What do you know about the Nobel Prize
The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel’s will of 1895, are awarded to “those who, during the preceding year, have conferred the greatest benefit to humankind”.
Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.
