The Beautiful Day in the Neighborhood - S5-E4
Factual error: Near the end, the gang is using Luminol to check for blood on neighbourhood signs. Luminol won't work in broad daylight, they should have used a blue light filtering lens to enhance its visibility.
Factual error: When Sam and Dean show up at the crime scene to investigate, they are stopped by a woman wearing digital Army ACU's. She introduces herself as Sergeant Miranda Bates, even though she has rank insignia on her cover and her chest that identifies her as a PFC (private first class). (00:14:05)
Noisy Edge - S1-E12
Factual error: In the beginning of the episode, Charlie is stating that "there is always a solution" and "if there's any limitation it's got to be in the mathematician, not the math". Unfortunately, according to Kurt Godel's incompleteness theorems, this is not true. Simply put, there are mathematical problems that cannot be proven/solved.
Factual error: The train car in which Elle and the other passengers are held hostage is supposed to be an Amtrak type long distance railroad car traveling from El Paso to Dallas, yet on the inside of the car we can see a large poster showing the Washington, DC Metro system map.
I Married a Mind Reader - S1-E11
Factual error: A nitpicking mistake, but on the set of "I Married a Mind Reader", the front door is a modern steel design. Back in the 60's, front doors were almost always wood (steel doors weren't available until the 1970's or 80's), and the window design would have been larger on a 1960's fan-window wooden door.
Factual error: When she's giving the historical tour, Sarah talks about how the Puritans who settled in Point Pleasant faced hardships during their first winter there. But the first village at Point Pleasant was built in 1817, a century and a half after Puritans ceased to exist as a distinct group.
Factual error: Jonah tells Richard that Saturn has a "rogue moon" in a retrograde orbit that travels "at four times the speed" of Saturn's other moons. The graphic on Jonah's computer shows that the moon in question is Phoebe, which does indeed orbit in the opposite direction from other Saturnian moons. And the graphic correctly shows Phoebe's orbit as being much further from the planet than the other moons. However, as a direct consequence of its greater orbital radius, Phoebe is actually among Saturn's *slowest* moons. It has a longer orbital period (or "month") and a slower orbital velocity than all the Saturnian moons with smaller orbital radii, of which there are twenty.
Factual error: Haloclines are referred to throughout, and depicted occasionally as some sort of underwater tornadoes. Haloclines are in fact just salinity gradients, and look nothing like they do on the show.
Episode One - S2-E1
Factual error: During this episode, Vincent is remanded to prison for suspected murder. At one scene he is seen working on the wing. Remand prisoners are not expected or allowed to carry out work duties in British Prisons.
Factual error: When Rich and Laura are searching for drug information from the 1960s, they visit the US Patent Office website; under the heading "SSRIs", is displayed "Selecttive Serotonin Reuptake Inhibitors" - with the double-t spelling error. (00:15:25)
