Episode notes
Gargantuan Search Space
- The materials search space is astronomically large due to many element combinations and operating conditions.
- Combining ~60 usable elements into 5-element materials yields thousands of unique selections before crystal structure is considered.
Breakthroughs Often Came By Accident
- Many major materials were discovered accidentally through unusual processing or simple chance.
- Examples include Teflon, lithium cobalt oxide, and nickel-titanium shape memory alloys found via serendipity.
Limits Of First-Principles Methods
- Ab initio computational chemistry can predict material properties from quantum mechanics but is computationally expensive.
- Solving Schrödinger's equation exactly for large systems is infeasible, motivating approximations like DFT.
