Circadian light filter: add-on for your PC or MAC

Goodmorning all,
we hope you had slept well last night!
Maybe it could be better, we know it, but now just a question: “at what time did you switch off pc/mac/tablet/smartphone and you started looking some non-blue-light-emitting surface?”

Many are sceptics and think this “belief” of Circadian rhythm and blue lights are things for scientists or just a new business. But this is not!
Blue-light-emitting surfaces are actually affecting our hormone production. In particular, this kind of lights are unbalancing our production boosting cortisol hormone and suppressing melatonin.
These two hormones are the so-called antagonist, so one suppresses the effect of the other and their secretion is rhythmically driven in quantity by the brain.

  • Cortisol is the hormone which keeps you alerted, reactive and sometimes if present in too high quantities: stressed!

  • Melatonin has both a soporific effect and an ability to catch the sleep-wake rhythm. Melatonin treatment has been reported to be effective in the treatment of disorders such as jet lag and delayed sleep phase syndrome.

In this post we suggest to install onto your pc/mac/tablets/smartphones the following add-on software which it will help you to mitigate this unbalance effects. The blogger did it with very satisfactory results.

This software name is: f.lux




picture #1:  f.lux logo

f.lux is a cross-platform computer program that adjusts a display’s colour temperature according to location and time of day. The program was designed to reduce eye strain during night-time use and reduce disruption of sleep patterns.

f.lux proponents hypothesize that altering the colour temperature of a display to reduce the prominence of white–blue light at night will improve the effectiveness of sleep. This software is totally free: important to say!




Picture #2: half of the screen filtered with f.lux and half not


Reducing exposure to blue light at night time has been linked to increased melatonin secretion and better sleep quality.
Although the developer provides a list of relevant research on their website, the program itself has not been scientifically tested to determine its efficacy.
In spite of this, f.lux has been widely and positively reviewed by technology journalists, bloggers, and users.

Have a try on it, it doesn’t cost a dime and won’t harm your computer, it will help you instead to reach your bed more relaxed and ready to sleep!

Picture #3: clicking on the small icon on the taskbar you will be able to have a look onto your supposed cortisol-melatonin balance during the day.

Blue lights simply delay your natural sleep-time!
Today is possible to preview the side effects of this exposure calculating it on the basis of data such as:

  • date

  • time of the day

  • age

  • distance from the screen

  • type of light source

You have here different blue-light quantities present in the normal daylight cycle, in an electronic device screen and in a candle.

The same software producer, give you the possibility to meter the blue-light emitted from your device, have yourself a look here:!id=lights/candle&age=35

for further information about the subject, you can refer to another desk study done on Circadian rhythm done in this blog.



and goodnight !

Daylighting Temple

This is a fantastic service that the Columbia University of New York gives out freely for everybody:
a panoramic 360° sequence of images of some very interesting and peculiar architectures.

Not anybody has had the possibility to travel so far away, and for some of us, this is the only chance to experience in an augmented reality space. I need to say that it is amazing if you can project this 360° images on a white wall and watch them in a sufficiently big scale to feel yourself in this place. It is a good approximation of reality.

This time we are having a look at a “daylighting temple” the Notre-Dame-Du-Haut , built in Ronchamp (1950-54) by the Swiss architect Le Corbusier.
Its plasticity and space conception is underlined by the use of natural light and wall thickness, masses and voids which alternatively bumps in and out the original volume of the temple.
Almost everywhere in the world, you will find buildings inspired by this one. We architects have studied every corner (better to say in this case: every bend) of this temple.

The dark side of light: how artificial lighting is harming the natural world

The world is lit at night like never before, and ecologists are assessing the damage.

It’s a summer night near a forest lake in Germany and something unnatural is going on. Beyond the dark waters lapping at the shores, a faint glow emanates from rings of light hovering above the surface. Nearby, bobbing red torchlights — the least-disruptive part of the visible spectrum — betray the presence of scientists on the shoreline. They are testing what happens when they rob the lake creatures of their night.

Do you know what is a TEDMED?
TED (Technology, Entertainment, Design) is a media organization which posts talks online for free distribution, under the slogan “ideas worth spreading”. TED was founded in February 1984 as a conference, which has been held annually since 1990. TED’s early emphasis was technology and design, consistent with its Silicon Valley origins, but it has since broadened its focus to include talks on many scientific, cultural, and academic topics.
(source Wikipedia)

TEDMED is a talk focused instead on medicine.

