- I misspoke a couple of times (303 instead of 333, 2023 instead of 2022) but the correct number was always onscreen. That's what I get for doing it all in one take!
- Yes, I mooned the camera. I'm just that on theme.

Such a fantastic use of editing!!!
Matt is a clever boi
I ve already got used to that. He uses this technic in every video.
I was more surprised his camera wasnt damaged from staring at the sun
Plus they both did the "hey my hand is empty now" wave right afterwards!
Captain D should debunk
The thing I love about your videos is that all this stuff comes straight out of your brain. It never ceases to amaze me. You truly understand math(s) on a deep visceral level which I find incredible. We really enjoyed the dinner with you and Lucy in Argentina! Thanks for being such a stand up dude, both on and off camera.
Great to see you both again! Thanks for making the time to catch up. Was fantastic to see the rest of your amazing joint adventure.
Destin with the "stand up" puns. I enjoy both your channels! Thanks for making this video happen so we could experience it.
We really live in the best timeline. Makes me so happy to see two wonderful minds who have come to fame purely for their brilliance and kindness be able to collaborate and communicate so candidly.
his words are braking my bran!!!!
Destin, us Brits rejoice in your bracketed 's' !
"I have a scale model of the Sun and Moon here"
"This is not to scale"
They're scale models.
Just at different scales.

phew I guess he made it
when he was babbling "like, subscribe" etc. i was screaming just shut up and go watch it XD

A parker eclipse?
yes.
What are the chances?

"that's our 2000 day wedding anniversary!" honestly that is so sweet i cant remember most yearly anniversaries
They don't celebrate their Gregorian anniversary. They do a round base 10 number of days. It may be 400 or 500, I'm not sure.
We celebrate every 500 days.

@AlastrionaCatskill Why base 2? What's wrong with base 10?

Says 333/106 is his favourite approximation of pi. Calls it 303/106. Classic Matt Parker.

