      <description>Another &amp;ldquo;not my day job&amp;rdquo; essay squeezed out of me. It started because a reader asked for a sequel to &amp;ldquo;The Creator&amp;rsquo;s-Eye View,&amp;rdquo; and I realized that piece left a giant hole unfilled. Today I&amp;rsquo;m filling it. Also, a book recommendation: Dan Levitt&amp;rsquo;s What&amp;rsquo;s Gotten Into You. I lost two nights of sleep after finishing it. This one&amp;rsquo;s long — bear with me, you won&amp;rsquo;t regret it.&#xA;I. Link to heading In &amp;ldquo;The Creator&amp;rsquo;s Perspective,&amp;rdquo; our hero Fat Jin&amp;rsquo;s brain short-circuits on the subway and he blurts out the eternal question: &amp;ldquo;Why do some piles of star-ash get to force the rest of us into 996, while we&amp;rsquo;re the ones stuck grinding?</description>

      <title>The Secret Underworld of North American Chinese Supermarkets</title>

      <description>A few days ago I read an article called &amp;ldquo;A Close Look at America&amp;rsquo;s Old-Money Chinese Families,&amp;rdquo; which dug all the way to the bottom of dynasties like the Pei family (I.M. Pei), the Chao family (Elaine Chao), and the Wang family (An Wang). Fascinating read — but also a bit of a letdown, because these families feel a million miles away from ordinary people like us. A Chinese person in North America can go their entire life without meeting a single Pei or Chao.</description>

      <title>Part 3: The Sanctuary of Ascension – Our Own Genesis</title>

      <description>Introduction Link to heading In Part 1, we descended along physics&amp;rsquo; &amp;ldquo;dimensional reduction chain,&amp;rdquo; catching a glimpse of the universe&amp;rsquo;s perfect, smooth top-level design from the 11D M-Theory—a Utopia ruled by elegant equations.&#xA;In Part 2, we swam upstream and saw how Nature, the ultimate &amp;ldquo;Construction Foreman,&amp;rdquo; used the &amp;ldquo;lazy&amp;rdquo; algorithm of fractal geometry to pile together a rough, shattered, yet hyper-efficient &amp;ldquo;leftover&amp;rdquo; reality.&#xA;If Part 1 was the &amp;ldquo;theoretical blueprint&amp;rdquo; and Part 2 was &amp;ldquo;Nature&amp;rsquo;s physical build,&amp;rdquo; then this Part 3 is the manifesto of us—the bipedal apes trapped in 3D spacetime—sounding the horn of counterattack.</description>

      <title>Part 2: Resisting the Dimensional Strike: The Leftover World Abandoned by Integer Dimensions</title>

      <description>The grandest, most &amp;ldquo;smooth&amp;rdquo; theoretical layers of the universe (from M-Theory down to Newtonian Mechanics) represent the ultimate Utopia in the eyes of physicists.&#xA;In this sequel to What a True &amp;ldquo;Dimensional Strike&amp;rdquo; Actually Looks Like, we are executing a hard pivot: falling from the ideal straight into reality.&#xA;When we step away from those pristine, perfect equations and actually open our eyes to look at the world, we discover a glaring truth: God is actually a &amp;ldquo;lazy&amp;rdquo; architect.</description>

      <title>Part 1: What a True Dimensional Strike Actually Looks Like</title>

      <guid>https://jinjiefan.com/posts/2025-09-01-true-dimensional-strike-actually-looks-like/</guid>
      <description>The chain of dimensional strikes (dimensionality reduction) in physics is essentially a top-down degradation from the highest-dimensional frameworks of the universe.&#xA;With every step down in dimensionality, the theory gets closer to human observation and our everyday understanding of reality.&#xA;But the tragic irony is this: even when these theories degrade all the way down to the bottom layer—classical physics—99% of people still don’t truly understand them. This essentially dooms the vast majority of us to ignorance.</description>

The reason I haven&amp;rsquo;t followed up is simple: the analysis from back then still holds up today.&#xA;But &amp;ldquo;tomorrow&amp;rdquo; might be a different story.&#xA;Let&amp;rsquo;s dive into the long-standing feud between Apple and Nvidia to explore the potential wildcards of the future.&#xA;1.

