John : Miuson is the person in this link.   https://chihaukam.blogspot.com/2024/09/httpschihaukam_10.html?m=1 . Me: Ok. . ___ Kelvin : John is an example.  He's " surveillanced " by the satellite.  It's educational.  Look at this camera.  It hack the satellite of America.  Through the camera,  do you see John is riding bicycles?   Mr. Lee (a legislative personnels of Hong Kong): Yes, but, it's nothing special.  Kelvin : Nothing special ? You mother fucker.  I surveillance John for your own sake not for the God's sake. I ask you to be alert of the details.  You doze off. John didn't wear the helmet while riding the bicycles.  Tomorrow,  you bring this video to see your colleagues and say to them,  "we must legislate that people riding bicycle...

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.
