Particle

 Particle

a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.

 

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. ... We now know that atoms are made up of three particles: protons, neutrons and electrons. which are composed of even smaller particles, such as quarks.

 

Elementary particles

 

Fermions, Bosons, Hypothetical particles, Hadrons, Atomic nuclei, Atoms, Molecules.

 

All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. ... We call the particle formed when more than one atom is chemically joined a molecule. If the atoms are the same, then it is a molecule of an element. If the atoms are different, then it is a molecule of a compound.

Radiology is the medical discipline that uses medical imaging to diagnose and treat diseases within the bodies of animals, including humans. Radiologists are medical doctors that specialize in diagnosing and treating injuries and diseases using medical imaging (radiology) procedures (exams/tests) such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET) and ultrasound. a radiologist completes about 13 years of training after high school. In addition to this training, there are two exams to successfully take to become certified by the American Board of Radiology. Some subspecialties of radiology must be chosen during the residency period. Becoming a radiologist can be a very rewarding career. A day in the life of a radiologist may include all of the tasks above, which could be specialized into a specific area of radiology. If you're considering entering this career field, it may be a good idea to understand the tasks of the job first. The required education for a radiologist includes a four-year college degree, medical or osteopathic school and at least four years of residency training. In addition, all radiologists must fulfill the examination requirements for state licensing. Essential skills Attention to detail. Ability to work as an individual and as part of a medical team of specialists. Excellent communication skills. Able to work well in stressful conditions. Critical thinking. Extensive knowledge of and an aptitude for the medical profession.

Magnetism

 Magnetism   is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.   There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism. Diamagnetism arises from the orbiting electrons surrounding each atomic nucleus.   Magnets don't need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves. One class of magnets, called electromagnets, does need electricity to work.   Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets their ability to attr

 Quantum_mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.   science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.   counter-intuitive phenomenon predicted by quantum mechanics is quantum tunnelling: a particle that goes up against a potential barrier can cross it, even if its kinetic energy is smaller than the maximum of the potential.[7] In classical mechanics this particle would be trapped. Quantum tunnelling has several important consequences, enabling radioactive decay, nuclear fusion in stars, and applicat
