How to deal with violent nightmares?
Submitted By: wee (10)
I have terrible nightmares.  They are usually not supernatural but mainly me being pitted against someone to fight. They've gotten worse and I've been waking up screaming and/or punching and kicking.  Last night I nearly socked my wife while having a bad dream about defending myself.

 What can I do to overcome this?

Why is the speed of light the value that it is?
Submitted By: Craig (21)
We know that the speed of light in a given medium is a constant and that the speed of light in a vacuum appears to be an absolute limit and that E=mc^2. However, can anyone prove to me mathematically (ie without resorting to experiments that measure the speed of light or deduce it from interference patterns etc) why c is the value that it is and not some other value? Is there a way of deriving c from first principles which shows it to be the only rate that electromagnetic radiation can propagate at in this universe and why? i.e. We can prove without resorting to measurement why PI is the value that it is, can the same not be true for c?

Do you have a cure for the sore throat?
Submitted By: right.h.man (99)

I've had a sore throat for a few weeks now. The doctors tell me its just the flu and to gargle with some salt water.

Its not going away however lol. They've done tests and yes it IS just the flu.

I use mouthwash even and it still persists.

I'm willing to try just about anything really. I would really like to stop this pain. I'll try all of the simplest answers first and report on their effectiveness.

Pharmaceutical Companies Holding Back?
Submitted By: Raptor235 (608)
Does anyone else but me think that pharmaceuticals are holding back with cures for anything?

If you think about how much money is dumped into Cancer / Aids research each year why haven't they come up with anything yet?

If you think how much a billion dollars is and how many salaries it could pay for a year I think any country within a year could find a cure... that's why I think with any cures for any health problems there are some being held back.

They get money from the goverment / charities and then they also charge incredible amounts of money for the drugs ( saying they have to pay for the R&D) I don't know but to me that's really sketchy.

Bridge Building Competition
Submitted By: michaeljh (57)
The bridge building contest I’m entering in consists of putting more and more weight on the model bridge made of pine wood until it goes smashy smashy. You're bridge efficiency is determined by the load it carried before bridge failure divided by its own mass. There is a bucket that hangs down from the bridge where you then put the weights.
The bucket that hangs from your bridge is 2kg and you have a whole mess of weights at your disposal, either 1kg or 0.5kg. Finally, my question: is it good to put the weights in as fast as you possibly can or should you stall just a little bit before putting the next weights in and if so, approximately how long (half a second, a whole second, etc.)?
Anyone working on making a smart monkey?
Submitted By: seanfeld (57)
If we evolved from lower primates and we have made so many technological advances shouldn't we be able to find a way to make a smart monkey by manipulating it's genome or development in some way.  I mean come on everyone loves monkeys and their antics.  I know I for one would love to be able to carry on a conversation with a pimped out monkey.

I'm a researcher who has to track, retrieve, and make use of a large number of journal articles, books, newpaper clippings and websites.  These items are both hard copy and electrinic.

I'm looking what type(s) of systems can be used to build a robust library.  I've got Endnote on the way but am still thinking about the physical (and virtual) organization of the materials.  Any suggestions?

What is the chance of heart disease?
Submitted By: mister.joshua (98)
"Such and such reduces the chance of heart disease by 80%."  "This and that increase the chance of heart disease by 25%."  We hear these statistics so often they've become meaningless, so I'd like to know...what is the chance of heart disease?  One in 10,000?  One in three?  (One in three Americans die of heart disease, so is that what they're referencing?  Is it like charting the chance of death, despite knowing that everyone is going to die?)

Why is it that 2 "instances" added together still makes 1?
Submitted By: Symic (42)
I have been taught that 2 distinct "instances" (i.e. an increadibly small momment in time) when added toghether will produce a single instance, by sheer definition if instance itself,
      However I do not understand how one measure can be added to another identical measure, and produce the initial ammount.
