When I started working as a researcher I was fascinated by the question of how to make machines do things a bit more like we, humans, do. During my studies I learned how computers work, but I did not know how our minds work. So, I started reading about the human brain and how all the neurons in the brain are connected and work together so that we can speak, type, see, taste, walk, smile, and so on. At the moment science and technology has reached the level where we can build systems that imitate our brain very well. These are called Artificial Neural Networks and for me at the moment the most interesting thing I have learned (and still learn about it every day) is how to write programs for artificial neural networks.
Did you know that you can download Wikipedia? All of it! Every word! I thought that was amazing the first time I learned how to do it.
Wikipedia is probably the largest centralised repository of information about everything that we know about. By downloading it, I can teach computers about a huge range of subjects depending on what I need the computer to do. This is probably the most interesting thing I studied and learned about in the course of my PhD.
On one occasion I got the computer to study some historical stuff on a different collection (I think it was a series of books) and then asked it to tell me about Hitler. The computer replied with… well… let’s just say it was a rude word.
