Backstory: So on the Thursday before Working Weekend the Switchboard students go together to brainstorm what they wanted to plan for the big day. Their idea was to dress Brent '14 up as Gumby; hand out ringpops and pub mix; and ask students and alumni "What can you teach Gumby?" and then pin these answers onto Gumby. So that's what they did.
Huge props to Leah, Martha, Brent, Rebecca, Paul, Kieran and Alex for pulling this crazy and delightful idea off.
Here's the incredible list of things Reedies can teach:
President John Kroger: About Heidegger's Sein und Zeit
Amy Bogran '89: "How to do your taxes"
Doug Kerns (Reed Parent): "The beautiful and simple dance of electrons in silicon"
Anand Panchal '13: Hindi/Gujarati
Derek Owen '97: "How to play the first few bars of Carmina Burana on the ukulele"
Will '13" "How to love"
Anna Fimmel '16: "All about neurons"
Kristen Biers-Jones '80: "How to take a blood pressure"
Sierra: "How to long board and power slide"
Ulrich Loft '94: German, cardiology
Daniel Baggott '95: software
Karen Silbert '13: Brain surgery (not)
Anonymous: explosives
Thomas Burns '98: "How to apply for a Fulbright"
John Cushing '67: "How to play the penny whistle"
Robert Smith '89: "How to foxtrot"
Zach Brown '13: YOLO
Mark Chen '95: "How to scrounge Mt. Rushmore Visitor Center successfully"
Jennifer Jordan '89: "How to start up"
Frida Cruz: "How to make a dream machine"
This group exhibition, including work by Catherine Richards, Michael Snow, Scott Rogers, Thomson & Craighead and Simon Pope, draws on ideas of scientific experimentation, media processing, and time delay. Each work acts to slow down our senses of perception, causing within us an awareness of both time passing and our experience of it. The title refers to that fact that we often watch other people interact with responsive art, and mirror their behaviour, consciously or not.
Catherine Richards’ I was scared to death / I could have died of joy features glass replicas of the brain, which react to your presence with pulses of electromagnetic light. Scott Rogers’ Between Nonesuch Place juxtaposes an actual non-functioning glass object, a ‘self-flowing flask’ with its virtual working counterpart. Thomson & Craighead’s Flipped Clock is a modified digital clock display, where each individual digit is rotated by 180-degrees. Simon Pope’s Recall From Memory the Space of Another Gallery is an invitation for the visitor to recall experiences of being in other gallery spaces from memory. The seminal filmmaker Michael Snow’s WVLNT: Wavelength for those who don't have the time. Originally 45 minutes, Now 15! remixes his own seminal work Wavelength.

Coupe parasagittale au niveau des replis de la valvule du cervelet. La technique de coloration est la même que celle de la figure P11a_010 avec un grossissement des replis multiplié par quatre. Cette méthode à l’argent, utilisée sur coupes à la paraffine, est rapide et assez bien reproductible. Elle teinte en noir le réseau neurofibrillaire des dendrites et axones mais pas les corps cellulaires, qui présentent une teinte brun-orangé.

Parasagittal section through the folds of the valvula cerebelli. Neuronal processes can be quite easily
demonstrated in paraffin sections by using the silver
impregnation according to Tinel. This rapid and
fairly reliable method stains axons, fibrillary structures
(neurofibrils) and dendrites of many neurons in
black, with some differences depending on the procedure.
Cell bodies (somata) of neurons are in shades of orange brown.

