Ars Technica – The complicated history of simple scientific facts

Sometimes, even as a person pisses you off, they make a point that you can’t ignore. In a recent forum discussion that I was involved in, scientists were accused of making pronouncements from on high. The argument was that scientists jump to a conclusion that seems desirable to them, and then treat it as an infallible truth.

Of course, my initial reaction was to pronounce that I, as a practicing scientist, never make pronouncements. But, looking at my articles from the perspective of someone who really knows absolutely nothing about science—as a practice or as a body of knowledge—I can see how one could see little beyond a list of assertions. The truth is more complicated, of course, but it’s a truth that science writers find challenging to convey. Science is impossibly broad, and the leading edge sits, precariously balanced, on a huge, solid, and above all, old body of knowledge. To illustrate this problem, I am going to tell you the story about how the speed of light came to be the ultimate speed limit for the entire universe.

Thus begins Ars’s latest article on Science, and how something becomes a scientific fact.  This meshes quite nicely with my blog post from last week.
