Tessa Parker explores the beauty and frustration of the unknown, from the mystery of consciousness to the vastness of infinity. She reflects on how questions without answers can cause anxiety, but also fuel endless curiosity. Drawing from science, philosophy, and personal experience, Tessa makes a case for embracing uncertainty as a catalyst for growth. In a world full of unknowables, the pursuit of knowledge itself is what keeps us moving forward. Currently studying neurobiology at UCI (on exchange) as a recipient of the Fulbright Killam fellowship, she's interested in all things to do with the brain and health policy. Back home in Toronto, she is the president of her school's Pre-Medical society and in 2023, revived a non-profit in her hometown of Edmonton, which serves and connects with the homeless community on Sunday evenings every week. She hopes to pursue an MD-PhD, advocating for free and accessible healthcare along the way. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
