While they’ve been around for billions of years, #neutrinos came to life in 1930 as the brainchild of Wolfgang Pauli. And though trillions of them are all around us, it wasn’t until 1970 that the first #neutrino observation occurred in a #hydrogen bubble chamber at Argonne National #Laboratory. This is the #photographic evidence. (Where do neutrinos come from? Find out here: bit.ly/1hsyFTy.) #photooftheday #science #physics #particle #nobel #nobelprize 📷 Argonne National Laboratory
