Albert Einstein delivering his Nobel Lecture to the Nordic Assembly of Naturalists in Gothenburg, Sweden, 11 July 1923.

Einstein was awarded the 1921 #NobelPrize in Physics for his many contributions to theoretical physics, and especially for his discovery of the law of the photoelectric effect. The photoelectric effect is very important for our daily life. It is the basis for photosynthesis, which is like a very effective solar cell where sunlight is absorbed by plants to make them grow. The effect also forms the basis for a variety of devices such as photodiodes, which are used in light detection within fibre optics, telecommunications networks, solar cells, imaging and many other applications.
