I was another 19th century German chemist. I pioneered the fields of emission spectroscopy and photochemistry, and I also co-discovered two elements, cesium and rubidium. Despite these accomplishments, I'm best remembered for my nifty little burner, which made much of my work possible. Who am I?

  1. Robert Bunsen

  2. Friedrich Woehler

  3. Gustav Kirchhoff

  4. George Burns

A Correct answer
Explanation

Robert Bunsen was a 19th-century German chemist who co-discovered cesium and rubidium, pioneered emission spectroscopy and photochemistry, and invented the Bunsen burner. The burner, which produces a nearly non-luminous flame, was crucial for his spectroscopy work and remains a standard laboratory tool today.

I was also a 19th century chemist, but French this time. My accomplishments are so many that they are hard to list: I developed vaccination, discovered the germ theory of disease, proposed the existence of viruses, invented stereochemistry... Today, you can see my name on almost any milk carton. Who am I?

  1. Jean-Pierre Homogen

  2. Jonas Salk

  3. Edward Jenner

  4. Louis Pasteur

D Correct answer
Explanation

Louis Pasteur developed the germ theory of disease, created vaccines (including for rabies and anthrax), proposed the existence of viruses, invented stereochemistry, and his pasteurization process is used to make milk safe - hence his name appearing on milk cartons as 'pasteurized'.

Multiple choice general knowledge science & technology

I was a 19th century German mathematician and astronomer. I developed a lot of math: there's my configuration, formed by two mutually inscribed tetrahedra, my transformation in number theory, my transformations in projective geometry, my function, and my inversion formula. Pretty nifty, eh? You're probably most familiar with the strip named after me, a two-dimensional surface with only one side. Who am I?

  1. Felix Klein

  2. August Ferdinand Möbius

  3. David Hilbert

  4. Henri Poincaré

D Correct answer
Explanation

Robert Jemison Van de Graaff invented the Van de Graaff generator in 1929, an electrostatic generator that can produce high voltages used in particle accelerators. While mostly replaced by more powerful devices, it remains popular for educational demonstrations because it safely shows static electricity principles.
