Thanks for making such an incredible show Kelsey! You started coming out with videos right as I took my first upper level math class, and I think these videos are part of what keeps me motivated to pursue a PhD. Thank you so much for all the incredible work and time you've put into this and good luck with your dissertation! We're all rooting for you here regardless of where you end up!

All the best with your dissertation Kelsey! You will definitely be missed. We look forward to calling you "doctor" some time in the near future 🙂

Welcome back, Gabe! Long time no see. And a warm welcome to Tai Danae as well! (Hope I'm spelling your name right.) Can't wait to see what you guys have in store for us. (Runs off to check out Mathema.)

wow, fairs. im studying the heat equation in PDEs and to solve it in 1D takes like 15 min xD cant even imagine how long it would take in 2D. also, you are very good at explaining things, so i assume you have great knowledge. good luck with your research.

I gave "don't like" JUST BECAUSE YOU LEFT. I have to say I really liked to watch series not because of math them but mostly because of choice of topics. Really thank you to be host and wish you best luck.

Ok, you are, in my opinion, the best host in all of the PBS channels. The whole video, I was sad and remembering how I was sad when the same thing happened at PBS SpaceTime. Then you introduced Gabe. 🙂 I'm still very sad that I can't see you anymore, but at least I can watch other video's hosted by Gabe. I'm gonna go cry now.

Man, I'm not always one to comment much, but I've greatly enjoyed the series so far. Thank you Kelsey for the great episodes, and for leaving it in great hands!

I really loved this channel, it gave me a lot and, though I love maths, this made me love it even more, I never knew math was that beautiful, I never knew what maths exactly was!

You opened all the possibilities, and ofcourse including many confusions… But that's the cool part of it! Infact it is that moment when it gets interesting..

Thank you so much for spending your time in spreading the beauty of Mathematics! it is Infinitely appreciated ❤❤❤

Noooooooooooo!!!! Please come back. How selfish of me but you were so awesome. Best wishes on your dissertation (I hope you are working on a quantum heat equation and QDD).

Noooooo just when I was starting to enjoy it. I guess I'll go back to Numberphile now. RIP PBS Infinite Series.I hope you go into a science/maths communication & media career and don't waste your speaking talents on blackboards in classrooms.

I had a feeling I'd eventually watch this. YouTube isn't showing me things in the right order. But you are missed. I didn't think you'd disappear without saying, "bye."

It is naive to think over chess board plane as real plane. Chaos creates order in foam. Foam physics that is. That shape just scale out and in, like fractal. But for research maybe corrections are small. It would be useful to pass already heated plate near engine in buses without chemical that cool, Maybe magnetic force… MAgnetism or sound or heat… Look Robert Langlands too. https://www.facebook.com/cshlnews/videos/1698039323549826 Reminds me on EKG line diagram. Or Alcubierre warp drive, Negative spaces. Imaginary 1 or i. Can i be watched as prime block. I mean whole real thing is base upon imaginary i. Be rational or get real?! i over π. eiπ + 1 = 0 ( e^i pi+ 1 = 0 ) (x2 + 1 = 0) 82+1= 83

*sigh* Kelsey we miss you… Gabe and Tai were good and produced a number of great videos, but you are still loved and missed. And now that the channel is going dormant, it is a sad day for us all. :'(

I'm a highschooler who was looking for this video for a project requiring that an object stay at a constant temperature. Sometimes doing research on your own is so much more fun than learning from others!

Question: doesn't the exponential solution imply that the heat travels unbounded distances instantaneously? Immediately after applying the match, all points in the plan have nonzero amounts of heat regardless of their distance.

Now what would it be if you put the heat equation on some material that had a continuously changing insulatory factor, according to some function of space? Would that be like applying the heat equation to some curved space, similar to that which gravitational curvature effects velocities?

