An electroluminescent display (EL display) is a type of flat panel display technology that produces light through the process of electroluminescence. In an electroluminescent material, when an electric current is applied, it emits light as a result of the recombination of electrons and holes in a semiconductor material.
Ferroelectricity is a property of certain materials that exhibit a spontaneous electric polarization that can be reoriented by an external electric field. This means that, unlike ordinary dielectric materials that only polarize in response to an applied electric field, ferroelectric materials can maintain a permanent electric polarization even when the external field is removed.
Based on the fact that we don't have a P algorithm for the discrete logarithm of the cyclic group as of 2020, but we do have an efficient algorithm for modular exponentiation. But nor do we have proof that one does not exist! Living on the edge as usual for public-key cryptography.
In the context of electromagnetic phenomena, "Hiss" typically refers to a type of noise or signal often associated with the natural phenomenon of auroras or other similar atmospheric interactions. Specifically, "hiss" can describe a kind of low-frequency radio noise that is detected in the ionosphere, arising from various natural sources including lightning discharges, solar activities, and auroras.
Kirlian photography is a technique that captures the phenomenon of electrical discharges, often referred to as "electrography." This method was developed in the late 1930s by the Russian photographer Semyon Kirlian and his wife Valentina, who accidentally discovered that objects placed on a photographic plate connected to a high-voltage source would produce unique images characterized by glowing, colorful halos or auras around them.
Lightning refers to a natural electrical discharge that occurs during thunderstorms. It is characterized by a bright flash of light, a rapid release of energy, and can occur between clouds, between a cloud and the ground, or within a single cloud. The phenomenon is a result of the buildup of electrical charge within a storm cloud, which occurs due to the movement of water droplets and ice particles. When the difference in electrical charge becomes too great, it results in a sudden discharge of electricity, creating the lightning bolt.
Lightning activity levels are classifications or scales used to describe the frequency and intensity of lightning strikes in a particular area over a specific period. These activity levels can help meteorologists and researchers understand and predict thunderstorms and severe weather. Lightning activity levels can vary based on different factors, including: 1. **Frequency**: The number of lightning strikes within a given area over a defined time frame. 2. **Intensity**: The strength or energy of the lightning, which can affect the damage it may cause.
Abdel Nasser Tawfik may refer to a specific individual, but there isn't widely available public information about a person by that name as of my last update in October 2023. It’s possible that he is a private citizen, a lesser-known figure, or a professional in a specific field not covered in major sources.
Egyptian women physicists have made significant contributions to the field of physics, often overcoming societal challenges and gender barriers in pursuing their careers. Like many women in STEM (Science, Technology, Engineering, and Mathematics) fields, they have worked in various specializations within physics, including theoretical physics, experimental physics, astrophysics, and applied physics. Historically, women in Egypt, as in many parts of the world, faced obstacles in education and professional advancement.
Egyptian nuclear physicists are scientists and researchers from Egypt who specialize in the field of nuclear physics. This branch of physics focuses on understanding atomic nuclei, their constituents, and their interactions. Nuclear physicists in Egypt may engage in various research areas such as nuclear energy, nuclear medicine, radiation physics, and particle physics.
"Mathematics in Ancient Egypt: A Contextual History" is a scholarly work that explores the development and application of mathematical concepts in ancient Egyptian society. This book typically examines the historical, cultural, and practical contexts in which mathematics was used in ancient Egypt, shedding light on how it interacted with various aspects of life, including architecture, astronomy, trade, and daily activities.
The Teller-Ulam design is a foundational concept in nuclear weapon design that describes a configuration for thermonuclear weapons, commonly known as hydrogen bombs. The design was developed in the early 1950s and is named after its principal architects, physicist Edward Teller and mathematician Stanislaw Ulam. ### Historical Context 1. **Early Nuclear Weapons (1940s)**: The first nuclear weapons, developed during World War II under the Manhattan Project, were fission bombs (atomic bombs).
A boosted fission weapon is a type of nuclear weapon that enhances the yield of its fission reaction through the use of a small amount of fusion fuel. In a typical fission bomb, the energy released comes primarily from nuclear fission, which is the splitting of heavy atomic nuclei (such as uranium-235 or plutonium-239) into lighter nuclei, releasing energy in the process.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
