Quantum Measurement, Information, and Time (opens the original)
Read excerpt
This essay is an ambitious attempt to resolve a well-known physics paradox by introducing a concept that most physicists deny — that is, the existence of information in the abstract, independent of any physical medium like a computer chip or a brain. The paradox is called “the arrow of time”. The project of modern physics is to understand large-scale phenomena in terms of the interactions among sub-atomic particles. The paradox arises from the fact that in everyday life, time is a one-way street
The Paradoxical Politics of Climate (opens the original)
Read excerpt
When scientific controversies have major consequences for politics and profits, we’ve come to expect a thumb on the scale of scientific objectivity. The paradox in this case is that the thumb has switched sides. In 1965, Lyndon Johnson’s science panel was already warning of an effect on global climate from burning fossil fuels. At the time, the response was just what you might expect. The idea was suppressed, and never gained much traction. Privately, Exxon was studying the issue as a defensive
Pan-Psychicism? Are paranormal powers universal? (opens the original)
Read excerpt
In speaking of “perception”, I refer to direct knowledge of the environment, not mediated by any signals that present-day science knows how to measure. This is a radical hypothesis which has the advantage of being eminently testable. There is already evidence suggesting that plants and even microbes know what is around them without sense organs or nervous systems. I had heard about cases of “blindsight”. Children are reported to be able to read with their fingers. Blind cyclists who navigate tra
Does consciousness collapse the wave function? (opens the original)
Read excerpt
This is a big and important question that frames our understanding of QM. But beyond this there are implications for our view of physics and ontology = the nature of reality. An answer in the affirmative would imply that consciousness is a fundamental, irreducible element of reality. Consciousness does not depend on matter. It becomes natural to consider survival of individual awareness after death. The universal intuition that we have free will has a basis in our scientific paradigm. An answer
Exosomes, Hypothalamus, and the Body Clock (opens the original)
Read excerpt
Revolutionary technology has rejuvenated rats using exosomes from young pigs. The potential for translation to humans beckons us, but progress has been slow. The medical field, including aging medicine, is dominated by corporate science, and there is no clear path to controlling the intellectual property associated with exosomes. Nevertheless, there have been some interesting and promising developments in the last year. I believe that the body ages on a schedule. The schedule is governed by a bi
