## √-1

ROOT enables statistically sound scientific analyses and visualization of large amounts of data: today, more than 1 exabyte (1,000,000,000 gigabyte) are stored in ROOT files. The Higgs was found with ROOT!

As high-performance software, ROOT is written mainly in C++. You can use it on Linux, macOS, or Windows; it works out of the box. ROOT is open source: use it freely, modify it, contribute to it!

Living at ROOT's bleeding edge, with Conda (19 Aug 2020)

Sometimes ROOT users get bitten by nasty bugs, and we ROOT developers try our best to squash them as quickly as possible. New features and improvements are also constantly merged in ROOT’s main development branch, either coming from ROOT developers or as contributions from the community. Be it bug fixes or new features, however, users typically have to wait for a ROOT release that includes them to try them out. Or, you know, compile the very latest ROOT from source code – but nobody has time for that!
