I guess sometimes you must do the best with what you have I'd like to say (to nobody in particular) the Bible gets it wrong when it says "Blessed are the peacemakers". It seems to me that Peacemakers get attacked by both factions.

Worms have evolved to live on a diet which includes heavy metals. "Newly evolved "superworms" that feast on toxic waste could help cleanse polluted industrial land, a new study says. These hardcore heavy metal fans, unearthed at disused mining sites in England and Wales, devour lead, zinc, arsenic, and copper." http://news.nationalgeographic.com/news/2008/10/081007-super-worms.html

This is something I posted in an earlier thread:= "f you calculate (8-x^3)/(2-x) when x=2 you get 0/0........................... I'll just say I make this example of 0/0 equal to 12........................" Are you suggesting this particular case has two answers?

In the spirit of fairness and balance +1 I am not American so take my observation as an outsider with a pinch of salt. (IMO) A weak America would be a disaster for the world; an honest America would be an asset to the world! Later edit: forgot to activate the promised +1 - have now done so!

I think it represents one man's honestly held opinion and as such surely he should be allowed to express it without neg reps? +1

On the basis that two different scenarios are being considered then I agree that one feels that there should be some small difference. I think we all understand the basics of capacitance but I'll chuck my two pennyworth in anyway. The general theory states that since the dielectric is an insulator no electrons enter or leave it in the charging/discharging process. The material of the plates that cause the changes in the dielectric neither, therefore, add nor subtract to the general consideration of effect on the dielectric. I am ignoring any effect on the time taken for charge/discharge due to plate resistance which is usually considered negligible. I quote from a web page concerning ceramic capacitors and any differences regarding accuracy and frequency response are accounted for by consideration of the dielectric alone. "A ceramic capacitor is a fixed capacitor with the ceramic material acting as the dielectric. It is constructed of two or more alternating layers of ceramic and ametal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefor the application of the capacitors which are divided into two stability classes:" ( Made bold by me) Class 1 ceramic capacitors with high stability and low losses for resonant circuit application Class 2 ceramic capacitors with high volumetric efficiency for buffer, by-pass and coupling applications." http://en.wikipedia....ramic_capacitor An interesting point (which means I don't know the answer ) is what difference would it make if the plates were different polarity silicon (n-type and p-type).

As I understand it he doesn't but he might think you do. You don't but might think he does.

In theory it should not make a difference. The capacitance is determined by the dielectric, the area of the plates and the distance between them. The plate material is not considered a factor. I can only wonder if you think there may be some small difference if ,in bonding the silicon to certain dielectrics, there may be some degree of merging which effectively reduces the distance between the plates a small amount. I've never heard of such a thing. http://www.daycounter.com/Calculators/Plate-Capacitor-Calculator.phtml

Mooeypoo - seems you are giving yourself more of a headache than the person wearing the helmet!

Swansont:- I posted this quite recently - hope you can accept it as a compliment! Joatmon Jul 23, 2012 You should know that the Big Chief Scientific God walks among us. His task to keep us on the straight and narrow path of truth. If you speak his name then do so in hushed tones and reverence. That name is Swansont.

I would say that competition is inevitable and is an essential element of evolution. Whether we can ever stop competition being resolved by violence is a huge question. I doubt we ever will because eventually the competition becomes for the very means of survival such as being able to provide food and water for ourselves, our families, our society and our country.

I didn't think that far. Oh well I expect I can get used to Nun's habits! Much later edit: I have been giving it some thought. Since the question was rarely asked I don't think things are really that bad. Under the circumstances I shall remain optimistic, put my Nun's habit back in the drawer and stop practising for my next life!

I guess 25 - 35 cents isn't wasn't too bad!

There is a problem that has been touched on in other posts, but not really in this way :- A high velocity rifle round can pass through several people, particularly if it doesn't hit much in the way of bone. In the action of bringing down an assassin, particularly if he/she isn't wearing body armour, you may be directly responsible for killing innocent people. This is, of course, even more likely to be true if you are in a crowded space. Also should you miss then innocent people are likely to get hurt or die. I note that marshals on aircraft use low velocity rounds - but believe that is mainly to minimise puncturing the cabin walls. Perhaps also to ensure their bullet stays within their target? Perhaps if we get to the stage where all public venues have armed security guards and gunfire starts the public should be trained to dive to the floor to give the guard(s) a clear view of the source of gunfire? There remains the question of what type of ammunition should be used.

