It may be forgivable to use dynamic mass in an article written for laymen and using a simple model of the atom, but I feel I should mention that the concept of objects changing mass depending on the reference frame is a very dangerous one because substituting the dynamic mass for the mass in a classical formula does not always lead to correct results. The concept of dynamic mass is motivated by wanting to continue to write the previously known…

"If someone tries to sell you non-relativistic gold you are being had!" This is mostly a concern for theorists who prefer to go as far as possible with non-relativistic theories. This relativistic shift also has large implications for the bonding of gold nanostructures. The relativistic correction shifts the energy of the core electrons and they hybridize - giving the Au - Au bonds directionality. Small gold clusters can thus take on planar, cage, and tubular structures - completely contrary to…