Thanks for the video and good luck with your research. Just a comment about the graphic around 7:10 meant to illustrate the slope of a line (e.g., to show what dy/dt < 0 means). The graphic seems to show 3 different (unlabelled) functions, one with positive slope, one with slope=0 and one with negative slope. The audio says the slope at x=1/4 is positive, at x=1/2 is zero and 3/4 is negative. e.g., there is a disconnect between the audio, which describes a changing function, and the video, which shows 3 different functions (e.g., when the audio is talking about the point x=1/2, the video highlights the point x=1/2 on all 3 graphs, which makes no sense). Anyhow, just pointing this out as someone could go back and fix the graphic to make this video more coherent. Thanks.

Respected Ma'am, in terms of types of PDEs, will you please give me an explanation of what is the type of Heat equation ? Parabolic, hyperbolic or elliptic ? Please explain . Regards Dr. N Das

So I looking to see if like magnitizem and reliogon mostly the exact same if you knew what reliogon really was but temperature maybe it to . Guess I look at refrigeration this more then I need to know to know the all

All the best with your academic pursuits.

Your research topic is interesting! Good luck with it. But don't forget to come back.

thanks for thhe video!

Good luck with your dissertation.

GAAAAAAAAAABE!

I love you Kelsey, but your use of orphaned operators in equations like d/dt = 0 makes me very uncomfortable

Thanks for making such an incredible show Kelsey! You started coming out with videos right as I took my first upper level math class, and I think these videos are part of what keeps me motivated to pursue a PhD. Thank you so much for all the incredible work and time you've put into this and good luck with your dissertation! We're all rooting for you here regardless of where you end up!

Damn. Gonna miss you Kelsey. (Thinks… "maybe i should get a life!") 😭

Thanks for the great videos Kelsey. Good luck with your research 😮

Welcome back Gabe!

What? Last episode?? 🙁

I cried at the end

We will miss you, Kelsey! 🙁 you did an amazing job with the show. Good luck with the dissertation!

Thank you so much for this wonderful journey!

I thought it was just q=smat

All the best with your dissertation Kelsey! You will definitely be missed. We look forward to calling you "doctor" some time in the near future 🙂

Welcome back, Gabe! Long time no see. And a warm welcome to Tai Danae as well! (Hope I'm spelling your name right.) Can't wait to see what you guys have in store for us. (Runs off to check out Mathema.)

her last episode?? nooooooooooooooooooooooooo (heart broken)

Please come back after you're done with your dissertation!

I'm really gonna miss those iconic hand gestures whenever Kelsey talks

Is Kelsey ever coming back??

GABE IS BACK !!!!wow

Thank you, Kelsey, and good luck with your thesis. Hope you'll be back some day

wow, fairs. im studying the heat equation in PDEs and to solve it in 1D takes like 15 min xD cant even imagine how long it would take in 2D. also, you are very good at explaining things, so i assume you have great knowledge. good luck with your research.

You're leaving?!? Nooooooooooooooooooooooo…..

I gave "don't like" JUST BECAUSE YOU LEFT. I have to say I really liked to watch series not because of math them but mostly because of choice of topics. Really thank you to be host and wish you best luck.

GABE IS BACK!!!!!

Eeeeyy, Gabe is back! 😀

But, but…… I love you 🙁

So the infinite series is finite…

Makes me so sad to see Kelsey go, she was absolutely amazing at doing these videos.

Will miss ya

I'm sad you are leaving.

really great to see this, such high level science free for all mankind, it give me hope on humans

Good luck with your research.

GABE!!!! NICE!!!! I'm so excited you're leaving!! 😀

I love this series … please continue !

Ok, you are, in my opinion, the best host in all of the PBS channels. The whole video, I was sad and remembering how I was sad when the same thing happened at PBS SpaceTime. Then you introduced Gabe. 🙂

I'm still very sad that I can't see you anymore, but at least I can watch other video's hosted by Gabe.

I'm gonna go cry now.

oh no dont go!

holy crap its the spacetime guy! omg omg omg omg omg omg breath pepe breath. hi gabe.

You are better than my lecturer a lot:) Thank you for your amazing teaching !

nooooooo!!! why??? ok you said why BUT STILL. are you coming back? 😭

Man, I'm not always one to comment much, but I've greatly enjoyed the series so far. Thank you Kelsey for the great episodes, and for leaving it in great hands!

omg gabe

GAAAAAAAAABBBE!!

