None of them knew they were robots

Ok, we've already established that scientists are clever. We get it. Now, lets ponder how on earth they figure some of these things out. Scientist have recently discovered that they could help stroke victims recover more quickly by implanting testicle cells into patients' brains. What?! I want to know what possessed scientists to induce strokes in rats, then put testicle cells in their brain.

In mathematics news, there are signs that the Riemann hypothesis (probably the most famous problem in mathematics) is close to being proven. The Riemann hypothesis has to do with Prime Numbers and their distribution (it is speculated that their distribution is chaotic). Apparently, those clever scientists I keep marvelling at have found a link between the Riemann hypothesis and the physical world. If this connection proves to be true, it would be a huge boost (there are tons of proofs in mathematics that start: Assuming the Riemann hypothesis is true...) to our understanding of the universe...
