Plate tectonics and the origin of the continents
2024-06-28 12:53 Most know about continental drift.  What not as many know about, is the greater plate tectonics.  The Earth’s crust is divided in 8 – 10 pieces at least the size of continents.  (Two of the pieces are on the way to split in two each.)
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.
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.
What is radiation?
2024-04-10 12:06 A great deal seem to believe everything called “radiation” to be dangerous.  I think it is because the ionising was first payed attention to as such.  Which has then been overgeneralised to apply to all 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 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.
What is emergence?
2024-01-25 10:55 Emergence is when a phenomenon arises by itself.  This is about interactions between the different parts of the phenomenon and the surrounding environment.  As such there is no intention behind as some presupposes.
