日语之奇怪的ある

“ある”对应基本意思是“有”,即“have”。但这句

1
森さんは学生ではありません。

译为“森先生不是学生”,“ある”表示的意思却是“是”,即“is”,“ではありません”是“ではない”的敬语形式。

那“森先生没有学生”该怎么说呢?

先来看“あります”和“います”的区别,
“あります”用于花、草、桌子等不具有意志的事物。
“います”用于具有意志的人、动物或昆虫。

いすが部屋にあります。
こどもは公園にいます。

再在《标日》中找例句

2
スミスさんの家にはプールがあります。
(わたしの)うちには子供がいません。

如此我们得到“森先生没有学生”的说法

森さんには本がありません。
森さんには学生がいません。

《旷野之息》中有趣的事情

  • 盾反的速度可以超过光速。
  • 中国人在喜事上吹唢呐,在悲事上也吹唢呐。我在《旷野之息》中打wetland的西诺克斯Hinox独眼巨人时听到了唢呐,同样我在一些韩国电影中也听到过唢呐。
  • 《旷野之息》里怪物会骑马,而人类在村中商店里公开售卖怪物的guts,是怪物野蛮,还是人类野蛮?
  • 在双子山,隔着屏幕,我起了同现实中一样的恐高反应,双脚发软不敢往下看。
  • 在双子山的神庙A记下了球阵的摆放位置,我就去神庙B成功地还原摆放位置完成神庙B的挑战,之后我认为神庙A的门也已打开可直接领取神庙A的精神球,于是头也不回过去了……
  • 既然红月是盖侬为了让怪物们起死回生而出现的,那么闪电一定是盖侬在打击林克。
  • 有人建议新人先不要玩旷野之息,说Link一个人太孤单了。而我认为从某个角度可把游戏分为几类,有一种是游戏内多人玩家一人,如《最终幻想》;有一种是游戏内一人玩家多人,如《旷野之息》。
  • 电视剧我只看历史或现实剧,而《旷野之息》都是虚构的,可我却觉得真香。石中剑?

还在玩……

ipad充电变绿色但长时间电量不长

ipad插上充电后,屏幕右上角电池图标显示为绿色,但这样放着过了两三个小时,电量还是不长!

大概由于天气冷的原因。

解决方法,我称之谓点火充电。就是使ipad处在插电充电状态时,在ipad里运行一个3d游戏之类的app,这样cpu和gpu都处于高速运转状态,ipad很快会升温,过几分钟看看电量百分比长没长,正常情况是会长几个百分比的,这时要么一直让3d游戏跑着,要么关掉ipad,将ipad用被子盖好,就这么一直插线充电。

从频率角度说明音程的和协性

从频率角度讲,C与高一个八度的C相差2倍。一个八度被分成12项的等比数列,公比为2^(1/12),即2的12分之一次方。
以下是各音的国际标准频率值

1

C - do - 261.6 Hz
D - re - 293.6 Hz
E - mi - 329.6 Hz
F - fa - 349.2 Hz
G - so - 392 Hz
A - la - 440 Hz
B - si - 493.8 Hz

在钢琴键盘上可以看到,C与F相差5个半音,C与G相差7个半音,我们来验算一下

>>> import numpy as np
>>> 261.6 * np.power(2, 5/12)
349.19410585088104 # F - 349.2 Hz
>>> 261.6 * np.power(2, 7/12)
391.95713131093993 # G - 392 Hz
>>> 261.6 * np.power(2, 9/12)
439.95700446074346 # A - 440 Hz

乐理中说

3
八度(12个半音)极完全协和
纯四度(5个半音)、纯五度(7个半音)完全协和
三全音(6个半音)不协和

为什么纯四度、纯五度协和呢?
两个音之所以协和,是因为彼此之间是简单的倍数关系,如八度是2倍的关系。
纯四度是2^(5/12)倍关系,纯五度是2^(7/12)倍关系,不是简单倍数啊!
其实,2^(5/12)约等于1+1/3即4/3,2^(7/12)约等于1+1/2即3/2
我们在python中验算一下

1
2
3
4
5

>>> np.power(2, 5/12)
1.3348398541700344
>>> 1+1/3
1.3333333333333333
>>> np.power(2, 7/12)
1.4983070768766815
>>> 1+1/2
1.5

