Why do we stress children’s mathematics so much? It is because one or two simple discoveries in mathematics can feed thousands of scientific papers for many years. For example, please take a look at this 1994 paper by Mr. Burrows and Mr. Wheeler, which led to FM index and very powerful nucleotide search and assembly algorithm.
The algorithm described here was discovered by one of the authors (Wheeler) in 1983 while he was working at AT&T; Bell Laboratories, though it has not previously been published.
The math behind it is so simple that Wheeler did not bother to publish it for 11 years !!
