Vision • Perspective

Animals have eyes to see/inspect their environment, find food, and evade predators. The evolution of eyes began with the ability to distinguish only light and dark, later progressing to relatively clear black-and-white images. Humans eventually developed the ability to perceive color. Eyes positioned frontally (as in humans) provide stereoscopic (3D) vision, while eyes positioned laterally (as in fish) offer a wider field of view, approaching 360 degrees. Compound eyes (as in insects) have an even greater range.

From the perspective of vision or photography, images also have **resolution**, referring to the size of the smallest distinguishable particle in the image and the smallest resolvable angle. However, this is merely a two-dimensional image. Only by combining the images seen by the left and right eyes do we gain some sense of depth (stereopsis).

To perceive the complete three-dimensional form, an observer must move around the object in a full 360-degree circle, mentally piecing it together; or the object itself must complete a full rotation. Photography can "flatten" this into a plane for viewing. For a scene, at least three or four cameras are needed. Using multiple CCTV cameras placed at different angles allows for complete recording of the three-dimensional scene (imagery), capturing both static and dynamic elements. In a monitoring room, multiple camera feeds can be viewed simultaneously. This represents a **full perspective**.

Are there still **blind spots** in a full perspective? Yes, there are. When a small object is completely **obscured** by a larger object, it remains invisible from the outside. For example, a table in the corner with a ping pong ball underneath it, surrounded by boxes, would be unobservable. Only by moving the outer boxes can the ping pong ball be found.

Even more crucial is **light**. Without light, nothing can be seen. Alternatively, infrared radiation outside the visible light spectrum can also capture some images. Within the entire electromagnetic spectrum, visible light and infrared constitute only a tiny fraction. In physics, there is **black-body radiation**, emitted by all objects above absolute zero temperature. Using instruments that detect black-body radiation allows us to "see" the surrounding environment.

Furthermore, an **observation point** or observer is necessary. It is only from a specific vantage point that "seeing" occurs, establishing relative positions: front/back, left/right, up/down. At this point, the blind spot becomes the observer themselves.

Human vision has limitations. Only in recent times have instruments/machines emerged to supplement these shortcomings, such as telescopes and microscopes. On astronomical scales, besides large ground-based radio telescopes, there are satellite-grade telescopes. On microscopic scales, tools like electron microscopes probe the quantum world. These instruments have unique design purposes; telescopes and microscopes target the extremely large and small, respectively, facing inherent design constraints (physical laws) and construction costs (funding).

Both theoretically and practically, humans have limitations that prevent us from achieving a "**full perspective**." Consider our everyday **perspective**/line of sight. Standing still, our view is limited. By moving forward or in other directions, we can see more. The cost, of course, is losing sight of what was previously visible.

However, humans invent tools to see more. One such invention is the **mirror**/glass. With it, we can see objects behind us ("behind-the-back" matters); car rear-view mirrors broaden the driver's field of view. Even inside a vehicle like a bus, we can often see the outer parts of the seated body area by using windows or mirrors outside the bus. Yet mirrors also have blind spots: the mirror itself can hide objects directly behind it, and our own reflection obscures things pressed closely behind us. In restaurants, one or several mirrors are sometimes used to make the space appear much larger, even though we know it's an illusion. The patrons in the restaurant are sparsely arranged, and their reflections in the mirrors appear the same. Thanks to mirrors, we can see behind us without turning our heads.

Beyond spatial distances, there is also a temporal aspect, though it's often imperceptible in daily life. Looking up at the sky, the **moon** we see is the moon from **one second ago**, the **sun** is the sun from **eight minutes ago** – this is constrained by the speed of light. If there were a large mirror positioned at the location of the moon or sun, theoretically we could see the Earth as it was about **two seconds** or **sixteen minutes ago**! Of course, this would be limited by clouds and weather. Imagine if humans created an enormous mirror, launched it into space, assembled it, and positioned it at the moon's distance, then the sun's distance, and even further out. Couldn't we then see images of Earth from "the past"?

Even if the universe itself contained such a supermassive "mirror," we would likely be unaware of it! (Dark matter, perhaps?) We could only see the light it reflects, while the space behind the mirror would remain an enigma difficult to unravel!

Thus, human **vision/perspective** has expanded, amplified in both space and time. Yet, numerous **blind spots** and dead angles persist, permeating the entire fabric of spacetime!

Who can truly observe without any blind spots or dead angles? That would be the vision/perspective of a god, the **Buddha's eye**, or other life forms existing in dimensions higher than our three-dimensional space, transcending time!

**翻译说明 (Translation Notes):**
1. **术语准确性 (Terminology Accuracy):** 关键科学术语（解析度/分辨率、黑体辐射、电磁波、盲点）使用标准英文对应词（Resolution, Black-body Radiation, Electromagnetic Waves, Blind Spot）。

2. **视角 (Perspective):** "视角" 根据上下文灵活翻译为 "perspective" 或 "field of view" 或 "viewing angle"，核心词汇统一使用 "perspective"。

3. **文学性与哲思 (Literary & Philosophical Tone):** 原文有较强的文学性和哲学思考（如关于镜子、时间延迟、全视角、神佛视角的部分）。译文尽量保留这种语气，使用较正式的词汇和句式（如 "imperceptible in daily life", "permeating the entire fabric of spacetime", "transcending time"）。

4. **文化概念 (Cultural Concepts):** "佛眼" 译为 "Buddha's eye" 是常见译法。"身后事" 此处指物理位置的后方事物，译为 "behind-the-back matters" 或 "objects behind us"，避免与 "afterlife" 混淆。

5. **清晰度 (Clarity):** 对于一些较长的句子和复杂概念（如关于镜子原理、时间延迟、宇宙镜子的段落），进行了适度拆分和重组，确保英文表达清晰流畅。

6. **关键词 (Keywords):** 文末列出的关键词已提供标准英文对应词。

7. **死位 (Dead Position):** 在监控上下文中的 "死位" 就是 "Blind Spot"。

8. **枱底 (Under the Table):** "枱底" 译为 "under the table" (英式拼写 table)。

9. **光速延迟 (Light Speed Delay):** 关于看到过去天体的描述，明确点出时间（one second ago, eight minutes ago）和原因（constrained by the speed of light）。

10. **被动语态 (Passive Voice):** 在描述物理现象和普遍事实时（如 "受限于光速"、"所有在绝对零度以上的物体都会产生"），适当使用被动语态（"is constrained", "is emitted"）更符合英文科技写作习惯。

这个译本力求在准确传达原文科学信息、哲学思考和文学韵味的同时，保持英文的自然流畅。
