I am curious and also want to clear my understanding about the nature of research which students undertake in a PhD program.
Take this product as an example.
- What is the difference between the research behind the development of this product, and a PhD research which is able to earn a degree?
- Does a 4-5 years' PhD research degree program allow developing a product like this?
- Does the student need to mask his product development as a PhD thesis by selecting a cryptic title which sounds "wise", or would he be allowed to use a plain title like "A desktop sweater knitter"?
