Harte's hypothesis was that acid rain was falling as winter snow on the Rockies. The acid was released when the snow melted in the spring.
In 1924, Aleksandr Oparin (and John Haldane separately in 1929) hypothesized that the formation of amino acids and proteins from non-living chemicals, a process known as "abiogenesis", could have occurred in the conditions present shortly after the formation of the Earth. This process would not be observable now because other organisms would absorb created proteins, which would be rare anyway due to the higher concentration of oxygen in Earth's current atmosphere. Oparin's Hypothesis (also called the Oparin-Haldane Hypothesis) remains unconfirmed as a possible source for life on Earth. Experiments that simulated past conditions on the Earth did generate some simple amino acids, but not in the form or complexity of organic proteins.
John Harte's data showed the volume-weighted average pH for summer events was 4.61, for winter events was 5.11 and for the entire period was 4.91. Within the watershed, both low- and medium-alkalinity surface waters exist.

John Adams served as US president from 1797 to 1801.
It was actually been discovered for thousands of years! John Dice just discovered it but it was discovered for thousands of years. :)

Dr. John Harte hypothesized that melting snow causes acidity in the ponds he was studying. His data indicated that there was a drop in the pH level of the ponds after the snow melted, which proved his hypothesis.

"What does hypothesis mean?" "What is your hypothesis on the John F. Kennedy assassination?" "Can you come up with a hypothesis for how life is on Earth?"
A hypothesis is an "educated guess". An example of how it could be used: John needed to test his hypothesis about molecular degenaration.
The atomic theory is about two centuries now. John Dalton, one of the most vibrant scientists in his time, postulated the atomic theory in the year 1808 making it exactly 2 centuries and 2 years now.
