After modifying the arduino program for measure radiation with cooking-hacks.com’s radiation board in a previous post, I realized that it wasn’t still perfect for background radiation measures: Background radiation measures are typically of very low values and given the stochastic nature of radiation (see graph on previous post), it takes some minutes to achieve a … Continue reading

# radiation detection with Arduino: cumulative counter

In a previous article, I used a radiation detection board adapted to the Raspberry Pi with an intercommunication board. But obviously the radiation detection board was primarily intended to use with Arduino. I used the code provided by the manufacturer, until I noticed that it wasn’t useful for real (amateur) radiation measurements: the radiation is … Continue reading

# radiation detection with Raspberry Pi

The Raspberry Pi is a nice piece of hardware. Moreover, it can be expanded with an “Arduino to Raspberry Pi connection bridge”, which allows it to interact with other boards made for Arduino. For example, sensor boards. In this case I’ve been playing with a sensor board for radiation detection. It is as cool as … Continue reading

# the problem of the 12 stones, revisited

There are 12 stones, 11 of equal weight, 1 of unequal weight (let’s say, lighter). By using a two-pan balance or a a pair of scales balance, can the lighter stone be found with just two measures? Well, the correct mathematical answer is no… The maximum number of stones amid of which the lighter ball … Continue reading

# opencl-toolbox 0.17 – installation steps on Matlab 2011a

How to install opencl-toolbox 0.17 (Jan 2011) for matlab: http://code.google.com/p/opencl-toolbox/ in Matlab 2011a under Windows 7 64 bits. The goal of opencl-toolbox is to provide an opensource toolkit that provides seamless integration of Matlab with OpenCL. MATLAB® is a high-level language and interactive environment for numerical computation, visualization, and programming. Open Computing Language (OpenCL) is … Continue reading

# The point of Maximum Attainable Complexity ת

What if scientific and technological progress couldn’t be sustained forever? What if advances have an upper limit? What if this limit could be measured… and predicted. I’ve tried to do so in this paper. I’m not sure if I’ve succeeded or not :) Decide it by yourself… read it: The point of maximum attainable complexity … Continue reading

# Do not disturb my circles: Noli turbare circulos meos

Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia. Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time. Unlike his inventions, the mathematical writings of Archimedes were little known in antiquity. The … Continue reading
