Now, I talked to Paul afterwards -- I wanted to check to find out how he'd calculated this, and get the sources and so forth -- and he also gave me a paper that he had written on this.
Saya berbicara pada Paul setelah ceramahnya. Saya ingin tahu bagaimana dia menghitungnya, dari mana sumbernya, dan hal lainnya. Lalu dia memberi saya makalah di mana dia menulis hal ini.