Solar eclipse: Exists
Matt on July 2nd: "There's still 257 days until the next pi day, but maybe they won't notice if I try to estimate pi during the solar eclipse..."
Sadly, he missed 22/7 as an upload date
If you look closely at 10:15 you'll actually notice that there are not one but two moons visible. Absolutely breathtaking.
10:16 That's a Parker mooning. I am just glad it wasn't eclipsing the sun.
i’m glad i wasn’t the only one who saw it ....
When the eclipse happened over the US a few years ago, my wife and I decided to drive up from Atlanta to get to the full eclipse. It was kind of a last minute decision, and we did not have any solar filter glasses, and could not find them for anything that was not an insane price to save our lives. But we went anyways. We ended up in the parking lot of a grocery store and this couple near us saw we did not have glasses and gave us their extra pair. It was a small thing, but it made all the difference in the world to my wife and I. If you ever get the chance to do a kind thing, no matter how small, do it. I will never forget being their for that eclipse with my wife, and those folks made it even better.
During that same eclipse, I was also without glasses. However the local science centre was giving them away, which is nice, but they ran out by the time I got there, which was not nice. But maybe someone would give me their extra pair? No. In fact I saw someone gave his extra pair to his dog.
Your wife must truly love you.
- So Honey, this is one of the most beautiful and haunting natural phenomena we will observe together. What do you want to do?
- A RUclips video?
- of course Darling... of course...
There aren't many things more beautiful than a man who can put food on the table.
1:01 you can see the partial eclipse in the lens flare near the bottom of the frame
I was just coming to post that observation.
Yes, I noticed that too! But he mentioned it at the end of the video though... (9:06)
It was great to see, then it was mentioned in the video also woo.
You should have done a Tom Scott and yelled "one take at the end"
Yuval Nehemia you put the quotation mark at the wrong place in the sentence
@@Rheologist nah, he just wanted him to yell "one take at the end" at the end.
Me: ”Give me one good reason to keep supporting you in the Patreon.” Matt: Travels half way around the world to read me continuous fractions during eclipse...
This is such an impressive video: very informative, wholesome, entertaining, capturing a rare natural phenomenon, and all in one take?!?
and with no possible redo
Nah, they had to retake, having the Moon step back a bit and come in again....
Fred
I'm just glad the other moon on screen was partially eclipsed.... Crack kills Matt!~ 10:15
Damn you best me too it!
@@doggfite Damn, me too! haha.
You good sir, won the internets for today.
Ha ha, came here to make the same remark. :D
That's no moon, it's... you know, something with an garbage compactor.
My one shining moment as a Lecturer in front of a University class was in the presentation of a Project to predict Solar eclipses back in 1987. I had totally forgotten about that until now here in 2019. Wow.
i absolutely love how supportive matt and lucy are of each other and their work.
at 10:17 there is a total solar eclipse and a full moon (bottom left :P)
Came here to point that out
I'm here to search for this comment
damn, you beat me to it!
in 4K60!
@@ReikaTAKANO same hahahah
I went to Argentina and saw it too! Incredible!
I like the little show of where the moon/sun are in the glare from the lens (the green one on the bottom, focused well at 2:30)
I was just about to say the same thing. Pretty cool stuff.
Happens throughout the video. Only noticed it when he took away the filter from the 2nd cam.
Was also about to comment the same. Light is weird. I hope another sciance youtuber sees this and makes a video about why the flare is projecting the image that way.
Matt comments on it near the end of the video. It really is worth hanging around till the end, if only to hear him (sometimes) make a little fun of people who dont XD
Nifty. I play paper and pencil role playing games (such as Dungeons and Dragons). In one of those games, I had created a world with a number of moons orbiting the world on which the game took place. I actually wrote up an Excel spreadsheet detailing their various orbits, conjunctions, eclipses, and so on (the world had rather crazy tides). I bring this up because some of the combinations would only occur once in hundreds of years, and there were a few that only came up one time in a 50'000 year cycle (which was the entirety of that world's history). This video reminded me of that spreadsheet.
Good to see you all in Argentina! I watched it too. Drove all the way from Mendoza to see it
So many lovely details in this video. Really a wonderful job that adds to the enjoyment of the event!
I was waiting for this video! I hope you enjoyed my country! So glad you took the time to travel and film it.. youre the best :) next time, let me know before you go and ill get the guides you needed for the cities ;)
What a totality awesome video. There is something very primal about witnessing a total solar eclipse. Glad you guys got to enjoy it together.
And at around 10:15 a second moon appears!
Or a plumber!
I came here looking for this comment. For extra points, frame step through to t:615.66
Pi Equals one.
It's too easy at this point.
Right order of magnitude. Close enough.
It's so silly that we're using a ten based number system, when we could be doing so many other things instead...
I’ll see you all October 25, 2023!
@@steamsuhonen9529 such as?
Ah, squaring the circle is now possible
My family and I got to experience the eclipse on August 21, 2017. It was a neat experience. Glad you got to see one.
Its always good to see when you are following two individuals and they then reference each other - good work - love your approach ...
Love the maths and the editing, great job as always!
1. Great video. Very impressed with how you can just casually spit this information out during an eclipse (or without an eclipse).
2. Nice bit of editing to digitally suspend the sun and moon models in the air.
3. Love the crossover of sorts!
Truly brilliant, the maths and the footage!
I just watched Destin's and the sum of the videos is pure joy!
Correction:
At 6:30 the continued fraction on the screen is wrong. The numbers should be 5,1,6,1,1,1,1,1,11,...
You say it correctly, but it's displayed wrong.
Matt you are the most dedicated youtuber I appreciate you so much
Lucy, thank you for being so long-suffering, in order to let Matt bring us more math joy!
I was gonna point out the crescent lens flare right away but decided to watch the full video first and sure enough you mentioned it. That was a lovely detail.
I love this. Giving me chills. The great conjunction comes.
Honestly couple goals, that was adorable and informative
I like that you can see the progress of the eclipse on the lens flare. Also the full moon at 10:14 that appears to be setting just to Lucy's left.
Thank you for your continued efforts to read numbers to cameras.
That was just an epic video! Congrats!
This made me laugh out loud with that whole, I’ll lust leave this here in the air bit. It also made me smile when u guys were excited to see the eclipse. That’s a rare thing. Fantastic video.
That bit about the moon shadow was really cool
I enjoyed watching the exposure change. A lot.
Wow! That fast forward effect showing the shadow of the moon in the clouds above you was really something!
That was fantastic! Thanks for doing all of that!
I totally got excited at 9:53.Brought me right back to the excitement of witnessing the eclipse of 2017.
A synodic month is added to my life expectancy every time I see Matt's visual effects!
Brilliant video! Just for fun: if you have one of those cheap & common 6"/15cm globes - a standard table tennis ball is very close to being a scale model for the moon. Give your friends or kids the globe and ball and ask them how far apart they would be to scale. Most people in my experience estimate a couple of feet or 50-70 cm. It should be about 4.5 meters (this from memory - somebody can correct me). Don't know why but this surprises people and me! There aren't many astronomical distances that can be shown to scale in this way.
Saw the eclipse in the US in 2017, a highlight of my life!
I've seen two partial eclipses from the UK in 1982 and 1999, I remember in the 1982 one I drove my parents nuts by covering the living room window with a black sheet with a pinprick in it so I could project the image of the sun onto the other wall!
Destin sent me. Beautiful video.
The shadow was incredible... Never seen anything like that before.
I'm onboard. Liked and subscribed.
This is why I subscribed to this channel
It is so sweet how they are so excited for it. That is so awesome
10:15 Second moon in the lower left
Having seen my first total solar eclipse in my hometown just in 2017, I was freaking out for you as the eclipse time approached!
This is brilliant. Many thanks for this video!
That was just such a great video. Thanks!
The way the sun visually rapidly shrinks as if it's going to disappear completely just before the eclipse is trippy even through the screen. can only imagine how strange it must feel IRL.
So basically, a perfect eclipse like this one is as likely to happen as the DVD logo (of the old saving screens) hitting the corner perfectly ?
Yes. I have spent many combined hours being disappointed.
I actually live in the path of the eclipse that crossed the US last year, and it was one of the coolest things I've ever experienced
The level of excitement when the eclipse actually happened almost made me tear up it was so fun and pure
I was lucky enough to have the August 21st 2017 eclipse land on my 18th birthday. Very special moment to experience.
0:56 That's the eclipse we all wanted.
"it's hard to see from the camera over there"
Lens reflection shows perfect eclipse ;)
I was looking for that comment! Saw it immediately and wondered if anyone else noticed )))
I loved Matt`s plumber butt there at the end!!! Love your math`s. Keep it up!!!! He mooned us a partial Matt eclipse!!
So cool to see even professors of physics still get excited by seeing an eclipse (coincidentally, i'm currently reading - and very much enjoying - Professor Green's book about the sun).
2:11 Ok that was pretty badass
I'm subscribing on the recommendation of smartereveryday. This is a high expectation, I wish you luck on achieving your goals .
Warp transitions....luv'em
10:15 quite possibly the only piece of live footage ever with a total solar eclipse, and an almost "full moon" in it at the same time.
There's a sweet lens flare version of the solar eclipse in the middle bottom of your video!!! You stepped right over it at 0:56.
It's very weird to think instead of enjoying eclipses this guy is making videos....... 😛😛😛😛
Wow, i really hope that you and your wife enjoyed the eclipse and the country.
Greetings from Argentina.
I remember my first eclipse, I was with my brother and mum shopping in a JJB Sports shop. The shop used a tannoy to explain that they were shutting the tills to view the eclipse and that any customers were welcome to join them in the car park.... so my first ever eclipse was also in a very exotic location!
I wish I knew you were coming to Argentina! I would have loved to say hello!
Got here from @SmarterEveryDay. I quickly got lost in the fractions but stayed for the excited person
Do a video on Induced subgraphs of hypercubes and

