## Virtuology

The main equation that Virtuology (VG) could be theorized is: VG: U D, which means: Virtuology: Upload Download. This equation, as I believe, is summarized the entire new science, i.e. Virtuology (VG). For example, it is used with MSCOW.7 It is implemented also in Large-scale Distributed Systems and Energy Efficiency. 8 Another study has M computers upload or download N contents. During the simulation process, each user selects a certain content to upload or download with a given probab...Looked up this term after coming across a reference to "virtuologist" in a Cyberpunk story.

## How a Nerd Walks Up the Stairs

Your steps should be in a cycle: short, long, long. Long in this case means a double step. Thus, you will cover five stairs in one short-long-long cycle. In addition, you should always start the first cycle on the same foot. Suppose you start on the left foot, then after two cycles you are back on the left foot, having covered ten stairs. While you are walking the stairs in this way, it is clear where you are in the cycle. By the end of the staircase, you will know the number of stairs modulo...29 SEP 2017 by ideonexus

## Roman Arithmetic

...basic Roman arithmetic is largely rather simple, even for those of us spoiled by Arabic notation. Addition is no sweat, because complex Roman numbers already use what math pros call additive notation, with numerals set beside one another to create a larger number. VI is just V plus I, after all. To add large numbers, simply pile all the letters together, arrange them in descending order, and there’s your sum. CLXVI plus CLXVI? CCLLXXVVII, or CCCXXXII. And one of the advantages of the Rom...24 DEC 2016 by ideonexus

## Number Scrabble: Numerical Tic-Tac-Toe

In psychological research on problem-solving, sometimes the game of Tic-Tac-Toe is employed, which, though very simple to learn and play, still offers sufficient problems to the investigator in that it is not at all clear what heuristics are used by the subjects, except avoiding the winning move of the opponent. The same is apparently true for the isomorphic game of Number Scrabble, which is based on the fact that there exists a 3 X 3 magic square, of which rows, columns, and main diagonals a... 4 |

## Alien Plot to Invade the Earth: First Undermine Faith in ...

“Given a time gap of forty thousand hours, the strategic value of any traditional tactics of war or terror is insignificant, and they can recover from them. To effectively contain a civilization’s development and disarm it across such a long span of time, there is only one way: kill its science.” The science consul said, “The plan focuses on emphasizing the negative environmental effects of scientific development and showing signs of supernatural power to the population of Earth. In ...16 FEB 2015 by ideonexus

## Religion and Racism

A meta-analytic review of past research evaluated the link between religiosity and racism in the United States since the Civil Rights Act. Religious racism partly reflects intergroup dynamics. That is, a strong religious in-group identity was associated with derogation of racial out-groups. Other races might be treated as out-groups because religion is practiced largely within race, because training in a religious in-group identity promotes general ethnocentrism, and because different others ...04 FEB 2015 by ideonexus

## Infinity Times Zero is Not Zero

The problem is that the laws of addition and multiplication you are using hold for natural numbers, but infinity is not a natural number, so these laws do not apply. If they did, you could use a similar argument that multiplying anything by infinity, no matter how small, gives infinity, thus ∞×0=∞. More sophisticated arguments can also be made, like ∞×0=limx→∞(x×1/x)=1. Clearly all these different values for ∞×0 mean that ∞ cannot be treated like other numbers. In order to ...**Folksonomies:**mathematics

## The Signaling Pathway

In a typical signaling pathway, proteins are continually being modified and demodified. Kinases and phosphatases work ceaselessly like ants in a nest, adding phosphate groups to proteins and removing them again. It seems a pointless exercise, especially when you consider that each cycle of addition and removal costs the cell one molecule of ATP—one unit of precious energy. Indeed, cyclic reactions of this kind were initially labeled “futile.” But the adjective is misleading. The additio...**Folksonomies:**neurology

## Simple Explanation of Big O Notation

The simplest definition I can give for Big-O notation is this: Big-O notation is a relative representation of the complexity of an algorithm. There are some important and deliberately chosen words in that sentence: relative: you can only compare apples to apples. You can't compare an algorithm to do arithmetic multiplication to an algorithm that sorts a list of integers. But two algorithms that do arithmetic operations (one multiplication, one addition) will tell you something meaningful; re...One of the best, down-to-Earth explanations of a concept that can get incredibly complex.
