Sage, also known as Tessa, is a fictional character in the Marvel Comics universe. She has most often been associated with the X-Men and the Hellfire Club, whom she spied upon for Professor Charles Xavier.
A mutant, Sage possesses a number of mental abilities and was originally presented as the personal assistant to the Hellfire Club’s Sebastian Shaw, but an extended retcon revealed that she was one of the first mutants discovered by Professor Xavier. She has been a member of the original X-Men teams, the Excalibur, the Exiles, and a cross-dimensional X-Men team similar to the Exiles known as the X-Treme X-Men.
Tessa first appeared in The X-Men #132 (April 1980), and was created by Chris Claremont and John Byrne.
Sage's exact country of origin remains unrevealed, but she claims to have come from a war-torn region. By the time she reaches young adulthood, she is living by herself in Afghanistan. Although she tries to keep out of the conflicts between the rebels and the government, she is willing to use her guns and other weapons on anything that poses a threat. One day, she feels called to a cave which is considered haunted by the locals. She hears a voice in her head that guides her deeper into the cavern, where she finds Charles Xavier, who is trapped underneath a pile of debris. His legs have been crushed during his battle with the alien Lucifer. Xavier senses that Sage is a mutant, and explains to her what her abilities mean. Sage says that this was about the same time as he located Beast, but in other accounts he found Sage first.
SageMath (previously Sage or SAGE, System for Algebra and Geometry Experimentation) is mathematical software with features covering many aspects of mathematics, including algebra, combinatorics, numerical mathematics, number theory, and calculus.
The first version of SageMath was released on 24 February 2005 as free and open source software under the terms of the GNU General Public License, with the initial goals of creating an "open source alternative to Magma, Maple, Mathematica, and MATLAB". The originator and leader of the SageMath project, William Stein, is a mathematician at the University of Washington.
SageMath "uses a Python-like syntax," supporting procedural, functional and object-oriented constructs.
