What theory did Polanyi pioneer in 1921?
Fibre diffraction analysis
Quantum mechanics
Relativity
Chaos theory
Answer
Fibre diffraction analysis, pioneered by Polanyi in 1921, is a technique used to determine the structure of crystalline materials. It involves directing a beam of X-rays or electrons at a sample of the material and analyzing the resulting diffraction pattern. This pattern can be used to determine the arrangement of atoms within the crystal lattice.
