Dynamics Quotes - page 5
Ironically, conventional quantum mechanics itself involves a vast expansion of physical reality, which may be enough to avoid Einstein Insanity. The equations of quantum dynamics allow physicists to predict the future values of the wave function, given its present value. According to the Schrödinger equation, the wave function evolves in a completely predictable way. But in practice we never have access to the full wave function, either at present or in the future, so this "predictability” is unattainable. If the wave function provides the ultimate description of reality - a controversial issue!

By just taking a breath you're moving into attention a little bit and so you get much less caught up in reactivity. A practical application of this in your life is, never say anything before you've taken one breath. It's a very simple practice--changes the dynamics of conversation with other people completely.

There is no over-arching theory of complexity that allows us to ignore the contingent aspects of complex systems. If something really is complex, it cannot by adequately described by means of a simple theory. Engaging with complexity entails engaging with specific complex systems. Despite this we can, at a very basic level, make general remarks concerning the conditions for complex behaviour and the dynamics of complex systems. Furthermore, I suggest that complex systems can be modelled.

Hindu society has grown and shaped itself in the vision of Vyasa and Valmiki, Manu and Yajnavalkya, Narada and Vasistha, and a hundred other exponents of Sanãtana Dharma in all its dimensions and dynamics. Hindu society has been inspired through the ages by such mighty šãtras as the Vedas, the Upanishads, the Gita, the Jainagama, the Tripitaka, the various Yogasastras, the Vani of Siddhas and Sants, and the devotional outpourings of Alvars and Nayanars. Hindu society has been defended, during its days of distress, by such high-souled heroes as Chandragupta, Skandagupta, Vikramaditya, Yasodharman, Bapa Rawal, Jayapala, Bhojadeva, Prithiviraj, Prataparudra, Vir Pandya, Harihara and Rana Sanga. Hindu society has fought a long-drawn-out struggle for freedom against Islamic invaders under the leadership of such veterans as Maharana Pratap, Shivaji, Maharaja Surajmal, Banda Bairagi, Lokmanya Tilak, Veer Savarkar, Mahatma Gandhi, and Sardar Patel.

Dream is personalized myth, myth is depersonalized dream; both myth and dream are symbolic in the same general way of the dynamics of the psyche. But in the dream the forms are quirked by the peculiar troubles of the dreamer, whereas in myth the problem and solutions shown are directly valid for all mankind.
Joseph Campbell
It's a battle between record company, between producer and between mastering engineer. Because the louder you make your record in a digital process, the more dynamics are squished out of it. Nobody knows exactly what happens, but the dynamics in the performance disappear, and everything is at the same volume.
Geddy Lee
It has become ever clearer that underdevelopment is the end result of a process. Therefore, it must be studied from a historical perspective, that is, in relationship to the development and expansion of the great capitalist countries. The underdevelopment of the poor countries, as an overall social fact, appears in its true light: as the historical by-product of the development of other countries. The dynamics of the capitalist economy lead to the establishment of a center and a periphery, simultaneously generating progress and growing wealth for the few and social imbalances, political tensions, and poverty for the many.

... It was (in part) Gross's excessive enthusiasm for string theory in the mid-80s that drove me (as an impressionable grad student at Princeton) away from theoretical physics (and into astronomy). String theory may have been a beautiful idea, but it made no predictions that could be tested experimentally in the then-foreseeable future. That's not science.
A quarter century later and the theoretical physics community has yet to wake up and realize that there is new physics right under their noses – just not the new physics they've been expecting (GUTs, strings, membranes, etc.). Galaxy dynamics are consistent with a single, universal force law, but this unexpected behavior has largely been ignored because it doesn't fit with particle theorists' dreams of super symmetric dark matter particles. That we do not understand the observed behavior makes it more interesting than the "expected” (but unobserved) new physics: who ordered this?

The current cosmological paradigm, the cold dark matter model with a cosmological constant, requires that the mass-energy of the Universe be dominated by invisible components: dark matter and dark energy. An alternative to these dark components is that the law of gravity be modified on the relevant scales. A test of these ideas is provided by the baryonic Tully-Fisher relation (BTFR), an empirical relation between the observed mass of a galaxy and its rotation velocity. Here, I report a test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals. The data fall precisely where predicted a priori by the modified Newtonian dynamics.

The concordance model of cosmology, ΛCDM, provides a satisfactory description of the evolution of the universe and the growth of large scale structure. Despite considerable effort, this model does not at present provide a satisfactory description of small scale structure and the dynamics of bound objects like individual galaxies. In contrast, MOND provides a unique and predictively successful description of galaxy dynamics, but is mute on the subject of cosmology. ... it is far from obvious that the mass spectrum of galaxy clusters or the power spectrum of galaxies can be explained in MOND, two things that ΛCDM does well. Critical outstanding issues are the development of an acceptable relativistic parent theory for MOND, and the reality of the non-baryonic dark matter of ΛCDM. Do suitable dark matter particles exist, or are they a modern aether?

The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.
