Bohužel ale pro něj nenašli využití a transformace náboženství tomu taky dvakrát nepomohla, takže novinka zapadla v dějinách. V technice se stalo několik momentů, kdy myšlenky a nákresy předběhly svou dobu. Nejedná se ale o Leonarda da Vinci, ale o méně známé vynálezce mechanických počítačů a kalkulaček. Jaké? Dozvíte se v následujícím článku.
Určitě si ještě pamatujete staré krabicové monitory, které zabíraly půlku pracovního stolu, byly těžké a spotřebou se vyrovnaly celému počítači.
