the agenda to reason by stereotypes. The continuous distractions and surplus of information are leading us to an increasingly elusive and superficial perception of the world. Only a few discerning people are engaged in a careful and in-depth analysis of reality.

"Things are not always as they seem," says the famous Gibran, and quantum physics unquestionably sanctions the truth of this famous thought.

Einstein, Planck, Heisenberg, and Bohr (just to mention the most famous) were courageous visionaries - careful observers who did not stop at appearances and what the world of conventions proposed to them as absolute realities. This value was reciprocated with a revolutionary conception of life, which in some cases, for the weakest of hearts, led to madness. But for the most valiant, it was the keystone that allowed them to get everything they wanted out of their lives.

How strong is your heart?

In this essential guide to quantum physics, I will explain the most complex concepts in a very simple and understandable way, with the help of practical and immediate examples. Not only that, I will reveal to you the most intricate and hidden (in the worst mathematical formulas), real and tangible implications that you can apply in everyday life, giving you the opportunity to literally make a quantum leap.

Now for a little taste of what you will find inside this wonderful essay:

  • Where it all began
  • The basic concepts of quantum physics
  • The mysterious adventures of Einstein
  • Wormholes, time, and the fourth dimension: What do they have in common?
  • Where will relativity take us in the third millennium?
  • Light: Do you really know what it is?
  • What was hidden in Heisenberg's mind? 
  • And much more...

Learn concepts worthy of an excellent mind without effort, understand the most revolutionary and mysterious rules that govern the universe in which you live. Observe and interpret the reality that surrounds you with Einstein's eyes and change your life by catapulting it light years away from oppressive ordinariness. Don't wait any longer than you have already done to get hold of the keystone.... Act now!

Language of quantum

Einstein and his dissident colleagues were faced with our own difficulty, that is, to understand the new atomic physics through the vocabulary and philosophy of macroscopic objects. We have to learn to understand that the world of Newton and Maxwell finds itself as a consequence of the new theory, which is expressed in the quantum language. If we were also as big as atoms, we would have grown up surrounded by phenomena that would be familiar to us; and maybe one day an alien as big as a quark would ask us: "What kind of world do you think we get if we put together 1023 atoms and form an object that I call "ball"? Perhaps it is the concepts of probability and indeterminacy that challenge our linguistic abilities. This is no small problem that remains in our day and frustrates even great minds. It is said that the famous theoretical physicist Richard Feynman refused to answer a journalist who, during an interview, asked him to explain to the public what force was acting between two magnets, claiming that it was an impossible task. Later, when asked for clarification, he said it was because of intuitive preconceptions. The journalist and a large part of the audience understand "force" as what we feel if we reward the palm of your hand against the table. This is their world, and their language. But in reality in the act of supporting the hand are involved electromagnetic forces, the cohesion of matter, quantum mechanics - it is very complicated. It was not possible to explain the pure magnetic force in familiar terms to the inhabitants of the "old world". As we will see, to understand quantum theory we must enter a new world. It is certainly the most important fruit of the scientific explorations of the twentieth century, and it will be essential for the whole new century. It is not right to let only professionals enjoy it.

This course is an excellent way to learn a new way to live and to respond to our universe...to nature and others.
Over all, a great course.

No math, promised, but just a few numbers

With this audiobook we would like to give you an idea of the tools that physics has developed to try to understand the strange microscopic world inhabited by atoms and molecules. We ask readers only two small efforts: to have a healthy sense of curiosity about the world and to master the advanced techniques for solving differential equations with partial derivatives. All right, we joked. After years of giving elementary physics courses to students of non-scientific faculties, we know how widespread the terror of mathematics is among the population. No formulas, then, or at least the minimum necessary, few and scattered here and there. The scientific vision of the world should be taught to everyone. Quantum mechanics, in particular, is the most radical change of perspective occurred in human thought since the ancient Greeks began to abandon the myth in favor of the search for rational principles in the universe. Thanks to the new theory, our understanding of the world has greatly expanded. The price paid by modern science for this broadening of intellectual horizons has been the acceptance of many apparently counterintuitive ideas.

