Let's talk about what afterburners are, when they're used, and how they work. In my first 'In a Nutshell' video, I'm testing the waters on giving simplified explanations for complicated topics. Let me know what you think.

![Explained: Angle of Attack [Airplanes]
The angle of attack (AoA) is one of the most important parameters when studying how planes fly. By definition, it is the angle between some reference line of the plane (in our case the chord line of the wing) and the relative wind. The AoA will be vital when talking about lift curves and how wings generate lift.

![Explained: Edit Text Box GUI [MATLAB]
Edit text boxes can be used to input numbers or strings in your GUI. This video explains how create an edit text box and retrieve both string data and double data from it. Explained: Edit Text Box GUI [MATLAB]](https://i.ytimg.com/vi/GfsClzG-fls/mqdefault.jpg)
![How To: Find Mach Number from a Picture (Part 2)
Want to look at a picture of a bullet/plane/etc. and be able to approximate the Mach number? In the previous video on this topic (linked to below), I showed three different methods of approximating the Mach number from angles measured in a Schlieren image.

When using the Taylor-Maccoll code, I used the shock wave angle and the Mach number guess as inputs to return a cone angle. The cone angle was then compared to the cone angle measured in GIMP using the Measure Tool. In this video, Ive updated the code so that it plots a contour plot of the Mach number (cone plotted in black). I am able to overlay that image onto the actual Schlieren image, adjust the opacity of the overlay, and compare the solution from Taylor-Maccoll theory to the actual shock seen in testing.

![Explained: Assumptions for Axisymmetric Conical Flow [Taylor-Maccoll]
Its extremely important to understand the assumptions used to derive an equation. This video goes over the assumptions we will be using for the Taylor-Maccoll conical flow problem, and the impact each assumption will have later on in the derivation.
