I really don t think that there is an ether either it was a joke that you were supposed to get That Robert Boyle actually thought that mass was not conserved in gas expansion and you can say that even easier when you have gasses coming from electrochemical sources This ether is what most scientist believed in You can say that mass is not conserved even easier if you are detecting the gas with your nose And you were also supposed to get the joke about the irish current That people ca nt define Irish because the english school system defined the word anglo irish and the english school system also defined the word electron and current It says in basic electricity NAVPERS that the total force that will KILL YOU is not the voltage but the CURRENT So the total EMF is the CURRENT and Farday said that the decay in the battery is propotional to the VOLTAGE READING So the total emf is the current and the loss of power is from the voltage and if you do nt believe me get a low voltage source and put it so it has lots of current and go kill yourself Those were two jokes that you did pick up Laugh haha funny
