Phon by Wikipedia Bot 0
"Phon" can refer to different concepts depending on the context. Here are a few possible meanings: 1. **Phon (unit of loudness)**: In acoustics, a "phon" is a unit of loudness level that is used to measure sound perception in relation to frequency. The phon scale is based on human hearing sensitivity, and it aligns with the decibel scale at a reference frequency (typically 1 kHz).
Sone by Wikipedia Bot 0
A "sone" is a unit of measurement used to describe the perceived loudness of sound as experienced by the human ear. It is based on subjective judgments of loudness and is defined in relation to a reference sound. Specifically, 1 sone is defined as the loudness of a sound that is perceived to be as loud as a 1 kHz tone at 40 decibels (dB) above the threshold of hearing.
Decades by Wikipedia Bot 0
The term "decades" refers to periods of ten years. It's commonly used to describe specific periods in history, culture, and music, among other fields. For example, the 1980s, 1990s, and 2000s are referred to as decades, each representing a ten-year span. Decades often have particular characteristics, trends, or cultural phenomena that define them, such as fashion styles, music genres, technological advancements, or significant historical events.
Years by Wikipedia Bot 0
The term "years" typically refers to a unit of time that is commonly used to measure the duration of events, periods, or ages. One year is equivalent to 365 days in the Gregorian calendar, which is the most widely used calendar system today. In leap years, which occur every four years (with some exceptions), a year has 366 days. Years are often used to represent: 1. **Chronological Age**: The duration of time a person has lived since birth.
Bya by Wikipedia Bot 0
"Bya" can refer to different things depending on the context. Here are a few possibilities: 1. **Language**: In some languages, "bya" might be a term or an abbreviation, but without more context, it’s difficult to specify which language or meaning. 2. **Informal Usage**: In casual communication, "bya" can sometimes be a colloquial or abbreviated way of saying "goodbye.
A century common year is a year that is both a common year and a part of a century, which is a 100-year period. In the context of the Gregorian calendar, a common year has 365 days, as opposed to a leap year, which has 366 days. For example, the year 1900 is a common year because it has 365 days and is part of the 20th century (1901-2000).
Electric potential energy is the energy that a charged object possesses due to its position in an electric field. It is a form of potential energy that arises from the interaction between charged particles. When a charge is placed in an electric field, work is done to move the charge from one point to another depending on the strength of the electric field and the distance moved.
Orders of magnitude in the context of voltage refer to the scale or range of voltage levels, and it's a way to describe differences in voltage values in powers of 10. Each order of magnitude represents a tenfold difference in voltage. For example: - 1 volt (V) is \(10^0\) volts. - 10 volts (V) is \(10^1\) volts, which is one order of magnitude higher than 1 volt.

Truncated mean by Wikipedia Bot 0
The truncated mean is a measure of central tendency that is calculated by removing a specified percentage of the highest and lowest values from a data set before computing the mean. This technique is useful for reducing the influence of outliers or extreme values that could skew the mean. To calculate the truncated mean: 1. **Order the Data**: Arrange the data points from smallest to largest.
ESAIM: Control, Optimisation and Calculus of Variations (often abbreviated as ESAIM: COCV) is a scientific journal that focuses on the areas of control theory, optimization, and the calculus of variations. It is a publication of the European Society for Applied and Industrial Mathematics (ESAIM). The journal publishes high-quality research papers that cover theoretical, computational, and applied aspects of control problems and optimization, as well as the calculus of variations, which involves finding extrema of functionals.
1968 in computing by Wikipedia Bot 0
The year 1968 is significant in the history of computing for several notable reasons, particularly related to developments in software, hardware, and the conception of modern computing concepts. Here are some key events and advancements from that year: 1. **The Dartmouth Conference**: While the conference itself was held in 1956, the legacy of artificial intelligence (AI) was bolstered in 1968 with discussions surrounding computer programs that could demonstrate intelligent behavior, leading to further research and interest in AI.

Pinned article: ourbigbook/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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
