In discussing listening to the live broadcast of the Nobel physics prize ceremony in Stockholm
[Sheldon] "Wednesday morning, the Nobel Prize winners are going to be announced in Sweden, and we'll hear it as it's happening." [John Sturgis] "Well, 2.8 milliseconds later." [Sheldon] "Sure, because of the propagation."
It's about 8,000 km from east Texas to Stockholm, and at 300,000 km/s, the propagation time would be 27 milliseconds, not 2.8 milliseconds. So a professional physicist and the child-genius physicists were out by an order of magnitude as, presumably, were the show's scientific advisers. In any event, shameful stuff. Sheldon would be inconsolable at such a mistake.
nb. propagation delays are actually rather longer than that with short wave radio due to the "bouncing" of the signals off the ionosphere necessary for receiving such long distance reception due to the Earth's curvature.

When Sheldon is listening to the radio to ear who won the Nobel prize the man on the radio starts out but saying good morning. Even though it was 5 am in Texas Sweden is 7 hours ahead so it would have been noon in Sweden.
The news references Billy Idol's accident that took place in February. The Nobel Prize in physics 1990 was announced October 17, so the episode takes place in October.
