Dangers of radiation in the home
2008-04-06 07:08:08
The best Swedish site for news on technology, in my opinion, is www.idg.se. Today they have an article on radiation in the home. The article is based on an interview with Maria Feychting professor in epidemiology at Karolinska Institutet. The article discusses the danger of the radiation associated with products that are becomming increasingly common in ordinary homes. I am speaking of mobile phones, routers, wireless keyboards and mice, bluetooth headsets and dect phones.The conclusion of the article, briefly put, is that there are no scientific evidence that this radiation causes any harm. It is a fact that studies showing potential dangers of radiation get much more attention than studies which show zero effects, even though the latter type are much more common. Furthermore, most of th


MIT open courses

Nobody could have missed that I love to listen to audio and video lectures on my spare time. In particular when I am doing something where I do not have to concentrate (such as doing dishes or walking the dog). I recently wrote about The Teaching Company which is probably my favorite company in the world. I have also mentioned Berkeley webcast and in particular the lecture series called physics for future presidents taught by professor Richard A Muller.When reading Lunkens blog I saw some really good news. MIT, one of the most prominent Universities in the world (particularly in physics, technology, and computer science), have been inspired by Berkeley and have now made a good deal of their courses available online for free, hurray for that! For example, here is a lecture series on introdu


Debunking christianity

In this post I would like to promote another blog which I have just been reading. It is called Debunking Christianity () and it seems to be high quality posts. Here is the authors (there are several different contributors) own description of their blog:"This Blog has been created for the purpose of debunking Evangelical Christianity. We are ex-Christians, ex-ministers, and even ex-apologists for t


Magical mathematical tricks
2008-06-08 04:23:26
Parallell to working on forthcoming articles I have been listening to the Teaching Company series called "The joy of mathematics", taught by professor Arthur T. Benjamin (see picture).It is a truly great series of lectures which has allowed me to fresh up my math as well as to learn som impressive new skills. For example I can now square any number between 1-100 very fast (perhaps I will reveal th

How to square any number between 1 and 100
2008-06-12 02:37:33
In my post on magic mathematical tricks I claimed to be able to easily square any number between 1-100. Later I got a comment enquiring about this claim, according to my reader there is only a calculation "fast track" for numbers ending with 5, i.e. 5, 15, 25, 35, 45, 55 etc, and not for all the other numbers between 1-100.The fact of the matter is that numbers ending with 5 are particularly easy


Plato and totalitarianism
2008-07-13 10:40:13
Plato (see picture) was a philosopher born at the beginning of the Peloponnesian war which raged from about 430BC to 400BC. Plato is correctly given a lot of credit for being a very influential philosopher, indeed he thought and wrote about most areas of philosophy during his lifetime. For this he is very much admired, so much in fact that critical voices tend to drown in this ocean of admiration.

Religion as refuge
2008-07-31 03:46:34
Christianity as well as most other religions are, I believe, false in the sense that their view of the world do not agree with the world as we perceive it. However, one might ask why false theories flourish so much. Would so many people believe in something which is false? My answer to this is obviously, yes they would! Here I want to propose one explanation of why there is religion. Last tim

Popular fallacies of alternative and complementary medicine
2008-09-07 09:25:28
In the most recent issue of the magazine "Skeptic", Harriet Hall, also known as "SkepDoc" writes about three fallacies that you will encounter very frequently if you engage in discussion about alternative or complementary medicine. I will of course not plagiarize Hall's article, but what I am writing here is her article, filtered through my brain (I have written about related matters here and here


Apollonius of Tyana

About 2000 years ago a pregnant woman got a visit from a heavenly agent who told the mother-to-be that her son would be the son of God. His birth which was associated with some supernatural signs and as a boy he made himself a name among the religious leader. When he got older he left his home to walk around from town to town and convinced people to give up on their material belongings and instead


The New Testament and “Russian scandal”
2008-09-29 08:02:25
There are many ways in which The New Testament is a great book. It has been read by many people (to say the least), it gives many people guidance in their lives and has done so for many years, and it also serves as historical evidence for the character named Jesus.It is on this last point that I want to expand here. Having recently listened to two different courses from the always fabulous "Teachi

Positive psychology and the hedonic treadmill
2008-10-16 07:13:12
How happy are you on a scale from 1-10, with 5 being the average individual? If you are like most people you think that you are happier than most people (7-8 is the average answer you get). But what factors affect your life satisfaction?This post has been inspired by yet another fantastic professor that everyone with an internet connection can (and should), listen to. His name is Paul Bloom and hi
