Top 10 things you can do with Wolfram Alpha

After some research of Wolfram examples I have find those 10 most interesting examples to share with the world. Some examples are useful and some are interesting. Examples are sorted by relevance. First example is most interesting and so on.

1. Get data about recent earthquakes - really impressive, you can see earthquakes in world map in last 24 hours (or broader time interval) by magnitude.
   
   Example : earthquakes
   
   To see you need to type earthquakes in wolfram alpha






2. Get salary data for a given occupation - Enter word salary and occupation. You will get salary data for entered occupation (median wage, history, people employeed ...).
   
   Example : salary progammer
   



3. Generate report for life expectancy - You will get median life expectancy, highest(with country)life expectancy, and lowest life expectancy. There are also life expectancy rankings by countries and more demographics data


Example :


• life expectancy


• life expectancy in Andora




4. Rank countries - you can rank countries by some criteria


Example :


• 5 richest countries


• 5 poorest country


You get first 5 countries by GDP per capita, by GDP and by poverty fraction.





5. Country comparison - compare two countries (by location, area, demographic data, economic)
   
   Example: America, India



6. Find the definition of a word - enter definition and word you want to define
   
   Example: define soldier
   
   Result: soldier - serve as a soldier in the military



7. Find words matching a pattern - write word and with exchanged letters with low line. This can be very helpful if you can't remember the word.
   
   Example: _oun_e_
   
   Wolfram will return:
   
   b | o | u | n | c | e | r
   b | o | u | n | c | e | s
   b | o | u | n | d | e | d
   b | o | u | n | d | e | n
   b | o | u | n | d | e | r
   c | o | u | n | s | e | l
   c | o | u | n | t | e | d
   c | o | u | n | t | e | r...




8. Find anagrams of word - type "anagrams" and desired word
   
   Example : smart
   
   Wolfram will return : marts and trams
   



9. Compute a time difference - type Date to Date and you will get time difference.
   
   Example: Mar 21, 2009 to Sep 7, 2009


Wolfram alpha return 5 months 17 days


10. Do a mortgage computation - you can calculate monthly payments, mortgage totals and payments and balances. Very nice.
    
    Example: mortgage 100,000 Euros, 7%, 25 years
    
    

Wolfram Alpha (also written WolframAlpha and Wolfram Alpha) is an answer-engine. It is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer as a search engine might.

My main objection on Wolfram Alpha is that I couldn't find list for some term. For example I wanted to get list of all occupations but didn't find a way. If you enter pharmacist in Wolfram it knows that it is occupation. Same thing for animals, dinosaurs...

Of course Wolfram Alpha can do many other things but those I found most interesting.