I've heard that it's an amazing proof! And I'm sure you'll find it interesting!
The effort he puts in this to educate ppl made it impossible for me to not watch the whole video.
I enjoyed this. Thank you.
26th of Decemeber 2019 will be my 30th birthday by the way :)
...which, yeah I know, is really not all that exciting (although 10 957 is a prime), but there's just some random viewer statistics data sample for you.
Anyways, hope you will have a great anniversary! :)
(And thanks for taking so much time out of your eclipse viewing to make this video!)
Took my girls to near Casper, Wyoming see the total solar eclipse on August 21, 2017. Definitely the coolest single two and half minutes of my life!
We had a partial solar eclipse where I live a little over a year ago. It was the first (and so far only) eclipse I've been present for, and I had to work that day :( But I was walking to work when it started, so even though I couldn't see the eclipse itself, I was able to experience the strange "aura" from the lighting changing to a dusk sort of level in the middle of the day. Even that alone was pretty cool; maybe one day I'll be able to chase down a total eclipse...of the heart.
"moon covering the sun" is also visible @0:00 to @0:15 as well, and @0:45 onwards, through that greenish reflection exactly in lower middle region of the video - probably due to internal reflections within the lenses of the camera, mitigating the incident light intensity - thereby resulting in clear capture of 'moon covering the sun"
Such a cool concept for a video! Seeing a full eclipse in 2017 in Dallas, OR was one of the scientific/poetic highlights of my life. No description does it justice, though there’ve been many attempts. See one if you can!
Very meta, Matt mooning us during the eclipse 10:15
"One of my favorite approximations of pi..."
There's probably only 333/107 people that even have a favorite approximation of pi lol
This video perfectly shows the diffrence between mathematicians and physicists. He is a mathematician so he does the weird fraction thingy. I am studying physics and therefore just used the harmoinc oscillator. Because everything in physics is just harmonic oscillators (and taylor series expansion) xD
Great video... Thank you!
Dr Lucie to be in more Matt videos 👍 is my vote. Also love the “sticky” sun and moon
Awesome video! I was in La Serena, Chile for this eclipse and made a live stream on my Instagram instead of an explanation on how eclipses can be calculated hahahaha
The total eclipse that I got to see was the most awe inspiring thing I've ever experienced. I've already planned travel for the next that comes my way.
1:47 "I'll give you the moon" Most romantic line ever missed. :-D Thank you both for sharing your wonderful experience!
Matt - ok - here's the deal. Our nephew and his family (with two boys aged 10 and 13) were visiting and I asked the boys if they like math as a school subject ... explaining to them that math is a representation of our physical world. (Weak explanation, I know.) Both boys don't like math. How can we generate in young students the excitement you (and your bride) display about math? Society wants THAT EXCITEMENT; we NEED THAT EXCITEMENT. BTW, great video. I'm posting this on Destin's channel, too.
I never realized how much of the sun in the sky is simply "glare", as you can see in your video the sun seemingly "shrinking" until it's suddenly hidden behind a small black circle. It's of course not shrinking but the amount of light that makes up what normally comes off as this big circle in the sky is so much less, we get a smaller circle. COOL
Hey Future Matt @9:12. Just wanted to let you know hat the flare you zoomed in on is not as accurate as one might hope. But just south-south-west of it, the flare continues to 2 marvelously accurate representations!
