Here he reviews and compares the quantum mechanical theories of consciousness by Henry Stapp, Evan Harris Walker, Roger Penrose and Sirag himself. All of these approaches are based on the principle enunciated in the 1930s by John von Neumann that consciousness is responsible for the collapse of the Schrödinger wave function. Each of them addresses [...]

Here he reviews highlights from the history of cosmology starting with Albert Einstein and Sir Arthur Eddington. He describes how Einstein modified some of his relativity equations in response to the astronomical observations of Edwin Hubble. He explains how Hubble’s work showed that the universe was much larger than our own Milky Way galaxy — [...]

Here he and Jeff reflect on their time together almost a half-century ago. Their memories include time exploring UFO phenomena, interacting with the famous Israeli psychic, Uri Geller, and living at the Institute for the Study of Consciousness in Berkeley, California. It was also a time of great ferment in the world of physics at [...]

Here he notes that modern interest in hyperspace began with the publication of the classic short novel, Flatland, by Edwin A. Abbott in 1884. Subsequently came the Kaluza-Klein theory that unified gravity with electromagnetism in 1921, requiring five spacial dimensions. Serious interest in hyperspace emerged in the 1970s with the development of string theory. Sirag [...]

Here he maintains that String Theory is important because it is the only physical theory to satisfactorily account for all four physical forces: electromagnetism, gravity, and the weak and strong nuclear forces. The theory possesses mathematical elegance and has also proven its value in making empirical predictions. He describes the different approaches used by mathematicians [...]

Here he points out that the original founders of quantum theory in physics generally believed that consciousness literally causes the collapse of the wave function. This is the standard, Copenhagen interpretation. He goes on to explore the Einstein Podolsky Rosen paradox, and Einstein’s objection to quantum theory, as well as Bell’s Theorem. Subsequent experiments by [...]
