Pataphysica D: Filtering with differential equations
http://ristoid.blogspot.com/2013/05/filtering-with-differential-equations.html
Nonlinear twists of the imagination. Thursday, May 2, 2013. Filtering with differential equations. For those of us who are more familiar with digital filters than their analog counterparts, a one pole lowpass filter is easy:. But how do you filter a signal with an ordinary differential equation? Working backwards, we should have an ODE that says. For some suitable constants A. Yet to be found. The differential may be approximated with a forward difference over a short time interval T. 8776; ( y.

Pataphysica D: Golomb Rulers and Ugly Music
http://ristoid.blogspot.com/2015/08/golomb-rulers-and-ugly-music.html
Nonlinear twists of the imagination. Wednesday, August 12, 2015. Golomb Rulers and Ugly Music. Each distance from 1 to 6 can be found between pairs of marks on this ruler. A Golomb ruler that has this nice property that each distance from 1 to the length of the ruler can be measured with it is called a perfect Golomb ruler. Unfortunately, there is a theorem that states that there are no perfect Golomb rulers with more than four marks. Must have been one of the lowest hanging fruits ever of mathematics.

Nonlinear twists of the imagination. Monday, January 13, 2014. Who cares if they listen? No, it wasn't Milton Babbitt who coined the title of that notorious essay, but it stuck. And, by the way, it was " Who cares if you. In a more dadaist spirit, there is this new release out now on bandcamp. Also titled Who cares if they listen. In these days there are enough reasons to care if they. Listen (yes they do, but not wittingly) and to worry about its consequences, as discussed in a previous post.

Nonlinear twists of the imagination. Monday, August 25, 2014. Q: Is this a concept album? A: Yes. Its subject matter is not only derived from those entertaining kooks who see shapeshifting reptilians on u-tube videos with their very own eyes, hence they must exist; there are also references to more serious topics such as the unhealthy state of affairs alluded to in this previous post.

Nonlinear twists of the imagination. Friday, November 1, 2013. The theoretical minimum of physics. What you need to know to start doing physics. By Susskind and Hrabovsky, 2013. This two hundred page book grew out of a series of lectures. A typical first semester physics text book may cover less theory than the theoretical minimum. Some quite easy and a few that take some time to solve. “You can be dumb as hell and still solve the problem”, as Susskind puts it in one of the lectures while...The theoretic...
