I just wanted to come back here and tell that yesterday evening I saw the moon and remembered this video. It was beautiful full moon and all. I started to think how it worked and then I started to deduce that when it's full moon it has to be at the opposite direction to the sun, so it rose 12 hours later than the sun did. It looked like it was about 3 hours after it rose, so I calculated that it had to have been like 9 pm. And then I realized it should be pretty close given I was walking out in the evening. Looked at my phone, and it was 10 minutes off. :D I think that was pretty cool.
I learned how to do this a while ago too, but not intentionally, I was more just interested in understanding the moon's behavior. But once you can really visualize what is happening in the sky it almost becomes second nature to read the moon like the sun. This is how I approached it: First I made some observations: -The sun and moon both [appear to] go in circles around the earth (obviously), rising in the east and setting in the west, however the sun 'moves' a little faster than the moon, so it's always catching up and passing the moon, like cars on a race track. You can literally watch this when the sun and moon are close. If the moon rises first you can watch the sun get closer to it throughout the day. -If the illuminated portion of the moon was it's face it would always be looking at the sun. If it is looking ahead (in the direction of travel) then the sun must be ahead of it, so it is lagging behind. -The moon is full when it is opposite to the sun, so if the moon is lagging it is getting farther behind which means it is waxing, or getting closer to full. Understanding those concepts means you can easily tell whether the moon is leading or lagging relative to the sun. Based on this you can make associations with the phases of the moon: •No moon: sun and moon are in phase -New Moon •Crescent moon looking forwards (sun rises first): the moon is lagging (⅛th, 45°, 3h) behind the sun. Because the sun is moving faster and is already ahead that means the sun and moon are getting farther apart, so the moon is going towards full (waxing), so this is a first crescent. •Half moon, lagging: Moon is ¼/90°/6h behind the sun, waxing. First quarter. •¾ moon, lagging: Moon is ⅜/135°/9h behind the sun, waxing. Waxing Gibbous. •Full moon: the sun and moon are at opposite ends of the 'race track', the farthest apart possible, at opposition. The sun and moon are half a day/180°/12h apart. After this point the sun and moon start getting closer again and it's like the moon is leading the sun. •¾ moon, leading: the moon is looking backwards now at the sun that is behind it, the sun is now catching up, but the moon is still ⅜/135°/9h ahead. Waning Gibbous •Half moon, leading: the moon is ¼/90°/6h ahead and losing ground. Last quarter. •Crescent, leading: the moon is ⅛/45°/3h ahead of the sun So in the first picture the moon is looking forwards and it is ¾ full, so you know it is lagging behind the sun by ⅜ of a day or 9h. This means that the sun was where the moon is 9h ago. If the sun was there it would be noon, if noon was 9h ago it must be 9pm. It's also useful for knowing when and where the moon should be for a given phase. For example, if you wanted to see the waning crescent moon you would know that it has to be fairly close to the sun, because it's waning it's looking back at the sun which means it's leading. That means it will rise about 3h before the sun. This also means it will be in the sky all day, but because it's so close to the sun you probably won't be able to see it very long after sunrise. In the evening it will set about 3 hours before the sun so you still won't see it and won't see it all night.
Random Guy I felt it was practical in terms of learning the distance and movements of the moon based on where you live and I thought the turn into trying to tell the time based on the moon instead of the sun was really interesting, I'm sorry it sounded like sarcasm. Thank you 😊
A couple of nights ago, I was out feeding the local stray cats, and looking at the moon (& Saturn) doing the mental maths to conclude the moon moves across the sky E->W its own width every 2 minutes, and its own width W
@@kieubasiarz , yep, you're right, it was. That's disappointing, it's only half as far away and easily visible often. I was hoping I was looking at Saturn that I don't often consciously notice. And it looked a lot redder than usual. Maybe because it was closer it looked more than just a bright white dot. Oh well.
That painting of Jupiter at 4:18 is super cool! I noticed a telescope in the background too! I've got a 60mm refractor and I love looking at Jupiter and seeing how the Galilean moons have changed position each night. The first time I looked at Saturn the rings made it look like an eye was staring back at me through my telescope! Keep up the good work Kurtis! Astronomy is awesome!
