Perhaps there are many "nows" of varying duration, depending on just what it is we are doing. We must face up to the fact that, at least in the case of humans, the subject experiencing subjective time is not a perfect, structureless observer, but a complex, multilayered, multifaceted psyche. Different levels of our consciousness may experience time in quite different ways. This is evidently the case in terms of response time. You have probably had the slightly unnerving experience of jumping at the sound of a telephone a moment or two before you actually hear it ring. The shrill noise induces a reflex response through the nervous system much faster than the time it takes to create the conscious experience of the sound. It is fashionable to attribute certain qualities, such as speech ability, to the left side of he brain, whereas others, such as musical appreciation, belong to processes occurring on the right side. But why should both hemispheres experience a common time? And why should the subconscious use the same mental clock as the conscious? ↗

I spent eighteen months as a graduate student in physics at Columbia University, waiting unhappily for an opportunity to work in a laboratory and wondering if I should continue in physics. ↗

In 2002, having spent more than three years in one residence for the first time in my life, I got called for jury duty. I show up on time, ready to serve. When we get to the voir dire, the lawyer says to me, “I see you’re an astrophysicist. What’s that?” I answer, “Astrophysics is the laws of physics, applied to the universe—the Big Bang, black holes, that sort of thing.” Then he asks, “What do you teach at Princeton?” and I say, “I teach a class on the evaluation of evidence and the relative unreliability of eyewitness testimony.” Five minutes later, I’m on the street. A few years later, jury duty again. The judge states that the defendant is charged with possession of 1,700 milligrams of cocaine. It was found on his body, he was arrested, and he is now on trial. This time, after the Q&A is over, the judge asks us whether there are any questions we’d like to ask the court, and I say, “Yes, Your Honor. Why did you say he was in possession of 1,700 milligrams of cocaine? That equals 1.7 grams. The ‘thousand’ cancels with the ‘milli-’ and you get 1.7 grams, which is less than the weight of a dime.” Again I’m out on the street. ↗
David Park is a physicist and philosopher at Williams College in Massachusetts with a lifelong interest in a time which he too thinks doesn't pass. For Park, the passage of time is not so much an illusion as a myth, "because it involves no deception of the senses.... One cannot perform any experiment to tell unambiguously whether time passes or not." This is certainly a telling argument. After all, what reality can be attached to a phenomenon that can never be demonstrated experimentally? In fact, it is not even clear how to think about demonstrating the flow of time experimentally. As the apparatus, laboratory, experimenter, technicians, humanity generally and the universe as a whole are apparently caught up in the same inescapable flow, how can any bit of the universe be "stopped in time" in order to register the flow going on in the rest of it? It is analogous to claiming that the whole universe is moving through space at the same speed—or, to make the analogy closer, that space is moving through space. How can such a claim ever be tested? ↗
Originally I had planned to revert to nuclear physics there, in particular the structure of the deuteron. ↗
That afternoon She listened to the grievances of the dead from two warring nations. Both sides had suffered, both sides had legitimate grievances, both pled their cases earnestly. She covered Her ears and moaned in misery. She knew Her humans were multidimensional and She could no longer live under the rigid architecture of Her youthful choices. ↗
We have learnt that the exploration of the external world by the methods of physical science leads not to a concrete reality but to a shadow world of symbols, beneath which those methods are unadapted for penetrating. Feeling that there must be more behind, we return to our starting point in human consciousness - the one centre where more might become known. There we find other stirrings, other revelations than those conditioned by the world of symbols... Physics most strongly insists that its methods do not penetrate behind the symbolism. Surely then that mental and spiritual nature of ourselves, known in our minds by an intimate contact transcending the methods of physics, supplies just that... which science is admittedly unable to give. ↗
We look for the Secret - the Philosopher's Stone, the Elixir of the Wise, Supreme Enlightenment, 'God' or whatever...and all the time it is carrying us about...It is the human nervous system itself. ↗
