![]() ![]() The naturalness of a theory means it does not contain numbers without units (also known as dimensionless parameters) that are either much larger or much smaller than 1. ![]() For example “mirroring” of an image, changes the orientation but preserves the original image. A symmetry is a transfomation operation on a system which is invariant to the systems state or objects. In physics such simplicity is mostly achieved by finding symmetries. $beauty = simplicity + naturalness + elegance$Ī thing is simple if it can be derived from few assumptions. ).īeauty in physical theories according to the book is defined as: ![]() She investigates a phenomenon among physicists being lead by beauty and highlights the paradoxy of this approach, how widespread this way of thinking is and where it possibly leads to (Spoiler: Theory predicts particles => Build collider => No particles detected => build bigger collider => No particles detected => build event bigger collider => (.
