A controversial study with the homeopathic remedy Rhus tox got retracted. But what is the remedy actually made from according to the authors?
My attention was drawn to a study via Twitter by a guy named Sam Little who is involved in some dubious test with the well known and dangerous quack product MMS [23/5/2019 see update below]. He recently performed a test in Uganda which is very similar to the test that was performed in Uganda several […]
On 12 June 2018, I published a book review of Patronen van Bedrog, a book written by Willem Middelkoop and Tim Dollee. The title translates into Patterns of Deception. In this review (published on Kloptdatwel.nl) I argue that this is not a very good book, to say the least. It repeats conspiracy theories thrown up […]
According to truthers NIST had to admit reluctantly that WTC7 came down at free fall. My analysis shows that the calculation of NIST is questionable and that an argument can be made that the acceleration was a bit lower than the free fall acceleration.
It is possible to approximate pi with throwing needles on a grid, but the result Italian mathematician Mario Lazzarini published in 1901 seems too good to be true. But was it fraud? A close look into his original paper sheds some new light on this issue.
Two years ago Ruggero Santilli sued me for defamation. He was not pleased by some sentences in a post I wrote about one of his inventions, the Santilli Telescope. This telescope with concave lenses can detect ‘anti-matter light’, which is something completely different from ordinary light according to the genius from Florida. He also sued professor Frank Israel, chairman of the board of Stichting Skepsis, and my web host, Hosting2Go. The lawsuit has now been settled. I’ll give you an update on what happened in those two years.
Organic farming has quite some influences from pseudoscientific ideas as can be seen in the preference for alternative medicine in treating livestock. Surprisingly, EU regulations for the organic food label are slightly different and worse than those from the FAO, looked upon from the perspective of animal well-being.
On places where you can cross the equator, you can find people demonstrating the Coriolis effect for tourists. These performances are actually tricked as the effect is too small to be observed in this way. One guy in Uganda tricks the tourists in another way, but it is unclear whether he realises this himself.
The test for allergies and food intolerance used by Test Your Intolerance are based on bioresonance, which is useless quackery. The company admits there is no scientific evidence for their tests.
Eltjo Haselhoff proposed a physical hypothesis for the apparent anomalies in the flattened crops in crop circles. His theory was contested by Italian skeptics. Both the Italians and Haselhoff missed a pretty obvious reason to dismiss the BOL theory straight away.
