In some blog article earlier, I had claimed that we can see, taste, touch, smell, and hear mathematics every where around us! Well, to be precise, I had explained that ‘sweetness’ or ‘sourness’ of what we eat or drink can be measured with the pH value, which uses the tool of common logarithms !

Now, we all love mp3 music. It uses a special algorithm to measure the sensitivity of the human ear to various frequencies and intensities. It masks out certain pieces of the sound or music signal (called information signal, in the language of engineering) and thus achieves “compression” of the music signal. So, the creators of the mp3 algorithm actually created a mathematical model of the human ear.

And, of course, the loudness of sound is measured in terms of decibels, which is again a logarithmic quantity.

Architects use “golden ratio” to create a majestic structure that we can see/marvel at. This golden ratio is a special number.

The pain that human skin/body feels is measured in terms of “bols”. ( Go ahead and google this term).

And, of course, smell, obnoxious or aromatic, is measured in terms of the concentration of special molecules in the immediate vicinity.

Nature also loves math! Do you know that the spirals of a daisy flower are arranged like Fibonacci numbers/sequences?

More on each of these topics later,
