child produgies are children who demonstrate talents at a very young age .
However , some child geniuses lose their talents by adulthood . Mathematical geniuses are often able to do complicated calculations in their heads in just a few seconds . this is particularly remarkable when they are dealing with numbers that have been selected at random by a computer .
musical geniuses , like mozart , are often able to learn to play new pieces of music on a variety of instruments very quickly . mozart was certainly the most talented composer of his time
