Angular is a complete rewrite from the same team that built AngularJS. The Angular ecosystem consists of a diverse group of over 1.7 million developers, library authors, and content creators. [5] According to the Stack Overflow Developer Survey, Angular is one of the most commonly used web frameworks. [6]
As a result, a PHP 5.3 release was created in 2009, with many non-Unicode features back-ported from PHP 6, notably namespaces. In March 2010, the project in its current form was officially abandoned, and a PHP 5.4 release was prepared to contain most remaining non-Unicode features from PHP 6, such as traits and closure re-binding.

A three-phase induction motor has a simple design, inherently high starting torque and high efficiency. Such motors are applied in industry for many applications. A three-phase motor is more compact and less costly than a single-phase motor of the same voltage class and rating, and single-phase AC motors above 10 hp (7.5 kW) are uncommon. Three ...

Light and Matter – an open-source textbook, containing a treatment of optics in ch. 28–32; Optics2001 – Optics library and community; Fundamental Optics – Melles Griot Technical Guide; Physics of Light and Optics – Brigham Young University Undergraduate Book; Optics for PV – a step-by-step introduction to ...
Because of their ultraflat surfaces, when wrung, gauge blocks adhere to each other tightly. Properly wrung blocks may withstand a 300 N (67 lbf) pull. [5] The mechanism is a combination of: [4] [5] [needs update] Vacuum applies pressure between the blocks because the air is squeezed out of the joint [note 1]
Mescaline, also known as mescalin or mezcalin, [8] and in chemical terms 3,4,5-trimethoxyphenethylamine, is a naturally occurring psychedelic protoalkaloid of the substituted phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin.
Machining is a form of subtractive manufacturing, [1] which utilizes machine tools, in contrast to additive manufacturing (e.g. 3D printing), which uses controlled addition of material. Machining is a major process of the manufacture of many metal products, but it can also be used on other materials such as wood , plastic , ceramic , and ...
In physics, angular acceleration (symbol α, alpha) is the time rate of change of angular velocity.Following the two types of angular velocity, spin angular velocity and orbital angular velocity, the respective types of angular acceleration are: spin angular acceleration, involving a rigid body about an axis of rotation intersecting the body's centroid; and orbital angular acceleration ...
