Murphy's Law

"Anything that can go wrong, will go wrong".

From an inventor's viewpoint, this is ultimately an argument for keeping things simple and focused on a single task. The simpler an invention is, the less scenarios need to be considered and tested.

Another way to understand it is as though you are living in the future looking back at a problem that occurred:

"If something went wrong with your invention, it's because you didn't do anything to prevent that scenario from happening".

Examples of things you could have prevented but didn't, and thus went wrong:
- The electrical cables burned the house down because the load was too hot. This could have been prevented by adding a fuse, but you didn't.
- The water heater exploded because it didn't have a pressure release valve, which it could have had, but didn't.
- The door fell off the plane when it went upside down because the hinge pin didn't have a lock, which it could have had, but didn't.
- The Earth shifted and caused cracks in the clay pipes under the house, which could have been prevented if flexible piping was used, but it wasn't.

Again, ultimately this is a reminder to keep your invention as simple as possible. It's often tempting to keep throwing new features into it, to make it appeal to a larger audience or solve more problems, but every new feature creates new, untested possible outcomes which can be hard to predict. Hard to predict that is, until they've happened, which they will.
Inventor 1: I created a lightswitch! It has 2 possible states: on or off. I'm aware all of the scenarios that could exist!

Critic: Great, except I see you used iron on the connector pins. Did you account for the corrosive reaction if copper wire is used against the iron? Murphy's Law dictates that it will happen at some point, because it could.

Nermal’s Law

Allows you to find the answer to any question by simply dividing the correct answer with your answer. The number received is Nerm’s Inconstant. You then use the Nerm’s Inconstant to multiply your answer to find the correct answer.
Oh you can’t find the answer? Use Nermal’s Law!”

Sister-in-law

The woman who doesn’t come to your wedding because she has more important things to do, yet expects you to pay for half of her wedding and will upend the entire family unless she gets her way. She is usually supported by your mother-in-law who somehow always takes her side in every possible argument.
Your sister-in-law thinks she’s entitled to you paying for half her wedding yet she has the audacity to not even come to your wedding.
