Desiderata

"Go placidly amid the noise and haste,

and remember what peace there may be in silence.
As far as possible, without surrender,
be on good terms with all persons.
Speak your truth quietly and clearly;
and listen to others,
even to the dull and ignorant;
they too have their story.
Avoid loud and aggressive persons;
they are vexations to the spirit.
If you compare yourself with others,
you may become vain or bitter,
for always there will be greater
and lesser persons than yourself.
Enjoy your achievements as well as your plans.
Keep interested in your own career, however humble,
it's a real possession in the changing fortunes of time.
Exercise caution in your business affairs,
for the world is full of trickery.
But let this not blind you to what virtue there is;
many persons strive for high ideals,
and everywhere life is full of heroism.
Be yourself.
Especially do not feign affection.
Neither be cynical about love;
for in the face of all aridity and disenchantment,
it is as perennial as the grass.
Take kindly the counsel of the years,
gracefully surrendering the things of youth.
Nurture strength of spirit
to shield you in sudden misfortune.
But do not distress yourself with dark imaginings.
Many fears are born of fatigue and loneliness.
Beyond a wholesome discipline,
be gentle with yourself.
You are a child of the universe
no less than the trees and the stars;
you have a right to be here.
And whether or not it is clear to you,
no doubt the universe is unfolding as it should.
Therefore be at peace with God,
whatever you conceive him to be.
And whatever your labors and aspirations,
in the noisy confusion of life,
keep peace in your soul.
With all its sham, drudgery and broken dreams,
it is still a beautiful world.
Be cheerful.

Strive to be happy".

Pi day (3-14-15 = 14th of march of 2015)

Con motivo de la celebración del día de Pi (14 de marzo de 2015 en EEUU se escribe 3-14-15 que es una aproximación por truncamiento a las diezmilésimas del número pi), mis alumnos realizaron una serie de tareas relacionadas con el famoso número irracional. Aquí os cuelgo algunas de ellas (las presentaciones en powerpoint han sido expuestas en clase por lo que aquí se muestran de forma esquemática):

Video  acerca de la presencia de pi en series y películas:

Presentación sobre la aparición del número Pi y el número áureo en la naturaleza: 

Presentación sobre la presencia de pi en la sociedad:

HEY are rattling breakfast plates in basement kitchens,

And along the trampled edges of the street

I am aware of the damp souls of housemaids

Sprouting despondently at area gates.

 

The brown waves of fog toss up to me

Twisted faces from the bottom of the street,

And tear from a passer-by with muddy skirts

An aimless smile that hovers in the air

And vanishes along the level of the roofs.

T.S. Elliot.
