Default Remember "double slit" experiment?

Remember the famous double slit experiment from high school science class?
https://en.wikipedia.org/wiki/Double-slit_experiment

Check out the triple slit experiment.

Formal paper here: http://www.nature.com/articles/ncomms13987

Physicists detect exotic looped trajectories of light in three-slit experiment

Physicists have performed a variation of the famous 200-year-old double-slit experiment that, for the first time, involves "exotic looped trajectories" of photons. These photons travel forward through one slit, then loop around and travel back through another slit, and then sometimes loop around again and travel forward through a third slit.

The red path shows an exotic looped trajectory of light through a three-slit structure, which was observed for the first time in the new study. Credit: Magaña-Loaiza et al. Nature Communications

Is it time to visit the "4 slit"? (or would that be 5 slit?)

I guess you have your next experiment.

Typo, maybe? I really doubt that the state of physics was such in 1817 that they could have even conceived of this kind of experiment.

Obviously for light any and every slit will do.

The observation that the double slit created a interference pattern, and was very well explained if light traveled in wave form, was made pretty early on (early 1800s - Thomas Young).

This way before any of the quantum interpretations/implications involving single photons and the dual nature of light were conceived (early 1900s - Einstein et al).

Just further example of the uncertainty principle..,

Particle physics is like box of chocolates.

You never know what your going to get.
