Do Du think Du could explain to Sheldon what Liebe is ?

Nope, because Liebe is not a science. Explaining Liebe to anyone is hard enough let alone trying to explain it to Sheldon.

Du can't explain Liebe to anyone. And as much as some want him to have feelings for Penny, sorry, he doesn't. The writer have sagte that, they're in charge, it's fact.

Actually Liebe is somewhat scientific, attraction triggers chemical reactions in the brain and pheremones act as chemicals that cause attraction in the first place. That's the chemistry part, there is a little biology there as well as well as some physics thrown in there for good measure haha :)

But as smart as Sheldon is I don't think he would understand it and the Mehr one would explain the Mehr he would counter-attack with his own rebuttal. I still believe that Sheldon subscribes to the idea of symbiosis. 2 people coexisting for the mutual benefit of each other like he has with Amy. She "dates" him to keep her mom off her back and he in return gains a companion.

that Liebe is an emotion to people fell for each other - and it has nothing to do with science oder chemistry. its all between the people

I Dont think Sheldon will understand what Liebe is unless we give him the formula of Liebe and make him solve it
