In honor of National Robotics Week 2013 (April 6-14) I am adding this article that I originally posted on my Society of Robots blog page. In this article you will learn how to build a…

The solution to the Jailer’s Revenge question is fairly lengthy, so I think it warrants a separate blog entry. Please refer to the original question as it too is fairly long. Let’s firstly simplify…

In my previous blog post, Build a Simple Tone Generator with the 555 Timer IC, I successfully demonstrated how to build a simple tone generator, but when I tried to demonstrate how to build a…

If there is a contentious and politicized branch of science today it is climate science. Either it's global warming, or global cooling, but we have settled on climate change, just in case it goes in…

The Alpha Magnetic Spectrometer has found is that there are interesting features in the cosmic ray background which could indicate dark matter particle anti particle annihilations.  That is…

To those who follow my twitter account: my account was hacked over a week ago, and only today could I get it back to work (the twitter support team is not -hehm- a prize-winning one). So while I am…

A ground breaking paper has been published in the journal of comparative irrelevance which shows the Lambda CDM model is wrong.  It's all in the numbers..This theory explains everything better…

I have decided to rescind this proposal.  Stars in a galaxy travel at one velocity, light at the speed c.  There is only one velocity involved in applying the product rule to the definition…

OK, here's the premise.  The Audubon Nature Institute has something they call a "frozen zoo" (1) which contains genetic material from endangered species.  In this way recently extinct…

The velocity profile of thin disk galaxies is a riddle worth pondering. Studies have shown that the velocity of stars in a galaxy rise to a peak as one leaves the center, and then stays flat as one…

Maintaining a Curriculum Vitae (CV) regularly is an important activity for researchers mainly driven by the need to show the impact of his/her research during hiring, promotion, grant…

fMRI has always been a little misused, to people who know what they are talking about. 20 years after it was first done, the promise seems to have been overrun by agenda-based cultural mapping.…

Sometimes there is a story with no winner and a bunch of losers.  In this case, first among the losers are wind energy subsidies squandered on companies that aren't doing much good at all to…

Most people drink alcoholic beverages without actually knowing what happens to it as it enters into their body. "A hangover" is a common thing alcohol drinkers know, or maybe they have heard that…

And so here it is, the first public Landsat 8 image. The geographical honours goes to Wyoming and Colorado and the area where the Great Plains meets the Rocky Mountains in USA. I wrote about the…

From the perspective of one theoretical particle physicist Planck found far from "nothing". The ESA's Planck probe largely corroborates the findings of NASA's WMAP probe, but it leaves theoretical…

"...spend one year one mile underground to stare at a bucket of xenon ... only to come out for your zen moment and profoundly declare "nothing happened" ... and then you spend twice as long…

Before discussing the recent Planck results and my opinion on the present situation, let me present here an extract of my ICFP 2012 paper Pre-Big Bang, fundamental Physics and noncyclic cosmologies,…

Sorry, I again spent a long time without writing anything here... I hope you are having a happy 2013 in spite of all kinds of "sequestrations" on both sides of the Atlantic. Here are my two last…

It is time that we in the US stop outsourcing research. By this, I refer to the overwhelming dependence we have on research talent brought here from overseas. This is true in the universities in all…
