My paradigm shift
Here’s a blog to jumpstart the old brain cells, or kick them into touch. A paradigm shift is a fundamental change in how we think about and understand life, the universe and everything. The replacement of Ptolemy’s earth-centred universe with Copernicus’ sun-centred system is one example; Newtonian mechanics given the heave-ho by Einstein’s relativity is another. If you prefer, it’s when the ultimate answer is no longer 42; it’s 51.
