As you walk around Manhattan this weekend and occasionally toss your gaze up to the mighty Empire State Building, you will see that it is lit in pink, lavender, and white. What for, you may ask. It's not for some lady-cause or Grimace festival. No, the tower will be lit to celebrate Mariah Carey's fancy new science album "E=MC2". The Earth gets one green-lit day and Mariah gets a whole multi-color weekend.
