Hartley Rogers Jr.
Hartley Rogers Jr. (July 6, 1926 – July 17, 2015) was a mathematician who worked in computability theory, and was a professor in the Mathematics Department of the Massachusetts Institute of Technology. Biography Born in 1926 in Buffalo, New York, he studied under Alonzo Church at Princeton, and received his Ph.D. there in 1952. He served on the MIT faculty from 1956 until his death, July 17, 2015. He is survived by his wife, Dr. Adrianne E. Rogers, by his three children, Hartley R. Rogers, Campbell D.K. Rogers, and Caroline R. Broderick, and by his 10 grandchildren. At MIT he had been involved in many scholarly extracurricular activities, including running SPUR (Summer Program in Undergraduate Research) for MIT undergraduates, overseeing the mathematics section of RSI (Research Science Institute) for advanced high school students, and coaching the MIT Putnam exam team for nearly two decades starting in 1990, including the years 2003 and 2004 when MIT won for the first time since ...

Computability Theory
Computability theory, also known as recursion theory, is a branch of mathematical logic, computer science, and the theory of computation that originated in the 1930s with the study of computable functions and Turing degrees. The field has since expanded to include the study of generalized computability and definability. In these areas, computability theory overlaps with proof theory and effective descriptive set theory. Basic questions addressed by computability theory include: * What does it mean for a function on the natural numbers to be computable? * How can noncomputable functions be classified into a hierarchy based on their level of noncomputability? Although there is considerable overlap in terms of knowledge and methods, mathematical computability theorists study the theory of relative computability, reducibility notions, and degree structures; those in the computer science field focus on the theory of subrecursive hierarchies, formal methods, and formal languages.

Andrew Kahr
Andrew Seth Kahr is an American mathematician and financial consultant. He was the founder and CEO of First Deposit Corp., which was later acquired by Providian. Kahr grew up in New York City, where he attended the Fieldston School of the Ethical Culture Society. He went to Harvard University in 1957 and graduated three years later, in 1960. He earned his Ph.D. in mathematics in 1962 at the Massachusetts Institute of Technology. His thesis was "A Minimal Reduction Class for the Entscheidungsproblem". Following that he attended Harvard Business School. During the 1970s Kahr worked at Merrill Lynch, where he gained recognition for developing the cash management account, a brokerage account that automatically swept investment income into a money market fund and could be used for payments like a bank account. He developed a similar product, the Schwab One account, for Charles Schwab. Kahr also established the first non-bank bank, whereby a bank was stripped of one of its traditional ...

21st-century American Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius ( AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman empero ...

Mathematics Magazine
''Mathematics Magazine'' is a refereed bimonthly publication of the Mathematical Association of America. Its intended audience is teachers of collegiate mathematics, especially at the junior/senior level, and their students. It is explicitly a journal of mathematics rather than pedagogy. Rather than articles in the terse "theorem-proof" style of research journals, it seeks articles which provide a context for the mathematics they deliver, with examples, applications, illustrations, and historical background. Paid circulation in 2008 was 9,500 and total circulation was 10,000. ''Mathematics Magazine'' is a continuation of ''Mathematics News Letter'' (1926-1934) and ''National Mathematics Magazine'' (1934-1945.) Doris Schattschneider became the first female editor of ''Mathematics Magazine'' in 1981. .. The MAA gives the Carl B. Allendoerfer Awards annually "for articles of expository excellence" published in ''Mathematics Magazine''. See also *''American Mathematical Mont ...
