Wind of change

with 4 comments

A couple of weeks ago, Prof. Constantine Caramanis (UT-Austin) visited Stanford and gave a talk in our group meeting about robust optimization. During the talk, he had a comment (which I’m rephrasing here): “previously (ten years ago, maybe?) linear optimization is easy, and non-linear is hard; now, actually convex optimization is easy, and non-convex is hard…”

That made me again thinking about how fast the science and technology change over the last ten years, and how hard it is to keep up with current advances if you are working in an engineering/science field. In 2002-2003, I did my undergrad final research project on 3G cellular wireless networks, which was one of the hottest research topics in Vietnam at that time. However, I couldn’t imagine that just 5 years later I would be able to watch a YouTube streaming video on my 3G cell phone while driving at 70mph on highway. It’s just amazing!

On the other hand, some of the current advances will possibly die in the next few years. There are quite a lot of such examples in the past, e.g., ISDN (Integrated Services Digital Network), or ATM (Asynchronous Transfer Mode). There were times (not too long ago) that they received much attention, but now, well, you probably can only find them in a dead-tree textbook.

Of course, I really hope that these cutting-edge researches I’m seeing now won’t disappear and will be realized in the next 10 years or so. Let’s see…
