How far away is it - Chapter 2 - Earth Distances (4k)

[@gkcook81]

I love these 4K "remasters" and they look amazing on my new TV! I know it took a lot of work and it's very appreciated!

[@lagerbeer1974]

The fact that Mr. David Butler explains this information and material in a way that even a beer guzzling dummy like myself can digest and understand this stuff, speaks to the brilliance of this man's mind. He is a TRUE GENIUS.

[@pedrodiaz5540]

lagerbeer1974 totally agree with you

[@christinestill5002]

Have never found series as fine as this,best on internet. Thank you, David.

[@yaronkl]

Agreed

[@oculusexanimi4882]

Mr. Butler has produced a great gift to humanity and we are thankful for the time and sweat you put in this masterpiece.

[@juangsalazar8128]

It is so amazing. idk how many times I've watched these series, so many times. The enormous amount of knowledge he packed into these. Bravo.

[@fallingzeppelin69]

This video book should be declared a global treasure. So many things taught to so many people

[@samuelgarrod8327]

It's wonderful to hear metric measurements in an American accent.

[@condensermike]

These are the best astronomy videos since the original Cosmos.

[@angelchiriboga3904]

And just a few- listen to DTTV- if you can handle the more advanced aspects.,

[@To_Orion]

I;m only in the 2nd episode and I feel like all my questions will be answered here without me even asking about them.. this is just amazing

[@ramyg5037]

Thank you Sir! for providing us with your vast knowledge of the methods used in calculating galactic distances. Thanks for the excellent video and the excellent animation/actual pictures of the earth and other celestial objects. All this knowledge is given away for FREE on youtube.

[@backyard282]

it is a complete shame this doesn't have thousands of many times more views than this

[@mystichammer6517]

Your channel is one of THE most fascinating and informative science/space channels I've come across on KZbin. Keep up the incredible work!

[@kennethdobos9755]

I am always astonished in realizing the vast immensities and distances in the universe. It has always fascinated me.

[@jabelltulsa]

I really enjoy your videos. They are interesting and they have a calm and deliberate pacing,. You are an excellent teacher. Thanks!

[@pkassies]

Thank you for your clear and calm explanation of triangulation. I have a 12 year old son who questioned the purpose of mathematics at class (this is ok, i understood the purpose of math when I was 20 years). I showed him your video and he realised its great to calculate distances that are difficult to physically measure!

[@Kunfucious577]

You have the best videos on astronomy. So easy on the ears.

[@pedrodiaz5540]

I’m glad you use The metrical system , thank you very much

[@emcgman]

I recently discovered your video book series, and, needed to thank you for creating them. Yesterday I watched the 'How Small Is It' series. Before I went any further, I had to tear myself away long enough to say how fantastic this series is. So excellently is the information presented, starting with what you see around you, and going from there. The technical aspect of the production makes it all the more enjoyable. You are providing a great service to science lovers everywhere. I too am recently retired, and am rediscovering my original fascination with atoms, and cosmology. Thanks, David.

[@howfarawayisit]

I'm glad you like them. Thanks for the great comment.

[@bizvalue]

Mr. Butler, you have rejuvenated my interest and awe of the cosmos. Thank you for your layman's explanation of our solar system, galaxy, and universe. I also appreciate your simplified (as reasonably possible) explanation of the scientific discoveries, theories, and empirical evidence that proves our physical existence. Again, thank you. A Friendly Fan, Paul G. Marquez, New York USA

[@Parsi-Pedia]

Regards from Afghanistan and thank you for your devotion in giving us the knowledge in cosmology.

[@BipTunia_Microtonal_Cats]

This channel makes me smile. And think. But it makes me smile while I think. Thank you for your service Mr. Butler.

[@wadesharp11]

Im on a David Butler binge! Great channel🥇

[@Yami-Nathaniel]

I only discovered your channel a few days ago, and I have to say, this is extremely interesting, well presented and narrated, informative and educational. Thank you.

[@JP-qb8qx]

Im only five minutes in, and am already blown away!

[@douglassmith775]

You've done some amazing work on this channel, including the videos and notes explanations. I think you're a natural born teacher. Thank you.

[@WhoDoUthinkUr]

Thank you very much for sharing your knowledge with us as a high school dropout I have been self educating .

[@mombof]

Thanks for making this series. I watch/listen the all your series every day. This in particular helped me understand which math my brain has been missing out on. You visually explain it in way, that my brain understands

[@badgerlife9541]

Thank you for giving me something so valuable to watch in the evening! Your videos are awesome.

