AWESOME job. Seriously, awesome! It was engaging, light but educational, and I could tell you really did your homework. I have interviewed a few people myself and I know how hard it is to stay in the conversation while also thinking of the next question, and I thought you did a phenomenal job here. No doubt it helps that he does a lot of interviews, so he knows how to roll ;) but man, the talk of pens was really engaging, I hope this goes viral in the pen world! Congrats again, this was really cool and I'm honored to have even watched it :) -Brian Goulet

I feel like no one has ever asked him about his pens and he has been so bursting to talk about them.

David, this was absolutely delightful. Thank you so much. It was so fun seeing Dr. Tyson geeking out over his special pens like the rest of us. Kudos on the interview.

I never expected to hear Neil deGrasse Tyson gasp "OH MY GOSH" at the mention of oblique nibs. Knowing such a cool and inspiring person of science is just as nerdy about pens as I am really just made my day!

"You've got to have good flow to feed a broad" -NDT

I'm late, but I'm ready for the 6 hours extended version of this interview.

Not many celebrities would take the time to actually put in an effort to engage like how Neil Degrasse Tyson does. You can tell every reaction is humble yet brutally honest and down to earth.

Awesome interview. I like the "Oh, just one more-- Oh, just this one more--" Yep, a true pen geek. Also, get Neil Gaiman for an interview.

16:07 "I don't like lines, I can make my own damn line" I'm watching this for like the 10th time now and I'm still cracking up with laughter lmao I love this guy

You. Fist. Bumped. NDT 'nuff said... Kudos for an awesome interview (landing it and doing a great job throughout). Dr. Tyson confirms he is a great person, and in addition to all he does, also speaks FP-geek!

David. Seriously, I am a big fan of Dr. Tyson and am peanut butter and jealous that you scored a video with him. This tops your charts. I follow him on UKposts as well. Only other fountain pen celeb that I can think of is Neil Gaiman. I know he is a fan of the Pilot 823. Man. Man. Man. You met Neil Tyson. Man. (Have I said Man enough?)

Tyson's excitement about how pens both express and can be used to express ideas was so visible. Thank you for making this contribution.

This was a damn good interview David. Really, freaking good, and more professional/thoughtful than many television interviews. For someone with 5700 subs on a youtube channel, you've succeeded in doing something more relevant and fresh than most people with millions of subs. But get that blazer tailored! your sleeves look like MC hammer pants!

"You need a great volume and good flow to feed a broad" - Neil deGrasse Tyson, talking about his "master stick"...

Niel just infodumping about his pens is just so adorable. Definitely worth watching even 7 years later.

This was fascinating. I met Tyson several years ago while he was filming the pilot of Cosmos. It was all completely accidental. I was called up at 2am in the morning to go to the production area and complete a few tasks because they were going to be underhanded. When I got there, I set myself to doing any one of the many things I needed to do, when I heard someone gossiping ''So we were at this restaurant in carmel, and the waiter comes up and very hesitantly asks... are you Niel Degrasse Tyson?'' Everyone began to chuckle. I looked up and responded, ''Well, was he?'' ''Of course.'' Me: ''Wow. Lucky waiter!'' Everyone looks at me oddly.... Them: ''Erm.... he's over there...'' I look up and a giant of a man comes walking over, and my tongue choked. All I could manage were a few slight pleasantries, but it was an awesome minute or two. His hands are enormous and he isn't afraid to drop a curse word here or there for effect in his stories. Stumbling across this was a gem. I have seen many many interviews with him over the years, it's singularly fantastic to see that same passion about something else entirely! I know Bill Nye is a thorough fountain pen writer, as well as Keven Spacey and Stephan Fry (British Comedian and 13 year host of Quite Interesting). All three would be wonderful personalities to include in an interview tour!

As a scientist, I loved seeing his note book. Thank you for the interview.

Thank you, David. I did not expect this.

As if I could love Neil any more, then he shows us the depths of his pen obsession. This man is a national treasure.

What a wicked sense of humour Neil has! And an absolute pleasure to listen too.

such a collision of my nerd worlds! you should do more interviews. i'm sure you could find other professionals who love the pen and paper world. (perhaps there are even composers who still use pens to write their music.) but this was great, especially seeing that NDT has the same passion for pens as he does for the stars. and that he's cool enough to share his time with you.

Great job! Made me laugh when near the end you say one more and he's so excited to be talking about his pens that he does three more. Made me think of how I am when someone actually shows an interest in my small collection. I'm fairly new to the hobby so I don't know any celebs that use fountain pens, but I'll definitely watch anyone you think we would enjoy. Keep up the great work.

As a Physics undergrad with a passion for fountain pens, this is fantastic!

I think an interview with Neil Gaiman would be most excellent.

