I couldn't find a JWST shirt that I liked.... so I commissioned an artist to make what was in my mind. Here's the link if you'd like one too. www.bonfire.com/store/smarter-every-day/
years? more like Decades 😉. but yayyyy im sooooo stoked to see its first images and data. OH BOY!
Needed this thanks a lot :)
I can't explain how significant you are in my life Destin. You have inspired me to take physics and your excitement for physics is absolutely nuts. I aspire to become you when I grow older. Thank you sir
One thing I really want to know about JWST is what magnification it has. If you could provide an answer that would be awesome!
@SmarterEveryDay I can't describe how happy I am that you did this and how well you did it. You make such awesome videos. This one pulled the trigger for me to become a Patron. Well done Destin.
'Are you excited about that?' 'Yeeees.' Man that was precious.
You sound older than him
Feels like the same energy as Destin.
"You're the Man." "I'm one of many." This one won many hearts. So humble. 🙌🙌
When Destin first mentioned him, I went “hmmm” and then he spoke and he was great. :)
Sigma male answer.
Real experts usually will not say they are "the man". They know how much knowledge there is still to know, and how much collective brain power is needed to accomplish things or create a knowledge base.
İm the 333 like
Very true. But then again, what kind of person would reply "Yep, I'm the man."? Would be a telltale sign they most definitely aren't. :)
" I don't get anxious about stuff I can't deal with" - very wise words from a really amazing person like Dr.Mather, and a beautiful finale for this video! It was a real pleasure to listen to him!
Makes sense. I have daughters that stopped talking to me. I can’t change their minds so I put it behind. Life goes on with or without
@@njjeff201 That's not what he said. He said that when he has to worry about something, he actually does something about it and he won't worry about the resolution because there is nothing else he can do.
@@Bruniiiefy Why is it wrong? He's done what he could do. Now, what happens, happens...
A true stoic. Research Stoicism.
@@Bruniiiefy Not much you can do on a spacecraft thousands of kilometers away my friend. Don’t worry… be happy.
I love how Dr. Mather just radiates excitement and pride. It's one of the purest emotions I've seen. For me this is one of the greatest things that you can experience as a human being
Indeed, I got goosebumps when he explains what he is expecting from the telescope. I'm not entirely sure what he's saying but gives me goosebumps anyway, just from his excitement and enthusiasm. Thank you Destin for creating such great contents as always.
I love how at 13:50 when Destin asks him "are you excited about that" he just lights up up with childlike wonder, as if he's a young kid whose parent just asked if he's excited to go to Disneyland, because that shared curiosity is the real driver of projects like this. What a great interview.
He’s changing the world and the course of human history. To be a part of something so big has got to be exciting
My lord! Your father taught me about carburetors AND he worked on the JWST?! Thanks for sharing this with us all, Destin.
I thought he would be a really good mechanic ...... But now..😱 mind blown...
One very smart gentleman. Like father like son eh? :)
No wonder destin and his children are smart. It runs in the family
Could you imagine that “bring your dad to school” day when Destin rolls in
@@Sir_Uncle_Ned : Multi generational rocket men.
The room was filled with so much of Dr. John Mather's charisma and personality and thats why Destin's camera kept overheating
Then his charisma and personality seems to reach a lot of GoPros around the world.
._.) Maybe need some passive cooling upgrade, or maybe need a fan (silent fan) to keep it from overheating..
@@OneSingleBreath lmao
Watching this video on Christmas after the James Webb Space Telescope went into space successfully! SO excited to see what we see with it in about 6 months or so.
Yeah man, and can you imagine the next team might already be working on a new telescope project.
I'm hard to buy gifts for. This news is the best Christmas gift I've ever received.
Same!
agreed!! I believe it take a bit longer because each mirror has to align properly before everything could function properly, i read somewhere!
images release on July 12th!! so excited!
