Faça um pêndulo leve com um pequeno ímã em sua extremidade. Um eletroímã adjacente conectado a uma fonte de corrente alternada de frequência muito superior à frequência natural do pêndulo pode levar a oscilações não-amortecidas com várias amplitudes. Estude e explique o fenômeno.
To get the correct answer one must ask the correct question. In the field of Quantum Gravity the question has been how do we quantize General Relativity or derive a quantum theory which becomes General Relativity at low energies. Observing that Quantum Field Theory was the result of making Quantum Mechanics into a relativistic theory, I asked myself why not make QFT obey the principles of GR? I answered this question with a model I call Relativization. In a series of three papers I presented an answer to this alternative question which gives finite results for everything from black holes to particle physics.
