Time Warp Edit Distance (TWED) is a metric used to measure the similarity between two time series. It is particularly useful in scenarios where time series data may be misaligned in time, allowing for the evaluation of sequences that may have temporal distortions or varying speeds.
"Virtually" can refer to a few different concepts depending on the context: 1. **Adverbial Meaning**: In general usage, "virtually" means "almost" or "nearly," suggesting that something is true in effect but not in an absolute sense. For example, if someone says "I virtually finished the project," it implies that they are very close to finishing, but not quite there yet.
As of my last knowledge update in October 2023, "Trajectoid" does not refer to a widely recognized concept, term, or specific entity in the public domain. It’s possible that it could be a new product, service, or concept that has emerged after my last update, or it might be less commonly known or specific to a particular niche or industry.

"Lists of problems" can refer to a variety of contexts depending on the subject matter. Here are a few interpretations: 1. **In Problem-Solving and Critical Thinking**: Lists of problems can refer to specific issues that need to be addressed, analyzed, or solved. These might be challenges in various fields such as economics, environmental science, health care, business, or technology.
Mathematics in Germany has a rich tradition and is prominently integrated into both education and research. Germany is known for its significant contributions to various mathematical fields and hosts numerous prestigious universities and research institutions. ### Historical Context Germany has been home to many renowned mathematicians, such as: - **Carl Friedrich Gauss**, known for his contributions to number theory, statistics, and many other areas. - **David Hilbert**, famous for his work on mathematical logic, algebra, and foundations of geometry.
As mentioned in True Genius: The Life and Science of John Bardeen page 224, the idea of symmetry breaking was a major motivation in Josephson's study of the Josephson effect.
- the basis for the most promising 2019 quantum computing implementation: superconducting quantum computer
- Josephson voltage standard: the most practical/precise Volt standard, which motivated the definition of the ampere in the 2019 redefinition of the SI base units
- SQUID devices, which are:
- very precise magnetometer
- the basis for superconducting quantum computers

An experimental lab video for COVID-19 lockdown. Thanks, COVID-19. Presented by a cute and awkward Adam Stewart.
Uses a SQUID device and control system made by STAR Cryoelectronics. We can see Mr. SQUID EB-03 written on the probe and control box, that is their educational product.
As mentioned on the Mr. SQUID specs, it is a high-temperature superconductor, so liquid nitrogen is used.
He then measures the I-V curve on an Agilent Technologies oscilloscope.
Unfortunately, the video doesn't explain very well what is happening behind the scenes, e.g. with a circuit diagram. That is the curse of university laboratory videos: some of them assume that students will have material from other internal sources.
- youtu.be/ql2Yo5LgU8M?t=211 shows the classic voltage oscillations, presumably on a magnetic field sweep, and then he puts a magnet next to the device from outside the Dewar
- youtu.be/ql2Yo5LgU8M?t=253 demonstrates the formation of Shapiro steps. Inserts a Rohde & Schwarz signal generator into the Dewar to vary the flux. The result is not amazing, but they are visible somewhat.
Two parallel Josephson junctions.

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.
