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.
Povremeno, dodjeljivale su se nagrade, poput one koju je dobio  John Harrison u 18. stoljeću, zbog rješavanja tzv. problema longitude, ali nagrade su dodjeljivane samo nakon pronalazaka, kad su uopće dodjeljivane.
