Guitar: I use an electric acoustic guitar, and transcribe pieces easier for me to play. Earlier clips here were edited, but recent clips are in original form, and reverb is coming from the amp and the room. Thanks for listening to my guitar.
Mathematics: I would like to share some ideas and understanding.

Thank you very much!
This is amazing. As a math teacher. Thank you! Kids usually don't appreciate this kind of effort but I like to do it anyways. Thx.
Do you know the strings' lbs information?
The highest is the top E string with 15.43 lbs, and the lowest the B string with 13.23 lbs. The remaining strings have about 14.3 to 14.7 lbs. See the information below: www.stringsbymail.com/hannabach-silver-special-815slt-classical-guitar-strings-full-set-376.html
Thank You. works well.,
woah
Thank you sir!
Amazing!!
Thank you for these, Dr. Chang! The elements of Inkscape looks similar to those of TikZ in LaTeX, if you are familiar. It looks to me like clickable version of TikZ.
Rest in peace Prof. Mirzakhani.
This is awesome!!
Ah, thank you so much! This infimum and supremum thing was driving me crazy making me thing why not use max and min instead? Well, now I know!
Glad it helped!
Great job.❤
👏
is there an actual way in Inkscape to calculate this graph, to increase precision or to stay scientific? thanks.
Under the menu Extensions > Render, there is Function Plotter. We can use this one to plot functions composed out of the standard functions within Inkscape. I would use other software or web sources, though, to generate graphs in pdf and import into Inkscape.
May I know which version have this latex option. Could you please share the link to download. Thank you
what about mac users I can not find the auto completion as you describe :(
I am sorry that I don't about Mac

How do I make the Cartesian axes, in such a way that they are totally perpendicular to them, because they are always crooked?
I think you hold the Ctr key while drawing an arrow, and it makes it perfectly horizontal or vertical.
Great explanation! You are the OG!
great thank you
boo. Descript has a poor amount of tutorial content. The interface looks totally different now.
the robot voice is horrible
Wonderful playing. Thanks for your you time in demonstration.
This video was helpful, thank you!
i was having a lot of issues thinking that my age was affecting my playing but I changed to these strings and I feel I'm back
Dr. Chang, this whole video series is very very useful. Thank you so much for uploading this!
Thanks for using them.
Eventually Robert de Niro gave up all gangs and turned into teaching math.
Fiquei muito agradecido ao Dr. Ruey Yen, através dele, conheci esta bela obra. É Parabéns a você pela bela interpretação,
Thanks Joao Silva for listening. I appreciate it agreatly.
My name is Flávio, I work with video editing using a wacom tablet. I've been searching for a solution to a problem I'm having for some time without success. The wakon tablet has a function called Keystroke, where you program a sequence of functions in a certain order. The problem is: if during the sequence of functions a function needs more time to execute completely, like "Save" the wacom tablet doesn't know because it fires sequences at a constant interval between one function and another. So the program is still doing function two and the tablet orders it to do function 3. Then the system crashes. Does wacom have a timer function between two functions? Will I get another brand of tablet that has this? Thank you very much
wonderful explanation
This is also relativistic geometry or chromogeometry -- Professor Norman J. Wildberger. Red relativistic geometry is dual to green relativistic geometry synthesizes the blue relativistic geometry -- the time independent Hegelian dialectic. Blue relativistic geometry = Euclidean geometry. Hyperbolic geometry is dual. Ellipsoids are dual to hyperboloids -- linear algebra, matrices -- Gilbert Strang. "Always two there are" -- Yoda.
Thank you. Love and blessings.
Great explanation!! Thanks sir.
saved me a lot of time, thanks man
Great
Gorgeous ! Best one I heard yet on youtube.
I feel this sudden nostalgia hitting me I remember when I used to draw like this as a kid 😢
How would you over lay two videos but have parts of the top video transparent? If that makes sense? Like having two people in the same room but recorded at different times and places how you’ll I put them in so it looks like they are in the same place. That’s using shortcut of course

wow thank you so much i am studying in one of the best university but my prof can not teach us as you teach me thank you so much
Very Helpful! Thanks man!
i cant add text, only a title how come
Thank you so much sir
Hi, is it possible to Tracebitmap only a part of an image? when I clip a part of an image as you showed in the first part and then tracebitmap it seems to bitmap the whole image and not only that clipped part.
me too. 😅trace whole image make slow.
Great series, lots of useful tricks thank you!
Thanks for using the video
Why they don't teach It at college
👏👏
55:45 Any quotient of H by a finite index subgroup of SL_2(Z) has finite area. Since the measure on H shrinks rapidly as you approach vertical infinity it's easy to see that Y(0) has finite area, and any such quotient can be covered by finitely many SL_2(Z) translations of Y(0).
i dont know if its your skilled playing or just my personal preference but that sounds heavenly!!!! thanks very much for the rare video i only just changed to low tension from Hanabach and thinking of going for the SLT strings and couldnt find any examples. but now im confident to get the SLT that just sounds sooo beautiful.... even with the LT i find the sound to be so warm and beautiful i just love it! especially on my hybrid flamenco guitar i didnt think it would sound so amazing so looking forard to the SLT!
Being warm is probably one way to describe the quality you get out of the set. It is the expression I pursue to generate that "sweet" sound with lovely vibrato here and there. The low tension string set suits me for that purpose. Especially it is an electric acoustic guitar, so it well amplifies the subtle expressions I do, and it just feeds you with great inspiration while you play and practice. Thank you for listening to my expressions.
