# Comparative Mythology/Angelology

Welcome to the Angelology resource.
Angelology is the study of Angels it comes from Old English enġel, influenced in Middle English by Old French angele, both from Late Latin angelus, from Ancient Greek ἄγγελος (angelos), “‘messenger’”)
In this section I will try to present (remember) information concerning those Beings of Light known to us as Angels. You will find information that I have found and gathered together on various topics listed on the right and much more inside those pages. The portrayal of the synthesis for the sections: The Angelic Orders - The 7 Heavens, and The Archangels & Angels; was made by me using as much as possible the information in hand.
I came to believe that assisting others, brings joy to life, so I plan to share this information with everyone because... "freely you received... freely you shall give".
"We are, each of us angels with only one wing; and we can only fly by embracing one another".

# Comparative Axiology: Aesthetics & Ethics

Comparative Religion CORE 120
textbooks: Yoga Sutras Egyptian Book of The Dead Torah Dhammapada Plato's works any other philosophical/sacred text(s)
also examine: Earth's cultural/religious art

## Definition of Axiology

Axiology, i.e. aesthetics plus ethics, studies value: of beauty plus virtue, respectively. Aesthetics may be easier, but can show ethics' value: ethics are aesthetic. The 'great' religions (monotheisms and henotheisms) and even most pagan ones involve axiology.

## Introductory Philosophical (Platonic) Axiology

Read the following Platonic dialogues. The 1st ones listed are a good introduction; reasons to read the rest are given. It would be good to read some neo-Platonism afterwards.
Aesthetics: Symposium, beauty: Greater Hippias.
Ethics: Lysis; courage: Laches; moderation: Charmides; piety: Euthyphro; virtue: Republic (definition,) Symposium (benefits,) Meno (acquiring,) Gorgias (rhetorical,) Protagoras, Laws (society.)
Republic and Laws are long, but it is good to read them entirely; maybe just Republic's cardinal virtues section and as much of Laws as you want (at least skim through both.)

## Comparative Aesthetics

After familiarizing yourself with aesthetics, perhaps peruse Jungian psychology archetypes--or just compare some religious art.
Look at cultural and religious art: that of African, Australian, Amerindian, Middle Eastern, Semitic, Far Eastern cultures, Hellenismos, Slavianstvo, Celtic, Forn Siðr cultures and religions. A significant archetype in pagan religions is the world-tree, and in Hellenismos: Hermes' caduceus.
Look at religious art in the great religions: Sanatana/Hindu & Jain Dharma, Taoism (and Confucianism if applicable,) Mazdaism/Zoroastrianism, Amenism-Raism-Atenism, Judaism/Nazar(ean)s, Buddha Dharma, Nazar(ean)s/Christianity, Islam, Druze, Sikh Dharma, Bahai. Significant archetypes in Dharma are the Shaktis, and in Judaism are various Tree of Life ideas.
Recall your philosophical aesthetic knowledge; perhaps peruse Pythagorean and [neo-]Platonic mathematical images; postulate ethics' aesthetics; sum up your aesthetics ideas.

## Comparative Ethics

After familiarizing yourself with ethics, perhaps peruse (near) modern deist philosophy and compare it to ancient theism. Such as, read Egyptian Book of The Dead (Oaths/Commandments to/from Osiris,) Yoga Sutra (precepts,) Genesis (Edenic Laws, 10 Commandments,) Lao-tze's biography, Dhammapada (precepts.)
Compare the Eastern/Brahmic-Dharma precept ahimsa with Western/A-brah(a)mic Edenic Laws and Exodus & Deuteronomy (& Egyptian) harmlessness Commandments. Manichaenism, Sikhism, Bahai use those. Compare the Philosophy/Hellenismos Republic text sections on the guardians (philosopher-rulers of a Republic.) Many philosophers in those (and other) faiths consider ahimsa primary in ethics, which causes aesthetic life and society; consider it and sum up your ethics ideas.

