Heart

The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes. The heart is located in the middle compartment of the mediastinum in the chest.

In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish in contrast have two chambers, an atrium and a ventricle, while reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.

The Heart

The Heart was a music channel on XM Satellite Radio that specialized in playing soft AC love songs. It was available on channel 23 on XM and channel 819 on DirecTV. The program director of The Heart was Mike Abrams. The channel was dropped as part of the Sirius/XM merger on November 12, 2008. It was replaced by Sirius's similar The Bridge and Sirius XM Love (formerly Sirius Love).

Artists that were on the playlist include Whitney Houston, Elton John, James Taylor and Phil Collins.

The Heart was on XM's channel lineup at service launch. In 2004 and 2005, the channel's regular format was temporarily replaced with a pop Christmas music format called "Holly" between Thanksgiving and Christmas; in 2006, Holly preempted XM's U-Pop channel instead and The Heart retained its normal format through December.

Kendrick Lamar

Kendrick Lamar Duckworth (born June 17, 1987) is an American rapper from Compton, California. Lamar embarked on his musical career as a teenager under the moniker K-Dot, released a mixtape which garnered local attention and led to his signing with Carson-based independent record label Top Dawg Entertainment (TDE). Lamar began to gain major recognition in 2010 after his first retail release, Overly Dedicated. The following year, he released Section.80, his first independent album, exclusively through iTunes. The album included Lamar's debut single, "HiiiPoWeR". By that time, Lamar had amassed a large internet following and had already worked with several prominent artists in the hip hop industry, including The Game, Snoop Dogg, and Busta Rhymes.

Lamar secured a recording contract with Aftermath and Interscope Records in 2012. His major-label debut album, good kid, m.A.A.d city, was released in October 2012 to universal acclaim. The record contained the top 40 singles "Swimming Pools (Drank)", "Bitch, Don't Kill My Vibe", and "Poetic Justice". Upon its release, the album debuted at number two on the U.S. Billboard 200 chart and was later certified platinum by the Recording Industry Association of America (RIAA). In early 2013, MTV named Lamar the No. 1 "Hottest MC in the Game" on their annual list.

Khan Academy

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.

History

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.

Crash Course

Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.

Plot

Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.

The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
