There are many components inside the CPU. The CPU clock keeps the working of the components synchronized. By striking each clock a. Math 5 Project. Alexander Barnett. MP3 Compression. The MP3 is a compressed file format that uses concepts of psychoacoustics and human perception. With math audio lessons True North tells you what components of Mathematics are Download the pdf of the lesson and the mp3 audio file that accompanies it.

Then the circles begin to spin, the big circles swinging the smaller ones around, and the smaller ones spinning faster than big ones.

If you trace the motion of one point on the smallest circle, you can reconstruct a wave of any shape, as shown in the animation and the stills below.

Again, the Fourier transform tells you how to build the wave: which circles, moving at which speeds. Imagine you were talking to your friend over the phone and you wanted to get them to draw this squarish wave. The tedious way to do this would be to read out a long list of numbers that represent the height of the wave at every instant in time.

With all these numbers, your friend could patiently stitch together the original wave. This is essentially how old audio formats like WAV files worked. They can then use this circle picture to reconstruct the original wave.

The Fourier transform shows up nearly everywhere that waves do. An MP3 splits a song into short segments.

The Fourier transform also tells you how much of each note contributes to the song, so you know which ones are essential. This is also how the smartphone app Shazam can recognize a song.


Speech recognition uses the same Fourier-fingerprinting idea to compare the notes in your speech to that of a known list of words. In the old days of Microsoft Paint, images were saved in bitmap BMP files which were a long list of numbers encoding the color of every single pixel.

To build a JPEG, you first chunk your image into tiny squares of 8 by 8 pixels. The result is a huge reduction in file size with only a small reduction in quality, an insight that led to the visual online world that we all love and that eventually gave us cat GIFs.

The response astounded me.

The scientists who responded were using the Fourier transform to study the vibrations of submersible structures interacting with fluids, to try to predict upcoming earthquakes, to identify the ingredients of very distant galaxies, to search for new physics in the heat remnants of the Big Bang, to uncover the structure of proteins from X-ray diffraction patterns, to analyze digital signals for NASA, to study the acoustics of musical instruments, to refine models of the water cycle, to search for pulsars spinning neutron stars , and to understand the structure of molecules using nuclear magnetic resonance.

The Fourier transform has even been used to identify a counterfeit Jackson Pollock painting by deciphering the chemicals in the paint. Aatish Bhatia is a recent physics Ph.

BCS Preliminary Subjects

Mathematically proficient students make sense of quantities and their relationships in problem situations. For example, they can see 5 - 3 x - y 2 as 5 minus a positive number times a square and use that to realize that its value cannot be more than 5 for any real numbers x and y.

Omnivorous — one, who eats everything Linguist — one, who is skilled in foreign languages Photo: Takk by Sigur Ros. Hearse — a vehicle which is used to carry a dead body Related Subjects:
