What do you think about the astonishing result: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + ... = -1/12 ?

Dear researchers: As counterintuitive as it can be, the infinite sum of all the integers : 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 ... to infinity can be understood as = -1/12 i.e. Sum(all...

How thick is the Al2O3 thin film layer grown on Aluminum due to environment exposure? What is its Growth Rate ?

Dear colleagues: When you have an Aluminum plate, and then, lets say you sand its surface with a sandpaper, you remove its native Al2O3 thin layer previously formed on the surface. Instantly,...
