Neural Networks are all over the place, you can see them in fields like Robotics in Self-Driving-Cars, in Medical assistance with Watson and many others applications. When people talk about it sounds cryptic and really hard. But here's how you can create one yourself.
Now we are going to be creating our owl personal Perceptron, be creative with what you would do with him. In this example we are going to use it as a Logic AND Gate
