We all use mathematics in our every day lives, be it to a greater or lesser extent. you might add up your change to pay for that coffee, or you might calculate the best value for money when faced with a couple of options, or you might use it to calculate your spending budget for each week. These are all basic uses of maths that can be done in your head or on paper. But what if you need more calculation power? What if you need to calculate and display complex functions? Well, then you need a Computer Algebra System (CAS), and Mathics is one of the best — for free.

Mathics can be used by anybody, but those who use it for more complex calculations, for work or study for example, are the ones who will most benefit from it. They will likely need a way to display, calculate and share their formulae, calculations and workings. This is where comes into its own with an online interface and powerful backend. (more…)

Wolfram alpha has been receiving a lot of attention, and a number of people have seen it as Google’s new rival. In many ways, Wolfram Alpha more than just a search engine – it’s a smart computational knowledge engine.  Anyone who ask Wolfram Alpha factual questions will receive not only facts, but a complete analysis of the questions, with diagrams, charts, and formulas. Wolfram Alpha processes questions through its built-in models, algorithm,  and presents real-world knowledge to users.

In this respect, Wolfram Alpha is smarter than Google. Wolfram Alpha retrieves relevant information, apply scientific models,  and present its answers with data comparison, trends, diagrams,  instead of merely giving you a list of documents that matches your search keywords – like what Google does. The system is elegant, the user interface is simple and clean – it is simply stunning.

No matter what you’d like to learn about, Wolfram Alpha is a great place to start. Here’s how you can use it to learn more about the world around you.
