Universul nu poate fi schimbat. Repoziționează-te! | Cristian Presură | TEDxBaiaMare

Cristian Presură - "The Universe cannot be changed. Reposition yourself!" How are you doing in physics? The TEDxBaiaMare audience witnessed a lesson that will surely make us relate differently to the smart watches we wear every day. Physicist Cristian Presură is the one who invented the first optical sensor that measures the pulse and we find it in all the smart watches in the world?! He says that the Universe gave him a gift: it gave him the chance to help a lot of people. So, don't forget that strength lies in simplicity! Cristian Presură was born in 1971 in Voineasa and studied at the faculties of electrical engineering and physics. He worked at the Institute of Atomic Physics, where he dealt with electrical installations and studied the properties of lasers with solid active media. In 2002, he obtained his PhD in physics from the University of Groningen, the Netherlands, where he characterized the optical properties of correlated electron systems. His results were published in papers in specialized journals: Physical Review B, Physical Review Letters and Science. He is currently a researcher at Philips, the Netherlands. He specialized in the field of medical sensors. Together with his team, he invented and introduced to the market the first watch capable of measuring the pulse of athletes based solely on optical sensors. He has published dozens of papers and patents. Cristian Presură is actively involved in popularizing science in Romanian, writing articles for newspapers, magazines and television. He is the author of the books Physics told (Humanitas, 2014) and A journey through the universe (Humanitas, 2019). He can be followed weekly with a new video on the YouTube channel "Physics with Cristian Presură". 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
