Stephen Hawking’s Legacy | Confirmation of the Black Hole Area Theorem Through Gravitational Wave Astronomy

September 7, 2025 cialu Technology

Stephen Hawking’s scientific legacy is deeply rooted in the fundamental understanding of gravity, black holes, and the underlying connections between quantum theory and general relativity. Among his most profound contributions is the formulation of the Black Hole Area Theorem in 1971, which has now been empirically confirmed through gravitational wave observations by the international LIGO–Virgo–KAGRA (LVK) network. This breakthrough not[…]

Mastering Aperture in Photography. A Simple, Easy Guide 📸

October 17, 2024 cialu Technology

Aperture is a fundamental concept in photography, playing a crucial role in determining both the exposure and the depth of field in an image. Alongside shutter speed and ISO sensitivity, aperture forms the “exposure triangle,” which photographers manipulate to achieve desired visual effects. This article delves deep into the mechanics of aperture, its effects on imagery, and practical guidance for[…]
