I am hoping my time in quarantine is much shorter than 18 months. I am not sure I would quite last that long. I am quite positive though that if I spent 18 years in quarantine, I would not invent anything as important as calculus or propose theories which will be discussed almost 400 years later. I like to think I have some intelligence, but I do know my limitations. Any discoveries I make will be a surprise to me only. Unlike Isaac Newton, my discoveries won't surprise the world.
