College football is back, so Hilton called in me, the superstition concierge, to make your fan rituals a reality. Need a room to match your lucky number? We got you. Want to make sure our team doesn't wash your lucky jersey? Ooh, that smells lucky. Hilton's unmatched hospitality can keep up with any superstition. Even a marching band wake-up call at 555 in 55 seconds. Hit it! When you need a team that will do whatever it takes on game day, it matters where you stay. Hilton, for the stay.

How do you know you're real? It's an obvious question until you try to answer it, but let's take it seriously. How do you really know you exist? In his meditations on first philosophy, René Descartes tried to answer that very question, demolishing all his preconceived notions and opinions to begin again from the foundations. All his knowledge had come from his sensory perceptions of the world. Same as you, right? You know you're watching this video with your eyes, hearing it with your ears. Your senses show you the world as it is. They aren't deceiving you. But sometimes they do. You might mistake a person far away for someone else. Or you're sure you're about to catch a fly ball, and it hits the ground in front of you. But come on, right here and now, you know what's right in front of you is real. Your eyes, your hands, your body, that's you. Only crazy people would deny that, and you know you're not crazy. Anyone who'd doubt that must be dreaming. Oh no, what if you're dreaming? Dreams feel real. You can believe you're swimming, flying, or fighting off monsters with your bare hands when your real body is lying in bed. No, no, no. When you're awake, you know you're awake. Ah, but when you aren't, you don't know you aren't. So you can't prove you aren't dreaming. Maybe the body you perceive yourself to have isn't really there. Maybe all of reality, even its abstract concepts like time, shape, color, and number, are false, all just deceptions concocted by an evil genius. No, seriously. Descartes asks if you can disprove the idea that an evil genius demon has tricked you into believing reality is real. Perhaps this diabolical deceiver has duped you. The world, your perceptions of it, your very body, you can't disprove that they're all just made up. And how could you exist without them? You couldn't, so you don't. Life is but a dream, and I bet you aren't row, row, rowing the boat merrily at all, are you? No, you're rowing it wearily, like the duped, non-existent doof you are, slash aren't. Do you find that convincing? Are you persuaded? If you aren't, good. If you are, even better. Because by being persuaded, you

How do you know you’re real? Is existence all just a big dream? Has some mad scientist duped us into simply believing that we exist? James Zucker investigates all of these questions (and more) in this mind-boggling tribute to René Descartes’s "Meditations on First Philosophy."
