Mathematicians Have Developed a Computing Problem That AI Can Never Solve

Not everything is knowable. In a world where it seems like artificial intelligence and machine learning can figure out just about anything,

A short note on how to interpret Fourier Series animations

When one searches for Fourier series animations online, these amazing gifs are what they stumble upon.

They are absolutely remarkable to look at. But what are the circles actually doing here?

Vector Addition

Your objective is to represent a square wave by combining many sine waves. As you know, the trajectory traced by a particle moving along a circle is a sinusoid:

This kind of looks like a square wave but we can do better by adding another harmonic.

We note that the position of the particle in the two harmonics can be represented as a vector that constantly changes with time like so:

And being vector quantities, instead of representing them separately, we can add them by the rules of vector addition and represent them a single entity i.e:

                                                  Source

The trajectory traced by the resultant of these vectors gives us our waveform. 

And as promised by the Fourier series, adding in more and more harmonics reduces the error in the waveform obtained.

        Have a good one!

CSI Cameras on the TX2 (The Easy Way) - Peter Moran's Blog

I love Nvidia’s new embedded computers. The Nvidia Jetson embedded computing product line, including the TK1, TX1, and TX2, are a series of small computers made to smoothly run software for computer vision, neural networks, and artificial intelligence without using tons of energy. Better yet, their developer kits can be used as excellent single board … Continue reading CSI Cameras on the TX2 (The Easy Way) →
