Perhaps paradoxically, this meant I was expecting to be a little disappointed: how can a book, by an author…
At work we’ve got a 3D printer. In this series of posts I’ll share some of the designs I’ve made. At the start of the Summer we (I) bought a new 3D printer for the department, a FlashForge Dreamer. It’s got two extruder heads, so it can do two-colour prints. To test that out, I…
At work we’ve got a 3D printer. In this series of posts I’ll share some of the designs I’ve made. The roof of the Sheldonian theatre in Oxford, built from 1664 to 1669, is constructed from timber beams which are unsupported apart from at the walls, and held together only by gravity.
Nice-looking maths & things using maths.