## Comparative Axiology

Integrate aesthetics and ethics axiologically, and consider what episteme (knowledge, particularly scientific) this could lead to; prepare for epistemology.
# Comparative Mythology

Comparative mythology is the comparison of the myths of various cultures to identify common themes.

# Compact interval/Real function/Riemann integrable on partition/Fact

Let $I=[a,b]$ be a compact interval, and let
    $f\colon I\longrightarrow \mathbb {R}$
be a function. Then the following statements are equivalent.
* The function $f$ is Riemann-integrable.
* There exists a partition $a=a_{0}<a_{1}<\cdots <a_{n}=b$, such that the restrictions $f_{i}:=f|_{[a_{i-1},a_{i}]}$ are Riemann-integrable.
* For every partition $a=a_{0}<a_{1}<\cdots <a_{n}=b$, the restrictions $f_{i}:=f|_{[a_{i-1},a_{i}]}$ are Riemann-integrable.
In this situation, the equation
    $\int _{a}^{b}f(t)\,dt=\sum _{i=1}^{n}\int _{a_{i-1}}^{a_{i}}f_{i}(t)\,dt\,$
holds.
# Compact interval/Riemann integrable/Definite integral/Definition

Let $I=[a,b]$ denote a compact interval. For a Riemann-integrable function
    $f\colon I=[a,b]\longrightarrow \mathbb {R} ,t\longmapsto f(t),$
we call the upper integral of $f$ (which by definition coincides with the lower integral) the definite integral of $f$ over $I$. It is denoted by
    $\int _{a}^{b}f(t)\,dt{\text{ or by }}\int _{I}^f(t)\,dt.$

# Introduction

Source Filmmaker, abbreviated as SFM, is an animation program developed by Valve Studios. Released 2012, the program has helped thousands import their ideas into amazing recordings and videos.

## Quick History

Originally developed in tandem with the game Day of Defeat, an online multiplayer game, Source Filmmaker was built upon the Source Engine, an independent system program built from the ground up. In actuality, Source Filmmaker was developed internally by Valve for studio use. However, in 2012, Source Filmmaker was released to the public in an open beta. Since then, it has received multiple updates. Source Filmmaker has received numerous updates that included ported assets from various Valve titles, including Half-Life, Team Fortress 2, Day of Defeat, Left 4 Dead, and many more.

# Domain Name System

The Domain Name System is a hierarchical distributed database system that serves to translate string queries (such as http://www.wikipedia.org) into an IP address which a host may connect to. DNS is also utilised in email, where email address lookups are performed, and the relevant IP addresses returned.
To perform a lookup, a program known as a resolver is passed the string as a parameter. The resolver then sends a UDP packet to the local DNS server, which returns the IP address mapped to the string. Once the IP address is received, a TCP connection to the host may be established.

## Background

In the days of ARPANET, when the internet was in its infancy, a file known as hosts.txt contained a list of hosts and their corresponding IP addresses. Every night, all hosts connected to ARPANET would fetch an updated copy of this file from a central site. As the internet began to grow larger and larger, it became apparent that it was infeasible to continue with this approach.

## Top Level Domains

To begin a search for an IP address, we can choose to narrow our search down according to the type of website we are looking at. Common domain names include .com (commercial), .edu (educational) and .org (non-profit organisation). We can also seek a specific server by its country domain. For example, .co.uk belongs to the United Kingdom and .au belongs to Australia.

## Resource Records

These are the records that are handed back to the resolver based on the request it makes. The records are kept in ASCII text, and are presented with the following fields:

### Domain Name

    The domain to which the record applies. Multiple domains may exist, and they are all returned together to the resolver

### Time to Live

    A general indication of how long a record has before it can be considered out of date. Actual dates are not used here, rather, a value (678000 for example) is assigned to indicate how stable the record is. The lower the value, the more likely it would have changed recently.

### Type

    What kind of record we are looking at. More information will be provided below

### Value

| Type | Meaning | Value |
| A | IP address of host | 32 bit integer |
| MX | Mail Exchange | The domain that will accept mail |
| CNAME | Canonical Name | A fuller version of a domain name eg The CNAME of www.google.com is google.navigation.opendns.com |
