Why he didn’t mention is that sailing, flying is determined by the opposing force. So for instance a sail boat is fighting water currents. It’s therefore measured by knots and not miles or kilometres. If you said a bit is capable of 15miles it would be inaccurate as it would depend on which way the current was flowing.
@@ryanwaugh1 I don't think it would differ much. I think they just used it always and didn't want to change that. Maybe there is another reason, but basicaly mph and knots-per-hour are both length per time, just like you can drive a car with kph or mph the same, just have to know how luch the relation between them is
@@sinandemir1867 makes a very big difference. Areas like South Africa, or along the Florida straight where currents are fast it would make a huge difference.
Knots make a lot of sense compared to mph. In the coordinate system you have degree and minutes 50°22.0' E for example. 1' minute equals one nautical mile and knots equal nautical miles per hour. So it's actually the correct speed unit when using our coordinate system on earth.
It seems made up, though. I always thought that "knots" was short for "nautical miles". Maybe I'm wrong. IDK. But one should always have a skeptical mind.
Some sailboats can do 100 km per hour too... So he's probably talking low end of cruising speeds. 6 to 13 knots is petty typical in moderate winds anyway.

Actually, the distance between the knots is such that one knot corresponds to one nautical mile per hour, with one nautical mile corresponding to the distance at sea level of one minute of latitude measured in a north-south direction (i.e. along a meridian). The nautical mile is about 1.15 statute miles or 1.85 kilometers. It is a more convenient unit of length for navigation than statute miles and kilometers. The latitude scale on a nautical chart is used to measure distance with dividers on a paper chart.
A nautical mile is 6080 feet. So for him to use a rope to measure 3 knots per hour. It would need to be at least 18,240 long guess. I think may someone along the way is confusing nautical miles with fathoms.
it's not a whole hour. it's a 28-second glass, with a knot every 8 fathoms. for every knot that spools out in 28 seconds, it's a nautical mile per hour, and a nautical mile is a 60th of 1° of latitude. if you've traveled 306 feet in 28 seconds, that 6 knots 3 fathoms, or 6 and 3/8th nautical miles per hour, or 39342.9 feet per hour. the modern, metricized standard of 6076.1 feet per mile gives a speed of about 6.5 nautical miles per hour, which is pretty close. now we use a radar system to measure speed, the Doppler speed log.
A knot is one nautical mile per hour. The nautical mile is based on one minute-of-angle of latitude and is the standard unit for boat and aircraft navigation since it's based on angular position, rather than terrain traversal.

chip log consists of a wooden board attached to a line (the log-line). The log-line has a number of knots at uniform intervals. The knots were typically spaced 47 feet, 3 inches apart.The log-line is wound on a reel so the user can easily pay it out. Over time, log construction standardized. The shape is a quarter circle, or quadrant with a radius of 5 inches (130 mm) or 6 inches (150 mm),[1] and 0.5 inches (13 mm) thick.[1] The log-line attaches to the board with a bridle of three lines that connect to the vertex and to the two ends of the quadrant's arc. To ensure the log submerges and orients correctly in the water, the bottom of the log is weighted with lead.[1] This provides more resistance in the water, and a more accurate and repeatable reading. The bridle attaches in such a way that a strong tug on the log-line makes one or two of the bridle's lines release, enabling a sailor to retrieve the log.
To answer this question with more detail, the speed captured by measuring in Knots is also relative to the fluid. The fluid can and does move in a different direction to the wind for sail boats. In short, you can go fast on the water, but slow relative to the ground if the water is moving against your desired direction. By the way, since air is mechanically considered a fluid, that is why planes use knots as a speed system.
That's not why they use knots, though. They use knots because nautical miles are a more convenient unit to divide large scale maps into. One nautical mile is one minute of latitude, so one knot is one minute of latitude per hour.
Really puts in perspective why so many people didn't make it from Europe to America when they first started sailing. They were practically walking across the entire ocean... that's a long freaking trip
Smaller ships are/were that speed, but larger ships with tons of sails could go faster. Max burst speed attained by a sailing ship was 25 mph (a lot slower than modern specialized speed sail _boats which attained 75 mph record)_, although due to the lack of wind consistency, the average speed (over days) for typical fast ships would be around 6 or 7 miles per hour. So I suppose it's not too far off.

