The moving rocks, also known as sliding rocks or sailing stones, are a geological phenomenon found in Racetrack Playa, a seasonally dry lake (a playa) located in the Panamint Mountains in Death Valley NationalPark, California. The rocks move across the surface of the playa, leaving long tracks behind them Read more…
1900 – peak velocity =~ about 40mph ( crude representative WAG ) 1940 – we could go about 400 mph 1970 – 25000 mph Just eyeball estimating it appears that every 50 years we are 10X velocity capable. I assume this is due to a random process of technological invention in Read more…
When I was very young I was interested in the moon landing programs. I quickly homed in on the problem of propulsion in space. I also quickly became discouraged. I felt as though physics may never give us the present of the possibility of interstellar travel. This was the late Read more…

On my run today I noticed alot of yellow with black stripe caterpillars on the creosote bushes along the jeep trail at south mountain park. I found this photo on the web. It is a bit more green but is the caterpillar I saw. Common Caterpillars of SE Arizona ( Read more…

In a previous article entropy was defined as the expected number of bits in a binary number required to enumerate all the outcomes. This was expressed as follows: entropy= H(x)= In physics ( nature ) it is found that the probability distribution that represents a physical process is the Read more…
I am currently researching if D Wave has a public interface where one can submit jobs to one of their quantum computers. I have not found if they have yet but I have found one of the founders blog here: http://dwave.wordpress.com/ Seems to be throwing one machine open to the Read more…
Good presentation on adiabatic quantum computation. In information theory class I learned that by using the Laplacian form and maximizing entropy you can find the description of physical systems. The adiabatic minimization will work well in these scenario. Research Links Quantum Computation by Adiabatic Evolution An Analog Analogue of a Read more…
Very interesting and experimental approach to entanglement and Bells inequality.
