   Free Flow of Electrons!   Electrons are the building blocks of electronic devices and the movement of these electrons plays a crucial role in the functionality of electronic devices. Basically, any electronic conduction requires the movement of electrons and thus it is a very fundamental and important aspect. In traditional metals, electrons are expected to move diffusively, meaning that they behave like individual particles. However, a recent study has discovered a novel behaviour of electrons in a metal called ditetrelide (NbGe2), where electrons behave like a fluid, flowing in a way similar to water in a pipe. This fluid-like behaviour is due to the interaction between electrons and quasiparticles called phonons, which arise from vibrations in the crystal structure of the metal.     This discovery has important implications for the development of new electronic devices as it completely revolutionaries electrical conduction. Let's first look at the traditio...

                       THE SEVEN WONDER'S OF INDIA The 2021 Tokyo Olympics , now you will be thinking why I am talking about Olympics now ,but in these two years not only we had forgotten about medals but also the stars of Olympic 2021. So, let’s revive the 2021 again.  The 2021 Tokyo Olympics was a historic event for India, as the country witnessed its greatest ever medal haul at the Olympics. The Indian athletes put up a spectacular performance, winning a total of seven medals, including one gold, two silver, and four bronze. The Indian contingent's performance was a source of inspiration for millions of people in the country, and it showcased the immense potential of Indian sports. The Indian athletes who won medals at the Olympics were the pride of the nation, and their remarkable achievements have made them heroes in the eyes of millions of people. Let's take a look at some of the Indian Olympic stars who inspired us ...

                               You've  probably heard the rumor that you can't sneeze with your eyes open because your eyes will pop out if you do. Is it impossible to sneeze with your eyes open? Let's find out in today's blog.   You've probably noticed that whenever you sneeze, your eyes automatically close right before you sneeze; most of us learn this eye-popping rumor, and honestly, and luckily it's a myth, your eyes will definitely not pop out.  Fear not, fellow sneezers! The act of sneezing — also known as sternutation — will not cause your eyes to pop out, even if you do sneeze with your eyes open.  If you sneeze, your eyes close just before a sneeze as an involuntary reflex; the brain sends a signal to the eye muscles telling them to close without you ever having to think about it. But why do our eyes automatically close? Experts can't say for sure, but many believe it c...

   FLICK, PULSE AND SUPERCONDUCT   WHAT IS SUPERCONDUCTIVITY?   By definition, superconductivity is  a state of matter that has no electrical resistance and does not allow magnetic fields to penetrate. For regular conductors, as we know, resistance decreases linearly with temperature and becomes 0 at absolute temperature (0 Kelvin). However, in the case of superconductors, they have a critical temperature — based on their physical properties — below which their resistance drops to 0 ohms. Now, superconductors are of great influence due to their properties and hence find multitudes of applications. However, this also makes them expensive and difficult to obtain.   Graphene, an allotrope of carbon (which is more accessible than currently available superconductors) also acts as a superconductor. However, there is a twist (pun intended). Source: www.maxpixel.net MOIRÉ SUPERLATTICE   Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal...

 Breaking the Glass Ceiling: A look at inspiring women who changed the world Image Source: Jagran Josh On March 8th every year, we celebrate International Women's Day, a day dedicated to honouring the social, economic, cultural, and political accomplishments of women. Each year, it has a different theme, and the theme for IWD 2023 is #EmbraceEquity. Women have made tremendous strides in the last century, but we still have a long way to go to achieve true equality. Women are an integral part of society and have made significant contributions in every field. Despite facing numerous challenges and obstacles, women have persevered and shattered the glass ceiling to make a name for themselves. Despite many challenges, women have made tremendous progress over the last century. Women are breaking barriers and achieving new heights in every field, from politics to science to the arts. Women have made ground-breaking contributions to science, literature, art, and politics. Marie Curie, the ...

  Do you know what edge computing is? Although it may seem like a difficult and technical idea, it's actually quite cool. Imagine having complete access to all of your data and programs without the requirement of a central hub. Edge computing is all about doing that! Now, I know what you're thinking. "But wait, isn't that what the cloud is for? "  Yes, the cloud is great for many things, but edge computing takes things to a whole new level. Instead of relying on a single server or data center, edge computing allows for processing and storage to occur closer to the devices that need it, such as your smartphone or smartwatch. This means faster response times, less latency, and a more seamless experience overall.                             But let's slow things down a bit and take a closer look at how edge computing works. Imagine you're at a concert, and you want to take a video of your favourite song. You pu...
