1. Prime Number
A mathematician, a physicist, a civil engineer, and a Software Engineer are asked (after a few beers) to show that all odd numbers greater than 1 are prime.

### Enable Finder to Show or Hide Invisible Files and Folders on Mac

Some people have no clue that there are a huge range of hidden files and folders on their Mac OS X. Apple likes to keep things easy for users by hiding them. This is good for newcomers but keeping files hidden is very tedious for experienced users who is looking to tweak and fine-tune the Mac. So, how do you reveal hidden files on your Mac? Well, we can use our Terminal or third party software. I personally prefer Terminal. Ok then Open the Terminal application in your Utilities folder. At the prompt, enter or paste the following command lines one by one then press RETURN.

```     defaults write com.apple.finder AppleShowAllFiles TRUE

killall Finder
```
