2 The typeface used here is not intended to limit the discussion to the set of scalars. We are talking about elements in any set. ” But the latter term is not as widely understood, and we could only afford this footnote to dwell on the distinction. 4. 6. 4 Vectors versus Points Recall that a “point” has a location but no real size or thickness. In this chapter, we have learned how a “vector” has magnitude and direction, but no position. So “points” and “vectors” have different purposes, conceptually: a “point” specifies a position, and a “vector” specifies a displacement.

How could your digital audio program know the absolute loudness you will experience, which depends not only on the audio data, but also the volume setting on your computer, the volume knob on your amplifier, the power supplied by the amplifier to your speakers, the distance you are from the speakers, and so on. Sometimes people describe how loud something is in terms of an absolute dB number. Following in the footsteps of Gabriel Fahrenheit, this scale uses a reference point based on the human body.

What exactly do “left-handed” and “right-handed” mean? The most intuitive way to identify the handedness of a particular coordinate system is to use, well, your hands! 2 Your thumb should be pointing to your right, and your index finger should be pointing up. Now extend your third finger3 so it points directly forward. You have just formed a left-handed coordinate system. Your thumb, index finger, and third finger point in the +x, +y, and +z directions, respectively. 12. 2 You may have to put the book down.