The nautical mile per hour is one minute of latitude per hour or roughly 1.151 mph. It's just easier to navigate with. Idk how they measured speed in the past but I'm pretty sure it's called a knot to be short for nautical mile per hour. It's just a mouth full to say the full thing. I've seen this story elsewhere but I'm not really sure it's anything more than a fun tale to explain an abbreviation.
It's not too difficult. The fluid in your inner ear helps you balance, there's usually something to brace yourself against, and focusing on the stove helps too. I've never seen nor have I ever tried sitting down like he did when cooking, honestly I think that would make it harder. Standing braced against something gives you more mobility to compensate for the waves.
They used to use logs as books back in the day because sea fearers could easily scratch with a knife their records into the log, and if the ship sank the log would float and could be retrieved for vital information similar to a black box in modern aircraft. Information like knots, bearings, and pretty women were scratched into the log. Ships would keep someone in the crows nest scouting for many objects, but log books floating around from sunken vessels were always retrieved.
@@yellowawesomeness3857 a knot (measurement of distance) is equal to a nautical mile, which is specifically used in marine industries, and is longer than the standard mile used on roads or general common usage. Knots are often used to denote speed in water, similar to miles per hour. If I’m going 60 miles per hour on land, I would not be moving at 60 nautical miles per hour.

@@SuperAd1980 then whats the right one mr smarty pants? Because from what i see is this The term knot dates from the 17th Century, when sailors measured the speed of their ship by the use of a device called a “common log.” This device was a coil of rope with uniformly spaced knots tied in it, attached to a piece of wood shaped like a slice of pie. Source: (oceanservice.noaa .gov) And also this Ancient mariners used to gauge how fast their ship was moving by throwing a piece of wood or other floatable object over the vessel’s bow then counting the amount of time that elapsed before its stern passed the object. This method was known as a Dutchman’s log. By the late 16th century, sailors had begun using a chip log to measure speed. In this method, knots were tied at uniform intervals in a length of rope and then one end of the rope, with a pie-slice-shape piece of wood (or “chip”) attached to it, was tossed behind the ship. As the vessel moved forward, the line of rope was allowed to roll out freely for a specific amount of time, which was typically tabulated with an hourglass. Afterward, the number of knots that had gone over the ship’s stern was counted and used in calculating the vessel’s speed. A knot came to mean one nautical mile per hour. Therefore, a ship traveling at 15 knots could go 15 nautical miles per hour. (Source:History.com)
When I lived in S Florida, I spent countless hours over 10 years aboard my buddies 60ft motorsailer. We rarely went under sail , because the boat had a Detroit , 2-stroke , 671 diesel engine. It only consumed 2 -2.5 gallons per hour ( gph )and we cruised between 9-12 knots . Diesel was so cheap for so many years , now it’s very expensive , and the boating industry is taking a big hit I’m guessing . The Detroit 471 is even more economical .
Knot is short for nautical miles per hour. One nautical mile is equal to the arc length of one minute of angle at sea level. So it actually makes a lot more sense than imperial miles. If you're in a boat, traveling at five knots, it's fairly easy to calculate how far you'll travel in, for example, eight hours.
Next time I get pulled over for speeding and the cop tells me I was going 70 on a 55, I’ll tell him sorry chump, I was going 55 knots by my boat’s speedometer.
Factually correct, I heard the same knot story from my wise navigation department chief. Gotta love sailing history, so many time honored traditions honored to this day
@Logan Easley how did they measure nautical miles back then without a mechanism to take those measurements. Line and floating timber are common aboard wooden vessels so I couldn't see why it can't be true
@@loganeasley4343 This is true, when I was a child in the 1960s, I used to see this happening on ferries going out into Liverpool Bay where crew members would do this at the stern. My father who had served in the Navy explained it to me.
Years ago my son had a Make-A-Wish. His wish was to do a Disney Cruise. Each night we were out to sea, they would shut off all the lights on the ship for a length of time. I have never since seen so much starlight in the sky as I did on that cruise. Even in the highlands of Guatemala in a small village in Pastores, the night sky wasn’t so full of light as it was those nights. I recall feeling so insignificant that I knelt down; so awestruck, I had to remind myself to breathe. I forgot I was on a cruise. I forgot my wife was standing next to me. If doing a cruise is not in the cards for you, check out a Dark Sky map for dark sky areas near you and go there, even for a little while. It’s pretty cool!
Knots because it’s about being relative to the body of water your sitting on. You could be going against a tidal current for example so relative to the land your not moving at all but your engine is running you at 5 knots because the current is 5 knots. Water is always moving so it’s better to use a different metric. You can always convert knots to any other Si unit with simple calculations anyway. Same applies for aircraft knots/feet normally used.
I feel like this explanation misses the point. With a slightly different length between the knots in the rope they could have used regular miles per hour. The real reason why they use knots (nautical miles per hour) is that it makes transit times over large scale maps divided into degrees of latitude/longitude easy to calculate. There are per definition 60 nautical miles between lines of latitude. One knot is one minute of latitude per hour. Speed through the water/speed over ground is completely orthogonal to the choice of unit.
I thought it was a taffrail log that would be sent off the stern to record the boat speed through the water in nautical miles (1 minute of latitude) per hour, aka knots.

