Contemporary with the dinosaurs
2024-08-29 12:25 Plants has changed much since the time of the dinosaurs.  However, not so very much as many imagine.  Mosses, lycophytes and ferns existed long before the dinosaurs.
Real dinosaurs
2024-08-17 19:29 Some perceive dinosaurs as entertainment for children.  Dinosaurs are actually subject to scientific investigation.  As they are described today they make sense to me.  They make as much sense as platypuses, kangaroos and bats.
On the Permian-Triassic mass-extinction
2024-08-12 12:53 At the end of the Permian Pangaea was born.  Africa, Antarctica, Australia, South America and South Asia had long held together.  It is probably rather obvious how Africa and South America were stuck together.
Life before the dinosaurs
2024-08-07 16:56 Many imagine the early Earth as covered in molten rock.  Fact is the Earth’s crust solidified within a hundred million year after the birth of the Moon.  200 million years later the Earth was almost completely covered by seas.
The primeval myth
2024-06-13 13:53 I state points in prehistoric times for a good reason.  There is a myth of a vague “primeval time” when everything one knows about lived at the same time.  Then I mean different animals, larger than current ones and more or less strange.
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 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.
