In this video, I want to talk to you about how to get a copy of Mathematica, or how to use the Wolfram language online. Now, the first thing that I suggest that you do is go to your organization whether that be your school, your college, university, the institution where you work and find out whether they have a site license. Many institutions have a site license for Mathematica and you can use the product free of charge. If not, let's have a look here at the Wolfram research website, its just wolfram.com, W-L-F-R-A-M, wolfram.com. This is where you can learn all about the Wolfram language and everything that the Wolfram Company offers. What we're interested in at the moment is just the products and services and two things that I want to show you: mathematically and then the programming lab. Let's go to the Mathematica website. Mathematica is a coding environment in which we can use the Wolfram language. If your institution does not have a site license, you can certainly purchase a copy of Mathematica and there are a variety of options available to you. First of all, you can click on Try Now and you can download a copy that you can use for a limited time. Just to get familiar with the desktop version. Let's move on to pricing. You can see pricing for Industry, Government, Education, Students, and Home and Hobby. I would really suggest that you start with the Home and Hobby versions. You can see the most popular version is Mathematica Desktop. You can buy it for $335 or, much cheaper if you just subscribe on a yearly basis for a $170 and that is really going to allow you to get a certain number of upgrades for that year. We see the most popular version here is the $335 option just Mathematica Desktop. You can also just pay a subscription every year at $170 and really if you divide that by 12, it really is not a lot of money every month. Have a look at these other options as well. If we go to the programming lab, that is something that you can use absolutely freely online. You can just start programming right away, you don't even have to sign in, just click on Start Now. What I would suggest though, is that you do create a free account so that you are able to upload some of your data files and that you can store the notebooks that you do create online in the Wolfram Cloud. Now, the free version is going to have some limitations. Most notably on the sides of documents and number of documents that you can store, but it would still be absolutely enough for the purposes of this course and for your work as you start doing your own data analysis. So, I do suggest you go to this website, wolframcloud.com and you can see that I'm already signed in. But if you click here on Programming Lab, it will take you to a page where you can sign up for free. Then, every time you log in, your details will be remembered and you can simply log in. Let's go to the programming lab. This is the Programming Lab. You see that I'm using the absolutely free account here and it'll also allow me to upgrade because you can also pay a monthly subscription, and get more space on the Wolfram Cloud for your documents. You can watch a short video introduction or you can read this elementary introduction to the Wolfram language. A nice and neat short little book introducing you to the Wolfram language. You can start a brand new Notebook and I'm going to teach you all about Notebooks. A Notebook is really the document in which we are going to write our code, get our results, but it is so much richer and you will soon find out more about that. In the Wolfram Cloud, you have a little button at the top, Cloud Files. This is where you can create new folders, new notebooks, and that is just a normal folder structure as you would in any other cloud product or on your hard drive. You can also upload files, from your computer into the cloud right here. There is also a documentation button and that is very, very important. I'll tell you more about the documentation in the next video. I like to keep it open if I work in the cloud because all the answers to your questions about the Wolfram language are right there at your fingertips. If you were able to download a copy of the desktop version, either by a site license from your institution or whether you purchased a copy, this is what you'll see when you start Mathematica. As I mentioned, Mathematica is the coding environment, the desktop coding environment for the Wolfram language. We can open files if they already exist. That's just going to open your normal folder structure on your internal drive, and allow you to navigate to the files and folders that you require, or you can simply just start a new notebook. Let's open that up. I'll increase the size on the bottom here to a 150 percent and there is our blank canvas. A Notebook, the environment in which we are going to write our code. The cloud version of the Notebook, which is the programming lab works almost exactly the same, other than the fact that it exists in a tab, in your favorite browser. That's it, how to get a copy of Mathematica or the programming lab, the environment in which we're going to write our Wolfram language code.