@@a-a-rondavis9438 because there were no effective means of recording large amounts of data, so any measurements had to be relative to another tangible thing, like feet being the length of the king’s foot, or an acre the area of land that could be plowed in one day by a yoke of oxen pulling a wooden plow

Oh my god now I understand. Knots are actually slower. This is amazing. This is amazing. again this is amazing. I would’ve loved to be a part of the group that figured out how to measure your speed this way cause that would’ve been pretty cool.
A vessel’s shaking affects you the first… 10-30 minutes. It’s like being on a plane. It’s annoying at first, but then your body remembers we’ve been doing it for the last 10,000 years.
But over a couple thousand miles of distance, you may indeed average a speed of 3 knots, especially if you are traversing the equator. The doldrums are a thing, and can slow you down significantly.
Another good thing about Knots and Nautical Miles is that they correspond to coordinates very neatly. 1° of the 360° circumference of the earth would be 60NM. And degrees are counted like minutes, so 1°01' would be exactly 61NM (On a great circle).
Tow boats on the inter coastal and Mississippi also use mph. We use Knots or Nautical Miles per Hour because it’s easier for navigation as well. 1 nautical mile is equal to 1’ (minute) of latitude. I could figure out initial course and overall distance of a route by mathematical equation if you give me the latitude and longitude of the starting and finishing location.
Sorry. Nautical miles are taken from the vertical edge of a Mercator map. There are many abbreviations in nautical terms. Starboard goes back to double ended Viking boats. The steering oar was over the right hand side of the stern post. The steering board.
Yes I feel you might want to keep going in your research. The specific distance "the knot in the rope" lets them calculate how many knots you're making. It would be hard to have a mile of rope. Your car doesn't have to travel a mile to indicate how many miles per hour you're try to travel. Remember current also affects this. 4 knots of speed in a current against you may push you into negative forward progress. It is amazing how well they could navigate without real accurate information. Kind Regards good man!
Officer: Do you know how fast you were going? Me: I'm only 20 minutes into checking my speed, captain. I'll check me log book and get back to ye after lunch.
Ultimately I believe the reason we STILL use knots is because it isn't based on Speed over Distance traveled directly... It's based on Speed over Current travelled... My understanding is that if the tides are pushing you backwards, but you are still moving forwards, knots measures the difference between the 2, where MPH wouldn't
No, that's wrong. Knots can indicate either speed over ground or speed through water, just like mph. The reason we use knots is that when we made maps we divided the earth into degrees of latitude and longitude. We defined a "nautical mile" to be 1/60 of a degree of latitude. That's why we use knots, it's nautical miles per hour and it's based on how we've designed our maps and the size of the earth. It just makes it easier to reason about long distances on big maps of a spherical planet.
Well, it's not too far off. Since you have nautical miles, in which the distance of the knots tied allowed for the measurement of nautical miles per hour.
Aviation uses knots in airspeed and groundspeed. A nautical mile (or sometimes called a knot) is 6,000 feet. A statute mile is 5,280 ft. Pilots also use logbooks.
I never knew why either until one day it occurred to me that it’s because the water is moving. If the water is moving in a direction, and then you’re sailing in that same direction, you will have whatever speed your sail or engine is producing in addition to the speed caused by the moving water. A nautical mile is the same as a land mile, it’s just measured on water. If the water is moving 10mph, and you’re ship is sailing 10 nautical miles per hour; then you would be moving 10 knots and 20mph. If the water was moving 5mph in the other direction, you would still be moving 10 knots but only 5mph.
I sailed from Wisconsin to Florida with my kids and my wife. It took 8 months. Slow going... but beautiful. In the Erie canal, the kids walked along the path as i sailed down.
This video is a partial answer. Nautical miles until given a recent finite quantitative redefinition, were defined as the distance representing one minute of arc around the Equator. That used to mean more that statute miles in the days of navigation via sextants and compasses, both trig based systems.

