“Chaos is merely order waiting to be deciphered”*…


Let us say we were interested in describing all phenomena in our universe. What type of mathematics would we need? How many axioms would be needed for mathematical structure to describe all the phenomena? Of course, it is hard to predict, but it is even harder not to speculate. One possible conclusion would be that if we look at the universe in totality and not bracket any subset of phenomena, the mathematics we would need would have no axioms at all. That is, the universe in totality is devoid of structure and needs no axioms to describe it. Total lawlessness! The mathematics are just plain sets without structure. This would finally eliminate all metaphysics when dealing with the laws of nature and mathematical structure. It is only the way we look at the universe that gives us the illusion of structure…

Science predicts only the predictable, ignoring most of our universe.  What if neither Platonism nor the multiverse are the accurate approaches to understanding the reality we inhabit?  “Chaos Makes the Multiverse Unnecessary.”

As we impose order, we might spare a thought for Philipp Frank; he died on this date in 1966. A physicist, mathematician, and philosopher of science, he was Einstein’s successor as professor of theoretical physics at the German University of Prague– a job he got on Einstein’s recommendation– until 1938, when he fled the rise of Nazism and relocated to Harvard.  Frank’s theoretical work covered variational calculus, Hamiltonian geometrical optics, Schrödinger wave mechanics, and relativity; his philosophical work strove to reconcile science and philosophy and “bring about the closest rapprochement between” them.

“Life could be horrible in the wrong trouser of time”*…


The challenge that the multiverse poses for the idea of an all-good, all-powerful God is often focused on fine-tuning. If there are infinite universes, then we don’t need a fine tuner to explain why the conditions of our universe are perfect for life, so the argument goes. But some kinds of multiverse pose a more direct threat. The many-worlds interpretation of quantum physicist Hugh Everett III and the modal realism of cosmologist Max Tegmark include worlds that no sane, good God would ever tolerate. The theories are very different, but each predicts the existence of worlds filled with horror and misery.

Of course, plenty of thoughtful people argue that the Earth alone contains too much pain and suffering to be the work of a good God. But many others have disagreed, finding fairly nuanced things to say about what might justify God’s creation of a world that includes a planet like ours. For example, there is no forgiveness, courage, or fortitude without at least the perception of wrongs, danger, and difficulty. The most impressive human moral achievements seem to require such obstacles.

Still, many horrifying things happen with nothing seemingly gained from them. And, Everett’s many-worlds and Tegmark’s modal realism both seem to imply that there are huge numbers of horrific universes inhabited solely by such unfortunates. Someone like myself, who remains attracted to the traditional picture of God as loving creator, is bound to find such consequences shocking…

How scientific cosmology puts a new twist on the problem of evil.  A theist wrestles with the implications of the “Many World” hypothesis: “Evil Triumphs in These Multiverses, and God Is Powerless.”

As we calculate our blessings, we might send carefully-addressed birthday greetings to Infante Henrique of Portugal, Duke of Viseu, better known as Prince Henry the Navigator; he was born on this date in 1394.  A central figure in 15th-century Portuguese politics and in the earliest days of the Portuguese Empire, Henry encouraged Portugal’s expeditions (and colonial conquests) in Africa– and thus is regarded as the main initiator (as a product both of Portugal’s expeditions and of those that they encouraged by example) of what became known as the Age of Discoveries.



“What’s a Multiverse?”*…


Last fall, a hand-picked group of the world’s top theoretical physicists received an invitation to a conference about the multiverse, a subject to which many of them had devoted the majority of their careers. Invitations like these were nothing unusual in their line of work. What was unusual was this conference was not being hosted by a university or research institute, but rather by a Scottish Duke.

And its organizer was not a physicist, but a landscape architect by the name of Charles Jencks.

The physicists were surprised to learn that Jencks had spent the past three years bringing their cosmological theories to life in the form of a massive land installation carved into the hills and pastures of the Nith Valley in southwest Scotland. It was titled “Crawick Multiverse” after the village where it was built, and its features, according to the brochure accompanying the invitation, included a Supercluster of Galaxies, twin Milky Way and Andromeda spiral mounds, the Sun Amphitheater (which seats 5,000), a Comet Walk, Black Holes (“in two different phases”), an Omphalos (a boulder-limned grotto symbolizing Earth’s “mythic navel” [pictured above]) and of course, the multiverse itself…

As we note, with Rebecca Solnit, that a path is simply a prior interpretation of the best way to traverse a landscape, we might send perpetual birthday greetings to Jean Bernard Léon Foucault; he was born on this date in 1819.  A physicist who made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope (although he did not invent it), Foucault is best remembered for the (eponymously-named) Foucault’s Pendulum– a long and heavy pendulum suspended from the roof of the Panthéon in Paris– demonstrating the effects of the Earth’s rotation.  In fact, essentially the same experimental approach had been used by Vincenzo Viviani as early as 1661; but it was Foucault’s work that caught the public imagination: within years of his 1851 experiment, the were “Foucault’s Pendulums” hanging– and attracting crowds–in major cities across Europe and America.
