Any article that quotes Marc Cushman is automatically suspect in my book.Right. I mean, it's not like TOS consulted with the RAND corporation or something. Uh-oh, wait, the Wayback Machine is jangling: What, Wayback? They did consult with RAND? Sure it wasn't Rand, as in Yeoman Janice and her Beehive Bonnet? No? Ok, it's coming through my earpiece and hooded viewer now: look, it's The Scientific American with a subtitle: "Fifty years after the original series premiere, it's still the gold standard of scientific accuracy, even with the occasional blunder."

I believe GR consulted by post with Asimov too.
But no, those 60's writer producers didn't try to be somewhat scientifically accurate while at the same time making high quality tv.

The thing about advice, is you don't have to take it. As the article points out things did slip by the folks hired to give it. And like any piece of fiction Trek was happy to err on the side of drama.