Really puts in perspective why so many people didn't make it from Europe to America when they first started sailing. They were practically walking across the entire ocean... that's a long freaking trip
Smaller ships are/were that speed, but larger ships with tons of sails could go faster. Max burst speed attained by a sailing ship was 25 mph (a lot slower than modern specialized speed sail _boats which attained 75 mph record)_, although due to the lack of wind consistency, the average speed (over days) for typical fast ships would be around 6 or 7 miles per hour. So I suppose it's not too far off.

Knot = Nautical Miles (NM) per hour
NM = 1 minute of latitude (1.853 kilometres approx.)
This isn't entirely true, but it is close.
Not Ture lmao
@@C.V._McCullar 1.852 km. Pretty close and his 1 minute of latitude is straight on. I would not worry too much about that 1 meter when using my sextant in the middle of the ocean on an oversailer.

@@Daveeeeeeyhowyoudoing What is a Ture?
Was looking for this comment.
The nautical mile per hour is one minute of latitude per hour or roughly 1.151 mph. It's just easier to navigate with. Idk how they measured speed in the past but I'm pretty sure it's called a knot to be short for nautical mile per hour. It's just a mouth full to say the full thing. I've seen this story elsewhere but I'm not really sure it's anything more than a fun tale to explain an abbreviation.
This is the correct answer
Modern sailboats used for racing - fastest speed was 65 knots! Even weirder, they move 2 to 3x the speed of the wind to do that.
You can also do the same with windsurfing boards. The Sail is shaped like an airplane wing and creates additional "lift"
trying to cook in that boat is lookin hectic
Bro I almost stopped breathing cause of this 🤣🤣🤣
notice that the stove stabilizes.
It's not too difficult. The fluid in your inner ear helps you balance, there's usually something to brace yourself against, and focusing on the stove helps too. I've never seen nor have I ever tried sitting down like he did when cooking, honestly I think that would make it harder. Standing braced against something gives you more mobility to compensate for the waves.
I lived aboard and cruised for 18 years on a cal 2 46 what a wonderful boat
They used to use logs as books back in the day because sea fearers could easily scratch with a knife their records into the log, and if the ship sank the log would float and could be retrieved for vital information similar to a black box in modern aircraft. Information like knots, bearings, and pretty women were scratched into the log. Ships would keep someone in the crows nest scouting for many objects, but log books floating around from sunken vessels were always retrieved.
A knot is a nautical mile which is longer that a statute mile.
What does that even mean?
@@yellowawesomeness3857 a knot (measurement of distance) is equal to a nautical mile, which is specifically used in marine industries, and is longer than the standard mile used on roads or general common usage. Knots are often used to denote speed in water, similar to miles per hour. If I’m going 60 miles per hour on land, I would not be moving at 60 nautical miles per hour.
Correct me if I'm wrong here but a believe a Nautical mile is a measurement of both distance and speed while a "knot" is only a measure of speed
1 knot = 1.2mph

