Maybe I can play the same game with the other known force, which was, at that time, known as the electromagnetic force -- we know of others today, but at that time that was the only other one people were thinking about.
Võib-olla saan ma teha sama triki teise tuntud jõuga, mis sel ajal sai olla ainult elektromagnetjõud - tänaseks me teame veel teisi, aga sel ajal oli see ainus, mis võis kõne alla tulla.
