"Mortgage rates" is a trending search topic following the release of Freddie Mac's(FMCC_) weekly survey which showed that the mortgage rates held steady below 5%. The 30-year fixed rate came in at 4.88% on Thursday, up slightly from 4.87% one week earlier, and down from 4.95% a year ago.
"Pi Day" is a hot search topic because Monday, March 14, is the day that we celebrate the mathematical constant Pi, which is equal to roughly 3.14.
Physicist Larry Shaw created Pi Day in 1989 at the San Francisco Exploratorium. Shaw and his fellow staff members made a tradition of marching around the building and eating fruit pies.