The term knot dates from the 17th Century, when sailors measured the speed of their ship by the use of a device called a “common log.” This device was a coil of rope with uniformly spaced knots tied in it, attached to a piece of wood shaped like a slice of pie. Source: (oceanservice.noaa .gov)
And also this
Ancient mariners used to gauge how fast their ship was moving by throwing a piece of wood or other floatable object over the vessel’s bow then counting the amount of time that elapsed before its stern passed the object. This method was known as a Dutchman’s log. By the late 16th century, sailors had begun using a chip log to measure speed. In this method, knots were tied at uniform intervals in a length of rope and then one end of the rope, with a pie-slice-shape piece of wood (or “chip”) attached to it, was tossed behind the ship. As the vessel moved forward, the line of rope was allowed to roll out freely for a specific amount of time, which was typically tabulated with an hourglass. Afterward, the number of knots that had gone over the ship’s stern was counted and used in calculating the vessel’s speed. A knot came to mean one nautical mile per hour. Therefore, a ship traveling at 15 knots could go 15 nautical miles per hour. (Source:History.com)
Wow. New knowledge is always helpful!
I’ve always wondered about the knots thing. Crazy age of sail lol
When I lived in S Florida, I spent countless hours over 10 years aboard my buddies 60ft motorsailer. We rarely went under sail , because the boat had a Detroit , 2-stroke , 671 diesel engine. It only consumed 2 -2.5 gallons per hour ( gph )and we cruised between 9-12 knots .
Diesel was so cheap for so many years , now it’s very expensive , and the boating industry is taking a big hit I’m guessing .
The Detroit 471 is even more economical .
I mean, what’s the tank size on some thing like that? Is it like 120 gallons?
Captains log, LMAO I never once stopped asking why they kept saying that in Startrek, or anywhere else for that matter. Very insightful video.
Knot is short for nautical miles per hour. One nautical mile is equal to the arc length of one minute of angle at sea level. So it actually makes a lot more sense than imperial miles. If you're in a boat, traveling at five knots, it's fairly easy to calculate how far you'll travel in, for example, eight hours.
Next time I get pulled over for speeding and the cop tells me I was going 70 on a 55, I’ll tell him sorry chump, I was going 55 knots by my boat’s speedometer.
Factually correct, I heard the same knot story from my wise navigation department chief. Gotta love sailing history, so many time honored traditions honored to this day
Dawg is this some sort of sailing in-joke? This story seems like total bullshit lmao. I swear knots is just short for nautical miles per hour.
@Logan Easley how did they measure nautical miles back then without a mechanism to take those measurements. Line and floating timber are common aboard wooden vessels so I couldn't see why it can't be true
@@loganeasley4343 This is true, when I was a child in the 1960s, I used to see this happening on ferries going out into Liverpool Bay where crew members would do this at the stern. My father who had served in the Navy explained it to me.

Years ago my son had a Make-A-Wish. His wish was to do a Disney Cruise. Each night we were out to sea, they would shut off all the lights on the ship for a length of time. I have never since seen so much starlight in the sky as I did on that cruise. Even in the highlands of Guatemala in a small village in Pastores, the night sky wasn’t so full of light as it was those nights. I recall feeling so insignificant that I knelt down; so awestruck, I had to remind myself to breathe. I forgot I was on a cruise. I forgot my wife was standing next to me.
If doing a cruise is not in the cards for you, check out a Dark Sky map for dark sky areas near you and go there, even for a little while. It’s pretty cool!
Knots because it’s about being relative to the body of water your sitting on. You could be going against a tidal current for example so relative to the land your not moving at all but your engine is running you at 5 knots because the current is 5 knots. Water is always moving so it’s better to use a different metric. You can always convert knots to any other Si unit with simple calculations anyway. Same applies for aircraft knots/feet normally used.
I feel like this explanation misses the point. With a slightly different length between the knots in the rope they could have used regular miles per hour.
The real reason why they use knots (nautical miles per hour) is that it makes transit times over large scale maps divided into degrees of latitude/longitude easy to calculate. There are per definition 60 nautical miles between lines of latitude. One knot is one minute of latitude per hour. Speed through the water/speed over ground is completely orthogonal to the choice of unit.
The explanation on why they use knots instead of mph just blew my mind. Thank you !!!
I thought it was a taffrail log that would be sent off the stern to record the boat speed through the water in nautical miles (1 minute of latitude) per hour, aka knots.
This is 100% correct
Why, he would explain how knots were named without explaining what the term meant is a bit of a mystery.
That’s it. I’m tossing a log out the window and judging my speed in knots from now on.