But remember that the blame for this falls mainly on the shoulders of our old Newtonian language, unable to accurately describe the atomic world. As scientists, we promise to do our best Since we are about to enter the realm of the infinitely small, it is convenient for us to use the convenient notation of the "powers of ten".

James Fradkov Makes Q.M. Doable

In general, does not notice if what surrounds us is moving at the same speed as us, and if the motion is uniform and not accelerated we do not feel any sensation of displacement. The Greeks believed that there was a state of absolute rest, relative to the surface of the Earth. Galileo questioned this venerable Aristotelian idea and replaced it with a more scientific one: for physics there is no difference between standing still and moving with constant (even approximate) direction and speed. From their point of view, astronauts are standing still; seen from Earth, they are circling us at a crazy speed of 28 800 kilometers per hour. Galileo's sharpened ingenuity easily understood that two bodies of different weights fall at the same speed and reach the ground at the same time. For almost all his contemporaries, however, it was anything but obvious, because daily experience seemed to say otherwise. But the scientist did the right experiments to prove his thesis and also found a rational justification: it was the resistance of the air that shuffled the cards. For Galileo this was only a complicating factor, which hid the deep underlying simplicity of natural laws. Without air between the feet, all bodies fall with the same speed, from the feather to the colossal rock. It was then discovered that the gravitational attraction of the Earth, which is a force, depends on the mass of the falling object, where mass is a measure of the amount of matter contained in the object itself.

The bridge between science and spirituality

In the 21st century quantum mechanics has become the backbone of all the research in the atomic and subatomic world, as well as of wide sectors of material sciences and cosmology. The fruits of the new physics make thousands of billions of dollars every year, thanks to the electronics industry, and as many follow from the improvements in efficiency and productivity made possible by the systematic use of quantum laws. Some physicists a bit rebellious, however, driven by the cheers of a certain type of philosophers, still continues to seek a deeper meaning, a principle hidden within quantum mechanics in which determinism is found. But it is a minority. Why is quantum physics disturbing, from a psychological point of view? In a famous passage of a letter to Max Born, Einstein wrote: "You believe that God plays dice with the world, I believe instead that everything obeys a law, in a world of objective reality that I try to grasp through furiously speculative. Not even the great initial success of quantum theory manages to convince me that at the basis of everything there is randomness, although I know that younger colleagues consider this attitude as an effect of sclerosis. 3 Erwin Schrödinger thought in a similar way: "If I had known that my wave equation would be used in this way, I would have burned the article before publishing it [...] I don't like it and I regret having had anything to do with it".4 What disturbed these eminent figures, so much so that they were forced to deny their beautiful creation? Let us go into a little detail about these lamentations, in Einstein's protest against a God who "plays dice". The turning point of modern quantum theory dates back to 1925, precisely to the solitary vacation that the young German physicist Werner Heisenberg spent in Helgoland, a small island in the North Sea where he had retired to find relief from hay fever. There he had a revolutionary idea.5

Interesting thoughts.

Planck was one of the greatest theoretical physicists active at the turn of the century, and even he did not like the fold that quantum theory had taken. It was the supreme paradox, since he had been the true founder of the new physics, besides having coined the term "how much" already at the end of the nineteenth century. We can perhaps understand the scientist that speaks of "betrayal" about the entry of the probability in the physical laws instead of the solid certainties of cause and effect. Let's imagine having a normal tennis ball and bouncing it against a smooth concrete wall. We do not move from the point where we threw it and continue to hit it with the same force and aiming in the same direction. Under the same boundary conditions (such as wind), a good tennis player should be able to get the ball in exactly the same place, shot after shot, until he gets tired or the ball (or the wall) breaks. A champion like Andre Agassi counted on these characteristics of the physical world to develop in training the skills that allowed him to win Wimbledon. But what would happen if the rebound was not predictable? Or if even on some occasion the ball was able to cross the wall? What if only the probability of the phenomenon is known? For example, fifty-five times out of a hundred the ball goes back, the other forty-five times it goes through the wall. And so on, for everything: there is also a probability that it will cross the barrier formed by the racket. We know that this never happens in the macroscopic and Newtonian world of tennis tournaments. But at the atomic level everything changes. An electron shot against the equivalent of a particle wall has a probability different from zero to cross it, thanks to a property known as "tunnel effect". Imagine what kind of difficulties and frustrations would meet a tennis player engaged in the subatomic world.

concise and clear exposition of quantum physics.

