The scaling theory of localization demonstrated that the disorder-induced M-I transition was a true phase transition with a well defined critical point.
In spite of the evidence for the disorder-induced M-I transition as inferred from the transport and optical measurements, the metallic state of conjugated polymers has been a subject of controversy.
The human family is at a critical juncture. The world is moving through a great transition. This transition is economic, as the digital revolution advances and as new powers and groups emerge.
To turn Karl [Popper]'s view on its head, it is precisely the abandonment of critical discourse that marks the transition of science. Once a field has made the transition, critical discourse recurs only at moments of crisis when the bases of the field are again in jeopardy. Only when they must choose between competing theories do scientists behave like philosophers.
Essentially the Obama administration sabotaged Trump's transition to the White House. They were doing this during the transition. While Obama's talking about, "I want the smoothest transition in the history of transitions," he was sabotaging it even then.
Many transition states have a well-defined preferred geometrical requirement.
What people that are professionals in the art world - both in literature and the other arts - always try to do is to recognize the feasibility of making the transition from the particular to the general - to make the transition from the portrait of one postman - to take Van Gogh, for example, to something that is every postman. That synecdotal transition that most selfies don't make. But we who live in this world, and not simply in our private realities, understand that that's the transition our art has to make.
Well, I think by any expectation South Africa has come a tremendously long way. We've seen a society that many people thought couldn't withstand a peaceful transition to democracy without a great deal of violence, in fact, make that transition and do it in relative peace and security.
It isn't the changes that do you in, it's the transitions. Change is not the same as transition. Change is situational: the new site, the new boss, the new team roles, the new policy. Transition is the psychological process people go through to come to terms with the new situation. Change is external, transition is internal
My transition from scientist to entrepreneur? Some would say that I still haven't made that transition.
I like businesses in transition, first of all. If ever there were a business in transition, it is publishing.
Change is situational. Transition, on the other hand, is psychological. It is not those events, but rather the inner reorientation or self-redefinition that you have to go through in order to incorporate any of those changes into your life. Without a transition, a change is just a rearrangement of the furniture. Unless transition happens, the change won't work, because it doesn't 'take'.
Running in transition and scoring in transition, prevents you from setting your defense up on the other side.
Offensively and defensively, I think I probably do a lot better in guarding people in transition and shooting the ball in transition.
I'm so grateful that I had the luxury of transitioning in private. Because when you transition in the public eye, the transition becomes the story.
Our crisis is a birth. We are one living system and we have come to the limit of one phase of natural growth on a finite planet We must learn ethical evolution quickly As we seek to facilitate a gentle birth, a graceful and nonviolent transition to the next stage of our evolution, we will discover a natural pattern, a design of our birth transition, and develop a plan to cooperate with this design.
Buddhism, I think, is probably facing the single most difficult transition from one historical epoch to another, which is really the transition to modernity.
