The English Electric DEUCE is a transistorized computer system developed in the early 1960s in the United Kingdom. It was designed by English Electric's Computing Machine Laboratory and aimed to be an advanced computing system suitable for various scientific and industrial applications. The DEUCE was notable for being one of the first computers to utilize transistor technology instead of vacuum tubes, which resulted in improvements in reliability, speed, and power consumption.
The Elliott 803 is a historic computer system that was developed in the early 1960s by the Elliott Automation company in the United Kingdom. It is part of the Elliott series of computers, which were used primarily in scientific and business applications during that time. The Elliott 803 was known for its reliability and ease of use, and it featured capabilities that made it suitable for both commercial computing and academic research.
Elliott 503 refers to a specific case of a technical pattern observed in financial markets, typically related to Elliott Wave Theory. Elliott Wave Theory, developed by Ralph Nelson Elliott in the 1930s, posits that financial markets move in repetitive cycles or waves driven by investor psychology and sentiment. The "503" pattern specifically is part of the broader categorization of Elliott wave patterns, usually designated by a series of numbers representing different wave structures.
Elliott 152 refers to a specific type of object used in the fields of psychology and behavioral research. It is known as the "Elliott 152" test, which assesses cognitive and motor function. The test typically involves various tasks that measure an individual's ability to process information, respond to stimuli, and perform motor activities.
The EMIDEC 1100 is a historical computer that was developed in the United Kingdom during the 1960s. It was one of the early commercial computers designed and built by the EMIDEC Company, which was a subsidiary of Ferranti Ltd. The EMIDEC 1100 was notable for its role in the development of computing technology in the UK. The EMIDEC 1100 was a transistorized computer, which represented a significant advancement over earlier vacuum tube-based systems.
EDSAC 2, or the Electronic Delay Storage Automatic Calculator 2, was an early computer developed in the United Kingdom, specifically at the University of Cambridge. It was an evolution of the original EDSAC, which was one of the first stored-program computers, operational in 1949. EDSAC 2 was introduced in 1958 and featured several enhancements over its predecessor, including improved performance, increased memory capacity, and the ability to handle more complex calculations.
EDSAC, or Electronic Delay Storage Automatic Computer, was one of the earliest computers built at the University of Cambridge in the United Kingdom. It became operational in 1949 and is notable for being one of the first computers to store programs in memory, a key aspect of the von Neumann architecture. The EDSAC was designed by a team led by Maurice Wilkes and was based on the use of mercury delay lines for storage.
Colossus was one of the world's first programmable digital computers, developed during World War II to help break encrypted German messages. It was designed by British engineer Tommy Flowers and his team at Bletchley Park, where critical codebreaking efforts took place. Colossus began operation in 1944 and was specifically used to decrypt the Lorenz cipher, which was employed for high-level military communications by the German military.
The term "Bombe" can refer to several different concepts depending on the context. Here are a few of the most prominent meanings: 1. **Enigma Bombe**: The most notable reference is to the Bombe machine used during World War II to help decipher the German Enigma code.

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.
