I agree with "Pixer AB". My Dad use to say you can tell if someone REALLY understands what they are talking about if they can explain it in terms/pictures that are easy to understand by anyone and anyone can get it. Well done here!!
Ken, this was a great presentation that put some great content into my noggin. One small bit of constructive criticism. Axis (singular) is pronounced axus... while axes (plural) is pronounced axEEz. I really hope to learn a lot from your content. You're a great teacher.
@@gabrielpalacio6710 No The arcminute is 1.15 statute miles at the equator, the meridians reducing distance apart as we move north or south. Remember the Cosign part ?
From Wikipedia: A prime meridian, based at the Royal Observatory, Greenwich, in London was established by Sir George Airy in 1851. By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, at the behest of U.S. President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., USA, for the International Meridian Conference. This conference selected the meridian passing through Greenwich as the official prime meridian due to its popularity. However, France abstained from the vote and French maps continued to use the Paris meridian for several decades.
First of all I'd like to thank you for upIoading this video. I don't know much about geography and for this simple reason I find this video immeasurably helpful. But there is one thing I would be really thankful if you helped me with. When I tried to convert the figures into kilometers, which is more clear for me because kilometers are used to measure distances where I live, I faced a strange thing - 1 statutary mile = 1 nautical mile = 1.853 km. The information I found told me that there is some old metric system that says 1 mile = 1.609 km (((((((((((
Dear Prof. Yanow, Going back to your video and stop it at 8.34, I would like to know how we can possibly prove that the two angles you have drawn on that circle are congruent? Thank you
But doesn't the earth also tilt on it's axis (summer to winter) which means the true north pole also tilts? Does Polaris follow this tilt? Very good lesson by the way.
The Earth itself is not changing its tilt orientation during the seasons. The north geographic pole is always pointing toward Polaris. So, as the Earth revolves around the Sun, the Earth is tilted 23.5 degrees relative to the plane of the ecliptic (that is, relatively to the position of the Sun). During the summer solstice (June 21), the northern hemisphere is pointed toward the Sun. A half a year later (Winter Solstice, Dec 21), the Earth's tilt is in the same orientation, which means the northern hemisphere is now pointed away from the Sun (Winter Solstice, Dec 21). See the image on this page: courses.lumenlearning.com/astronomy/chapter/the-seasons/
I've alway's wondered as to why when the line referred to as the equator is "LONGER" than the line circleing North to South. Is it not the "LONG ITUDE", While the shorter one going North and South is.
There are a lot of stars out there! Having a North Star is nothing amazing. Also, the Earth wobbles (it’s about a 20,000 year precession cycle). So, Polaris is not always the North Star.
Both the American and British Stautory Mile are equal and are 1.760 yards. or 5,280 feet. The standard was agreed 1959 with the British Commonwealth nations and the United States. Chinese miles differ a great deal in length( approx 500 metres) . The origins of the Statute mile (read Statutory mile) are based on the Roman method of measuring paces made by the Soldiers as they made 'feet' steps. 1,000 paces being roughly equal to a mile. Hope this clarifies things.
Dear Professor, please reconsider your explantion (elaborate!) after your question at 3 minutes about the same points of Latitude ("..what about here, and here and here..." - not at all "OBVIOUS"!). You never explained how other points on the same line of Latitude can be derived (by means of using the line-length of the angle drawn away from the center and then reconstructed as a parallel with the a point at the end of the line at that angle anywhere on the equator). Sorry, to be so direct, but I found this section of your video to be a poor (incomlete) explanation. The rest is very good and well explained. Perhaps you would want to make a revised video or add this section, explaining this in more detail - thanks for your otherwise excellent video.
+Michael Berkemer I agree, I was also stuck there and it took me quite long to understand (I hope I did now). So the angle is calculated from "inside" the globe, I was thinking about in on the circular surface first ... very confusing, I am not sure how to say it.
If you haven't found your answer yet, I would like to help you. Are you interested? The answer to your last question is "no" you won't be able to see Polaris during the daytime.
Maybe it would be better to have a shorter video than a half hour video learning about 2 different things. I'm giving this a dislike because the writing just seems messed up and could u please say "longtitude" correctly? Thanks
Fantastic! and, thanks a lot, Prof. But could you brush up on your English, please? Longitude is not pronounced "logtitude". Neither should "nuclear" be pronounced "nukuler". America and Britain......two great nations divided by a common language !! Geoff Tyson
And Gas is Petrol. What about oxygen being a gas ? lol Come on guys, a little knowlege of our distant cousins please. The object of the video is to teach us how to navigate the world not instruct us in the art of language. Give the guy some credit for a job well done.
Every pilot, student or not, needs to listen to this lecture! Fantastic!

