What did I need to do in childhood to win the support and approval of my parents?

We might - to sharpen the picture - need to lean on a few subsidiary enquiries:

To please my mother, I needed to…

Not to upset my mother, I needed to…
Not to upset my father, I needed to…

It’s 4am, and the big test is in 8 hours. You’ve been studying for days, but you still don’t feel ready. Should you drink another cup of coffee and spend the next few hours cramming? Or should you go to sleep? Shai Marcu defends the latter option, showing how sleep restructures your brain in a way that’s crucial for how our memory works.

How does ballet convey narrative, emotion, and character? Dive into “The Sleeping Beauty” to see how a ballet creates its essential elements.

--

A baby cursed at birth. A fierce battle of good and evil. A true love awoken with a kiss. Since premiering in 1890, “The Sleeping Beauty” has become one of the most frequently staged ballets in history. So what makes this piece so beloved? And what exactly does ballet bring to this— or any other— story? Ming Luke shares what makes ballet the perfect medium for stories old and new.

Dig into the science of stretching, and find out what it actually does to your muscles and how you can improve your flexibility.

--

An athlete is preparing for a game. They’ve put on their gear and done their warmup, and now it’s time for one more routine — stretching. Typically, athletes stretch before physical activity to avoid injuries like strains and tears. But does stretching actually prevent these issues? And if so, how long do the benefits of stretching last? Malachy McHugh explores the finer points of flexibility.

In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around ... thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move.
