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.
