Stöcker has been involved in research related to heavy-ion collisions, which serve to explore the properties of nuclear matter under extreme conditions, such as those present in neutron stars or during the early moments of the universe.
As of my last update in October 2021, there is no widely known figure or concept specifically named "Joachim Luther." It's possible you may be referring to Martin Luther, the German monk and theologian who initiated the Protestant Reformation in the 16th century.
Josef Mattauch was a notable German chemist and physicist, primarily recognized for his contributions to the fields of mass spectrometry and nuclear chemistry. He is closely associated with the development of the Mattauch-Herzog configuration, which is a specific arrangement used in mass spectrometers that allows for the effective separation of ions based on their mass-to-charge ratio. His work has had a lasting impact on analytical chemistry and has facilitated advancements in both basic research and various applications in science and industry.
Peter E. Toschek is a notable figure in the fields of physics and electromagnetism, particularly recognized for his contributions to the understanding of laser technology and optical systems. His work often involves the development of advanced laser technologies, including their applications in various scientific and industrial fields.
Ralph Kronig is best known for his work in the field of physics, particularly in atomic and molecular spectroscopy. He is notably recognized for the development of the "Kronig method," which relates to the analysis of atomic spectra and the interpretation of electron configurations in atoms. His contributions have had a significant impact on our understanding of atomic structure and behavior.
Time-Triggered Architecture (TTA) is a concept used in the design of distributed systems, particularly in safety-critical applications such as automotive, aerospace, and industrial automation. The key principle of TTA is to ensure that the behavior of the system is predictable, deterministic, and synchronized based on time rather than events. Here are some fundamental features of Time-Triggered Architecture: 1. **Time Synchronization**: All components in a distributed system operate based on a global time reference.
The Titan Security Key is a hardware-based security device developed by Google to provide strong two-factor authentication (2FA) for online accounts. It uses the FIDO (Fast Identity Online) standard, which supports both Universal 2nd Factor (U2F) and FIDO2 protocols. These protocols enable secure and passwordless authentication. Key features of the Titan Security Key include: 1. **Strong Authentication**: The key provides an additional layer of security beyond usernames and passwords.
As of October 2021, Phoenix Nuclear Technology is a company that specializes in the development and commercialization of advanced nuclear technologies. Their primary focus is on the design and engineering of systems that can enhance nuclear energy production, improve safety, and reduce waste. The company is known for innovative solutions in the nuclear power sector, including reactor designs and technology aimed at transforming nuclear waste into usable fuel. Phoenix Nuclear Technology often collaborates with research institutions and other entities to advance their technologies and bring them to market.
A Flow Process Chart (FPC) is a graphical representation used to illustrate the steps and flow of a process in a detailed manner. It helps visualize how different elements of a process interact and the sequence in which tasks are performed. Flow process charts are commonly used in various fields such as manufacturing, business process management, project management, and service operations.
Phosphodiesterase (PDE) is a type of enzyme that catalyzes the hydrolysis of phosphodiester bonds in nucleotides, specifically in cyclic nucleotide monophosphates like cyclic AMP (cAMP) and cyclic GMP (cGMP). By breaking these bonds, phosphodiesterases regulate the levels of these second messengers within cells, which are involved in various signaling pathways that control physiological processes such as cell growth, differentiation, and apoptosis.
Tonghae Satellite Launching Ground, also known as the Tonghae Satellite Launching Station, is a space launch facility located in North Korea near the city of Tonghae. It was established in the early 1990s and is primarily used for launching satellites into orbit.

Photoelectrowetting is a phenomenon that combines principles of electrowetting and photonic processes to manipulate the wetting properties of liquids on surfaces using light and electric fields. Electrowetting refers to the change in the wettability of a surface when an electric field is applied, which can either increase or decrease the contact angle of a liquid droplet on that surface.

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.

  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.