Growing brain cells from humans to understand brain development and disease has become possible with the advent of induced pluripotent stem cell (iPSC) technology. Here, a skin biopsy is taken and the resulting skin cells grown in a dish. These cells are then reprogrammed to naive stem cells using a clever cocktail of biological factors. These stem cells are now pluripotent - meaning they can be differentiated into any cell type in the body with the appropriate instructions. In this image, human iPSCs have been instructed to make cortical brain cells, or neurons, which make up three quarters of the human brain. The red flower-like structures, known as ‘rosettes’, are labelled for a marker of neuronal stem cells. These neuronal stem cells give rise to the more mature neurons, labelled green, with their characteristic long branches. The nuclei of these cells are labelled blue. A truly remarkable process.
#deepdream code informatique de l'intelligence artificielle de Google spécifique "Fractal DDC " développé et dédié pour un nouvel art à La Demeure du Chaos - The Abode of Chaos ou comment les machines perçoivent La Demeure du Chaos - The Abode of Chaos
et si leurs regards étaient ce qui se cache derrière la matrice que nous percevons en tant qu'humains? ces multiples miroirs sont peut-être un autre monde plus réel ou plus éthéré... NB thierry bonne lecture de ce post et ses images dantesques.
Depuis quelques temps vous avez peut-être vu circuler sur les réseaux sociaux des images étranges, affublées d'un hashtag (mot-clé) #deepdream.
Deep Dream est un programme d'intelligence artificielle mis au point par les ingénieurs de Google. Ces derniers travaillent à la reconnaissance d'images pour, entre autres, améliorer la pertinence des recherches dans Google. Le 17 juin dernier ils ont publié un billet intitulé : "Inceptionnisme : plus loin dans les réseaux neuronaux".
Dans ce post ils expliquent comment ils ont réussi, dans leurs recherches, à faire analyser une image mais surtout générer des formes par l'ordinateur. Pour que l'intelligence artificielle puisse mieux reconnaître ce qui compose une image, les ingénieurs ont commencé par lui montrer des millions de photos.
Plusieurs couches de neurones
L'intelligence artificielle fonctionne ici en un ensemble de réseaux de neurones qu'il faut se figurer comme différentes couches. La première est chargée de regarder les bords et les angles d'une image.
Les couches intermédiaires cherchent quant à elles les formes et les différents éléments présents dans l'image comme une feuille ou une porte. Les derniers réseaux assemblent toutes ces informations pour en fournir des interprétations complexes, comme des arbres ou des bâtiments.
Pour comprendre au mieux comment fonctionnent ces couches, les ingénieurs ont tenté de pousser l'analyse de certaines. Ils résument ainsi la commande faite au système : "Quoi que tu vois, on veut le voir encore plus." C'est alors que l'intelligence artificielle a généré des formes au sein des clichés.
"Si un nuage ressemble un petit peu à un oiseau, alors le système va le faire ressembler encore plus à un oiseau, expliquent les ingénieurs. En réitérant l’action, le programme va reconnaître un oiseau plus fortement et ainsi de suite jusqu’à ce qu’un oiseau très détaillé apparaisse, comme sorti de nulle part."
"L'inceptionnisme"
Les images varient selon le réseau neuronal qui est amplifié. Par exemple, plus on sollicite les couches inférieures, plus des traits vont apparaître. Si on stimule d'avantage les couches supérieures, ce sont des objets qui émergent de l'image.
Les ingénieurs précisent d'ailleurs que comme l'ordinateur a enregistré beaucoup de clichés d'animaux durant son entraînement, il en reproduit souvent. Et parfois en les mixant, ce qui crée des créatures étranges.
Pour ces chercheurs, le Deep Dream a ainsi créé un mouvement artistique qu'ils appellent "l'#inceptionnisme", en référence à l'architecture des réseaux neuronaux.
Au début, cette expérimentation ne cherchait qu'à améliorer l'intelligence artificielle. Mais lorsque les ingénieurs ont posté ce billet, de nombreux internautes se sont intéressés à ce Deep Dream.
Google a donc rendu public le code utilisé pour générer ces images. Des informaticiens s'en sont emparés et ont mis au point des logiciels et des interfaces pour que les internautes puissent s'en servir.
Ce qui ne manque pas de plaire à Google. Les chercheurs encouragent à taguer les images #deepdream sur Twitter, Facebook ou Google+. "Il sera intéressant de voir quelles images les gens arrivent à générer", écrivent-ils.
By activating multiple fluorescent proteins in neurons, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering their cells in a riotous spray of colors dubbed a "Brainbow";
Brainbow allows researchers to tag neurons with roughly 90 distinct colors, a huge leap over the mere handful of shades possible with current fluorescent labeling. By permitting visual resolution of individual brightly colored neurons, this increase should greatly help scientists in charting the circuitry of the brain and nervous system.

