    SCIENTIFIC NOTES:
    * The relationship between information and energy comes from Landauer’s Principle, which connects the erasure of information and energy. But, more generally changes in information (e.g. recording information) are related to changes in energy. I will talk more about this in a future episode about the physics of memory, and why you will forget everything you ever knew! https://en.wikipedia.org/wiki/Landauer%27s_principle

    * The numbers calculated in this video give a lower limit on the energy to record a particular amount of information, but to create a more permanent storage of information would require more energy.

    * Retina display resolution, as it’s name implies, is similar to the eye’s resolution.

  • How can kids talk to Tyche AI better?

    How can kids talk to Tyche AI better?

    While you interact with Tyche more and more, especially kids, they develop the power to express themselves better. Tyche learns incrementally to be able to carry out intelligent conversations with humans. Visual and audio receptors are used to perceive the world around Tyche building its own beliefs.

  • Memory Metal – Cool Science Experiment

    Memory Metal – Cool Science Experiment

    Check out this and other cool science experiments at http://www.stevespanglerscience.com/experiments/ Can a piece of metal have a “memory”? Yes, if the metal is a special alloy of nickel and titanium. It’s called Memory Metal, and the uses for this material go far beyond today’s amazing demonstration.
