Swedish plasma physicists refer to researchers and scientists in Sweden who specialize in the study of plasma physics, which is the branch of physics that deals with plasmas—ionized gases composed of charged particles, including ions and electrons. Plasma is often referred to as the fourth state of matter, alongside solid, liquid, and gas.
Bodil Jönsson is a Swedish physicist, author, and speaker, well-known for her work in the fields of time, aging, and the philosophy of time. She has gained recognition for her ability to communicate complex scientific concepts to a general audience and has written several influential books, including "Time is a Created Thing" (original title: "Tid är något vi gör") which explores the nature of time and its impact on our lives.
Gustaf Dalén (1869–1937) was a Swedish engineer and inventor, best known for his work in the field of lighthouse technology and automatic signaling. He made significant contributions to the development of optical devices, particularly the AGA lamp, which improved the efficiency of lighthouses and helped transform maritime navigation. Dalén's inventions included the sun valve, a device that automatically adjusted the intensity of a lighthouse's light based on sunlight.
Torbjörn Sjöstrand is a Swedish individual known primarily for his work in mathematics and related fields. However, there may be limited publicly available information about him, as he is not a widely recognized figure in popular culture or general public discourse.
The divisor function, often denoted as \( d(n) \) or \( \sigma_k(n) \), is a function in number theory that counts or sums the divisors of a positive integer \( n \). 1. **Count of Divisors**: The most common version is \( d(n) \), which counts the total number of positive divisors of \( n \).
Per-Olov Löwdin was a prominent Swedish theoretical physicist and chemist, known for his contributions to quantum chemistry and molecular physics. Born on February 15, 1916, and passing on March 3, 2000, Löwdin is celebrated for his work in the development of mathematical methods to describe atomic and molecular interactions.
Thor Hans Hansson is a prominent figure in the field of computer science, particularly known for his contributions to various areas such as theoretical computer science, programming languages, and formal methods.

Conservation laws are fundamental principles in physics that state certain physical quantities remain constant within a closed system over time. These laws are derived from symmetries in nature and provide crucial insights into the behavior of physical systems. The most well-known conservation laws include: 1. **Conservation of Energy**: The total energy in a closed system remains constant over time. Energy can neither be created nor destroyed but can change forms (e.g., from kinetic to potential energy).

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
