 In the latest launch event held by Apple on 11th November 2020, they have announced the new Silicon processor for Mac line-ups such as Macbook and iMac. Silicon processors have been developed for decades and been used for their Tablets, Watches, and Smartphones. Earlier this year, they have announced to cut ties with Intel - which was the processor they have been using for its Pc line-ups previously and make their own processors for the average workload done by an average OSX user. Silicon chips usually co consume less power and still outputs incredible performances.  The Silicon chips which will be specifically used in Macs are called the "M1". Usually, every computer has its RAMs, GPUs, I/O, separately. But M1 unifies all those components into one set. The Unified memory architecture provides High Bandwidth of data transfer as fast as possible and access to the entire SoC. This is also the first CPU to use 5nm transistors (While AMD  uses 7nm). "M1" has 16 bill...

Cosmic Physics   Though it has started recently, it's best for cosmic enthusiasts. It is well written and frequently posted.   World Science U This website contains lectures by famous physicists. One of the best course is Special Relativity by Brian Greene. See The Elegant Universe By Brian Greene to know more.   Khan Academy - High School You would have all known Khan Academy. It is the best online tool for school children. If you have begun physics and don't know the basics yet, this is the right place to start!     Phys.org Phys.org are updated frequently, so contains up to date news.   The Institute of Physics The official blog of IOP (the Institute of Physics) is a discussion about advancing physics for the benefit of all.

I just finished reading Brian Greene's  The Elegant Universe ! For starters, this is one of few physics books which got New York Times Bestseller .  Brian Greene explains the unintuitive  String Theory , such that even an average person would understand!   STRING THEORY String theory is an attempt to unify all the laws of physics into a single equation. String theory also tries to join  quantum mechanics and the general theory of relativity , which gets divided by zero (which is impossible in math and physics) when we try to join them together!   Let's see the contents of the book. SPECIAL THEORY OF RELATIVITY  Before starting String theory, we should know why we need String theory. So, Brian starts with teaching relativity. This theory says that time flows differently for two objects moving at different speeds. GENERAL THEORY OF RELATIVITY The general theory of relativity says that gravity is just the bending of spacetime. It also says that time f...

In our recent blog, we talked about the launch event of the  AMD 5000 Series . We have mentioned the Radeon 6000 Series GPUs and their launch event. And today is the day. Radeon RX 6000 Series will be unveiled today live [28-10-2020 21:30 IST]. We will be covering the features of the also-known Big Navi. As always CEO of AMD introduced the new product. Laura Smith, Senior Director of Radeon Technologies, covered features of the RDNA 2 architecture and the  GPU. They have developed twice since the RDNA 1. This processor is based on a 7nm die. This GPU has 2.17X of Bandwidth with the help of its new Infinity Cache.

  There are about 5 lakh debris or space junk orbiting our planet at a speed of 28000 km/h! This issue is a rising problem for space stations and institutions. Their velocity is very fast, such that it can go through and damage satellites and spacecraft. WHAT ARE THESE SPACE JUNK These space junk consists mostly of synthetic materials but also some debris of meteoroids. The artificial junks are the unused or dead spacecraft, launch vehicle stages and mission-related debris. There is about 2 lakh debris that outsizes a softball, capable of damaging anything that comes in their way. EVENTS 1996:  a French satellite was damaged due to the explosion of Fench rocket which occurred a decade earlier. February 10, 2009:  a disused Russian spacecraft collided and ruined a functioning a US Iridium telescope. It added more than 2000 debris to the orbit! 2007:  China used missiles to destroy an old weather satellite, adding more than 3000 debris. HOW TO AVOID HITTING BY A DEBR...

"Chandrasekhar!" a robotic voice proclaimed "Yes, sir!" replied Chandrasekhar. "Go for undocking!" In the next five minutes was the perspiring moment for the astronauts.  "Telecom Go!" proclaimed the speaker. The Majestic  flew over up in a high velocity and pitched up to slow down the  Majestic.  It landed like a helicopter safely and soundly. The last "Go!" was yelled, and the door fell. Soon, Subramanyam will be the first man to land on  Planet Hypatia,  maybe the next Earth! Physicists Raman and Chein-Shiung Wu were on a shuttle revolving Hypatia . Dr Sivan told it was the best place to check on  Aries binary stars.  They kept the telescope ready, to reason out the anomaly that has driven astrophysicists crazy!  Wu scoped through the  Aries A  star and noticed the  B star.  Raman checked the final image, which has colour codings according to the elements present. The results shocked the scientists. It was nothing bu...

