Due to the wear of the valve seal, compression ring, and oil ring,

in cold temperature, 10w-30 is thicker than 5w-30,

avoiding oil flowing from valve train to the combustion chamber.

Would 10w-30 reduce the consumption of oil ?

Due to the carbon deposit in the combustion chamber,

which increased the compression ratio.

Did the old car use high octane gasoline preventing from detonation ?

I forgot to turn off the headlight, and then the car battery drained off.

My car battery voltage is 2V.

The portable car battery voltage is 12V.

I want to jump start my car, but it didn't work.

I can hear the starter motor turn the engine, but it is too slow to start the engine.

So can I just connect the the portable car battery with my car battery for a while,

and wait for my car battery voltage rises up to 10V ?

(I didn't remove the car battery from my car.)

Computer simulation & Using model experiment !!

Basically, the engineer based and believed everything on mathematics.

How much confident are the engineer to claim the skyscraper is safe ?

Someone wants to become the sport coach or manager,

but he only studies a lot of knowledge from the book, news, or any articles.

Is it possible ?

How to make the breaking ball deviate (or drop) as approaching to the home plate ?

The later the breaking ball changes, the more difficult to hit.

If the breaking ball starts to change from the releasing point of the pitcher, it would be easier to

make the good contact. It is hard to deceive the the hitter.

Is there any way to make the persuasive and reasonable

comments without knowing the procedure of making this meal ?

Want the car to cruise at 60 mph

1. (Critical damping) Press the throttle until reached 60mph

larger damping ratio V.S smaller damping ratio

2. Press the throttle and then release and press throttle again

Ex :

accelerate the car to 30 mph and then release the throttle to idle

and then press the throttle again (from 28 mph to 60 mph)

3. (Overshoot) Accelerate the car over 60 mph and then back to

60 mph

Did these ways of acceleration affect Volumetric Efficiency or not ?

飢餓的盛世：乾隆時代的得與失 by 張宏傑, 重慶出版社

為何說乾隆盛世是一個飢餓的盛世，得不償失的盛世？

20140713 百家讲坛 成败论乾隆（下部）10 鸦片战争的种子

https://www.youtube.com/watch?v=Nv5I3UWYcSM&index=...

-----------------------------------------------------------------------------

看了一下書本的 preface & Youtube 內容，

這種飢餓也能叫盛世，這根本是自我膨脹到極點，吹牛不打草稿。

*這種東方文明號稱有世界 1/3 GDP，根本是笑話。

房子蓋不好

馬車不會造4輪的

人民一點尊嚴 & 思想空間 都沒有 (文字獄)

百姓吃飯都有問題

*請問東方人這樣亂自我吹牛，會感到羞恥嗎 ?

Did BMW acquire 4WD technologies from Land Rover ?

or BMW developed 4WD by themselves ?

1994: Rover Group is taken over by BMW.

then, BMW produced the first Sport Utility Vehicle X5.

Challenging Viewpoint (挑戰觀點) :

因為社會因素(文革)導致東方文明落後，是東方人在自欺欺人的。

對比一下:

同樣是走集權共產的蘇聯 (Soviet Union)，照樣誕生出偉大的

scientists, mathematicians, engineer, & 文學家, 音樂家。

Science & Engineering :

Sergei Korolev (火箭專家)

Dmitri Mendeleev

Lev Landau

Yuri Gagarin

Liberal Arts :

Leo Tolstoy

Pyotr Ilyich Tchaikovsky

Too many to list.

Truth (真理) :

號稱博大精深那國就算沒有文革，還是一樣要落後。

Sincere Recommendation :

Please 東方人不要再拿文革當理由了，在那邊自欺欺人。

東方人跟著一起念 :

天將降大任於斯人也，必先苦其心志。

Challenging Viewpoint (挑戰觀點)

東方人常說東方落後是因為秦朝統一，然後思想單一。

獨尊儒術, 文字獄, 文革。

請問博大精深東方文明，要在什麼狀態下，

才能達到 "集思廣益" ?

東方文明愛好者，你們比較喜歡

1.有六小國的東方 ?

2.還是統一下的東方 ?

選1.的人

臉上總是充滿著笑容，洋洋得意的說著 "春秋戰國 百家爭鳴"。

選2.的人

請說明心中的感想

Did omniscience include miracle ?

Numbering System :

約在西元前三世紀，古印度人發明數字記號1到9。

1, 2, 3, 4, 5, 6, 7, 8, 9

東方人最喜歡吹捧的春秋戰國，有什麼文明程就 ?

世人只要說 number 來自於古印度 (對人類文明有貢獻)，

一比之下 : 春秋戰國時期的一堆古書馬上變的黯淡無光。

Common Sense (大家有目共睹)

印度人在現在 computer science 領域裡，有著不錯的表現。

CS 的領域需要有好的 mathematics。

Challenging Viewpoint :

因為環境地理因素導致東方文明落後，是東方人自我安慰的觀點。

In fact, 東方文明根本就沒值得一提的東西。

Reason :

東方文明被海洋，高山，沙漠包圍形成一個封閉環境。

封閉 : 照道理應該是裡面的東西出不來，外面的事物也進不去。

既然是封閉環境跟外面世界沒有交流，導致東方落後，

那東方文明裡的東西是又怎麼傳出去的呢 ?

這是不因為沒有邏輯, so 講話又再前後矛盾呢 ?

Conclusion :

這樣一來東方文明所宣稱的貢獻，是不是都是假的 ?

因為東方是封閉的環境(東方人自己講的)，

那怎麼可能有東西外傳對世界文明有貢獻。

(問券調查)

親愛的回答者你們好 :

想請問你們在回答類似這類的題目時心中是做何感想 ?

東方文明號稱 博大精深 & 連綿不絕，

BUT 遇到其它文明對世界和人類做出貢獻時，

除了只會 忌妒眼紅，整天在那邊 "酸" 別人的成就。

自己東方文明卻一點貢獻都沒有。

Ex:

自己東方造不出好汽車，有錢人又要買歐美造的車，

然後又要酸別人的文明。

什麼...海納百川,有容乃大。言行一致。

東方人說都很會說，結果沒一樣做到。

東方這種文明有什麼可取之處 ?

東方 East :

格物致知 : 格不出 科學 (science)

煉丹術 : 假的還會害人。

西方 West :

Airplane - Wright Brothers

Car : Karl Benz

Lightbulb : Thomas Edison

Telephone : Alexander Graham Bell

*Too many to list.

是不是 現代化 (Modern Civilization) 就是歐美化，

導致東方人過度自卑變自大 ?

(貼心提醒)

各位東方文明愛好者請發表高見時

要記得保持理性，心平氣和回答。
