The strong CP problem is sometimes regarded as an unsolved problem in physics, and has been referred to as "the most underrated puzzle in all of physics." [1] [2] There are several proposed solutions to solve the strong CP problem. The most well-known is Peccei–Quinn theory, [3] involving new pseudoscalar particles called axions.

The heavily computational AP Physics B course served as the College Board's algebra-based offering for four decades. As part of the College Board's redesign of science courses, AP Physics B was discontinued; therefore, AP Physics 1 and 2 were created with guidance from the National Research Council and the National Science Foundation. [2]
Meanwhile, AP Physics 2 covered the other content areas. In 2020, the sound, waves, and electricity topics were removed from AP Physics 1 and moved to AP Physics 2. In 2024, the unit covering fluids was moved from AP Physics 2 to AP Physics 1, making space in the AP Physics 2 curriculum for more detail on waves and modern physics. [2] [7]
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.
A 1966 revision of the first edition of Part I changed the title of the textbook to Physics. [1] It is widely used in colleges as part of the undergraduate physics courses, and has been well known to science and engineering students for decades as "the gold standard" of freshman-level physics texts.
A panelist who appeared before the UK’s House of Commons Science and Technology Committee to discuss the link between diversity in STEM and social mobility on April 27 said girls may avoid ...
At a temperature of 4.2 K and a thickness of cobalt layers of 1.5 nm, increasing the thickness of copper layers d Cu from 1 to 10 nm decreased δ H from 80 to 10% in the CIP geometry. Meanwhile, in the CPP geometry the maximum of δ H (125%) was observed for d Cu = 2.5 nm, and increasing d Cu to 10 nm reduced δ H to 60% in an oscillating manner.
