Professional scientist here. I would take a table of logarithms. In a world without computers, the logarithm table and slide rule are the essential tools of how things got built. We built the Golden Gate Bridge and put a man on the moon using nothing more than log tables.
Any one person can remember the gist of the scientific method and write it down on a page. To write down a quality logarithm table you would need 500 pages.
Real life quantum physicist here. When you say you want the uncertainty principle to be bigger, what you are really saying is you want Planck’s constant to be a bigger number. This has much bigger consequences than you might expect, because if nothing else about the universe changes (for example Coulomb’s constant) then the energy levels of atomic transitions all get out of whack, you break chemistry and chemical bonding, and there is no such thing as a basketball because there are no such thing as rubber molecules.
