The Wolfram|Alpha widgets are mini-apps built on top of Wolfram|Alpha queries. You can easily build your own or use any of the ready made useful widgets found in the Gallery.
These widgets can do just about anything "from calculating the calories in a
recipe to solving complex problems" so long as Wolfram|Alpha can answer the particular query.
There are literally hundreds of widgets to choose from. The most popular categories include Astronomy, Culture & Media, Education, Geography, Health & Medicine, Money & Finance, Physics, Mathematics, Socioeconomic and Weather.
I just love the way intermediate steps and diagrams can be included as part of the answer - see the featured examples below. Gives a whole new meaning to "Bite" sized learning.
I have also included the 'FETAC Grades' calculator, which I created earlier. Go on give it a try. You know you want to....
