How can we change Maths from being described as boring, tedious and difficult to fun, creative and exciting? One way is to show learners simpler, alternate ways of doing Maths, turning the lesson into a game. This is the objective of the Speed Maths Challenge initiated by Vedic Maths Forum SA (VMFSA) in 2014. VMFSA provides School Maths tutoring to learners in Grade 4 to 12 and offers courses in Vedic Maths (a Mental Maths programme) via an online platform. We wanted to take this a step further

Supponiamo di doverci confrontare con un animale, ad esempio un cane o un lupo (o più in generale con un animale, addomesticato o selvaggio). Secondo Konrad Lorenz il comportamento aggressivo di un cane viene influenzato da due stati d'animo differenti: l'ira e la paura.Si può allora provare a prevedere il comportamento del cane in funzione di quale dei due stati domina: nel caso in cui l'animale è dominato da paura o da ira, proporre una previsione è abbastanza semplice; nel caso in cui il […]

A new clue about the #quarkgluonplasma from @RHIC_STAR at @BrookhavenLabWithin the particles that constitute atomic nuclei, protons and neutrons, there are the quarks, the elementary particles with fractional charges, linked to each other thanks to the gluons, bosons that carry the nuclear interaction. Thanks to the gluons it is impossible to observe, at present, free quarks, but it is expected that in the very first stage of the universe, matter was in a state called quark-gluon plasma.
