The man who knew everything showed how light should be considered

Until recently, a classic battle between physicists was to determine whether light should be considered a wave phenomenon (formed by waves) or corpuscular (formed by particles. This last position was adopted by scientists such as Isaac Newton or Albert Einstein. However , the controversy was not resolved until a less known scientist took charge of the matter.
We already had the periodic table of the elements: it is time to have that of the molecules
We already had the periodic table of the elements: it is time to have that of the molecules
In order to build a periodic table for molecules with multiple types of symmetries, researchers from the Tokyo Institute of Technology have presented a new approach proposing periodic rules to predict the existence of certain molecules. The new approach is based on an acute observation of the behavior of the valence electrons of atoms that form molecular groups.

A particle accelerator ten times more powerful than LHC? CERN has already submitted
LHC stands for the Large Hadron Collider (in English, Large Hadron Collider), the largest particle accelerator on the planet, located at CERN, in Geneva. Thanks to him, for example, we discovered the Higgs boson. The LHC is truly huge: a ring 27 kilometers underground.

Imitating nature to collect condensed water from the night fog
A new method to collect water from the environment in the desert has been inspired has been inspired by some examples of nature, such as cactus, beetle and desert herbs collect condensed water from the night fog, collecting droplets from the air and filtering them to the roots, providing enough hydration to survive.
You are going to vote to change the definition of "kilogram" to make it more precise
You are going to vote to change the definition of "kilogram" to make it more precise
From November 13 to 16 the new definition of kilogram will be discussed in Versailles, with the purpose of referring to a more stable measurement base and allowing the development of more precise measuring devices. The 60 member countries that make up the General Conference on Weights and Measures will vote to change to a system in which the kilogram will be defined indirectly, through the use of Planck's constant.
The world's largest particle accelerator design is approved
The world's largest particle accelerator design is approved
China plans to build the CEPC (Circular Electron Positron Collider) by 2030. The first step was to obtain approval of the conceptual design of what will be the world's largest particle accelerator. Once you have passed all international exams, that has already happened. CEPC With 100 kilometers of circumference, CEPC will have a budget of 5.

New way of storing information in a single atom is discovered
New way of storing information in a single atom is discovered
A new mechanism for the magnetic storage of information in a single atom has been discovered by researchers at the University of Radboud. His study has been published in Nature Communications. The question that the study leader, Brian Kiraly wanted to clarify, was how can we store information in a single atom and with what stability can we keep that information?
An electronic transition of hydrogen in antimatter is observed for the first time
An electronic transition of hydrogen in antimatter is observed for the first time
For the first time the electronic transition Lyman-alpha, which occurs in hydrogen, in an antihydrogen atom, the counterpart of the antimatter of hydrogen, has been observed by researchers from the University of Swansea working in the physics laboratory of CERN particles.
The coldest temperature in the universe is reached at the International Space Station
The coldest temperature in the universe is reached at the International Space Station
In the field of the International Space Station (ISS) it has been possible to create the coldest point in the universe with a laboratory that has begun to produce clouds of atoms at a temperature just above absolute zero, the lowest temperature that can be obtained due to to the laws of physics, it is the point at which atoms theoretically should stop moving completely (-273.15 degrees Celsius).

The crazy plan to predict the weather with great precision
"Too bad emails are not as accurate as the weather service," Doc Brown said in Back to the Future II when he is able to know exactly when it will stop raining. However, most likely, the postal service ends up being much more accurate than the weather service.
Where has the longest echo in the world been recorded?
Where has the longest echo in the world been recorded?
According to legend, the yodel or Tyrolean song emerged as a means of long-distance communication between pastors, but it is suspected that its origins are Polish. Not a single word is articulated, they are all screams that are often uttered in places where there is an echo, such as lakes, rocky walls, grottos, and so on.

Di-omega: a new type of subatomic particle?
Containing six quarks instead of the usual three, di-omega could be a new exotic particle, as predicted by a study by the HAL QCD Collaboration, formed by scientists from the RIKEN Nishina Center for Accelerator-based Science and RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS).

Using lasers in space, NASA is about to reach the lowest temperature in the universe
NASA is sending a device to the International Space Station (ISS) that will create a point ten billion times colder than the vacuum of space. It's called Cold Atom Laboratory, a chest-sized device aboard the Cygnus rocket of the Orbital ATK, and it will help scientists observe the strange quantum properties of ultra-cold atoms.