I wish I was as well versed in anything in life as this man is about this whole subject matter. What a comfort it is knowing that people like this live amongst us, and what a pleasure it is listening to him explain how this particular telescope will work. Thank you for this video
💚
It’s never too late to begin. Pick a topic you find fascinating and that you do not get bored of pursuing on your own free will, and you will not only become well versed but also potentially very successful in all respects of the word. Find, learn out of fascination, find reason to pursue, set goals, practice, apply your knowledge and experience in the real world.
"I don't get anxious about stuff I can't deal with." This is the way.
I turn 50 next year, but I've already adopted this philosophy just in terms of day-2-day life. It drives my wife crazy because she constantly worries about things that COULD happen, or MIGHT go wrong while I sit back being chill. I just plan the best I can, and then jump into action only IF something goes wrong.
SO Phreaking true were all too young to get it.............yet
this is the way of stoicism
@@manjindersinghsaini911 Indeed. You beat me to the reply. Anyone wanting to dive into this way should read Stoics.
Every parent does the best they can to raise children. Then you have to just 'let them launch into life' and not worry about them, because you did the best you could do.
"I don't get anxious about stuff I can't deal with". That is serenity.
Exactly. That wisdom is encapsulated in the Serenety Prayer: (God) Grant me the serenity to accept the things I cannot change The courage to change the things I can And the wisdom to know the difference
I follow the same philosophy hello from Australia
Simple wisdom from a very smart man.
That is wisdom I would say...
IT IS SO COOL your dad worked on this, these first images are amazing.
Man I'm dumb as a rock but this so fascinating and heartwarming. I love it when I see people getting excited about stuff they like/love. And I was excited about this new giant space camera to begin with. Man I wish we can learn much more about space from this project.
You don't have to be if you don't want to be
Of course Destin comes from a family of rocket surgeons. And I thought his dad was just an amazing lawn mower engineer.
Same💀
Ikr
Right? It's always like this
In the previous videos I was kind of wondering why his dad still treated him like a kid instead of one of the most important science communicators of this generation. And of course everyone will seem like a dumb kid when you are working on the frontlines of human exploration and technology. It all makes sense now.
Why can't he be both?
"Eyh, here's my Dad, he knows all about engines!" "Oh, forgot to mention, he worked on the James Webb Telescope too."

Love how Destin breaks it down for us. "That was a lot, but we can understand it." Such a good encouraging channel for students of every age!
Congrats to your Dad and Team on JWST's first image!! 😀😀
25:44 is life changing advice. Astrophysics and mathematics aside, this is an extremely brilliant man.
I mean the guy won a Nobel prize, I think he doesn't have to impress anybody at this point in his life.
His philosophy is so simple yet it makes perfect sense. I don't know why I haven't looked at potential problems like that before. Maybe because I am not a brilliant astrophysicist. Anyway hearing that was like a light bulb moment for me, and it sounds like it was for Destin as well.
@@ivanthetactical6072 It's a Stoic practice. Do what is within your power to do, everything else is external and beyond your control. Lookup; Stoicism, Marcus Aurelius, Seneca, Epictetus. Many Successful and powerful people are known to practice / have practiced Stoicism. It changed my life, from a psychological standpoint.
@Myrmadon …boy i bet you’re fun at parties
I was actually almost shocked by his answer and then I felt a profond respect for it. It made me realize that most of my life I worried for things I could not control and that kept me from focusing correctly on things that I can control in order to be more productive. And let me tell you the things I'm talking about are totally meaningless in front of the JWST. I actually am already terrified when I watch launches of spacecraft I only heard about, if I was building them I would stop breathing and faint ^^. I will try to progressively adopt this way of thinking in my life, thank you very much sir!
So excited for this satellite to finally go up. I have been waiting for this for a long time. This is going to greatly advance our study of cosmology.
I wonder what the first image will be
It’s really exciting. Wikipedia says the timeline for the JWST started in 1999. Not sure if that’s true? However here we are.
@@JaydenGarciaYT Me too. I am so stoked to be able to directly image extra-solar planets!
@@volcheq2041 Yeah, it has been super slow getting this thing built, for many reasons. But now, barring any unforeseen problems, we are about to see this thing off and ready for action.
