rickyconnolly | 12 years ago | on: MTU Study: 3D printers may soon be in every home

3D printing is rather useful in the research lab. For example, most biological research labs will have a piece of kit called an electrophoresis chamber. This is essentially a plastic, watertight box with two wire electrodes inside. These chambers will cost upwards of 800 dollars.

I drew up plans for my own electrophoresis chamber in Sketchup, uploaded it to Shapeways (https://www.shapeways.com/model/1240729/sds-page-tank-v6.htm...), and got it printed and sent to me for less than 70 bucks. Wiring it up cost less than a dollar.

By the way, does anybody know of similar services that are even less expensive? Shapeways seem to specialize in making little trinkets and gadgets, so I suspect my rather large, bulky box cost even more than it needed to.

You can find the 'golden' ratio, as well as any other ratio you fancy, within any complex dataset, such as the waveforms of an audio file or the spirals on a sea shell. The golden ratio meme is like numerology, once you know what it is, you will see it pop up everywhere.

A nitpick: the study the article links to is published on Arxiv, rather than an academic journal. This implies these findings have not yet been subjected to peer review. Since the authors have previously stated their support of Rossi, this somewhat detracts from their claim to be independent and academic.

He doesn't want to release the prisoners, he wants to transfer them from military to civilian control so they can be tried in a public court. The later, as I understand it, is beyond the President's remit (but I stand to be shown otherwise).
