		The verb is first recorded c.1380, with sense "to immerse;" meaning "take soundings with a plumb" is first recorded 1568; fig.
		"on the plumb line," from L. plumbum "(the metal) lead" (see plumb), of which the weight at the end of the line was made.
		perpendiculer, from L. perpendicularis "vertical, as a plumb line," from perpendiculum "plumb line," from perpendere "balance carefully," from per- "thoroughly" + pendere "to weigh, to hang" (see pendant).

	The Plumb Bob
		In a sense, the plumb bob is the vertical equivalent of the line level.
		The plumb bob is useful in establishing vertical for a wall in construction or a doorjamb when hanging a door.
		Plumb bobs may weigh as little as an ounce or as much as several pounds, depending upon the application.

		Physical geodesy is the study of the physical properties of the gravity field of the Earth, the geopotential, with a view to their application in geodesy.
		Traditional geodetic instruments such as theodolites rely on the gravity field for orienting their vertical axis along the local plumb line or vertical with the aid of a spirit level.
		The local direction of gravity or vertical or plumb line is on every point on Earth perpendicular to the geoid.

		Level - an adjective describing a line, surface, or plane lying parallel to the plane of the horizon (axis or the earth) having the same height everywhere 5.
		Plumb - an adjective describing a line, surface, or plane that is exactly vertical or true.
		To make a plumb mark on a vertical surface, position the level against the surface so that the bubble in the tube located near the end of the level is centered, then mark a line with a sharp pencil along the edge of the level.

		The Fellowcraft learns to judge his work by his own plumb line, not by anothers; if he erects that which is good work, true work, square work by his own working tools - in other words his own standards- he does well.

		They expected that the plumb lines would converge toward the center of the earth, and by measuring how much closer the plumb lines were at the bottom than at the top, a calculation of the convergence angle could be made.
		This equation shows that the plumb line deviation from the radial line is zero at the poles, and zero at the equator, but it is a maximum at 45° and near maximum at nearby latitudes.
		So the Tamarack plumb lines were simply a standard method for establishing the correct direction to dig a horizontal tunnel, by transferring a direction line from the surface down to the bottom of the two plumb lines.

	Dave Pelz Golf - Scoring Game Tips
		The principles of a plumb-bob or plumb line are violated by the way golfers use them to read putts, which is an interesting phenomenon.
		Only when these four conditions are met will the plumb line appear to be on the upper side of the hole, indicating that the putt will break from the upper to the lower side of the hole.
		In fact, if a golfer stands exactly vertical with his eye on the ball-hole line and holds a true vertical plumb line in front of his eye so it passes over the ball, then all putts, no matter how the green slopes between the ball and the hole, will appear to be straight.

	Plumb line - Wikipedia, the free encyclopedia
		A plumb line is a reference line guided by a string or cord weighted at the end with a large weight known as a plumb bob.
		The line has in every point the same direction as that of the force of gravity of the Earth; thus, an object dropped on the surface of the Earth tends to follow this line.
		Strictly speaking the plumb line is not straight: it is curved mainly in the North-South direction (approximately 0.2" per km of elevation).

	The PuttingZone- Plumb Bobbing... On Target or Outta Line?
		What appears to be going on instead in plumb bobbing is that golfers are pointing their gaze along their IMPRESSION of the putt's start line, given a general holistic understanding of the slope, break, and total putt path implied.
		Plumb bobbing strikes people as effective because it confirms the subconscious read of slope (not break), which depends upon posture and sighting-alignment biases, and because in these cases it seems seldom to hurt the putt.
		For plumb bobbing to be useful and reasonably accurate, you have to know the slope you're standing on with some fair degree of accuracy.

		A plumb line is simply a line with a weight attached to one end, by using it you can check whether things are vertical.
		plumb lines are useful for any job when you need to know the true vertical.
		Just as a plumb line is used to check the true vertical, so a spirit level is used to make sure that things are exactly horizontal level with the horizon.

		It is indicated, in practice by a carpenter's "plumb line." Since the Earth is a sphere, however, the perpendicular to the Earth's surface at a point is co-directional with the Earth's radius at that point.
		Therefore, the vertical line (plumb line) at a point is the continuation of the Earth's radius at that point.
		Accurate measurements have shown that if the plumb lines at two different places A and B differ in direction by one degree, then the distance measured along the surface of the Earth between A and B is about 69 land miles.

	Plumb Bob and Reading Break in Putting
		Ideally, he would stand perfectly perpendicular to the surface of the green along a line that is perpendicular to the extended line between the ball and hole, as opposed to plumb.
		This moves his head and the plumbed putter shaft to the left of an imaginary plumbed line from where he is standing.
		The bottom line, dear reader, is that while one might have some fun experimenting with this technique in playing by oneself or in practice on the putting green, time expended far outweighs any benefits gained.

	Plumb Line
		A plumb bob is attracted by the force of gravity beneath the bob.
		It is possible, due to the distribution of water and land on the Earth being asymmetric, for the Earth's center of mass to be in a slightly different location than the geometric center.
		When the size of the Earth is considered, the plumb bob is always a good approximation.

		A plumb line is a light line with a weight (plumb bob) at one end that, when suspended next to a workpiece, defines a vertical line.

	Is the Center of Gravity Located at the Bottom of the C7 Plumb Line?**
		A plumb line from C7/T1 is said to correlate with the patient’s center of gravity.
		The horizontal differences between the gravity line, the C7 plumb line, and the posterior edge of the sacral plate and the centre of the bicoxofemoral axis were measured.
		Conclusions: This study has two significant findings: (i) the C7 plumb line and the gravity line in a stabilized standing position are not coexistant; (ii) the relationship between the center of T1 and the sacral endplate is a constant marker of spinal balance in individuals without symptoms of back pain or radiographic evidence of deformity.

	Plumb Bobbing is Plumb Crazy
		Plumb bobbing only "works" (in a fashion) if you aim the hanging puttershaft down your impression of the startline, so it only confirms what you already sense, and doesn't make you a better reader of the break or make your sensing of the startline any sharper.
		What appears to be going on instead in plumb bobbing is that golfers are pointing their gaze along their IMPRESSION of the putt's startline, given a general holistic understanding of the slope, break, and total putt path implied.
		Plumb bobbing strikes people as effective because it confirms the subconscious read of slope (not break), which depends upon posture and sighting-alignment biases, and because in these cases it seems seldom to hurt the putt.
