Damek and I are currently reading a book titled 'Mathematicians Are People, Too; Stories from the Lives of Great Mathematicians' by Luetta Reimer & Wilbert Reimer. He (and I) are really enjoying it. This morning while reading about Joseph Louis Lagrange, who was a french physicist and mathematician, we got out the globe to locate Dunkirk, France and Barcelona, Spain. According to the book, Lagrange led the Units and Measures Committee who decided to determine the length that is one ten-millionth of the distance between the North Pole and the equator (which would later be the unit of length known as the meter). In problem solving measuring the distance, the French Academy of Sciences authorized a precise measurement of the meridian between Dunkirk, France and Barcelona, Spain. Given the measurements, scientists used astronomical calculations to determine the total length and to find the length of the first meter.
A couple hours later, Kyan picked up the globe started studying it, pointing to different places and guessing what they were. After a few minutes of looking at the North and South poles, he said "it looks like the Antarctic is warmer than the Arctic". We looked it up here and found that he was right:)
