A couple of weeks ago, I watched the excellent Marvel film Black Panther which has just broke $1 Billion in the box office worldwide!
The film had a number of themes including the question – What if an African country, named Wakanda, lead the world in technology? The film offered a cinematic picture of this, with an important emphasis on the STEM subjects.
Now one of the most interesting characters in the film is Shuri. Wikipedia describes the her character like this
Shuri the princess of Wakanda, designs new technology for the country. She has “an innovative spirit and an innovative mind” who “wants to take Wakanda to a new place. Shuri is a good role model for young black girls as well as being one of the smartest persons in the world.
Now one of the technologies that Shuri design was Black Panther’s suit. The suit can distribute the kinetic energy from an impact. The idea is that the kinetic energy will not be focus on one area but move to another part of the suit where it can be absorbed. Okay, nice Hollywood science fiction stuff or is it? Watching this scene took me back to my postgraduates days, when I was doing a MSc in Industrial Mathematical Modelling at Loughborough University. Here, I did a dissertation on the “Impact on an Adhesive Joint”. Here I had to created a mathematical model of how material behaved in aggressive circumstances. My secondment was at a Material Start up firm ran by three PhD material scientist. They had this crazy idea that if you create a design a composite material, it would be able to take an impact, by distributing the kinetic energy away from the impact zone to places for which it can be absorbed. Sounds familiar? My dissertation, was to create an analytical mathematical model to describe such behaviour. The composite material would be bonded together by adhesive. The figure below shows the schematic.
The Impact Force was represented by a triangular pulse forcing term of impact duration ‘a’.
Now was interesting in the film, Black Panther suit, made up of nanomites started to disintegrate when it was hit by a sufficient force, like the horn of a Rhino or a point blank grenade launcher. The sharp energy rised forced the nanomites apart. Okay not so Hollywood, but in my dissertation research it was identified that the interface is where the composite material was most likely to fail.
However, if the interface remained in place, the adhesive layer serves as the entity to absorb the energy by bouncing the reflective wave between its boundaries. So theoretically, a Black Panther suit could work! Well done Shuri !
This was one of my first mathematical models, and the dissertation did receive a distinction. At the time of thought the idea of a impact absorbing composite material as crazy but after watching Black Panther, it motivated me to have another look at my MSc thesis. Though I don’t think I can invent the Black Panther suite, I hope that this film inspires children all over the world to greater and better things in STEM.
