Interference demonstrates the wave-like behavior of electrons

  Electrons are tiny, so a nickel surface should reflect them at various angles since a sample of nickel consists of many randomly oriented small crystals. This is called the diffuse reflection. This is what Davisson and Germer thought in … Continue reading →

How did they imagine the creation of tachyons?

The trajectory of a tachyon, invisible in a bubble chamber

Trying to do without the perception through feelings The searches for a hypothetical tachyon particle were active at the end of the last century. It was expected that when moving through a detector, a charged tachyon would leave no trace … Continue reading →

How to convert a muon into an electron?

A superconducting solenoid for an experiment on the search for neutrinoless conversion of muons into electrons

About the commitment to discover the neutrinoless conversion Following the discovery of neutrino oscillations, experiments on the search for neutrinoless muon-to-electron conversion have started in the United States and Japan. Such a conversion would violate the customary law of conservation … Continue reading →

Can you trust the particle detector?

Precise calibration ensures discoveries

On sharp pricks When using simple measuring instruments such as a micrometer or ammeter, they hope for the accuracy of measurement, indicated on the tool, obtained as a result of its calibration. Detectors, used at the Large Hadron Collider, are … Continue reading →

How to see trajectories of interacting particles?

The bubble chamber photographed the tracks of elementary particles

Leaving a helical track behind In our time, the visualization of tracks and vertices of particle interactions is done by computer processing of electrical signals caused by charged particles flying through so-called wire chambers. In the 80s, these came to … Continue reading →

How to create a neutrino beam?

Magnetic horn, narrowing beam of muon neutrinos

About the countless muon neutrinos flying in a beam… The discovery of partons in nucleons and intermediate bosons involved in weak interactions has been made owing to the fact that at experimenters’ disposal in the 60s, there were high-energy beams … Continue reading →

Does the speed of light depend on the speed of its source?

Posted on August 27, 2014 by admin
Interference fringes of light in the experiment measuring its speed

On the indifference of photons to the velocity of their own source Crucial in this regard was the experiment conducted by Michelson and Morley in 1887 in Cleveland, Ohio. There were observed fringes formed by the interference of light passing … Continue reading →
