How to Ask Siri for Facts
Siri, on your iPad, uses Wolfram|Alpha and sources such as Wikipedia and Bing to look up facts in response to questions, such as “What is the capital of Kansas?”, “What is the square root of 2003?”, and “How large is Mars?”
Wolfram|Alpha is a self-professed online computational knowledge engine, which means that it’s more than a search engine because it provides specific information about a search term rather than multiple search results. If you want facts without having to spend time browsing websites to find those facts, Wolfram|Alpha is a very good resource.
Just press and hold the Home button, and ask your question; Siri consults its resources and returns a set of relevant facts.
You can also get information about many things, such as the weather, stocks, or the time. Just say a phrase like one of these to get what you need:
“What is the weather?”
Siri shows the weather report for your current location. If you want weather in another location, just specify the location in your question.
“What is the price of Apple stock?”
Siri tells you the current price of the stock or the price of the stock when the stock market last closed. (Let’s hope that you own some.)
“What time is it?”
Siri tells you the time in your time zone and displays a clock.
