I think the title of the article is misleading, as we cannot see light as a wave and a particle at the same time. In fact the idea of 'see' has no real concept in quantum mechanics. We can observe, but not really see. The act of observing plays a central theme in quantum mechanics, it causes the wave function to collapse. We can measure the effect of making an observation.
However, the experiment demonstrates the steps made forward in physics and from the perspective of what has been reported, it is very interesting.
