    When did the News Start?

    Let’s face it: we all have news cycle fatigue. If it’s not struggling to find reliable sources online, then it’s figuring out how to sift through the myriad of competing (and sometimes conflicting) headlines that roll across our TV screens, cell phones and social media accounts. But when did the news, in all of these varied and sundry forms, become integral to our lives? And why do we even follow it? Survival? Desire to help and empathize? Staying informed? Entertainment? Our answers will vary from story to story, but one thing is certain. We live in a culture in which the news has become almost impossible to ignore. Today I’m…

    Fact vs. Theory vs. Hypothesis vs. Law… EXPLAINED!

    [MUSIC] We need to get something straight. Evolution by natural selection is a theory. So is climate change. But people keep saying that like it’s a bad thing… [MUSIC] I get it, I understand your frustration. We’re all searching for ultimate hashtag #truth, and complex, challenging ideas don’t always fit nice and neatly in our brains. But what is truth? Are there different levels of truth? Are some truths truthier than others? I don’t know. But I do know this: Science is the absolute best tool we have for understanding how the universe works, and theory is not a 4-letter word. If we’re going to trust science together, the least…

    Solving the Impossible in Quantum Field Theory | Space Time

    [MUSIC PLAYING] HOST: This episode is supported by Curiosity Stream. Quantum field theory is stunningly successful at describing the smallest scales of reality, but its equations are also stunningly complex. A lot of the genius in QFT’s development was in finding brilliant hacks to make these equations workable. The most famous of these are the incredible Feynman diagrams. [MUSIC PLAYING] The equations of quantum field theory allow us to calculate the behavior of subatomic particles by expressing them as vibrations in quantum fields. But even the most elegant and complete formulations of quantum field theory, like the Dirac equation or Feynman’s path integral, become impossibly complicated when we try to…

    Self-Replicating Robots and Galactic Domination | Space Time | PBS Digital Studios

    [MUSIC PLAYING] This episode is supported by the Great Courses Plus. Space is big, maybe even too big to be easily colonized by real, living aliens. But what about almost-living machines? I mean spacecraft capable of replicating themselves and exponentially spreading across the galaxy. I’m talking about Von Neumann probes. Our galaxy is depressingly natural looking. Stars for the most part act very star-like, their brightnesses and colors slavishly following the equations of stellar physics. Space stuff gravitates around in slow, stately arcs that would make Newton proud. Even the unusual denizens of the galaxy like pulsars and black holes just do what they do. And Nature rules the sky.…

    Will You Still Eat Raw Fish After Watching This Video?

    Hey smart people, Joe here. What do poke, sushi and sashimi, and all these dishes have in common? They’re delicious. They’re made with raw fish. And they could all give you parasites. Yep. The ocean is a parasite playground. That warning about raw or undercooked fish at the bottom of every menu? It’s there for a reason. At least 15,000 different species of wormy parasites use fish as a host. Raw fish dishes like sashimi are, well… raw. They’re never cooked–which means any parasites or parasite eggs in the fish can end up in our tummies. In case you’re wondering, let me make this next part extra clear for ya:…

    Is Minecraft the Ultimate Educational Tool? | Idea Channel | PBS Digital Studios

    Here’s an idea– Minecraft is the ultimate educational tool. You guys remember Minecraft. We made this other video about it that one time where we talked about how it’s basically going to save us all. But in case you need a refresher, Minecraft is a computer game that can best be described as first person Legos with a dash of husbandry, a heaping helping of architecture, and a pinch of slay the dragon. In Survival Mode you have to gather resources and materials and fight the bad guys, some of whom are very sneaky. [HISS] In Creative Mode, you get to– ready for Nicholas Cage– go nuts. The pixelated sky…

    The Quantum Experiment that Broke Reality | Space Time | PBS Digital Studios

    [MUSIC PLAYING] MATTHEW O’DOWD: This episode is supported by The Great Courses Plus. One of the strangest experimental results ever observed has got to be that of the single particle double-slit experiment. It’s one of the most stunning illustrations of how the quantum world is very, very different from the large-scale world of our physical intuition. In fact, it hints that the fundamental nature of reality may not be physical at all, at least in any sense that we’re familiar with. [THEME MUSIC] Let’s start with the familiar. In fact, let’s start with a rubber duckie. It bobs up and down in a pool, causing periodic ripples to spread out.…

    Is Math a Feature of the Universe or a Feature of Human Creation? | Idea Channel | PBS

    Here’s an idea. Math might not actually exist. [MUSIC PLAYING] Love it or hate it, you can’t argue the importance of math. Math, as a system, is elegant, exhaustive, and frequently even beautiful. In the words of Eugene Wigner, it is, quote, “Unreasonably effective when put to use in all other sciences.” But in light of its beauty and effectiveness, and in spite of its importance, there is nothing you can argue about it. You could argue where it comes. Where biology is the study of living organisms, physics the study of the universe and its forces, chemistry the study of chemicals, math is the study of math. Unlike all…
