NITROGEN IS MORE IMPORTANT THAN YOU THINK INTRODUCTION: In this article, we discuss nitrogen its important properties, and some incidents that happened in the past with people and instruments that deal with nitrogen. So, let's start: LIQUID NITROGEN INCIDENT THAT KILLED THREE TECHNICIAN OF NASA: The First space shuttle mission was named STS-1, the first orbital mission of NASA. This mission is uniquely described in this article due to the incident in which three technicians died due to inhalation of excess nitrogen of nitrogen. IMPORTANCE OF NITROGEN: Nitrogen is a crucial element in the periodic table due to many important properties. Nitrogen is a non-toxic & colorless gas that occupies 78% of the atmosphere. HISTORY OF NITROGEN: In the past, scientists had different opinions about this gas. For example, some scientists think it was brunt air because no combination occur in the presence of this element. Some believe it is very toxic and has no life because the environment fil...
Fluid Mechanics: Basic Concept Fluid mechanics is fundamental in the technology around us. Everything we build from cars to airplanes and ships to submarines all move through the fluid. To make them better we need to study the motion of fluid caused by them. The study of different states of matter increases our technological advancement further for example solid-state physics increases our knowledge by which we build and invent new materials which are lightweight, strong, and have great strength. Similarly, studying fluid mechanics increases our technological advancement further. The name of scientists who made useful contributions are Daniel Bernoulli, Leonhard Euler, George Gabriel Stokes, Osborne Reynolds, Ludwig Prandtl, Theodore von Karman, Andrey Kolmogorov, Chia-shun-yih, and John von Neumann. Here is the definition of fluid mechanics: " Fluid mechanics is the branch of physics which deals with the studies of the behavior of fluid (gases or liquid) and their interaction wi...
