Erna Schneider Hoover
Erna Schneider Hoover (born June 19, 1926) is an American mathematician notable for inventing a computerized telephone switching method which "revolutionized modern communication" according to several reports. It prevented system overloads by monitoring call center traffic and prioritizing tasks on phone switching systems to enable more robust service during peak calling times. At Bell Laboratories where she worked for over 32 years, Hoover was described as an important pioneer for women in the field of computer technology. Early life Erna Schneider was born on June 19, 1926, in Irvington, New Jersey. Her family lived in South Orange, New Jersey and her father was a dentist and her mother was a teacher. She had a younger brother who died from polio at the age of five. She loved swimming, sailing, canoeing, and was interested in science at an early age. According to one source, she read the biography of Marie Curie which suggested to her that she could succeed in a scientific fie ...

Stored Program Control
Stored program control (SPC) is a telecommunications technology for telephone exchanges. Its characteristic is that the switching system is controlled by a computer program stored in a memory in the switching system. SPC was the enabling technology of electronic switching systems (ESS) developed in the Bell System in the 1950s, and may be considered the third generation of switching technology. Stored program control was invented in 1954 by Bell Labs scientist Erna Schneider Hoover, who reasoned that computer software could control the connection of telephone calls. History Proposed and developed in the 1950s, SPC was introduced in production electronic switching systems in the 1960s. The 101ESS private branch exchange (PBX) was a transitional switching system in the Bell System to provide expanded services to business customers that were otherwise still served by an electromechanical central office switch. The first central office switch with SPC was installed at Morris, Ill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irvington, New Jersey
Irvington is a Township (New Jersey), township in Essex County, New Jersey, Essex County, New Jersey, United States. Per the 2020 United States census, 2020 census, the population was 61,176. The township had the ninth-highest property tax rate in New Jersey, with an equalized rate of 4.890% in 2020, compared to 2.824% in the county as a whole and a statewide average of 2.279%. History Clinton Township, Essex County, New Jersey, Clinton Township, which included what is now Irvington, Maplewood, New Jersey, Maplewood and parts of Newark and South Orange, New Jersey, South Orange, was created on April 14, 1834. The area was known as ''Camptown'' until the mid-1800s. In 1850, after Stephen Foster published his ballad, ''Camptown Races'', residents were concerned that the activities described in the song would be associated with their community. The town was renamed, ''Irvingtown'', in honor of Washington Irving. Irvington was incorporated as an independent village on March 27, 187 ...

Symbolic Logic
Mathematical logic is the study of formal logic within mathematics. Major subareas include model theory, proof theory, set theory, and recursion theory. Research in mathematical logic commonly addresses the mathematical properties of formal systems of logic such as their expressive or deductive power. However, it can also include uses of logic to characterize correct mathematical reasoning or to establish foundations of mathematics. Since its inception, mathematical logic has both contributed to and been motivated by the study of foundations of mathematics. This study began in the late 19th century with the development of axiomatic frameworks for geometry, arithmetic, and analysis. In the early 20th century it was shaped by David Hilbert's program to prove the consistency of foundational theories. Results of Kurt Gödel, Gerhard Gentzen, and others provided partial resolution to the program, and clarified the issues involved in proving consistency. Work in set theory show ...

Scientists At Bell Labs
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Higher Education In The United States
Higher education in the United States is an optional stage of formal learning following secondary education. Higher education is also referred as post-secondary education, third-stage, third-level, or tertiary education. It covers stages 5 to 8 on the International ISCED 2011 scale. It is delivered at 4,360 Title IV degree-granting institutions, known as colleges or universities. These may be public or private universities, research universities, liberal arts colleges, community colleges, or for-profit colleges. US higher education is loosely regulated by the government and by several third-party organizations. In Spring 2022, about 16 million students 9.6 million women and 6.6 million men enrolled in degree-granting colleges and universities in the U.S. Of the enrolled students, 45.8% enrolled in a four-year public institution, 27.8% in a four-year private institution, and 26.4% in a two-year public institution.

The College Of New Jersey
The College of New Jersey (TCNJ) is a public university in Ewing Township, New Jersey. It is part of New Jersey's public system of higher education. Established in 1855 as the New Jersey State Normal School, TCNJ was the first normal school, or teaching college, in the state of New Jersey and the fifth in the United States. It was originally located in Trenton proper and moved to its present location in adjacent Ewing Township during the early to mid-1930s. Since its inception, TCNJ has undergone several name changes, the most recent being the 1996 change from Trenton State College to its current name. The institution is organized into seven schools, all of which offer bachelor's degree programs and several of which offer master's degree programs. Emphasis is placed on liberal arts education via the college's general education requirements. Much of TCNJ is built in Georgian colonial revival architecture style on 289 tree-lined acres.

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...
