Is there any scientific discovery with a longer gap between prediction and validation?

I guess the prediction was made in his 1798 book:

John Adams was the second US President. 5.3 million people lived in America.

Makes me want to learn more math.

Laplace had an amazing mind. He connected so many dots, and everything I've done in the last four years with respect to digital signal processing ends up rooted in something he discovered or postulated or analyzed. Fascinating, but not too surprising, that he shows up in the weather as well.

Not sure if it's completely related, but I found the phenomena of the North Atlantic Oscillation [1] to be particulary useful in predicting long-term weather around the South of Norway. This time around, in December 2019, I predicted a rather cold summer in Norway. I made that prediction because the winter was particularly warm and snow-less in the South East between late 2019 and early 2020. For the most part I've been correct. Except a few heat waves this summer has been pretty cold. But the effects of global warming persists, and it would seem the Autumn will be pretty nice here in Oslo.

A friend of mine wondered what the RATIO between the four modes of pressure waves are. Waves are essentially a frequency (like pitch), and he was wondering if the ratio between these “frequencies” constitute a similar ratio between the pitches in a chord.

Do you want to count Democritus and indivisible constituents of matter?

Holy cow, he predicted way more than just indivisible constituents of matter [1]:

> The theory of Democritus held that everything is composed of "atoms", which are physically, but not geometrically, indivisible; that between atoms, there lies empty space; that atoms are indestructible, and have always been and always will be in motion; that there is an infinite number of atoms and of kinds of atoms, which differ in shape and size.

The accuracy is uncanny.
