Though it's been around for three decades, 3-D printing has finally started to take off for manufacturing and even for regular consumers.

Pope Paul VI hands Orthodox Metropolitan Meliton of Heliopolis a decree during the December 1965 session of the Roman Catholic Ecumenical Council in Vatican City. The decree cancels excommunications that led to the break between the Roman and Orthodox churches nine centuries before.
When Pope John XXIII announced the creation of the Second Vatican Council (also known as Vatican II) in January 1959, it shocked the world. There hadn't been an ecumenical council — an assembly of Roman Catholic religious leaders meant to settle doctrinal issues — in nearly 100 years.
"Many people maintained that with the definition of papal infallibility in 1870, councils were no longer needed. So it was a big surprise," Georgetown University professor Rev. John W. O'Malley says.

In the end, it's the only area that counts: the Electoral College. Over the past 20 years, Republicans have had a much lower ceiling when it comes to electoral support, while Democrats have had a significantly higher floor.
