BP: Time for a Change

  • Jesse R Townsley (a1)

This article proposes a solution to the problem of defining the “present” in the BP time scale as 1950. Discouraging the use of “Before Present,” as well as “Before Physics,” and promoting Radiocarbon’s official definition of “BP is understood as a symbol meaning precisely ‘conventional radiocarbon years before AD 1950’” is advised.
