Tanulmányi hírek

Honlap_borito

Érdekel a körülötted lévő világ, és megismernéd pontosabban hogyan is működik? Szeretnél az ország egyik legjobb egyetemén egy gyönyörű városban tanulni? Ha a válaszod igen, legyél Te is fizika, fizikus-mérnök, csillagász, fotonikai mérnöki vagy fizikatanár szakos hallgató az SZTE-n!

Uj_fejlecek_honlapra

A 2024/2025-ös tanévben indult el az SZTE Fizikai Intézet új képzése, a fizikus-mérnöki BSc. Az ipari partnerek igényeire szabott, gyakorlatorientált képzés első tanéve 9 hallgatóval indult el. Hallgatóink immár túl vannak az első félévükön, így megkérdeztük őket, milyen tapasztalatokat szereztek eddig a képzésről, az oktatókról és az egyetemi közösségről.

Nagy_Csongor_cikk_002

Nagy Csongor harmadéves fizikushallgatónk, az ELI ALPS Lézeres Kutatóintézet gyakornoka az Országos Tudományos Diákköri Konferencia (OTDK) Optika és Lézerfizika Tagozatán Felületi plazmonok időbontott ellipszometriai vizsgálata című dolgozatával harmadik helyezést ért el. Csongor a fizikához vezető különleges útjáról adott interjút az ELI ALPS-nak.

Fejlec_SZTE_FI_13

Gilinger Tibor kétszeres OTDK és TDK résztvevő, másodéves kora óta a TeWaTi kutatócsoport tagja, PhD-hallgató, a lézeres kutatások ígéretes alakja. A fiatal kutató 2. helyezést ért el a 37. OTDK Fizika, Földtudományok és Matematika Szekciójában, ennek apropóján a nagy intenzitású lézerekhez kötő kutatási témájáról, a kutatócsoportban végzett munkájáról, tudományos pályájának eddigi állomásairól, valamint az OTDK-n szerzett tapasztalatairól kérdeztük. Tibor kiváló példakép lehet mindazok számára, akik már hallgatóként belevágnának a kutatásba és elmélyednének a fizika különleges világában.
