What did physics discover in 2023?

When we think of discoveries in the field of physics, we usually think of Isaac Newton, who lived in the 17th century, or Albert Einstein, who made his main contributions to physics at the beginning of the last century. However, Physics (like all sciences) is a field of knowledge that can never be completed.

It is always possible to know more and better about the universe, and there are still many aspects of Nature that we cannot explain.

In 2023, Physics has advanced with discoveries in a wide variety of fields. Remember some of them below.

Electronic circuits and living tissues

Researchers from universities in Sweden, showed that it is possible to produce electronic circuits in living tissue.

By injecting a gel rich in enzymes into the fish, the chemical reaction between the fish’s organic matter and the gel allowed the creation of an electrical circuit; if its application is expanded, it could be of great value in measuring and understanding the functioning of our nervous system. our system and our brain.

The first x-ray of an atom

American researchers Managed to produce first X-ray image of a single atom. Until this year, the smallest scale at which such an image could be obtained was a group of 10 thousand atoms!

With the new device created by scientists, it is possible to identify a single atom and have a better spatial understanding of the position of each atom within the molecules that make up matter. This discovery could improve the production of various industrial materials and even enable the creation of new materials we have not yet imagined.

Developments in clean energy production

We can also say that continued development in energy production from nuclear fusion. This type of energy is, simply put, the same energy created by stars (our Sun, for example, provides us with all its energy through the nuclear fusion that occurs in its core).

The researchers’ idea is to create an environment in which the reaction can be completely controlled and self-sustaining. This type of reaction It produces much more energy than any form we use today, and it will be an extremely clean energy source..

boiling climate

However, at the end of the hottest year on record, it is worth saying that if there is no livable future on our planet, no discovery in any field of knowledge will have any value in the future. It is now a scientific fact that we are causing the climate changes we are experiencing.

Despite the efforts of some segments of society to deny this phenomenon (for various political reasons), it is a scientific consensus that global warming is caused by humans! Moreover 97% of scientific articles published on this subject agree that humans are responsible for increasing the temperature of the planet. This causes the extreme weather events we have seen this year and in recent years.

Many flaws in method and analysis can easily be found in the very few articles that attempt to deny this fact. This could be another text saying that we must completely change our consumption habits to make it possible for us to survive on the only planet we have.

However, so that these are not just words that herald something inevitable, we need to understand the seriousness of what scientists say as soon as possible. Individual efforts such as recycling and saving resources are laudable but too small to really cause a change in this scenario.

We need a complete change in our model of existence. The current society, which focuses only on consumption, has shown us that the result of this is to make the planet we live in increasingly uninhabitable.

Finally, it is necessary to separate this not from politics (which is impossible), but from the political polarization we are in, so that in many years to come, we can celebrate the continuous progress in human knowledge as a reason for hope. .
