Leonardo da Vinci (1452 - 1519)

Leonardo nasceu a 15 de Abril de 1452, na pequena cidade de Vinci, perto de Florença, centro intelectual e científico da Itália. O seu talento artístico cedo se revelou, mostrando excepcional habilidade na geometria, na música e na expressão artística. Reconhecendo estas suas capacidades, o seu pai, Ser Piero da Vinci, mostrou os desenhos do filho a Andrea del Verrocchio. O grande mestre da renascença ficou encantado com o talento de Leonardo e tornou-o seu aprendiz. Em 1472, com apenas vinte anos, Leonardo associa-se ao núcleo de pintores de Florença.



Não se sabe muito mais acerca da educação e formação do artista, no entanto, muitos autores afirmam que o seu conhecimento não provém de fontes tradicionais, mas sim da observação pessoal e da aplicação prática das suas ideias.



Pintor, escultor, arquitecto e engenheiro, Leonardo da Vinci foi o talento mais versátil da Itália do Renascimento. Os seus desenhos, combinando uma precisão científica com um grande poder imaginativo, reflectem a enorme vastidão dos seus interesses, que iam desde a biologia, à fisiologia, à hidráulica, à aeronáutica e à matemática.

Möbius strip

The Möbius strip or Möbius band (alternatively written Mobius or Moebius in English) is a surface with only one side and only one boundary component. The Möbius strip has the mathematical property of being non-orientable. It is also a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.


A model can easily be created by taking a paper strip and giving it a half-twist, and then joining the ends of the strip together to form a loop. In Euclidean space there are in fact two types of Möbius strips depending on the direction of the half-twist: clockwise and counterclockwise. The Möbius strip is therefore chiral, which is to say that it has "handedness" (as in right-handed or left-handed).

As aparências iludem...

Dr. Phil suggests keeping the following points in mind when you're talking to someone who you think might be stretching the truth:
1) Too much or too little eye contact. Liars tend to avoid looking people in the eye, but if they are staring you down, they may be working hard at lying.
2) Over-emphasizes details. When people are trying to avoid telling the truth, they often pick some obscure point and talk about it a lot instead of focusing on the key issue.
3) Fidgeting. Is the person you're talking to very fidgety? You often see kids do this when they're telling a tale. That's a sign that someone may be lying.
4) Touching nose. Research shows that when people lie, they tend to touch the base of their nose a lot.
5) Mouth pursed. When people tell a lie, they can't get enough oxygen, so they tend to breathe through their mouth instead of through their nose.
6) Speech hesitations. Pausing, throat clearing, or other stalling techniques may indicate that a person is embellishing the truth.
7) Looking up or down. They may be stalling for time.
8) Answers questions not asked. Without even asking them a question, liars will defend themselves.
9) Other body language to check for to spot a potential liar include: excessive blinking, dilated pupils, pitch changes, less smiling, and shrugging shoulders.

This Is The Last Time (Keane)

This is the last time
That I will say these words
I remember the first time
The first of many lies
Sweep it into the corner
Or hide it under the bed
Say these things, they go away
But they never do

Something I wasn't sure of
But I was in the middle of
Something I forget now
But I've seen too little of

(Chorus)
The last time
You fall on me for anything you like
Your one last lie
You fall on me for anything you like
And years make everything alright
You fall on me for anything you like
And I, no I don't mind

This is the last time
That I will show my face
One last tender lie
And then I'm out of this place
Tread it into the carpet
Or hide it under the stairs
You say that some things never die
Well I tried and I tried

Something I wasn't sure of
But I was in the middle of
Something I forget now
But I've seen too little of

The last time
You fall on me for anything you like
Your one last lie
You fall on me for anything you like
And years make everything alright
You fall on me for anything you like
And I, no I don't mind

(Instrumental Break)

The last time
You fall on me for anything you like
Your one last lie
You fall on me for anything you like
And years make everything alright
You fall on me for anything you like
And I, no I don't mind

Viva la vida (Coldplay)

I used to rule the world
Seas would rise when I gave the word
Now in the morning I sleep alone
Sweep the streets I used to own

I used to roll the dice
Feel the fear in my enemy's eyes
Listen as the crowd would sing:
"Now the old king is dead! Long live the king!"
One minute I held the key
Next the walls were closed on me
And I discovered that my castles stand
Upon pillars of salt, pillars of sand

I hear Jerusalem bells are ringing
Roman Cavalry choirs are singing
Be my mirror my sword and shield
My missionaries in a foreign field
For some reason I can not explain
Once you know there was never, never an honest word
That was when I ruled the world
(Ohhh)

It was the wicked and wild wind
Blew down the doors to let me in.
Shattered windows and the sound of drums
People could not believe what I'd become
Revolutionaries Wait
For my head on a silver plate
Just a puppet on a lonely string
Oh who would ever want to be king?
