Energy is a central issue for the future, and we need a positive focus on where we can go. Accordingly, let us consider the Chinese pebble bed initiative: As a backgrounder, Wiki: The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor. It is a type of very-high-temperature reactor (VHTR), one of Read More…

At Phys.org: Scientists are unraveling the mystery of the arrow of time
Researchers: “Fundamentally, the arrow of time arises from the second law of thermodynamics: the principle that microscopic arrangements of physical systems tend to increase in randomness, moving from order to disorder.”
Apart from ID, nature cannot move towards more complex, functional systems.
At Quanta Magazine: A New Physics Theory of Life
Jeremy England: “You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said.
FOR REFERENCE: Globular Cluster M55 as illustrating apparent aging of our galaxy (& cosmos)
It seems helpful to illustrate cosmological scale apparent aging as stars depart main sequence: An idealised, Hertzsprung-Russell chart for Hydrogen-rich balls prone to become fusion furnaces is: Here is a comparative plot (for open clusters), constructing a “clock” by projected pattern as a cluster ages, in effect seeing what is left as a candle burns Read More…
Surprise, surprise, the aging process is irreversible
It’s nice to know that entropy is good for something.
Time’s arrow, the design inference on FSCO/I and the one root of a complex world-order (–> Being, logic & first principles, 25)
On August 7th, News started a discussion on time’s arrow (which ties to the second law of thermodynamics). I found an interesting comment by FF: FF, 4: >> It’s always frustrating to read articles on time’s arrow or time travel. In one camp, we have the Star Trek physics fanatics who believe in time travel Read More…
UD Guest Post: Dr Eugen S on the second law of thermodynamics (plus . . . ) vs. “evolution”
Our Physicist and Computer Scientist from Russia — and each element of that balance is very relevant — is back, with more. MOAR, in fact. This time, he tackles the “terror-fitted depths” of thermodynamics and biosemiotics. (NB: Those needing a backgrounder may find an old UD post here and a more recent one here, helpful.) Read More…
Would greater DNA harm enhance evolution or degradation?
Mutations are used to explain evolution but also cause cancer. Biologists have discovered conditions for multiple mutations. Can we therefore infer that evolution via mutations is more likely? or that enhanced mutations will cause faster species degradation and extinction? Biologists describe mechanism promoting multiple DNA mutations DNA mutations—long known to fuel cancer as well as Read More…
