Rader's NUMBERNUT.COM How to Read a Book 1. Open book. 2. 3. 4. Reading a book seems like a pretty straightforward task, doesn’t it? Why Do We Need Instructions on How to Read a Book? “Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.” In 1940, Mortimer Adler wrote the first edition of what is now considered a classic of education, How to Read a Book. He states that there are four types of reading: Elementary - This is just what it sounds like. This post will cover inspectional and analytical reading, and we’ll focus mostly on analytical. Analytical reading is where most readers fall short. How come people can’t read at a higher level? That’s our task today with this post. Inspectional Reading As mentioned above, there are certainly times when inspectional reading is appropriate. You can often get a pretty good feel for a book with inspectional reading by following the steps below. Read the title and look at the front and back covers of the book. Analytical Reading Why Read Analytically?
Wonders of Math - The Game of Life What is the Game of Life? by Paul Callahan Rules of the Game of Life Life is played on a grid of square cells--like a chess board but extending infinitely in every direction. A cell can be live or dead. A live cell is shown by putting a marker on its square. To apply one step of the rules, we count the number of live neighbors for each cell. A dead cell with exactly three live neighbors becomes a live cell (birth). Note: The number of live neighbors is always based on the cells before the rule was applied. In Life, as in nature, we observe many fascinating phenomena. The rules described above are all that's needed to discover anything there is to know about Life, and we'll see that this includes a great deal. Life Patterns A good way to get started in Life is to try out different patterns and see what happens. The R-pentomino is the first pattern Conway found that defied his attempts to simulate by hand. What Kinds of Objects Emerge in Life? Some other still lifes you will see are:
A Brief Guide to 3rd, 4th, and 5th Dimensional Time-Space Perception As a student of psychology in my youth, one of the things that fascinated me most was how in other “hard science” disciplines you could come up with incredibly freaky theories about shit like dark matter and quantum physics, then actually talk about them publicly without being laughed at. I suppose this is because of math, but if you break any of the aforementioned theories down too far, you’re basically dealing with the idea that humans can barely perceive the vast majority of what’s going on in the universe. Yet, say the same thing in regards to consciousness and it’s simply not tolerated. Goes against everything we believe in. What I find most hilarious about say, people getting super excited about things like string theory, is it doesn’t stand up to even the most basic of exploratory questioning. What about fucking insects? 3rd Dimensional Time-Space Perception In Gnostic terms, this would be referred to as the son (or daughter). 4th Dimensional Time-Space Perception

Study: People Far Away From You Not Actually Smaller PRINCETON, NJ—According to a groundbreaking new study published Thursday in The Journal Of Natural And Applied Sciences, people who are far away from you are actually not, as once thought, physically smaller than you. The five-year study, conducted by researchers at Princeton University, has shattered traditionally accepted theories that people standing some distance away from you are very small, and people close-by are very big. “The data was irrefutable in demonstrating that when someone standing directly in front of you begins walking away, their body does not, as previously assumed, gradually shrink before eventually disappearing entirely,” said Dr. David Pinard, lead author of the study. “Rather, our findings indicate that they maintain their original size regardless of how tiny they may appear.” This graphical representation explains the research team’s central hypothesis. “Indeed, people who are far away may, in actuality, be larger than you are,” Pinard added.
Puzzles and Tests (Archimedes Laboratory Project) New Year’s Resolution: Learn to Code A year ago I didn't know how to code. I had a journalism degree and had made some graphics, but I would have been hard-pressed to explain the difference between Ruby and JavaScript, and I was pretty happy when I got the YouTube video to embed correctly. I considered myself pretty technical but generally avoided the command line. When I did start learning, I was amazed by how much was out there: introductory videos, explanatory blog posts, tips and tricks and step-by-step guides. To get coding quickly, nothing beats having a project – and a deadline. As the year went on I came across a number of resources that were also very helpful in digging deeper: tutorial videos that finally cleared up some long-standing befuddlement, random snippets of code that made the damn thing work after three hours of head-banging, some really good explanations I wish I had read weeks earlier, etc. Ruby and Rails RailsCasts Screencasts for learning Rails.

Adopted Child Sick Of Gay Parents Forcing Him To Watch Them Have Sex LACONIA, NH—Saying that the experience has been highly detrimental to his development as a happy, healthy, and spiritually grounded member of society, local adopted child Nicholas Brown told reporters Thursday he has grown sick and tired of his homosexual parents always forcing him to watch while they have sex. Brown, a nine-year-old boy who ever since being taken in by same-sex partners Ethan and Thomas Brown has been repeatedly compelled to witness his adoptive parents have unrestrained sexual intercourse, claimed that these ongoing episodes have had an extremely deteriorative effect on his budding moral values. "Ever since I got here, it's the same routine every day: As soon as I get home from school, my dads lead me into their bedroom, lock the door, and make me watch them go at it for hours and hours," said Brown, emphasizing that this never-ending ritual has had a "toxic" effect on his impressionable young mind.
