How a disgruntled scientist looking to prove his food wasn’t fresh discovered radioactive tracers and won a Nobel Prize 80 years ago

Some Nobel Prize-winning ideas originate in strange places, but still go on to revolutionize the scientific field. George de Hevesy’s research on radioactive tracers is one such example.

Superconductivity at room temperature remains elusive a century after a Nobel went to the scientist who demonstrated it below -450 degrees Fahrenheit

Superconductivity may sound like science fiction, but the first experiments to achieve it were conducted over a century ago. Heike Kamerlingh Onnes, credited with the discovery, won a Nobel Prize in 1913.

Why Einstein must be wrong: In search of the theory of gravity

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.

3 reasons we use graphic novels to teach math and physics

Graphic novels pair text and images to explain complex topics – from thermodynamics to abstract math – without alienating STEM-averse students.

Researchers dig deep underground in hopes of finally observing dark matter

To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.
