47:38>> Yeah. >> Uh also in 1931, you're going to notice a change of pace here. If you're looking at our timeline at the bottom, you can see there's a lot of dots coming up. Quantum theory of the chemical bond. Yes, this is Lionus Powing, the infamous Lionus Powang at Caltech, the newly established Caltech. He used quantum mechanics to talk about molecules. Everyone was worried about individual atoms. What he said was, can I use quantum mechanics to talk about molecules and the chemical bond? He introduced orbital hybridization and resonance. This is something that we still use today and really provided the mathematical and physical foundation for modern chemistry.
