We have learned a lot to use Siri as a Voice assistant, but you should know little about Siri's secret weapon Wolfram Alpha integration. It can do something really amzing and surprise you.

The original is Wolfram Alpha an answer-engine developed by Wolfram Research. 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.(via wikipedia) Now you can force Siri to use Wolfram by prefixing your request with "Wolfram." For example, you might say, "Wolfram, what is the square root of 2?" or "Wolfram, graph x-squared plus three."

But there's a lot more that you can do with Wolfram than just math. Here are ten of our favorite Wolfram searches. These highlight the flexibility of this amazing information resource.

  1. Roll a Random Number. Say "Wolfram, random integer." Wolfram returns a random value between 0 and 1000. "Wolfram, random number" provides a 0 to 1 floating point value.
  2. Look up nature facts. Say, "Wolfram, what is the scientific name of a mountain lion?" It's Puma concolor. Rabbits are Leporidae, and Peacocks, Galliformes.
  3. Check upcoming holidays. Say, "How many days until Thanksgiving?" This returns both the number of days as well as a helpful calendar so you can chart out the time until then.
  4. Create a secure password. Say "Wolfram, password." Wolfram generates a difficult-to-crack 8-character password. Scroll down for alternates. If you need a longer password, you can append these together.
  5. Convert text to Morse code. Say, "What is Morse code for horsefeathers?" You'll see the entire sequence laid out for your tapping pleasure.
  6. Check your diet. Say, "How many calories in a small apple?" Wolfram will tell you that there are 75.
  7. Ask out about time zones. Say, "Wolfram, what is the local time in Jakarta?"
  8. Query about your chances. Say, "Wolfram, what is the probability of a full house?" For a random five-card hand, it's apparently 1 in 694.
  9. Have fun with pop culture. Say, "What is the airspeed velocity of an unladen swallow?" or "Wolfram, who shot the sheriff?"
  10. Visualize colors. Okay, I've saved the best for last. If you work with colors, this can save you a lot of time. Say, "Wolfram pound sign E 9 7 4 5 1" (for Burnt Sienna / Tangerine) or "Wolfram pound sign 2 9 A B 8 7" (for Jungle Green). This will also convert the colors to RGB values and look up closely-matching brand colors from Benjamin Moore. Make sure to scroll down to catch all the helpful information.
