The Internet is an amalgam of forms blurred under epistemological pressures. In Søren Kierkegaard’s words, under this flat shower of leveled information, where everybody is interested in everything and nothing is too trivial or too important, people just accumulate information and postpone decisions indefinitely, i.e., nobody takes action and nobody is responsible for truth — there is no mastery, just gossip. He called this the æsthetic sphere of existence, exhorting us to evolve to the ethical sphere, where we do not just accumulate information but take action and make commitments. Blogs are instruments to overcome flatness by creating opportunities for vertical activities. In this sense this blog is a view from my window — a collection of tidbits I judged relevant to computational color science and in general to the promotion of scientific excellence in areas of strategic importance for the future of research, economy and society.

» The mistery of stable images

We know optically the eye is like a simple meniscus camera that projects an image onto the retina. We also know that on the cortex there is a holomorphic map of the visual field. However we know very little of what happens in between. For example, in the lateral geniculate nucleus (LGN) there are seven layers, and if we stick a toothpick in a point like in a club sandwich, the layers are geometrically aligned.

» Promoting happiness

Last December I wrote a short post about a Science paper providing neurophysiological evidence for the importance of social comparison on reward processing in the human brain. The last print version of Science has a paper teaching us how we can be even happier.

» Administrative note and color lawsuits

First an administrative note. Most feedback we get from you, our esteemed readers, is in the form of personal email. Only rarely are we able to generate sufficient controversy to spark a debate in the blog comment section, such as with Non-local realism, An On-Line Color Thesaurus, or yesterday's Revolutionary White Reflectance Standard for Metrology. Therefore, we are happy for every good comment we get. However, as you are aware our blog server is rather crafty, and it is difficult for us to find comments when you replace the post title with your own title. This summer HP will be upgrading to commercial blogging software and this blog will run smoother, hopefully even multilingually. In the meantime here is my answer to a comment on color lawsuits I was unable to locate.

» Revolutionary White Reflectance Standard for Metrology

Today two color scientists at HP Labs announced the introduction of a revolutionary new white reflectance standard for metrology. This new reflectance standard is a breakthrough in terms of cost, simplicity and unique environmentally friendly disposal process. This new white standard will have broad impact in the fields of photonics, digital photography and color measurement and is available for immediate commercial and research use.
