What are the things to try and control when attempting to burn a high quality audio CD for my CD player in my truck? I am sure there is a bit rating on the file, but are there other things that I can change to get better quality out of my burns? Do better quality CD's make a difference...

Years ago i bought two Ralph Loren (spelling) shirts they are still going strong but are a bit faded, they are made from real tough material and have good length tails. Also 501 button jeans, i can not find them in Uk do they sell them in the USA.

A quick one for you sparkies... There are a ton of FM transmitters you can use to pipe your iPod or other device over your FM stereo. There is one thing in common to the three units I have tried that is very annoying. I have noticed that there is very poor sound quality for the higher...

Best quality oils I know extra virgin olive oils are one of the best. What other oils are of that quality and not needing to be cooked?

Working through my lecture summaries, I have been given that Q (the quality factor) =\frac{2\pi}{(\Delta E/E)cycle} and accepted this as a statement, taking \((\Delta E/E)cycle} to mean the 'energy loss per cycle'. The notes carry on to say 'The frequency \widetilde{\omega} of...

This is one of my favorite boards on PF, but it doesn't have a lot of posts, and I do not know enough about history & historical humanities to ask questions or make many posts. Are there any quality forums that I might like?

[SIZE="3"]"Distances among galaxies in clusters on average are no greater than their diameter". Luminosity, color, and other qualities are used to obtain distances - and these values are connected to masses that are observed by motions. If a system is in equilibrium then the theorem is...

I was at the mall the other day and I walked past the watch store. I always wanted to know what makes a Rolex so expensive. I know they are made out of real gold and diamonds, but there are some nice rolex watches that are all steel with none of the bling. But those are equally expensive, why? I...

So, I did my research when choosing schools to the best of my ability. I picked a school that was listed in the top 50 schools. I visited the school a few times, talked to some students, researched online, and in publications, and decided. Well, I have been here a few quarters, and I am...

How to become a quality physicist? Hi I am a 21 year old male. Im studying in final year of electronics engineering. However my true love is theoretical physics. I read a lot of graduate level physics textbooks however i can digest very little. as a result of which i have become extremely...

hey was wondering Which are the best Fighters in the world ? An american F type, a Dassault, or other ? Which are the best tanks in the world ? Which are the best attack subs in the world (those to attack sea, and those to attack ground) ? Which are the best Nuclear capability subs in the...

Correct me if I'm wrong. I've always taken it on faith that the switch to frequency modulation from amplitude modulation resulted in the much better quality signal and listening experience we have today. Modulation of the frequency is likely less susceptible to distortion than is modulation...

I read that the higher the temperature of a substance (for example gas) the higher the quality to extract work from it. But for the same substance, at same temperature, it would have high entropy as well which accounts for disorderness and hence less availibility of energy. Please help me...

which brand magnet wire is considered the highest quality, Belden seems to come recommended, any others would be appreciated

Why is that i always see and hear people complaining about textbooks? It is true that there are many bad textbooks but why do they buy them? Can't they read reviews or ask around like i do? Also there are many good textbooks and as a self learner I think my opinion counts for something. A...

I need some help deriving the quality factor in an rcl circuit Q=Lw(sub 0)/R. So far I know that Q=w(sub 0)/delta but my professor used this formula to continue the derivation delta w=R/L and I don't know where it comes from. Can anyone give me a hint?

One of the most difficult topics several years ago was weak acid and weak base equilibria and associated mathematical determinations about them in quantitative chemistry. Our class spent a month and a half just studying equilibria of weak acids and weak bases and their buffers, pH's, titration...

My idea is : electricity can be transferred 100% into heat. Mechanical energy can be as well. But heat can not be transferred completely into electricity or mechanical energy. From that point of view, I think that electricity and heat and... are all some forms of energy, but the quality of each...

what does the soundwaves of a poor quality sound look like?? and richer quality?

Another question. If your given the quality coming out of the turbine. Why do you use say H2 = Hl + xv(Hv - Hl) to determine a xv even though u hav one given?

Help please, is there such a thing as a wireless web cam that i can just use with out any mods or additions to my desk top? I need one with good picture and audio quality, and i need it to work 4yrds from the desk top. If there is no such thing can some one recommend a standard one for up to £50?

Hi all, Does anyone of you know the ways in which dose administered to a patient can be minimised while still obtaining a useful X-ray image ?

The reason why this thread is here instead of the Earth science files, will be clear in the last sentence In the spring of this year I received a discussion-group E-mail with an early draft of this paper: http://www.pnas.org/cgi/reprint/0606291103v1.pdf Emphasis mine. As a reaction...

Is good design one of the greatest factors of high-performance technological products?

A friend of mine has given me a link to an amusing movie clip that was supposedly shot on a Nokia N90 but the video quality is so good I believe that its been 'enhanced' afterwards. He swears that the N90's video quality is the best available at the moment but I still think its been doctored...

Someone here has worked out a way that applies to physics: http://math.ucr.edu/home/baez/crackpot.html Anyone wishing to try and apply it to maths? I think it will be an easy transition :smile:

How loud does brown noise have to be for it to be effective?

Hi everyone, Can you please tell me some good reading material on solid/ applied mechanics available on the internet? i want downloadable links or may be good informative internet sites where i can get basics of solid mechanics and applied mechanics. Hope someone helps. Thanx.

Hi all I read that Q,the quality factor of series resonant circuits is wL/R ------------>1/R sqrt(L/C).This i understand 1.but for parallel resonant it is R/wL...hmm but why is that?this i don quite get. 2.Then what do u mean by loaded resonant circuit and unloaded resonant circuit...

I asked a few months ago but didn't get a response so i'll try again :) I'm considdering going to USA for one year as an exchange student, but i must admit that my motivation for it is less then academic. I'm picking it almost solely because i want to train in USA, and my coach there has a...

What is the difference in quality between DVD and VCD? I don't notice that the main difference in image clearence quality.

Goodbye cruel world... *BOOM*

Hi, This is not a physics question. However, I was hoping someone could help me. A call centre sets a quality target of answering the telephone within 30 seconds. The results of monitoring show a normal distribution with an average answer time of 28 seconds and a standard deviation of 2...

ok I'm not so sure if this topic is exactly where its supposed to be...in the biology section! :redface: oh well but the topic of the pics I'm looking for is called: "the relationship of living things and their environment" ...lol does anyone know where i can find high quality/ high...

I have a question. If there are 2 (only 2) big speakers at opposite ends of an outdoor stadium, will the sound be good? Can you explain this in terms of physics. Thank you!

215 cities were investigated to see which one is the best to live in, well: Calgary, Canada apparently :) right above Honolulu and Helsinki :) Amsterdam is on no. 10, like last year (traffic is the big stumble block.. tell me about it :P) Athene is the most unhealthy city of Western Europe.
