继续发表有关斥力子的文章,请指正。
“斥力子理论”对物理学的影响1
庄一龙
近年来,由中国学者创立的“斥力子理论”,经过中国科学院《科技促进发展》《
科技成果管理与研究》、《科技中国》、《中国科技财富》、《中国科技成果》等主流
科技杂志报导后,引起了学术界广泛重视。那么,这一理论究竟有那些观点震动了学术
界,值得人们如此关注呢?
“斥力子理论” 是一种新物质作用理论,实际上也是一种物理哲学理论。它的代
表性文章是《论“斥力子”的存在及其意义》,另外还包括《相对性效应和牛顿定律的
本质》、《物理学中精细结构常数的理论推导与解释》等几十篇论文。同牛顿的苹果从
树上掉下来的万有引力理论相对应,这是一个可称作“苹果如何转移到树上去的‘万有
斥力’理论”。该理论认为,地面的物体一旦动起来,不管方向如何,都具有一种挣脱
地球引力的能力,就好象物体吸收了一种对抗万有引力的物质那样。“斥力子理论”把
普朗克能量子看作是一种对抗引力的实物粒子,称它为“斥力子”,并认为物体运动状
态的改变就是由于吸收或释放斥力子造成的。
在思维方法上,它有两个根本突破:其一,是把抽象的能量概念实物化,使能量有

来自主题: Physics版 - 又有磁单极发现了?
科学家首次在实验室制造出传导磁场的“虫洞”时空隧道,因此提示宇宙的三维空间之
外还存在另外的空间。
据“每日科学”(science daily)网站9月3日报导,西班牙巴塞罗那自治大学(
Universitat Autònoma de Barcelona)的科学家在实验室内,使用超材料和超导界面
建立了磁场传送隧道。他们检测到,在产生磁场的磁力源远端,出现了不可能在自然界
中单独存在的磁单极子。
报导说,这一实验结果让科学家感到很惊讶。其结果只能解释为,磁场的一个磁极被传
送到另外的部位,但是传送过程与途径是无法被检测出来的,这个隐形的传送过程与途
径就是超出常规三维空间的另外空间。
首席研究员阿尔瓦‧桑切斯(àlvar Sánchez)解释道,磁场虫洞是引力虫洞的
模拟形式,因为磁场虫洞“改变了空间的拓扑性质(topology),其条件是磁力清除空
间中的内区(inner region)。”
报导说,实验结果也提示,人们能够更好地利用磁场,比如在医疗中的核磁共振(MRI
)领域,可以实现远程核磁共振检查而不必让病人进入或靠近检测仪器,因此让病人感
到更舒适。

A fundamental puzzle is that the more I read political science, the more I
feel anything goes. Hence my bias is that I have no bias toward Theoretical
Approaches, Level of Analysis and Quantitative vs Qualitative Methods.
Theoretical approaches: In IR, realism, liberalism and constructivism each
focuses on different aspect of the complex reality of world politics. When I
talk with a liberalist, my point is more toward realism, however when I talk
with a realist, I feel that liberalism has a role

hehe, good questions. Here is my understanding...
Theoretical approaches: according to Lakatos, it's theoretically degenerative
to use different paradigms to explain different questions, i.e. you should not
use liberalism to explain peace while using realism to explain wars. A
theorist should be consistent and sticks to one paradigm and then improve the
paradigm according to scientific research program, i.e. you get some
assumptions,and then derive some testable hypotheses, and then use empirica

举世闻名的英国物理学家霍金(Stephen Hawking)周日首次应邀前在滑铁卢发表学术演说。听众来自政商学界,包括安省省长麦坚迪、联邦工业部长甘礼民(Tony Clement)、联邦财长费拉逖。
霍金发表学术演说
1999年,黑莓手机生产商 Research In Motion创办人之一的Mike Lazaridis创办圆周理论物理研究所(Perimeter Institute for Theoretical Physics)。霍金后来接受该研究所邀请担任研究工作。
据悉,目前圆周研究所正在扩充,希望对宇宙的研究可以有进一步的突破。研究所的面积已增加一倍、研究员增加了两倍,另外还增添一新翼,以霍金的名字命名。霍金在演说中称:“圆周是伟大的物理理论。我希望、我预料,伟大的事情会在这里发生。”
圆周研究所所长图罗克(Neil Turok)表示:“人在科学方面的成就,霍金足为典范。”他指出:“霍金不断地推陈出新。他是真实的、活生生的科学家,他仍然有创造力。”
霍金二十余岁时,患上肌肉萎缩症,令他全身瘫痪,发声也要倚赖电子仪器;不过智力没有受到影响。霍金在演说时先说:“大家听见我吧?”但那

haha. lookat HUYu's comments: here was a superb scholar of most impressive
credentials. (Let's call him our magnificent Uncle Sam.) He is however, no
farmer, that is, our humble farmer of low origin, who may grace your
fragranced face with his dirty spit from time to time. Our scholar moves
into the village, and tries his hand in planting our most high-yield rice to
endow his new found community with, let's say, additional happiness. (Let's
call it democracy.) It is hard labour indeed. After two... 阅读全帖

方方面面基础无比浅薄
还是虚心好
中国如果说有点技术的话

若不虚心,theoretical的东西不会有提高
做出来的东西难以达到elegant的层面
还是ad hoc, 土鳖
肤浅不堪
