4 Days Out - S2-E9
Corrected entry: When Walt is building the battery and explains how it works to Jesse, he says that the cathode is the positive terminal. The cathode is always the negative electrode and the anode is always the positive electrode. Walt is a chemistry teacher who would know the difference. (00:37:15 - 00:38:30)
Correction: "Cathode" can be negative or positive (http://en.wikipedia.org/wiki/Cathode).
Correction: Cathode polarity with respect to the anode can be positive or negative depending on how the device is being operated. The battery is operated as a provider, so + = anode / - = cathode.
Correction: When Walt first sees his PET/CT, he is looking at a reflection of the monitor, not the actual monitor. So, it would be normal for the image to be reversed.
