Quick notes: Green kingdom, Sriracha sauce...

• Bhutan moving towards all electric vehicles: Bhutan's main export is clean electricity from hydroelectric plants, which is sold to neighboring India. But most of the revenue from those sales now goes to importing fossil fuels for transportation.  The government imposed a "green tax" on all vehicles: 20 percent on those with engines of 1.8 liters or more, 5 percent on those below.



• Is the Universe a Simulation? One possibility is that we live in a computer simulation based on the laws of mathematics — not in what we commonly take to be the real world. Very clever. But is there any way to empirically test this hypothesis? Indeed, there may be. In a recent paper, “Constraints on the Universe as a Numerical Simulation,” the physicists Silas R. Beane, Zohreh Davoudi and Martin J. Savage outline a possible method for detecting that our world is actually a computer simulation.
