german-born theoretical physicist (1879–1955)
Albert Einstein (14 March 1879 – 18 April 1955) was a German theoretical physicist, widely acknowledged to be one of the greatest physicists of all time. Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Together, relativity and quantum mechanics are the two pillars of modern physics. He won the 1921 Nobel Prize in Physics for his explanation of the photoelectric effect.

Dear Fräulein,
The desire to write you has finally conquered the guilty conscience I’ve had about not responding to your letter for such a long time, and which has allowed me to avoid your critical eye. But now, even though you are understandably angry with me, you must at least give me credit for not adding to my offense by hiding behind feeble excuses, and for asking you simply and directly for forgiveness and — for an answer as soon as possible.
A human being is a part of the whole, called by us 'Universe', a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.
