ABSTRACT
In the two decades since the first publication of Are There Really Neutrinos? (Franklin, 2001), the field of neutrino physics has continued to grow 1 and the answer to the question posed by the title is an even more resounding “Yes!” Many of the themes presented, such as “How much?,” “Whose?,” “Do they oscillate?” and “How many?,” are still active areas of investigation and some dramatic progress has been made in addressing these questions.
