[Culture] 創造宇宙- 希臘神話 聖經 The creation of universe: Greek Mythology Vs Bible

喺希臘神話入面,混沌係創造世界之前存在嘅空虛。呢個係一個冇嘢同空虛嘅狀態,缺乏秩序同結構。由混沌出現咗第一個神,即係原始人,標誌住宇宙嘅開始。喺聖經宇宙學入面,有人話上帝係由"無"創造"宇宙", exnihilo (Out of nothing) ,好似希臘神話入面嘅混沌噉。兩個概念都涉及到創造世界之前嘅空虛或者無。 請記住,希臘神話係早於聖經。

In Greek mythology, Gaea is the Earth mother goddess. Erosis the god of love and desire. Erebus is the personification of darkness, and Nyx is the goddness of night. They're among the primordial deities born from Chaos, representing fundamental forces and concepts that shapes the universe.

In Greek mythology, Chaos was the void that existed before the creation of the world. It was a state of nothingness and emptiness, lacking order and structure. From Chaos emerged the first deities, the primordials, marking the beginning of the universe.

There is a similarity between Chaos and Big Bang. While both the concept of Chaos and the Big Bang theory suggest a fundamental transformaton, the former is rooted in myth and symbolism, whereas the latter is based on scientific evidence and observation. Nonetheless, both ideas touch upon the idea of transformation and the emergence of order from disorder.

Greek mythology offers a unique perspective on the creation of the world. It's fascinating to see how these ancient stories shape our understanding of the universe and our place in it.

Further, in biblical cosmology, it's said that God created the universe from nothing, exnihilo, much like Chaos in Greek mythology. Both concepts involve a void or nothingness preceding the creation of the world. 

Remember, Greek mythology predates the Bible. The exact timing of its origin is unclear, but the earliest surviving Greek mythological texts such as Hesiod's Theogony, date back to around 700 BC. The myths themselves likely evolved over time through oral traditions, making their true age difficult to pinpoint.

[Culture] 雅典國家考古博物館 The National Archaeological Museum at Athens - Greek mythology

如果你喺雅典,又對古希臘神話好著迷嘅話,國家考古博物館就係一個必去嘅地方喇。 國家考古博物館收藏了令人驚嘆的文物,讓古老的神話栩栩如生,親愛的。你會在那裡發現古希臘眾神、女神、神話生物和傳奇英雄的故事。這些展品會將你帶回那個充滿神話和魔力的時代。

If you're in Athens and captivated by ancient Greek myths, the National Archaeological Museum is an essential destination.

The National Archaeological Museum has an incredible collection of artifacts that bring ancient myths to life, darling. You'll discover stories of gods and goddesses, mythical creatures, and legendary heroes from ancient Greece. The exhibits will transport you back in time to an era of myth and magic.

Greek mythology revolves around the stories of gods and goddesses, heroes and monsters, which were used to explain natural phenomena, the creation of the world, and human nature. Its origins date back to ancient Greece, around 800 BC, when Homer's epic poems, the Iliad and the Odyssey, started to circulate. Over time, myths were passed down through generations via oral tradition, until they were written down and eventually became the foundation of Western literature.

Some famous figures in Greek mythology include Zeus, the king of the gods, Poseidon, the god of the sea, Athena, the goddess of wisdom, and Aphrodite, the goddess of love. Then there's Hercules, a demigod hero, and Medusa, the snake-haired monster.

Indeed, Ancient Greek Mythology has left an indelible mark on human culture, shaping art, literature, philosophy, and even modern psychology. The stories of old still resonate deeply within us, speaking to fundamental human experiences and emotions.

The influence of Ancient Greek Mythology can be seen in many forms of modern media, such as film, literature, and art. For example, movies like Clash of the Titans and Hercules draw inspiration from mythological stories, while authors like Rick Riordan base their books on Greek mythology. Even psychology has borrowed terms from mythology, like "Oedipus complex" and "Narcissistic personality disorder".

Don't leave Greece without seeing this!

[FoZ] Drones for bombing Russia's Nuclear Bombers in Ukrainian's Spider Web Mission

烏克蘭的策略傾向於選擇定制的現成技術,而不是像 GRIFF 300 或 DJI FlyCart 這樣的高端民用無人機,這些技術具備以下特點:- 小型且難以被檢測- 價格低廉且易於更換- 能夠自主導航和遠程駕駛.

To achieve the Ukrainian' Spider Web mission, I would pick civilian drones with high payload and flight time. According to a source, the breakdown of top contenders combines high payload capacity with long-range endurance is summarized in Table 1. However, the drones used in Spider Web mission are different from what I thought. Here is the information from public domains:

Ukraine’s Operation Spider Web didn’t rely on a single commercial drone model—instead, it showcased a clever fusion of modified, low-cost FPV drones and open-source autopilot systems like ArduPilot. These drones were smuggled into Russia over months, hidden in wooden sheds and truck trailers with detachable roofs2. Once launched, they followed pre-programmed flight paths and could switch to manual control when close to their targets—even in GPS-denied environments.

Rather than selecting a high-end civilian drone like the GRIFF 300 or DJI FlyCart, Ukraine’s strategy leaned on customized, off-the-shelf tech that was:
  • Small and hard to detect
  • Inexpensive and easily replaceable
  • Capable of autonomous navigation and remote piloting
This approach allowed Ukraine to strike deep into Russian territory—destroying over 40 strategic bombers—without relying on billion-dollar systems. It’s a masterclass in asymmetric warfare.

Ukraine’s recent drone strikes reportedly destroyed or disabled multiple Tu-95s using small, low-cost drones equipped with modest explosive charges. The success wasn’t about raw explosive power—it was about precision, timing, and exploiting soft spots in the aircraft’s design.

The Tu-95 “Bear” is a Cold War-era strategic bomber, first flown in the 1950s. Despite upgrades, it remains a large, slow, and lightly protected aircraft. Here’s why it became such a prime target:

Exposed Parking: Russia often parks these bombers in open tarmac bays, not hardened shelters, making them easy to spot via satellite and vulnerable to drone strikes.

Structural Weak Points: Ukrainian FPV drones targeted the wing root between the fuselage and inner engine, which houses a fuel tank and supports the engine, missile pylon, and landing gear. A hit here can sever the wing or cause catastrophic fire.

Fuel Load Sensitivity: Many of the aircraft were fueled and prepped for sorties. Striking them at that moment maximized the damage potential.


Operation Spider Web: A Tactical Masterstroke
  • Ukraine’s Operation Pavutyna (Spider Web) was a year-and-a-half-long covert effort involving:
  • 117 FPV drones smuggled into Russia in trucks and launched from hidden locations.
  • AI-assisted targeting and pre-programmed flight paths to evade jamming and GPS denial.
  • Precision strikes on four major airbases, damaging or destroying over 40 strategic aircraft, including Tu-95s, Tu-22M3s, and even A-50 radar planes1.
  • Estimated damage: $7 billion in irreplaceable assets.


Strategic Implications
  • Psychological Shock: Russia’s most iconic bombers were hit deep inside its territory, undermining the myth of invulnerability.
  • Operational Disruption: With Tu-95s relocated to the Far East, round-trip missions now take up to 23 hours, reducing sortie frequency and increasing fatigue.
  • Global Wake-Up Call: NATO and other militaries are reassessing base security and the threat posed by low-cost, high-precision drones.
