A very useful utility for genealogists is the WolframAlpha Computational Knowledge Engine found at http://www.wolframalpha.com. I use it for all kinds of calculations related to my family history.
It’s as simple as typing in a question, and getting answers. The site calculates things. Following are some examples – simplified for my purpose here. Sometimes the answers are pretty detailed – like how many minutes (or seconds) have passed since my mother’s death – assuming I entered her date of death in the search engine.
- How far is it from Victory, New York to Brighton, New York? 47 Miles
- What day of the week was April 13, 1950? Thursday
- How large is Pierce County, Washington? 1806 sq miles
- What date was the first Thursday in April, 1852? Thursday, April 1, 1852
- Father’s grandmother’s daughter’s son’s daughter – second cousin
The following two example categories for WolframAlpha are very applicable to genealogists.
