枣树
一些不同枣树品种的接穗,
嫁接在后院几棵十几年以上的枣树上,
发现有下面几个好处,
一是不同品种成熟有早晚。
二是不同品种的枣花异花授粉,枣结的多。
还有就是接穗嫁接在大枣树上,
由于营养水分充足,它们结的枣个头大,成色好。

Veritas
Veritas, meaning truth, was the goddess of truth, a daughter of Saturn and the mother of Virtue.
It was believed that she hid in the bottom of a holy well because she was so elusive.
Her image is shown as a young virgin dressed in white.
幾何三大問題,Diophantus
------
-----
---------------------------
所謂幾何三大問題無非是,給定一個單位長度;
(方圓問題) 求作一個長度為 $\sqrt{\pi}$ 的線段。
(倍立方問題) 求作一個長度為 $\sqrt[3]{2}$ 的線段。
(三等分角問題) 先給長度為 α 的線段,求作一個長度為 x 的線段,而 x 滿足 $4x^3-3x-\alpha=0$。

Diophantus's riddle is a poem that encodes a mathematical problem. In verse, it read as follows:
'Here lies Diophantus,' the wonder behold.
Through art algebraic, the stone tells how old:
'God gave him his boyhood 1/6 of his life, 1/12 more as youth while whiskers grew rife; And then yet 1/7 ere marriage begun; In 5 years there came a bouncing new son. Alas, the dear child of master and sage After attaining 1/2 the measure of his father's life chill fate took him. After consoling his fate by the science of numbers for 4 years, he ended his life.'
Stated in prose, the poem says that Diophantus's youth lasts 1/6 of his life. He grew a beard after 1/12 more of his life. After 1/7 more of his life, Diophantus married. 5 years later, he had a son. The son lived exactly half as long as his father, and Diophantus died just 4 years after his son's death. All of this totals the years Diophantus lived.
Let D=84 be the number of years Diophantus lived,
and let S=42 be the number of years his son lived.
Then the above word problem gives the 2 equations

缠足
缠足,这一古老的封建习俗始于中国宋代,曾在几个世纪以前被视为“美丽”和“身份地位”的象征,女子自4岁起便必须缠足。
最终于1911年被废止。然而,在一些偏远的山村,延续到1939年。
目前中国现存的最后一位缠足女性已经100多岁了,而她的双脚也受束缚100余年。
中国香港摄影师Jo Farrell在Kickstarter基金的资助下,2014记录下她们缠足的情况。
缠足不仅作为一种贤惠的象征,也代表着女子对丈夫的顺从。
不论是她的伴侣还是公婆都要求女子缠足,以示对丈夫的忠诚。

語言的表達
語言的表達很多都是這樣:意思沒有太大差別,但是口吻不太一樣,表現出來的氣質大不相同。
1、I would like / I want
在飛機上,我們順口向服務人員說「我要一杯水」,聽起來也不那麼刺耳,但英文裡「I want」這個字,顯得太直接,用多了有頤指氣使之嫌。
換種口氣,你會發現服務員的笑容不一樣了。
(使喚)I want a cup of water./I want a magazine.
(客氣)I’d like a cup of water, please.
例句:I would like to bring in some new people.(我想多用一些新人。)
2、What is your meaning? / What do you mean?
要問別人「你的意思是什麼?」不要那麼直接說 What is your meaning?
這句話會聽起來像「你的人生有何意義」,似乎對方沒有存在的必要,不禮貌。
「意思」在中文裡多半是名詞,但在英文裡mean卻是動詞。應該這樣說才對:What do you mean?
例句:What do you mean by that?(你說那句話是什麼意思?)
3、You did it wrong. / I am sorry to bother you.
就算別人做錯了,也不要一開口就說 You did it wrong.
先來一句 I'm sorry to bother you. 和你的對話的人會更有意願聽你說。
例句:I'm sorry to bother you, but I ordered coffee, not tea.(不好意思,我點的是咖啡而不是茶。)
4、I'm afraid I can't. / No
有時候太直接了當就說 No,不僅不禮貌,大剌剌得罪人了還不知道,
特別是當別人要求的是一件很簡單的事情但我們卻無法幫忙時,你可以用 I'm afraid I can't.
例句:I'm afraid I can't agree to the terms.(很抱歉我無法同意你們的條件。)

大米和小麦
大米和小麦
常识,西方人和亚洲人的世界观迥异。
美国人讲究个人主义,独立并擅长分析,中国人对人生则持更整体的观念,强调相互依赖和所处环境。
“亚洲人模式”思考的长江以南,
以及居民观念更贴近西方人的长江以北。
在中国6个测试区域对1162名汉族大学生展开研究。
测试内容包括“三元组任务”,即为参试者提供多个3个事物的组合,并问他们哪两个事物应放在一起。
例,如果3个事物是“火车”“汽车”和“轨道”,倾向于个人主义且善于分析的人会将“火车”和“汽车”放在一起,因为两者属于同一类型(运输方式)。
相比之下,来自“整体论文化”的参试者更有可能将“火车”和“轨道”放在一起,因为“它们存在功能关系。”
研究人员让参试者画自己的社交网络,“用圆圈代表个人和朋友。”
与参加同类测试的欧洲人非常相似,来自“小麦省”的人将代表自己的圆圈画得明显大于代表朋友和熟人的圆圈。
“我们将此解读为下意识的‘自我重要’(标志),”托尔汉姆解释说。
“据我所知,美国人的自我膨胀甚于我研究的所有其他文化的人。
来自‘大米’区的中国人通常不自我膨胀,但‘小麦’区的中国人会膨胀。”
托尔汉姆及同事注意到,大米是劳动密集型庄稼,需要包括水坝和沟渠在内的复杂基础设施。
他们认为这产生一种能意识到人类相互依存的文化。
相比之下,北方农田更有可能种植小麦,种植更简单并赋予种植者相当程度的独立性,这种经历催生出截然不同的思维方式。
