Just because two waves can cancel each other that doesn't mean they are opposite, cosine isn't the opposite of sine altough you could say they are if they are in the same phase...but as you know no one would say cosine wave, it's always sine wave plus phase. So it would be silly to say the opposite of sine wave is a 90 degree phase sine wave don't you think? But they would still cancell each other (they have opposite signal in their magnitude, but they aren't opposite things). You can't increase lack of heat, as there isn't "COLD" in physics, there is just more or less heat. And on the link you said I'll read it... but it could only mean that 273,15C was the wrong absolute zero. Like time, temperature have no sense being put in a negative scale when you have an absolute zero as minimum point... but sure we could create the VGC temp scale that would have it's zero at the middle point of absolute zero and absolute maximum (whatever it may end up being, maybe 1Million K) and then we would be close to -499.750 degrees VGC at the moment. But having the 0 on the middle wouldn't make the extremes of the scale opposites... Things in nature aren't necessarily opposites, it's just that for human brains the concept of opposite is easier to understand. |
"so you can't say exponential or any other curve is the opposite of straight just because they aren't straight."
i didn't i was asking you to give me an example but anyway i would think the opposite of any line infinite or not would be its inverse
"Just because two waves can cancel each other that doesn't mean they are opposite"
well actually it does
"cosine isn't the opposite of sine"
i didn't say it was i said that to cancel a sine wave you use a wave with the same magnitude and frequency but 180 degress out of phase or in other words you use the inverse of that sine wave or its opposite
"So it would be silly to say the opposite of sine wave is a 90 degree phase sine wave don't you think? "
well i didn't you brought up cosine waves not me
to clarify no cosine waves cannot cancel their sine waves however the inverse of sine waves cancel sine waves
"Things in nature aren't necessarily opposites, it's just that for human brains the concept of opposite is easier to understand."
well yeah i can't disagree that we have to use concepts to interpret reality with and those concepts have to be discarded or changed wiith time as we gain more understanding