Easy to understand, which would equal well explained!
Best 30 minutes I've spent in a long time.
Easily one of the best explanations I've come across, Thank You Very Much.

I've learnt more watching this than my teacher teaching it omg
because it's a second or third pass on the info for you
1.15 / 60 is 0.02 so each arc minute gives you a 2 one-hundredth part of a statute mile.
Yeah, that's what I was noticing.

I have a geography test tomorrow and you just really saved me!! I AM SO GRATEFUL!!! >.
IT IS FAKE VIEDO
great man. dont be afraid to use a crutch like round circles and lines. keep em coming.

Hello, Sergey.
1 statutory mile = 1.609 km
1 nautical mile = 1.15 statutory miles = 1.853 km.
Dear Prof. Yanow,
Going back to your video and stop it at 8.34, I would like to know how we can possibly prove that the two angles you have drawn on that circle are congruent? Thank you
You know how the French are.
French arrogance is still going strong to this day. The Brits are no slackards in this regard. Who are the humble people ? The Americans ?
Watching it from San Diego, California. Thanks for teaching
same here!
Excellent explanation. Im brazilian and I can unsderstand very well. Thank you.
i have respect for acncient sailors they ain't got gps to supply them answers and figured all on their own.
Someday, I'm going to tell my friends our long/lat without using my phone. I am going to learn this somehow.

Best explanation. Thanks.
this video is simply awesome
Very good explanation! Good job
I hope your art improves when you get to middle school.
So Polaris lines up exactly with earths axis is this by accident or is there intelligent design
Er, regarding the second part of your question......you said this for comedic effect, yes?
Very well explained. Thank you so much.
Thnx brother for such a nice lecture.
such a good video!
Oh come on guys! He tried his best teaching :/
You guys are very mean he did do his best!
Awesome lecture ! Thank you.
wonderful lesson bro.
great video 10nx
You are a good teacher
Is a statutory mile defined by act of a legislative body?
Both the American and British Stautory Mile are equal and are 1.760 yards. or 5,280 feet. The standard was agreed 1959 with the British Commonwealth nations and the United States. Chinese miles differ a great deal in length( approx 500 metres) .

Hope this clarifies things.
Superbly taught !!!!
Please give me tutions
"Statute" not statutory.
Very good presentation
? what about true North, ?
Thanks u made my day
GOOD
Flat earthers are sat whining in a corner. "Say it ain't so mister".
But it is.

So equip with sense
amazing video sir
i didnt understand the polaris part and that knuckle or fist part
and polaris seem to be on top of the axis
do it appear at day time too ?
If you haven't found your answer yet, I would like to help you. Are you interested? The answer to your last question is "no" you won't be able to see Polaris during the daytime.
lolo
Maybe it would be better to have a shorter video than a half hour video learning about 2 different things. I'm giving this a dislike because the writing just seems messed up and could u please say "longtitude" correctly? Thanks
Funny Life he did say longitude correctly!
agree
Why u taking kids out in the middle of the night😆
Keeping them out of gangs and giving them something intelligent to do. He's not a Catholic priest. Probably ok. lol.
Very good.
My children are not understand
thank you
Earth rotation
thx man that help alot its my lesson
Thanks
thanks bro i learn my lessons
thanks for teaching me
Thank you, your video good for me. I'm a sunday sailor.
awesome.
nice videos
thank you sir
1 MISTAKE STARS MOVE NOT THE EARTH.thats why santa missed my house last year............rich..................acoG
thx
Hmmm verry nice
Globbledygook
could you please remake the video, applied on the true flat Earth and not on the ball Earth that only exists in the heads of people? Thank you.
Fantastic! and, thanks a lot, Prof.
But could you brush up on your English, please?
Longitude is not pronounced "logtitude".
Neither should "nuclear" be pronounced "nukuler".
America and Britain......two great nations divided by a common language !!

crapy diagram
F-up mess.
HE DON'T KNOW TO MAKE A CIRCLE
The Earth is flat though!
I HATE IT
Santosh Kumar I HATE YOU
EARTH is flat
rene ibarlucea 😂😂😂
Thank you
thanks
thank you sir
