It has always amused me that the US election date is the same as that of Australia's greatest horse race. Here's the official photo finish from this year's Melbourne Cup; Viewed nosed Bauer out by about one cm on a 3200m track. That's about 3 parts in a million. For comparison to the American horse race, if 100 million people vote today, that would be a 300 ballot difference. In science, it is extremely difficult to measure most things to that precision.
The observant among you will note that in this picture, the black horse has nosed out the one with gray hair. Interpretation of that point is left as an exercise to the reader.
Science resumes tomorrow.
