About the Number 174 (one hundred seventy-four)

MathBabbler visited Google on Pi Day 2009 expecting to find a modified logo to celebrate Pi Day, but instead the Google logo had been modified to honor Italian astronomer Giovanni Schiaparelli. Clicking the logo took users to a webpage that stated the following: "In 1890, Italian astronomer Giovanni Schiaparelli drew this map of Mars. Today, on his 174th birthday, we are excited to include his work with many other new features for Mars in Google Earth."
