    _"I want to make one minor quibble about the idea that there's Mathematics behind anything, there is no math behind anything math is one of the languages that we use to describe the world, computational languages are also languages that we use to describe the world"_ .
    _Allen Downey_
    This is the best thing I've heard in my scientific life. Thank you Mr. Downey.

      Unless we live in a simulation, then math IS behind everything.

    it's not just the technical aspects of the talk, but rather the motivation behind why Allen is doing it (first 1min of talk) and his enthusiasm that impressed me. we need more teachers like him

    You could probably use that room acoustic transfer in video games quiet effectively. having the same set of base sounds, and then layering on the environment would be a pretty nice system that wouldn't require too much work

    Given a flute music file, how can we convert the music to notes and decompress the file back to audio blocks using literally any method( trained spectograms, any ML algorithm..)

    We are implementing the Mamuni project in Kenya and eventually in India and other countries enabling unsophisticated users to make a local phone call on an inexpensive mobile phone and speak any of the indigenous languages of Kenya and listen to Mamuni guide them through steps to enable messaging and a variety of additional Internet-like applications. We need to be able to process single-word user input and compare it to a small number of words recorded by a native speaker of the indigenous language in which the user is speaking. Would you or someone you know be interested in helping us address this issue? Looking forward to hearing from you.

    If you change the interval of the red alert signal and make a second one with e^-t frequency dependence, and then splice them together, you'll get the Siren sound from Kill Bill.

      Not only is it a possibility, but it is a inevitability. Analyzing a continuous environment using discrete particles rather than a continuum is a silly constrain due to lack of ingenuity in fluids education. In the next 10-15 years we will be transitioning from using finitebody simulations to fft based simulations which will both be less computationally expensive, along with being more accurate.