Telescope*
One of the best interviews I've ever seen. Period. Thanks for giving us the opportunity to hear what Dr Mather had to say. These are the things that make me proud to be human.
Destin, I love how you present. You always exude excitedment and curiousity. Thanks so much for making this channel and sharing with us.
“When you’re seventy years old you get tired of worrying about stuff, and you say ‘we’ll just make a plan’.”
If I was there I'd have wanted to give him a hug! If he has grandchildren I hope they appreciate Dr. Grandpa.
I to am finding the older I get, the less I worry about things, so, I understand what he said. Life's to short to worry about things you can't control.
@@RyanRamboer-sv3pm Yea, big fan. I can’t help but think it is transcendent in nature, and we are seeing the shadow. It is mysterious but accessible, and yet infinite in depth.
@@RyanRamboer-sv3pm The colors can be represented as depth - 3 dimensions. You can imagine it as a huge towering mountain, or a deep pit.
@@RyanRamboer-sv3pm I have seen it represented like that in 3D, and it absolutely makes sense once you see it.
Destin: We're gonna cover the most advanced camera humans have made. Destin's camera: * heavy breathing
i can't wait to see what fakery NASA is going to show us with the James webb
so that's why it overheated, right?
Lmao.. very underrated comment😂
Some of the most knowledgeable people are the most humble , I remember my dad telling me that in Cornell University, the Nobel price speaker would make everything sound so simple and even if possible seat close to the audience and speak to them just like a regular person having a conversation . The most awesome super brilliant minds don’t see themselves from the perspective of ego . Both the scientist and the person making the video look super excited and happy about this project , this guy is in his 70’s and he is having the time of his life . Great documentary thank you !!
I love your videos so much @SmarterEveryDay. At 9:07 when he finished talking about the angular momentum of the reaction wheels due to sunshine and thus setting the lifetime of the observatory, is about where I would have lost it with another video. Cue: Destin with “ok that was a lot but we can understand it”. Love it.
The look of joy and excitement on Dr Mathers face as he explains things, is like that of a kid explaining to their parents all the cool stuff he learned at Space Camp. 🤣
it was so fun to see him talk and listen to him
Why isn't he masked?
@@chiefslinginbeef3641 interview was done pre COVID I think, dr Mather is now 75, he mentions being 70 in the video
He also realizes he's talking to someone who really knows his stuff, and not to a class of bored children or students
@@nrdesign1991 yaa that’s what makes this conversation more interesting,imagine if he was explaining this to someone who doesn’t have that level of knowledge on the topic,he would have just explained like we are launching a telescope to space to take some photos.
Can we all just appreciate the fact that Destin sometimes has a video planned for years and is slowly collecting footage as things are developing to show it to us as a whole when everything is finished? Another terrific video (or should I say documentary) there sir!
Right?! For a sec my heart skipped a beat, coz i was like.. wait… did i just miss the launch? … some James Cameron stuff right here!
13:52 that “YES!” is the best part of this video lol
Congratulations to your dad on the successful launch of the JWST!!
His excitement when he says "suppose the universe has got things even further away" says it all, this man is about to complete the work of his life
The James Webb Telescope is so powerful & can see so far back in time it can see Federal Agency NASA’s original promised launch date & budget.
They did it! HE did it
_[talking about the vacuum chamber]_ "That's cool - so do they put James Webb in there?" "No, only his telescope"
Haha what a pun. But for real, I think such an important telescope should get a re-naming after launch. The contributions of administrators are important, but they already get a legacy by being named an administrator. Many scientists and engineers who otherwise wouldn't get a legacy are the actual value-creation that is churned by such administrators.
I watched this video with huge excitement and interest. I was inspired with owe with the brilliance of space science and its creative engineering and even more with the knowledge, humbleness, and wisdom of Dr. Mather! What an outstanding human being he is! Our earth needs more people like him. Since the launch of James Webb, I've been following its journey and have learned a great deal about the science behind it. I have to admit this video is one of the best videos I have watched discussing the Webb. Your simpler explanations above and beyond what Dr. Mather discussed are excellent. Please have more videos on this topic. Well done.
