What is MOON?

MOre than ONe time I find myself using a new computer when I want to refer to my previous work which was done on the old one and the old computer is long gone.

MOre than ONe time I let some random (good) thoughts slip my mind because I was too lazy to jot them down earlier and then it takes forever to recall.

MOON, according to Wikipedia, has a lower surface gravity than Earth. When I feel pressured by all the troubles on Earth, I will feel less pressured on MOON due to the lack of gravity.

It is my greatest pleasure if any of my posts can help to reduce your burden or to bring you a bit of joy. Welcome again, you brave space traveller.

Let me start with the most straight foward equation $1 + 1 = 2$, which is known by many people since childhood. Even for people who are extremely scared of math, it is probably an equation that they will feel comfortable with. This equation holds true in almost all cases, though I am tempted to argue if you hand me one spoonful of peanut butter and another spoonful of peanut butter, both will disappear and end up in my tummy.

$1 + 1 = 0$ is a slightly tricky case. I was not careful with my notation, but for anyone who is acquainted with modulo arithmetic, a possible answer could be: yes it is true for modulo operation, in this specific case: modulo 2. Another more concrete example would be, suppose I go north 1km and then go south 1km, I end up at the starting position.

I had a really hard time trying to come up with a reasonable math justification for $1 + 1 = 1$, however it is fairly easy to think about a real-life example. If I combine two seperated heaps of sand together, I will end up having only one heap of sand. An interesting paradox related to heaps of sand is Sorites paradox.