ESA or the European Space Agency has discovered various bodies of liquids under the surface of Mars. They have discovered liquids under the south pole with the help of Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument . The Radar of MARSIS penetrates the surface of Mars and ice, thus sensed liquids in size of oceans and seas. A large body of the liquid was found separated from small bodies by dry patches. Liquid Bodies are found under the south pole of Mars     This is not our first discovery.  MARSIS has found liquids before in 2018. But scientists were sceptical. It once again proved the discovery.   The discovery is a major step of the journey of life on Mars. Whether they are extinct or not, we have a chance for colonisation in Mars. Maybe the liquid is water !

In today's blog, we will be discussing the different types of architecture(current) of the NVidia GPUs. You might have noticed some terms like Pascal, Turing and Ampere . These are the three types of architecture in which NVidia Graphics Card works. Pascal Architecture: Pascal is a codename for the GPU architecture developed by NVidia. This architecture was introduced in 2016.  This architecture is primarily used in the GeForce 10 Series  starting with the GeForce GTX 1080 and GTX 1070, which were released on May 17, 2016, and June 10, 2016, respectively.  The architecture was named after the French mathematician Blaise Pascal. This architecture has 64-128 CUDA cores, a memory bandwidth of 720GiB/s, and NVlink. They also announced the RayTracing support for Pascal Architecture in 2019 after a driver update, Turing Architecture: Turing is a codename for the GPU architecture developed by NVidia. This architecture was introduced in 2018. This architecture was primarily used ...

  A scientific study published in 2019, says that we can find extraterrestrial life by finding the amount of  phosphine  in the atmosphere of planets. Phosphine is a gas produced by anaerobic organisms, organisms who don't need oxygen to live. Phosphine : PH 3 Phosphine is found in gas giants like Jupiter and Saturn. It is because of an abundant source of hydrogen, not due to life forms. But in oxygen-rich like Earth, they are not prevalent.    Phosphine Molecules on the clouds of Venus   Recently, we have discovered phosphine in the clouds of Venus. It is not our first sighting. Vega probes of Soviet union have landed on the surface of Venus and predicted phosphorus. But it was not precise. Vega founded particles about 1 micron thick (Thickness of bacteria) suspending on the atmosphere. But how anything can live in Venus which is covered by a deadly acid, Sulphuric acid! Picture of Surface of Venus One of the ideas is that sulphur molecule (S8) covers mic...

Chandrayaan 1 orbiter has shown that the moon is rusting! People who have studied school would have known that iron rusts when exposed to oxygen or water, and there is no atmosphere surrounding the moon. So how does the moon rust? WHAT IS RUST? Rust or Iron Oxide is a chemical phenomenon found in iron gates, nails and any other iron exposed to oxygen. WHY IS MARS REDDISH? You guessed it! The culprit is rust.       HOW IS MOON GETTING RUST? DOES IT HAVE A SECRET ATMOSPHERE? Moon does not have an atmosphere. It's Earth's fault! Maybe the atmosphere of Earth causes the moon to rust. A type of rust called  Hematite  is found rich in the poles. It first shocked the people. But then they figured out that water on the moon may react with rocks, to cause a variety of rocks! SO, WHAT'S NEXT? Moon will slowly go reddish like mars. That's all.

There are 3 editions in Windows 10. Each edition can be useful in various ways. You can pick the preferred Windows10 from the official website of Windows. If you have been using windows for quite a long time, you might have heard about the different versions of Windows. In this blog, we will be taking a better look at the different editions of Windows 10.  Windows 10 Home Most pre-built computers and laptops are shipped with Windows 10 Home. It contains every feature a common man needs. there are no missing features here when compared to Windows 10 Pro unless you are some sort of a Tech Savy. It does have certain limitations though. This Operating System can only support up to 128GB. You may think why having this much amount of RAM isn't enough. It's because you aren't a Tech Savy. No one usually uses at least more than 64GB RAM either. Another missing "feature" is the BitLocker which allows you to lock your hard drive to encrypt your files. Windows 10 Pro Window...

  Firefox is a fast and famous browser, developed by a non-profit. Firefox's speed and privacy were the key points that brought them up. By hearing all this, at last, you go to Mozilla Firefox Website to download it. But there are different types! Which one should you choose and which one you should download? STABLE EDITION It is the most used and stable Firefox Browser. It is the one you have seen in your computer lab. Firefox updates it every six weeks, checks and revises and, thus bug-free. BETA EDITION   It is one step ahead from the stable version. Beta versions have the next update or release of the stable version but sooner. Beta also has some minor security things for good. For instance, a developer can run an unpublished add-on in the beta version, but not in the stable version since the stable version does only allow authorised add-on. Beta can be good for those who are curious browser to see the next updates. For the developers, we have the next one! DEV EDITI...