Destin, this is an amazing video that I am just now getting to watch. All the things in the video were eye opening…however, the most profound thing to come out of this video was the humbleness and humility that Dr. Mather displayed and his profound statement of how to let go of anxiousness and be present and mindful for all things/problems that are brought up and thought of by others and then not worrying about it further since he has the confidence to know that they did their very best to anticipate and resolve.
I love that as he's talking about having two of everything, your single camera becomes your failure point XD
I only wish they had two of the whole telescope. One malfunction during or after launch, and it's over...
He really should be going out with more than one camera.
@@mytube001 the Ariane ppl are gonna be scared AF
Linus should help him to watercool it.
Parallelism.
"We think we might see objects out to a redshift of 20 to 30." "Are you excited about that?" "Yeeeeehhhhhss" There was so much enthusiasm in that "yes". I'm so stoked for this telescope and what new things we will see and learn!
yeah when that level of a nerd who is also 70 yrs old gets so excited he can't help but be giddy, you know it's going to be on a scale we haven't seen.
Prepare for sadness friend.
Put it this way - this thing is gonna make the Hubble telescope look like a kid's toy telescope.
Most people have no idea what the scope of something like that even means.
@@MFcitrous Says the person without the intelligence to be a rocket scientist.
Yes, you're right: "Fascinating" is a perfect word to describe not only the interview but this whole video! Thanks a lot!
Had to pause near the end to affirm the nugget of wisdom. Worry never fixed anything (replace worry with diligence). Stress is only useful in short bursts, if at all. It's easy now for me to not worry, but it took a while to get there, and it might be one of the best things you ever learned to do, for many great reasons. You maintain clarity, your energy reserves last longer, and you may live a longer life with longevity also for various of your capacities. You just function better without too much stress and worry. And maybe most important - you'll be happier.
Watching this thing finally launch, and then unfold, is going to be nerve wracking!
I appreciate you for using "wracking" rather than 'wrecking'.
I’ve been following the development of this for years. I agree! I’ll continue to be nervous about it through launch day and then all of the following milestones until we get our first good images about 6 months after launch.
@Capitalist Warrior I was wondering if it might have cameras on board so the engineers could see the progress, but I get they can get the same info through telemetry sensors.
Does anyone know when it's supposed to launch?
@Myrmadon Assuming that the “I” in your comment was intended to be an “it”, this is why your life has been equivalent to that of a mid-grade rodent. Congratulations, you win the Nobel rodent award for your comment.
This guy is awesome. So charismatic and humble, I could listen to him all day
For sure, he’s true blue.
… and is ‘positively,’ unquestioningly naive about the “foundations for believing lies.” Clue: NASA and ‘our’ military excels at THOSE propaganda craft$ !
@@cocoweepah really dude?
@@cocoweepah what are you talking about?
@@lukecrawford9180i think, even he doesn't know what's he talking about.
Those final thoughts of wisdom, and your understanding of it, was awesome. We often take the same approach during high risk military operations. There is a certain point where you have to accept the outcome, yet still have mitigation plans in place.
Thank you for sharing your dad with your KZhead audience. I watched this when it was posted, but now, after seeing the early spectacular results, this is even more interesting.
My brother was an engineer who worked on this for about 15 years. His department was responsible for testing the instrumentation that would mitigate the vibration during launch. I’m a machinist and he had me make him a couple of fixtures that held 3 accelerometers on the X,Y,Z planes. God I hope this thing works 😅
THAT IS SO FREAKING AMAZING! Hope everything goes well. Good LUCK!
My favourite thing about these sorts of videos is visably seeing the interviewee get more excited and passionate when they realise Destin actually has a good understanding of what they are explaining
@BrightForest it also means he can see which parts might need more explanation for the average person, or which parts need simplifying or an analogy. And he can get more in depth information out if the interview when they say something that might be interesting. It's something you see in teachers that are passionate about teaching, looking for different ways of explaining the same thing because not everyone will understand something from one particular type of explanation.
