Study Notes

Motion and Force

Ibn Sina (Avicenna) stated that the speed of an object is directly proportional to the force applied to it.
This concept is similar to the rules of velocity and force taught in modern physics classes.

Optics and Vision

Islamic scholars made significant contributions to the field of optics and vision, led by scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi, and Avicenna.
Ibn al-Haytham's Book of Optics (Kitāb al-Manāẓir) presented an alternative to ancient Greek ideas about vision.
He studied the phenomenon of the camera obscura and explained how light enters the eye.
His work influenced thinking across disciplines for over 600 years, including medieval art and European scholars like Robert Grosseteste and Leonardo da Vinci.

Physics and Mathematics

Physics uses mathematics to organize and formulate experimental results, obtaining precise or estimated solutions.
The distinction between physics and mathematics is clear-cut: physics is concerned with descriptions of the real world, while mathematics is concerned with abstract patterns.
Physics statements are synthetic, while mathematical statements are analytic.
Mathematics contains hypotheses, while physics contains theories.

Branches of Physics

Pure physics is a branch of fundamental science that accurately describes systems whose length scales are greater than the atomic scale and whose motions are much slower than the speed of light.
Classical physics was replaced by special relativity, which introduced spacetime and allowed for an accurate description of systems with speeds approaching the speed of light.
Quantum mechanics, introduced by Planck, Schrödinger, and others, allowed for an accurate description of atomic and subatomic scales.
General relativity, introduced by Einstein, allowed for a dynamical, curved spacetime, which can be used to describe highly massive systems and the large-scale structure of the universe.

Relation to Other Fields

Physics is used in chemistry and cosmology.
Mathematics and ontology are used in physics.
Experimental results often defy explanation by existing theories, prompting new theories and experiments.

Theoretical Physics

Theoretical physics has historically taken inspiration from philosophy.
Theorists invoke hypothetical ideas, such as parallel universes and higher dimensions, to solve problems with existing theories.
Experimental physicists design and perform experiments, often working in industry, to develop technologies such as MRI and transistors.

Scope and Aims

Physics involves modeling the natural world with theory, usually quantitative.
Physics covers a wide range of phenomena, from elementary particles to the largest superclusters of galaxies.
Condensed matter physics has a large overlap with chemistry, materials science, nanotechnology, and engineering.

Astrophysics

Astrophysics is the application of the theories and methods of physics to the study of stellar structure, stellar evolution, and cosmology.
Astrophysicists apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
The discovery of radio signals from celestial bodies initiated the science of radio astronomy, which has been expanded by space exploration.
