The Infinite Hotel Paradox - Jeff Dekofsky | TED-Ed - 0 views

  •  
    The Infinite Hotel, a thought experiment created by German mathematician David Hilbert, is a hotel with an infinite number of rooms. Easy to comprehend, right? Wrong. What if it's completely booked but one person wants to check in? What about 40? Or an infinitely full bus of people? Jeff Dekofsky solves these heady lodging issues using Hilbert's paradox.

Population pyramids: Powerful predictors of the future - Kim Preshoff | TED-Ed - 0 views

  •  
    Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples.

The origin of countless conspiracy theories - PatrickJMT | TED-Ed - 0 views

  •  
    Why can we find geometric shapes in the night sky? How can we know that at least two people in London have exactly the same number of hairs on their head? And why can patterns be found in just about any text - even Vanilla Ice lyrics? PatrickJMT describes the Ramsey theory, which states that given enough elements in a set or structure, some interesting pattern among them is guaranteed to emerge.

How to visualize one part per million - Kim Preshoff + The TED-Ed Community | TED-Ed - 0 views

  •  
    "Parts per million" is a scientific unit of measurement that counts the number of units of one substance per one million units of another. But because it's hard to conceptualize really large numbers, it can be difficult to wrap our brains around what "one part per million" really means. Kim Preshoff (with help from 100+ animators from the TED-Ed Community) shares nine helpful ways to visualize it.
