How do you refute a polygraph result? Some guy doesn't like you and just says that this set of wiggly lines means your lying. While what it really means is the guy interpreting wiggly lines for a job is just an asshole.

There is no theory on a polygraph. It is made up. Completely. Nothing about a polygraph is based on science. The guy that came up with this bullshit, also starting hooking these things up to plants and claimed they could tell what your thinking.

You don't need CNC and learning machining is not that hard. You don't make a mold for a one off part either. I got a mill and lathe setup for only 2k. Consider that high end 3d printers are more expensive than that its not bad. These days CNC and high end 3d printers are similar in price. As for cheap 3d printers. Well they are crap. We had one at a maker space, and you basically end up "machining" it afterwards anyway, its weak, inaccurate with an awful finish and the plastic is not exactly cheap.

Normal mechanical design can and does easily deal with this. You may not be able to make it fast with 8020 and crappy 3d printed plastic. But you get what you pay for.

Right now the stereolithography method has become much more viable for this sort of thing. The UV curing resins are now much cheaper and are comparable in price to to plastics used in FDM machines. With modern UV LEDs or laser didoes and a over simpler mechanical construction as well as better resolution. Personally i am looking at making one with a hacked tablet and a UV led array.

Commercial models are still a bit pricey. But the DIY market is starting to get stuck in.

We do know what radiation does. We do know the dose is insignificant compared to want you received from space. It really doesn't accumulate much at all. To be a concern it would need to accumulate trillions of fold increase. It can't do that. And these things have decay profiles on the order of a human life, not geological time scales.

It really is something we do know. For example that bad diet is *way* more of a risk. Driving ever in your life is more risk. We *know* from the *data* that this does not pose any measurable risk at all at these levels.

You guys are getting all your facts out of kilter. Iodine is the one that does the Thyroid thing and it doesn't bio accumulate at all (just take lots of non radioactive Iodine). Caesium-137 get distributed throughout the body and also does not bio accumulate (70 day half life), this can be reduced to a 30 day half life with treatment. http://en.wikipedia.org/wiki/C....

There is a lot of data for the threshold model with ionizing radiation exposure, but because of liability reasons no one is going to make policy with it.

If its a great book, then it won't translate to a movie well at all. Good movies are either written that way from the start, heavily adapted, or only a short story.

The problem with this idea, is that it would make a great food source to the much faster replicating, and therefor evolving traditional life forms.

If the news you get makes you stupid... it is because you are stupid.

bio-fouling happens on moving surfaces as well. It will be expensive keeping them clean.

And now you have some of the most expensive electricity ever.

You would be surprised how much can't be 3d printed. For example even if you can print aluminum, you couldn't print the outside edge of a iPhone. It is forged to get the right set of crystal structure and work hardening to give it the properties it needs.

And then there are electronics and all the different materials you would need. It won't be quite the revolution you think it will be. It is not like they are new or anything.

We do need a good open source cad program. While not cad both these projects (Art of Illusion and Blender) are fairly good. Blender is getting so much work put into over the last few years, and is getting pretty impressive. If they decided to add a "CAD" mode. It would be implemented fairly fast.

Of course even really good free/cheap CAD does not make everyone a CAD designer or whatever. 3D printers at home will do what most printers do at home. Print clip art (other peoples models) or photos (3d scan).

using just a camera you can 3d scan things.

So your measuring your reproductive potential with how much money you have? Well i guess you can afford a lot of blue pills, but last I heard hookers tend to want you to use protection or are on the pill.

It is far better to be happy than wealthy.
