    I love this. I am thinking if I can memorize an entire binary code of a recording I could have that recording in my head and just have to input it into a computer lol.

    Awesome, crystal.clear and concise. I really found useful the second example, where you go strait and perform filtering operation. In many cases an inner ou nested query would have been used to solve that one but I persornally find it hard to read subqueries under the where clause. Thank you for the insightful tutorial.

    "The answers to a multiple choice question" is Qualitative. The order of the choices doesn't matter. Also, they could have been "option 'sky'", "option 'earth'" instead of "option 1" and "option 2", where the fact that they are numbers in the last case is just circumstantial.

    Frequencies below and above we feel them with other natural ways - You know that we have more than ears to feel above and below frequencies - colours are frequencies smell also and all around us are waves/frequencies. Digital for now can not show the reality of analogue sounds and colours or other waves/frequencies many are missing - our bodies and nature around us have gazillions frequencies we don't "listen" all with our ears.
