Arthur Ravenel Jr. Bridge over the Cooper River, South Carolina, USA An illuminated pathway! This cable-stayed bridge has one of the largest spans in the western hemisphere and is particularly impressive in the dark when it is illuminated.  When opened in 2005, the eight-lane Arthur Ravenel Jr. Bridge replaced the two older, dilapidated bridges that previously ran over the Cooper River.  It can withstand wind speeds of over 480 km / h and 7.4 magnitude earthquakes on the Richter scale.  And that's really necessary as: ​​Many of the more than 134,000 residents of Charleston in the US state of South Carolina can still remember Hurricane Hugo, which swept across the port city in 1989.  While earthquakes do not occur particularly often in Charleston, caution is still advisable. The 1886 earthquake, with an estimated magnitude of over 7.3 almost completely destroyed the city at the time.

The Circle Bridge in Copenhagen, Denmark It’s Pi Day! Well, not that mouthwatering and cherry or berries filling pie, it's the day we celebrate the mathematical constant π. This day was chosen since today’s date (March 14) expressed numerically (in US format) matches the number’s first digits, 3.14. Pi represents the ratio of a circle’s circumference to its diameter. It can be used to compute the area and circumference of a circle, such as the circles that make up the bridge we're looking at here in Copenhagen. (Who said maths wasn't useful in the real world?) Many towns, schools, and museums mark the day with festivities based around mathematics and, of course, serving pie. We can’t think of a more delicious way to study geometry.
