Which hyphen has been named the most expensive hyphen in history?

In 1962, the Americans launched the first spacecraft to study Venus, Mariner 1, which crashed a few minutes after launch. First, the antenna on the device failed, which received a signal from the guidance system from the Earth, after which the on-board computer took control. He, too, could not correct the deviation from the course, since the program loaded into it contained a single error - when transferring instructions to the code for punched cards, one of the equations skipped a dash above the letter, the absence of which radically changed the mathematical meaning of the equation. Journalists soon dubbed this line "the most expensive hyphen in history" (in terms of today, the cost of the lost device is $ 135).

Random interesting fact from the Great Encyclopedia:

How are infrared and ultraviolet radiations, which are invisible to the eye, detected?

In 1800, the English astronomer and optician William Herschel (1738-1822) performed a very simple but interesting experiment, intending to test whether heat, as was then commonly believed, was indeed evenly distributed over the solar spectrum.

Moving the thermometer along the solar spectrum, Herschel discovered that the temperature indicated by it not only increased continuously when moving from the ultraviolet end of the spectrum to the red, but its maximum was generally reached in the region lying beyond the red part of the spectrum, that is, where the eye does not see any light. . Herschel explained this phenomenon by invisible thermal radiation emanating from the Sun and deflected by a prism weaker than red, which is why it was called infrared (below red).

In 1801, the German physicist Johann Wilhelm Ritter (1776-1810) made another discovery "symmetrical" to Herschel's and equally important. He set out to investigate the chemical action of various parts of the light spectrum. To do this, he used silver chloride, the blackening of which under the action of rays was discovered back in 1727 by Johann Heinrich Schulze (1687-1744).

Ritter found that the chemical effect of radiation increases gradually along the spectrum from the red end to the violet and reaches a maximum beyond the violet region - where the eye no longer perceives any light. Thus, a new radiation was found in the spectrum, which is present in sunlight and is refracted by a prism stronger than violet, in connection with which it was called ultraviolet (higher than violet).

Almost simultaneously with Ritter, ultraviolet radiation was discovered by the English scientist William Hyde Wollaston (1766-1828), who conducted similar experiments with a solution of gummigut, which changes its color from yellow to green under the action of light.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Artificial intelligence independently concluded a contract 13.11.2023

UK startup Luminance has unveiled its latest development, an artificial intelligence (AI) called Autopilot, which is based on its own language model. This AI can automatically analyze and make changes to contracts, providing a new level of efficiency in working with legal documentation.

Luminance Autopilot provides an effective tool to streamline the workflow of legal teams, significantly reducing time spent on routine tasks and ensuring more accurate and consistent contract drafting.

The company's chief operating officer, Jaeger Gluckin, notes that the new technology solves the problem of the day-to-day routine tasks of lawyers by allowing artificial intelligence to negotiate and agree on contracts by interacting with other artificial intelligence.

Luminance's Autopilot has undergone extensive legal training and research into a company's business data, providing an advanced level of data processing compared to Lumi's previous chatbot. This tool is designed to act as a legal assistant, providing quick access to different parts of a contract and identifying potential problems.

The software demonstrates high speed, analyzing, changing and formalizing the contract in a few minutes. According to Jaeger, legal teams typically spend about 80% of their time processing routine work. Autopilot allows you to identify inconsistencies in contracts, suggesting more appropriate language and aligning them with corporate policies.

The technology highlights controversial points, marking them in red, and suggests alternative wording in accordance with typical company practices. For example, if a contract's non-disclosure agreement specifies 6 years, which is contrary to Luminance's policy, the AI will automatically adjust the term to the appropriate level.
