Yuri Gagarin gained worldwide fame as the first man in space. But the unsung hero of the Soviet Union's triumph was a brilliant scientist called Sergei Korolev. Korolev remained in the shadows throughout his career and was only revealed to have masterminded the USSR's rocket wizardry after his death in 1966.

Teko is a package for development and implementation of block preconditioners. This includes support for manipulation and setup of block operators. Furthermore tools exist to support decomposition of a fully coupled operator. Additionally, facilities that allow the construction of approximate inverse operators using the full complement of available preconditioners and solvers are available in Teko. Finally, a small number of generic block preconditioners has been implemented in Teko, including block Jacobi, and block Gauss-Seidel. For the Navier-Stokes equation, Teko has implementations of SIMPLE, PCD and LSC. For details on these methods see Stabilization and Scalable Block Preconditioning for the Navier-Stokes Equations and the references therein
The Taliban’s 80,000 troops have retaken Afghanistan with cities falling like dominos while the 300,000-strong government forces, better equipped and trained, mostly melted and surrendered with no will to fight. Why did it happen?
