Dated:-31 Aug 2021 Solar storms or coronal mass ejections are known to cause damage to electrical grids and cause blackouts, however, experts are of the belief that they could also adversely affect the internet infrastructure, causing a global internet outage.  This was revealed by the University of California, Irvine’s Sangeetha Abdu Jyothi at the SIGCOMM 2021 data communication conference last week. She revealed, in her research, that even though local and regional internet infrastructure would be at low risk of damage during extreme solar storms as they mostly use fibre optic cables and are not affected by geomagnetically induced currents. Even short cable spans that are susceptible to these storms are grounded regularly, eliminating the possibility of damage.  However, the same cannot be said for undersea cables that connect continents together. Even though most of these continents are connected via fibre optic cables, the repeaters that amplify the current at regular inte...

OPTIMUS IS FUTURE😍 Tesla will build a humanoid robot called Tesla Bot, CEO Elon Musk said on Thursday. “We’re also good at sensors and batteries and we’ll probably have a prototype next year that looks like this,” Musk said, shortly after an actor in a body suit designed to look like the Tesla robot gyrated wildly on stage. He remarked that the actor was not a real robot, but “the Tesla Bot will be real.” The announcement was made as part of AI Day, a series of tech talks hosted by Tesla in California to recruit machine learning talent.  The Tesla Bot is an example of Musk’s showmanship, in which he announces that Tesla is working on exciting products scheduled for years into the future to energize backers including employees, customers, and investors. Often, those announcements don’t happen on the timeline predicted. For instance, at an ‘Autonomy Day” event in Apr. 2019, Musk said the company would have 1 million autonomous “robotaxis” on the road in 2020. Those robotaxis are now...

 Planets, stars and galaxies NAJAM UL GUL At the beginning of your trip through space, you might recognize some of the sights. The Earth is part of a group of planets that all orbit the Sun – with some orbiting asteroids and comets mixed in, too. You might know that the Sun is actually just an average star, and looks bigger and brighter than the other stars only because it is closer. To get to the next nearest star, you would have to travel through trillions of miles of space. If you could ride on the fastest space probe NASA has ever made, it would still take you thousands of years to get there. If stars are like houses, then galaxies are like cities full of houses. Scientists estimate there are 100 billion stars in Earth’s galaxy. If you could zoom out, way beyond Earth’s galaxy, those 100 billion stars would blend together – the way lights of city buildings do when viewed from an airplane. Recently astronomers have learned that many or even most stars have their own orbiting pla...

What are the benefits of living on Mars? Why did Columbus travel west? Why did Marco Polo head east? Because it is that pull, that unknown, that prospect of adventure that compels humans to seek new frontiers to explore.   There are a number of reasons to travel to Mars.   The first is the realization of an amazing dream! Sending a manned mission to Mars is a fantastic adventure. Imagine living on another planet, millions of miles from the Earth; looking up into the sky with the knowledge that one of the 'stars' is actually the planet you were born on. Who can even envision the incredible feeling of being the first human in history to step out of the capsule and leave your footprint on the surface of Mars? By this we implore you to not just think of that feeling for the astronaut, but the experience for all those watching back home. Those who observed Neil Armstrong land on the Moon all those years ago still remember every detail – where they were, who they were with and how t...

  When the astronauts land on Mars, there will be storable food from Earth waiting for them to use. The storable food from Earth will only serve as emergency rations, which means the astronauts will try to eat as much fresh food that they produce on Mars as possible. It is likely that algae and insects will also be part of the diet on Mars. Food production will occur indoor under artificial lighting. In total, there will be approximately 80 m2 available for plant growth in the original habitat. The first crew will also be able to use the habitat of the second crew to grow food because the hardware for the second crew lands only a few weeks after the first crew lands. A thick layer of Martian soil on top of the inflatable habitat will protect the plants (and the astronauts) from radiation. CO2 for the plants is available from the Mars atmosphere and water is available through recycling and the soil on Mars. Nutrients for the plants could come from recycling human waste or could b...

  The Indian archipelago of Andaman and Nicobar is home to a new species of plant. Biologists found a marine green algae during a trip to the island in 2019. Scientists spent nearly two years identifying this species for the first time, which is a laborious process. A new algae species was found on the islands for the first time in more than four decades, according to researchers. A species of Acetabularia has been named by scientists from the Central University of Punjab. JALAKANAYA is a goddess of the seas and mermaids in Sanskrit. Hans Christian Anderson's eponymous fairy tale, Little Mermaid, influenced the scientist's research. "The newly discovered species is so stunning. It has caps with intricate designs as if it were umbrellas of a mermaid," said Dr Felix Bast, who led the study. The main feature of the newly discovered species is that the plant is made up of one gigantic cell with a nucleus. The scientists spent more than 18 months sequencing the plant DN...

  How does the Mechanical Mouse work? A mechanical mouse consists of a heavy rubber ball whose movement makes the cursor move on the screen. Commonly known as the ‘rolling rubber ball’ mouse, it is considerably heavy, thanks to the rubber ball, a few wheels, and a number of other mechanical parts present inside it. When you move the mouse, the ball rolls beneath it, pushing the two plastic wheels/rollers linked to it in the process. One of those wheels detects side-to-side movement (x-axis wheel) and the other (y-axis wheel) detects movement in the up-and-down direction. Both of these wheels consist of spokes that ‘break’ a thin light beam inside the mouse. The number of times the beam breaks helps to calculate how far the mouse has moved. For instance, when you move the mouse straight up, the y-axis wheel turns. The farther up you go, the more the ball pushes the wheel and the more it breaks the light beam. This helps to determine how far the mouse has moved straight up....