      <description>(Note on the title: The Chinese title &amp;ldquo;皮毛&amp;rdquo; literally translates to &amp;ldquo;Fur&amp;rdquo; or &amp;ldquo;Pelts,&amp;rdquo; referring to the fur trade discussed in the article. However, in Chinese, &amp;ldquo;皮毛&amp;rdquo; is also a common idiom meaning &amp;ldquo;superficial knowledge&amp;rdquo; or &amp;ldquo;scratching the surface.&amp;rdquo; The title serves as a clever double entendre).&#xA;Lately, the world has been somewhat chaotic, seemingly reverting to the law of the jungle where the strong prey on the weak. To distinguish the signal from the noise, we need to zoom out and look at a longer timeframe.</description>

      <description>It&amp;rsquo;s been a while since my last update. It&amp;rsquo;s the end of the year, so I need to find some excuses for myself and take the opportunity to vent a little.&#xA;To be honest, I&amp;rsquo;m a bit puzzled: we can now converse with knowledgeable and incredibly smart AI anytime, anywhere. Who still needs to read public accounts? After a tiring day at work, isn&amp;rsquo;t it better to watch short videos?</description>

      <description>This update is slower, mainly due to eye issues.&#xA;With the progression of presbyopia, my eyes can&amp;rsquo;t adapt to the three different distances of a phone, laptop, and external screen. Not only are the prescriptions different, but the pupil distance and height also vary, and progressive lenses have severe field-of-view width issues. There is no ideal solution.&#xA;I&amp;rsquo;ve heard that many people in their forties and fifties have early artificial lenses, allowing them to live and exercise without glasses.</description>

      <description>The podcasts I default to while driving lately are &amp;ldquo;Left and Right&amp;rdquo; and &amp;ldquo;Journey of Civilization.&amp;rdquo; I listen to almost every episode of the former, while the latter is like an old tree blooming anew.&#xA;Why I enjoy listening to them is not the topic of today&amp;rsquo;s discussion. I just always felt something was missing, but couldn&amp;rsquo;t quite put my finger on it. A random thought broadened my perspective.&#xA;Topics in the humanities are indeed fascinating: history, culture, society, thought, religion, literature, art, etc.</description>

      <description>Recently, there&amp;rsquo;s been a highly anticipated new book in the semiconductor industry, with a title that&amp;rsquo;s both particularly short and particularly long.&#xA;This book is &amp;ldquo;Focus,&amp;rdquo; with the subtitle &amp;ldquo;The ASML Way—Inside the Power Struggle Over the Most Complex Machine on Earth.&amp;rdquo;&#xA;The book was first published in Dutch and English, and I noticed that a Chinese version has already been signed by a domestic publisher. However, after reading it, I can&amp;rsquo;t help but pour a little cold water: due to the strict requirements of domestic publishing, a large portion of the content, possibly even one-fifth, might need to be deleted or revised.</description>

      <description>Q: After NVIDIA (NVDA) recently surged to a high of $1000(before 2024 split), there has been intense debate between bulls and bears, with many comparing it to Cisco&amp;rsquo;s peak during the dot-com bubble. What are your thoughts?&#xA;A: In most cases, using old data to predict the stock market in the short term is not very meaningful: there are too many variables, and the probability of a situation repeating exactly is extremely low.</description>

      <description>Today is New Year&amp;rsquo;s Day, so let&amp;rsquo;s dive into a light yet heavy topic.&#xA;There&amp;rsquo;s something quite intriguing about the fact that golf tournaments offer exceptionally high prize money, yet we rarely see Chinese male players on the international stage.&#xA;How high are golf prizes? The top 100 players can earn 15 million RMB a year: pure prize money, excluding endorsements and other income.&#xA;Unlike our current state of resignation in sports like soccer and basketball, golf involves no direct physical confrontation.</description>

