- Do you mean tachyon in bosonic string theory? 为何弦理论中的基态是超光子,超光子是什么意思?
- Its inputs might be calculable in string theory. 这些东西或许可以从弦论算出来。
- I'm betting my career that it's string theory. 我拿我的事业来打赌就是弦理论。”
- What do the scalar fields of string theory represent? 那麽,弦论中的纯量场代表什麽呢?
- Another hallmark of string theory is the positing of additional dimensions. 弦论另一个标志是额外的维度。
- Then physicists would have to turn to more radical postulates, such as those of string theory. 那麽物理学家就必须要转向更根本的假定了,如同弦论所做的一样。
- What is more, the holographic theory seems to provide some insight into the elusive exact equations of string theory. 弦论发明于1960年代末期,目的是要描述强交互作用。
- A natural way to overcome its limitations would be to subsume it in a quantum theory of gravity, such as string theory. 要克服这个限制的一个自然方法,就是将它纳入一个量子重力理论之中,例如弦论。
- In the pre-big bang scenario, it occurs before the bang as a natural outcome of the novel symmetries of string theory. 而在前大霹雳学说中,加速发生在大霹雳之前,是一种弦论新对称的自然结果。
- Quantum mechanics has strongly influenced string theory, a candidate for a theory of everything (see Reductionism. 量子力学可以极大地影响线理论,一种万物理论的后备理论(请看简化论。
- Yeah,well,it's just some quantum mechanics with a little string theory doodling around the edges. 不错;只是一些量子力学而已边上还随便写了一点点弦理论.
- Historically, angular momentum is what clued in physicists to the quantum-gravitational implications of string theory. 历史上,角动量正是让物理学家注意到弦论中含有量子重力的关键。
- The study of extremal surfaces is of substantial interest in mathematics, general relativity and string theory. 极值曲面的研究在数学理论,广义相对论和弦理论中具有相当重要的地位。
- Yet so far string theory offers no explanation for the observed values of the constants. 但目前为止,弦论仍无法为已观测到的常数值提供满意解答。
- String theory overcomes some of the obstacles to building a logically consistent quantum theory of gravity. 在建构没有矛盾的量子重力论时,弦论已克服了某些障碍。
- There is also the tantalising possibility that Planck will provide support to some scenarios involving string theory. 还有诱人的可能性普朗克将提供支持,某些情况下,涉及弦理论。
- In string theory we have several extra dimensions, which results in many more adjustable parameters. 在弦论里,我们有数个额外维度,结果产生更多的可调参数。
- Before string theory, physicists were hard-pressed to imagine any mechanism that could so cleanly eliminate the singularity. 弦论出现之前,物理学家始终缺乏灵感,去想像任何能够把奇异点彻底消除的机制。
- This set of vacuum energies (or vacua, as physicists like to refer to universes) has been dubbed the anthropic landscape of string theory. 而这组真空能量(或称多真空,对应到物理学家提及的多宇宙)便被戏称为弦论的人择地景。
- Furthermore, the term that Perelman added to the basic flow used by Hamilton arises in string theory, which is a quantum theory of gravity. 除此之外,帕瑞尔曼所加到汉密尔顿瑞奇流方程式中的项,也出现在弦论(一种重力的量子理论)之中。