I wouldn't recommend it for bed bugs - especially if you have grazed knees.

There seems to be a great reluctance for Americans to have what we in the United Kingdom have and appreciate - a decent public, free at the point of contact for people over 60, paid for out of taxation, healthcare system. Also there seems to be a strong suspicion that medications supplied to people are foisted on people simply to make a profit for drug companies when you could do equally well, or even better, without them. In particular drug treatment for blood pressure problems has been highlighted as an example. In the UK, where operations and drugs are free to everyone over 60 years old (most blood pressure and heart problem patients) there would be no advantage to the system to prolong more expensive treatment. I would like to describe my experience as I have had surgery and will be on drugs for the rest of my life. I started blood pressure problems in my fifties. To keep it simple I will just say that It was found that an ECG found an abnormal trace that may have been inherited genetically or may have shown I had had an earlier silent heart attack. The trace could not be corrected with surgery so I was prescribed drug treatment. Later I started to get angina attacks and following a body scan I was given a stent in a blocked artery to my heart. Since a major cause of this problem is a build up of cholesterol and since this effect can block arteries to the brain and/or the legs It seems the fact that anti-cholesterol drug treatment was started was a reasonable thing to do. Lately I have been diagnosed with atrial fibrillation. There are surgical options for example ablation or kicking the heart back into rhythm with electric shock treatment. There are risks but I am happy that my specialist prescribed simple drug treatment, to stop blood eddying in my heart chambers from clotting, as I am coping well with the situation. Because of the British system I feel every decision made on my behalf has been based on what was my best option. So I roll on a reasonably fit septenagerian having had several ECG's a few body scans, the odd operation and a lunch box sized container of prescribed drugs I take every 12 hours. From what I read I am glad I live in the UK! I'll just mention, more for fun than anything, I have recently been given a hearing aid which I'm sure is for my benefit rather than "Siemens"

I don't doubt it. You chose to omit the following from my reply (#21) "Who knows? I certainly don't, but I doubt it. Anyway, here's an article you might find interesting " IMO that makes a lot of difference to the general message and tone of my post.

This looks cheaper to buy and cheaper to run:- http://www.gadgetsuk.com/fly-gun-bug-killer.html

Yeah, I think I'd be afraid of you if we met - and I'm pretty sure I do know why!

I've read quite a few articles on the Bermuda Triangle - but thinking it might be a portal to another universe is a new one on me. Who knows? I certainly don't, but I doubt it. Anyway, here's an article you might find interesting:- "A quantum mechanical explanation sees it as a meeting point of parallel worlds that normally exist separately. But an area of interpenetration could make objects and beings from one world cross over into another. " http://www.lifepositive.com/Spirit/Spirit%20centers/Bermuda_Triangle.asp

Well I don't know why I came here tonight. http://www.youtube.com/watch?v=0nQME5Gl7cI&feature=player_detailpage

This is copied from something I put in a different thread which suggests there is more than one universe. "There seems to be evidence that there may be other universes that have bumped into our own universe on four occasions. This seems to me to suggest that they are separated from us and mobile. So what is between these universes (if they exist)?" >http://phys.org/news...-universes.html

Luck does exist, but in this way - you know whether or not you were lucky yesterday, but cannot know if you will be lucky tomorrow. Whether believer or atheist makes no difference to this fact.

<< Matthew 5:45 >> "so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous." Believers and unbelievers get exactly the same treatment so I don't get the point of the question.

When I was a lecturer this is how I convinced my students that the hole apparently moves in the opposite direction to the electron flow. I used to line up a few students as in the diagram leaving a space. The students were electrons and the space a hole. As the students shuffled to the left the class could see the "hole" moving to the right. Electrons have a negative charge and as the hole is attractive to electrons it has a positive charge.
