Okay, I admit to being a big fan of Shakira and her mesmerizing hips. I blame this on my physics teacher back in school. In trying to explain the concept of simple harmonic motion to us impressionable youngsters, he used the example of the sway of a woman’s hips. For you cold scientific types, the swing of a pendulum is a more commonly quoted example of simple harmonic motion or SHM. I guess that he thought that young adolescent males who have probably never seen a grandfather clock would have very little interest in pendulums. Swinging pendulums versus swinging hips – no contest, he probably thought.
So if you catch me looking at swaying hips, I am merely studying physics or so I try to tell my wife. Even as I write this the following words from the song “Girl from Ipanema” comes to mind;
“Tall and tan and young and lovely,
the Girl from Ipanema goes walking and,
when she passes, each time she passes,
I go ……aaaaaaaahhh.”
Anyway SHM or Shakira’s Hip Movements is the extreme example of Simple Harmonic Motion or SHM. For your introduction to physics, I have included two videos. The first is Shakira, herself performing during the 2006 World Cup (Soccer) and the second is a video of a bunch of Shakira wanna-be’s and some of them aren’t half bad and some of them are real funny.
The real thing.
