Essentially, in this paper it's a light wave were the spatial and temporal dimensions are not easily separable. What the authors seem to do here is essentially do a time dependent spatial correlation of a light pulse, which then exhibits
"unintuitive" properties. The paper reads a little bit, like several similar papers in the field, where something relatively trivial is packed into a nice sounding story. That said I have not read the details yet and there might be something more profound.
Concur. I found Gradle to be to far removed from the truth so to speak. I like Maven's declarative xml and its promulgation of the build life-cycle. This makes a complex build easier to maintain in the long run imo.
Why is making connections to prior experience, turning knowledge into wisdom, and gaining a unique perspective on truth. It's a completely different game than stacking facts on top of each other. Why is creative, and what is created can never be taken away; how is useless once obsolete.
