11. The pair finally married in January 1903, and had two sons. But a few years later, the marriage faltered. Mileva, meanwhile, was losing her intellectual ambition and becoming an unhappy housewife. After years of constant fighting, the couple finally divorced in 1919. Einstein married his cousin Elsa the same year.
 
12. Einstein’s new personal chapter coincided with his rise to world fame. In 1915, he had published his General Theory of Relativity, which provided a new interpretation of gravity. An eclipse of the sun in 1919 brought proof that it was accurate. Einstein had correctly calculated in advance the extent to which the light from fixed stars would be deflected through the sun’s gravitational field. The newspapers proclaimed his work as “a scientific revolution.”

13. Einstein received the Nobel Prize for Physics in 1921. He was showered with honours and invitations from all over the world, and lauded by the press.
Explanation:
 
After becoming financially stable, Einstein married Mileva Maric in January \(1903\) and had two sons. It was a beautiful and blissful period for them at the start of their marriage. However, as years passed, their marriage became weak. Mileva Maric was talented, but she started losing her intellectual ambition and became a miserable housewife. Mileva was unhappy with her marriage, and she could not achieve her career dreams, so, finally, in \(1919\), both separated after prolonged fighting. Also, the major reason for their separation was Einstein’s relationship with his cousin Elsa.

Einstein new theory had brought him worldwide recognition. He published “General Theory of Relativity” in \(1915\), which gave a new interpretation of gravity. A solar eclipse in \(1919\) proved his general theory of gravity was correct. A solar eclipse occurs when the moon passes in front of the sun, blocking it out partially or wholly.

In \(1915\), Albert Einstein had calculated and predicted that a solar eclipse would occur in \(1919\). As per his predictions, a solar eclipse formed. The scientists’ measurements during the eclipse showed that, astoundingly, Einstein’s predictions were indeed correct. ‘Einstein had accurately predicted the sun’s gravity would bend the light of another star’ (*M. L., Pg. 44). Later his work was hailed as a “scientific revolution” by the newspaper.

Albert Einstein received the Nobel Prize in Physics in \(1921\). The Nobel Prize was given in honour of Alfred Nobel, a well-known Swedish scientist. It was established in the year \(1895\). The first Nobel Prize was granted in \(1901\). Later Einstein was honoured and was invited to various places all over the world. Also, he was praised by the press.
