In a nutshell, this method used a plank of wood (usually wedge shaped and weighted on one end so it would float perpendicular to the water to increase drag) tied to a long thin line that had knots tied at evenly spaced intervals. The wood would be tossed into the water and the line ...
s speed was measured with a log tied to a knotted rope. The sailors threw the log overboard, and counted how many knots unwound as the ship moved forward. They used a sandglass to time it accurately. Sailors still masure a ship’s speed in knots today. One knot is just under two ...

3. Why is the term knots used? The knot was a term earlier used as a length measure on the vessel’s log lines, which were used to measure the speed of a ship on the water. This line was marked at intervals by knots tied in the rope. 4. Why do sailors use knots? The simple ...
in a fall). By doubling the runner through the cam’s sling (fig. 3, this works for wires, too) you’ll shorten the extension. Pick just the extension you need and no more. For long routes, speed of placement and re-racking is important. To move fast, add a few extra biners to...
Cars fuel efficiency are presented in mpg. With I believe the exception of Russia, the entire world uses imperial units in aviation. Boats/ships speed and distances are measured in knots and nautical miles. People in the UK and Ireland reference body weight in “stone” (14...
23 So they measured a bunch of stuff in a group of athletic young women, looking for structural problems that every therapist in the world “knows” are risk factors for various knee problems, including the tightness of iliotibial bands … and then they waited to see who got what kinds of...
When we don’t know how to reason because we don’t understand a cause, we latch onto someone who will tell us a "truth" without having to do it for ourselves. It’s much easier if someone else can untangle Gordian truth knots for us. We don't have to labor through tedious rea...
Gibson’s intensity rekindled during his first years at the helm in Arizona, but it was measured; staff and media in Arizona reported no sign of bad Gibby. Yes, he ordered a pair of old-school, retaliatory beanings during a June 2013 game at Dodger Stadium, touching off two bench-clearin...
The energy radiated from the Sun is called solar radiation, which (as measured in wavelengths from the longest to the shortest) can be simplified as including: (a) radio waves (b) microwaves (c) infrared radiation (perceived on earth as heat) (d) the visible light spectrum (e) ...
