The Biocentric Universe: Animal Wonders and Stargazing Scarabs
“Light is Life” – H. P. Blavatsky
OCCULTISM connotes by the word God, “the symbolic conception of the Life and Motion of the Universe.”
This is in stark contrast to the crude anthropomorphism, which is still the backbone of our current theology.
“The One Life is deity itself, immutable, omnipresent, eternal,” says the teaching of Theosophy.
And the distinction “between organic and inorganic…

Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists
YAY! Score another for the “quantum weirdness”! I’m honestly glad that it still remains a mystery and that the macro and micro worlds aren’t behaving the same.
The Experiment
“It’s happening, but I don’t believe it!” Katherine exclaimed as her eyes filled with astonishment at what she was witnessing. “It’s completely inexplicable….” The awe in her voice was enough to lift George from his seat, the origami he had been folding collapsing onto the lab’s pristine countertops.
“Are you serious?” He asked, not quite willing to believe that their efforts could have really brought about the results they had so desperately wanted to confirm. “You’re telling me that these findings were real? I’m going to look on that screen and see two straight, vertical lines?”
“See for yourself,” She turned the computer monitor towards him and heard his gasp. There on the monitor were two straight, vertical lines, marking the spots where every single electron had landed. “No interference pattern! They went straight through, and the only difference is that we were watching those little devils.”
“There’s no way,” his eyes were bulging, his mouth agape, “How can it be possible that by the mere act of observation we have changed the behavior of these particles, and not just any particles mind you, but some of the most fundamental particles in the universe?” The double-slit experiment they had performed had shown that, by simple observation, the motion of electrons being blasted through the two slits changed from that of a wave to that of individual particles. It was as though the physical properties of the universe had been affected by the device used to measure the location of each electron.
“Do you think it’s true, then?” Katherine inquired of George.
“Do I think what is true?”
“A watched pot never boils. A watched clock never ticks. What if the way we see things isn’t just in our heads. What if by looking at something we are actually altering its behavior?
“But how could that be?” George began to retort.
“How could this be? What is causing this? Should it be any more possible that we can change the very nature of an electron with our gaze than it is that we might slow down time, or stop the transfer of energy from one body to another?”
George had to think about this. These thoughts clouded his mind and he could feel the weight of a thousand questions begin to bury him. His brain was becoming a tumultuous landscape of new ideas and possibilities. All that he had once thought was certain now became an endless sea of unknowing. “So what does this teach us about the world we live in?” He wondered aloud.
“It teaches us nothing. All we now know is that there is so much more to learn than we ever thought before. The world, as we had previously seen it, is not the world we live in. The mysteries are now more bountiful than ever!”
“Well that was a waste of time.” George propped up his origami paper and continued to fold.
The Schrödinger (yes, the same Schrödinger) equation, or wavefunction– which describes how the quantum state of a physical system changes with time – when both slits are open differs slightly from the sum of the wavefunctions with the two slits alternately open. The problem is that the three alternatives (slits A and B, slit A, slit B) correspond to separate boundary conditions – equations that specify the behavior of the solution to a system of differential equations at the boundary of that system's domain – meaning that superposition does not apply. Recently, however, scientists at the Raman Research Institute and the Indian Institute of Science, both in Bangalore, India, theoretically resolved this paradox by quantifying nonclassical path contributions in quantum interference experiments using the Feynman path integral formalism, which involves an integration over all possible paths that can be taken by the particle through the two slits, thereby calculating a quantum amplitude by replacing the classical notion of a single, unique trajectory for a system with a sum, or functional integral, over an infinite number of possible trajectories. This allows them to replace the approximate wavefunction with both slits open (ψAB = ψA + ψB) with an integral that includes both the classical paths – the nearly straight paths from the source to the detector through either slit – and the nonclassical, or looped, paths that make a small but finite contribution to the total intensity at the detector screen (ψAB = ψA + ψB + ψL). In so doing, they successfully quantified the effect of such nonclassical paths in interference experiments, which in turn quantifies the deviation from the common but incorrect application of the superposition principle in different possible experimental conditions. Although the researchers acknowledge that it would be difficult to create a direct experimental demonstration of the existence of these nonclassical paths, they conclude that since contributions from such paths can be significant. They therefore propose simple three-slit interference experiments to directly confirm their existence.
