From early beginnings in the womb until the late stages of adulthood, music plays an important role in human growth, development, and sustainment.  Music— to be defined here as organized sound— is an essential component of most cultures, coloring the world through melodies, harmonies, rhythm, and lyrics.  Humans use music as a form of emotional expression, as well as a group bonding activity through participation in orchestras, bands, and casual gatherings.  Most recently, psychological researchers have been interested to find that music has another, potentially even more important function: it can improve brain development.  In several experiments conducted regarding this phenomenon, statistics show that children who play instruments and possess the ability to read music tend to score higher on achievement tests (Costa-Giomi, 1999).  Also, brains of adult musicians are significantly different in structure and function than those of non-musicians (Schlaug, Nor...

A signal caused by the very first stars to form in the universe has been picked up by a tiny but highly specialised radio telescope in the remote Western Australian desert. Details of the detection are revealed in a paper  published today in Nature  and tell us these stars formed only 180 million years after the Big Bang. It’s potentially one of the most exciting astronomical discoveries of the decade. A  second Nature paper out today  links the finding to possibly the first detected evidence that dark matter, thought to make up much of the universe, might interact with ordinary atoms. Tuning in to the signal This discovery was made by a small radio antenna operating in the band of 50-100Mhz, which overlaps some well known FM radio stations (which is why the telescope is located in the remote WA desert). What has been detected is the absorption of light by neutral atomic hydrogen gas, which filled the early universe after it cooled down from the hot...

Hey there I am back with one more interesting question. WHAT WOULD HAPPEN IF BLACK HOLES TRAVEL AT SPEED OF LIGHT? Black holes are one of the most interesting part of cosmology…...and that’s the point to make me wonder this incredible question…... Now this will be a bit longer and thus it may be in parts and I am not sure… First of all, black holes are great! They are incredible in terms of eating and thus get heavier as they grow. They eat almost anything they see. Black holes are bodies with extreme densities and mass … As per Einstein space time fabric just curves with massive objects as we see in the case of black holes almost everything just atomise and they revolve around event horizon…. Since matter atomise and the time dilates just from a stationary black hole what will be effects of its moving and just think of motion at speed of light…. Anything traveling at that speed have a major impact on surroundings and on itself.   The effects of speed...

Hey there, today I will be discussing how actually brain stores information. So, let’s start!! Before knowing how does brain stores information we need to know certain terms: 1.) Neurons: These are data cables of our large computer like body or any organism’s body. They transfer data from one part of body to another part in form of electrical impulses. Whenever we see, listen, speak, learn, think we actually generate electrical signals in neurons that transfers data from one end to other. 2.) Synapses: Actually, none of the neurons are large enough to directly connect, even our eyes to brain so they require to be connected to other neurons at junctions known as synapse. It’s little odd but neurons are connected by “ gaps ” known as synaptical gap. They are filled with electrolytes and proteins to connect neurons efficiently. So, actually we can now start … Encoding memory to...

Hey there this is Sci Tech Revel  and today I'll be giving you some best sci-fi movie' list to watch this weekend. Though I don't promote piracy  but you can still download them using torrent. My Top Ten Best Sci-Fi Movies Battleship  – I just posted a review for this last night. Serenity  – They should have never canceled Firefly, but I’m extremely happy to have Serenity in my life. The Fifth Element  – To this day, and to the continual puzzlement of my daughter, I still randomly exclaim “Big Ba-Da Boom!” I just tell her she’ll understand when she’s older. Starship Troopers  – So bad it’s good. Gigantic bugs. Lots of mindless action. A then-hot Casper Van Dien. ‘Nuff said. Independence Day  – Okay, I’m just blantantly going to ignore the sequel exists. Independence Day is THE mindlessly fun, action-packed popcorn and adult beverages sci-fi movie. District 9   – Unusual take on aliens, and watching your average Joe get  ...

Hey there this is SciTech Revel.!! This post will discuss about why CPU and GPU processor needs to be maintained for better performance. Actually, this is to deal with interior of CPU and GPU. What are they made up of? Answer to this is really simple that is they are generally made up of silicon or germanium transistors which are semiconductors i.e. they conduct electricity partially. Now, the answer to main question is nothing to do with computing, it is basically pure physics, particularly electrodynamics. Now how does any conductor conduct electricity? Into the metal at atomic level displaced kernel electrons are drifted from one end to other due to potential difference across the ends of the conductor. Now as electrons drift from one end to other they pass through the gap of metal kernels, as they pass through metal kernels they kind of interact with the positive kernels. Thus, more is the interaction less is their velocity and in turn lesser is the conductance . As ...

Black holes, quasars and active galaxies The disk of dust and gas accreting around a 300 million solar-mass black hole in NGC 7052. Black holes are objects so dense, and with so much mass, that even light cannot escape their gravity. The existence of black holes has been theorised for more than 200 years. It is impossible to observe them directly, and astronomers had no way to test their theories until Hubble arrived. The high resolution of Hubble made it possible to see the effects of the gravitational attraction of some of these objects on their surroundings. Hubble has also proved that super massive black holes are most  likely present at the centres of most, if not all, large galaxies . This has important implications for the theories of galaxy formation and evolution. Black holes exist in different sizes. Stellar black holes, which are around the mass of our Sun, form when very large stars explode as supernovae at the end of their lives. The star's core collapses...

Hey there this is Sci Tech Revel.. Before heading You may  want to know more about GPUs . If you are done with it I'll try to tell you in brief that why Machine Learning or Deep Learning Require GPUs for  better performance. Actually the process is motivated by process of real learning which uses synapses to store data on human brain and think. Similarly machine's brain uses processor links to store data processing algorithm.When a machine learning enabled program is loaded on the system then programs loads neural network on the processor to think rationally. So when whole complex neural network is loaded it will require a number of cores to process data on the neural network. A CPU possess a small no. of cores to load neural network effectively, but a GPU will have many cores to use  thus neural networks are loaded effectively on the GPU so effective data processing is possible. Thus GPU is required by a machine learning program to work effectively.

                   BEST SCIENCE BOOKS TO READ:- "What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic."  - Carl Sagan So here I am going to provide you 20 best science books to read....