GABE!! YOU’RE BACK!!!!

Sad to see you go Kelsey, but I'm looking forward to future videos. Good luck!

I really loved this channel, it gave me a lot and, though I love maths, this made me love it even more, I never knew math was that beautiful, I never knew what maths exactly was!

You opened all the possibilities, and ofcourse including many confusions… But that's the cool part of it! Infact it is that moment when it gets interesting..

Thank you so much for spending your time in spreading the beauty of Mathematics!

it is Infinitely appreciated ❤❤❤

Good bye Kelsey!💗

You will be missed 😢

Yes, Gabe! I'm not a fan of the long haired Aussie guy who took over Spacetime. Haven't really watched it since Gabe left.

Happy to see Gabe is back, loved his fast talking videos.Makes you always wonder how many lines he just had before the show.

this reminds me the Engineerong Maths from one of my unit in my university course

What great episode! You really helped describe these equations in a very meaningful way (and I have a math degree)! Thanks and good luck

man i was stuck studying for finals and missed this

good luck with the research, you will be missed!

also this is exactly a year since your first video damn haha

No Kelsey come back REEEEEEE

Good bye and thank you!

Whyyyyyyyyyyyyyyyy

Noooooooooooo!!!! Please come back. How selfish of me but you were so awesome. Best wishes on your dissertation (I hope you are working on a quantum heat equation and QDD).

X C16 OD

_____3 of 3 3T 4c# 8 ==Good luck..

you r genius….

Thank you Kelsey!

Come back soon!

NOOOOOOOOOOOO Kelsey was an amazing host!!!

Noooooo just when I was starting to enjoy it. I guess I'll go back to Numberphile now. RIP PBS Infinite Series.I hope you go into a science/maths communication & media career and don't waste your speaking talents on blackboards in classrooms.

Do a video on intuitionism/intuitionistic logic

Hope you'll be back one day after your dissertation is complete. Thank you for all your work on this.

There time flows much slower that on twitch, and far more educative. Thanks for videos.

ahhh she cant leave that's so sad !

Why Kelsey, Whyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

Thank you… Your life, and time in creating this series have surely inspired many, and have in some way, bring something in the life of many.

You people always make us like you and then leave…. Fine go, serves me right for getting all up in the maths.

Did any one find out if her left finger squares a circle?

I had a feeling I'd eventually watch this. YouTube isn't showing me things in the right order. But you are missed. I didn't think you'd disappear without saying, "bye."

eiπ + 1 = 0 ( e^i pi+ 1 = 0 )

(x2 + 1 = 0)

82+1= 83

Now I know where you went, looking forward to seeing you return.

"Hello, this is your dissertation calling." Good luck! It's a real challenge to work through those.

Heat equations show up all over the place… my favorite was as a data smoothing method.

Why did you have to leave, now the channel is defunct!

*sigh*Kelsey we miss you… Gabe and Tai were good and produced a number of great videos, but you are still loved and missed. And now that the channel is going dormant, it is a sad day for us all. :'(I'm a highschooler who was looking for this video for a project requiring that an object stay at a constant temperature.

The same equation is also applied to neutron diffusion in fission reactors.

When you know how to do calculus in high school and you get irritated that she doesn’t use calculus terms.

🙁

Now what would it be if you put the heat equation on some material that had a continuously changing insulatory factor, according to some function of space? Would that be like applying the heat equation to some curved space, similar to that which gravitational curvature effects velocities?

😞

I so needed to see this. Very important to object detection in point clouds IMO.

What?!? she was the cutest teacher ever! and she did great geography lessons too of course.

My Gabe-Babe! Still a sub of spacetime, but I’ve missed you!

Please, come back :'(

i'm a child

But… I thought this series is infinite 🙁

Anyway, good luck with the research work!

All the best for your endeavor , we gonna miss you … 😊😊😊

So I looking to see if like magnitizem and reliogon mostly the exact same if you knew what reliogon really was but temperature maybe it to . Guess I look at refrigeration this more then I need to know to know the all

I really love this channel 🙂

So sad to see you go and the end of this series.

What about Fourier heat equation violating special theory of relativity…..