Thanks! I painted it myself :) Earth's got a lot of nice stuff too, but Jupiter might be the prettiest thing in our solar system. Can you imagine being the first to see Saturns weird little rings and trying to figure out why there was an eye staring back at you?
This shouldn't be my takeaway from the video, but the attention to detail of lining the timestamp arrow up (when not in cinema mode on desktop) is amazing!
That's very cool. I will watch again and take notes. Btw keep an eye on your irrigation system because the youtube recomendations algorithm is unreliable, it may flood your plants or dry them up.
"A day is the amount of time it takes for the earth to rotate once" This is a common misconception, because while,the earth is rotating, it is also moving a bit around the sun. That means after one rotation the earth is at a different position therefore from earths point of view the sun would not be in the same spot in the sky. A day is actually a bit longer so that the additional rotation of the earth compensates for that
I just wanna say ur a really under appreciated youtuber and that you need a lot more recognition than you receive. Like I gotta say ur videos give me motivation. I’m currently taking AP physics and I’m dying. But whenever I see your videos pop up in your feed it gives me a smile. I do have a suggestion. Could you make a science fair project about whether it’s more hygienic to urinate either sitting or standing asking to end a debate with a friend
I thought the Earth was flat. If it's round it's so much easier to understand. And seeing the Globe standing on a foot, I can see why we don't fall in space. Thanks Kurtis. Now let me watch the video
Great work telling the time from the Moon! As an alternative method, that is more intuitive to me, you can visualise where this phase should be on the sky when the Sun sets (or rises). Then all that's left is estimating the temporal distance between the current location of the Moon and it's location at the previous sunset (or the next sunrise)
As a non native speaker i think is not logical to refer midnight as 12 am rather than 12 pm. I mean 11:59 pm, 12:00 pm / 0:00 am, 00:01 am makes much more sense.
I'm a native speaker and I agree that it's confusing. It doesn't matter to most native speakers because people just say "midnight" and dodge the issue.
Yes, that doesn't make any sense. Why would the numbers flip back to start at the beginning at a different time than the pm/am sign? It changes from pm to am an hour before the numbers changes from 12 to 1.
In addition changing your latitude changes the orientation of the moon. In the Southern Hemisphere the moon appears upsidedown compared to the Northern hemisphere. Closer to the equator the quarter moon mostly appears horizontal instead of more vertical.
Great vid! this started me thinking... if you can tell longitude by knowing the time, say at greenwich for example, you should be able to tell the time by the stars, if you know what longitude you're at. next vid maybe?
I think it might be easier if you use the Moon's position and phase to guess where the sun is, and convert that into the time. I got all the same answers that you did in the video but a few seconds earlier.
Thank you for this video. I can't wait to understand the lunar motions and phases and I will probably return to this. Also, the transition to your sponsor was perfect.
0:02 "The next station is Commercial-Broadway" 😂 . BTW i see no other people in the skytrain. How is this possible on such a busy route? and yes, amazing work Kurtis, keep making such good videos. we support you.
During my military service we were give small notebook that a basic information(mainly focused on our patallion and its tasks) one part was about orientation and ofcause based on both sun and moon(also some info about determining time)
Commuting to work into the moonset today, my wife asked why we can sometimes see the moon during the day. So, I talked about this video. It also occurred to me it might be possible to work out approximate longitude from the moon given enough information.
There's a simpler method. If you can tell time by the position of the sun up in the sky, then you can tell time by the angle of sunlight shining on the moon. The lit half of the moon always points toward the sun, even when the sun is hidden below the horizon. By looking at the moon, you can point your arm toward the sun, through the earth. Nothing to sort out or memorize.
Interesting... I knew how to use the lit half to find the direction towards the Sun. But you also use the phase to tell the angle between them. Clever!
Thank you for this explanatory video. Daylight Saving Time needlessly obscures this basic knowledge of telling time from the sun, moon, and stars; DST distances us from nature. Please join the movement to #SaveStandardTime and to restore #PermanentStandardTime. It's the quickest way to end clock changes in America, and it's the healthiest way in all the world. Thanks again!
