Nuclear Fusion - Energy of the future

-


"Energy can neither be created nor be destroyed but can be converted from one form to another" Of course. We get energy from various sources, the common ones being thermal and Hydel power. The newer sources being geothermal, wind and solar energy. While all the above are quite earthly, the latest entry, "Nuclear Power" holds some unearthly possibilities.

 Nuclear Energy is basically obtained by modifying the nuclear structure. It involves fusion or fission of nuclei. The current nuclear power plants function on the "Fission" concept by separating a heavy nucleus (generally Uranium) into lighter nuclei.

 Thinking of "Fusion" leads to the unearthly side of nuclear energy. It is a very common occurrence in stars like sun, generally at temperatures of around 100 million ℃ . 
Nuclear Fusion can give 11000 times more energy than burning coal. And the extreme reaction cannot be controlled in any reactor,made of ANY element. It is expected to be controlled by extremely strong Magnetic fields. 
Nuclear Fusion also appears safer, as there is no possibility of damage due to uncontrolled chain reaction as in the case of Fission. Once the setup fails, the reaction should stop abruptly, since the temperature will not be sufficient for further reaction. It is also expected to generate less radioactive waste.

 Amazing Fact : Sun converts on an average 500 million tonnes of hydrogen into helium every second!

    Hmmmm. Sounds interesting. nuclear energy... The word itself makes me scary and I feel unsafe about it. Just my thoughts about it. But now.. nuclear fusion is much efficient and safe ofcourse. But the principle is magnetic field. Imagine.. what if the reaction goes uncontrolled.. meaning it goes beyond a threshold and starts sucking up al objects showing magnetic property...it would be a huge catastrophic.. And mean that molecule would get bigger and bigger..and the power of magnetism Wil increase further more sucking the objects at a particular radii..making it difficult to stop. Dats dangerous..well it can happen.

    Well, the nice thing about a fusion reaction is that if somehow it would go out of control, as you had told, if it goes beyond a threshold and starts sucking up all subjects showing magnetic property, it would just stop itself automatically. If a fission reaction goes out of control, it can really go out of control, you can't actually stop it and it might actually go into a nuclear meltdown.

UNDERSTANDING AN ADOLESCENT'S BRAIN- IS IT ACTUALLY SIMPLE?

Image Source: https://movingscience.dk/infographic-about-the-adolescent-brain-development/ It really doesn't matter how smart an adolescent is, or how well they scored in NEET/JEE/SAT or whatever. Adolescence is a remarkable phase of human development, often marked by a unique blend of curiosity and self-discovery. I know it's been really long since I have posted here, and one of my friends wanted me to write on how an adolescent's brain behaves so distinctly compared to kids and adults- and so this is for her and for everyone else sitting with their curious caps on! The adolescent brain is a dynamic landscape of neuroplasticity, where synapses are pruned and rewired to optimize cognitive function. This plasticity not only facilitates learning, but also paves the way for development of higher-order thinking and decision making. A rapid increase in the connections between the brain cells also occurs, which makes the neural pathways more effective.  For both boys and girls, a

CAN TWO EGGS BE FERTILISED TO FORM A ZYGOTE?

  So, one of my friends asked me this brilliant curious question one day - Instead of a sperm fertilising an egg, can an egg fertilise another egg? So, this post is mainly for her and many other inquisitive people out there wondering similar things. I have been having so many thoughts on this and the following is a small gist of my thoughts penned down.  So let's say one were to take an egg, insert the DNA from another egg, and then insert centrosomes from another cell, is it possible for the cell to divide? Well, probably we might have to give it a mild electric shock. This is what is done in some cloning techniques. I mean, of course, there is no guarantee that this method is bound to work, but probably it might work?  Replication can be done in the lab too but the issue is that there is not much understanding about gene regulation and reproduction. Most of us know about Dolly, the sheep which was the first mammal to be cloned, using the diploid nucleus from an adult tissue. Here

DOES MUSIC MOVE YOU? HERE'S THE ACTUAL REASON WHY IT HAPPENS!

Source: https://www.researchgate.net/figure/Recognition-of-music-in-brain_fig1_357920499 For most of us here, music is something that simply makes our life better. For all the music lovers, this post is especially for you all! Imagine a day without music- a world where melodies don't grace our ears, and rhythms don't resonate within our souls. From the soothing cadence of a lullaby to the pulsating beats of an adrenaline-filled anthem, music has an unparalleled ability to mold our emotional landscapes and shape our mental well-being. Even some nearly non-communicative people with Alzheimer's disease sing along and engage in conversations when the music they have listened to the most, during their childhood days, is played.  Let's actually explore the reason why and how music moves us so much! When you listen to music, it is basically like a power-up for your brain! It's like a surge of energy zipping through your mind. When you tune in, your brain gets a boost- the
