Atom (time) refers to a timekeeping system that is based on the vibrations of atoms, specifically using atomic clocks. Atomic clocks are extremely precise timekeeping devices that measure time based on the oscillations of atoms, typically cesium or rubidium. The most commonly known standard for atomic time is based on the vibrations of cesium atoms.
Discrete-time proportional hazards is a statistical modeling approach used in survival analysis, which deals with time-to-event data. This approach is particularly useful when the time until an event occurs (like failure, death, or another outcome) is recorded at discrete time intervals rather than continuously. ### Key Features: 1. **Discrete Time**: In this model, time is divided into discrete intervals (e.g.
A calendar year is a period of one year that is based on the Gregorian calendar, which is the most widely used civil calendar today. It consists of 12 months, totaling 365 days in a standard year and 366 days in a leap year. The calendar year starts on January 1 and ends on December 31. In different contexts, the term "calendar year" can have specific implications: 1. **Fiscal Year vs.

Pamela J. Bjorkman is an American immunologist and a professor known for her research in the fields of immunology and structural biology. She is particularly recognized for her work on the structure and function of proteins involved in immune responses, including major histocompatibility complex (MHC) proteins and their interactions with T cell receptors. Her research has significant implications for understanding how the immune system recognizes pathogens and for designing vaccines and immunotherapies.
Stigler's Law of Eponymy is a principle in the philosophy of science, named after the statistician Stephen Stigler. It states that no scientific discovery is named after its original discoverer. Instead, discoveries are often attributed to individuals who were not the first to make them, or who popularized the findings, rather than those who first conceived of them.
Strategic voting refers to the practice of casting a vote not solely based on a voter's genuine preferences, but rather to achieve a more favorable outcome in an election. Voters may choose to support a candidate that is not their first choice to prevent an undesirable candidate from winning. This behavior often arises in electoral systems where multiple candidates compete, and it is particularly relevant in systems that do not use a simple plurality rule, such as ranked choice voting or systems with runoff elections.
Super-resolution imaging refers to a set of techniques used to enhance the resolution of an imaging system beyond the traditional limits imposed by diffraction or the physics of light. The goal is to produce images with finer detail and clarity, allowing for structures or features that would typically be indistinguishable at lower resolutions to become visible.

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.
