節錄幾點
The difference boils to Einstein's = 2.
Let me just emphasize that the energy can't be calculated from masses of the electrons.
One could say that when a battery is being discharged, its electrons are moving to places that are closer to the nuclei, perhaps other nuclei, in average and the modified interaction energy affects the amount of energy=mass stored in the electromagnetic field.
Yes, the change of the mass is pretty much negligible and can't be measured by current scales.
基本上跟E=mc^2是有相關的沒錯
但這裡的質量變化並不直接是電池減少或增加的質量
再來就是電池充放前後重量的確會有變化
但難以測量出來
幾乎是可完全忽略的
