An object with a high albedo is shinier than an object with a low albedo. A white, completely reflecting object has an albedo of 1. Aldebaran is seen along the ecliptic.
One informal analysis suggests short first names are strongly correlated with higher salaries. They are bad in several ways, and modern glyphs are little better. For example, v and w, or m and n. People confuse them all the time, both in reading and in writing. Even though they share relatively few pixels, they are still identical under rotation, and we can see that.
We could confuse them if we were reading upside down, or at an angle, or just confuse them period.
OK, so we now have a set of unique and dissimilar glyphs that are unambiguous about their orientation. Well, we might want them to be easy to write as well as read.
How do we define easy to write? We could have a complicated physiological model about what strokes can easily follow what movements and so on, but we will cop out and say: Rather than unwritable pixels in a grid, our primitives will be little geometric primitives.
The fewer the primitives and the closer to integers or common fractions the positioning of said primitives, the simpler and the better. We throw all these rules in, add a random starting population or better yet a population modeled after the existing alphabet, and begin our genetic algorithm.
What 26 glyphs will we get? Dehaene describes some fascinating and convincing evidence for the first kind of innateness.
The relationship between the Catholic Church and science is a widely debated subject. Historically, the Catholic Church has often been a patron of sciences. It has been prolific in the foundation of schools, universities and hospitals, and many clergy have been active in the sciences. Historians of science such as Pierre Duhem credit medieval Catholic mathematicians and philosophers such as. Fideisms Judaism is the Semitic monotheistic fideist religion based on the Old Testament's ( BCE) rules for the worship of Yahweh by his chosen people, the children of Abraham's son Isaac (c BCE).. Zoroastrianism is the Persian monotheistic fideist religion founded by Zarathustra (cc BCE) and which teaches that good must be chosen over evil in order to achieve salvation. Website of Dr. Robert Lanza, M.D. From visionary physicist Scott Tyson’s new book “The Unobservable Universe” “I downloaded a digital copy of [biocentrism] in the privacy of my home, where no one could observe my buying or reading such a “New Agey” sort of cosmology book.
In one of the most interesting chapters, he argues that the shapes we use to make written letters mirror the shapes that primates use to recognize objects. After all, I could use any arbitrary squiggle to encode the sound at the start of Tree instead of a T.
But actually the shapes of written symbols are strikingly similar across many languages. It turns out that T shapes are important to monkeys, too.
When a monkey sees a T shape in the world, it is very likely to indicate the edge of an object - something the monkey can grab and maybe even eat.
A particular area of its brain pays special attention to those important shapes. Human brains use the same area to process letters. Dehaene makes a compelling case that these brain areas have been recycled We did not invent most of our letter shapes, he writes.
They lay dormant in our brains for millions of years, and were merely rediscovered when our species invented writing and the alphabet.
But who is to say that a butterfly could not dream of a man? You are not the butterfly to say so! Better to ask what manner of beast could dream of a man dreaming a butterfly, and a butterfly dreaming a man.
This is a reasonable objection.This is my last post for the Bad Astronomy Blog on Discover Magazine. As of today – Monday, November 12, – the blog has a new home at Slate magazine..
It has . As an amusing side note, in a science essay called "The Sight Of Home" Isaac Asimov once calculated how far an interstellar colony would have to be from Terra before Sol was too dim to be seen in the colony's night sky with the naked initiativeblog.com out that colonies further than 20 parsecs (65 light-years) cannot see Mankind's Homestar, because Sol's apparent magnitude is dimmer than 6.

There are those who in the realm of science fiction literature wonder if galactic empires are the new "Middle-Earth".But interstellar empires never seem to go out of style, and regardless of their practicality they remain a powerful meme.
The terrorist organization Aum Shinrikyo found inspiration in the galactic empire of Isaac Asimov's Foundation Trilogy.
