According to guff these scientists could be our generation's Einsteins based on their work.
K. Eric Drexler
Known as the father of nanotechnology, K. Eric Drexler popularized the prospects placed in the folds of realism at the nanoscale. He carry out his major work in the field of the nanotechnology in the 70s and 80s, and printed a revolutionary book in '92 that split the case wide open. As nanotechnology improves and enhances, we owe many thanks to Drexler for his frontiersmen work. You can read a complete bio of K. Eric Drexler here.
Sir Andre Geim
In 2010, Andre Geim was granted the Nobel Prize along with Konstantin Novesolov for their combined work on graphene, the ultra-fine, ultra-strong material that can transform the material sciences completely.
