Corrected entry: Factual errors: when we see the statue of the Egyptian statue, it is incorrectly depicted on several levels. First, Taweret was never shown as a human with an animal head, like the gods Anubis, Thoth, Horus, etc., were. She was always carved as an upright, unclothed pregnant hippopotamus. Second, even using artistic license because this is a fictional show, someone should have done some research and realize that Taweret is a goddess and as such, she would not be wearing a kilt because that was only for male gods. Also, no god or goddess would be wearing footwear of any kind but if you look close, you can see that the statue is wearing something that look like Greek or Roman sandals. The only thing that the makers of the show got right is that Taweret is carrying ankhs.
Corrected entry: Towards the end of season five, they talk about how they need to get the nuke to destroy the energy at the swan. However, according to Newton's conservation of energy, energy can neither be created nor destroyed. So blowing up this pocket of energy with a bomb is futile, as it just wouldn't work. However, this is a major plot device, and Farraday, who is a very 'intelligent' physicist, is the one to come up with this pointless idea.
Correction: We do not know what kind of energy is in the pocket, and thus we cannot know why Faraday believes detonating the bomb will neutralize it. It cannot be concluded, with certainty, that his intention is to "blow up" the pocket of energy. Perhaps he believes, for some reason, that the nuclear blast will somehow neutralize this pocket of energy, rather than destroying it. Plus, we have repeatdly seen violations of the laws of physics on the island.
Corrected entry: When Hurley and Miles drive into the construction area of the Orchid Station (1977), all the vehicles are from the 60's or 70's, but a backhoe made around 2004 is present.
Correction: Research will tell you a lot. For example: the excavator used in episode 5x13 was constructed in 1977, so it's not a mistake.

The Life and Death of Jeremy Bentham - S5-E8
Corrected entry: Locke goes to visit Walt, but in a previous episode, Walt visits Hurley and says Jeremy Benthem visited him. Locke never mentioned the name he was using.
Correction: It has been established in previous episodes that Walt "sees" things and knows things that no one else does. He could have simply seen the name Jeremy Bentham" in a dream or vision.
Correction: Who said this statue was Taweret? It's not stated in the show; it's not even certain to be of Egyptian origin.
