It is surprising to realise that Balmer was sixty years old when he wrote the paper for which he is famous on the spectral lines of the hydrogen atom and that he was seventy-two when he wrote his only other work on this topic.
Ito ay kamangha-mangha na realise na Balmer ay animnapu years old kapag wrote niya ang papel para sa kung saan ay siya ang bantog sa multo linya ng haydrodyen atom at na siya ay pitungpu't-dalawang kapag siya wrote kanyang lamang ng ibang trabaho sa paksang ito.
