Best two scientific inventions to date (to me)

The mountain bike ( multiple folks in 1980s)

The crystalline silicon solar cell (bell labs 1948)

The mountain bike requires nothing but you and can cross ANY TERRAIN

The solar cell will make DC current with only sunlight and has NO breakdown mechanism