Loved watching you test yourself and struggling with it, made me feel better about my own stupid brain. Anyway, really interesting - I'm going to try this tonight! PS. Sorry I've only just got round to watching! :)
dunno about english but china and japan do use Moon....hieroglyph for the word month. Also in russian its "Месяц" (Mesyats) which does mean crescent moon !
I would like to tell you something. You can look at the moon, and instant guess what time is it without all the fuss. Just look and the illumination on the moon, and estimate where the Sun is below the horizon. And depending on where you estimate the Sun to be, you can guess what hour of the night it is. The images you examine here to do the guess work do not incorporate the orientation of the illumination, and that is key factor if you want to guess the time from the moon. You can do it almost instantaneously. You don't need to look at where the moons position is in the Sky. Just estimate where the Sun is from how it illuminates the white rock. Also, Ignore my account name. I can't think of a better name.
I usually do this by estimating the sun's position from the angle earth - moon - sun. Since the bright half of the moon always points to the sun, all you need is some spacial imagination, no numbers involved.
I always assumed that the moon rising "in the evening" and sets "in the morning". Of course this doesn't make sense, but really I never have given it much thought. So thank you for the clarification!
Fun fact, the word "month" in Finnish is "kuukausi" which means "moon phase" (kuu=moon kausi=phase). Mind = blown :) Finnish has a lot of similar words which are made up of the meaning. Computer in Finnish is "knowledge machine" (tieto + kone)
Hey Kurtis I was assigned to write a letter suggesting sustainable changes we can make to my high school, any ideas? I am already suggesting that we install some solar panels and buy recycled supplies for students instead of your generic stationary. Thanks!
Kurtis, I live in Vancouver as well, can you explain to me why I can see the moon all day and all night, every single day please? This being the case some areas of the world will never see the moon. Thanks
In Vancouver you are sometimes able to see the moon for up to 16hrs a day. Since that duration changes And since it shifts to different start and stop points throughout the month, it may *seem* like it's up 24hrs a day, but it never is. The reason its up for a long time now and then is because of our high latitude, as I mention at 2:20
Sorry I haven’t catches up in awhile. You can also get your latitude from Tycho crater at moonrise and moon set. What’s your latitude? Can I ask you for a favor?
Well then maybe you can understand the question I'm about to ask. I've asked many times and every time I get gibberish in return. I don't think they understand the question or realize the moon is even different. When I'm in Canada the quarter moon is horizontal in the sky every time without fail. When I take a 5 hour plane ride directly south and look up from Mexico the quarter moon is almost vertical. Just like in NASA pictures. I never understood why all NASA photos had the moon wrong until I saw this for the first time. Why is the moon laying sideways from such a relatively small distance change? I've tried to recreate this with lights and toy balls on wire but can never get the result where the shadow is either top or bottom. Without changing the position of the Sun.
I *think* what you're describing is related to two things: 1) The moon terminator illusion, and the fact that the further you are from the equator, the greater that illusion is. See Vsauce: th-cam.com/video/Y2gTSjoEExc/w-d-xo.html
Where is your location, and what time do you see the quarter moon? I've made some videos on similar topics so I want to see if I can answer your question.
If you look on TH-cam for videos of moon orientation based on latitude, and time of night, they show that the orientation changes based in time of night and latitude. A program like stelarium can predict exactly what the orientation will be based on location and time.
I live in Vancouver, yup! Yeah, its been the cloudiest July I've ever seen. Months ago I planned to make this video in the summer so that it wouldn't be cloudy. so much for that plan...
Ok, that's *Crazy!* I did not know you could tell time like this. I'd LOVE to see how the Flat Erffers can explain this on their none existent model. Should do for another laugh. ^_^
OK, so I tried to use this when walking home in the evening and I just couldn't make it work and only later I found out it was a partial eclipse of the moon so what looked like a growing crescent was actually a full moon...
As usual very well made .. but I thought you were even going to go out and try your luck at really predicting the time based on your coordinates and the angle of moon and the day of the year and other stuff .. but yeah it was a good video ..
