How not to be fooled in physics

Particle physicists and astrophysicists employ a variety of tools to avoid erroneous results. In the 1990s, an experiment conducted in Los Alamos, about 35 miles northwest of the capital of New Mexico, appeared to find something odd. Scientists designed the Liquid Scintillator Neutrino Detector experiment at the US Department of Energy's Los Alamos National Laboratory to count neutrinos, ghostly particles that come in three types and rarely interact with other matter. LSND was looking for eviden...
