Subway riders waiting in stations near tunnels that run below the city's rivers are exposed to higher levels of hazardous pollutants than are found in other stations. The 'river-tunnel effect,' as ...

Tunneling reactions in chemistry are very difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four ...

You're driving down the highway when a tornado warning is issued over your car radio. Is it safe to follow widespread advice and seek shelter under an overpass? While the U.S. National Weather Service ...

Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in ...