allora il flickeriano-mezzo-neurone, che ha deciso di contribuire affinché la mia anima vada in Paradiso senza passare dal Purgatorio, e, anzi lotta perché io sia direttamente fatta santa, mi fa:
- ma te perché non usi una reflex?
io, che sono buona, non lo mando direttamente all'Inferno (anche se così avremmo buone possibilità di smettere di sentirci, ma vabbè...) e gli rispondo, con tutta la calma possibile:
- vedi, io non uso la reflex perchè non ho una reflex.
io ho due compattine.
una, ormai famosa su Flickr, che si chiama Zoran, ma è una storia lunga e non vorrei tediarti;
la seconda si chiama Fujina, ed è quella che uso di più, adesso, perchè la Zoran è un po' malaticcia, da quella volta che ha preso un'onda sulla faccia e io non sono riuscita a salvarla in tempo, neanche pulendola con amore col maglione di lana.
ah, ti capitasse che un'ondata ti prende la compattina, non usare la maglia di lana, e non cercare neanche di asciugarla con il fon ( o phon): non funziona.
comunque, a parte questo "parco-macchine", avrei voglia di comperarmi la numero tre.
sai, flickeriano-mezzo-neurone, ci sto lavorando sopra.
ho letto un miliardo di pagine, consultato link, adesso so un sacco di cose che prima non sapevo neanche esistessero.
chessoio:
cose tipo ISO, pixel, rumore;
ho scoperto che esistono le compattone anche dette bridge;
che se in una macchina ci sono cento milioni di pixel ma un'apertura piccola è come cercare di fare entrare me in una taglia 42:
praticamente un casino, i pixel ti sbottano da tutte le parti, come la mia ciccia, e viene fuori il "rumore" (nel mio caso i rotolini);
ho scoperto anche che ci sono compattone che pesano come le reflex, però hanno tutto:
tele, zoom ottico, cento milioni di pixel e se vai nella modality "casalinga" trovi anche l'opzione "tagliatelle" e "frittura mista".
nel senso che ci puoi anche impastare le uova e cucinare il pesce, con le compattone, ma hanno sempre quel ca**o di rumore, e non si sa come toglierlo.
che poi non è vero, c'è un programma che toglie il "rumore", però poi non ho capito come si usa, ma vabbè.
vedi, flickeriano-mezzo-neurone, io prima prendevo le fotocamere così, a intuito.
tipo:
"caruccia questa, fa pendant con la la mia borsetta e posso anche abbinarla con gli anfibi e il poncho"
da quando ho cominciato a leggere e studiare le macchine fotografiche mi sembra di sapere un sacco di cose teoriche, (a parte quella cosa f.1/8 o roba simile, che non ho bn capito a cosa serva...).
in compenso non ho ancora capito:
a) come ca**o abbia fatto a fare fotografie fino adesso con le mie compattine, perché la Zoran, per esempio, non viene neanche catalogata: ho una fotocamera fantasma;
b) come ca**o abbia fatto a vivere fino a ora senza un tele, un grandangolo e un aggeggio con meno di un miliardo mi pixel;
però ho capito che:
a) le reflex sono costose, se non sono costose sono ciofeche, i kit sono ciofeche, e comunque io sono troppo ignorante per una reflex;
b) mi piacerebbe una compattona ma pesa 7 etti e allora mi tocca anche cambiare tutto il mio parco-borse, perchè non ne ho di così capienti da portarmi dietro 7 etti di macchina E tutto il resto;
c) secondo me cascherò nel solito ingranaggio e comprerò una fotocamera carina, con i fiorellini applicati sopra;
d) chissà a cosa serve quell' f.1/8 o f1.8 o cose così...
e tu, flickeriano-mezzo-neurone, che fotocamera hai?

Onkologie
Was hier wie ein Halsreif aussieht, entpuppt sich im Blick der Wissenschaft als die Schleife, durch die es den Zellausläufern gelingt, zu dem grünen Wachstumskegel zurückzukehren, dem sie entwachsen sind. Lange Ausläufer dieser Art bringen nur Nervenzellen zustande, und sie verlieren diese Fähigkeit nicht, wenn sie aus der natürlichen Umgebung genommen und in die Kulturschale gebracht werden. Gelungen ist die Aufnahme mit einem Fluoreszenzmikroskop, mit dessen Hilfe die Wissenschaftler vor allem nach Faktoren suchen, die das Wachsen entarten und gefährlich werden lassen.
