This document contains a presentation in Vietnamese on the topic of X-rays and their discovery. It includes slides with information about Wilhelm Röntgen, who discovered X-rays in 1896. The document notes that Röntgen took the first X-ray photograph of his wife's hand that same year. It then discusses how X-rays have been used in medicine to allow doctors to see inside the body, as well as other developing applications of the technology over time, establishing X-rays as an important scientific discovery that changed the world.

A photograph that changed the world
This is the first X-ray photograph. It was taken by a German scientist,
Wilhelm Konrad Roentgen, in 1896. It is his wife’s hand. The bones in
her hand (and also her wedding ring!) are clearly seen in the photo.
X-rays were discovered by accident, While Roentgen was
experimenting with electricity. Soon after, he built a first X-ray
machine. Immediately, hospital operations were made much safer.
For the first time, doctors could see inside people’s bodies before
they cut them open! In 1901, Roentgen was awarded a very first
Nobel Prize in Physics. His invention is still used everyday by doctors
and scientists, and is called ‘the window into the human body’.
Since the introduction of computer imaging in the 1970s, X-ray
machines have been used for other things, too. At airports, many
criminals have been caught with illegal items in their luggage. Also,
lost works of art have been discovered underneath other paintings.
In factories, many faults in new products are found every day, using
X-rays. There is no doubt that new uses for X-rays will be developed
in the future.
