What word were you thinking of?

Our brain has the astonishing capability to fill in missing words in a ________. It sees context, compares it with its database of memories and picks what fits the most. Because we all have different sets of memories, we don’t all get the same answer. Think of human knowledge as a puzzle and problem-solving as putting its pieces together. Naturally, you start with what is in your local field of view. The underestimated next step is finding what is not.

Without looking beyond our own horizon, it’s not possible to realize how our individual knowledge connects to other information, currently out of reach. Without putting it in context, it’s like trying to solve a puzzle without knowing what the picture looks like. Like only using the back where all the pieces are gray.

Join us at TEDxTUM 2022 and get inspired by our speakers, showcasing their parts of the puzzle, because it might just be the blank that you’ve been missing to get a glimpse at the bigger _______.

Claudia Traidl-Hoffmann

Medical Doctor Aiming at Preventing Diseases
Practicing dermatologist, ski-ing instructor, singer, musician, author, wife and mother of two, calling Claudia Traidl-Hoffmann “multifaceted” is an understatement. Driven by a strong sense of empathy she hopes to literally “heal the world” by preventing diseases altogether. As a physician-scientist, her research in medical science focuses on the interaction between humans and the environment around them which then determines the state of health or illness in a person. To this end, Claudia and her team were able to revolutionize the idea of how allergies arise and found new drivers for allergic immune responses in pollen. Apart from this, Claudia hopes to educate the world about climate change and how it impacts each and every one of us. Through her book, Überhitzt, she tackles the topic and goes on to explain how climate change impacts our health and what we can potentially do about it before it is too late. She is convinced that she has what it takes to drive this change!

Doro Seror

Environmental Artist
“Everyday is a new beginning” that is what Doro Seror encapsulates in both herself and her art. As an environmental artist, she mainly focuses on sustainability and recycling in her artistic work to bring forth new creations through a constant renewal process. Seror studied at the Academy of Fine Arts in Munich, in addition to later exploring and learning dance, body therapy and shamanism. Seror has had notable exhibits at the Pinakothek der Moderne in Munich and the Ulster Museum in Belfast. Seror draws from her diverse experience and background describing her artworks as rituals and ceremonies that support people on their journey. She places utmost importance to create art that defies the very meaning of the word and to not waste the resources of our planet. Seror has created installments from surplus of used clothing to demonstrate the impact of unnecessary clothing waste and to teach people ways to actively participate in art and sustainability in their own lives.


Musician, Singer & Composer
HerTree (Alexandra) is a musician, composer and singer. Manifesting a novel and fascinating approach to music, she introduces the idea of producing music only with nature recordings. Growing up close to forests as a child, she started observing the enchanting melodies it can produce from a small age, leading her to record audio while she was hiking, just so that she could hear them again. Ranging from Bavarian forests to jungles in Thailand, Alexandra records in different environments due to her appreciation of the vast differences between the sounds each produces. As she released her first songs in 2019, she won a cultural award and was, after the release of her debut album in 2021, featured prominently on German television and radio stations. Currently, she’s working on new songs, looking to bring the sounds of the rainforest to her listeners next.

Over time, they expanded it to turn into one of the most seminal resources for sexual well-being and happiness.

With determination, ease, and euphoria they frame a healthy discussion around sex and all topics that can bring color into your bedroom.
