Why are most people right-handed? Why does the needle on an electroscope go to neutral when grounded? Why do tetrapods have just two pairs of liimbs? Why can dropping a magnet destroy its magnetism? Why is unpolluted air a homogeneous mixture?
and Boeing had to write off three separate mock-ups that were too much like science projects to pass off as airworthy planes. In the end, the Dreamliner (another name for the 787) cost no less than $30 billion, and probably closer to $50 billion.” ...
Today as we look to rebuild, we need to look back to see the mistakes we’ve made, and how we could have done things differently; but the real need is to build a new model going ahead — the one that makes the existing one obsolete. The effects of climate change are all around us...

I estimate around 300 flights, all with the necessary air traffic control clearances, were due to depart in that forbidden hour. Those precious permissions cannot simply be held over for the next hour: American Airlines itself has another 300 planes to dispatch in that timeframe. ...
Inside each business category, of course, are fascinating specifics. The single least localized type of manufacturing is “transportation equipment,” which refers to firms making cars, planes, trains, and the like. This suggests why reducing our dependence on automobiles is an important goal, not...

I went through this roughly 30 times in a single model yesterday, I needed to sketch on small faces of a larger model, and the vast majority of these faces were not aligned with the global XY, XZ, YZ planes. Every single sketch caused the view to swing around until th...
