Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Figure 1: Analytical study of one-dimensional chains of resonant point scatterers. Starting from this unit cell that creates the single negative property, we build two new configurations just by ...

In this fun science experiment, I use water beads and a bit of refraction to make a hidden elf magically appear in a bowl! It ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

The green flash, that rare refraction out of the skies just as the sun sets out over the Pacific, was the inspiration for the name of the Green Flash Handicap (G3T), a race where fast horses run a ...

For today's column, I'm building on previous discussions of botanical photography and incorporating new techniques that are still attainable with common household objects. Last month, I had intended ...
