The Goddard problem refers to a classical problem in astrodynamics that involves the optimal control and trajectory optimization of a rocket moving under the influence of gravity. It is named after Robert H. Goddard, an American engineer and physicist who is considered one of the pioneers of rocketry.
Physics in the United Kingdom encompasses the study and application of the fundamental laws of nature, the behavior of matter and energy, and the interactions between various physical systems. The field is explored through various academic institutions, research organizations, and industry, contributing to a wide range of scientific advancements and technological innovations. ### Academic Institutions The UK is home to numerous prestigious universities and research institutions that offer degrees and conduct research in physics.
The Principle of Permanence is a concept that can apply to various fields, including philosophy, science, and law, often referring to the idea that certain states or conditions are enduring and will remain until actively changed.
A free particle is a concept in physics, particularly in classical mechanics and quantum mechanics, referring to a particle that is not subject to any forces other than its own inertial motion. This means that a free particle moves through space without any interaction with other particles or fields and is not influenced by any potential energy. ### In Classical Mechanics: In classical mechanics, a free particle moves in a straight line at a constant speed according to Newton's First Law of Motion.
French mathematical seminars typically refer to academic gatherings or discussion groups focused on various areas of mathematics. These seminars may take place in universities or research institutions across France and involve presentations by researchers, educators, and students on specific mathematical topics, theories, or recent advancements in the field.
Mathematical tools refer to a variety of techniques, methods, and structures that can be used to facilitate mathematical reasoning, problem-solving, and analysis across diverse fields. These tools can range from basic concepts and operations to advanced theories and applications. Here are some categories and examples of mathematical tools: 1. **Basic Operations**: Fundamental arithmetic operations (addition, subtraction, multiplication, division) and properties (associative, commutative, distributive).
The National Society of Black Physicists (NSBP) is an organization dedicated to promoting the participation of Black individuals in the field of physics and related sciences. Founded in 1977, NSBP aims to support the professional development of Black physicists, enhance the visibility of their contributions to the scientific community, and encourage students to pursue careers in physics and STEM (science, technology, engineering, and mathematics) fields.
MinutePhysics is a popular educational YouTube channel created by Henry Reich that specializes in explaining complex physics concepts in a concise and engaging format. The videos typically feature hand-drawn illustrations and animations that help visualize the topics being discussed. Each episode is usually short, lasting around one to two minutes, hence the name "MinutePhysics." The channel covers a wide range of topics in physics, from classical mechanics to modern theories, making complicated ideas more accessible to a general audience.
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!
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.
