Take a speculative subterranean journey through Earth's crust. An imaginary remote sensing vehicle circles the planet, travelling over 55,000 kilometres from South Africa to the Atlantic Ocean as it uncovers some of the treasures the crust has to offer. Biochemist Esta Van Heerden discovers life in the crust in the Tau Tona gold mine in South Africa. Planetary geologist Jim Head explains his new theory to explain the enigma of how diamonds, normally found in Earth's mantle, make their journey up into the crust. And Peter Schultz, of Brown University fires a projectile from a 12 foot gun to investigate what happens to the crust when hit by an enormous asteroid.
From birth to weaning, from territorial disputes to courtship and mating, from brush fires to drought, gum trees are what determine a koala's success or failure, survival or mortality. This film will explore the remarkable bond between the koala and the eucalypt trees it so depends upon.
Steve Morse's almost mythical musical capabilities need no introduction. Marrying blazing chops to a singular sense of hook writing creativity, his distinctive brand of rootsy American virtuosity has inspired generations of players to think outside of the pentatonic box. Morse is renowned for reeling off what he calls "un-guitaristic" lines of seemingly impossible complexity. These keyboard- and fiddle-inspired trademark phrases often consist of no more than a single note on any given string. This kind of one-note-per-string arpeggio picking is typically regarded as the domain of fingerpickers, not flatpickers. Yet the effortlessness with which Morse nails these gymnastic routines is the obvious clue that something mechanically magical is happening under the hood.
