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 flows slower when we are ne

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. They have partnered with Microsoft closely for Direct X 12 to build a new API which will efficiently render gaming assets Scott Herkelman, VP of AMD, introduced AMD Radeon RX 6800 XT. This processor will have 72 compute units with up to 2.01 GHz of Game Clock and 2.25 GHz of Boost Clock. It also comes with 128MB of Infinity Cache and 16GB of GDDR6 VRAM. This GPU consumes onl

  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 DEBRIS Nasa is constru

"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 but diffusion. T

AMD Ryzen The AMD Ryzen 5000 Series with Zen 3 architecture has been unveiled yesterday during a live launch event. In this blog, we will be looking at the highlights of the launch event. The launch event started off with a great montage of their first launch of AMD processors, their first launch of the Ryzen series, and the first launch of their Threadripper series. The CEO of AMD, Dr. Lisa Su explained the need for computing power in the quarantine days of 2020. The AMD chips will now also power the new Sony PlayStation 5 and the Microsoft Xbox Series X and series S. This time AMD is giving more importance towards Gamers and Gaming. Game begins with AMD - Dr. Lisa Su, CEO of AMD AMD Ryzen is also the first to bring the 7nm processors in the market. It is also the best in terms of power efficiency and highest in multi-threaded performance. Zen 3 increases their lead in overall perform
