This chapter describes the dynamics of a modulated oscillator for resonant and nonresonant modulation. Two types of resonant modulation are considered: additive, with frequency close to the ... More


The “What” and “Why” Questions

Massimiliano Di Ventra

in The Scientific Method: Reflections from a Practitioner

Published in print:
2018
Published Online:
June 2018
ISBN:
9780198825623
eISBN:
9780191864605
Item type:
chapter
Publisher:
Oxford University Press
DOI:

Subject:
Physics, History of Physics, Theoretical, Computational, and Statistical Physics

This chapter clarifies that Science cannot address either ontological (“What”) or teleological (“Why”) questions about the natural world. Therefore, “understanding” in Science is completely different ... More

Signaling and Measurement Dependence

Valerio Scarani

in Bell Nonlocality

Published in print:
2019
Published Online:
September 2019
ISBN:
9780198788416
eISBN:

Subject:
Physics, Particle Physics / Astrophysics / Cosmology, Theoretical, Computational, and Statistical Physics

This last chapter studies the relaxation of the conditions of no-signaling and measurement independence. For signaling models, after stressing the need for fine-tuning, it is shown that the speed of ... More
