Mutation 

In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair (especially microhomology-mediated end joining), or cause an error during other forms of repair, or else may cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity.

Francis of Assisi

Saint Francis of Assisi (Italian: San Francesco d'Assisi), born Giovanni di Pietro di Bernardone, informally named as Francesco (1181/1182 – 3 October 1226), was an Italian Roman Catholic friar and preacher. He founded the men's Order of Friars Minor, the women’s Order of Saint Clare, the Third Order of Saint Francis and the Custody of the Holy Land. Francis is one of the most venerated religious figures in history.

Pope Gregory IX canonized Francis on 16 July 1228. Along with Saint Catherine of Siena, he was designated Patron saint of Italy. He later became associated with patronage of animals and the natural environment, and it became customary for Catholic and Anglican churches to hold ceremonies blessing animals on his feast day of 4 October

Bridge Over Troubled Water

https://www.youtube.com/watch?v=H_a46WJ1viA

When you're weary, feeling small
When tears are in your eyes, I'll dry them all (all)
I'm on your side, oh, when times get rough
And friends just can't be found
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down1

When you're down and out
When you're on the street
When evening falls so hard
I will comfort you (ooo)
I'll take your part, oh, when darkness comes
And pain is all around
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down

Sail on silver girl
Sail on by
Your time has come to shine
All your dreams are on their way
See how they shine
Oh, if you need a friend
I'm sailing right behind
Like a bridge over troubled water
I will ease your mind
Like a bridge over troubled water
I will ease your mind

The Birth of Venus

The Birth of Venus is a painting by Sandro Botticelli generally thought to have been painted in the mid 1480s. It has long been suggested that Botticelli was commissioned to paint the work by the Medici family of Florence, specifically Lorenzo di Pierfrancesco de' Medici under the influence of his cousin Lorenzo de' Medici, close patron to Botticelli. However, there are no documents associated with the painting, and its first identification with the Medici family only comes in the 1550 edition of Vasari's Lives. It depicts the goddess Venus, having emerged from the sea as an adult woman, arriving at the shore (which is related to the Venus Anadyomenemotif). The painting is on display at the Uffizi Gallery in Florence, Italy.
