“To be ignorant of causes is to be frustrated in action.” So wrote Francis Bacon, counsel to Queen Elizabeth I of England and key architect of the scientific method. In […]
In his new book, “The Wires of War: Technology and the Global Struggle for Power,” Jacob Helberg outlines the brewing cyberwar between Western democracies and autocracies like China and Russia.
More than any other of Einstein’s equations, E = mc² is the most recognizable to people. But what does it all mean?
The solar system has some strange stuff in it. Learning how it ended up that way can tell us where we’re going.
When maps meet stamps, you get a love child called “cartophilately.”
Time for a status check before watching “Moon Knight.”
Humans who’ve lived through the same events often remember them differently. Could quantum physics be responsible?
A thought experiment from 1867 leads scientists to design a groundbreaking information engine.
Your bites will heal, but will you ever sleep well again after an infestation of bloodsucking parasites?
Probability, lacking solid theoretical foundations and burdened with paradoxes, was jokingly called the “theory of misfortune.”
From mobile learning to microlearning, these five methods for training employees are some of the most effective in the modern world of business.
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.
A new bridge joins a divided Croatia, but it cuts Bosnia out of Europe — literally and figuratively. A bridge meant to unite also divides.
It had long seemed impossible that supermassive black holes could grow to such enormous sizes. But the biggest problem is now solved.
In 1974, Hawking showed that black holes aren’t stable, but emit radiation and decay. Nearly 50 years later, it isn’t just for black holes.
And why you, a non-expert, should absolutely not consider “explaining what you know” to an actual expert in the field.
The puzzle of play
The purpose of play — for children, monkeys, rats or meerkats — has proved surprisingly hard to pin down. Scientists continue to toss around ideas.
NASA will use energy from Earth’s gravity to launch the Lucy spacecraft in October of this year.
In a major advance, scientists have found a new and groundbreaking way to force electrons to flow only in one direction in a superconductor.
Psychologists often view relationship power imbalances through three unique dynamics.
The design of a classic video game yields insights on how to address global poverty.
Mathematically, it is a monster, but we can understand it in plain English.
In special relativity, the statement that two events happened at the same time is meaningless.
Leap years will only get us through the next few thousand years before we have to fix it. With every year that passes, we assume that two separate things will both […]
By studying the oldest animals, researchers hope to pinpoint factors affecting human longevity.
American students are being compelled to specialize earlier and earlier. Here’s what it takes to build a successful physics foundation.
The study identified superhabitable planets outside of our solar system.
