The world is blurry to babies when they’re born, and their vision doesn’t get super-sharp until they’re around 1-year-old.
When your baby is born, they see you and the world around them with fuzzy eyes. They focus better on objects that are up to 10 inches away from their face. This is the right distance for your baby to observe your face while you are holding or nursing them.
At around 3 months, your baby’s eyes can follow things around, so, if you wave a colorful toy near their eyes, they will track the movement.
By the age of 12 months, babies see things very clearly, both near and far. They can even quickly focus on fast-moving objects.
"Car on the right has the right-of-way" is true in the US as well - look it up - but the importation of a culture with no rules has badly eroded the observance of this standard.

A gallon is a part of a binary volume measurement system. It is very efficient (ask your computer, which spends way too much time converting to base-10). Volume is also correlated with the weight of water on Earth, "A pint (1/8 gallon [volume]) is a pound (16 ounces [force]) all the world round".
The French had a chance to make the Metric system similarly grounded in the world we live in, but they hated the English I guess so they decided to go with a less useful, arbitrary standard instead.
