I once worked at a company where the bulb in the projector burnt out. For some reason that bulb became a weird symbol of thrift so the bulb was never replaced. The company would do a summary of the financials for the year for the employees. Since there was no projector the president rounded up all the whiteboards, uncapped a marker and just started writing. Since he was intimately familiar with the numbers he could talk as he wrote about what what they meant with respect to what was happening both inside the company and in the external business environment the company existed in. It was the best presentation of that type I had ever experienced. So not just maths and physics...
