Book Description
Summary: A generalized drag curve that provides an estimate for the drag rise due to compressibility has been obtained for an analysis of wind-tunnel data of several airfoils, fuselages, nacelles, and windshields at speeds up to and above the wing critical speed. The airfoils analyzed had little or no sweepback and effective aspect ratios above 6.5. A chart based on the generalized drag curve is presented from which the terminal velocity of a conventional airplane that employs a wing of moderate aspect ratio and very little sweepback in a vertical dive may be rapidly estimated. In order to use the chart, the only data that need be known about the airplane are a low-speed drag coefficient, the wing critical speed, and the wing loading. The terminal velocities for three airplanes were computed in order to illustrate the use of the method and chart. Good agreement between the estimated terminal velocity and the measured flight terminal velocity was indicated for all three airplanes.

Book Description
Life is going along great. You have settled down, found your life partner, got married, started a family and brought the home of your dreams, the one you will grow old in! That is until your doctor tells you that you have 6 months to live. Due to a terminal cancer diagnosis. A young fit healthy 35-year-old suddenly facing a death sentence and leaving behind a legacy of debt to his young family. I am Michael Romeo, and this is my story. In June 2019 my wife and I returned to the surgeons office for the 6 week checkup following a recent surgery to cut out a Cancerous tumor which was discovered in my esophagus, only to be told 'Michael you will die from Esophageal cancer and it will not be long'. Through this cancer diagnosis / prognosis I have come to learn that I am not the only one who has pushed aside my health, my levels of insurance cover and my finances, because of this I have decided to share my learnings. Since the diagnosis I have the opportunity to make necessary changes in my life to better assist myself and my family. One very exciting change I was able to make was implementing a banking strategy know as the terminal velocity banking strategy. Through this I have been able to get my family in a better financial position and now it truly has become a race against time to become financially free. No joke, I have personally implemented this and am now sharing my personal situation and the results are astounding. Don't be afraid of change and take the first steps in owning your situation.

Book Description
"Body Physics was designed to meet the objectives of a one-term high school or freshman level course in physical science, typically designed to provide non-science majors and undeclared students with exposure to the most basic principles in physics while fulfilling a science-with-lab core requirement. The content level is aimed at students taking their first college science course, whether or not they are planning to major in science. However, with minor supplementation by other resources, such as OpenStax College Physics, this textbook could easily be used as the primary resource in 200-level introductory courses. Chapters that may be more appropriate for physics courses than for general science courses are noted with an asterisk symbol (*). Of course this textbook could be used to supplement other primary resources in any physics course covering mechanics and thermodynamics"--Textbook Web page.
