"When you are courting a nice girl, an hour seems like a second. When you sit on a red-hot cinder, a second seems like an hour. That's relativity."
— Albert Einstein
“What is it with science these days? Everyone is so quick to believe in it, in all these new scientific discoveries, new pills for this, new pills for that. Get thinner, grow hair, yada, yada, yada, but when it requires a little faith in something you all go crazy.' He shook his head, 'If miracles had chemical equations then everyone would believe.”
― Cecelia Ahern, The Gift