[@Stirlingsays]

Thank you for the gift of knowledge.

[@Stirlingsays]

?

[@MrKmanthie]

probably "North County" part of San Diego county: nice area!!

[@Crondo420ReFrEsHe]

And it feels great, so much knowledge for my expanding brain.

[@yoyo54314]

i have to watch them twice,one for the beautiful music,the other for the excellent content.

[@TheCgOrion]

Thank you so much for all of your effort Mr. Butler! All of your topics are things I have thought about my entire life (37). I'm so glad you have put this information out there for everyone to see. I've always suffered for my lack of effort as a school student, later to come to terms with the fact that I have the mind and capabilities to do pretty much anything I set myself to. Unfortunately that's not how the world works. If your resume doesn't show that you've paid your dues (for lack of a better term), you don't really have a shot. Most people I know think of me as a network/computer/tech guy, but I'm as versed in many areas of interest as I am in the one I chose to get my degree in, so I understand your life long fascination with science. Hopefully it sparks wonder and interest in the younger generations, so a few won't make the same mistakes I have. I wish the people in my life that are the closest shared the passion I have for learning new things, as it's always better to be able to bounce ideas off of others than to be stuck inside your own mind. Thanks again!

[@garydunken7934]

Wonderful series. Crisp and clear explanations; it's so easy to follow. Thanks David.

[@Delphinus24]

Loving your videos Dr. Butler! Thank you for using the metrical system. The speed of your speaking is perfect. Not to fast, not to slow and boring. So enjoyable, well done! Thank you from Italy.

[@PAULLONDEN]

Indeed.....This man was such a pleasant discovery on this here KZbin....He proves there's still hope for the USA. I wished a person like this could be president ....but then..... one wouldn't wish that misery on him.... Greetings from The Netherlands.

[@gonzaloluna1989]

saw episode 11. loved it. here I am to see the whole thing. Thanks

[@tturner0051]

Same. I wonder why 11 gets recommended first? I guess it has the most views/likes of his vids? I dont know, but Im glad I found it, this guy is great.

[@darkentbg]

Mister Butler, it is a pleasure to indulge in such videos. You have my utmost appreciation. I hope you are alive and well and i hope we will get to see a new video. Take care sir.

[@GW28533]

Thank you for making this series.

[@mrnoedahl]

Thank you so much for all your time and abilities you are sharing with us. Your videos should be mandatory in all schools. I am a slow learner so I appreciate the way you take the time to teach even the simplest things. Not everyone has the mind that you have. Thanks for being patient. It is so beautiful to see and understand what the Lord has created for us. How wonderful and glorious are His works.

[@adag5813]

This is the best thankyou...it took me time to get your delivery rythem.. but fantastic work . Get your kids to watch these you wont get better....

[@minakumari9154]

Dear David this is the best video that I have even seen with very good explanations. Thank you so much 🙏🙏💋

[@SBKZMedia]

your voice... is so... relaxing.

[@iamheatstreak4099]

There are not even ads in this video! Thank you for your effort! I'm a software engineer just started after graduating, with the same passion as you.

[@howfarawayisit]

You're welcome, and good luck in your computer programming carrier.

[@oliviapeters8629]

This is one of my favorite series so far, on the topics of space.

[@the.rogue.roman.77]

I just appreciate your videos so much. You start with fundamentals and you connect everything beautifully. And I love the classical music as well. It's a cultural education as much as a scientific one.

[@silviosarunic6709]

best videos on youtube!!!!!!!!! thank you mr. butler! this is so great!!! :) you are so good at this! many people should learn from you! :)

[@gilbertramirez6626]

Thank you so much for your series. I became interest in astronomy at the age of 12. I am 68 now but don't have the math skills necessary. Thank You again.

[@raybulla]

I am 67 now, share your thoughts

[@gilbertramirez6626]

I was able in my youth to locate and observe the planets out to Saturn butI am interested in Deep Space Objects. This series has made the math a little less daunting.

[@antonfernando3630]

This channel needs more attention.. clear information

[@VeeraBun]

I just stumbled across your channel the other day, and I'm totally hooked. Awesome work!

[@howfarawayisit]

Glad you found it.

[@andrewford2783]

David, Thank you very much for spending so much time on putting together these wonderful videos. They are so informative. I too have recently retired and now have the time to blow the dust off my 150cm Newtonian and show my two young grandsons the wonders of the night sky. 🙂

[@howfarawayisit]

Grandchildren are great. Enjoy.

