Many scientific demonstrations are potentially dangerous, and should not be attempted without considerable laboratory experience and appropriate safety precautions. Many older well-known scientific demonstrations, once mainstays of science education, are now effectively impossible to demonstrate to an audience without breaking health and safety ...
This example of design experiments is attributed to Harold Hotelling, building on examples from Frank Yates. [21] [22] [14] The experiments designed in this example involve combinatorial designs. [23] Weights of eight objects are measured using a pan balance and set of standard weights. Each weighing measures the weight difference between ...
