• 1931
  • In 1931, mathematician and logician Kurt Gödel proved that any effectively generated theory capable of proving basic arithmetic cannot be both consistent and complete. (wikipedia.org)
  • Physical
  • Correct interpretation of flow images requires knowledge of physical and technical factors that influence the Doppler signal. (bmj.com)
  • Physicists working in the area of thermodynamics study heat from a number of perspectives, including specific heat, or the amount of energy required to change the temperature of a substance, and calorimetry, the measurement of changes in heat as a result of physical or chemical changes.

  • experimental
  • Towards the end of 1942 the previously experimental non-Morse transmissions from teleprinter cipher machines were being received in greater numbers by the British Signals Intelligence collection sites. (wikipedia.org)
  • research
  • Johnson decided on a career as a research mathematician, although this was a difficult field for African Americans and women to enter. (wikipedia.org)
  • Originally assigned to the West Area Computers section supervised by mathematician Dorothy Vaughan, Johnson was reassigned to the Guidance and Control Division of Langley's Flight Research Division. (wikipedia.org)
  • He stressed the role of nonverbal factors in the process of education and upbringing, which he considered to be so crucial that he began to focus on them in his scientific research. (wikipedia.org)
  • To tackle this sustainability challenge, the Hartree Centre is carrying out research which takes a holistic view of parallel computing systems, including the optimisation of software to make it run more efficiently, low power architectures, data storage, cooling methods and other factors. (wikipedia.org)
  • human
  • We have recently initiated the Human Functional Genomics Project (HFGP), which aims to understand the genetic and non-genetic factors influencing human immune responses (Netea et al . (utwente.nl)
  • He argued that while a formal proof system cannot prove its own consistency, Gödel-unprovable results are provable by human mathematicians. (wikipedia.org)
  • He takes this disparity to mean that human mathematicians are not describable as formal proof systems, and are therefore running a non-computable algorithm. (wikipedia.org)
  • The essence of Penrose's argument is that while a formal proof system cannot, because of the theorem, prove its own incompleteness, Gödel-type results are provable by human mathematicians. (wikipedia.org)
  • He takes this disparity to mean that human mathematicians are not describable as formal proof systems and are not running an algorithm, so that the computational theory of mind is false, and computational approaches to artificial general intelligence are unfounded. (wikipedia.org)
  • made
  • Katherine Coleman Goble Johnson (born August 26, 1918) is an African-American mathematician who made contributions to the United States' aeronautics and space programs with the early application of digital electronic computers at NASA. (wikipedia.org)
  • Twelve were made at the Mawdsley engineering factory in Dursley, Gloucestershire, but turned out to be unreliable, so the other stream of development at the British Tabulating Machine Company at Letchworth was preferred. (wikipedia.org)
  • back
  • The origins of pneumatics can be traced back to the first century when ancient Greek mathematician Hero of Alexandria wrote about his inventions powered by steam or the wind. (wikipedia.org)
  • possible
  • Portable pneumatic tools and small vehicles, such as Robot Wars machines and other hobbyist applications are often powered by compressed carbon dioxide, because containers designed to hold it such as soda stream canisters and fire extinguishers are readily available, and the phase change between liquid and gas makes it possible to obtain a larger volume of compressed gas from a lighter container than compressed air requires. (wikipedia.org)
  • case
  • Drs Philip Levine and Rufus Stetson published a first case report on the clinical consequences of non-recognized Rh factor, hemolytic transfusion reaction and hemolytic disease of the newborn in its most severe form. (wikipedia.org)
  • He factors some of the dimensions (base domains, like a quantifier lattice, a (deep) case[disambiguation needed] lattice, et al. (wikipedia.org)
  • field
  • The conversion factor is 108, since flux is the integral of field over an area, area having the units of the square of distance, thus 104 (magnetic field conversion factor) times the square of 102 (linear distance conversion factor, i.e., centimetres per meter). (wikipedia.org)
  • data
  • The data comprise the cytokine response of three cohorts of 500 (500FG cohort), 200 (200FG) and 300 (300RO) individuals of Western-European and Eastern-European ancestry, linked to genetic, microbial and environmental factors. (utwente.nl)
  • In 2002 his Celera group in collaboration with the company ClearForrest won the ACM KDD Cup - the top international data mining/machine learning competition - the challenge then was the automatic annotation of a section of the Drosophila genome. (uic.edu)
  • problems
  • They posed a thousand random optimization problems to the machine, and measured how long it took to solve them, compared with a classical PC. (csmonitor.com)
