Once upon a time, a long time ago, there was this guy named Aristotle.
Pretty sharp fellow; he thought up a lot of good things. But, occasionally
he made a mistake.
One mistake he made was to toss an orange up in the air and watch it come
straight back down to his hand. Aristotle reasoned that if he was moving,
the orange would have flown... 阅读全帖

很多人把钱学森当成是物理学家,其实是搞错了,非物理专业的看到力学就想到物理,
所以把钱当做物理学家了。从方励之的文章里看到跟钱学森有关的一个事情
1986年夏,国际天文学联合会(IAU)在北京及时地召开了第124届讨论会(IAU-124)
。论题是“观测宇宙学”。这是IAU讨论会第一次以此为题。也是国际天文学联合会第
一次在北京召开讨论会。
插一个故事,IAU的组织法,像联合国,有会员国制。其中有两个会员国,正式名称分
别是:中国南京(China Nanjing),中国台北(China Taipei)。以此称呼台湾海峡
两岸政治实体,实数少见。在座的诸位,如果熟悉海峡两岸关系史,就能猜得出来,这
种称呼法,是谁的主意?(提示∶在研究 过宇宙学的学者圈子里找。)在组织国际会
议时,要特别注意正式名称。在致祝酒词时必须说∶“我们`中国南京’宇宙学家欢迎
大家来….”
就这样,各国知名的和不知名的宇宙学家们,大都被欢迎来北京了。
8月29日晚,全体与会者,像美国总统尼克松一样,在人民大会堂国宴厅受到顶级的款

据英国《每日邮报》8月5日报道,来自美国加州萨利纳斯的布里奇安妮·阿维尼翁日前
为美国43位总统创建家族树,其中42位都是13世纪英国国王约翰的后裔,只有美国第八
位总统马丁·范布伦与约翰王家系无关,但范布伦拥有荷兰王室血统。
报道称,阿维尼翁为了追踪美国历任领导人的血统,花了数个月时间搜索了50多万个人
名。她从美国第一位总统乔治·华盛顿开始,追踪所有总统的男性和女性祖先联系。她
发现除了范布伦外,所有美国总统都是英王约翰的后裔。此前,遗传学家们最多只将美
国22位总统的亲戚关系联系起来,他们主要追踪这些家族的男性成员。
阿维尼翁还发现,她本人与美国现任总统奥巴马是第18代表亲。阿维尼翁创建了总统
家族树海报。她称自己将手绘总统家族树复制本亲手交给奥巴马。

1、這是川普的「下一刀」?
可能。他31日在白宮接見美國醫藥界主管,對他們說,藥價到了「天價(astronomical)
」的地步,他要這些大藥廠賣藥給政府健保計畫的藥,應該給政府「好價錢(better
bargains)」。
2、川普會如何整頓美國的藥價?
他說,他將設法加速新藥上市的過程,他並會向藥廠為聯邦醫療保險(Medicare)與醫療
補助計畫(Medicaid),爭取更廉價的藥價。這將影響上千萬的屬於這兩項政府醫療計畫
的人的每月支出。川普說,開放競爭是降低藥價的重要方式(Competition is key to
lowering drug prices)。美國聯邦政府是世界上最大的醫藥與醫療器材的買主。
3、川普做得到開放聯邦醫保的藥價嗎?
川普自己掏腰包競選(約花了他6600萬美元),他沒有大金主,他不必向任何藥廠保證任
何新合約,所以他敢拿藥廠「開刀」。
4、這跟川普要整頓工作簽證,是同樣的情況嗎?

公历只涉及365.25天的尾数0.25天的置润问题
农历太复杂了,不但涉及365.25天中尾数0.25的置润,还涉及月球轨道27.32天和会合周
期29.50天中两个复杂的置润
更要命的是,月球会合周期不断演化,需要不断天文观察修正,即使到了21世纪,农历的精
度也只能保证50年左右
