The origin of human language
2024-09-29 15:54 Some imagine “cavemen” with a very limited language.  If they talk at all people imagine pidgin.  The present-day human species have never talked like that when people spoke their mother tongue.
The basics of geology
2024-06-23 17:03 Uniformitarianism is based on the idea of geology being explainable in terms of directly observable processes.  Certainly, processes can take place at different paces.  But this is still the same processes at different orders of magnitude.
Icehouse Earth and ice ages
2024-05-31 13:02 The climate during the last 550 million years is rather well-documented.  There have been several periods of tens of millions of years without any ice sheets.  The greenhouse effect was then considerably stronger than it is today.
Distances in space
2024-04-24 12:31 It can be hard to grasp exactly how empty space is.  The astronomer David Morrison once got the question:
The myth of the arbitrary movements of the heavenly bodies
2024-04-18 12:49 Many seem to lack basic knowledge on the movements of the heavenly bodies.  This applies to things like the following:
Radioactivity, fission and fusion
2024-04-12 12:52 Radioactivity is about certain elements – or variants of them – in course of time decaying.  Most such which has been found have never been observed to decay.  A smaller fraction has and then emit ionising radiation.
Absolute dating
2024-04-05 16:16 Oftentimes we can know how old something is.  Not just though written history as some have gotten stuck into.  It is entirely possible to find out the age of things with natural scientific methods too.
Orders of magnitude matters
2024-03-21 12:39 It is important to keep track of which order of magnitude something has.  Otherwise one’s concepts of nature risk becoming far too erroneous.  Which in turn creates needless fear.
The limits of oral tradition
2024-03-13 13:18 Among pseudohistorians there is an overconfidence in oral traditions.  Detailed knowledge of the past is believed to be passed on for millennia.  To me this appears preposterous.
The problems with UFO reports
2024-03-06 12:37 UFO was originally acronym for unidentified flying object.  Unfortunately, there are a lot believing everything which is unidentified have to be made by aliens.  The result is there now being “ufologists” defending this wrongful idea.
