I don't know... I'm sure ther's been at least one solipsist here on TOL.
Well
Well
Perhaps we might agree that there is not a single topic on which we all shall agree? A philosophical conundrum of sorts.

I loved that song when I was a kid.

Who on TOL believes that?

I don't necessarily believe it, but I'm not willing to discredit it as a popular theory, especially considering all the research going into quantum mechanics these days.
Although, I do like how you phrase your question in a way that makes the notion of such a thing seem absurd, when in actuality the same law applies to your God.
Agreed! :up:
That TOL is a pretty cool place.
That the earth is round!
I hope. :noid:
Somewhere, somehow, Newman is laughing.
Yes TOL is great, TOL is cool! A bit more profound, there is not anything of subject, we shall have absolute and perfect agreement.
That 2 is unusual because 2+2=4, and (2)(2)=4, and 2^2=4, can you dig that?
Now dig this: In audio amplification, all the pros measure power with single numbers, such as 6, 7, 8, 9 and so on; the reason is that these numbers are the exponent of log base 2; therefore, it is and easy way to determined needed power. For example: suppose a JBL speaker has a sensitivity of 94 db or decibels (log base 10) at one meter; the loudness needed is 109 decibels, each double in loudness, perceived by the average human ear is about 3 decibels, therefore the customer wants 109-94=15 decibels more to in loudness. Now, each 3 DB will demand doubling the power, so, it 1 watt = 94 DB then 2 watts =97 DB, thus every 3 DB increase, the wattage doubles and this is why power is measured on log base 2; however; it is the exponent which is used to measure power, not the base. Now this seems complex, yet once understood, it is very simple; the sound installer is told that he needs to use a 6 power amplifier, because 15/3=5 and 3DB more headroom would equal 6, which is 64 watts, see that 2^6=64. Ok, most amplifiers for this application are 100 watts RMS and the is the one chosen for this application.
Now in home audio, most speakers are less sensitive, say 87 DB at one watt at one meter and the listener does not need anything close to 109 DB, so, say 94 dB is enough, then 97-87=10 and 10/3=3.n, meaning the costumer would choose 4 power, if played conservative or a 5 power to hedge bets; therefore, the customer is shown receivers or amplifiers from 30RMS watts to about 60RMS watts. Now all this is basic audio physics and you know it now.
With box stores, the sensitivity of the speaker is often unknown and the sales person does not know anything, or not much about audio engineering and pairs the customer with speakers based on look and apparent sound, along with an amplifier that is not measures in watts RMS. Just look at Best BUY 5.1 receivers said to provide 100 watts into five channels, then turn the receiver around and look at its watt consumption at the plug; it might say about 300 watts, so where the heck are these 100(5) watts coming from!
