...never satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand. . . ."2 Proteins are the best example of a molecular building block approach to nanoscale architecture....

...never satisfy myself till I can make a mechanical model of a thing. If I can make a mechanical model, I can understand it. As long as I cannot make a mechanical...that is why I cannot get the electro-magnetic theory of light'?1 In Lord Kelvin's time the ether was regarded as material — as a sublimed kind of matter....

...myself," he says, " until I can make a mechanical model of a thing. If I can make a mechanical model I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand." This is one of the many interesting personal touches in the famous Baltimore Lectures, and for these...

...satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model, I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand it." This use of models is indeed to be found in the work of every follower of Faraday. Maxwell designed...

...or do •we not understand a particular subject in physics?' is 'Can we make a mechanical model of It?' As long as I cannot make a mechanical model, all the way through, I cannot understand it." As Silvanus Thompson says: "The use of models has become characteristic of the tone and temper...
