🔬 The Science of Fasting Where Ancient Siddha Wisdom Meets Modern Nobel Prize Research 🌿 Introduction What if the secrets of cutting-edge science were already known thousands of years ago? Imagine a Tamil Siddha meditating in a mountain cave and a modern scientist observing cells through a microscope—both arriving at the same truth. In 2016, Yoshinori Ohsumi won the Nobel Prize for discovering Autophagy , a cellular self-cleaning process. Yet, this concept mirrors the ancient Siddha practice of fasting, known as Lankanam . This blog explores how fasting is not starvation—but a powerful internal healing mechanism , almost like performing “surgery” without a scalpel. 🔥 1. Two Perspectives: Jatharagni vs. Autophagy 🪔 The Siddha View: Burning “Amam” In Siddha philosophy, health revolves around Jatharagni —the digestive fire. Constant eating = dumping wet wood into fire Weak digestion = formation of Amam (toxins) These toxins accumulate in joints and organs → disease 👉 When you fast, ...
Time is one of humanity’s oldest obsessions. From the rising sun to the ticking of modern atomic clocks, our journey of measuring and mastering time reflects both scientific progress and cultural change. Let’s take a journey through history to see how humans learned to keep track of the hours.
🌞 Sundials – The First Shadows of Time
The earliest timekeepers were sundials, dating back to ancient Egypt around 1500 BCE. By observing the shadow cast by a stick or pillar, people could divide the day into segments.
-
Strength: Simple and effective in sunny regions.
-
Limitation: Useless at night or on cloudy days.
⏳ Water Clocks and Sandglasses – Time in Flow
Civilizations like the Egyptians, Greeks, and Chinese developed water clocks (clepsydra) to measure time by the steady flow of water. Similarly, sandglasses measured intervals with falling grains of sand.
-
Strength: Worked without sunlight.
-
Limitation: Needed constant refilling and not very precise.
🕰️ Mechanical Clocks – The Middle Ages’ Marvel
By the 14th century, mechanical clocks appeared in Europe, powered by gears, weights, and escapements. Tower clocks in town squares not only marked the hours but also symbolized civic pride.
-
Innovation: Public timekeeping became possible.
-
Impact: Shifted societies toward scheduled work and daily routines.
⌚ Pendulum and Precision – The Age of Accuracy
In 1656, Christiaan Huygens invented the pendulum clock, vastly improving accuracy—down to seconds per day.

Result: Reliable navigation at sea became possible with marine chronometers.
-
Legacy: Set the stage for scientific revolutions, commerce, and global exploration.
🔋 Quartz Clocks – Electricity Meets Time
By the 20th century, the invention of quartz crystal clocks brought even greater precision. Quartz vibrations provided steady oscillations, accurate to within a few seconds per year.
-
Everyday Use: Wristwatches, wall clocks, and early computers relied on quartz timing.
⚛️ Atomic Clocks – Splitting Seconds
The modern era of timekeeping began in 1949 with the first atomic clock, using vibrations of cesium atoms.
-
Accuracy: Atomic clocks lose only one second in millions of years.
-
Applications: GPS navigation, global communications, astronomy, and defining the official “second” in the International System of Units (SI).
🕰️ Conclusion
From sun shadows to atomic vibrations, the story of timekeeping mirrors our pursuit of order, knowledge, and progress. Each innovation didn’t just measure time—it shaped civilization itself, guiding how we live, work, and connect.