To really understand the behavior of atoms, to create a theory that would agree with the seemingly contradictory data that came out of the laboratories in the thirty years between 1900 and 1930, it was necessary to act in a radical way, with a new audacity. The equations, which until then calculated with precision the dynamics of events, became tools to obtain fans of possibilities, each of which could happen with a given probability. Newton's laws, with their certainties (so we speak of "classical determinism") were replaced by Schrödinger's equations and Heisenberg's disconcerting mathematical constructions, which spoke the language of indeterminacy and nuance. How does this uncertainty manifest itself in nature, at the atomic level? In various areas, of which here we can give a first, simple example. Atomic physics tells us that given a certain amount of radioactive material, let's say uranium, half will transform thanks to a process called "decay" and will disappear before a fixed period of time, called "half-life" or "half-life". After another time interval equal to the half-life, the remaining atoms will be reduced another time by half (so after a time as long as two halflives the amount of uranium present at the beginning will be reduced to a quarter of the original; after three half-lives, to an eighth; and so on).

Thanks to quantum mechanics and some complicated equations, we are able to calculate in principle the value of the half-life of uranium, and of many other fundamental particles. We can put at work arrays of theoretical physicists and get many interesting results. Yet, we are absolutely not able to predict when a certain uranium atom will decay. It is a disconcerting result. If uranium atoms were to follow the laws of classical Newtonian physics, there would be some mechanism at work that, provided we perform the calculations accurately, would allow us to predict exactly when a certain atom will decay. Quantum laws do not offer deterministic mechanisms and give us probability and data blurred not for simple ignorance of the problem, but for deeper reasons: according to the theory, the probability that the decay of that atom happens in a certain period is all we can know.

Quantum physics made simple and fun

Before the quantum era, who observed a phenomenon was like an alien from space, who looked at the Earth from above and noticed only the movements of large crowds of thousands and thousands of people. Maybe they saw them marching in compact ranks, or applauding, or hurrying to work, or scattering in the streets. But nothing they observed could ever prepare them for what they would see by focusing their attention on individuals. On an individual level, humans showed behavior that could not be deduced from that of crowds - things like laughter, affection, compassion and creativity. Aliens, perhaps robotic probes or evolved insects, may not have had the right words to describe what they saw when they observed us closely. On the other hand, even we, today, with all the literature and poetry accumulated over the millennia, sometimes we can not fully understand the individual experiences of other human beings.

How did we get along without this?

At the beginning of the 20th century something similar happened. The complex building of physics, with its exact predictions about the behavior of objects, i.e. crowds of atoms, suddenly collapsed. Thanks to new, sophisticated experiments, conducted with great skill, it was possible to study the properties not only of individual atoms, but also of the smaller particles of which they were made. It was like going from listening to an orchestral ensemble to quartets, trios and solo pieces. And the atoms seemed to behave in a disconcerting way in the eyes of the greatest physicists of the time, who were awakening from the sleep of the classical age. They were explorers of an unprecedented world, the equivalent of the poetic, artistic and musical avant-garde of the time. Among them were the most famous: Heinrich Hertz, Ernest Rutherford, J. J. Thomson, Niels Bohr, Marie Curie, Werner Heisenberg, Erwin Schrödinger, Paul Dirac, Louis-Victor de Broglie, Albert Einstein, Max Born, Max Planck and Wolfgang Pauli. The shock they felt after poking around inside the atoms was equal to what the crew of the Enterprise must have experienced when they first encountered an alien civilization found in the vastness of the cosmos. The confusion produced by the examination of the new data slowly stimulated the first, desperate attempts by physicists to restore some order and logic in their science. At the end of the twenties of the last century the fundamental structure of the atom could be said by now known in broad lines, and it could be applied to the chemistry and physics of ordinary matter. Mankind had begun to really understand what was happening in the new, bizarre quantum world. But while the crew of the Enterprise could always be teleported away from the most hostile worlds, the physicists of the early twentieth century did not go back: they realized that the strange laws they were discovering were fundamental and were the basis of the behavior of all matter in the universe.

