A new member of the family of subatomic particles can clear up the mystery of the most powerful force in the universe. It is the force that holds the nucleus of every atom, the strong nuclear interaction. The newly observed particle has a complicated name: D * s3 (2860) ˉ. As the protons and neutrons that comprise the nucleus of an atom, D * s3 (2860) ˉ is composed of fundamental units of matter particles called quark.
Scientists have discovered a new particle using an instrument at the Large Hadron Collider (LHC). (A hadron is any particle made of quarks.) LHC is the most powerful particle accelerator in the world. This device is also known as a synchrotron, and is located outside Geneva, Switzerland. A collider accelerates the particles near the speed of light and smashes.
History is full of chemical tragedies. In addition to the atomic bomb, the elements of the periodic table took generations to madness, provoked killings, stripped armies and made whole European region is known for its "idiots." Disasters, weapons and guided diseases for centuries, chemical science. "We have interesting problems to solve. From our humble way, we (chemical) really try to save the planet," says the Swedish chemist Lars Öhrström, researcher at Chalmers University in Gothenburg, Sweden, and member of Pure Chemistry of the International Union and Applied (IUPAC), the world-famous institution for naming new elements and build the official periodic table.
In his second book, The Last Alchemist in Paris (The Last Alchemist Paris, published earlier this year in the United States and no translation in Brazil), Öhrstrom brings together two dozen historical cases in which atoms and molecules are the protagonists. There are stories about nuclear findings, disease cure and scientific puzzles that, through simple explanations and some formulas, the scientist sets out to decipher. The goal is to show that we are made and we are surrounded by these structures. And without knowing how they work, we will always be dominated by them.
