MEMs oscillator sensitivity to helium (helium kills iPhones)
Helium diffuses into the microscopic silicon tuning forks and causes them to lose their minds, but hydrogen doesn't. Odd. Presumably, hyrdrogen will also diffuse into silicon, I mean it diffuses into steel, but perhaps the molecular structure of the silicon isn't affected by hydrogen, but it is by helium. There isn't much difference between hydrogen and helium, both atoms are very small, but there isn't much difference between carbon 12 and carbon 13, but corn can tell the difference, so maybe that small difference is enough to bring Apple to its knees.
This is the second time I've posted a video from Applied Science.