另外,
1+1/5即6/5靠近2^(3/12),所以相隔小三度(3个半音)比如C键与Eb键同时发声时不难听;
1+1/4即5/4靠近2^(4/12),所以相隔大三度(4个半音)比如C键与E键同时按下不难听;
1+2/3即5/3靠近2^(9/12),所以相隔大六度(9个半音)比如C键与A键同时发声时不难听。
这是三和弦、七和弦存在的理论前提。

而三全音是2^(6/12)倍即根号2倍的关系,是无理数,所以不协和,如C键与F#键同时按下,或者F键和B键同时按下就难听。

我们举一个生活中的例子,弦长与频率成反比,我们拉直一根弦,这时我们把此弦看成数轴,原点在固定弦一端的地方,随便手捏住弦的另一处,弹此弦定为C音,手捏的点则为数轴上刻度为1的位置;再手捏的刻度为3/4处则发出F(fa)音;手捏的刻度为2/3处发出G(so)音;手捏的刻度为2处发出低一个八度的C音;而手捏刻度为1/2处发出的是高一个八度的C音。

GTA5剧情进行不下去了

每天就只能拉Lamar出来hang out,无其它正事可做,在街上和别人飚车总是输,到右上角酒吧和人开火总是被干死。

问题出在哪?原来前两次去Simon的店都是从其店侧门进的,于是之后都开车去Simon店的侧门,而其店侧门总是拉下关着的,打电话给Simon也不接,因此剧情就这样进行不下去了。

原来可以到Simon的店的正门处遛哒一圈,就会遇到Simon触发正剧情。

后期与Lester干一大票时要到的一个工厂,也是大门关着的,围着工厂绕了一整圈,才在不起眼的一面有个门可以进去。

自由枪骑兵Freelancer执行任务时为什么无法检起名单

微软出品的精品宇宙机战游戏自由枪骑兵Freelancer中,刚开始时在Pittsburgh星球的酒吧中接到一个任务:到废虚的指定地点打掉几架Liberty流氓战机杀死Barry Drucker后要求检起一份名单,应该靠近名单时点键盘上默认的B键就可以了,可死活没反应。

想了好半天,原来是我们的战机的货物舱是满的,装不了名单,唉,游戏也不给一个提示!

先离名单远一点,点击屏幕右上角存货按钮,点击每一件存货,会在其边上出现清空按钮,就这样抛出所有存货,再回到名单物处,这时按键盘B键就可牵引名单,就出现任务完成的提示了。

记得之后再回到抛存货处把原来的物器牵引回舱。

A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful. And most certainly, fear is now widespread, gripping even seasoned investors. To be sure, investors are right to be wary of highly leveraged entities or businesses in weak competitive positions. But fears regarding the long-term prosperity of the nation's many sound companies make no sense. These businesses will indeed suffer earnings hiccups, as they always have. But most major companies will be setting new profit records 5, 10 and 20 years from now.

As illustrated in below, draw rays from 0 through Z(t) and Z(t+1), together with circular arcs (centred at 0) through those points.

Recovering from our feigned bout of amnesia concerning complex numbers and their geometric interpretation, Cotes' result becomes simple to understand and to prove.

However, not any old mapping qualifies as motion, for we must also capture the idea of the sheet remaining rigid while it moves.
Armed with this precise concept of motion, our final definition of geometric equality becomes...
buf for the moment we wish only to explain how Klein was able to generalize the above ideas so as to embrace such new geometries.
But will this type of equality behave in the way we would like and expect?
If M and N are members of G then so is the composite transformation.
If two transformations do not alter distances, then applying them in succession will not alter distances either.

In a full-throated defence of America’s forward-leaning stance abroad, John F. Kerry, US Secretary of State, hit back at critics who have claimed that the United States is disengaging from world affairs. “I want to make it clear that nothing could be further from the truth,” said Kerry.

he first studied the transformations that now bear his name, it is fair to say that the rich vein of knowledge which he thereby exposed is still far from being exhausted. For this reason, we shall investigate the transformations in considerably greater depth than is customary.

Check for yourself that the order in which we apply these mappings is immaterial.
the result is true without qualification.
We should explain that this is not generalization for its own sake; soon we will see how this three-dimensional inversion sheds new light on two-dimensional inversion.

If the conformality of an otherwise conformal mapping breaks down at a particular point p, then p is called a critical point of the mapping.

Thus instead of merely saying that f(z) "dies away to zero like (1/(z^2)) as z tends to infinity", we can now say (more precisely) that f(z) has a double root at z = infinity.

From the similarity of the illustrated right triangles with hypotenuses Nz1 and Nz, we immediately deduce that.
