Dementia

Dementia, also known as senility, is a broad category of brain diseases that cause a long term and often gradual decrease in the ability to think and remember that is great enough to affect a person's daily functioning. Other common symptoms include emotional problems, problems with language, and a decrease in motivation. A person's consciousness is usually not affected. A dementia diagnosis requires a change from a person's usual mental functioning and a greater decline than one would expect due to aging. These diseases also have a significant effect on a person's caregivers.

binary numbers and letter meaning

Cross-like marks and graphemes[edit]

Further information: X mark

The cross mark is used to mark a position, or as a check mark, but also to mark deletion. Derived from Greek Chi are the Latin letter X, Cyrillic Kha and possibly runic Gyfu.
Egyptian hieroglyphs involving cross shapes include ankh "life", ndj "protect" and nfr "good; pleasant, beautiful".
Sumerian cuneiform had a simple cross-shaped character, consisting of a horizontal and a vertical wedge (𒈦), read as maš "tax, yield, interest"; the superposition of two diagonal wedges results in a decussate cross (𒉽), read as pap "first, pre-eminent" (the superposition of these two types of crosses results in the eight-pointed star used as the sign for "sky" or "deity" (𒀭), DINGIR). The cuneiform script has other, more complex, cruciform characters, consisting of an arrangement of boxes or the fourfold arrangement of other characters, including the archaic cuneiform characters LAK-210, LAK-276, LAK-278, LAK-617 and the classical sign EZEN (𒂡).^[15]
Phoenician tāw is still cross-shaped in Paleo-Hebrew alphabet and in some Old Italic scripts (Raetic and Lepontic), and its descendant T becomes again cross-shaped in the Latin minuscule t. The plus sign (+) is derived from Latin t via a simplification of a ligature for et "and" (introduced by Johannes Widmann in the late 15th century).
The letter Aleph is cross-shaped in Aramaic and paleo-Hebrew.
Egyptian hieroglyphs with cross-shapes include Gardiner Z9 – Z11 ("crossed sticks", "crossed planks").
Other, unrelated cross-shaped letters include Brahmi ka (predecessor of the Devanagari letter क) and Old Turkic (Orkhon) d² and Old Hungarian b, and Katakana ナ na and メme.
The multiplication sign (×), often attributed to William Oughtred (who first used it in an appendix to the 1618 edition of John Napier's Descriptio) apparently had been in occasional use since the mid 16th century.^[16]
Other typographical symbols resembling crosses include the dagger or obelus (†), the Chinese (十, Kangxi radical 24) and Roman (X) ten.
Unicode has a variety of cross symbols in the "Dingbat" block (U+2700–U+27BF) :

✕ ✖ ✗ ✘ ✙ ✚ ✛ ✜ ✝ ✞ ✟ ✠ ✢ ✣ ✤ ✥

The Miscellaneous Symbols block (U+2626 to U+262F) adds three specific Christian cross variants, viz. the Patriarchal cross (☦), Cross of Lorraine (☨) and "Cross of Jerusalem" (implemented as Cross potent, ☩).

The Bible teaches that God created human beings in His image. This means that He enables us to have some understanding of Him and of His vast and complex design.

                                                                                    

evangelii gaudium

Star of the new Evangelization
287. We ask the Mother of the living Gospel to intercede that this invitation to a new phase of evangelization will be accepted by the entire ecclesial community. Mary is the woman of faith, who lives and advances in faith,[214] and “her exceptional pilgrimage of faith represents a constant point of reference for the Church”.[215] Mary let herself be guided by the Holy Spirit on a journey of faith towards a destiny of service and fruitfulness. Today we look to her and ask her to help us proclaim the message of salvation to all and to enable new disciples to become evangelizers in turn.[216] Along this journey of evangelization we will have our moments of aridity, darkness and even fatigue. Mary herself experienced these things during the years of Jesus’ childhood in Nazareth: “This is the beginning of the Gospel, the joyful good news. However, it is not difficult to see in that beginning a particular heaviness of heart, linked with a sort of night of faith – to use the words of Saint John of the Cross – a kind of ‘veil’ through which one has to draw near to the Invisible One and to live in intimacy with the mystery. And this is the way that Mary, for many years, lived in intimacy with the mystery of her Son, and went forward in her pilgrimage of faith”.[217]
288. There is a Marian “style” to the Church’s work of evangelization. Whenever we look to Mary, we come to believe once again in the revolutionary nature of love and tenderness. In her we see that humility and tenderness are not virtues of the weak but of the strong who need not treat others poorly in order to feel important themselves. Contemplating Mary, we realize that she who praised God for “bringing down the mighty from their thrones” and “sending the rich away empty” (Lk 1:52-53) is also the one who brings a homely warmth to our pursuit of justice. She is also the one who carefully keeps “all these things, pondering them in her heart” (Lk 2:19). Mary is able to recognize the traces of God’s Spirit in events great and small. She constantly contemplates the mystery of God in our world, in human history and in our daily lives. She is the woman of prayer and work in Nazareth, and she is also Our Lady of Help, who sets out from her town “with haste” (Lk 1:39) to be of service to others. This interplay of justice and tenderness, of contemplation and concern for others, is what makes the ecclesial community look to Mary as a model of evangelization. We implore her maternal intercession that the Church may become a home for many peoples, a mother for all peoples, and that the way may be opened to the birth of a new world. It is the Risen Christ who tells us, with a power that fills us with confidence and unshakeable hope: “Behold, I make all things new” (Rev 21:5). With Mary we advance confidently towards the fulfilment of this promise, and to her we pray:

Freedom

Can. 218 Those who are engaged in fields of sacred study have a just freedom to research matters in which they are expert and to express themselves prudently concerning them, with due allegiance to the magisterium of the Church.
