Julius Axelrod (1912–2004): American Nobel Prize–winning biochemist, noted for his work on the release and reuptake of catecholamine neurotransmitters and major contributions to the understanding of the pineal gland and how it is regulated during the sleep-wake cycle.Peter Atkins (1940–): English quantum chemist and professor of chemistry at Lincoln College, Oxford in England.He was awarded the Fields Medal in 1966 and the Abel Prize in 2004. Michael Atiyah (1929-2015): British-Lebanese mathematician specialising in geometry.Asprey (1919–2005): American chemist noted for his work on actinide, lanthanide, rare earth, and fluorine chemistry, and for his contributions to nuclear chemistry on the Manhattan Project and later at the Los Alamos National Laboratory. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. Abhay Ashtekar (1949–): Indian theoretical physicist.Svante Arrhenius (1859–1927): Swedish scientist and the first Swedish Nobel Prize winner.François Arago (1786–1853): French mathematician, physicist, astronomer and politician.Jacob Appelbaum (1983–): American computer security researcher and hacker.Anderson has made contributions to the theories of localization, antiferromagnetism and high-temperature superconductivity. He was one of the recipients of the Nobel Prize in Physics in 1977.

Anderson (1923–2020): American physicist. He is professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey Jim Al-Khalili OBE (1962–): Iraqi-born British quantum physicist, author and science communicator.He is best known for describing the class of MHD waves now known as Alfvén waves. He received the 1970 Nobel Prize in Physics for his work on magnetohydrodynamics (MHD). Hannes Alfvén (1908–1995): Swedish electrical engineer and plasma physicist.He is an inventor of the heterotransistor and co-winner (with Herbert Kroemer and Jack Kilby) of the 2000 Nobel Prize in Physics. Zhores Alferov (1930–2019): Belarusian, Soviet, and Russian physicist who contributed substantially to the creation of modern heterostructure physics and electronics.He was also co-editor with Denis Diderot of the Encyclopédie. Jean le Rond d’Alembert (1717–1783): French mathematician, mechanician, physicist, philosopher, and music theorist.She was a recipient of the 2007 National Medal of Science. Fay Ajzenberg-Selove (1926–2012): American nuclear physicist who was known for her experimental work in nuclear spectroscopy of light elements, and for her annual reviews of the energy levels of light atomic nuclei.He was a co-owner of Carl Zeiss AG, a German manufacturer of research microscopes, astronomical telescopes, planetariums and other optical systems. Abbe developed numerous optical instruments. Together with Otto Schott and Carl Zeiss, he laid the foundation of modern optics. Ernst Abbe (1840–1905): German physicist, optometrist, entrepreneur, and social reformer.His primary area of research is quantum computing and computational complexity theory. Scott Aaronson (1981–): American theoretical computer scientist and faculty member in the Electrical Engineering and Computer Science department at MIT.Persons in this list are people (living or not) who both have publicly identified themselves as atheists and whose atheism is relevant to their notable activities or public life. A mere statement by a person that he or she does not believe in God does not meet the criteria for inclusion on this list. This is a list of atheists in science and technology.
