http://quoteinvestigator.com/2010/05/04/universe-einstein/ He is credited to have said it. But what is said does not engage, only what's written does (who said that?). ANYWAY... "more efficient use of the motion" ? Is a simple turning rotational motion of one hand less efficient than...

Do people really need to think about which way to unscrew and which way to screw? Do people prefer using 2 hands than one so that they don't have to think about which way is to screw and which way to unscrew?? Did people got paid to think about such an idea and engineer that device? Do people...

Possible use: - a DJ turntable, with high torque, so you can scratch as much as you want without slowing it down. - a jumping robot. use a piston-system to transform the rotating movement in an alternative longitudilan movement, put a spring mechanism in the end. Think about equilibrating...

And adding last model, using multiphisics for non-isothermal flow, that also does NOT converge

Hello I am trying to validate my model by comparing a simple axisymetric 2D impacting flow of air on a surface. The geometry is simple: a cylindrical (diameter d=26.5e-3[m]) jet of air (debit Speed Ud=13.46[m/s]) is impacting a surface at distance H=0.2833[m]. Flow temp is Tj=20°C Wall...
