Help us spread the charm of TDA by creating tutorials in a time-boxed way!

Our next tutorial-a-thon is planned for 2023; stay tuned for more details


We aim to create 10 minute videos introducing specific topics from Topological Data Analysis (TDA) to the mathematical community.


You will be assigned to a group of three people, and each person in your group will prepare a short tutorial on their favorite TDA topic!


You will have one week to prepare your tutorial, which you will present to your group in a trial round. You will receive feedback and give feedback on your group mates' tutorials.


A week after, in the next meeting with your group, we would like to ask you to record your tutorial, cut and send it to us together with a title and a short abstract.


Your video will then be published on the AATRN YouTube channel! See for example our Tutorial-a-thon YouTube playlists from Spring 2021 and Fall 2021!

Format of your video

Length: At most 10 minutes

Title: YourTitle [Firstname Lastname]

Only 100 characters are allowed in a YouTube title.

Content tips for your description of the video

  • Write one to five sentences on the main idea of the video. Your description should avoid too much technical detail but should instead invite the interested viewer to watch and learn more.

  • You may include html links in the description (say to a corresponding paper), if you so choose.

  • We will add the sentence This tutorial was contributed as part of the WinCompTop+AATRN Tutorial-a-thon: to the end of each description.

  • The characters “<” and “>” are not allowed in YouTube video descriptions.

Content tips for your video

  • Introduce yourself at the beginning, and then say goodbye at the end :)

  • What is the single main point you are trying to make? 10 minute videos are only long enough to make a single main point.

  • Do you want to share images on your screen or a tablet file that you write on? If so, be judicious with the amount of written text you include -- the more written text you can leave out, the better!

  • The video is not expected to be perfect! If you say a word wrong, just correct yourself (like you would when giving a talk live), don’t try to cut it out or make another take unless absolutely necessary.

Technical tips before recording your video

  • We recommend recording your video over zoom. You can do that with the free zoom licence. However, feel free to record with other programs if you wish to do so, for example OBS.

  • Before recording, make sure that you are in a quiet environment if possible.

  • Upon joining zoom for the recording, change your zoom name to something professional (firstname lastname instead of an email address) in case your name appears in the video recording.

  • Before recording the actual tutorial, make a test run (a few seconds is enough) to make sure your screen is shared correctly, your video is visible (if you want it to be visible), and your voice is well audible.

  • Switch off the sound on your phone and possibly the sound on your computer or use headphones to prevent the notification sounds from incoming messages, emails etc. from disturbing your tutorial. Alternatively, mute all notifications.

  • If you plan to switch between screens during the recording, make sure that no private files on your desktop/background are visible while you switch.

Technical tips while recording your video

  • Record to the zoom cloud (not locally) since that seems to make a better video. (However, if you have a bad internet connection you might want to consider recording locally.)

  • Have all audience members mute themselves and turn off their videos.

  • Leave 5 seconds of blank space before and after your tutorial (while looking at the camera and smiling) to make cutting easy.

  • We advise your group members in the audience to not ask questions until the end of the tutorial. It is up to you and your group to decide whether to include questions in the recording. If you would like audience questions from your group members, you can end by saying “What questions do you have? Thanks, bye!” If not, you can end by saying “Thanks, bye!”. Question periods that take you a few minutes over the 10 minute limit are fine. [Of course, off-the-record questions after the person leading the tutorial has said goodbye are fine.]

Technical tips after recording your video

  • If you recorded your video to the zoom cloud, the owner of the zoom link can find it by signing into and clicking on ‘my account’, and then on ‘recordings’. Keep in mind that the recording will only be available after the meeting is ended (and after some processing time). The owner of the zoom link can then email you the link to the recording by clicking ‘share…’ and then ‘copy sharing information’.

  • Cut the video at the beginning and at the end, but don’t do any other video editing. You could use a MAC’s pre-installed QuickTime Player, or Windows’s software Photos for the trimming. If you don’t have software installed you can use a website for trimming, like

After your tutorial is uploaded

After your tutorial is uploaded to YouTube we suggest you to put a thumbs up to your video. That way you will get notified whenever someone likes or comments on your tutorial.

It might happen that you spot a mistake in your tutorial after it has been uploaded to YouTube. If this is the case, we recommend leaving a comment on YouTube under the video. We are also happy to alter the description of the video to inform the viewers about the mistake. If you wish us to do so please drop us a mail.

We will remove your tutorial from the channel upon your request. However, we do not recommend you to take your video offline, re-record it, and upload it again if there are only a few minor mistakes in your tutorial.

If you spot a mistake in other people's tutorials, please leave a comment under their video.

We reserve the right to remove videos if we find them inappropriate.


When you have your tutorial ready, you can share it with us by filling the upload form where you submit the title and the description of your tutorial, and a link to your recording.

We encourage you to use the service WeTransfer to generate the link to your recording, since the process is easy and supports the upload of files up to 2GB.

How to use WeTransfer to generate a link to your recording

  1. Click on the link to get to the main page of WeTransfer.

  2. You may be asked to sign up. In this case, click on ‘No thanks’. You do not need an account to use the service!

  3. You can upload your file in the window on the left.

  4. WeTransfer has two options to send files. The default option is to ‘send an email transfer’. You need to change this to ‘Get transfer link’. In order to do so, click on the three dots on the lower left corner of the window and select ‘Get transfer link’. Then click on the ‘Get link’ button.

  5. After the link is generated click on the ‘Copy link’ button and paste the link into the Google form.
