The polyrhythmic foundation of Tswana pipe melody

This paper proposes the theory that Tswana pipe melody is not initially conceived as melody at all, but is the result of the application of polyrhythms to the fixed pitches of the pipes of the ensemble in accordance with the norms of Tswana harmony

John Blacking: a personal tribute

John Blacking was sixty one when he died on 24 January, 1990. I knew him for the last twenty five of those years: first as one of my teachers, soon as a loyal friend, fmally as a colleague. The boundaries between these were never rigid - not even when I was an undergraduate and he a lecturer (and then Professor of Social Anthropology) at the U Diversity of the Witwatersrand

A4_8 Basil and Ratigan's Critical Clash in the Clouds!

We recreate Basil's DIY balloon airship as can be seen in Walt Disney's 1986 animated mystery Basil the Great Mouse Detective. We determine whether or not Basil could capture the malevolent felon Professor Ratigan by calculating the speed of the balloon airship and comparing it to that of the Victorian airship La France. We calculated a speed of 2.38m/s +/- 0.38m/s which is insufficient to match the speed of La France (6.00m/s). We conclude that Ratigan is the "King of Mousedom''

A4_7 Who's up for a Ride on the Volcano?

Using Bernoulli's theorem for incompressible fluids we calculate the required pressure and velocity of gas and ash in a volcanic eruption chamber needed to propel Manny the mammoth skywards out of a lava-filled crater. We calculate that a pressure of 14.7 MPa, and an outflow velocity of 112.6$ ms^-1 are required

A4_5 Ground Control to Major Steven

We investigated the resultant velocity that Steven from Steven Universe would be accelerated to due to an explosive decompression within a “Moon base”, and if his velocity would cause him to be ejected out into the solar system. Using fluid dynamics and the conservation of momentum, we found Steven's outward velocity to be 96% smaller than the escape velocity and hence would not escape the gravitational influence of the Moon
