Transistors.

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals controls the current through another pair of terminals. Since…

China Launches final satellite to complete GPS- like navigation system.

China has launched the final satellite to complete the Beidou satellite navigation system to rival the US GPS satellite navigation system. The launch took place at the satellite launch center in Xichang, Southwest China on June 23 2020. It was carried by a Long March 3B rocket and was successfully placed 30 minutes later into…

Artificial Intelligence

Artificial Intelligence or machine intelligence is intelligence demonstrated by machines. This means that machines are built and programmed to perform intelligent tasks such as understanding human speech, competing in strategic games, autonomously operating cars, etc which were activities exclusively performed by humans. In recent years artificial intelligence has become even more capable than earlier versions…

SpaceX the company founded by Elon Musk has successfully launches two NASA astronauts into space. The launch took place from NASA’s launch center in Cape Canaveral , Florida yesterday 30th of May 2020. Elon Musk is also the founder of Tesla the company that produces electric vehicles. The crew are expected to dock with the…

Electric Vehicles

An electric vehicle used electric motors or traction motors for propulsion. Electric vehicles have been used since the 19th century when electricity was preferred to the internal combustion engine due to the level of comfort and ease of operation it offered it’s users. However, the internal combustion engine became the dominant mode of propulsion for…

Radar

Radar or Radio Detection and Ranging is a system of detecting objects using radio waves. Radar employs radio waves to determine the range, angle and velocity of objects such as aircraft, missiles, ships, motor vehicles etc. A radar system consist of a transmitter producing electromagnetic waves in radio or microwave domain, a transmitting and receiving…

Integrated Circuits

An integrated circuit or IC, also known as chip or microchip is a set of electronic circuits on one small flat piece of semiconductor material usually silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are many times smaller, faster and less expensive than those constructed…

Semiconductors

A semiconductor is a material whose electrical conductivity value falls between a conductor such as an iron rod and an insulator such as glass. Semiconductors are employed in the manufacture of various kinds of electronic devices such as diodes, transistors and integrated circuits. These devices have found wide applications because of their reliability, compactness, power,…

China Launches Most Powerful Rocket Yet For Deep Space Exploration

China launched it’s most powerful rocket yet on May 5 2020 into orbit carrying it’s next generation space capsule to test it’s ability to carry astronauts and it’s overall performance while in space. The purpose of the launch is to verify the rocket’s workability and it’s reliability to carry astronauts and supplies to a future…

Laser

A laser is a device that emits light through a process of optimal amplification based on the simulated emission of electromagnetic radiation. The term “Laser” comes from the acronym for ” Light Amplification by Simulated Emission of Radiation. Laser differs from other sources of light because it emits light which is coherent. This coherence enables…
