Perfect model?

scientists at the Bangalore-based Indian Institute of Science (iisc) have devised a new method to forecast the monsoon, that too eight months ahead of the rainfall season. The statistical method, developed by R N Iyengar and S T G Ravikanth, is much less complicated than the existing forecasting models, as …

In interstellar space
