All Stories by Katie Grace Carpenter
- Space
Scientists Say: Cosmic rays
These energy-packed particles come to us from the farthest reaches of outer space.
- Math
Scientists Say: Fractal
There’s no end in sight for these infinitely complex geometric wonders.
- Science & Society
Scientists Say: Thought experiment
Thinking through imaginary, sometimes absurd, scenarios can catalyze new ways of thinking.
- Materials Science
Scientists Say: Superconductor
At cold enough temperatures, these materials can conduct electricity with no resistance.
- Chemistry
Scientists Say: Excitation
Excited electrons are to thank for dazzling fireworks displays, plants harnessing energy, the semiconductors behind modern tech and more.
- Chemistry
Scientists Say: Methane
Used to cook food and heat homes, this potent greenhouse gas accounts for 30 percent of the warming of our climate.
- Math
Scientists Say: Correlation and Causation
There is a correlation between countries where people eat more chocolate and those that produce more Nobel Prize winners. But beware assuming that one variable causes the other.
- Materials Science
Scientists Say: Semiconductor
Modern electronics, from cell phones to video games, work thanks to these conductor-insulator hybrids.
- Earth
Scientists Say: Supercontinent
These gigantic landmasses form when much of Earth’s landmass smashes together.
- Tech
Scientists Say: Bionic
This type of technology combines natural and synthetic systems. It can restore lost vision and mobility and even grant cells new abilities.
- Environment
Scientists Say: Carbon capture
Carbon capture technology tackles climate change by stomping out carbon dioxide at the source.
- Science & Society
Scientists Say: Model
Models are representations of real-life systems or processes that we use to ask questions, make predictions and test our knowledge.
