Most areas of human thought are wrong because they assume they're right. Science is mostly right because it assumes it is wrong. Most ways of achieving things fail because they assume they'll work. Engineering mostly works because it assumes things will go wrong.

I tweeted this morning about the possibility of making an open-source oxygen concentrator. I've now had an initial look into the problem, and it seems quite solvable. We ( @RepRapLtd ) have done an initial block design and specified the major components. See this: #coronavirus

We have started work on an open-source oxygen concentrator, as this seemed like a good idea given the World's #covid19 problems. For initial details see our blog:

It is difficult to do a rant without any exaggeration or untruth at all, but here @JonathanPieNews manages just that.

Boeing use to be one of best aircraft manufacturers in the World. That was when the financial people lower in the company had to answer to the engineers at the top. Then, over two decades ago, the financial people were put in charge of the engineers. Now it's a basket case.

Dear FAA, It seems like you should spend more of your scarce resources investigating Boeing and the decaying of America’s legacy aviation infrastructure, rather than SpaceX. The past is crumbling around us while the future is being throttled. Sincerely, A loving American 🇺🇸

This 0.75 Kg object is being accelerated on a low friction surface by just a beam of light. The secret is to bounce the beam between mirrors at either end to multiply its effect.

When I started #RepRap I thought it would lead to the #3Dprinting of a much wider range of materials. I hadn't expected the success of using clay, pioneered by @UnfoldOffice .
