 What is the difference between a jet airplane engine and a rocket? November 2002 In our September column, we explained how a rocket works in space where there's no air. People generally believe that a rocket must press on air so as to propel the rocket forward, but that's not the case. Briefly stated, a rocket works because of Newton’s third law, which says for every action there is an equal, and opposite reaction. The burning of fuel creates gases at high , which exit from the exhaust nozzle and push the rocket forward. As gases exit the rocket, a reaction force (thrust) pushes on the rocket making it proceed . The faster the gases are expelled from the rocket, the greater the thrust. Think of how a hose creates a force pushing back on the hose as water squirts from it. In fact, jet engines and rockets operate an equivalent general physics principle. Both eject fuel out the back. The momentum imparted to the present exhaust is adequate to the momentum gained by the vehicle, t...

 How to slow ageing? This may sound funny at first but actually it is not. Today we'll discuss the methods of slowing down the aging process biologically and also discuss about better understanding off why do we age? In order to know how to slow down the aging process we must know what is ageing. Ageing can be defined as getting older in normal terms .Technically aging means change in function and structure of an organism with the time passed. But is it you who is aging or your structural body? Your body maybe only a framework For your conscious brain. Since information can be used when you are conscious when your brain is conscious. So what does it means to age if it were only to  about functions and structure? Aging is possible when our brain provides information to cells and that happens when you are conscious. So why loss of consciousness results death? Consciousness can be stored and later cloned so what's the point of aging?  Moon jellyfish is a type of jellyfish wh...

 We homosapiens have come a long way from hunting animals with woods and stones , to developing self driving cars. While we're at the age of information everything might change in few years . Technology we didn't expect today a will be  common tomorrow. Here is the list of of some  inventions that we might to witness in few years.   Technology in the future within 2050. A lot of changes will come within 3 decades from now . Some of them being greatest thing ever to be invented . No 1, nano technology:  literally nano means "one - billionth". It may take more decades to develop a functional nano robot, but yes it is possible to make a robot that can at least fix the wounds in the artery without any type of surgery within 2050 . The nanotechnology will reduce the cost of of big surgeries with less side effects and will be helpful for  several other works that is at microscopic level. Nanotechnology e can be used for every field including physics, chemist...

 "Fish fish queen of river, But she's ain't gonna live there forever". Ever heard about fish walk on land ?or may be even breathe air . Why did they come to land ? Isn't there any other place to go ? Or may be they're bored of water and decided to take a sun bath. Today we're going to cover these following topics :  No1, walking fish. No2,walking fishes names. No3,Is there any fish with legs? No4, why fishes come to land? No5,Do they really come to take sunbath? No6,snakehead fishes(for next blog). No1,walking fish . In literal form walking fish means fish that can walk on land or stay at land for over extended periods of time.For instance :mudskippers. These mudskippers can spend as much as 90% of their time on land rather than water. Normally fishes have gills to breathe which is covered by overlapping layers of skin under that skin layers lies capillaries that takes in dissolved oxygen from water. While they are out of water their gills collapse resulti...

 There are several mysteries unheard, unsolved and are unexplainable. Some might be true and proved by science but millions other questions still remains unanswered till date. Same goes for the legendary mystery of mount kailash. There are thousands of myth regarding this holy mountain. Some spread false beliefs and some are proven by science and alot is yet to be solved. No,1:No one has ever conquered the peak of mt. Kailash. It's not the tallest mountain but yet no one has ever been able to reach it's peak. It's not that no one ever tried to climb it but every one who tried to climb it failed miserably. The mountaineers say that whenever they try to climb the mountain , all of a sudden a storm out of nowhere. Some say that they suffered from heart pain all of a sudden and often caught cold. No,2: It's shape and geology. It is four  sided, identical to a pyramid. And science had proven that pyramids emits energy. Scientists from both Russia and America believe  th...

Nature is full of surprises, whether from land, to the seas , deep down the mysterious oceans to dark caves . Human's curiosity is there key to know such mysteries of nature but, space is far beyond any rules, from Black holes to dark matter or to our very own star the sun. We were created by a star we live because of this star and we will die along with this star. We will continue to learn adapt and live, but for how long? So , here are 5 shocking FACTS about space that will give you chills. No,5:separating moon .      The moon, theorists say it was originated from the Earth due to a collision with a planet , the size of Mars , about 4.5 billon years ago, this is also known as Giant Impact Hypothesis. The moon is moving farther from the Earth are there rate of 4cm each year because of tidal interaction. This may sound less but after few thousands millenniums you'll never get to see solar eclipse nor lunar eclipse. There will be no tides and 1 day will be equal to one mon...

14 facts about Human body that you must know. Our world is full of surprises and unexplored things . From the tiniest living being to the largest whale , it is complex to figure out how nature actually works . Day by day ,a new thing gets discovered . whatever we know now, it is just a  minute part of vast ocean of knowledge. As much we might know about the world right now , scientists have discovered several facts about human body but some are still left to be explored. Here are few facts about human body . No,1:   Our brains are powerful enough to light a bulb. ~                      Our brains can generate electricity for about 15 to 20 watts (Roughly 0.085 w).This happens as a result from the motion of sodium , and potassium ions across the cell membrane. Through axon to the synapse , these electrical signals help to transform information . No,2: Roughly human teeth are as strong as shark's teeth.  That is because...
