So no excuses not to visit your in-laws this Christmas.

Trains now on Uber. T's and C's apply check the Uber app. This is

is Scientific Americans 60 Second Science. I'm Steve Mursky.

With the full month of the regular season to play the 2019 New York Yankees had set a major league

baseball record for injuries. That medical crisis led to what the online

sports publication The Athletic reported on January 3rd as quote sweeping changes end quote to their

training and strength and conditioning programs. When I read that news I thought of

course of traffic cameras which sometimes and reasonably get placed at

sites that have a disproportionate number of accidents in a given year. The fact that

there's a higher rate of accidents will be partly due to chance because it will fluctuate over the course of time.

Sometimes it will be less, sometimes it will be high.

David J. Hand on the Scientific American Science Talk podcast in 2014. He's Emeritus Professor of Mathematics and Senior Research

investigator at Imperial College London where he formerly held the chair in

Statistics. He was on the podcast to talk about the then new book The Improbability

principle, why coincidences, miracles, and rare events happen every day.

So what does the Yankees revamp training staff potentially have in common with traffic cameras?

Now if we look back at last year and identify the places which have particularly high rates of accidents,

those places, the high rate at those places will be used a sum of two things, the natural degree of dangerousness of those places, plus the chart, the fact that at that particular year just happens to be a bad year.

There was more accidents than normal at that year.

But because it's a high rate of accidents, we're now going to put a camera there.

Again, a particular year just happens to be a bad year.
