Plant absorbing sunlight for photosynthesis

CARBS Explained: The Science Behind Our Food

Photosynthesis for plants is a little bit like if, as a human, you could just lay in the sun on a nice afternoon and create, directly in your stomach, a creamy lentil soup or a sandwich of your choice. Hello everyone and welcome to The Unseen Threads! I’m Saikat, a normal guy obsessed with helping you understand science and make you fall in love with it. Today, I am going to discuss how these little plants 🪴🌱 are made, where they come from, and why you should absolutely care because it has everything to do with carbs. So, let’s get started.

The Fascinating Rhythm of Human Sleep and Earth’s Light

The Global Sleep Cycle It’s 3:00 in the afternoon here in Los Angeles, and you know what that means—Big Sleep time. Right now, most humans living on planet Earth are asleep. It’s the crack of dawn in China, and it’s midnight in Paris. As much as 70%, maybe even 80%, of the humans alive on this planet right now are asleep. Sleep Patterns Across the Globe Within the United States, the time when the most people are asleep is midnight in Los Angeles. At that time, only about 22 million people in the contiguous U.S. say they’re usually awake. This sleep pattern illustrates the fascinating rhythm of human rest spread

Will We Have a 25-Hour day?

Will We Have a 25-Hour Day? I am a very lazy kind of guy… So when I see people getting so many things done in one day, I just think: do they have more time in a day than me? Well, now it seems like some people will have more time than me in a day… It’s hard to imagine, but the length of each day on Earth hasn’t always been 24 hours. Though most of us don’t notice, the length of our days has been changing slowly over millions of years. Scientists have discovered these changes and understand them in great detail. Let’s take a journey through time to

Rethinking Energy

I spend a lot of time thinking about how we can better our planet, and recently, I have been seeing some talk about energy and a major shift in how we view our energy future. To fix our current energy problem, we often revolve around the need to reduce energy consumption, to live more frugally, and to brace ourselves for a less comfortable future. Spoiler alert: It’s not about using less energy but about generating more – and making it all clean. Let me take you through my thought process and why this change in perspective is crucial for a sustainable and prosperous future. The Traditional Energy Narrative Growing up,

Inflation: Understanding the Economic Necessity

I have never been a fan of economic news, so I don’t have much knowledge about any of it. But I do know one thing about our economy: whenever inflation goes up, our life gets a little more complicated, and if it goes really up, then we tend to get into big trouble. The trouble we usually get into is prices getting too much out of hand and many of us suffering from it. But as I was writing this blog, I did a lot of digging and tried to understand how and why inflation happens and why it is so complicated. I have tried to write it down as

Terrifying Science of Avalanches

Avalanches are one of nature’s most terrifying and awe-inspiring phenomena. These powerful snow slides can occur with little warning, causing devastation and sometimes even taking lives. Understanding avalanches—what they are, what causes them, and how to stay safe—is crucial for anyone venturing into mountainous terrain during winter. What is an Avalanche? An avalanche happens when a lot of snow slides rapidly down a slope together. This happens for a lot of reasons, including changes in the snowpack, weather conditions, or even human activity. Avalanches are categorized by size on a scale from one to five, with size one being relatively harmless and size five involving 100,000 cubic meters of snow

Exploring the True Danger!

When we look at the dangers of our planet, our minds often wander to extreme climates, treacherous landscapes, or deadly creatures. Yet, the true dangers of Earth extend far beyond what meets the eye. 93% of all humans who have ever lived are dead. For every person alive right now, there are 15 people who are no longer alive. The Earth is dangerous… To understand it, we need to delve into statistics, historical events, and environmental disasters, uncovering a tapestry of danger that spans from microscopic threats to human-made catastrophes. Temperature Let’s begin with temperature… Extreme heat and extreme cold can kill within hours if not minutes. In cold environments,

Unraveling the Flat Earth Mystery

We have all heard of the flat earth theory at least once in our lives. Maybe even wondered ourselves if the earth is flat or not… Well, today let’s talk about that and understand the mystery ourselves… It’s really easy to understand that the earth is round because there are so many ways to prove it… For example, we can look at a boat on the horizon and we will see the bottom will be the first thing to disappear, which proves that the earth is round… or even if we look at the moon, you will see that during a lunar eclipse, the shadow of the earth on the

How Does Earth Actually Move? 

If asked, most of us will agree that the earth moves in two ways:   1. On its axis (axis is an imaginary line that goes through the North and South Poles). 2. Around the sun.   But before we can say that, we need to raise the question: how do we even measure this movement? If we need to measure anything’s true movement, we need to have a relative point. So depending on where we observe the movement from, Earth moves differently. To understand this better, think if you were in a bus and you are moving in a circle inside the bus. Depending on how someone looks, you
