Occasionally, there were prizes, such as that given to John Harrison in the 18th century, for solving the so-called longitude problem, but prizes were only given after the fact, when they were given at all.
Ocazional, existau premii, ca cel primit de John Harrison în secolul XVIII, pentru rezolvarea așa-zisei probleme a longitudinii, dar premiile erau acordate după experiment, dacă, de fapt, erau oferite.
