Light bulb that never been turned off since 1901. ivermore's Centennial Light Bulb The Centennial Light is the world's longest-lasting light bulb, burning since 1901 , and almost never switched off. Due to its longevity, the bulb has been noted by The Guinness Book of World Records , Ripley's Believe It or Not!, and General Electric.  The Centennial Light was originally a 30-watt(or 60-watt) bulb, but is now very dim, emitting about the same light as a 4-watt nightlight. The hand-blown, carbon-filament common light bulb was manufactured in Shelby, Ohio, by the Shelby Electric Company in the late 1890s and was invented by Adolphe A. Chaillet. The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this technology. It was manufactured in Shelby, Ohio, by the Shelby Electric Company in the late 1890s; many just like it still exist and can be found functioning. According to Zylpha Bernal Beck, the bulb was...

Robot is drawn from an old Church Slavonic word, robota, for “servitude,” “forced labor” or “drudgery.” The word, which also has cognates in German, Russian, Polish and Czech, was a product of the central European system of serfdom by which a tenant’s rent was paid for in forced labor or service. The word robot was coined by artist Josef Čapek, the brother of famed Czechoslovakian author Karel Čapek. As a word, robot is a relative newcomer to the English language. It was the brainchild of a brilliant Czech playwright, novelist and journalist named Karel Čapek (1880-1938) who introduced it in his 1920 hit play, R.U.R., or Rossum’s Universal Robots. The robots in this play were not what we would call robots today, and they weren’t made of steel, plastic, and lines of code. Those robots were manufactured as pseudo-organic components out of a substance that acted like protoplasm in a factory, then “assembled” into humanoids.

Wireless power transfer Inventor and engineer Nikola Tesla, 'the man who invented the 20th century' theorized about wireless electricity back in the 1890s. He even demonstrated the principle by lighting up glass tubes with wireless power transmission. Nikola Tesla wanted to create the way to supply power without stringing wires. He almost accomplished his goal when his experiment led him to creation of the Tesla coil. It was the first system that could wirelessly transmit electricity. Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. Wireless power transfer (WPT) is one of the hottest topics being actively studied, and it is being widely commercialized. In particular, there has been a rapid expansion of WPT in mobile phone chargers, stationary charging electric vehicles (EVs), and dynamic charging EVs, also called road-po...

Satellite A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a natural satellite because it orbits the sun. Likewise, the moon is a natural satellite because it orbits Earth. Usually, the word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space. A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth). On 4 October 1957, the Soviet Union launched the world's first artificial satellite , Sputnik 1. Since then, about 8,900 satellites from more than 40 countries have been launched. According to a 2018 estimate, about 5,000 remained in orbit. Satellites are used for many purposes. Among several other applications, they can be used to make star maps and maps of planetary surfaces, and also take pict...

Modem ( Mo dulator- Dem odulator) A modem is a device that modulates an analog signal to digital information. It also decodes carrier signals to demodulates the transmitted information. It is a hardware component that allows a computer or another device, such as a router or switch, to connect to the Internet. It converts or "modulates" an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize. Similarly, it converts digital data from a computer or other device into an analog signal that can be sent over standard telephone lines. The main aim of the modem is to produce a signal that can be transmitted easily and decoded to reproduce the digital data in its original form. Modems are also used for transmitting analog signals, from Light Emitting Diodes (LED) to radio. A modem is a device that connects your home, usually through a coax cable connection, to your Internet service provider (ISP), like Xfinity. The modem takes sign...

Optical fiber Optical fiber is the technology associated with data transmission using light pulses travelling along with a long fiber which is usually made of plastic or glass. Metal wires are preferred for transmission in optical fiber communication as signals travel with fewer damages. An optical fiber (or fibre in British English) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are of...

Cloud computing Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage. Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change. Cloud computing is a big shift from the traditional way businesses think about IT resources. Cloud computing has been credited with increasing competitivenes...

CHROME OS In September 2008, Pichai oversaw the successful launch of the Chrome web browser, and less than a year later, the web-based Chrome operating system for netbooks and desktop computers. Google announced the project, based on Ubuntu, in July 2009, conceiving it as an operating system in which both applications and user data reside in the cloud: hence Chrome OS primarily runs web applications. The first Chrome OS laptop, known as a Chromebook, arrived in May 2011. Initial Chromebook shipments from Samsung and Acer occurred in July 2011.   Chrome OS has an integrated media player and file manager. It supports Chrome Apps, which resemble native applications, as well as remote access to the desktop. As more Chrome OS machines have entered the market, the operating system is now seldom evaluated apart from the hardware that runs it. A Chromebook (styled as chromebook) is a laptop or tablet running the Linux-based Chrome OS as its operating system. Chromebooks are primarily ...

How does Internet works? What is internet? The Internet is the backbone of the Web, the technical infrastructure that makes the Web possible. At its most basic, the Internet is a large network of computers which communicate all together. When two computers need to communicate, you have to link them, either physically (usually with an Ethernet cable) or wirelessly (for example with WiFi or Bluetooth systems). The internet works by allowing computers to “talk” to one another in order to transfer information. It’s exactly like that with the internet. It begins with the simple idea of a message. The internet as we know it is a complex, interwoven series of these messages; sending and receiving thousands of times per minute, all across the globe. The internet works like a conversation. This conversation has many participants, translators, and multiple messages going back and forth all the time. Over time, it has become very complicated. In fact, it’s so complicated, that there are ...

Google I/O 2021: Google unveils new AI model LaMDA, to aid natural conversations with machines Google on dated 18-May-2021 unveiled its latest language breakthrough, the development of a conversational language model called LaMDA (Language Model for Dialogue Applications). Google discussed the new model during the keynote address at its I/O conference. Google says LaMDA, or Language Model for Dialogue Applications, can engage in a free-flowing way about a seemingly endless number of topics, an ability we think could unlock more natural ways of interacting with technology and entirely new categories of helpful applications Like other recently-developed language models, including BERT and GPT-3, LaMDA is built on Transformer, the neural network architecture that Google Research invented and open-sourced in 2017. However, unlike other language models, Google's LaMDA was trained on dialogue, teaching it how to engage in free-flowing conversations. This training taught LaMDA to ...
