I always wondered why a freeway with no accidents or other driver diversions such as a policeman pulling over a speeder can come to an almost complete halt. I think if have figured out this mystery. The following graph is velocity versus distance on a freeway. Here in Phoenix there Read more…

Genetic code is reused in exactly the same manner human programmers reuse code. Thus once some random string of genetic coding is found useful there is a process that preserves it from change. That change is called survival. If it is a random string with no purpose then it is Read more…
Louis DeBroglie does not get the credit he deserves for original thinking in quantum machanics – DeBroglie thesis paper – he won the Nobel Prize in 1929 for very good reasons which you will see if you read his thesis paper. I am looking for the single photon counter used Read more…
A reasonable strategy for learning QED would be to try to recreate Richard Feynman's path of discovery that lead him to his thesis paper. If you are an electrical or computer engineer you should probably set about the task of learning the subject for sooner or later quantum computing and Read more…
When memory elements become nonvolatile and can be configured as processing elements computing is going to start to use very different approaches. Behavoiral evolution approaches will become dominant. Professor Chua talks with a more mathematical presentation on the memristor.
Show that the curve: contains only one set of three distinct points, A, B, and C, which are vertices of an equilateral triangle, and find its area. The “curve” is actually reducible, because the left side factors as Moreover, the second factor is so it only vanishes at . Read more…
Do a long hand division of x greater than or equal to 1 does not result in convergence of this sum. However this algorithm can still be used to do some interesting things. Let us use a complex value of Each power of x yields a result one step around Read more…
The series: this converges for x < 1 : Both of these expressions are the Z transform of the exponential decay sequence. The first expression is easier to deal with because it is smaller and easier to work with. The following diagram uses a decay sequence with The filter Read more…
