Do あなた think あなた could explain to Sheldon what 愛 is ?

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

あなた can't explain 愛 to anyone. And as much as some want him to have feelings for Penny, sorry, he doesn't. The writer have 発言しました that, they're in charge, it's fact.

Actually 愛 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 もっと見る one would explain the もっと見る 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 愛 is an emotion to people fell for each other - and it has nothing to do with science または chemistry. its all between the people

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