Sauropods that tower above treetops and tyrannosaurs that make the Earth tremble beneath their weighty footsteps are two iconic dinosaur images. These prehistoric giants have fascinated us for centuries, igniting our imagination and curiosity about the world that existed long before we set foot on this planet. Among the myriad of questions that arise when we ponder these magnificent creatures, two stand out. Why were some dinosaurs so big? How did their environment play a role in their size? ...read more
Physicists have long studied soap bubbles for their extraordinary geometric properties as minimal surfaces, for the way they oscillate and for the beautiful interference patterns that appear on their surfaces.So it would be easy to think that soap bubbles have little more to give in terms of exotic physics and no new applications beyond the bathtub. But that would be wrong. Enter Zala Potŏcnik and Matjaž Humar at the University of Ljubljana in Slovenia, who have found a way to turn soap bubble ...read more
Causality is kind of important.Causality — the concept that causes always come before effects — forms the bedrock for our physical understanding of the universe. It isn’t just a theory or law of physics. Causality is physics.Therefore, we assume causality to be true every time we construct a new theory or develop a new model. And we always bake it into each of our equations, automatically constructing models where (you guessed it) causes lead into effects.But causality doesn’t just form ...read more
Perhaps no name is more recognizable in connection with The Manhattan Project than Robert Oppenheimer. Oppenheimer, a genius theoretical physicist, was the director of the Los Alamos Lab, where the first atomic bomb was developed. (Credit:Jeffrey M.

His breadth of knowledge exceeded the realm of physics and included history, the arts, language and ...read more
If you’ve heard Michael Jackson’s familiar refrain “Annie, are you OK?,” you know one of the first steps of performing CPR: assessing whether the other person is responsive. And that’s not a coincidence. It’s said that this particular lyric was directly inspired by Resusci Anne — the name given to the anatomical manikin found in first aid classes around the world. And she’s far more than just a pretty face.Receiving cardiopulmonary resuscitation, or CPR, can double or triple the ...read more
