These two are among the fastest and busiest metro systems in the world, and are famous for rich decorations and unique designs of their stations, which is a common tradition on Russian metros and railways.
• Science and technology
Science and technology in Russia blossomed since the Age of Enlightenment, when Peter the Great founded the Russian Academy of Sciences and Saint Petersburg State University, and polymath Mikhail Lomonosov established the Moscow State University, paving the way for a strong native tradition in learning and innovation. In the 19th and 20th centuries the country produced a large number of notable scientists and inventors.
The Russian physics school began with Lomonosov who proposed the law of conservation of matter preceding the energy conservation law. Russian discoveries and inventions in physics include the electric arc, electrodynamical Lenz's law, space groups of crystals, photoelectric cell, Cherenkov radiation, electron paramagnetic resonance, heterotransistors and 3D holography. Lasers and masers were co-invented by Nikolai Basov and Alexander Prokhorov, while the idea of tokamak for controlled nuclear fusion was introduced by Igor Tamm, Andrei Sakharov and Lev Artsimovich, leading eventually the modern international ITER project, where Russia is a party.
