And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made. Its wild success tells us that the mathematical description provided by quantum mechanics reflects deep truths about reality. And by far the most successful, most predictive formulation of quantum mechanics is quantum field theory. It is our best description we have of the fundamental workings of reality. And the first part of quantum field theory that was derived – quantum electrodynamics – is the most precise, most accurate of all.

Over the past quarter century, the greatest geniuses of the modern era discovered the two keys to the fundamental nature of reality. Einstein’s theories of special and general relativity had changed forever the way we think of motion, space, and time. And the emerging field of quantum mechanics had radically altered our understanding of the fundamental building blocks of the universe. Yet this year one brilliant insight would bring these theories together and unveil the quantum fabric of reality. It would also predict the existence of antimatter.

During the last week the FAA have published and Emergency Airworthiness directive regarding the Boeing 737MAX and how to handle it in case of a failure of its Angle Of Attack sensor (Alpha Vane). Boeing has also issued Bulletins to all 737MAX and 737NG operators regarding the “Manoeuvring Characteristics Management System (MCAS). In This video I will be trying to explain how all of these systems fit together and Why this is such an important thing for pilots to know and understand. I want to EMPHASISE that these are just descriptions of these systems and we still do not know exactly what happened on that flight. To get awesome, fact-full information regarding inflight incidents and accidents, check out: https://www.avherald.com If you have further questions on these systems or about any other Aviation related topic, feel free to contact me in the Mentour Aviation app!

After making 18 orbits of Earth since its launch early Saturday morning, the Crew Dragon spacecraft successfully attached to the International Space Station’s Harmony module forward port via “soft capture” at 5:51 a.m. EST while the station was traveling more than 250 miles over the Pacific Ocean, just north of New Zealand. As the spacecraft approached the space station, it demonstrated its automated control and maneuvering capabilities by arriving in place at about 492 feet (150 meters) away from the orbital laboratory then reversing course and backing away from the station to 590 feet (180 meters) before the final docking sequence from about 65 feet (20 meters) away. The Crew Dragon used the station’s new international docking adapter for the first time since astronauts installed it during a spacewalk in August 2016, following its delivery to the station in the trunk of a SpaceX Dragon spacecraft on its ninth commercial resupply services mission. For the Demo-1 mission, Crew Dragon is delivering more than 400 pounds of crew supplies and equipment to the space station. A lifelike test device named Ripley also is aboard the spacecraft, outfitted with sensors to provide data about potential effects on humans traveling in Crew Dragon.

SpaceX Starship Raptor Engine breaks Russian rocketry record held for two decades SpaceX CEO Elon Musk says the company’s Raptor engine, meant to power Starship and Super Heavy, has surpassed a rocketry record held by Russian scientists and engineers for more than two decades. Known as combustion chamber pressure, Raptor has reportedly surpassed a modern Russian engine known as the RD-180, reaching forces equivalent to one Tesla Model 3 balanced on every square inch of Raptor’s combustion chamber, the hardware directly adjacent to a rocket engine’s bell-shaped nozzle. Keeping that in mind, in this video, Engineering Today will discuss about combustion chamber pressure of SpaceX Raptor engine as well as Russian, R D-1 80. Why Elon Musk think, Raptor can truly outperform the R D-1 80 in near future? Let’s get into details.
