Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Calculus is the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Gottfried Leibniz. Today, calculus has widespread uses in science, engineering and economics and can solve many problems that algebra alone cannot.
Calculus is a part of modern mathematics education. A course in calculus is a gateway to other, more advanced courses in mathematics devoted to the study of functions and limits, broadly called mathematical analysis. Calculus has historically been called "the calculus of infinitesimals", or "infinitesimal calculus". The word "calculus" comes from Latin (calculus) and refers to a small stone used for counting. More generally, calculus (plural calculi) refers to any method or system of calculation guided by the symbolic manipulation of expressions. Some examples of other well-known calculi are propositional calculus, calculus of variations, lambda calculus, and process calculus.

Jeff Herman (Jeffrey Herman; born 1959) is a trial lawyer who specializes in representing victims of sexual abuse. He is most noted for exposing the clergy sexual abuse scandal in the Archdiocese of Miami and the Archdiocese of Denver. Herman is also noted for his landmark $100 million verdict on behalf of a client who was sexually abused by Rev. Neil Doherty, one of the largest verdicts ever against an individual priest.
Said to be driven by his commitment to break the silence on child sexual abuse, Jeff consistently represents alleged victims of abuse. For over a decade, Herman has made national headlines exposing sexual predators and the institutions that protect them. He has been featured in The New York Times, USA Today, Forbes, People, and New York magazine and is a contributor to The O'Reilly Factor, MSNBC, and CNN. Herman has been recognized for his unique child forensic interviewing technique and he trains professionals from various child welfare organizations on how to help sexually abused children heal through disclosure.
Justin Clark (born October 17, 1988, Atlanta, Georgia) is an American soccer player who most recently played for Orlando City in USL Pro, the third tier of the American soccer pyramid.
Clark attended Marist School in Georgia, winning a state championship in 2006. He then attended and played three years of college soccer at Rollins College, playing in 41 games and scoring 3 goals and becoming an All-American his senior year.
Clark played with Orlando City during the 2012 preseason, and played in almost every preseason game for the Lions, scoring one goal. He signed his first professional contract with Orlando City on April 4, 2012. He was released upon the conclusion of the 2014 season, a casualty of the club's transition to Major League Soccer.
Calculus 1 Lecture 1.1: An Introduction to Limits
I want you to feel that you could have invented calculus for yourself, and in this first video of the series, we see how unraveling the nuances of a simple geometry question can lead to integrals, derivatives, and the fundamental theorem of calculus.

What is calculus? In this video, we give you a quick overview of calculus and introduce the limit, derivative and integral. We begin with the question “Who invented Calculus?” Next, we talk about the two main tools you’ll study: derivatives and integrals. To understand both of these you’ll first learn about limits. After you learn how to compute the derivative and integral for basic functions and apply them to real-world problems, you’ll move up to higher dimensions and study things like “partial derivatives” and “multiple integrals.” ******* Subscribe today! http://www.youtube.com/subscription_center?add_user=SocraticaStudios Support us on Patreon at: https://www.patreon.com/socratica ******* Written and Produced by Michael Harrison Michael Harrison received his BS in math from C...
This video will give you a brief introduction to calculus. It does this by explaining that calculus is the mathematics of change. A couple of examples are presented, and then limits, derivatives, and integrals are introduced. For more videos please visit http://www.mysecretmathtutor.com

The foreign concepts of calculus often make it hard to jump right into learning it. If you ever wanted to dive into the world of mathematics - or if you are just having difficulty in your calculus class - and are having a hard time grasping the ideas, you should watch this video to go over the core principles of calculus in a way that requires no background knowledge: at a fifth grade level.

The war is over
The last battles are gone
Swords laying broken
My bloodwork is all done
I sit down for calming
My breath is lessening
I�m starting to tremble
My sight is clearing
My head is weary
A dreadful awakening
What has driven me
Into insanity
Awaking from this dreadful tragedy
I return to myself
Beginning to dwell in this elegy
Put my anger on the shelf
Awaking from this dreadful tragedy
I return to myself
Beginning to dwell in this elegy
Put my anger back on the shelf
I look around
As I raise from my rest
Discover what I�ve done
No life I have left
My heart is in pieces
My soul is laying bare
Awaking from this dreadful tragedy
I return to myself
Beginning to dwell in this elegy
Put my anger on the shelf
Awaking from this dreadful tragedy
I return to myself
Beginning to dwell in this elegy