Since everything, including humans, is made of atoms, it is impossible to escape the consequences of what happens at the atomic level. We have discovered an alien world, and that world is within us! The shocking consequences of their discoveries upset not a few scientists of the time. A bit like revolutionary ideologies, quantum physics consumed many of its prophets. In this case the ruin did not come from political machinations or conspiracies of adversaries, but from disconcerting and deep philosophical problems that had to do with the idea of reality. When, towards the end of the 1920s, it became clear to everyone that a real revolution had occurred in physics, many of those who had given it the initial impetus, including a figure of the caliber of Albert Einstein, repented and turned their backs on the theory they had contributed significantly to creating.

Yet today, well underway in the 21st century, we use quantum physics and apply it to a thousand situations. Thanks to her we have invented for example transistors, lasers, atomic energy and countless other things. Some physicists, even prominent ones, continue to use all their strength to find a version of quantum mechanics softer for our common sense, less destructive than the common idea of reality. But it would be good to reckon with science, not with some palliative.

A new Dimension

In 1925, completely independent from Heisenberg's ideas, another theoretical physicist had another fundamental idea, also while he was on vacation (not alone, however). It was the Viennese Erwin Schrödinger, who had formed a bond of friendship and scientific collaboration with his colleague Hermann Weyl. The latter was a mathematician of great value, who had a decisive role in the development of the relativity theory and in the relativistic version of the electron theory. Weyl helped Schrödinger with the calculations and as compensation he could sleep with his wife Anny. We do not know what the woman thought about the matter, but social experiments of this kind were not rare in the twilight of the Viennese intellectual society. This agreement also included the possibility for Schrödinger to embark on a thousand extramarital adventures, one of which led (in a certain sense) to a great discovery in the quantum field.7 In December 1925, Schrödinger went on a twenty-day vacation to Arosa, a village in the Swiss Alps. Leaving Anny at home, he was accompanied by an old Viennese flame. In her suitcase she also put a scientific article by her French colleague Louis de Broglie and earplugs. While he was concentrating on the writing, sheltered from annoying noises (and who knows what the lady was doing in the meantime), the idea of the so-called "wave mechanics" came to his mind. It was a new and different way to formalize the emerging quantum theory in mathematically simpler terms, thanks to equations that were well known to the main physicists of the time. This revolutionary idea was of great support for the then fragile quantum theory, which became known to a much greater number of people.8 The new equation, which in honor of its discoverer is called "Schrodinger's equation", on one hand accelerated the path of quantum mechanics, but on the other hand made its inventor crazy because of the way it was interpreted.

It is surprising to read of Schrodinger's repentance, due to the scientific and philosophical revolution triggered by his ideas.

A beginners guide to understanding Physics

Before the quantum era, physics had managed very well to describe the phenomena that happen before our eyes, solving problems in a world made of stairs firmly resting on the walls, arrows and cannonballs launched according to precise trajectories, planets orbiting and rotating on themselves, comets returning to the expected time, steam engines doing their useful work, telegraphs and electric motors. In short, at the beginning of the twentieth century almost every observable and measurable macroscopic phenomenon had found a coherent explanation within the so-called classical physics. But the attempt to apply the same laws to the strange microscopic world of atoms proved incredibly difficult, with deep philosophical implications. The theory that seemed to come out, the quantum theory, went completely against common sense. Our intuition is based on previous experiences, so we can say that even classical science, in this sense, was sometimes counterintuitive, at least for the people of the time. When Galileo discovered the laws of ideal motion in the absence of friction, his ideas were considered extremely daring (in a world where no one or almost no one had thought to neglect the effects of friction).2 But the classical physics that emerged from his intuitions managed to redefine common sense for three centuries, until the 20th century. It seemed a solid theory, resistant to radical changes - until quantum physics burst onto the scene, leading to an existential shock like never before.

