One thing to note is that Jimmy was a finance worker before starting wikipdia, e.g. he had capital to hire Larry Sanger.

Maybe that's the way to go about it, make money first, and later on change the world.

Starting just after the beginning of the Internet can't hurt either. Though tooling must have been insane back then.

Some courses at least allow you to see material for free, e.g.: www.coursera.org/learn/quantum-optics-single-photon/lecture/UYjLu/1-1-canonical-quantization. Lots of video focus as usual for MOOCs.

Some are paywalled: www.coursera.org/learn/theory-of-angular-momentum?specialization=quantum-mechanics-for-engineers

It is extremely hard to find the course materials without enrolling, even if enrolling for free! By trying to make money, they make their website shit.

The comment section does have a lot of activity: www.coursera.org/learn/statistical-mechanics/discussions/weeks/2! Nice. And works like a proper issue tracker. But it is also very hidden.

Ciro Santilli dislikes the fact that they take themselves too seriously. Ciro prefers the jokes and tech approach.

In astronomy, "concepts" refer to the fundamental ideas and principles that help us understand the universe and its various phenomena. Here are some key concepts in astronomy: 1. **Celestial Bodies**: This includes stars, planets, moons, asteroids, comets, galaxies, nebulae, and black holes. Each has distinct characteristics and behaviors. 2. **Orbits**: The motion of celestial bodies as they travel in elliptical paths around larger bodies due to gravitational forces.

Mathematical notation refers to a standardized set of symbols and conventions used to represent mathematical concepts, operations, relationships, and structures. The purpose of such notation is to allow mathematicians and students to communicate ideas clearly and concisely. Here are some key aspects of mathematical notation: 1. **Symbols**: Mathematical notation includes a variety of symbols that represent numbers, operations, relations, functions, and other elements.

Ancient Greek physicists, often referred to as early natural philosophers, were thinkers and scholars in ancient Greece who sought to understand the nature of the physical world. They laid the foundations for various fields of study, including physics, astronomy, and cosmology, through a combination of observation, reasoning, and speculation. Some of the most notable figures include: 1. **Thales of Miletus (c.

Gravitational contact terms refer to specific kinds of contributions that arise in the context of gravitational interactions, particularly when analyzing certain physical processes in quantum gravity or effective field theories. These contact terms typically describe interactions that occur at the same point in space and time, effectively leading to divergences that need to be handled in calculations of scattering amplitudes, correlation functions, or other physical observables.

Fields are a fundamental concept in abstract algebra, a branch of mathematics that studies algebraic structures. A field is a set equipped with two operations: addition and multiplication, satisfying certain properties. Here are the key properties that define a field: 1. **Closure**: For any two elements \(a\) and \(b\) in the field, both \(a + b\) and \(a \cdot b\) are also in the field.

Elementary mathematics refers to the foundational concepts and skills in mathematics that are typically taught at the primary and secondary education levels. It encompasses a variety of topics that form the basis for more advanced mathematical studies. Key areas of elementary mathematics include: 1. **Arithmetic**: Basic operations such as addition, subtraction, multiplication, and division, as well as understanding numbers, fractions, decimals, and percentages.
