It became one of the most important languages for artificial intelligence due to its unique features, such as symbolic expression processing. 2. **IBM 7030 (Stretch)**: The IBM 7030, often referred to as "Stretch," was one of the first supercomputers.
The 1960s saw the creation of several significant programming languages that influenced the development of software engineering and computer science. Here are some of the notable programming languages from that decade: 1. **ALGOL (Algorithmic Language)** - Although ALGOL was first introduced in the late 1950s, ALGOL 60, a revised version, was developed and widely adopted in the early 1960s. It introduced many concepts that influenced later programming languages, including structured programming.
In computing, "1970" is often associated with the epoch time, commonly known as Unix time or POSIX time. This is a system for tracking time in many computing systems, where the epoch is defined as 00:00:00 Coordinated Universal Time (UTC) on January 1, 1970. Unix time counts the number of seconds that have elapsed since this epoch, not counting leap seconds.
In computing, "1984" is often associated with several key events and developments in the tech industry, but most notably, it refers to a significant moment in the history of personal computing—the launch of the Apple Macintosh. The Apple Macintosh was introduced in 1984 with a memorable television commercial directed by Ridley Scott that aired during the Super Bowl.
The term "Ultracomputer" can refer to various advanced computing concepts depending on the context in which it is used. However, it is not a well-defined or widely recognized term in computer science or technology literature. 1. **High-Performance Computing**: In some contexts, "Ultracomputer" may refer to supercomputers or systems that utilize cutting-edge technology for high-performance computing tasks, often involving parallel processing, massive data handling, and advanced networking capabilities.
The year 1993 was significant in the computing world for several reasons, marking important developments in technology, software, and the internet. Here are some key highlights from that year: 1. **Web Browser Development**: The first popular web browser, the Mosaic web browser, was released in 1993. It played a crucial role in popularizing the World Wide Web, making it more accessible to the general public and leading to the internet boom in the following years.
Ivan Puluj was a notable Ukrainian physicist, electrical engineer, and inventor born on January 2, 1845, in the Austrian Empire (now Ukraine) and died on January 31, 1918. He is best known for his pioneering work in the field of X-ray technology.
A memory card is a compact, portable storage device used to store digital data. They are often used in devices like cameras, smartphones, tablets, and gaming consoles for storing photos, videos, music, documents, and other types of data. Memory cards typically use flash memory technology, which allows for quick data access and durability since they have no moving parts.
William Spottiswoode (1825–1883) was a notable British mathematician, astronomer, and physicist known for his work in various scientific fields, particularly in optics and astronomy. He made significant contributions to mathematical physics and was involved in the development of new instruments for astronomical observations. Spottiswoode was also an active member of scientific societies and served as the President of the Royal Society from 1878 until his death in 1883.
August Krönig (1800–1873) was a German physicist known for his work in the fields of optics and the study of light. Although specific details about his contributions may not be as widely recognized as those of some other scientists, he is notable for his studies related to polarization and the physical properties of light. One of his recognized contributions is the "Krönig's law," which pertains to how certain optical phenomena relate to physical properties.
John Joseph Montgomery (1858–1911) was an American inventor and aviation pioneer, best known for his pioneering work in heavier-than-air flight. He is often credited with conducting some of the earliest successful manned flights in powered aircraft. Montgomery made significant contributions to the field of aviation by experimenting with gliders and later developing powered aircraft. He is particularly famous for his work on the "Montgomery Glide," a heavier-than-air flying machine that he demonstrated in 1884.
Alois Handl could refer to an individual or a specific term, but as of my last knowledge update in October 2021, there isn't any notable information widely recognized under that name.

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.
