A new study suggests that exist subatomic particles called quarks charm inside the protons.
The cosmic rays are a set of particles with high energy that arrives at Earth’s atmosphere every day, at speeds close to the light.
Researchers may have discovered the tetraneutron, an atomic nucleus with only 4 neutrons. That theoretically shouldn’t exist.
In this third part, are shown the operation principle, advantages and disadvantages, and the applications of fiber laser.
The new BASE measure with high precision didn’t show substantial differences between protons and antiprotons, beyond the electric charge signal.
Semiconductor or diode lasers are the most used nowadays. The operation and materials used in this type of laser are shown in this post.
This is the first post of laser types series. Toady’s subject is the operation of the main gas lasers, which were created in the 1960s.
This is the first of a series of posts related to lasers. This post’s topic is about the principle of laser operation.
2 billion years ago, occurred a nuclear fission in the Oklo uranium deposit, current Gabon, Central Africa. It’s the only natural nuclear reactor discovered so far.
The IceCube Neutrino Observatory, in Antarctica, detected an antimatter particle with highest energy ever registered. This event was predicted in 1960.
