Difference between geocentric and heliocentric world design

  In the III century BC, Aristarchus of Samos had concluded that the Earth and other planets orbit around the Sun. He also guessed about the rotation of the Earth around its own axis. However, it took a millennium and … Continue reading →

Maxwell's demon restores order in the container with a gas

On the mind demons… To put things in order, as is well known, you need to do some work. In thermodynamics, this (second) law is expressed in the fact that the disorder of molecule motion in a container with gas, … Continue reading →

Whether there is the use of unsuccessful experiments?

Neutrinos are produced in the atmosphere and are registered in detectors

You never know where you find neutrinos and where you lose In the seventies, experiments were carried out to study the weak interaction in the CERN Big European Bubble Chamber (BEBC). The results of measurement of the interaction parameter, called … Continue reading →

How did they register rare events previously?

On the photographs from a bubble chamber paths of elementary particles are visible

Looking through thousands of photos using own eyes, no computers By the end of 1972, in the bubble chamber experiment Gargamelle, for the first time it was recorded an event of interaction of a muon neutrino with an electron, in … Continue reading →

How was the natural radioactivity of minerals discovered?

Minerals' fluorescence is a result of the transition of an electron in an atom to a lower shell

On the particles flying out of radioactive minerals time to time In 1895, a study of cathode rays led Wilhelm Roentgen to the discovery of X-radiation called by his name later on. At a meeting of the Parisian Academy, Henri … Continue reading →

How was the idea of the existence of antiparticles born?

Posted on August 25, 2014 by admin
The positron is the antiparticle of the electron

Following the predictions of his own theoretical formulae The Dirac equation for electrons has a solution not only with positive but also with negative energy. There were attempts to interpret the latter as protons, but those had been quickly discarded … Continue reading →

Why did they use to say “we are in aether”?

Posted on August 25, 2014 by admin
Hypothetical aether found its place in the World Wide Web -- the Internet

On the difference of radio waves from the sound vibrations in the air Light and sound — that is what from time immemorial people imagined like something flying or self-spreading. Following the ancient scholars, in the Renaissance they believed that … Continue reading →

How did they imagine atoms 100 years ago?

Posted on August 25, 2014 by admin
Electrons in an atom were thought to be like raisins in a pudding

On electron orbiting far from the nucleus of an atom The foundation of modern physics of elementary particles was actually laid by Ernest Rutherford, who was one of the disciples of J.J. Thomson. By 1911, on the basis of experiments … Continue reading →

Who has guessed the first that light propagates in portions?

Posted on August 25, 2014 by admin
The electrons are knocked out of the electron shells of atoms with photons

On the emission of quanta of light waves — photons In 1905, Albert Einstein proposed a far-reaching generalization of Planck’s hypothesis of discrete radiation and successfully applied it to explain the properties of the photoelectric effect. Initially, these Einstein’s views … Continue reading →

Who was the first to speak about the relationship of mass and energy?

Posted on August 25, 2014 by admin
The energy obtained from the rest mass of matter

About gradual separation from the usual concepts for the future In 1881, the founder of atomic physics J.J. Thomson noticed that the inertial mass of а charged particle should increase as it moves, and introduced the concept of electromagnetic mass … Continue reading →

How easy was the quantum mechanics caught?

Posted on August 25, 2014 by admin
Quantum mechanics has brought probability instead of the certainty

About elusive location of elementary particles After creating the Schrodinger formalism of wave mechanics, there were a problem of the physical interpretation of the theory, then the belief has been gradually formed that formalism gives just probability of finding a … Continue reading →

How did they imagine nuclei of atoms before the discovery of neutrons?

Posted on August 25, 2014 by admin
The core is surrounded by the electron shell

About the close proximity of neutrons and protons After the discovery of protons, it has been suggested that they make up atomic nuclei. However, this assumption proved untenable, since the ratio of a nuclear charge to its mass does not … Continue reading →

How did the inequality of matter and antimatter become known?

Posted on August 25, 2014 by admin
Matter begins to annihilate with antimatter

About dull belief in the symmetry of interactions Almost immediately after the discovery of the left-right (mirror) symmetry breaking in the weak interactions, it has been also experimentally proven the violation of the charge symmetry, i.e., non-invariance under replacement of … Continue reading →

How have they guessed that the weak interaction distinguish left and right?

Posted on August 25, 2014 by admin
Violating the left-right symmetry in the weak interaction

How the understanding of asymmetry of the weak interaction was coming Following pions, in 1947 positively charged kaons were discovered, which decay into either two or three pions. These decays are relatively slow as occur due to the weak interaction. … Continue reading →

Posted on August 25, 2014 by admin
Pions were considered to be a carrier of the strong interaction

How they hoped that pions are carriers of the strong interaction… For the first three decades of the XX century, the idea had been formed that interaction between electrically charged particles is due to the exchange of quanta of the … Continue reading →
