Carol thats right. From fighter jets, electric cars, lasers, and the marks it market for nitrous oxide cold brew. Jason here is joel weber on the elements. Joel what we decided to do was to cover every single element on the periodic table because it ultimately, these are all business stories. This is the story of business. Carol you took us places that were a lot of surprises for us. We think of it as developed a long time ago. And, it is such a bigger, broader thing and means a lot today. Joel and is the wrong way to think about it. If you associated with High School Chemistry class and you get anxiety. Things like helium, party city was Closing Stores because there is a helium shortage, and there are entrepreneurs trying to solve the problem. Or lithium, and you think about Battery Technology and what electric vehicles will be possible, or hydrogen. So everyone of these things, these are things we take for granted, like a computer chip and how many elements are required to make this.