I love how accessible you have made science. Some of the greatest teachers in the world are those that can break down subjects to make them accessible. Love your work so much!
Awesome video, I feel like I finally have an inkling of an understanding at least about how this telescope works. And the way you had those camera overheating problems but still edited the video with other interesting stuff making the video just as good as it would have been otherwise was perfect.
That was one of the most fascinating interviews I've ever heard. I didn't know much about Dr. Mather before this but I'm a huge fan of his now. That man needs to be celebrated more widely.
This kind of people should be in the leading positions of governments. Not a Donald Trump…
@@XCray What does your world revolve around that your mind went to thinking about Trump? Let it go
You may be a huge fan but I became a huge freaking air conditioner of him after watching this video
Too right! He just radiates joy over what he's doing. Seems like a really cool guy to sit and talk with as well.
@@HoLeeFuk317 You know those people. They'll always find a way.
Being 79 myself and a retired Industrial ventilation engineer I’ve also learnt the same wisdom; but exceedingly cool to hear that a top scientist does the same! Chapeau to him and his cool interview!
Having been through the entire Large Hadron Collider (which is clearly in another field, but it is a giant giant engineering project never the less) watching them build the entire thing over a ten year period and have it fail catastrophically (spent a year in rehab) after 9 days after they lit it up? That speaks to the net effect of ESA projects. Should the James Webb be riding the Ariane 5?? They had issues with it till last year?????????? I don't think the ESA has the resources of Elon Musk or ULA????
I honestly wish I could have just seen the full interview of Dr. John Mather without any commentary on it, he is wonderful to listen to
You must be incredibly proud to say that your father has worked on this project, I got the chance to talk with Bob Warden about how he designed the actuators for the mirror and I was just proud that my career as a Surveyor meant we could 'talk shop' about his work. Your dad worked IN the shop, huge difference!!
"when you're 70yo you get tired worrying about stuff, you'll just say"we'll make a plan"" the greatest quote of all time.
made me cry a little, not sure why
25:46-26:16 I felt underaged watching this part. 🙂
Awesome. Most of us could stand to learn from this regardless of age.
It's one of the pillars of Stoic philosophy. Why worry about things you have no control over?
@@rkf053fitz two reasons. First, a lot of folks lack the wisdom to know they don't have control over certain things, especially now in the US. Furthermore, even if ego and hubris aren't a problem, anxiety disorders are a thing. Second, as an engineer, I worry about stuff outside of my control because it can have an effect on what I do control. When making a plan, I know success is never guaranteed, i.e., it's out of my control. I do, however, often have control of how I fail when or if I fail. I can take a path that should I fail it guarantees a certain effect and can preclude other, worse effects that could happen if I chose a different path. It's for this reason, unlike Destin, I'm unfortunately incredibly bitter and hold copious amounts of contempt for people in general. There are a great many "unavoidable accidents" that are actually avoidable and incredibly reckless.
I worked on the Etalon filter in the Fine Guidance Sensor, it's a really tiny piece of the whole project, but I'm proud to have contributed to it's development. I can't wait to see what new discoveries will be revealed!
We used an Etalon in a FPI setup at uni a couple yrs ago, that lil bit of optical magic is baffling. Now to find out what it actually does...
I would just like to point out how brilliant this video is. Every time Destin's camera overheated, he could have just edited that out and continued the interview. Why didn't he do that? Well , he had a couple of choices. Instead of showing us ads or only talking about how embarrassing it was, Destin chose to continue to educate us and bring more related knowledge into the picture. Chef's kiss. Flawless execution, Destin.
@13:49 I absolutely adore seeing this man, who is wiser, more knowledgable, and more accomplished than I could ever hope of being, briefly breaking from his otherwise disciplined demeanor to express un-withheld excitement about something most people might struggle to grasp the significance of
“A huge hexagonal mirror made out of 18 smaller hexagons” Ah, yes… hexagons are the bestagons.

