He advanced the cell theory with his conclusion that cells could only come from other cells: Anton van Leeuwenhoek Rudolph Virchow Theodor Schwann Robert Hooke. string theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity.The name string theory comes from the modeling of subatomic particles as tiny one-dimensional “stringlike” entities rather than the more conventional approach in which they are modeled as zero-dimensional point particles.
