Mary Lou Jepsen is a prominent American entrepreneur, engineer, and inventor known for her work in the fields of display technology and neuroscience. She has co-founded and held leadership roles in multiple technology firms, and she is particularly recognized for her work with low-cost, high-resolution display technology, which she developed as part of her involvement with One Laptop per Child (OLPC), where she served as the engineering lead for the OLPC project.
High Frequency Trading by WEED e.V. (2014)
Source. Ciro Santilli once talked to a man who had been working on high-frequency trading for the last six years.
He was quite nice.
Ciro asked him in what way did he feel his job contributed to the benefit of society.
He replied that it didn't contribute at all. It was completely useless. More than that, it so completely useless, that it was even pure. A bit like advanced mathematics, but not even providing beauty for anybody outside of the company, since everything is a closely guarded trade secret, unlike mathematics which is normally published for the vanity recognition.
And so, Ciro was enlightened.
The inaugural that predicted the Josephson effect.
Published on Physics Letters, then a new journal, before they split into Physics Letters A and Physics Letters B. True Genius: The Life and Science of John Bardeen mentions that this choice was made rather than the more prestigious Physical Review Letters because they were not yet so confident about the results.
It is called "AC effect" because when we apply a DC voltage, it produces an alternating current on the device.
By looking at the Josephson equations, we see that a positive constant, then just increases linearly without bound.
Wikipedia mentions that this frequency is , so it is very very high, so we are not able to view individual points of the sine curve separately with our instruments.
Also it is likely not going to be very useful for many practical applications in this mode.
An I-V curve can also be seen at: Figure "Electron microscope image of a Josephson junction its I-V curve".

She is a faculty member at Rice University, where she has contributed significantly to the development of technologies for improving healthcare, particularly in low-resource settings. Her research often focuses on innovative solutions for disease detection and diagnosis, as well as the implementation of medical technologies in underserved communities. Additionally, she has been involved in educational initiatives aimed at enhancing engineering and healthcare education.
Begoña Vila may refer to a person, but as of my last update in October 2021, there are no widely recognized public figures or events specifically associated with that name. It’s possible that she could be a private individual, a professional in a specific field, or a person who has gained prominence after my last update.
Thomas Edison was a pioneering figure in the early days of cinema and is credited with producing some of the first films in history. His studio, the Edison Manufacturing Company, was responsible for a number of short films in the late 1800s and early 1900s. Some notable films produced by Thomas Edison include: 1. **The Kiss** (1896) - This short film features a brief scene of a man and woman kissing, which caused quite a sensation at the time.
Dew-Dew-Dewey Day is a lighthearted and whimsical holiday celebrated on December 7th each year, primarily in the United States. The day is named after the character Dewey from the animated movie "A Bug's Life," and it is associated with fun activities, such as dressing up as bugs or insects, and enjoying bug-themed snacks or games. The observance encourages creativity and playful interactions among families and friends.
The Thomas Edison House is a historical site located in Louisville, Kentucky, that was once the residence of the famous American inventor Thomas Edison during his teenage years. The house itself is significant because it serves as a reminder of Edison's early life before he became one of the world’s most prolific inventors, known for his contributions to electric power, telecommunications, and many other fields. The home has been preserved as a museum, showcasing artifacts and exhibits related to Edison’s life and work.
The S1B reactor is a type of research reactor that was developed by the United States. It was primarily used for training naval personnel, conducting experiments, and testing nuclear propulsion technologies. The "S1B" designation indicates that it is part of a series of reactors designed for submarine applications, specifically related to the nuclear propulsion program of the U.S. Navy.
The S4W reactor is a type of advanced nuclear reactor design that is representative of next-generation small modular reactors (SMRs). Developed by various organizations, these reactors aim to provide a safe, efficient, and sustainable method for generating nuclear power. The S4W designation can refer to specific features or characteristics of the reactor, such as its size (small modular reactor) or specific design innovations.
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.Figure 1. Screenshot of the "Derivative" topic page.
