Why do art historians use X-rays to analyze historical paintings?

Pick one

or
A: To reveal hidden layers and older sketches underneath

X-rays can pass through newer layers of paint to reveal sketch outlines, alterations, or entirely different paintings hidden beneath. This helps museum experts detect clever forgeries and study the artist's original process.

During World War I, what did Marie Curie develop to help battlefield surgeons locate shrapnel in wounded soldiers?

Pick one

or
A: Mobile X-ray vehicles

Marie Curie created mobile units equipped with X-ray machines and darkroom gear, known as 'Little Curies'. She personally drove these to the front lines and trained women to assist in diagnosing battlefield injuries.

In the mid-20th century Soviet Union, what illegal items were secretly pressed onto discarded X-ray films?

Pick one

or
B: Banned Western music

Known as 'bone music' or 'ribs', bootleggers used discarded hospital X-ray sheets to press banned Western jazz and rock music. The flexible sheets were cheap, available, and easy to cut into circles and hide.

What was the subject of the very first medical X-ray image taken by Wilhelm Röntgen in 1895?

Pick one

or
B: His wife's hand

Wilhelm Röntgen captured the first medical X-ray of his wife Anna Bertha's hand. Upon seeing her bones and wedding ring, she famously exclaimed, 'I have seen my death!' This historic image marked the beginning of diagnostic radiology.

Whose X-ray diffraction image, known as 'Photo 51', was crucial in determining the double-helix structure of DNA?

Pick one

or
B: Rosalind Franklin

Photo 51 was captured by chemist Rosalind Franklin and her student Raymond Gosling in 1952. This critical image revealed the helical structure of DNA, which helped Watson and Crick build their famous double-helix model.

For his discovery of X-rays, Wilhelm Röntgen received the very first Nobel Prize in Physics in which year?

Pick one

or
A: 1901

Röntgen was awarded the inaugural Nobel Prize in Physics in 1901. Generously, he donated his prize money to his university and refused to patent his discovery, believing that his work should belong to everyone.

Which specialized type of low-dose X-ray scan is the standard method for measuring bone mineral density?

Pick one

or
A: DEXA scan

Dual-energy X-ray absorptiometry, or DEXA, uses two different X-ray beams to measure bone density. It is highly effective for diagnosing osteoporosis and predicting fracture risks with minimal radiation exposure.

What was the first cosmic X-ray source discovered outside our solar system?

Pick one

or
A: Scorpius X-1

Scorpius X-1, located about 9,000 light-years away, was detected in 1962. It is a binary system where a neutron star pulls matter from a companion star, heating it up so much that it releases intense X-rays.

Which scientist won a Nobel Prize for using X-ray crystallography to determine the molecular structure of penicillin?

Pick one

or
B: Dorothy Hodgkin

Dorothy Hodgkin solved the structure of penicillin in 1945 and later vitamin B12, earning her the Nobel Prize in Chemistry in 1964. Her work revolutionized the study of complex biological molecules and helped mass-produce medicine.

What does the 'X' in the term 'X-ray' originally stand for, as named by its discoverer Wilhelm Röntgen?

Pick one

or
A: An unknown type of radiation

Röntgen used the mathematical symbol 'X' because the nature of these rays was completely unknown to him at the time of his discovery. Even though scientists later understood what they were, the mysterious name stuck around.