That nugget of wisdom is essentially the Shantideva quote "If you can solve your problem, then what is the need of worrying? If you cannot solve it, then what is the use of worrying?"
The worry happens when you don't know which one it is.
@@5thearth I almost feel like that's where Dr. Mather's wisdom adds something... if there's something you MIGHT be able to do, then try, but once you've done everything you can, then let go.
And what if you only have one shot to fix a fault that was not predicted and thus couldn't prepare for, but there are several good options? Worry is natural and human, it's becoming overwhelmed with worry that is not helpful. Platitudes are vapid.
Except it's not that simple. Sometimes you think you know how to solve it, but you're not sure. That's where the worrying comes in. Or, you don't know how to solve it, but you know the negative consequences of that. Also a source of worry.
Beautiful, educational, thought-provoking, fascinating. I, too, loved his "I'm not worried" - and why - at the end. Thanks so much for your tireless, sincere and enthusiastic efforts to instill and champion the noblest human traits in all of us - curiosity, wonder, humility and wisdom.
I wanna see a long form interview with the “drop the bass” guy. He seems cool.
I waited in vain for them to play a little of: "I'm all about that bass, 'bout that bass; not treble." Fred
Yeah, I wonder if they ever played music over that system, you know, to test the equipment and so on.
I second this motion. Love cool men of Science.
13:54 that "Yesss" turns him instantly from a renowned scientist to a giddy kid. It's so cute
I think there will be a transition from assembling more and more complex devices in space towards actually building devices in space. In that sense, the complex assembly of the JWST in space is a step towards that ultimate goal.
Wow. These drawings are gorgeous! And the video is so informative and entertaining as always! Thank you, Destin!
"The work of many individuals", "....of what we've done"; it's so nice to hear someone crediting a whole team, instead of taking all of the credit. Bless this dude!
I totally agree.
You know someone is really smart if they can explain complex things in an easy way. Dr. Mather and Destin both have this ability.
This was great! Mather made it so simple and easy to understand the science and incredible engineering behind this project.
Such a pleasure to watch your interview video with Dr. Mather..the amount of information about James Webb project there is absolutely mind blowing to listen and perceive. Thankyou so much for this video.🤝👍 I hope this project will surely open doors for the future of Astronomy and space sciences. Congratulations to each and every hand and mind behind this marvellous project.💐
26:07 "When you're 70 years old, you get tired of worrying about stuff." Truer words have never been spoken.
At 54 I'm already feeling that. It is quite liberating.
This guy is so happy to talk about his work. You can actually see him get more excited as the interview goes on.
Probably helps that Destin understands a lot of this stuff and can ask good questions.
Amazing interview Destin. What a brilliant and articulate man. I love how he he is quick to credit all the other scientists involved before taking any credit himself. That is truly a mindset that serves humanity. Besides the incredible science the most valuable thing I learned from Dr. Mather was his wisdom of “letting go”. Knowing that once you’ve done your best there’s no upside to worrying is a lesson we can all apply to our everyday lives. That was beautiful.
Just watched the launch of this magnificent piece of engineering. It was awesome!!!
"the James Webb space telescope is about to launch" This video will age extremely well, it could have been shot anytime in the past decade! 😁
Yes lol hope it goes in 2021
The same goes for Artemis.
@@thesauce1682 2025? 🤔
Currently its on a boat on its way to the launch pad. Therefore, I assume the launch is happening
Haha. Hopefully it will be launched in the next year or so. Can't wait to see what it captures.
I love gold hue mirrors. Also, Dr. Mather's excitement at being able to detect 30× redshifts was pretty cool.
Yes the mirrors look great, let's hope the do not immediately by micro-asteroids or rubble.
Oh yeah, when he said, "Yeeeeesss", it cracked me up. It's cool to see this guy presumably living out his dream and see all that he has learned/taught come to life with this telescope.
That would be absolutely awesome!
"Yaaaaaaasssss!"
