ok I think I understand, thank you. from the bright side I hope I just made your tolerance level before you reach grumpiness a lot higher. :D

Click For Summary
Discussion Overview
The discussion revolves around the possibility of altering the dielectric permittivity of materials used in capacitors, exploring theoretical and practical implications. Participants consider various methods of changing dielectric properties, including temperature control, material composition, and potential applications in circuits.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
- Debate/contested
- Mathematical reasoning
Main Points Raised
- Some participants inquire about materials whose dielectric permittivity can be altered through external interactions, such as electric or magnetic fields.
- It is noted that dielectric constant can vary with temperature, although this may not be practical for all applications.
- One participant suggests that mixing powders of different permittivities could yield a material with desired properties, but empirical methods may be necessary to determine the optimal mixing ratios.
- A question is posed about the feasibility of creating a dielectric with a very high permittivity to significantly increase capacitance in capacitors.
- Another participant mentions Barium Titanate as an example of a material with a high relative permittivity at elevated temperatures.
- Participants discuss the concept of a capacitor functioning as a charge pump and the implications of varying dielectric properties on charge flow and voltage in circuits.
- Concerns are raised about the energy implications of changing capacitance and the need for a mechanism to facilitate changes in dielectric properties.
- Some participants suggest that a variable capacitor, such as a Varactor diode, could achieve similar effects, but with limitations on frequency and capacitance values.
- There is a discussion about how varying dielectric properties in a circuit may affect charge flow and voltage, with no clear consensus reached on the outcomes.
Areas of Agreement / Disagreement
Participants express a range of views on the feasibility and implications of altering dielectric permittivity, with no consensus on the practicality of such materials or the specific outcomes in circuit applications. The discussion remains unresolved regarding the exact effects of changing dielectric properties in operational circuits.
Contextual Notes
Participants acknowledge the need for further exploration of the mechanisms involved in changing dielectric properties and the energy implications of such changes in various circuit configurations.

It's like water on stone - you get to me eventually.

Are you familiar with the 'beans' sequence in Blackadder?

I just looked up the show , sitcom apparently , well no I was not aware of this, but I greatly appreciate and personally like many of Rowan Atkinsons works, Mr. Bean would be probably the greatest , also some of his tv fun stuff before the Mr.Bean era.
I just put Blackadder on my downloads , will check it out, thanks.
So what the sequence is about ?
I hope it's not about those kinda unpleasant words written in the premise : http://en.wikipedia.org/wiki/Blackadder
:D

Ah. Different TV culture.
Lord Blackadder is trying to use a discussion about beans to teach his manservant Baldrick, arithmetic. Baldrick is only interested in beans as something to eat. You have been, similarly ignoring the Maths in favour of a chat and some arm waving. He is constantly criticising poor Baldrick in every episode. Baldrick always tries his best.

Oh I see, well I'm not good at maths so whenever one doesn't speak about QM or some other math heavy things , I try to talk in language which is called common english :D
I no doubt agree that math would be better but I think one can undersatnd caps without it too, their not that cpmplocated.I do realize that this statement probably made you loose some of your hair at the very instant you finished reading it. :D
i promise if i ever will get lucky in making some device , I'll denote money to your hair restoration. :)

The fact is that Capacitors and the rest of electrical circuit work is complicated. The only language that describes most electrical phenomena well enough is Maths. In fact, the whole of Science uses Maths and has done since the time when Newton, Leibnitz and others started to get it systematised. Refusing to use Maths will pretty soon end up with that bridge collapsing or a fuse blowing. That's not to say you can't do construction projects and have success. But understanding what happened would be another thing altogether. 'Common English' doesn't put up satellites or make your computer work.
Your English is really fine, btw. I could not hope to discuss things to such a level in any other language as you are doing in English. I can socialise OK in French but it would be hard to get across any Science concepts.
I'm looking forward to receiving that cheque in the post. I will go straight down to the hairdresser's and sort out a wig for myself when it comes.
