A fourth law of thermodynamics as nature’s steepest entropy ascent?

Beretta;: every non-equilibrium state of a system or local subsystem for which entropy is well defined must be equipped with a metric in state space with respect to which the irreversible component of its time evolution is in the direction of steepest entropy ascent compatible with the conservation constraints.

What the universe looks like, via X-rays

A different view: This orbiting telescope was launched in July last year and despatched to an observing position some 1.5 million km from Earth. Once commissioned and declared fully operational in December, it was left to slowly rotate and scan the depths of space. eRosita’s first all-sky data-set, represented in the image at the top of this page, was completed only last week. It records over a million sources of X-rays. Jonathan Amos, “Breathtaking new map of the X-ray Universe” at BBC Still amazing.

Paul Nelson on methodological naturalism and scientists who don’t believe in it

Nelson: Now, you may think MN is unnecessary, or even unsound, for the practice of science. (Another time, I hope to discuss the surprising fact that many atheist scientists and philosophers disagree strongly with MN, when MN is proclaimed as an unconditional rule.) The National Academy, however, is not listening to you, nor are federal courts, Read More ›

Discussion of fine-tuning at Journal of Theoretical Biology

It would be nice to continue a civilized discussion of what fine-tuning means and implies in biology. Would incorporating an expectation of fine-tuning into biology hypotheses lead to quicker advances sooner? How will we test this—assuming that the village Darwin mob doesn’t storm the place, demanding that we shut down the discussion? Read More ›

Do universities still need intellectual freedom? Why?

At one time, a university education was a prized opportunity to be part of an intellectual elite. Academic freedom was a club rule because it served well in the days when Einstein and Bohr, to name just two, provided us with a much better understanding of physics by overturning all that we thought we knew in certain areas. But maybe things have changed. Read More ›

Michael Behe on how the new Lenski paper demonstrates a key problem with Darwinism

Behe: Let me emphasize: the only result from the decades-long, 50,000-plus generation E. coli evolution experiment that even seemed at first blush like it had a bit of potential to yield a novel pathway in the bacterium has resulted instead in spectacular devolution. Read More ›
