The End Of A Physics Worldview: Heraclitus And The Watershed Of Life

At the dawn of Western philosophy and science, some 2,700 years ago, Heraclitus, declared that, "the world bubbles forth." There is, in this fragment of thought, a natural magic, a creativity beyond the entailing laws of modern physics. I believe Heraclitus was right about the evolution of the biosphere and human life. We live beyond entailing law in a natural magic we co-create.

Early sociologist Max Weber said that with Isaac Newton, we became disenchanted and entered modernity. He was right. Before Newton, our tradition from Genesis saw a creator God whose divine agency, rather like the natural magic of Heraclitus, created the world also beyond entailing law.

With Newton's three laws of motion, universal gravitation and the differential and integral calculus, our world transformed profoundly. Given the initial and boundary conditions of billiard balls on the table, and the shape of the table, and their motions given in differential equation form using the laws of motion, integration, a form of deduction, yielded the entire future and past trajectories of the balls. With Pierre-Simon Laplace, this became the bedrock of reductionism: Given the positions and momenta of all the particles in the universe, a vast intelligence could, using Newton's laws, deduce the entire future and past of the universe.

The framework of entailing laws remains in the twin pillars of 20th-century physics, general relativity and quantum mechanics, with differential equations and their entailed integration.

I believe we reach a terminus of this physics worldview at the watershed of life. Heraclitus was right: Life bubbles forth in a natural magic. We stand to be re-enchanted and may find our way beyond modernity to something very new.

This post summarizes points from previous posts, but goes beyond them in several important ways to make the strongest case possible for our living with "natural magic."

First, evolution itself defies both the completeness of quantum mechanics and the completeness of classical mechanics and unites them both. Mutations are often quantum random and indeterminate events, yielding Darwin's heritable variation. Yet evolution itself is not random, seen in convergent evolution. For example, the stunning near identity of the octopus and vertebrate camera eye evolved independently. More examples are found in convergent evolution of marsupials and mammals.

NASA launches mission to Jupiter - physicsworld.com

NASA has launched a mission to Jupiter that will shed light on the origin and inner structure of the largest planet in our solar system. The $1.1bn Juno probe was launched today from Cape Canaveral, Florida, at 12.25 p.m. local time and will now begin a five-year journey to the planet.

Juno, named after the wife of the Roman god Jupiter, is the second probe to orbit Jupiter. The first was NASA's Galileo satellite, which launched in 1989 to the planet and its moons. Other craft have also since travelled near Jupiter on their way to other planets such as the Saturn-bound Cassini-Huygens mission, which was launched in 1997 by NASA and the European Space Agency.

While these missions did not deviate far from the equator of Jupiter, Juno will enter a highly elliptical orbit around the poles of the planet. "This will allow us to gain access to the entire volume of space around Jupiter for the first time," says Jack Connerney, from NASA's Space Goddard Flight Center, who is lead instrument scientist of the mission.

While in orbit, Juno will study the planet's atmosphere, gravity and magnetic fields as well as attempt to answer how the planet formed and whether it has a rocky core. It will do this via nine onboard instruments, which include a camera, magnetometer, microwave radiometer and spectrometer.

Jupiter's magnetic field is around 20,000 times greater than that on Earth, producing the largest magnetosphere of any planet in the solar system. It will be mapped in unprecedented detail by Juno, possibly revealing details about its origin. "We are sending to Jupiter the most capable and accurate magnetic observatory to ever venture into deep space," adds Connerney.

Juno will use three solar arrays for propulsion, making it the furthest distance a solar-powered probe has travelled in the solar system. Previous missions such as Cassini-Huygens or the Pioneer craft generated power via the heat released from the decay of radioactive particles.

Juno will operate for a year, completing 32 orbits around Jupiter, which each take around 11 days. The probe will then be made to crash into the planet. In addition to the nine instruments, Juno is also carrying a plaque, provided by the Italian Space Agency, dedicated to the famous astronomer Galileo Galilei, as well as three 3.8 cm-tall LEGO figurines of Galileo, the Roman god Jupiter and his wife Juno.

The mission is the second spacecraft of NASA's New Frontiers programme. The first was the Pluto New Horizons mission, which launched in January 2006 and is scheduled to reach Pluto's moon Charon in 2015.
