Resonance Resonance In mechanical systems, resonance is a phenomenon that occurs when the frequency at which a force is periodically applied is equal or nearly equal to one of the natural frequencies of the system on which it acts. This causes the system to oscillate with larger amplitude than when the force is applied at other frequencies. Frequencies at which the response amplitude is a relative maximum are known as resonant frequencies or resonance frequencies of the system. Near resonant frequencies, small periodic forces have the ability to produce large amplitude oscillations, due to the storage of vibrational energy. In other
Problem of why there is anything at all may necessarily exist. Particles can emerge from underlying quantum fields under the effects of quantum physics and possibly under other physical laws that may have existed at the start of the Big Bang. Problem of why there is anything at all The question "Why is there anything at all?", or, "Why is there something rather than nothing?" has been raised or commented on by philosophers including Gottfried Wilhelm Leibniz, Martin Heidegger − who called it the fundamental question of metaphysics − and Ludwig Wittgenstein. The question is general, rather than concerning the existence of anything specific such as the universe
