Living in a Quantum World: Scientific American

Quantum mechanics is not just about teeny particles. It applies to things of all sizes: birds, plants, maybe even people!

Imagining the Tenth Dimension: Infinite Division

How does the concept of infinite division relate to my approach to visualizing the dimensions? The answer is encoded into the logo I created for my project: at the core of this is the point we start with (the zero) and the point we end with (the ten), and those are connected. All of the other dimensions represent ways of dividing up the information that becomes reality, and so are shown in this graphic to be revolving around or “outside” the conceptual line which connects those starting and ending points. Those points, by virtue of being of indeterminate size, are really equivalent, but it’s helpful to think of the zero as representing the drive towards division down to the infinitesimally small, and the ten as representing the drive towards encompassing the infinitely large “point” of the Omniverse.

The Matrix as Metaphysics


The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me.

Metaphysical Idealism

First, let me dispel one of the greatest myths about idealism: Idealism does not deny the reality of the observable world.

No idealist (at least no sensible idealist) has believed that there is no observable world - that the world we see, hear, touch, smell and taste is not there at all.

Idealists typically believe in the existence of the observable world, just like everyone else. They do not regard the observable world as a figment of anyone’s imagination. What makes idealists different is their understanding of the nature of the observable world. Most people think of the observable world as something independent of minds - something that could continue to exist even if all minds were to disappear from the universe. Idealists go beyond this view; they think of the observable world as depending, in some way or other, on minds and the activities of minds. According to the idealist view of reality, if there had never been any minds of any sort in the universe, then there would not have been a universe at all. But the observable world is not merely something that people dream up. Some idealists (especially Berkeley, whom I discuss below) even have claimed that there is no matter - but by “matter” these idealists generally mean a non-mental, mind-independent substance. Claiming that the world is dependent on minds isn’t the same as claiming that the world isn’t really there!

Another common belief about idealism is that it is contrary to reason - or, as some people put it, “crazy.” This too is a myth that needs to be put to rest. Most idealistic thought, particularly in the West, is based on logical arguments of various sorts. In itself, idealism isn’t contrary to reason or logic. The worst that might be said is that it’s contrary to common sense. But this same charge can be leveled at many of our beliefs about the world - such as the true belief that the Sun is a star, which contradicts the common-sense observation that the Sun is just too big to be a star!

Still another myth about idealism is that idealism is contrary to science. Actually, the idealistic concept of the material world is logically compatible with the scientific view of matter. Idealism does not say that the natural world is unreal; it does not say that the laws of nature are mere inventions of the human mind; it does not say we can change the world magically by thinking differently. Nor does idealism place humanity at the center of the universe; it merely assigns conscious minds (of any kind, human or nonhuman) to a rather important role in the universe. Most of the best-known idealists of the western world have been either scientists or scientifically oriented philosophers. And as anyone knows who follows the popular scientific literature, some scientists start sounding like idealists when they discuss the picture of reality provided by quantum physics.

Also, idealism does not have any direct relation to the idea of “mind over matter.” Although idealism affirms that matter depends on mind, idealism does NOT require you to believe that your own mental processes (or even everyone’s mental processes together) can affect the actual course of material events. Some individuals who regard themselves as skeptics have associated idealism with belief in paranormal phenomena, and have tried to tar both beliefs with the same brush. Actually this is silly, since idealism neither supports nor contradicts belief in the paranormal.

Heresy in Science | hydrogen2oxygen

Vehemently suspect of heresy
Galileo was found “vehemently suspect of heresy“, namely of having held the opinions that the Sun lies motionless at the center of the universe, that the Earth is not at its center and moves, and that one may hold and defend an opinion as probable after it has been declared contrary to Holy Scripture. He was required to “abjure, curse and detest” those opinions.
He was sentenced to formal imprisonment at the pleasure of the Inquisition. On the following day this was commuted to house arrest, which he remained under for the rest of his life.
His offending Dialogue was banned; and in an action not announced at the trial, publication of any of his works was forbidden, including any he might write in the future.

Subversive Thinking: Atheism in the United States of America: Are the views on atheists hold by most Americans ONLY the product of prejudice or bigotry?

Scientific evidence suggests that, in United States, atheists are considered the most distrusted minority.

Many of the study’s respondents associated atheism with an array of moral indiscretions ranging from criminal behavior to rampant materialism and cultural elitism.

Edgell believes a fear of moral decline and resulting social disorder is behind the findings. “Americans believe they share more than rules and procedures with their fellow citizens—they share an understanding of right and wrong,” she said. “Our findings seem to rest on a view of atheists as self-interested individuals who are not concerned with the common good.”