But the way they determined knots sounds so primitive and quite frankly stupid. Who even comes up with that?
@@a-a-rondavis9438 because there were no effective means of recording large amounts of data, so any measurements had to be relative to another tangible thing, like feet being the length of the king’s foot, or an acre the area of land that could be plowed in one day by a yoke of oxen pulling a wooden plow
And the Log book being used to keep track of data obtained via. . . a Log 🤣

Oh my god now I understand. Knots are actually slower. This is amazing. This is amazing. again this is amazing. I would’ve loved to be a part of the group that figured out how to measure your speed this way cause that would’ve been pretty cool.
Technically faster, since traveling at 1 knot is faster than 1 mile per hour

I was a whole Navy Sailor for 9 years and never learned that 😂
At some point did you become less than a whole navy sailor?
You were def a top or bottom half of a sailor.
Well you guys use propellers not sails
U def were not paying attention, and should not call itself a sailor.
For anyone wondering what the actual difference is:
1kt = 1 nautical mile per hour (NM/h)
1NM = 6080 ft
1 mile = 5280 ft
Sailboats can move fast, many have engines as well as sails and if there's a fairly good breeze you'll be going much faster than 3 knots
But over a couple thousand miles of distance, you may indeed average a speed of 3 knots, especially if you are traversing the equator. The doldrums are a thing, and can slow you down significantly.
Another good thing about Knots and Nautical Miles is that they correspond to coordinates very neatly. 1° of the 360° circumference of the earth would be 60NM. And degrees are counted like minutes, so 1°01' would be exactly 61NM (On a great circle).
Oh that's fire..... I watch james but it's been a while
Fun fact: Sailing in the Great Lakes does not use knots, they use MPH.
Tow boats on the inter coastal and Mississippi also use mph. We use Knots or Nautical Miles per Hour because it’s easier for navigation as well. 1 nautical mile is equal to 1’ (minute) of latitude. I could figure out initial course and overall distance of a route by mathematical equation if you give me the latitude and longitude of the starting and finishing location.
Y only the great lakes using mph not knots?? When everywhere else uses knots for speed on water
Maybe on your boat, but I've only encountered people talking in terms of nautical miles growing up/sailing in Michigan
@@brycek3434 on the ships on the Great Lakes, we use mph.
@@brycek3434 A pleasure craft/boat? More like a 1,000ft ship. We use mph not knots.
Sorry. Nautical miles are taken from the vertical edge of a Mercator map. There are many abbreviations in nautical terms. Starboard goes back to double ended Viking boats. The steering oar was over the right hand side of the stern post. The steering board.
Yes I feel you might want to keep going in your research. The specific distance "the knot in the rope" lets them calculate how many knots you're making. It would be hard to have a mile of rope. Your car doesn't have to travel a mile to indicate how many miles per hour you're try to travel. Remember current also affects this. 4 knots of speed in a current against you may push you into negative forward progress. It is amazing how well they could navigate without real accurate information. Kind Regards good man!

It is always good to learn something new everyday.
Ultimately I believe the reason we STILL use knots is because it isn't based on Speed over Distance traveled directly... It's based on Speed over Current travelled... My understanding is that if the tides are pushing you backwards, but you are still moving forwards, knots measures the difference between the 2, where MPH wouldn't
No, that's wrong. Knots can indicate either speed over ground or speed through water, just like mph.
The reason we use knots is that when we made maps we divided the earth into degrees of latitude and longitude. We defined a "nautical mile" to be 1/60 of a degree of latitude. That's why we use knots, it's nautical miles per hour and it's based on how we've designed our maps and the size of the earth. It just makes it easier to reason about long distances on big maps of a spherical planet.
Meanwhile, all competent sailors and shipwrights

Aviation uses knots in airspeed and groundspeed. A nautical mile (or sometimes called a knot) is 6,000 feet. A statute mile is 5,280 ft. Pilots also use logbooks.
Thank you I’ve always wanted to know that 🙏🏿🙏🏿🙏🏿👍🏿👍🏿👍🏿👍🏿💯. Never thought 💭 to look it up. Thx
I never knew why either until one day it occurred to me that it’s because the water is moving.
If the water is moving in a direction, and then you’re sailing in that same direction, you will have whatever speed your sail or engine is producing in addition to the speed caused by the moving water.
A nautical mile is the same as a land mile, it’s just measured on water.
If the water is moving 10mph, and you’re ship is sailing 10 nautical miles per hour; then you would be moving 10 knots and 20mph.
If the water was moving 5mph in the other direction, you would still be moving 10 knots but only 5mph.
I thought about that question a few days ago and now I get the explanation randomly .

This video is a partial answer. Nautical miles until given a recent finite quantitative redefinition, were defined as the distance representing one minute of arc around the Equator. That used to mean more that statute miles in the days of navigation via sextants and compasses, both trig based systems.
