Thursday, March 14, marks the 140th anniversary of the eminent physicist Albert Einstein. The German-born scientist is known for his works that had a major impact on physics. He died April 18, 1955, in New Jersey from an abdominal aortic aneurysm.

Einstein was born on March 14, 1879, in Ulm, Germany. He won the Nobel Prize in 1921 for his work developing the theory of general relativity and advancing the law of photoelectric effect.

Here are some quotes from Einstein, courtesy Goodreads and Brainy Quote, to celebrate his birthday.

1. “Look deep into nature, and then you will understand everything better.”

2. “Anyone who has never made a mistake has never tried anything new.”

3. “We cannot solve our problems with the same thinking we used when we created them.”

4. “You can't blame gravity for falling in love.”

5. “To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.”

6. “Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”

7. “If you can't explain it to a six year old, you don't understand it yourself.”

8. “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.”

9. “Science without religion is lame, religion without science is blind.”
