Waymo
Waymo LLC, formerly known as the Google Self-Driving Car Project, is an American autonomous driving technology company headquartered in Mountain View, California. It is a subsidiary of Google's parent company (Alphabet Inc., Alphabet Inc). The company traces its origins to the Stanford Racing Team, which Stanley (vehicle), competed in the 2005 and 2007 Defense Advanced Research Projects Agency (DARPA) DARPA Grand Challenge, Grand Challenges. Google's development of self-driving technology began in January 2009, led by Sebastian Thrun, the former director of the Stanford Artificial Intelligence Laboratory (SAIL), and Anthony Levandowski, founder of 510 Systems and Anthony's Robots. After almost two years of road testing, the project was revealed in October 2010. In fall 2015, Google provided "the world's first fully driverless ride on public roads". In December 2016, the project was renamed Waymo and spun out of Google as part of Alphabet. In October 2020, Waymo became the fir ...

Timeline Of Computing 2020–29
A timeline is a list of events displayed in chronological order. It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. This timescale is dependent on the events in the timeline. A timeline of evolution can be over millions of years, whereas a timeline for the day of the September 11 attacks can take place over minutes, and that of an explosion over milliseconds. While many timelines use a linear timescale—especially where very large or small timespans are relevant -- logarithmic timelines entail a logarithmic scale of time; some "hurry up and wait" chronologies are depicted with zoom lens metaphors. More usually, "timeline" refers merely to a data set which could be displayed as described above. For example, this meaning is used in the ...

United Press International
United Press International (UPI) is an American international news agency whose newswires, photo, news film, and audio services provided news material to thousands of newspapers, magazines, radio and television stations for most of the 20th century until its eventual decline beginning in the early 1980s. At its peak, it had more than 6,000 media subscribers. Since the first of several sales and staff cutbacks in 1982, and the 1999 sale of its broadcast client list to its main U.S. rival, the Associated Press, UPI has concentrated on smaller information-market niches. History Formally named United Press Associations for incorporation and legal purposes but publicly known and identified as United Press or UP, the news agency was created by the 1907 uniting of three smaller news syndicates by the Midwest newspaper publisher E. W. Scripps. It was headed by Hugh Baillie (1890–1966) from 1935 to 1955. At the time of his retirement, UP had 2,900 clients in the United States, and 1, ...

Large Hadron Collider
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the CERN, European Organization for Nuclear Research (CERN) between 1998 and 2008, in collaboration with over 10,000 scientists, and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel in circumference and as deep as beneath the France–Switzerland border near Geneva. The first collisions were achieved in 2010 at an energy of 3.5 tera-electronvolts (TeV) per beam, about four times the previous world record. The discovery of the Higgs boson at the LHC was announced in 2012. Between 2013 and 2015, the LHC was shut down and upgraded; after those upgrades it reached 6.5 TeV per beam (13.0 TeV total collision energy). At the end of 2018, it was shut down for maintenance and further upgrades, and reopened over three years later in April 2022. The collider has four crossing points where the accelerated particles ...

Electron
The electron (, or in nuclear reactions) is a subatomic particle with a negative one elementary charge, elementary electric charge. It is a fundamental particle that comprises the ordinary matter that makes up the universe, along with up quark, up and down quark, down quarks. Electrons are extremely lightweight particles that orbit the positively charged atomic nucleus, nucleus of atoms. Their negative charge is balanced by the positive charge of protons in the nucleus, giving atoms their overall electric charge#Charge neutrality, neutral charge. Ordinary matter is composed of atoms, each consisting of a positively charged nucleus surrounded by a number of orbiting electrons equal to the number of protons. The configuration and energy levels of these orbiting electrons determine the chemical properties of an atom. Electrons are bound to the nucleus to different degrees. The outermost or valence electron, valence electrons are the least tightly bound and are responsible for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legal Tender
Legal tender is a form of money that Standard of deferred payment, courts of law are required to recognize as satisfactory payment in court for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which, when offered ("tendered") in payment of a debt, extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt. It is generally only mandatory to recognize the payment of legal tender in the discharge of a monetary debt from a debtor to a creditor. Sellers offering to enter into contractual relationship, such as a contract for the sale of goods, do not need to accept legal tender and may instead contractually require payment using electronic methods, foreign currencies or any other legally recognized object of value. Coins and banknotes are usually defined as legal tender in many countries, but personal cheque, checks, credit c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitcoin
Bitcoin (abbreviation: BTC; Currency symbol, sign: ₿) is the first Decentralized application, decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source software, open-source implementation. In 2021, Bitcoin in El Salvador, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by some scholars as an economic bubble. As bitcoin is pseudonymous, Cryptocurrency and crime, its use by criminals has attracted the attention of regulators, leading to Legality of cryptocurrency by country or territory, its ban by several countries . Bitcoin works through the collaboration of computers, each of which acts as a Node (networking), node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptocurrency
A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungible blockchain tokens that have been created, cryptocurrencies are not considered to be currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as commodities, securities, and currencies. Cryptocurrencies are generally viewed as a distinct asset class in practice. The first cryptocu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
