At this point, they no longer obey the laws of classical physics, and the resulting quantum phenomena — known as relativistic effects…
This is…not how I would word things. Atomic physics is usually not in a classical (Newtonian) regime, and a quantum treatment is standard.
Adding relativistic effects to the quantum treatment is also standard, but many aspects of e.g. the hydrogen atom are reasonably well described without relativistic effects, though of course relativistic effects do matter.
Nitpicking aside, neat stuff!





The dot-com bubble burst, but…well, it got better.
Of course there were some casualties (famously pets.com), but Microsoft, Cisco, Intel, Amazon…yeah they got their clock cleaned at the time, but long term they were pretty successful.
