  Russia spent about 1% of its GDP on research and development in 2019, with the world's tenth-highest budget. It also ranked tenth worldwide in the number of scientific publications in 2020, with roughly 1.3 million papers. Since 1904, Nobel Prize were awarded to 26 Soviets and Russians in physics, chemistry, medicine, economy, literature and peace. Russia ranked 60th in the Global Innovation Index in 2024, down from 45th in 2021.
  
  Since the times of Nikolay Lobachevsky, who pioneered the non-Euclidean geometry, and Pafnuty Chebyshev, a prominent tutor, Russian mathematicians became among the world's most influential. Dmitry Mendeleev invented the Periodic table, the main framework of modern chemistry. Nine Soviet and Russian mathematicians have been awarded with the Fields Medal.