I so so wanted to do that... It was the plan, but its been weirdly cloudy nearly all month, and I kept making this video and hoping that I'd get a chance to see the sky before it came out, but no luck :(
You can guess the position of the sun based on the phase of the Moon and it's position in the sky. That's a simpler way of guessing time. I was able to guess the time images based on that.
It would, yeah.. I was just trying to show 6 hours as it being halfway from east to west - but I didn't have a full 180° of rotation to work with in this shot. Good eye!
Things you don't want to say... in other contexts. Or alternatively: The script of a really odd porn movie. Maybe they ran out of budget. ...Idk where I'm taking this joke, but I'm leaving now. Have a good day from me too!

I never understood why all NASA photos had the moon wrong until I saw this for the first time. Why is the moon laying sideways from such a relatively small distance change? I've tried to recreate this with lights and toy balls on wire but can never get the result where the shadow is either top or bottom. Without changing the position of the Sun.
I *think* what you're describing is related to two things: 1) The moon terminator illusion, and the fact that the further you are from the equator, the greater that illusion is. See Vsauce: th-cam.com/video/Y2gTSjoEExc/w-d-xo.html
Where is your location, and what time do you see the quarter moon? I've made some videos on similar topics so I want to see if I can answer your question.
If you look on TH-cam for videos of moon orientation based on latitude, and time of night, they show that the orientation changes based in time of night and latitude. A program like stelarium can predict exactly what the orientation will be based on location and time.
You can also look up mooncalc on Google and you can see the moon orientation changes based on location as well as time and date.
I didn't know you live in Vancouver, I thought you're from Victoria, the weather's schite, eh
I live in Vancouver, yup! Yeah, its been the cloudiest July I've ever seen. Months ago I planned to make this video in the summer so that it wouldn't be cloudy. so much for that plan...
@@ScopeofScience at least it wasn't smokey
Wow, very interesting!
Now I can brag my knowledge to my friends xD
Ok, that's *Crazy!* I did not know you could tell time like this. I'd LOVE to see how the Flat Erffers can explain this on their none existent model. Should do for another laugh. ^_^
Regards from Colombia, very interesting video !!! Keep it up 👍
You should do it at desert, that makes it slightly easier.
OK, so I tried to use this when walking home in the evening and I just couldn't make it work and only later I found out it was a partial eclipse of the moon so what looked like a growing crescent was actually a full moon...
Nonsense
about the "you dont need good gear to make youtube work" look at Cody's lab as prove for this statement
Right!? Yes. This.
Please make more science videos like you did a year or two years ago.
I'm working on it :)
Why didn't you use Stellarium, it's awesome for exactly this. :)
love your vids
Why does he look like Stewart from The Big Bang Theory?
i swear i learn more from you than my science teacher wut
Science world? In Vancouver BC I live here
Science World!
As usual very well made .. but I thought you were even going to go out and try your luck at really predicting the time based on your coordinates and the angle of moon and the day of the year and other stuff .. but yeah it was a good video ..
I so so wanted to do that... It was the plan, but its been weirdly cloudy nearly all month, and I kept making this video and hoping that I'd get a chance to see the sky before it came out, but no luck :(
You can guess the position of the sun based on the phase of the Moon and it's position in the sky.
That's a simpler way of guessing time. I was able to guess the time images based on that.
Just a reminder it's all upside down and backwards if you're in the southern hemisphere. Fortunately, it doesn't matter if you're left handed.
3:08, 6 hours would mean 90° rotation, right? You rotated the globe only 45°.
It would, yeah.. I was just trying to show 6 hours as it being halfway from east to west - but I didn't have a full 180° of rotation to work with in this shot. Good eye!
I accidentally came early today! Have a good day everyone!
Things you don't want to say... in other contexts.
Or alternatively: The script of a really odd porn movie. Maybe they ran out of budget.
...Idk where I'm taking this joke, but I'm leaving now. Have a good day from me too!
@@R3dFlames Haha, that's just straight gold right there.
Hi!
A "moonth" isn't that far off. In Dutch the word for 'moon' is 'maan', and the word for 'month' is 'maand'.
Why 4:21 not 4:20
Come on man
It seems like you were almost whispering when you were in that room. Is there a baby asleep or did you sneak into someone’s house to film this?