      <description>As we all know, the world of semiconductors can be a complex and highly specialized industry that involves intricate cross-technologies and geopolitical considerations. Consequently, it cannot be reduced to simple tags like red and blue OR black and white.&#xA;While most people may not be interested in the facts or the truth, they still want to be right.&#xA;Zeku&amp;rsquo;s shut-down touched me deeply, and I have taken the liberty of revising it for everyone&amp;rsquo;s criticism.</description>

      <description>During my vacation, I had the pleasure of reading two memoir articles written by my father. It left me deeply moved. As time passes, memories tend to fade away, and the collective memory of society fades even more quickly. The official histories often focus on the nobility and high-ranking officials, leaving behind the tales of common people. Without being recorded, these stories and moments disappear without a trace.&#xA;My family name is Jin, and we are of Han ethnicity, not descended from the Korean or Manchu ethnic groups.</description>

      <description>In the wake of recent events, questions have arisen among tech enthusiasts, investors, and everyday people, with inquiries such as &amp;ldquo;Why did Silicon Valley Bank collapse?&amp;rdquo; &amp;ldquo;What happened with Credit Suisse?&amp;rdquo; &amp;ldquo;How did Bitcoin surge so much?&amp;rdquo; &amp;ldquo;Is OpenAI really that disruptive?&amp;rdquo; and &amp;ldquo;What&amp;rsquo;s the deal with AI in China?&amp;rdquo; This month, we&amp;rsquo;re going to blow the lid off these topics.&#xA;First, let&amp;rsquo;s talk about the financial disruption.&#xA;Traditional banking systems, particularly foreign banks, may face significant issues in the next ten years.</description>

      <description>This article was written during the Chinese New Year period, and it summarizes my personal experience of struggling with eye problems for many years.&#xA;In the late 1990s, I once attempted to become a programmer. Unfortunately, I encountered a serious problem - eye fatigue.&#xA;Back in the day, CRT was the predominant type of computer monitor, and the level of eye strain and flicker was so severe that I estimate people nowadays couldn&amp;rsquo;t bear to look at it for more than 10 minutes.</description>

      <description>Chapter One Link to heading In our discussion of the &amp;ldquo;Lithography Machine Battle,&amp;rdquo; we mentioned that Nikon and IBM were betting on EBDW (E-beam Direct Write, also known as EPL or Electron Beam Projection) when crossing the 193nm threshold.&#xA;The wavelength of a 100KeV electron beam is only 0.004nm, which provides a much greater resolution advantage compared to EUV. Additionally, electron beams can be used with mature magnetic lenses, unlike EUV which requires reflective mirrors.</description>

      <description>This article may overturn some people&amp;rsquo;s understanding. The reason is simple: fragmented information from sensationalist media may not necessarily form a meaningful whole.&#xA;Is 5G a battle for the nation&amp;rsquo;s fate?&#xA;Unfortunately, I have to tell those pink-faced friends who crave war after enjoying forty years of peace that it certainly is not what they are looking for.&#xA;Why?&#xA;Not to mention that the use of 5G is still unclear, but the entry barrier for 5G has actually been lowered instead of raised.</description>

      <description>On December 12, 2014, Professor Zhao Dajian of the School of Life Sciences at Nankai University passed away due to illness. However, there was almost no media coverage, and no journalist wrote any articles using emotional rhetoric such as &amp;ldquo;the father of Chinese xanthan gum&amp;rdquo;. Today, the Chinese xanthan gum industry, which ranks first in the world in terms of production, has not published any mourning articles.&#xA;You may have never heard of xanthan gum, but you and your children likely eat it frequently because it commonly exists in a wide range of popular foods such as ice cream, ketchup, jelly, yogurt, soy sauce, mixed grain porridge, cheese, bread, and cake.</description>
