而 Smolin 举出的证据居然是弦论中的超对称要求宇宙学常数非正。 此破绽一现, Polchinski 立刻就使出 “独孤九剑” 捅了过去, 因为无论在弦论还是其它物理中, 超对称都是必须破缺的, 如果只是超对称要求宇宙学常数非正, 那根本就谈不上是具有现实意义的预言。 当然, 两人的争论可能还会持续, 作为外人, 我无法...
Ans:Viscosity could be defined as the property of a fluid by virtue of which an internal frictional force comes into play when the fluid is in motion and would oppose the relative motion of its different layers. 11.What is the significance of Reynolds’s Number? Ans:We know that, Reynolds...
It considers exotic space times in which gravity creates closed time-like curves and hence permits time travel into the past. Deutsch argued that the usual paradoxes associated with such solutions of GR can be resolved by QM. He does not attempt to quantize gravity, but considers quantum ...
Hi guys, I'm new here. I am doing my final degree project and it's hard for me to understand what this paragraph means in one of the papers that I'm reading, it's about primordial black hole formation. [Talking about a spherically density perturbation] The rarefaction wave starts at ...

Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. ...
I can no longer conceive that there mightreally bea universal time, which is somehow "moving" from the past to the future. This now seems like nonsense. Something like Barbour's timeless physics has to be true, or I'm in trouble: I have forgotten how to imagine a universe that has "...
The Mediterranean Sea has been sampled irregularly by research vessels in the past, mostly by national expeditions in regional waters. To monitor the hydrographic, biogeochemical and circulation changes in the Mediterranean Sea, a systematic repeat ocean
摘要: This report discusses the following topics: electron-scattering nuclear-structure studies; coincidence electrodisintegration studies of light nuclei; pion scattering and reactions on the three-body nuclei; and pion scattering from shell-model nuclei.关键词:...
