💡Fizika v praksi!

Danes smo tudi mi prisotni na 14. slovenski fizikalni konferenci, kjer se skupaj s slovenskimi fiziki z različnih področij – od temeljnih raziskav do aplikativne znanosti – pogovarjamo o tem, kako lahko temeljna znanost postane uporabna tehnologija.

Na naši stojnici predstavljamo projekte, kjer se fizika sreča z realnim svetom – od medicinskih pospeševalnikov in sistemov za radioterapijo, do fuzijskih reaktorjev in novih kvantnih tehnologij, ki oblikujejo prihodnost znanosti in industrije.

📍 Ustavi se pri nas, spoznaj našo ekipo in odkrij, kako lahko fizika postane tudi tvoja kariera.