I really loved the way doctor explains and also answer of last question's was amazing. Thanks JWST Team and SmarterEveryDay
Amazing conversation. The best thing about this is the way that Destin and Dr Mather have been able to break it down for simple noobs like me. I really liked the way they talked about the Lagrange point and how the light in visible spectrum can expand into infrared spectrum and how the light in infrared spectrum can travel through space dust. Thank you for this. Looking forward to see the beautiful images that are going to going from James Webb Space Telescope.
Can't imagine the embarrassment you felt when your camera kept overheating on this guy's time! He was so patient. Thanks for sharing it with us.

The older I get, the more I appreciate the perspectives of people much older than me. Dr. Mather is such an excellent explainer of his work!
I am very happy to hear Dr. Mather mention something that I practice in my life....if I can not control it, then I have no need to worry about it. Deal with the results how they land, but to not stress yourself about the what if's. If you run around life in a stressed out mess, then this is advice that you need to seriously investigate. Also this video was very fascinating!
The details, tolerances, and margin of error are so amazing. Truly an incredible engineering project. Amazing what we are capable of.
Well, it has to be, there's very little they can about it, once its out there in deep space. It's just makes sense this way. Just wish, more companies can put this much effort, when we as consumers buy their products, though. Lol.
I love the fact that he can explain it so that I, a person with no background in physics whatsoever, can perfectly understand what he means.
That’s a real sign of expertise. An expert in a field understands the subject so well that they can explain it in ways that a layman could understand.
Why isn't he masked?
@@chiefslinginbeef3641 why would he be masked?
@N why? abusing power???? By keeping you safe,?!!!
@@chiefslinginbeef3641 YOU are the moron here. Think very carefully before saying anything else. And then stop. You contribute _nothing_ .
One of my professors dropped some similar wisdom on me that I've taken with me since. "Do the best you can, with the time you have and then move on."
Wisdom from elders is priceless. They have 50+ years more experience on the planet. It's great when they can bestow it and you can appreciate it.
Read 'Bhagwat Geeta'
It is so so true... from my 55+ engineer experience
My Father also said something similar (as Dr. Mather did) when I used to worry about grades. I miss him a lot.
"I wish it need not have happened in my time," said Frodo. "So do I," said Gandalf, "and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us."
That was a very awesome interview and his philosophy on anxiousness is something I'm definitely going to put into my own life. Thanks for that!!
Came back to watch this again after those beautiful pictures were released. Must be a proud moment for these people who put their effort and time for so many years and got the result, I hope was as expected as they wanted it to be.
This video is *so* well done: The interrupts with the further explanations are helpful and exactly the right amount.
I agree, it makes it like a few questions we would ask as laymen!
Call me silly/random, but i just want to do my fellow Science-Lovers a Favor, so excuse the Randomness but here you go, have some warm Recommendations, cause the Learning never Ends! -Sci Man Dan! -Oversimplified! -It’s ok to be smart. -Professor Dave Explains. -Krimson Rogue. -Practical Engineering -Michio Kaku. -Kosmo. -Legal Eagle. -Cinema Therapy.
I have to say, the nugget of wisdom hit me harder than the science. Thank you for creating this content and congratulations on 10M subscribers!
100% agree. I'd learned most of the JWST stuff here in other videos or articles (except the L2 point orbit, neat!). But that ability to know you have done the best planning you can do, and trusting in that work, has actually made me not worry about it unfolding correctly. Some brilliant people have done their absolute best work, and if it works out, will push us forward in our understanding of the universe. It's poetic.
The doctor is so excited about this telescope. It's so awesome to see his excitement and hope for the project. Love this.
Dustin -- this was the best episode (of many great ones) you've ever done, IMHO. And yes, the last five minutes passed on some wisdom that all of us (especially those of us about to turn 70, like me) would do well to apply to our own lives. Keep up the great work!
13:56 is probably the cutest thing. Real, nerdy and well contained excitement. Love for the craft of intelligent engineering. Great stuff.
"There's no such thing as analyzing anything well enough that you can be sure". I'm just an automotive technician and I cannot express how much this is true. THE BEST QUOTE IN THE WHOLE VIDEO
Somebody tell that to the Boeing Starliner team. (Too soon?)
