The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
Unanswerable questions may not have solutions, but they sure give our minds one heck of a workout. That's what makes them equally fun and frustrating to ponder. Trying to come up with joke answers ...
Brief Answers to the Big Questions is a popular science book written by physicist Stephen Hawking, and published by Hodder & Stoughton (hardcover) and Bantam Books (paperback) on 16 October 2018. The book examines some of the universe 's greatest mysteries, and promotes the view that science is very important in helping to solve problems on ...
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
Physics Forums is a question and answer Internet forum that allows users to ask, answer and comment on grade-school through graduate-level science questions. In addition, Physics Forums hosts the Insights Blog which is a collaborative blog sourced from verified experts on the community. Authors of scientific papers have used Physics Forums to ...
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...
Maxwell's equations, which unify light, fields, and charge are one of the great milestones of theoretical physics. [ 25 ] : 696–700 The work of many researchers enabled the use of electronics to convert signals into high frequency oscillating currents and, via suitably shaped conductors, electricity permits the transmission and reception of ...
In the more recent editions of the textbook, beginning with the fifth edition, [4] Walker has included "checkpoint" questions. These are conceptual ranking-task questions that help the student before embarking on numerical calculations. The textbook covers most of the basic topics in physics: Mechanics; Waves; Thermodynamics; Electromagnetism ...
