Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.
Its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human–computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
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.
"Want To" is a song co-written and recorded by American country music duo Sugarland. It was released in August 2006 as the first single from the album Enjoy the Ride. It was their first single not to feature former member Kristen Hall, although Jennifer Nettles had previously been featured on Bon Jovi's Number One country hit, "Who Says You Can't Go Home", the song was also the first regular Number One hit of Sugarland's career in the U.S., spending two weeks at the top of the Billboard Hot Country Songs charts in late 2006. The duo's members, Jennifer Nettles and Kristian Bush, wrote the song along with Bobby Pinson. The song has sold 856,000 copies in the US as of April 2013.
PBS Digital Studios is a YouTube channel and network through which PBS distributes original educational web video content. It comprises both original series and partnerships with existing YouTube channels. Most of the series are about science, pop culture, art, food, news, and music, though the channel originally launched with a series of video remixes based on PBS icons such as Mr. Rogers.
PBS Digital Studios founded by Jason Seiken in June 2012. They had their first viral hit with a "remix" of autotuned vocals from Mr. Rogers' Neighborhood titled "Garden of Your Mind."
The PBS Digital Studios network has received more than 500 million views and has over 7 million subscribers. Popular series found on their channels include Crash Course, Blank on Blank, It’s Okay To Be Smart, and the multiple Webby Award-winning PBS Idea Channel. Each month, the shows average more than 5 million streams.
Its first scripted series, Frankenstein, MD, launched on August 19, 2014 and ran until October 31, 2014.
"Carrie Anne" is a song written by Allan Clarke, Graham Nash, and Tony Hicks and released by British pop rock group The Hollies. The song was recorded on 1 May 1967 and was released as a single in the same month by Parlophone Records in the United Kingdom and Epic Records in the United States. It became a hit in 1967, reaching #3 on the UK Singles Chart. It was also a hit in the US and Canada, peaking at #9 on both pop charts. It also reached No.4 in the Irish charts.
Actress Carrie-Anne Moss was named (by her mother) in honor of the song, which was released three months before her birth.
According to Allan Clarke the song was written during a concert the group did with Tom Jones and the song was written mainly by Graham Nash and Tony Hicks with Allan Clarke supplying the lyrics for the middle eight. In 1995, Graham Nash revealed that he had written the song for Marianne Faithfull but was "too shy" to use her real name. The song was recorded in only two takes on 1 May 1967 at EMI's Abbey Road Studios. The first take was a false start and can be heard on the compilation The Hollies at Abbey Road: 1966 to 1970.

Today, we’re going to talk about how HUGE programs with millions of lines of code like Microsoft Office are built. Programs like these are way too complicated for a single person, but instead require teams of programmers using the tools and best practices that form the discipline of Software Engineering. We'll talk about how large programs are typically broken up into into function units that are nested into objects known as Object Oriented Programming, as well as how programmers write and debug their code efficiently, document and share their code with others, and also how code repositories are used to allow programmers to make changes while mitigating risk. Ps. Have you had the chance to play the Grace Hopper game we made in episode 12. Check it out here! http://thoughtcafe.ca/hopper/ ...

Today we’re going to take a step back from programming and discuss the person who formulated many of the theoretical concepts that underlie modern computation - the father of computer science himself: Alan Turing. Now normally we try to avoid “Great Man" history in Crash Course because truthfully all milestones in humanity are much more complex than just an individual or through a single lens - but for Turing we are going to make an exception. From his theoretical Turing Machine and work on the Bombe to break Nazi Enigma codes during World War II, to his contributions in the field of Artificial Intelligence (before it was even called that), Alan Turing helped inspire the first generation of computer scientists - despite a life tragically cut short. Ps. Have you had the chance to play th...

Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.

You should ask a lot of people for advice. In my opinion, most people in the world should get their bachelors in CS before working in the field. There's some people that can figure it out on their own, but likely most people need the school structure to learn it
Today we’re going to talk about on how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And it is this ability to store and access information in a structured and meaningful way that is crucial to programming.

Today, Carrie Anne is going to start our overview of the fundamental building blocks of programming languages. We’ll start by creating small programs for our very own video game to show how statements and functions work. We aren’t going to code in a specific language, but we’ll show you how conditional statements like IF and ELSE statements, WHILE loops, and FOR loops control the flow of programs in nearly all languages, and then we’ll finish by packaging up these instructions into functions that can be called by our game to perform more and more complex actions.
