about the x-ray part : in 1897 it was the Greco-Turkish war not the Balkan war mam. The Balkan wars were fought in 1912 and 1913. Kindly pay attention to your facts cause it isn't the first time.
Thanks

FYI, X-rays were first discovered in late 1895 as mentioned in the video and they have been used since then in the Greco-Turkish, Russo-Japanese and Balkan wars. All facts stated in the video are correct.
