Galileo still right about gravity

1 Comment and 4 Shares

If you believe in gravity, then you know that if you remove air resistance, a bowling ball and a feather will fall at the same rate. But seeing it actually happen, in the world's largest vacuum chamber (122 feet high, 100 feet in diameter), is still a bit shocking.

In the late 1500s, Galileo was the first to show that the acceleration due to the Earth's gravity was independent of mass with his experiment at the Leaning Tower of Pisa, but that pesky air resistance caused some problems. At the end of the Apollo 15 mission, astronaut David Scott dropped a hammer and a feather in the vacuum on the surface of the Moon:

Chipotle Cup Stories: Beyonce and Solange

2 Comments and 3 Shares

Beyonce is mad at Solange for not sticking to the plan. What plan? I don't want to say too much, but it involves Chipotle.

"You just stood there. I was defending you."

"Do I need defending?"

"That's not the point. He is a monster."

"He is my husband."

Beyoncé looked away, out the window at the people and the buildings, as they sped across 59th St. "I know who I married. That was my decision and I'll live with it."

"Of course you take his side."

"Excuse me?" Beyoncé turned to face her sister. "Beyoncé is on Beyoncé's side. Always. Trust that."
