Explain it like I’m 5 – Susana Cardoso de Freitas

Why are computers getting smaller?
How to read a barcode if it is covered?
How do I find out if the wire has electricity without feeling a shock?
How come there are so many spintronic sensors in a car and I didn’t know?
How spintronic chips can help bacteria detection?

Saturday, 23rd January 2021, at 11:00, Susana Cardoso de Freitas, researcher at Instituto de Engenharia de Sistemas e Computadores para os Microsistemas e Nanotecnologias (INESC MN) and Técnico professor (Department of Physics) will explain us spintronics and how it answers all these questions – and others.

Please send us your questions ahead of time to or join us live on Facebook.

Explain it like I’m 5 – talks at Técnico for children and other curious people of all ages” is designed for young people opening a door to get to know Técnico research and the possibility to ask our scientists a question- even at a distance. Older people can come as well, if the children let them.

On Saturdays, every two weeks, live on Facebook. The talks can be watched later.
