Forty years of Efimov physics: How a bizarre prediction turned into a hot topic


It was Einstein who later proposed that it is the electromagnetic radiation itself that is quantized into photons. Here is professor John Baez advice on how to learn physics and mathematics. He mentions the books you should read, and they are conveniently listed according to increasing levels of difficulty. One of the peculiar observations that has emerged from the study of the quantum realm is non-locality.

Solution for Atomic Clock Puzzle

As the name quantum mechanics implies, certain physical quantities such as angular momentum can change only in discrete amounts, and not in a continuous (cf. analog) way. Physics education or physics teaching refers to the education methods currently used to teach physics. The occupation is called physics educator or physics teacher. Physics education research refers to an area of pedagogical research that seeks to improve those methods. Historically, physics has been taught at the high school and college level primarily by the lecture method together with laboratory exercises aimed at verifying concepts taught in the lectures. These concepts are better understood when lectures are accompanied with demonstration, hand-on experiments, and questions that require students to ponder what will happen in an experiment and why.

Of course, we don’t think of these other fields as part of physics. When we investigate something scientifically, we look for patterns at the scale that is most appropriate. Even when looking at the behavior of a liquid, we look in general at the properties of the fluid as a whole through fluid dynamics, rather than paying particular attention to the behavior of the individual particles.

How to Get a Ph.D. in Physics

But what we ultimately want from a theory of consciousness is an explanation of why brain activity—of whatever form—is correlated with consciousness in the first place. Because consciousness is not an observable phenomenon, the “why” question is not one we can make progress on with experiments. Physics is based on a number of central theories from which everything else develops. It is therefore very likely that the problems you will have to solve in the exam will be based on these core concepts or a variation of these. Consequently, instead of trying to memorize complex problems, it is advisable to assimilate the basic concepts and theories which will help you understand the underlying principles and the connection between different subjects. Majoring in physics and obtaining a doctorate in the field is no small feat, and employers from all fields recognize that. Physics is incredibly quantitative and numerical; thus, you might get a job in fields such as engineering, finance, forensics and even algorithmic trading.

But what about deeper usage of AI/ML in physics beyond using it as an everyday tool? Can they help us solve deep problems of great significance? Could physicists, for example, have used AI/ML to come up with the Bardeen-Cooper-Schrieffer theory of superconductivity in 1950 if they had been available? Can AI/ML revolutionize doing theoretical physics by finding ideas and concepts such as the general theory of relativity or the Schrödinger equation? Most physicists I talk to firmly believe that this would be impossible. I do not know of any mathematician who believes that AI/ML can prove, say, Riemann’s hypothesis or Goldbach’s conjecture.

On these subatomic scales, physics operates in ways that confound our intuitions. When you talk about theoretical physics, you are speaking of the area of physics that is focused on developing these laws and using them to extrapolate into new predictions. These predictions from theoretical physicists then create new questions that experimental physicists then develop experiments to test. In this way, the theoretical and experimental components of physics interact with each other and push each other forward to develop new areas of knowledge. Physics is the scientific study of matter and energy and how they interact with each other.
