The attack takes place at the climax of the blockbuster Avatar: Rockets slam into the Pandora inhabitants’ homeland tree. Explosions, flames and thick clouds of smoke appear on the screen. To keep the audience pinned to the edge of their seats, the images must be realistic. But the simulation of physical processes is especially tough to implement. This includes representation of liquids and gasses, which fall into the category of fluids.

Acoustic Dynamics: Modeling Power Efficiency in the Violin

February 13, 2015 11:16 am | by Jennifer Chu, MIT | News | Comments

Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.
