Sir Isaac Newton (4 January 1643 – 31 March 1727 [OS: 25 December 1642 – 20 March 1726])was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian who is considered by many scholars and members of the general public to be one of the most influential people in human history. His 1687 publication of the Philosophiæ Naturalis Principia Mathematica (usually called the Principia) is considered to be among the most influential books in the history of science, laying the groundwork for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the scientific revolution.

Max Planck (April 23, 1858 – October 4, 1947) was a German physicist. He is considered to be the founder of the quantum theory, and thus one of the most important physicists of the twentieth century. Planck was awarded the Nobel Prize in Physics in 1918.

Niels Henrik David Bohr (Danish pronunciation: [nels ?b?o???]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. Bohr mentored and collaborated with many of the top physicists of the century at his institute in Copenhagen. He was part of a team of physicists working on the Manhattan Project. Bohr married Margrethe Nørlund in 1912, and one of their sons, Aage Bohr, grew up to be an important physicist who in 1975 also received the Nobel prize. Bohr has been described as one of the most influential physicists of the 20th century.

Enrico Fermi (29 September 1901 – 28 November 1954) was an Italian physicist, particularly known for his work on the development of the first nuclear reactor, and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. Awarded the Nobel Prize in Physics in 1938 for his work on induced radioactivity, Fermi is widely regarded as one of the leading scientists of the 20th century and the father of the Atomic Bomb, highly accomplished in both theory and experiment. Fermium, a synthetic element created in 1952, the Fermi National Accelerator Lab, the Fermi Gamma-ray Space Telescope, the Enrico Fermi Nuclear Generating Station, and a type of particles called fermions are named after him.

Lorenzo Romano Amedeo Carlo Bernadette Avogadro di Quaregna e Cerreto, Count of Quaregna and Cerreto (9 August 1776, Turin, Piedmont – 9 July 1856) was an Italian savant. He is most noted for his contributions to molecular theory, including what is known as Avogadro's law. In tribute to him, the number of elementary entities (atoms, molecules, ions or other particles) in 1 mole of a substance, 6.02214179(30)×10^23, is known as the Avogadro constant.

Werner Heisenberg (5 December 1901 – 1 February 1976) was a German theoretical physicist who made foundational contributions to quantum mechanics and is best known for asserting the uncertainty principle of quantum theory. In addition, he made important contributions to nuclear physics, quantum field theory, and particle physics.

Leonardo di ser Piero da Vinci (April 15, 1452 – May 2, 1519) was an Italian polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer. Leonardo has often been described as the archetype of the Renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention. He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote". Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time

J. Robert Oppenheimer (April 22, 1904 – February 18, 1967) was an American theoretical physicist and professor of physics at the University of California, Berkeley. He is best known for his role as the scientific director of the Manhattan Project, the World War II project that developed the first nuclear weapons. In reference to the Trinity test in New Mexico, where the first atomic bomb was detonated. Oppenheimer famously recalled the Bhagavad Gita: "If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendor of the mighty one." and "Now I am become Death, the destroyer of worlds."

Sigmund Freud , born Sigismund Schlomo Freud (6 May 1856 – 23 September 1939), was an Austrian neurologist who founded the psychoanalytic school of psychiatry. Freud is best known for his theories of the unconscious mind and the defense mechanism of repression, and for creating the clinical practice of psychoanalysis for treating psychopathology through dialogue between a patient, technically referred to as an "analysand", and a psychoanalyst. Freud redefined sexual desire as the primary motivational energy of human life, developed therapeutic techniques such as the use of free association, created the theory of transference in the therapeutic relationship, and interpreted dreams as sources of insight into unconscious desires. He was an early neurological researcher into cerebral palsy, and a prolific essayist, drawing on psychoanalysis to contribute to the history, interpretation and critique of culture.

Jules Gabriel Verne; February 8, 1828 – March 24, 1905) was a French Breton author who pioneered the science-fiction genre. He is best known for novels such as Twenty Thousand Leagues Under the Sea (1870), A Journey to the Center of the Earth (1864), and Around the World in Eighty Days (1873). Verne wrote about space, air, and underwater travel before air travel and practical submarines were invented, and before practical means of space travel had been devised. He is the third most translated individual author in the world, according to Index Translationum. Some of his books have been made into films. Verne, along with Hugo Gernsback and H. G. Wells, is often popularly referred to as the "Father of Science Fiction"

Albert Einstein (pronounced /?ælb?rt ?a?nsta?n/; German: [?alb?t ?a?n?ta?n] ( listen); 14 March 1879 – 18 April 1955) was a theoretical physicist, philosopher and author who is widely regarded as one of the most influential and best known scientists and intellectuals of all time. He is often regarded as the father of modern physics. He received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."
