In a similar way we can exclaim: \"If there would be no nonlinearity than what physics would that be'?\". Really, the most interesting and exciting effects are described by non- linear equations, and vanish in the linear approximation. For example, the general theory of relativity by A.Einstein comes to mind first - one of the most beautiful physical theories, which is in fact essentially nonlinear. Next, the phase transitions crystal liquid and liquid gas are due to the anhar- monicity of inter-particle interactions, to dissociation and infinite motion. Similarly, transitions into the superconducting state or the superftuid would be impossible with purely harmonic interaction potentials. Another bril- liant achievement in nonlinear physics was the construction of a laser and the subsequent development of nonlinear optics. The latter describes the in- teraction of the matter with light of super-high intensity, when multi-quanta intra-molecular transitions become essential. Last, we should note here the very beautiful mathematical theory the theory of catastrophes. Its subject is the study of invariant general properties of multi-dimensional surfaces in the vicinity of bifurcation points with respect to continuous transformations.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45283244507287,"sku":"9781461354949","price":7345.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781461354949.webp?v=1769304470","url":"https:\/\/atlanticbooks.com\/products\/vibrational-rotational-excitations-in-nonlinear-molecular-systems-9781461354949","provider":"Atlantic Books","version":"1.0","type":"link"}