One of best

To replicate the showcase situation in an experimental context (and much more expensive), we shoot electrons against a barrier constituted by a grid of conductive wires inside a container where the vacuum is made, connected to the negative pole of a battery with voltage equal, for example, to 10 volts. An electron with energy equivalent to a potential of 9 volt should be reflected, because it cannot counter the repulsive force of the barrier. But Schrödinger's equation tells us that a part of the wave associated to the electron is still able to pass through it, just as it happened to photons with glass. But in our experience there are no "fractions" of photon or electron: these particles are not made of plasticine and you cannot detach pieces of them at will. So the final result must always be only one, that is reflection or crossing. If the calculations tell us that the first eventuality occurs in 20 percent of the cases, this means that all the electron or photon is reflected with 20 percent probability. We know this thanks to Schrodinger's equation, which gives us the result in terms of Y2. It was with the help of analogous experiments that physicists abandoned the original Schrödinger's interpretation, that was to say that it provided "plasticine" electrons, i.e. matter waves, to arrive to the probabilistic one, much less intuitive, according to which a certain mathematical function, Y2, provided the probability to find the particles in a certain position at a given instant. If we shoot a thousand electrons against a screen and check with a Geiger counter how many of them pass it, we find maybe that 568 have passed and 432 have been reflected. Which of them was this fate? There is no way to know, neither now nor ever. This is the frustrating reality of quantum physics. All we can do is calculate the probability of the event, Y2.

Science and Spirituality are complimentary.

Light is a form of energy. It can be produced in various ways, transforming electrical energy (as seen for example in a light bulb, or in the redness of toaster resistances) or chemical energy (as in candles and combustion processes in general). The sunlight, a consequence of the high temperatures present on the surface of our star, comes from nuclear fusion processes that take place inside it. And also the radioactive particles produced by a nuclear reactor here on Earth emit a blue light when they enter the water (which ionize, i.e. tear electrons from atoms). It only takes a small amount of energy put into any substance to heat it. At small scales, this can be felt as a moderate temperature increase (as well knows also those who dabble with DIY on weekends, nails get warm after a series of hammering, or if they are torn from the wood with pliers). If we supply enough energy to a piece of iron, it begins to emit light radiation; initially it is reddish in color, then as the temperature increases we see orange, yellow, green and blue tones appear in order. At the end, if the heat is high enough, the emitted light becomes white, the result of the sum of all colors.

Quantam physics explained.

Let's consider two identical photons (the particles of which the light is made) and shoot them in the direction of a window. There are several alternatives: both of them bounce on the glass, both of them cross it, one bounces and one crosses it. Well, quantum physics is not able to predict how the single photons will behave, whose future is not known even in principle. We can only calculate the probability with which the various alternatives will happen - for example that such a photon will be rejected at 10% and will pass to 90%, but nothing more. Quantum physics may seem vague and inaccurate at this point, but it actually provides the correct procedures (the only correct procedures, to be precise) that allow us to understand how matter works. It is also the only way to understand the atomic world, the structure and behavior of particles, the formation of molecules, the mechanism of radiation (the light we see comes from atoms). Thanks to her we were able, in a second time, to penetrate into the nucleus, to understand how the quarks that form protons and neutrons are bound together, how the Sun gets its gigantic energy, and more. But how is it possible that the physics of Galileo and Newton, so tragically inadequate to describe the atomic motions, is able to predict with few, elegant equations the motions of celestial bodies, phenomena such as eclipses or the return of Halley's comet in 2061 (a Thursday afternoon) and the trajectories of spacecraft?
It is thanks to classical physics that we can design the wings of airplanes, skyscrapers and bridges able to withstand strong winds and earthquakes, or robots able to perform highprecision surgery. Why does everything work so well, if quantum mechanics shows us with great evidence that the world does not work at all as we thought? This happens: when huge amounts of atoms join together to form macroscopic objects, as in the examples we just did (airplanes, bridges and robots), the disturbing and counterintuitive quantum phenomena, with their load of uncertainty, seem to erase each other and bring the phenomena back to the bedrock of the precise predictability of Newtonian physics. The reason why this happens, in money, is of a statistical nature. When we read that the average number of members of American families is equal to 2,637 individuals we are faced with a precise and deterministic data. Too bad however that no family has exactly 2,637 members.
