Stuck on a problem?  Maybe you just need to change your thought patterns and see things in a different light.  Quite literally!

Apparently  light is not only a wave but also a particle ,  possibly,  whose behaviour can alter depending on how you chose to look at it.  Seems to me like that's exactly how us engineers tend to go about solving problems.

(hehe and just like the topic of the article,  that last sentence could be interpreted in several ways depending on how you wish to view it ;)
