HTML and CSS are markup languages and the building blocks that make up the web. This course is called "Not your Typical Intro" because it does not follow the usual pattern of other courses and tutorials that you find on the Internet. Usually HTML and CSS are taught with a focus on language syntax. But knowing syntax alone does not enable you to create a webpage from a design. You need to know where to start and how to approach the task, in other words - you need to learn how to think like a front-end developer. In this course you will learn how to convert digital design mockups into static web pages. We will teach you how to approach page layout, how to break down a design mockup into page elements, and how to implement that in HTML and CSS. You will also learn about responsive design techniques, which are increasingly important in a world where mobile devices and TV screens are used more and more often to look for information and entertainment.

Inferential statistics allows us to draw conclusions from data that might not be immediately obvious. This course focuses on enhancing your ability to develop hypotheses and use common tests such as t-tests, ANOVA tests, and regression to validate your claims.

This course provides a one-semester overview of information security. It is designed to help students with prior computer and programming knowledge — both undergraduate and graduate — understand this important priority in society today. The technical content of the course gives a broad overview of essential concepts and methods for providing and evaluating security in information processing systems (operating systems and applications, networks, protocols, and so on). In addition to its technical content, the course touches on the importance of management and administration, the place information security holds in overall business risk, social issues such as individual privacy, and the role of public policy.

In this course we will build an iPhone app that records a conversation between you and a friend, and then makes your voices sound like a Chipmunk or Darth Vader. This course will introduce you to iOS app development in Swift, a new programming language from Apple, and serves as your launching point into the [iOS Developer Nanodegree](https://www.udacity.com/course/nd003).

In this introductory course, you'll learn and practice essential computer science concepts using the Java programming language. You'll learn about Object Oriented Programming, a technique that allows you to use code written by other programmers in your own programs. You'll put your new Java programming skills to the test by solving real-world problems faced by software engineers.

This course will teach you the basics of Java Programming, still one of the most popular languages used.

Learn the fundamentals of JavaScript, the most popular programming language in web development.

jQuery is the most popular JavaScript library today, in use by over 60% of the top 100,000 most visited websites. This course will teach you how to use jQuery’s core features - DOM element selections, traversal and manipulation. You'll also learn how to read and make sense of jQuery's documentation, making it easy for you to go beyond the methods taught in this class and take advantage of jQuery's full array of features! This course is also a part of our Front-End Web Developer Nanodegree.

Machine Learning is a first-class ticket to the most exciting careers in data analysis today. As data sources proliferate along with the computing power to process them, going straight to the data is one of the most straightforward ways to quickly gain insights and make predictions. Machine learning brings together computer science and statistics to harness that predictive power. It’s a must-have skill for all aspiring data analysts and data scientists, or anyone else who wants to wrestle all that raw data into refined trends and predictions. This is a class that will teach you the end-to-end process of investigating data through a machine learning lens. It will teach you how to extract and identify useful features that best represent your data, a few of the most important machine learning algorithms, and how to evaluate the performance of your machine learning algorithms. This course is also a part of our Data Analyst Nanodegree.

Study physics abroad in Europe -- virtually! Learn the basics of physics on location in Italy, the Netherlands and the UK, by answering some of the discipline's major questions from over the last 2000 years.

This class teaches you how to build powerful web and mobile apps and host them in the cloud, without writing a line of code. By the end of this short course, you'll use the skills you've developed to conceptualize and create your own app. To get you there, your instructors Samantha and Andy will first help you build an app that could be used to manage logistics at a music festival. Though this is a very specific app use case, the skills you learn will be applicable to just about any business app you’d want to develop.

Build your earth science vocabulary and learn about cycles of matter and types of sedimentary rocks through the Education Portal course Earth Science 101: Earth Science. Our series of video lessons and accompanying self-assessment quizzes can help you boost your scientific knowledge ahead of the Excelsior Earth Science exam . This course was designed by experienced educators and examines both science basics, like experimental design and systems of measurement, and more advanced topics, such as analysis of rock deformation and theories of continental drift.

In this course you’ll get started working on your very first Progressive Web App - a web app that can take advantage of many of the features native applications have enjoyed. You’ll also get more experience in creating a web app that works offline using Service Workers. Finally, you’ll make your app installable to the user’s home screen with the Web App Manifest file.

Introduction to Psychology is a journey through all of the major psychological concepts and principles. The knowledge gained from this course will allow students to critically evaluate psychological research and have a more in-depth understanding of human thought and behavior.

Take Your Business Idea to the Next Level!

This course is a quick, fun introduction to using a relational database from your code, using examples in Python.
