5 words that influence your live without letting you know it

I know. Mark Twain said:"Don't use a five-dollar word when a fifty-cent word will do." I tend to use some of these words, because I love them. And they influence everybodys life. How?

Serendipity
...is when you find something you were not looking for. It is nearly Zen, but don't we all find most of the things when we don't look for them? Interestingly the act of finding is called searching as long as it is not successful.

Coandă effect
...is defined as the tendency of a fluid to be attracted to a nearby surface. Just think of your tea or coffee running down the teapot or of milk you try to pour...  Now the thing has a name and now you can blame it. But you should also know, that there are some real world applications. So when you blame the effect, always be thankful when you see an aeroplane. Especially when you see it from the inside.

Mnemonics
I cannot remember what this word was all about. There was this rhyme which helped me remembering what that word means. I better look it up in the Wikipedia.

Onomatopoeia
...is a word that sounds or describes the thing it stands for. It is simple. When we are small, people point at pigs and say oink. I love the german expression "Lautmalerei", which literally means painting with sounds. So simple.

Simplicity
...is when you know the words above and you can use them if you have to. Often the 5 Dollar word makes a good shortcut or hints that you will need to know how to solve differential equations, but if you really have to say something, take out your purse open it and use these rusty 50 cents...
