Theme: Impetus - force that drives change

This event occurred on

London, Kensington and Chelsea
United Kingdom

When we reflect on the last year, many will note that 2020 was a year of transformation. The last 12 months have seen dramatic changes in the world and many others’ personal journeys:

COVID-19 has shaken up our perspectives, way of governance, and reset our world’s vision of what is ‘normal’. Issues related to climate change, racial injustice, and others have also had their moments in the spotlight.

Impetus is a word derived from physics describing momentum, or something that makes a process happen. It is also synonymous with ‘change’.

We believe that ‘Impetus – force that drives change’ provides a fitting theme for this year’s event and cannot wait for you to join us at TEDxImperialCollege 2021.

We have an inspiring line-up of student and external speakers who will focus on personal journeys, innovation, and international activism.
