i read somewhere that electrolysis of urea solution can produce hydrogen, but what are the other products?

in the 007 film 'the world is not enough' a man is killed by exploding money. it is later explained that the money had been dipped in urea, and one of the metal strips in the money had been replaced with magnesium, and the man had a radiotransmitter on him which set it off. i am a bit sceptical and would like to know if this would work... firstly, wouldn't it need to be in a sealed container for it to explode? secondly, would the magnesium strip ingnite from a radio transmitter? and if so wouldn't it ignite from all the other radio signals travelling around MI6's headquarters?

As our society moves towards energy independence, the importance of renewable resources is highlighted. With the energy needs growing, it has become essential to be more energy independent. Solar energy can prove to be an ideal source of energy. Solar power can be used in many ways and is more efficient, environmentally friendly and available aplenty. With the rise in popularity of solar power, there is also a rise in the companies offering solar power equipments as well. The solar companies have increased in numbers owing to the popularity of the energy. The environment friendly nature of the solar energy has made it a popular choice for many. Moreover, solar energy…

...it does make a sound. Why? The universe doesn't need our presence for its laws to function. How do I conclude that? Because the universe has existed longer than our fossil record indicates. And sound waves do occur without the presence of a biological listening apparatus. It can be tested: just place a glass chalice along with a machine that emits a high pitched electronic sound deep into the woods away from human ears, come back and observe if the glass shattered. Voilà

How to prepare effectively for an exam 1. Make sure you will collect all lecture notes and related material at least 2 weeks before the exam. After that this task will be almost impossible to complete. 2. You DEFINITELY need to get some past papers for this exam. Usually you can get them from the library, university web site or from your own tutor. In some cases past papers may be accompanied with answers. 3. 1-2 weeks before the exam talk to your tutor and ask him or her what kind of questions there will be on exam. In 70% of cases you will receive very valuable information which will significantly help you to prepare. Another important aspect is the…

Is there an implicit age limit for mathematical productivity?

To all of you guys, what science means to you ?

0h7V3Twb-Qk Sometimes it's really hard to gauge how China's economy is actually doing, especially when you see things like this. The discussion of how building an empty city affects their GDP is a very strange one as well. It was also weird to read that while this city is unoccupied, most of the property has been sold to people who are holding it as investments.

So, I've been having a health problems as of late. It started about two months ago. By most standards, people will eventually feel better in two weeks from a generic virus and whatnot. However, I have been having complications for about two months. Two months ago, I went into a doctor about this breathing problem I had. I thought that perhaps it was asthma or some kind of lung condition. I thought it might be lung failure. Basically, I keep having this need to take deep breaths of air. And the action is quite involuntary. I'm pretty sure it's involuntary and not psychological. I don't think it's occurring while I sleep. I could be wrong. But when I wa…

You know how some guys always date the same kind of looking girl? Do you? What do you think about this? If you do, do you understand why you gravitate toward a particular look? Go into detail about why...is it a certain ethnicity you're attracted to, etc.

Neutralizing the 'F' word: at 'Fork University'. -------------------------------------------------------------------------------- The two combined words - 'F U!'; as they are expressed in anger or derision, are in fact the most used insult projected in the American idiomatic language. On the other hand, the 'term' is rarely addressed in an objective, unemotional, academic manner, where and when clear heads and emotions prevail. Instead, the (often exclamatory) 'expression' generally succeeds in clearing an abruptly silent passage for itself, that conspicuously cuts through any discussion of it's intrusive motivation, import, or the fact that it is a princip…

is much more a record of Adams's introspection than of his deeds. It is an extended meditation on the social, technological, political, and intellectual changes that occurred over Adams's lifetime. Adams concluded that his traditional education failed to help him come to terms with the rapid changes of his lifetime: hence his need for self-education. The organizing thread of the book is how the "proper" schooling and other aspects of his youth, was time wasted. His autobiography is a description of his search for self-education through experiences, friendships, and reading. The Education of Henry Adams purports to be the autobiography of Henry Adams(1838-1918). I…

As of 11/6/09, the Army psychiatrist, Nidal Malik Hason, has not only killed and wounded dozens of people at Fort Hood, Texas Army Base, he has cast another ominous shadow on what was already - since 9/11 - a very controversial issue; reintroducing fragile questions, including religious undertones - as they relate to (well intended and otherwise motivated) Muslims in America, and activating questions regarding America's motive(s) for armed presence in the Middle East. Very unfortunately, this appears to be a pejorative problem, for which there is no easy solution. Vets and apolitical citizens are being blamed - and are suffering and dying for - questionable executive …

DHYp8tIOprA I think adults should be able to read, hear and see what they want...... unless it's something like child porn.

I've always had a theory that there are certain things that the human mind is simply not able to have even a conception of what they are like; so far I have been able to think of three; I call them the ultimate unknowns of perception. 1) What it is like to be dead. 2) What you would "see" if you were born without eyes, optic nerves, etc. 3) Visualizing a true higher dimensional space. ie. more than 3 dimensions. Can anyone think of any more "ultimate unknowns"?

I am considering to buy a microscope. I need help; my budget is 350.00. If you would, please direct in the right direction.

http://en.wikipedia.org/wiki/Here_Comes_Science Just saw these guys last night... they've kind of been in my collective unconscious since I saw Particle Man on Tiny Toons, but I saw their YouTube videos for their latest album, Here Comes Science, and they're pretty awesome. What's especially awesome is they released a follow-up scientifically correct version of " ", called Why Does The Sun Really Shine? (The Sun Is A Miasma of Incandescent Plasma): sLkGSV9WDMA So yeah, some science-loving nerd rock there for ya. As I understand it, the original song is actually a cover of an educational song from the '60s, so no fault to TMBG on that one, because the so…

Part 1: http://video.google.com/videoplay?docid=-8492625684649921614# Part 2: http://video.google.com/videoplay?docid=-1663091361786740235# Dangerous Knowledge is a documentary about the lives of four mathematicians/scientists: Georg Cantor, Ludwig Boltzmann, Kurt Gödel, and Alan Turing. The central theme is one of the discovery of the undiscoverable, and being driven mad by it. For example, Cantor was almost driven mad by his continuum hypothesis. Later Gödel attempted to prove the continuum hypothesis himself, and almost went mad trying to before managing to prove it unprovable. All in all it's a very good program and I highly suggest you watch it.

I was just wondering how some of you got interested in the sciences. To start out with, when I was about six years old my mom and I made little water molecules useing toothpicks and marshmallows. I thought that was so fun, I started to read my dads chemistry books.

when you electrolyse water, does the oxygen at the anode stay as atomic oxygen (O) or combine to form molecular oxygen (O2)?
