and even where not, should be ignored. At least in case of conflict. Discuss. In parents' imaginative, somehow at the same time ideal and dismal, worlds there are only engineers, doctors, lawyers and maybe a token economist. Inspired by posts like this I would not even stand too strongly...

I am writing an STSE and of course the last section is the environment section. I suck at this part because sometimes it's hard for me to connect to all categories. So how does a gyroscope relate with the environment? If you know of a small topic on this, please let me know and I can just go...

Hey guys, I was wondering if I could get a little info I'm building a robotic hand for a masters project. I'm interested in looking into actuating some of the joints using a 'dohelix' method, where a flexible plaited cord is twisted by a DC motor on one end to produce a translation on the...

I have this so called in class physics fair and its pretty much a project. But I'm having trouble thinking of a topic that is not of the common ones other people have done. Of course it has to be related to the grade 12 physics course and be within a small range budget? The grade 12 course...

Im getting a little group together to submit some ideas on how our campus can conserve energy, and what would save the school money and energy. We came up with some really cool ideas, but I wanted to see if any of you guys/gals had some ideas, or heard of ideas certain campuses are doing to...

So I'm a third year EE student and we have this thing called a "group project", where we work part times in groups of 2-3 students on a topic. Anyways I have been reading up a bit on plasmonics and I find it very interesting, so I was wondering if anyone might have an idea of some sort of...

For a science project we have to make an ''egg protector''. It has to have: -parachute and -base to hold egg in (I just joined 30 minutes ago and could not find a forum like this. So sorry if this is a duplicate.) Aaaaaanyways, our group has to drop it from a 5m tall height, the...

FQXi was set up to support research gambits with a chance of success but unconventional enough they wouldn't be funded thru normal channels. It has private money. We may be able to learn something by looking at the abstracts (brief summaries) of the grant winners' proposals. Here is the...

Hi Please don't give me another warning for posting in a wrong forum. Seriously, in my view this belong here in "General Discussion" forum. Where I'm placed these days here we have electricity blackouts several times a day, sometimes for as long as 3 hours at one time. My laptop could run...

Hi all! I've been doing a lot of quantitative analysis on research work (PhD) within the social science domain. this has involved extensive identification and explanations on any repeating themes, linkages and whether they relate and patterns between two variables. as part of this I have...

I came across this problem on another forum. Seems to be very tough. The only trivial facts are: m is of the form 4x+3 for n>1 a trivial solution (n,m) is (0,2) for n even, m^m-1 is divisible by 3 for n odd, m^m-2 is divisible by 3 any ideas?

This may not be the best place to ask, but anyways, in class we are doing an independent project. We need to analyse a technological device that uses the properties of gravitational, electrical, and/or magnetic fields (eg. MRI machine, particle accelerator, zero gravity experiments), and explain...

Camera "clicker" I need to take a picture every 5-60 seconds for about 2.5 hours. The problem is, I won't be near my camera when I do that. I want to make something to attach to the "clicker" or whatever it's called on the camera that will click it about that often. The button definitely...
