Free object

In mathematics, the idea of a free object is one of the basic concepts of abstract algebra. Informally, a free object over a set A can be thought of as being a "generic" algebraic structure over A: the only equations that hold between elements of the free object are those that follow from the defining axioms of the algebraic structure. Examples include free groups, tensor algebras, or free lattices. The concept is a part of universal algebra, in the sense that it relates to all types of algebraic structure (with finitary operations). It also has a formulation in terms of category theory, although this is in yet more abstract terms. (Wikipedia).

Newton's 2nd Law (14 of 21) Free Body Diagrams; An Explanation

Describes what free body diagrams are. How to determine if an object is experiencing balanced or unbalanced forces and what it is doing. Free-body diagrams show the relative magnitude and direction of all forces acting upon an object. A free body diagram is a vector diagram. The relative s

Scott Aaronson - Physics of Free Will

Free will has traditionally been a problem in philosophy. Recently, the battleground of free will has shifted to neuroscience. Now some claim that to solve the problem of free will, we must go far deeper, to the fundamentals of physics, down to subatomic forces and particles. But don't fre

Daniel Dennett - What is Free Will?

Free will is a problem. If it seems obvious that you are perfectly free to choose and decide, then it seems perfectly clear that you do not understand the problem. Free will is a huge problem, because our sense of free will and the physical structure of the world contradict each other. Fo

Show Me Some Science! Forces and Falling

Show Me Some Science! is a new series of podcasts from the Little Shop of Physics. In this episode, we look at different objects in free fall. When you drop an object from a high height, and it is in the air, there are no forces acting on it other than gravity. This is called free fall. Ca

RubyConf 2021 - Optimizing Ruby's Memory Layout by Peter Zhu & Matt Valentine-House

Ruby’s current memory model assumes all objects live in fixed size slots. This means that object data is often stored outside of the Ruby heap, which has implications: an object's data can be scattered across many locations, increasing complexity and causing poor locality resulting in redu

Introduction to Free Body Diagrams or Force Diagrams

We define and discuss how to draw Free Body Diagrams which are also called Force Diagrams. In addition we define the force normal and the force applied. Force of friction and center of mass are briefly discussed, however, a much more detailed discussion of each is left for later lessons.
