Erdős conjecture on cosmology
Jun. 21st, 2013 12:53 pm"Paul Erdos, one of the finest mathematicians of the 20th century, once claimed to be 2.5billion years old. His reasoning? When he was a child, he was told that the Earth was 2 billion years old. But many years later in 1970, scientists said the Earth was 4.5 billion years old. That was Erdos’ humorous way of saying we don’t have all the answers and, in light of new evidence, we must discard some beliefs learned in childhood." (src)
