  • People have attached pens to 3d printers and used them to write letters, effectively print. Most consumer 3D printers are useing or based on open source software.

    I think the issue is, printers are relatively cheap to buy and replace. So building your own and programming it hasn’t been necessary. Where as 3d printing was completely in accessible before the reprap movement. 3D printing software is open source as it is motivated by people wanting to build their own machines that could build machines. Something you couldn’t easily buy.





  • This is a common misconception of the placebo effect. The placebo effect is a measurement issue, not an actual benefit.

    Tests are corrupted by using the reposnes and judgement of humans. People will say they had some sort of benefit because of expectations, poor recollection and politeness. It doesn’t mean a benefit was gained. A placebo group allows researchers to quantify how much the placebo effect has on the data they gathered, they can then see if the experiment they did had any effect. Placebo is literally our definition of zero effect.

    Anyone telling you placebo is a good thing is wrong, misinformed or deliberately misleading you. In many countries it is illegal for doctors to prescribe ‘placebo treatments’. They will still recommend such things to their patients - not because they work but because they get the patient out the door and less likely to come bother them again.



  • America tried to modernise many British means of methods and standards. They used a metric currency long before Britain. That’s why they have a cent (1/100) rather than pennies and bobs and truppence.

    They got ride of many terms for multiples of measurements that made the imperial system more similar to metric. Americans use ounces, but they don’t use pounds.

    America also defines their us customary units using metric. There’s no longer an inch. There is a meter and from that an inch is defined as 24 millimeters. This is largely due to British, Canadian and American components for fighting wars not fitting together despite all using the same inch.

    Had America modernised a little later they probably would have converted to metric earlier than Britain.
