Answer 1

Dear student
In about 200 BC the Greek Eratosthenes devised an algorithm for calculating primes called the Sieve of Eratosthenes.
The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American aviators, engineers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane.
