The word “algebra” comes from the Arabic word “al-jabr”, which means “reunion of broken parts” or “restoration”. This term was used by the Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī in his 9th-century book “Kitab al-jabr wa al-muqabala”, which introduced methods for solving equations and laid the foundation for modern algebra. The word “algebra” was later translated into Latin and other languages, and gradually expanded to cover a wider range of mathematical topics and concepts.

Richard Feynman on government and scientific truths ✍️

No government has the right to decide on the truth of scientific principles, nor to prescribe in any way the character of the questions investigated. Neither may a government determine the aesthetic value of artistic creations, nor limit the forms of literacy or artistic expression. Nor should it pronounce on the validity of economic, historic, religious, or philosophical doctrines. Instead it has a duty to its citizens to maintain the freedom, to let those citizens contribute to the further adventure and the development of the human race.

Physicist Freeman Dyson was a polymath who had interests and knowledge in many fields, such as topology, number theory, random matrices, quantum electrodynamics, astrophysics, biology, philosophy and theology.

He developed the Dyson series, a perturbative method for solving quantum field theory problems.
He unified the three different formulations of quantum electrodynamics (QED) by Richard Feynman, Julian Schwinger and Shin’ichiro Tomonaga, and showed that they were equivalent.

He also proved the stability of matter, a fundamental result in quantum mechanics that states that matter cannot collapse into a singularity under the influence of the electromagnetic force.

The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them. In this methodological uncertainty, one might suppose that there were any number of possible systems of theoretical physics all equally well justified; and this opinion is no doubt correct, theoretically. But the development of physics has shown that at any given moment, out of all conceivable constructions, a single one has always proved itself decidedly superior to all the rest.
