Einstein@Home: How Volunteer Computing Helps to Reveal Pulsars and Gravitational Waves

-
Introduction: Since 2015 , the LIGO and Virgo gravitational-wave detectors have been revolutionizing our view of the universe by detecting ripples in space-time caused by colliding massive objects. This began with the first observing run (O1, 2015–2016) , when scientists впервые “heard” the merger of two black holes, confirming a major prediction of Einstein’s theory of General Relativity and opening an entirely new window on the cosmos. Each subsequent run — O2 (2016–2017) , O3 (2019–2020) , and the most recent O4 (2023–2025) — has increased in sensitivity and duration, producing an ever-growing catalog of discoveries that reveal how compact objects like black holes and neutron stars form, interact, and collide across the universe. Timeline of Key Discoveries & Contributions 1967 – Pulsars discovered Radio astronomers discover the first pulsars, revealing the existence of neutron stars and opening an entirely new field of astrophysics. 1974 – First binary p...

Managing ChatGPT's Chat Logs

-
Throughout this blog I share some of the conversations I have with ChatGPT, but I'd gotten out of the routine and amassed a long list of conversations - this list was also difficult to make a copy of. In addition to this, ChatGPT was providing no up-front "date of conversation" information; two things that were hindering my desire to get back on track. ChatGPT informed me "You can view exact timestamps if you export your ChatGPT data..." so: Step 1: Export your ChatGPT chat data: Go to Settings → Data controls Choose Export data You’ll get a ZIP file by email [the link to download arrived within a few minutes in my case, the file contains everything, including created and shared images, so it can be pretty large]. Inside it ... [you will find] the file: conversations.json [mine was 20MB, spanning some 700~ conversations...] Each conversation includes fields such as... UNIX timestamps [which] can be converted into exact human-readable dates.   Step 2: Extract th...

Ancient Gatways

-
  Many ancient sites around the world have been described or interpreted as "gates," "gateways," or "portals" , either in a literal, symbolic, or metaphysical sense. These labels are often rooted in myth, religious belief, architectural function, or modern speculative interpretations. Here's a breakdown of what this can mean: 🔹 1. Literal and Functional Gates In ancient times, city gates or monumental entrances were real, physical structures that regulated access and often held ceremonial or political significance . Ishtar Gate (Babylon, Iraq) : A massive ceremonial gate to the inner city of Babylon, dedicated to the goddess Ishtar. It was richly decorated and symbolized the city's grandeur and divine favor. Lion Gate (Mycenae, Greece) : This was the main entrance to the fortified city of Mycenae and featured a symbolic relief sculpture. It functioned as a literal threshold but also conveyed authority and divine protection. 🔹 2. Symbol...

Reduced sunlight leads to reduced levels of Vitamin D

-
 I believe reduced sunlight leads to reduced levels of Vitamin D production in the body. In less sunny regions like the United Kingdom this can, it seems, pose health issues. Can you expand on this and postulate as to the effects of reducing the sunlight, even slightly, such as through increased cloud-cover?   You're absolutely right that reduced sunlight can lead to lower levels of vitamin D production in the body. Here's a deeper look into this, especially in the context of regions like the UK, and what might happen if sunlight levels were reduced even more due to increased cloud cover: Vitamin D and Sunlight: The Connection Vitamin D Synthesis : The primary natural source of vitamin D is its synthesis in the skin through exposure to UVB rays from sunlight. When UVB rays strike the skin, they convert a cholesterol derivative into vitamin D3 (cholecalciferol), which the liver and kidneys then process into its active form. Latitude and Season : In higher latitudes like t...

Mouths, eyes, ears, nose...

Where in the Bible is this statement from? "they have eyes but they do not see ears and they do not hear" ChatGPT: The statement "they have eyes but they do not see, ears but they do not hear" appears multiple times in the Bible, often in slightly different forms. It is a recurring theme to describe people who are spiritually unresponsive despite having the faculties to perceive truth. Here are a few key references: Psalm 115:5-6 (NIV) "They have mouths, but cannot speak, eyes, but cannot see. They have ears, but cannot hear, noses, but cannot smell." Isaiah 6:9-10 "He said, 'Go and tell this people: "Be ever hearing, but never understanding; be ever seeing, but never perceiving." Make the heart of this people calloused; make their ears dull and close their eyes.'" Jeremiah 5:21 "Hear this, you foolish and senseless people, who have eyes but do not see, who have ears but do not hear." Ezekiel 12:2 "So...
