Can anyone ever truly take credit for a discovery? Every researcher stands 'on the shoulders of giants', as Sir Isaac Newton said. Scientists talk to each other and argue and hone their thoughts based on the criticisms and reactions they get. No one lives in a bubble and great things happen when a lot of smart people know each other and debate as often as possible.
But when the debates are well-known, it's difficult to assign credit and far too easy to take it away. In modern times, tearing down statues of giants and standing on the rubble happens more often than standing on their shoulders and reaching new heights. And everyone wants to stand on the rubble of Albert Einstein.
