Interesting Facts about Human Brain

◖The brain of a human carries nearly one hundred billion neurons.

◖An adult brain weighs about 3 pounds.

◖Your brain consumes 20 percent of the oxygen and blood in your body.
◖The human brain gets to be smaller as we get older. This happens after the middle age.

◖About 75 percent of the brain, is manufactured with water. This means that dehydration, even in small amounts, harms the brain functions.

◖Headaches are triggered by a chemical reaction in your brain, communal with the muscles and nerves of your neck and head.

◖Dreams are supposed to be a mixture of imagination, psychological factors, and neurological factors. They prove that your brain is at work even when you are sleeping.

◖Your brain isn’t fully formed until age 25. Brain development begins from the back of the brain and works its way to the front. Therefore, your frontal lobes, which control planning and reasoning, are the last to strengthen the structure connections.

◖Computer or video games may assist to boost cognitive abilities.

◖Your brain is bored easily. Research has found that every 10 minutes you need something that sparks you emotionally to hit the reset button on your attention. If that 10-minute number sounds long, it’s because the human attention span (how long you can pay attention to a single thing) continues to shrink.

The human brain, weighing about 3 pounds and made up of nearly 100 billion neurons, is a highly complex organ that consumes around 20% of the body’s oxygen and blood. Composed of about 75% water, it is sensitive to dehydration, which can impair its functions. Brain development continues until around age 25, with the frontal lobes—the center for planning and reasoning—maturing last. Over time, especially after middle age, the brain gradually shrinks. Despite resting states like sleep, the brain remains active, producing dreams shaped by imagination and neurological factors. It can be influenced positively by activities such as video games that enhance cognition, but it also gets bored easily, with research showing that attention often needs an emotional “reset” about every 10 minutes. Headaches, meanwhile, arise from complex interactions between chemicals, nerves, and muscles in the head and neck.

Neutron stars

Neutron stars are the densest objects in the entire universe. They're so dense, in fact, that if they were even a tiny bit denser, they would collapse to become black holes. Neutrons stars are what you get after a giant star (at least 10 times the mass of the Sun) dies. The typical density of neutron stars is around 10^17 kilograms per cubic meter. A thimbleful of neutron star material would weigh more than 100 million tons on the surface of Earth. It is this incredible density that is able to compress neutrons into cube-like shapes. Neutron stars are one of the most fascinating and extreme objects in the universe, formed from the remnants of massive stars that have undergone a supernova explosion. When a star about 8–20 times the mass of our Sun reaches the end of its life, its core collapses under gravity after exhausting its nuclear fuel. The outer layers are blown away in a spectacular supernova, while the dense core is crushed into a neutron star. This collapse forces proton...

Sonam Wangchuk

Sonam Wangchuk (born 1 September 1966) is an Indian engineer, innovator and education reformist. He is the founding-director of the Students' Educational and Cultural Movement of Ladakh (SECMOL), which was founded in 1988 by a group of students who had been in his own words, the 'victims' of an alien education system foisted on Ladakh. He is also known for designing the SECMOL campus that runs on solar energy and uses no fossil fuels for cooking, lighting or heating. Wangchuk was instrumental in the launch of Operation New Hope in 1994, a collaboration of government, village communities and the civil society to bring reforms in the government school system. He invented the Ice Stupa technique that creates artificial glaciers, used for storing winter water in form of conical shaped ice heap. Wangchuk was born in 1966 in Uleytokpo, near Alchi in the Leh district of Ladakh. He was not enrolled in a...

Indira Gandhi

Indira Gandhi, the second from her lineage to have wielded the position of Head of State, is the only woman to have been elected as the Prime Minister in India to date.

Born into a family of freedom fighters and political leaders, her entire life was spent in the realm of politics. Indira Gandhi boasted an illustrious educational background. She studied at some of the most prominent institutions, both domestic and foreign. Her academic years were spent at Ecole Nouvelle, Bex (Switzerland), Ecole Internationale in Geneva, Pupils’ Own School in Pune and Mumbai, Badminton School in Bristol, Vishwa Bharati, Shantiniketan and Somerville College of Oxford University. She became inquisitive about p...
