Technical questions

ICQ was the first stand-alone instant messenger (IM) originally developed by the Israeli company Mirabilis in 1996. The name ICQ derives from the English phrase "I Seek You". The technology Mirabilis developed for ICQ was distributed free of charge. The technology's success encouraged AOL to acquire Mirabilis on June 8, 1998 . At its peak around 2001, ICQ had more than 100 million accounts registered.

The James Webb Space Telescope is a space telescope that will be the successor to the Hubble Space Telescope.The JWST will provide greatly improved resolution and sensitivity over the Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology. The JWST's primary mirror is composed of 18 hexagonal mirror segments made of gold-coated beryllium. These combine to create a 6.5-meter (21 ft 4 in) diameter mirror that is much larger than the Hubble's 2.4-meter (7 ft 10 in) mirror.

Myron Krueger is an American computer artist who developed early interactive works. He is also considered to be one of the first generation virtual reality and augmented reality researchers. Krueger went on to develop Metaplay, an integration of visuals, sounds, and responsive techniques into a single framework. In 1971, his "Psychic space" used a sensory floor to perceive the participants' movements around the environment.

On May 15, 1718, Englishman James Puckle patented his machine gun, the world's first! You may have thought the Gatling gun or the Maxim machine gun was the first machine gun, but depending on how you define “machine gun” James Puckle, Esq. (yes, he was a lawyer) got there first.

Norbert Wiener is considered the originator of cybernetics, a formalization of the notion of feedback, with implications for engineering, systems control, computer science, biology, neuroscience, philosophy, and the organization of society. Wiener is credited as being one of the first to theorize that all intelligent behavior was the result of feedback mechanisms, that could possibly be simulated by machines.

The information sent over phone and cable lines are analog waves. So your modem takes the analog waves, changes it to digital and delivers it to your computer. In other words, your modem will connect you to the internet so that you can watch videos, upload videos, check emails, play on Facebook and anything else that you’d like to do online.

The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The equation was written in 1961 by Frank Drake, not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the search for extraterrestrial intelligence (SETI). The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life.

Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe3C. By weight, it is 6.67% carbon and 93.3% iron. It has an orthorhombic crystal structure.

The Bessemer bulb is a cylindrical refractory vessel used to make steel from pig iron. The process is named after its developer Henry Bessemer, who published it in England after the mid-19th century. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.

A supercavitating torpedo is a torpedo using the effect of supercavitation to create a bubble around the torpedo to move at high velocity under water; up to 370 km / h. The disadvantage of such torpedoes is its exceptionally loud work and difficult maneuvering. Current applications of cavitation effects are mainly limited to projectiles or fast supercavitating torpedoes, and some propellers, but in principle the technique could be extended to include entire vehicles.
