John: Have a look https://wodewangzhishime.blogspot.com/2021/10/httpswodewangzhishime_52.html . If the bishop eucharistize,  what should the followers do? Me: They should eucharistize too. John: Excellent. . Daniel (an America's hackers): Look at this camera. It hack the satellite of America. Y ou should see that John  is riding bicycles. John doesn't wear helmet. . Tomorrow, you show this video to your colleagues and you say to them "We must legislate that people riding bicycles must wear helmet".  Mr. Cheung (a legislative councilor of Hong Kong): I will do that. However, Bradley and Charles murder a lots of pagans. We should murder the pagans too. . Daniel looks at the sky and laugh in a manner of self-esteem, . Daniel: Bradley and Charles are terrorists. Of course, they murder the pagans. Mr. Cheung: Th...

Me: Ceremic resistor has 2 layers. . Valance layer and conductive layer. John: Valance layer can't conduct because it has no pi bonding. .You can also say that it has no delocalize electrons. 1)  The thicker the valance layer, the higher the resistance. 2) The thiner the valance layer, the lower the resistance.

John: The 2 pictures above are FM modulation. Which one is correct. Me: Logically, the 2nd picture is correct. John (shaking head): No,. The 2nd picture is incorrect. Me: The 1st picture is correct. John: Yes,. . In the 1st picture, there're 2 circuit. They're circuit A and circuit B. In circuit A, the left-side branch is high frequency, 100 Mhz. However, the right-side  branch is low frequency, 80 Mhz. . John: As a result, circuit B is induced a electrical current of low frequency which is just 80 Mhz.