[@lashersquirrelslayer]

Great job Mr. Butler. Its a shame my want of math was crushed from me at such an early age or I would be an Astrophysicist. These types of videos help fill the sad loss I feel.

[@ravencole2740]

Join kahnacademy. It's free and very inspirational. start with basic arithmetic and work your way as high as you can. You can do it!

[@osbonoam]

Gorgeous backyard! 😍

[@anarchyantz1564]

Here I am in my backyard. David dude, your "backyard" is huge! Probably wider than my house lol. Oh also, great series, subbed :)

[@valeriebess2119]

So happy I found this channel! Your videos are helping me conceptualize information that I think will be foundational in my understanding and will help me soak up even more knowledge about space. Thank you thank you for your work making these.

[@SJtoobsox]

I love this channel. Thank you, Mr. Butler for passing on this knowledge

[@alexestevam]

So cool to see Stan Lee doing these videos and leaving that silly super heroes thing behind him. Kidding apart, respect for the work here!

[@yourtravelpostcard]

By far the best explanation - I hope you reach a million subs asap

[@ryannorthway2540]

Found your channel the other week and I've watched quite a few of the videos. Really great series. I love watching youtube science but most videos aren't as thorough or in-depth as the videos you make. Keep up the good work

[@AlidelOro]

Amazing content. Loved the way you explain complicated things in a simplified manner. Thank you Sir!

[@bowenflob8036]

Thank you so much for this series!

[@BoozeAintFood]

this series is wonderfully entertaining and Imaginatively educational! I would love to see a similar series on subjects like the history and future of space travel and technology, and possibly a more in depth look at known stars and their exoplanets. after all exoplanets are all the rage these days :D

[@st.bernardprojectst.b.proj2441]

🔒🔒🔒🔑🔓🔓🔓 You are going to be all day measuring that big backyard.I love it though it’s beautiful💯💯💯👍💯💯💯

[@realdenvermax]

very thorough and detailed explanations. i love this how far away is it series. i wish some of this info was taught more clearly in public schools, such as triangulation. we might have less "flat earthers" and "space is fake" people lmao

[@Canard712]

Ignorance does seem to be persistent, but education is a good remedy.

[@peterfiedfm5104]

Dude i love your videos, you do such a great job and i learn so much from you. Thanks for being you buddy

[@cdnerin]

I only just found your channel and this playlist today, quite by accident .... I have a feeling I'm going to really like it, I am fascinated by all things space-related the last year or two! I have a hard time wrapping my head around how far away things are, and the size of galaxies & starts & other solar systems, so this will be exactly what I need to be able to learn more! THANK YOU for your work filming/editing/etc! I'm going to let the ads play through to support your channel, and I've thumbs-upped and subscribed :)

[@mylesbishop1240]

CanadianErin I've found his episodes so killer. I can honestly say every single one of his videos are worth the time. I've even been promoting this channel to my friends and other science channels lol. Welcome!

[@cdnerin]

Thanks Myles!

[@channel34mil]

Just amazing!!! Thank you for helping me to understand complicated thins in a simple way.

[@havan56]

Beautiful update! I liked the original and this one is more polished in several ways.

[@0tt0z]

Thank you for making these video's. Great work!

[@robertcollins432]

David Butler, thank you and I look forward to watching the rest of your videos.

[@bhal9358]

Took Geometry and Vectors in University. Also Calculus. Your teaching methods and videos are great. 🙏

[@brianbell8382]

The Platoon theme @ 14:28 was a suprise. Liking the series so far.

[@a121509]

You mean Adagio for Strings by Samuel Barber.

[@ridefast0]

Your view of 'Yokyo; puzzled me until I realised it was 'Tokyo' presented in a South-East Up orientation!

[@shaunehuolohan5736]

Thank you. Great job. very well created.

[@sivasurrey]

Brilliant. I had watched Brian Cox and Carl Sagan ( From Archives). Both just praised the mysteries and few facts. These were presented dis jointed like priest praising the Lord. Here Dave Butler has chosen the basic information we needed to know and I can already feel it is coming in a joined up fashion. I have waited 70 years for this and that is how old I am. I am sure this will give such understanding to many mathematical students to study astronomy at least as past time like me. My suggestion for another series to make how the moon rotates the earth. On which Plane it is and explain eclipses more a accurately than me and my father both were taught.

