Plane Crash
Plane Crash: “Flying is not inherently dangerous, but to an even greater extent than the sea, it is terribly unforgiving ….” —Captain A. G. Lumplugh, British Aviation Insurance Group ________ Section-1 Prologue: Flight is, and always will be a marvel of human achievement. The opportunity to “spread your wings” and fly is an unbelievable privilege and experience. Airways have undergone a drastic evolution in the past decade, with airplanes becoming the most widely used means of transport across the globe. This is primarily because of the higher reliability, least travel time and a better cost effectiveness of the airways over other modes of transport. In addition to that, airports are traditionally considered as the country’s signature monuments. It showcases to an outsider, the first and the last impression of the country. Commercial aviation transports more than four billion passengers annually on airliners. Aviation is a critical part of national economy, […]
THE ATOM
___________ THE ATOM: ___________ The figure above is an animation of the nuclear force (or residual strong force) interaction between a proton and a neutron. The small colored double circles are gluons, which can be seen binding the proton and neutron together. These gluons also hold the quark-antiquark combination called the pion (meson) together, and thus help transmit a residual part of the strong force even between colorless hadrons. Quarks each carry a single color charge, while gluons carry both a color and an anticolor charge. The combinations of three quarks e.g. proton/neutron (or three antiquarks e.g. antiproton/antineutron) or of quark-antiquark pairs (mesons) are the only combinations that the strong force seems to allow. ________ Prologue: Since childhood I was curious about breaking down any matter (table/chair) into smaller pieces continually till I reach a point where it cannot be broken down. What is that point? Is matter infinitely divisible? […]
