<p>Oh my, this is one of my seminal childhood memories. For some reason my family was standing around waiting for a plane to land. (Dad was aerospace engineer, I was about 9 so in Albuquerque…don’t know why I was the kid he focused on). He asked me if I could figure out how tall Mt Sandi was based on the fact that he knew the flagpole was 50’
high and the shadow of the mountain was falling across the field. We paced off the triangle and although I didn’t get the arithmetic I really got the geometry. Kids need more hands on math in the early days, and less computers. There, I said it.</p>