  QUANTUM COMPUTERS👇 A quantum computer used by scientists in Russia has been able to send a single electron back in time, enabling the computer to be reset from a moment earlier Fall Back In an experiment conducted on a quantum computer, Russian scientists appear to have reversed the flow of time. There is little chance that the findings would lead to a human-powered time machine. IBM's public quantum computer was restored to its previous state by researchers published Wednesday in the journal Nature Scientific Reports — a nuanced result, but one that could have striking implications for computing, quantum physics, as well as our understanding of time. “We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time,” Gordey Lesovik, a quantum physicist from the Moscow Institute of Physics and Technology who led the research project, said in a university-published press release. Great Scott A team led by Lesovik ran tho...

  LOCKHEED SR-71 BLACKBIRD Twin-engine, two-seat, supersonic strategic reconnaissance aircraft; airframe constructed largley of titanium and its alloys; vertical tail fins are constructed of a composite (laminated plastic-type material) to reduce radar cross-section; Pratt and Whitney J58 (JT11D-20B) turbojet engines feature large inlet shock cones. No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world's fastest jet-propelled aircraft. The Blackbird's performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War. This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its last flight, March 6, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilo...

  What is Disc Brake? Why disc brakes have holes in it? Let's gain some knowledge👀 It is pretty much obvious that brakes are used to stop the vehicle in motion. Hence you could imagine the amount of friction that acts between the brake pads and the walls of the discs.  Due to the first law of thermodynamics, the work done to stop the car produces heat (As a result of friction). There are different kinds of disc brakes. Some are drilled (Like your bike’s wheel). Some are slotted, some are patterned, and some are ventilated(Like your car). Now if you would look closer, you can see a slit along the circumference of the disc in the car. WHY IS VENTILATED BETTER THAN DRILLED? This is because, your bike might be producing only less than half of the heat produced by the discs in the car. More over, a car will have greater inertia of mass than a bike because of obvious reasons. Hence the discs must be able to take the load and provide better disc cooling.  Vented discs give b...

  Approximately four people have applied to live in Mars Dune Alpha for a year in preparation for sending astronauts to Mars. Using a 3D printer, this complex in Houston's Johnson Space Center was made to resemble a Martian habitat. Volunteers will be trained for a simulated Mars exploration mission that may include spacewalks, communications breakdowns, and limited food and resources. This will be the first of three experiments planned by NASA for fall of next year. At this time, there are no windows and all food will be ready-to-eat space food. NASA opened the application process on Friday, but it isn't looking for just any applicant. Pilots must have at least one year of command experience in the air and to have a master's degree in a science, engineering, or math field. The competition is open only to Americans and permanent U.S. residents. The applicant must be between the ages of 30 and 55, a physically fit and healthy individual, without dietary restrictions or motio...

  WHAT  IS A STARSHIP? A starship is a spacecraft designed for travelling between planetary systems. A starship is being developed by the company namely SpaceX under the leadership of Elon Musk(C.E.O and founder of SpaceX).It is a spacecraft and rocket combination that could carry more than 100 people on The red planet called MARS. AN OVERVIEW: At launch, the spacecraft, called Starship, will sit atop a rocket called Super Heavy. The combined system will stand 120m (394ft) -tall and is also referred to as Starship.  With its nosecone and landing fins, the stainless-steel vehicle resembles the rocket ships from the golden age of science fiction. At the rear of the 50m (160ft) -long craft are six highly efficient Raptor engines, developed over the course of a decade by SpaceX. The combustion takes place in stages, and the engine's design cuts the amount of propellant that's wasted. Towards the middle of the vehicle is the propellant tanks. These feed liquid methane (CH4)...

  What is Airship? An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only used for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation, typically housed in one or more gondolas suspended below the envelope . Airships were the first aircraft capable of cont...

  What is firmware? Firmware is a small piece of software that makes hardware work as its manufacturer intended it to. It consists of programs written by software developers to make hardware devices "tick." Without firmware, most of the electronic devices we use daily wouldn't be able to work.  They would not do anything. For example, did you know that a simple traffic light has firmware on it? Yes, it does, and the firmware is what tells it to change the lights at regular intervals.  Without firmware, the traffic light would be just a "stupid" mast, placed on the side of the road, doing nothing except looking bored. What is firmware in the case of less sophisticated hardware devices such as traffic lights, washing machines, card machines, surveillance cameras, and TVs? The firmware is all the software on them, also acting as their operating system and controlling everything about those devices’ functioning. Traffic lights need firmware to run. We often tend...

  How do Planes fly? If you've ever watched a jet plane taking off or coming in to land, the first thing you'll have noticed is the noise of the engines. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditional propellor engines. You might think engines are the key to making a plane fly, but you'd be wrong. Things can fly quite happily without engines, as gliders (planes with no engines), paper planes, and indeed gliding birds readily show us. If you're trying to understand how planes fly, you need to be clear about the difference between the engines and the wings and the different jobs they do. A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. So it's the engines that move a ...

  How does Intelligent Transport System works? 😃 LETS KNOW HOW! Traffic Management Centre (TMC) is the vital unit of ITS. It is mainly a technical system administered by the transportation authority. Here all data is collected and analyzed for further operations and control management of the traffic in real time or information about local transportation vehicle. Well-organized and proficient operations of Traffic Management Centre depends on automatized data collection with precise location information than analysis of that data to generate accurate information and then transmitting it back to travelers.  Let’s understand the entire process in a more detailed way. Strategic planning needs precise, extensive and prompt data collection with real-time observation. So the data here is collected via varied hardware devices that lay the base of further ITS functions. Rapid and real-time information communication is the Key to proficiency in ITS implementation so this aspect of I...
