Security is sleeping in the back seat of the car...When you're a little kid, and you've ben somewhere with your Mom and Dad, and it's night, and you're riding home in the car, you can sleep in the back seat...You don't have to worry about anything...Your Mom and Dad are in the front seat, and they do all the worrying...But it doesn't last! Suddenly, you're grown up, and it can never be that way again!
我们说的每一个词都承载着我们的历史和未来的希望。
跨学科的合作对于解决科学中最具挑战性的问题至关重要。
世界上有开朗的悲观主义者吗?我就是这样的人。
