i meant something like this: whether the ew theory is su(2)xu(1) or su(2)xsu
(2) won't a priori upset any theorist if either case turns out true.
a different category of problems are for example if the space dimension turn
out to be 4 instead of 3. this will be more significant
while particle physics had been intensively studied in the past, it seems
not to be where new mysteries lie. |

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

There are several ways theorists can build string theories. Start
with the elementary ingredient: a wiggling tiny string. Next decide:
should it be an open string or a closed string? Then ask: will I
settle for only bosons ( particles that transmit forces) or will I ask
for fermions, too (particles that make up matter)? (Remember that in
string theory, a particle is like a note played on the string.)
If the answer to the last question is "Bosons only, please!" |

李 毅 博士
内容提要
西方国际社会学（或称全球社会学）的蓬勃发展，略迟于西方发展经济学和发展政治学的发展。五十年代和六十年代，帕森斯的社会发展理论占统治地位。七十年代，社会现代化理论、依附论、世界体系论，影响广泛。现在，只有世界体系论硕果仅存。主要代表人物有颇郎伊、艾森斯塔德、墨尔、佛兰克、斯卡齐波尔、梯利、傅高义、林茨、蔡斯-丹，而影响最大的是沃勒斯坦。在亚欧非世界大体系中，中国第一长达一千多年，欧洲是边缘。1865年前后，英国产值超过中国；1900前后，美国产值超过英国；中国成了边缘。今后几十年内，中国产值有可能超过美国，并长期保持第一。果如此，则中国第一就是人类世界体系的常态。
