Albert Einstein

Dylan Malloch laments that understanding climate change is difficult, with the forecasts sometimes appearing to be contradictory or having a bit both ways, and therefore seeming all rather confusing! It’s easy to sympathise with him. Unfortunately, this is the nature of science.

Let’s consider another example. Newton’s laws of physics work just fine for the everyday world, but if we tried to use them in the timing system of our global positioning satellites, the resulting drift error would be about 10 kilometres every day.

So, the engineers at GPS mission control need to use Einstein’s relativistic theories to make sure your iPhone tells you precisely where you are, whenever you want to know. Similarly, neither Newton’s or Einstein’s equations allow scientists to properly predict the subatomic interactions within the electronics of satellites or iPhones. For that, you need to reference the weird world of quantum mechanics.
