A Solar Calculator, a Game Ball, and a Cheerleader's Bosom - S1-E5
Factual error: The commentary suggests that Sheldon had the correct solution to problem 1 and merely lost points on the quiz because he didn't show his work. In reality he did the first problem incorrectly. Taking the derivative of (x+2) ^2+ (y+1) ^2 = 13 with respect to x yields: 2* (x+2) +2* (y+1) * (dy/dx) = 0 which implies that: dy/dx = - (x+2) / (y+1) and at the point (0,2) this means that the slope dy/dx is actually equal to - (2/3), not 2/3. It is correct that when using the form y=mx+b at the point 0,2 reveals that 2=m*0+b, or that b=2. So the correct equation for the tangent line is y = - (2/3) x + 2, not y = (2/3) x + 2 as shown in the episode. (00:13:55)
A Solar Calculator, a Game Ball, and a Cheerleader's Bosom - S1-E5
Continuity mistake: When Connie is playing the slot machine at the end, the wheels land in a set order. She then has a chat with someone and then goes to spin again, but the wheels are in different positions than before. We see Connie through all of this, and she doesn't spin between the two instances outlined here. (00:17:30)
A Solar Calculator, a Game Ball, and a Cheerleader's Bosom - S1-E5
Factual error: In this episode we see George throwing a ball against his bedroom wall. On the wall is a picture of Axl Rose wearing shorts in the pattern of the USA flag. This photo is from the Guns N' Roses appearance at Rock In Rio 2 festival in Jan 1991. The show is set in 1989. 2 years prior to the photo the poster is made from is taken.
A Patch, a Modem, and a Zantac - S1-E6
Factual error: At the start of the episode when someone is talking at the podium, there's a a periodic table behind him on the wall. On the left of barium, 'Sc' for scandium is there instead of 'Cs' for cesium. (00:00:40)
A Patch, a Modem, and a Zantac - S1-E6
Continuity mistake: When George Jr. asks the NASA representatives if he's seen the movie Aliens, the man goes from standing up to leaning on the podium between shots. (00:01:05)
A Patch, a Modem, and a Zantac - S1-E6
Continuity mistake: At the dinner table, when Connie says, "Well, that goes without saying," George JR has a beer bottle on the table. Camera changes, and now he's holding it up in the air. (00:03:10)
A Patch, a Modem, and a Zantac - S1-E6
Continuity mistake: At the start, Sheldon has his arms crossed at the dinner table, and then the shot changes. When it does, he has a fork in his hand and a hand up by his face. Shot changes again, and he's back to having his arm folded. (00:03:21)

Continuity mistake: When Sheldon is lying on the sofa, his position changes several times. Note his shirt sleeve in relation to the edge of the cushion he is lying on. (00:12:50)
A Patch, a Modem, and a Zantac - S1-E6
Continuity mistake: When Sheldon is doing the maths for NASA, he taps the chalk on the board twice, leaving two dots. These dots disappear in subsequent shots. (00:14:50)
A Brisket, Voodoo, and Cannonball Run - S1-E7
Continuity mistake: When George Jr confronts Sr about looking for a brisket recipe, Sr has the box closed in one hand in one shot and open with 2 hands in another. (00:06:10)
A Brisket, Voodoo, and Cannonball Run - S1-E7
Continuity mistake: The root George Sr is buying is different to the one he hands the shopkeeper. Note the thickness. (00:10:15)
Cape Canaveral, Schrödinger's Cat, and Cyndi Lauper's Hair - S1-E8
Continuity mistake: When George Sr. goes to wake Sheldon up, we see Missy lying on her bed with her leg stuck out and uncovered by the duvet. When we see George closing the door, Missy's leg is now covered by the duvet. (00:05:55)
Cape Canaveral, Schrödinger's Cat, and Cyndi Lauper's Hair - S1-E8
Continuity mistake: Missy asks if she can dye her hair orange. When she does this, she has a section of hair either in front of or behind her shoulder, depending on the angle of the camera. (00:08:20)

Continuity mistake: Mary tells Missy that her hair isn't changing colour. Missy then proceeds to sulk and has her spoon in her dish. The camera changes, and now she is holding the spoon upright. (00:08:20)
Cape Canaveral, Schrödinger's Cat, and Cyndi Lauper's Hair - S1-E8
Continuity mistake: When Sheldon says that George Sr gives off a lot of heat, George's hands change position. He has 1 on top and 1 underneath the duvet in the first shot, and both on top in the second shot. (00:14:50)
