With the invention of the leap year, the Julian calendar was used worldwide for over 1500 years. Over time, it led only to catastrophe.
“We suffer more often in the imagination than in reality.”
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
How we organize all our digital stuff — from work research to side hustles to family photos — is key to our productivity.
The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?
In a state of “hyperwar,” accidents or unexpected AI decisions could lead to widespread devastation before humans could intervene.
Reading between the lines of Dorothy’s adventure to the Emerald City.
Bring not a bagpipe to a man in trouble.
Three fundamental forces matter inside an atom, but gravity is mind-bogglingly weak on those scales. Could extra dimensions explain why?
From hunter-gathers to desk jockeys, we work best when short, intense sessions are followed by lighter fare.
“We are biologically programmed to have empathy. It’s something we can’t suppress.”
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
Some processes, like quantum tunneling, have been shown to occur instantaneously. But the ultimate cosmic speed limit remains unavoidable.
If you have an old TV set with the “rabbit ear” antennae, and you set it to channel 03, that snowy static can reveal the Big Bang itself.
Who’s afraid of utopia? AI doubters have cold feet. History can warm them.
If you said “with the Big Bang,” congratulations: that was our best answer as of ~1979. Here’s what we’ve learned in all the time since.
In July of 2022, the first science images from JWST were unveiled. Two years later, it’s changed our view of the Universe.
Most people have a distorted view of what being a scientist is like. Scientists need to make a greater effort to challenge stereotypes.
Back during the hot Big Bang, it wasn’t just charged particles and photons that were created, but also neutrinos. Where are they now?
Nicole has been dating someone for a while but it’s not working out from her point of view. Is sudden radio silence an ethical option?
The Greeks were among the first to move beyond “primitive money” and establish an official currency, transforming their trade, government, and even philosophy.
Here on Earth, we commonly use terms like weight (in pounds) and mass (in kilograms) as though they’re interchangeable. They’re not.
Cooperation was the first technology.
The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
Who — or what — really controls your mind?
How can you maximize the amount of love and happiness in your life? One of history’s greatest scientists found the answer: with math.
The first personality tests revolved around assessing people’s reactions to ambiguous and often unsettling images. Today, the gold standard is a barrage of questions.
For 550 million years, neutral atoms blocked the light made in stars from traveling freely through the Universe. Here’s how it then changed.
On the largest of cosmic scales, the Universe is expanding. But it isn’t all-or-nothing everywhere, as “collapse” is also part of the story.
