The Core of the Sun enhancing her knowledge of chili peppers by extending an invitation to his farm. There, she sampled and grew an assortment of peppers. Working with chili peppers allowed Sinisalo to understand factors such as the Scoville rating which is determined by capsaicinoids. The Scoville scale measures the spiciness (heat) of the pepper. One can explore the Scoville ratings, health benefits, and growing techniques of peppers on Kilpinen's website In the Core of the Sun's Afterword, Sinisalo describes the Transcendental Capsaicinophilic Society as “ a real, though somewhat tongue-in-cheek, group that can be found on the Internet.” A quick Google search reveals
An Experimental Enquiry Concerning the Source of the Heat which is Excited by Friction heats of the material machined away and that remaining were the same. Rumford argued that the seemingly indefinite generation of heat was incompatible with the caloric theory. He contended that the only thing communicated to the barrel was motion. Rumford made no attempt to further quantify the heat generated or to measure the mechanical equivalent of heat. Most established scientists, such as William Henry, as well as Thomas Thomson, believed that there was enough uncertainty in the caloric theory to allow its adaptation to account for the new results. It had certainly proved robust and adaptable up to that time.
