Eureka

Invincible - S1-E5

Factual error: Henry Deacon says people only use 10% of their brain at any one time. That's complete garbage - at times we may use quite a small part of our brains, other times the whole brain lights up with activity. The "10%" myth has absolutely no basis in fact - no-one even seems to know where this figure came from! Given the intelligence of Eureka's residents, Henry (and indeed others in the room) would know this.

Phased and Confused - S3-E6

Factual error: Zane used ULF (Ultra Low Frequency) to communicate with Henry and notes he can "only send numbers." This is a reference to extremely low bandwidth of maximum 300 Hz transmission. However, later Henry magically creates an upgrade that allows voice communication - not possible with ULF. Also, no way Sheriff's old radio would pick up ULF band communications in the first place.

Phased and Confused - S3-E6

Other mistake: Captain Eureka losing his finger makes absolutely no sense. He doesn't cry out in pain, there's no blood, and where the finger ended up is completely illogical. The finger didn't just sever on its own; it's shown that severing only occurs when passing through objects. Captain Eureka goes through a wall that is a good fifteen feet away from where the finger is discovered, and it is implausible to think it could have rolled there on its own.

Just Another Day... - S5-E13

Trivia: In the final scene, as Jack and Zoe are heading out of Eureka, they pass their younger selves heading into Eureka. This scene is from the pilot episode where Zoe sees another version of her and her dad. However, in the pilot episode, the other (older) Jack and Zoe are in Jack's original car, not his Jeep, and other Zoe waves at them. I would call this a mistake, but I'm listing it as trivia because I know someone would say "after they came back from 1947, things changed so this changed too."