So true!
JUST an automotive technician...don't sell yourself short. 99% of the population cannot do your job. We've never met, but there's no "just" to your job. (I fix my own stuff, but send it to you all when I bite odd more than I can chew!)
I was JUST an automotive tech, and now I'm going back to school for engineering. You can do whatever you want, even watching this video means you care about science.
This was about as good as it gets. Your knowledge of science really helped to make this a wonderful video. Thank you!
Love this video, might be watching it for the 3rd or 4th time. It's amazing to know about all the systems that make the JWST possible, it truely feels like magic, espacially since it's already on its way to L2!
Frankly Destin, we are incredibly lucky and privileged to have access to the high quality content you produce on such a wide variety fascinating topics. Thankyou.
"I don't get anxious about stuff I can't deal with." Truly a wise man. I've been looking forward to the JWST launch for at least a decade and have always been nervous about it potentially failing. If minds like that of Dr. Mather are in charge, then there's very little to worry about after all. Can't wait!
"in 2011 after wasting over $4 billion their budget was cut for "billions of dollars over budget and plagued by poor management" so it's no wonder Mather doesn't want to take credit for being in charge since almost the beginning. Because the runaway budget diverted funding from other research, a 2010 Nature article described the JWST as "the telescope that ate astronomy". Well after Congress cut it the astronomical community led by a Congresswoman ran a publicity campaign for why taxpayers need to pay for their research toys and they've gone up another $6 billion since then. The reason you put real managers in charge and not a Nobel Laureate who doesn't understand that the money has to come from somewhere. SETI after losing taxpayer money acquired the funding they needed, but they stopped having so much waste.
Thank you for helping us understand more about the JWST
I watched this video the day it dropped. But I never took the time to digest it. I remembered the James Webb Telescope today and decided to re-watch it. Now I wish there is a follow up video talking about the James Webb after it launched last year. Thank you Destin. You are my hero.
I graduated 8th grade when this project started, and here I am in my mid 30s in awe by the scientists and engineers who make this possible. This is what makes being a human so amazing, our shared curiosity with space and the willingness to learn about it. So exciting...yet we still have people who believe the earth is flat.
Those people will believe the Earth is flat even if we shoot them up there with the JWST because they can't see the other side of the Earth at every given moment. Regardless, the JWST is definitely awe-inspiring, and so are the possibilities that come with it. Here's to a long, successful career for our small little hunk of metal!
I just graduated high school. Such a nice way to end my school years!
Phone home ET. Truth is stranger then fiction elliot.
@@Danil-xw9rc ohkk we all know earth is not flat but u cannot just straight say that god isn't there Idk like 75% of nobel laureates believe in religion
I have a lot of bunnies in my yard. I don't think they are so cute when I'm trying to grow a garden. But this comment section has gotten out of hand, so I'll just say, I don't know why people are so weird about everything nowadays. I'll just leave it at that.
You can tell that Dr. John Mathers is truly a genius by the way he is able to explain everything Destin so simply. This is amazing to watch
Amazing interview that is soooo informative! Impressive you can get a chance to interview Dr. Mather, the guy who knows the every bit of JWST, plus being very articulate. Thank you for sharing the video. BTW, I like so much about what Dr. Mather said here: 2:15.
I loved Dr. Mather's attitude for problem solving. Thanks Destin ❤️
Started watching this channel when i was still a boy. Now im in my final year of becoming a engineer. I am working at Airbus right now and I am able to see stuff like the Sentinel 2,4 & 5; Merlin and also a Spacetelescope like that. Its soo cool to see my daily work on youtube and one of my most loved channels. I am hyped
I could listen to Dr Mather all day. An incredibly smart and well spoken gentleman. The type of person that you know has so much more interesting stuff to tell.
So many great little moments in here. From dropping the base to letting go of nerves. Thanks for such a fun and thoughtful and informative video.
Hi Dustin , thank you for the great videos. Looking forward to a new year with amazing content. Keep well
