Alchemy is the study of the transmutation of materials through obscure processes. The term "transmutation" dates back to alchemy. The remaining known nuclides are known solely from artificial nuclear transmutation. The remaining nuclides are known solely from artificial nuclear transmutation. Sorcery is the knowledge of the universal points of transmutation. However, trace amounts occur naturally as a product of transmutation reactions in uranium ores. By contrast, there are radioactive decay processes that do not result in a nuclear transmutation. Nikola Tesla predicted the use of a catalyst in electric nuclear transmutation experiments in 1934. These scientists rejected transmutation of species as materialist. This encouraged early evolutionary theories on the transmutation of species. This would encourage early evolutionary theories on the transmutation of species. Soddy published "The Interpretation of Radium" (1909) and "Atomic Transmutation" (1953). Some work in nuclear transmutation had been done. In particular, they wrote refutations against the idea of the transmutation of metals. The seventeenth century saw an increase in tales of physical transmutation and projection.