Mariana Figueiro, Light and Health Program Director at the Lighting Research Center (LRC) and Professor at Rensselaer Polytechnic Institute, reveals surprising facts about the effects of light – its presence, its absence, and its patterns – on human health.

Presented by Lighting Research Center scientists Dr. Mark Rea and Dr. Mariana Figueiro on March 15, 2017, this webinar addresses the American Medical Association (AMA) report cautioning the public about the use of In-Ga-N based LEDs. This webinar provides: practical, scientific advice to address the issues raised in the AMA report; direction on correctly and accurately measuring and specifying indoor and outdoor lighting; and guidance to address the problems of misapplying short-hand metrics to the topic of the health and environmental impacts of light and lighting. Thank you to the participants at more than 200 locations around the world who took part in this webinar!

The word “photography” was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), “light” and γραφή (graphé) “representation by means of lines” or “drawing”, together meaning “drawing with light”.

Several people may have coined the same new term from these roots independently. Hercules Florence, a French painter and inventor living in Campinas, Brazil, used the French form of the word, photographie, in private notes which a Brazilian historian believes were written in 1834. 

Johann von Maedler, a Berlin astronomer, is credited in a 1932 German history of photography as having used it in an article published on 25 February 1839 in the German newspaper Vossische Zeitung. Both of these claims are now widely reported but apparently neither has ever been independently confirmed as beyond reasonable doubt. Credit has traditionally been given to Sir John Herschel both for coining the word and for introducing it to the public. His uses of it in private correspondence prior to 25 February 1839 and at his Royal Society lecture on the subject in London on 14 March 1839 have long been amply documented and accepted as settled facts.

Book of thoughts

Because beauty consits of it’s own passing, just as we reach for it. It’s the ephemeral configuration of things in the moment, when you can see both their movement and their death.

Muriel Barbery, “The Elegance of the Hedgehog”




Francesco Venezia – Etruscans – Exhibition – photo by Fulvio Orsenigo

I remember this lesson of architecture as if it were yesterday, it was 2003, first year of faculty, I knew already from the first days I took a very thrilling path for my life choosing that field, I felt so fulfilled starting those studies. I felt that Architecture was an exciting mix of science, trends, materials, theory of art, daily practice, drawing, economy and management, sociology, psychology, perception and above all there was, on the very top: your vision of the world.

I was questioned about a solution for somebody’s needs. I was asked to improve life quality for people around me.

My previous year of studies in International Politics had been quite disappointing, I had the feeling that studying was a challenge in between pupil and professor to reach the highest knowledge of what professor oneself wrote: quite impossible to have a debate, very often was a stupid effort of stocking data in my mind, collect, collect and again collect. Who cares what you were really thinking about the world? Nobody cared. That was highly frustrating, indeed.


That day I remember I had a bursting shiver listening at my professor of the times:  Mr. Franciosini. I’m sure not only me, but most of my colleagues had the epiphany: “this is what I want to do in my life”.


The architect was explaining us what was the essence of our job, what was creating a “space” from nothing. In this picture it’s illustrated one of the points: a sudden expansion of spaces, this truncated pyramid aiming at an above height, a central focus of interest under the upcoming light, corridor in the darkness and subject into the light, the rate in between voids and built area.  In few words: a theatre.



“All the variety, all the charm, all the beauty of life is made up of light and shadow.”

Leo Tolstoy, “Anna Karenina”



Se puderes olhar, vê. Se podes ver, repara.
Dom Duarte, “Livro dos conselhos”


Dentro de nós há uma coisa que não tem nome, essa coisa é o que somos.

É que vocês não sabem, não o podem saber, o que é ter olhos num mundo de cegos.

Costuma-se até dizer que não há cegueiras, mas cegos, quando a experiência dos tempos não tem feito outra coisa que dizer-nos que não há cegos, mas cegueiras.

Por que foi que cegámos, Não sei, talvez um dia se chegue a conhecer a razão, Queres que te diga o que penso, Diz, Penso que não cegámos, penso que estamos cegos, Cegos que vêem, Cegos que, vendo, não vêem.

José Saramago, “Ensaio sobre a cegueira”