[@KS622]

One hell of a backyard

[@cahal]

He's done well for himself!

[@MrKmanthie]

Now I know what you've been up to over the past year, besides the 2 great videos on "How Old Is It" ...you were re-doing your original videobooks. I like these newer versions. Very nice job! Hope you do more on the whole ΛCDM model, etc. in "How Old Is It?: Thanks!

[@guidovlaere]

Thanks for this super video! This was very helpful and interesting.

[@jackset7041]

Thank you David, it's very beautiful

[@SuperProtector]

Thanks for the video's .. practical uses of what I have learnt ... thanks for the historical stories for our development...

[@jessebauer0110]

First off, Thank you for all of your brilliant videos. But The reason for this comment is I wanted to suggest an idea for a new video if you felt up to it. I was wondering if you could explain our orientation in space and why people in the southern hemisphere have a view of the galaxy’s center, and people in the north cannot see it. Also why when the planet travels through a yearly cycle, why we are not able to see different sets of stars. I have come to somewhat understand it myself but only after 30 years of pondering. I believe this would be a successful video and also a very informative one. Thank you again Mr. Butler. I watch your videos on repeat. I love the intricate details that you explain, almost as much as I love space itself.

[@fredwaldman8214]

if you developed software 1/2 as good as you make videos it must be a awesome software! Thank you for your time on such good videos!

[@Tadesan]

I've been to Yokyo. Hard to find but beautiful!

[@unkelpipit7157]

Great video with the most simplest explanations. Keep up the good work

[@Iceman-Raikkonen]

Your channel is simply lovely

[@tome57a]

Mr. Butler, I have just discovered your marvelous videos and am thoroughly enjoying them. I do need to point out a mistake in this one, however. At 3:47 you have successfully triangulated on, not Everest, but its sister peak, Nuptse. Everest is the dark stone peak to its left, which, due to the camera angle, does not appear as high.

[@howfarawayisit]

Thanks. I've learned a lot from observant viewers like you.

[@tsachik]

At 3:44 there is a confusion between Mt. Everest and Mt. Nuptse. Mt. Everest is darker one on the left. Mt. Nuptse `only' 7,861m en.wikipedia.org/wiki/Nuptse.

[@shariatymozaffar]

All of your video is very nice . thanks

[@treasurecave431]

I cant think of any other a reason a person could dislike such a richly educational video other than triggered flat earthers

[@michaelgilbey2203]

You should have your own discovery channel program. Really interesting.

[@sergiosalamanca4475]

Hello Sir. Great educational videos thank you for sharing

You are most welcome. Thanks for the comments.

[@dariuswilkins4984]

6:35 i think aristarchus was able to figure out the distance to the moon and give a (not so close) estimate of the distance to the sun (8 million miles or something like that) in around 240 bc

[@Νικόλαος-ο2φ]

13:40 Athens is not. Propably are the Low Countries. The orange lights on the bottom is Belgium, yellow lights on tip is Netherlands and at the right bottom corner is Luxemburg.

[@richardmercer2337]

Within the last 30 seconds or so of this video, "Cepheids" is misspelled as "Cephieds". I'm sure you'll want to correct that. The series of videos is wonderful and I am enjoying it!

[@raybulla]

Mr David Butler Well done Appreciated

[@OSUHARDING1ATECHNICEXPERIENCE]

Isn't this video a report? Seems I watched this a long time ago but now it's listed as a new video?

[@howfarawayisit]

This is an update to the Earth segment of the 'How far away is it' video book. This version is done in SI units and with 4K resolution. Over the coming months, I'll be updating the other segments as well.

[@OSUHARDING1ATECHNICEXPERIENCE]

Ok. It's good info to watch again anyway. Thanks.

[@philsurtees]

Fascinating video. Especially that backyard and pool. He's explaining all about triangulation, but I'm not as curious about how far away the rocks are, as I am about what the purpose of the big cubical cutout in the rocks is? Why on Earth would you build a pool like that and what is the purpose of those rocks? Why would you have a bulge of tiles and paving taking up space, and eating into the pool - forcing a bottleneck - that way??? I just don't understand that pool at all!

[@howfarawayisit]

I love water falls.

[@SuspiciousActivity871]

Looks like a grotto under a waterfall. I see a lot of those where I live, where we also have to conserve water, so we trick ourselves into thinking we have bigger pools than we really do through visual tricks
