跨時空而來8-後記 （憤怒）
（凱歌高唱 ，天人合一，共譜佳音—恆河之歌。）
早上另一位印度聖者，
指著南禪精舍的電風扇，
要求我用電風扇解釋氣流，（我哪有那麼厲害？😄😄😄）
祂用意念暗示我說：
我看過愛因斯坦的理論我懂！
（阿爾伯特·愛因斯坦（德語：Albert Einstein，1879年-1955年）
他非常憤怒於，把聖者指責為魔的言論。
簡單的電風扇就可以說明氣流問題，
當然，佛法的神通完全可以解釋清楚。
問題是台灣一堆厚顏無恥之人，我有什麼辦法呢？
想起我吞進去的神通文章，

AI 摘要
用電風扇的氣流來比喻與解釋地球的大氣層，是一個非常生動且切合物理原理的類比。
大氣層中的空氣運動、熱對流與壓力變化，
都可以透過想像我們身邊的風扇運作來找到對應的觀念。
動力來源與循環
太陽如同馬達：電風扇需要插電來推動空氣；
地球的大氣層則是由「太陽」提供源源不絕的熱能，
加熱赤道與高緯度地區，驅動全球的風向與大氣循環。
空氣薄薄一層：地球半徑約 6,400 公里，而我們的大氣層主要集中在底部 10 到 100 公里內。如果把地球比作一顆籃球，大氣層就像是貼在球面上的一層薄薄灰塵或保鮮膜，
如同風扇吹出的氣流只在表面薄薄的空間裡流動。
對流與氣壓
冷熱對流：打開暖氣或電風扇時，熱空氣上升、冷空氣下沉，這就是流體的自然對流。大氣層中的對流層也是如此，地表被太陽晒熱後空氣膨脹上升，高空冷空氣下沉，形成雲、雨和日常的天氣變化。

氣壓與風速：風扇轉動時會製造出壓力差（前方壓力小、
後方壓力大或邊緣流速快），空氣就會從高壓處流向低壓處。地球上的高氣壓與低氣壓中心也是同樣的道理，
空氣不斷流動就變成了我們感受到的風。

邊界與阻力
地表摩擦：把手伸到運轉的電風扇後面會感覺有吸力與亂流，
是因為扇葉或障礙物干擾了氣流。
在大氣層最靠近地表的地方，也有一個「大氣邊界層」，山脈、森林和高樓大廈就像大自然的粗糙障礙物，會減緩地表的風速，越往高空走阻力越小，風也就越強。

沒葉片更涼快─無葉風扇原理圖解 - TechNews 科技新報
2014年8月9日 — line share. 沒葉片更涼快─無葉風扇原理圖解. 沒有扇葉還能叫做電風「扇」嗎？
吹得出風來嗎？「無葉風扇」就是這樣神奇的新電器，
一起來揭發其中的奧妙吧！
面對炎熱的夏天，你是否常常賴在電風扇前猛吹，手上還拿著扇子猛搧風呢？
不論扇子或電扇，能讓你覺得涼爽的原因，
都是讓空氣流動，加速帶走人體皮膚表面的汗液和熱氣。...
Across Time and Space 8-Postscript─Anger
(Victorious songs resound; heaven and humanity unite, sharing auspicious news—Song of the River Ganges.)
This morning, another Indian sage pointed at the electric fan in Nanchan Monastery and asked me to use it to explain airflow. (How could I possibly be that capable? 😄😄😄)
He conveyed through thought that he knew I understood Einstein’s theories.
(Albert Einstein, 1879–1955)
He was very angered by statements that labeled the enlightened Sage as a demon.
A simple electric fan is enough to explain the problem of airflow.
Of course, Of course, the spiritual powers in Buddhism can be clearly explained.
The problem is that there are many shameless people in Taiwan; what can I do about it?
Thinking of the article on spiritual powers that I had previously held back,
I ended up writing Across Time and Space 8-2 (Spiritual Powers).
The enlightened Sage said, “He wants to name it ‘Song of the Ganges.’”
Master Banji
Using airflow from an electric fan as an analogy to explain Earth’s atmosphere is a vivid and physically meaningful comparison.
The movement of air in the atmosphere, heat convection, and pressure changes can all be understood by comparing them with how a fan operates.
Energy Source and Circulation
The Sun is like the motor. An electric fan needs electricity to move air, while Earth’s atmosphere is driven by continuous energy from the Sun. This energy heats different regions of the Earth, especially the equator and higher latitudes, which drives global wind patterns and atmospheric circulation.
The atmosphere is extremely thin. Earth’s radius is about 6,400 km, while most of the atmosphere is concentrated within the lowest 10 to 100 km. If Earth were a basketball, the atmosphere would be like a very thin layer of dust or plastic film on its surface—similar to how air from a fan moves within a very thin surrounding space.
Convection and Air Pressure
Warm air rises and cold air sinks, which is natural convection. This is the same process as when a heater or fan operates: heated air expands and rises, while cooler air descends. In the troposphere, this process forms clouds, rain, and daily weather changes.
Wind is also caused by pressure differences. When a fan rotates, it creates differences in air pressure and airflow speed. Air moves from high-pressure areas to low-pressure areas. In the same way, high- and low-pressure systems on Earth continuously move air, creating wind.
Boundary Layer and Friction
Near the ground, terrain creates friction. When you place your hand behind a running fan, you can feel turbulence and suction caused by airflow disturbance. Similarly, Earth’s lowest atmospheric layer—the boundary layer—is affected by mountains, forests, and buildings. These obstacles slow down wind near the surface, while wind becomes stronger at higher altitudes where there is less friction.
Why Fans Make Us Feel Cool
The sensation of cooling from both fans and hand-held fans comes from air movement. Airflow removes heat and sweat from the skin more quickly, making us feel cooler.
An article from TechNews explains that even bladeless fans work on the same principle: they do not “create” cool air, but accelerate air movement, which enhances heat and moisture removal from the skin, especially during hot weather.
