How to find some bombs, while still needing protection from others

28 Feb 2006 Elitzur-Vaidman bomb-testing problem:   This is a thought experiment in quantum mechanics, although its core has been realized in quantum experiments. The explanation given here is noteworthy, since it provides a glimpse into quantum logic and why no answer may sometimes mean that there is an answer, since the answer...

Double Slit Experiment revisited with video

26 Feb 2006 </embed> A really nice animation attempting to dissect  the century-old wonderings of whether subatomic particles are more like waves or more like..er..particles. Well, the question is just as amazing as watching you from the front and then from the back and then wondering how all of this could be you....

John Baez on our current standing in fundamental physics

26 Feb 2006 Fundamental Physics: Where We Stand Today: This is a fairly recent text from physicist John Baez. While it does carry a few equations (sounds like a bad thing, but heck, no!), it is a nice and concise summary on the state of affairs in our fundamental understanding of the reality...

Quantum computer solves problem, and it does run

23 Feb 2006 The title of this story is : “Quantum computer solves problem, without running” Quoting from physorg, one of the involved scientists said that “By placing our photon in a quantum superposition of running and not running the search algorithm, we obtained information about the answer even when the photon did...

A fine example of progress

23 Jan 2006 The C64 was the first computer I possessed. Now it can run without any troubles within a Java Applet container: Go here to check it out. It has a ton of games available, but I am missing some I played as well as the pure BASIC interface…:)