Dr SBREBrown would be a perfect interviewee and maybe HE'D bring HIS Emperor! Fantastic interview with Neil, one of my favorite smart folks.

This man is pure gold. What a personality! He comes up with the vulture feather and says: "One day I'll be ready for this"... I fell off my chair laughing. Then later, being right handed, he explains his Waterman's left handed oblique: "I like to see where that angle takes me"... I love how precise he is with what he likes, and how he has a reason for it. Thank you so much for such a great interview!

One of the greatest interviews done, being a physicist and a fountain pen lover i highly appreciate your effort in putting this interesting interview together . I had no idea that Neil degrasse Tyson was a fountain pen addict like us , this is why i appreciate the details put in the informative questions . Keep up the good work

Unbeforkinglievable! Not only is everything about this extremely wonderful, you also got a big genuine spontaneous laugh from him right at the top of the show! Legend status, this is. Beautifully done, thank you!

OMG, never saw this coming. Speechless! This video is definitely underrated and under-watched. Tyson preaching a New Gospel on fountain pens and their real amazing potential.

"I love me some flexible nibs" lol -Neil DGT!

Who the hell knew Tyson was into pens? I love his and Sagan's work - lovely to run across this. Great to see his passion applied to our relatively anachronous hobby.

I've been looking forward to this interview.

This interview was a great idea, and I would like to express my thanks both to you and the amazing Dr. Tyson for putting in the time and effort required to make it happen. I am genuinely grateful. I have always wondered what kind of pen J. R. R. Tolkien used, both for his calligraphic work and his day to day paper grading.

Great interview! I saw Neil Tyson and fountain pens and nearly fell out of my chair to watch it. I think Neil would like the Visconti Homo Sapiens. While it doesn't feature designs of space, it's formation from basaltic lava is something any scientist would appreciate. Plus it comes in a 1.3mm!

Such a great interview! Absolutely loved this! Thank you for putting this together and doing this.

Hey David - great idea for the this interview! Truly different, interesting and something no one else is doing.

Great video, I loved hearing why he liked pens the way he does. Seeing his old lab notes was awesome, they are much neater than mine were.

I love how he lights up when he talks about his pens.. clear love. thanks for the video

great interview great questions

I saw this on Reddit and was eagerly awaiting this video. So far, it's held up to my expectations

Oh wow. This is amazing. My worlds just collided! Thanks for putting this interview together. I loved hearing you guys geek out about pens! It seemed like he wanted to keep going and talk more about the other ones he had in his case!

One of the most fascinating interviews I've ever seen. Melding fountain pens and astrophysics. Bravo.

This was such an amazing interview. I really appreciated it. I love hearing great thinkers talking about the physical tools they use. Thank you for this!

Man, what a treat, two of my favorite things in life together in the same episode!! Great episode!

Interviews with fountain pen collectors/users is brilliant idea. I truly enjoyed this one. Thank you.

Had no idea NDT was so into fountain pens! Great video with a great theme, keep up the excellent work

Fantastic video! I rarely have patience for videos, this one held me the whole time, and made me wish for more. Thank you!

waited for this all week

David, I must say I am extremely happy to see you connect to one of the greatest minds in modern times over a hobby that has everyone here enthralled. It's amazing to see how different yet devout everyone in this community is.

Very enjoyable Interview! I really like that you don't ask many standard questions. I'd love to see an Interview with any professional calligrapher.

This was an incredible interview! We ALL know about his work....but to hear that he enjoys Fountain Pens?! To hear him talk about WHY specifically he likes a pen? It makes me SO HAPPY that I can geek out with Mr. Tyson with fountain pens?! YES!!!

That was great! I thoroughly enjoyed every minute of it! Thank you, David.

This was such a wonderful video to watch. Im still new to fountain pens, but even as a kid i enjoyed the feeling of writing by hand. Now I get to experience this connection with others--especially someone like NDT. ❤️ Thank you for sharing this with us!

Thanks David, you've done well. You have combined two of my favourite interests and I look forward to watching more of you shows. The interview was very professional and relaxed. I connected with Dr Tyson's attitude and of course found his pen collection most interesting. I do appreciate his emotional link to the pens and I also share his fondness of different nibs. Although I have never seen most of the pens discussed, (and rarely likely to) it was nice to see the bond to his fountain pens. My interest is in vintage pens (without the flair) and am particularly fascinated by the engineering behind the early designs. Thank you once again.

This was an awesome interview, I'm such a fan of Dr Tyson! I hope he returns for another interview in the future. :) Thank you for creating this!

This was simply awesome! Keep up the great work, David!

Amazing video! Although the pens shown are out of reach for most people, it is great to see the collection of a renowned personality. I wish there were more such interviews on fountain pens with celebrities.

