There is yet another way to convert a degree value to radians for our use in the SIN function. We remember from our time in school that π = 180°. So, if the angle is in degrees, multiply it by π/180° to convert it to radians. In Excel, this conversion can be written PI( )...
This question ties into how elephants maintain “stability” (a fraught term in science). Stability is clearly of great importance to giant land animals following “the bigger you are, the harder you fall” principle. Compared to walking with vision, blindfolded elephants were able to keep the ...
This all began with my 2002 paper in Nature, which at the time was a “new” application in palaeontology of methods that were well over 30 years old then (inverse dynamics analysis of musculoskeletal mechanics), and owed a lot to simpler approaches by RMcNeill Alexander and others, but pro...
