March 14 marks the 139th birth anniversary of the eminent physicist Albert Einstein.

Einstein is credited with discovering the theory of relativity, which forms the core of modern physics. Some of his other contributions to the world of physics — especially the mass-energy equivalence formula E=mc2 — are indispensable to aspiring scientists of our generation. He won the Nobel Prize in 1921 in the field of Physics.

Apart from his extraordinary intellect, he was also known for his quick wit and humor that were apparent in his speeches. Here are a few quotes from one of the greatest geniuses the world has produced till date, from Brainy Quote:

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

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

“The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.”

“Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.”

“Put your hand on a hot stove for a minute and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute.”
