Corrected entry: Assuming he had smooth skin, Data has chest hair visible in a couple of shots.
Corrected entry: In the very beginning shots of the Enterprise, the nacelles are not lit even though the ship is moving.
Correction: Picard clearly states in his log entry "Because engineering is involved in preventative maintenance of our dilithium crystals we are presently travelling on impulse power" the impulse engines are located at the stern of the saucer section.
Corrected entry: When the away team goes down to the planet, the oily blob blocks their path, like a moving moat, and Riker gets sucked into that. But later, the blob returns to covering the shuttle craft like it did before they arrived. But Riker is still inside it, he is released only later. So the moat is temporarily gone. Where is he supposed to be during the time that the black blob covers the shuttle?
Correction: The material and properties that comprise Armus (the oily blob) are unknown - since the tricorders cannot scan it. So we can only extrapolate from what we see and hear. When Riker is absorbed by the entity, he is essentially made part of the oily blob. in other words, he's liquefied. So Riker is still a part of Armus when it envelops the shuttle, he just doesn't have his physical form.
Corrected entry: When Armus engulfs Riker and then covers the shuttle, shouldn't there be a bulge to show the first officer's position?
Correction: We do not know the exact nature of Armus or his abilities, so we cannot say for sure if such a bulge should appear.
Corrected entry: In the episode "Skin of Evil", right after Commander Riker gets pulled into the sludge type black substance watch the left side of the screen. When the away team looks into it after Riker's face comes out of the sludge you will see something plop into the goo, that was Geordi's phaser falling out of his holster when he leaned over the pool of goo.
Correction: Not a mistake, as it is possible to lose things like this in real life. The mistake is, however, that the phaser reappears later, which is already listed on this site.
Corrected entry: When Riker is dragged into the pool of goo, his head reappears for just a moment, then is pulled back into the pool. Note that his mouth is open and fills with goo, but his mouth is above the surface. Obviously this is a mask that is pulled under.
Correction: The pool of goo is a living, shape shifting entity called Armus. If Armus wanted to only partially fill Riker's mouth with some of himself, it surely would have been in his power.
Corrected entry: When starting the warp-core the matter / antimatter is injected in the ratio 25:1. Four episodes earlier (S01-18, Coming of Age) Wesley solves the trick question at the Starfleet entrance exam with the only solution : The ratio has to be 1:1. (00:05:05)
Correction: Is this the proper ratio for a Galaxy class or a generic warp core? 1701-D is Starfleet's newest, most advanced vessel. It's possible that her core uses a different procedure for start up. Also, academies historically use older equipment for training purposes, since the state of the art is "on the front lines", making it even more likely that procedures on Enterprise are different from those in other vessels.
Corrected entry: Geordi's phaser falls out when the away team moves to help Riker and gets sand on it. After Picard beams down it's back in Geordi's holster, clean and shiny.
Correction: It was several minutes before Picard beamed down, more than enough time for Geordi to pick up his phaser and dust it off.
Correction: It is well established in multiple episodes that Data has body hair. He was created to look as human as possible.
