The 2007 Nobel prize in Physics has been awarded to Albert Fert and Peter Grünberg for independently discovering Giant Magnetoresistance in 1988. Their work had a tremendous impact on the computer industry as it revolutionized the way we could store and retrieve information on hard disks. It was the first major application of nanotechnology and allowed hard disks to shrink from the size of a large washing machine to the device that fits in an mp3 player

There is a lot of positive feedback about the Dynamo paper but I noticed that something I wrote in introducing the paper is being misunderstood. This was my fault, I wrote it too strongly.

Let me first tell you the why and then I will explain the what. By using classes in Javascript, you will notice a couple immediate benefits: Custom classes make your code more reusable. If many of your applications use a similar functionality, you can define a class to help and facilitate that functionality. Now you can just use your new class in multiple projects to provide the common functionality. For example, let’s say you create a custom accordion effect.