I already adored this man and he just got exponentially more wonderful to me! Another pen nerd! And his answer to the final question… just wow. I could listen to him all day long. He’s got an unashamed childlike wonder about the universe that’s infectious and inspiring. My day is brighter having watched this interview, and it’s saved for those days I could use a little more joy. Thank you for sharing with us!

What a treat--Neil deGrasse Tyson and pens in one vid!

3 years later I find this extremely enjoyable interview and discussion on fountain pens. Wow!

Thank you for a very interesting interview with a very interesting man. As a Norwegian I was not familiar with him, but I have already preordered his book. And it was a fine collection of pens he had.

I thought this must be an April Fool's joke. What a fantastic interview. It is so interesting to see the another side of a well-known person.

Great interview, David. Thanks for doing this wonderful interview.

Wow, how am I discovering this 4 years later?! Real gem! Such a good interview!

I keep finding more and more reasons to love NdGT.

It would be amazing if you could do an interview with Richard Binder.

I really enjoyed watching the interview, thank you

Such an enlightening interview. I love hearing people talk about their pen collection. Thanks for sharing!!

That was an awesome interview! Keep it up! Did he actually bought or was interested about the classic pen?

"You need good flow to feed a broad." - Dr. Neil Degrasse Tyson (2017)

This interview was a joy. Thank you for putting this together. Neil's enthusiasm for pens was a surprise (at least to me it was) and a joy to watch.

Amazing, I love hearing about famous people who use fountain pens!!

I think pen 0000 should be given as gift to Dr. Tyson!

I have found in my fountain pen collecting efforts that finding pens that are pure mathematics themed is substantially more difficult for some reason. A reason escapes me, since there are so many visually appeal mathematical properties or identities or constructs that could be used as themes. A graph depicting the roots of polynomials of infinite order is a rather breathtaking graph, even if I do say so myself. The structure of most Lie groups is often considered beautiful, aesthetically. The Fibonacci Spiral is a classic go-to. Bifurcation maps are fascinating. Yet most pens that are science-themed are physics, biology, or chemistry related. Such a shame.

Oh David this video is magnificent! Thanks a lot for the work you put into it.

What an amazing idea David! Kudos for an awesome interview. Hope to see some more of these.

Thank you for doing this! Do you know what kind of notebook he wrote his graduate notes in? It looked very interesting!

14:45 Well, actually, even rigid nib fountain pens offer a very different feedback on paper. They are simply less slimey and uncontrolled ;)

This interview made me extremely happy. :) Well done and entertaining! Thank you so much to all of the people and work that went into it!

I went to see Dr Neil Degrasse Tyson on Valentine's Day in Dallas! It was truly amazing to be in his presence. What an honor for you to sit down and talk to him. He has been a positive outlet for me. In a time of complete darkness he brought light back into my life. I would give anything just to shake his hand and say thank you.

I am an admirer of Neil. And knowing he is a fountain pen user as well raises my esteem to another level.

"You gotta have a good flow to feed a broad" -- That moment when you realize there's an overlap between good penmanship and becoming a rap star.

I just stumbled upon this interview and what a great time I had watching it. What an amazing interesting man. He is so inspirational and I would have loved to see more of his pens in action. Great job David, to interview a person with so much information, enthusiam and knowledge.

I thoroughly enjoyed this interview! It combines two of my interests -- astronomy and fountain pens. This was an absolute delight to watch. :D Thank you!

Save the human race #ElectAScientist #Tyson2020 I can see him signing executive orders with that pink flamingo pen

David, don't look at your notes so much while interviewing someone. It distracts. Pretend like you're engaging rather than worrying about the next question.

Loved it, great interview

Really enjoyed this, thanks for posting!!!

Fantastic interview! Thank you for your work on it!

Two of my favorite things in one video, physics and pens. Thank you for making this video, it was amazing!!

i really enjoyed this interview. great job!

I really enjoyed the interview and am looking forward to watching future and past videos. Many thanks for your dedication, enthusiasm, and passion.

Really a fantastic interview. Loved every minute of it and will most likely watch it again. Great job, thank you!!

Your videos are usually great.. but this was something else. Thanks David

So awesome! I've been looking forward to this interview all week. I would love to see an interview with Neil Gaiman, like many of the other commenters on this video.

Love that he wanted to show you ALL the pens :) Really great interview and time well spent watching. Thanks for sharing this with us!

Great interview! I would like to see an interview with Neil Gaiman. Thanks!

Thank you, excellent interview! Dr. Tyson has a great sense of humor!

Thank you so much fro this interview! Dr. Tyson communicates the things he is passionate about so well, and you did a fabulous job with the interview/ photography/videography/editing, this was an absolute treat!

Absolutely amazing! Thanks so much for sharing this experience with us.
