To consider the boundaries from a holistic perspective, all operation limits have to be derived using the same turbulence model. This results in an operation phase space in relation to the separatrix electron density and temperature. Here, we discuss the underlying physics, the historical ...

A unit vector in physics is an object that has a magnitude of 1. They are used to represent a direction. How do you write unit vectors? Any vector has a corresponding unit vector. The unit vector can be written as the vector divided by its magnitude. How do you find the unit vector...
1. How do cross-platform mobile apps differ from native apps in terms of performance and user experience? Cross-platform mobile apps may have slightly lower performance than native apps, as they rely on a single codebase that has to work on multiple platforms. However, advances in cross-platf...
To understand wingsuit aerodynamics and how the outfit allows its wearer to really fly, you have to understand the basic physics of flight. The first principle to keep in mind is that air is a fluid -- much like water. Try to move your hand, palm flat, through a tub of water or stic...
Viewed most basically, the existence of curiosity is counterintuitive to evolutionary theory: The most curious among us should've been killed off before getting the chance to reproduce, with the trait losing out to natural selection. We don't really need to do crossword puzzles or find out ...
And what do they hope to gain by solving the puzzle? Is dark matter the secret to solidifying the standard model of particle physics, or will it fundamentally alter how we view and understand the world around us? Evidence for Dark Matter: The Beginning Astronomers have been fascinated by ...

They can make the weapon smaller in diameter. The smaller cross-sectional area means that the bomb has to move less material (earth or concrete) "out of the way" as it penetrates. They can make the bomb faster to increase its kinetic energy. The only practical way to do this is to ad...
