Pianos can't be perfectly tuned - it's a mathematical fact!

Guaranteed basic income, the concept of no-strings-attached payments to provide people with a financial floor, is being tested in dozens of pilot programs across the country. Stockton, California was one of the first cities to launch a...

There’s this idea that beauty is a powerful guide to truth in the mathematics of physical theory. String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong?

One of the most bizarre proposals for life not as we know it doesn’t even use atoms. It proposes that fundamental kinks and defects in the fabric of the universe - cosmic strings beaded with magnetic monopoles - may evolve into complex...

The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the...

The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general...

Reality has cracks in it. Universe-spanning filaments of ancient Big Bang energy, formed from topological defects in the quantum fields, aka cosmic strings. They have subatomic thickness but prodigious mass and they lash through space at...

Your kitchen really is your own personal science lab, so here are some science-based cooking tricks to make tastier, healthier, and awesomer meals.

Some see string theory as the one great hope for a theory of everything - that it will unite quantum mechanics and gravity and so unify all of physics into one glorious theory.

Your kitchen really is your own personal science lab, so here are some science-based cooking tricks to make tastier, healthier, and awesomer meals.

Physicist Brian Greene explains superstring theory, the idea that minscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is...

Is there any hope for those of us plagued by headphone tangles?

Caroline Phillips cranks out tunes on a seldom-heard folk instrument: the hurdy-gurdy, a.k.a. the wheel fiddle. A searching, Basque melody follows her fun lesson on its unique anatomy and 1,000-year history.

Pianos can't be perfectly tuned - it's a mathematical fact!

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course...

Today we’re going to talk about on how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And...

Stradivarius are synonymous with quality, but how we can replicate their sound is a mystery!

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what's all this nonsense of extra dimensions?

Guitar masters like Jimi Hendrix are capable of bending the physics of waves to their wills, plucking melody from inspiration and vibration. But how do wood, metal, and plastic translate into rhythm, melody, and music? Oscar Fernando...

Music is everywhere, and it is in everything, says musician, student and TeD-ed Clubs star Anika Paulson. Guitar in hand, she plays through the beats of her life in an exploration of how music connects us and makes us what we are.

What is string theory? When string theory is simplified - it can answer the question "Why do we exist?" First you must accept that there are two worlds we live in - the world of the large, the world we can see, which...
