Are research papers useful? How should I write them and when?
What do you think of research in engineering? Isn't it better to work in a company that specializes in a certain field and knows it in and out and come up with something revolutionary instead of working at a university where everything is rather theoretical?
About 20 years ago, I heard about holographic storage. What happened with this kind of technology that it didn't go forward?
Why do DVDs need to spin these days? Why not just scan top to bottom directly into memory? Are scanning optics not good enough for that?
How does DVD-RW work? Never understood that one.
Follow-up question to storing information: Are there at present optical end-to-end computers that do not have "storage" but use working memory with an optical processing unit? And would it be easier or harder to have a multivalued "not binary" optical computer than an electronic computer?
