Genome Sciences Center 20th Anniversary Clothing, Music, Drinks and Art
On 15 November 2019, the Genome Sciences Center held its 20th anniversary celebration.
Here you can read about the design of the evening's clothing, music, drinks and other art.
After silence, that which comes nearest to expressing the inexpressible is music.
— Aldous Huxley
Music
We commissioned Segue to create a unique ambient music landscape for the celebration.
Segue is the name used by Jordan Sauer, an electronic music producer from Vancouver, BC. He creates ambient electronic music with layers of field recordings, acoustic and electronic sounds, creating sonic soundscapes that conjure images of nature and emotions of peace and introspection. He has release numerous solo albums and collaborations with artists from around the world, and recently released a solo album “The Island” on the Silent Season record label in summer 2019. Jordan is thrilled to partner with the GSC in the production of “Gene Machines”.
gene machines
Gene machines will be available as a digital download soon. We are also planning to have a vinyl release.
An assembly of shifting soundscapes, textures and rhythmic loops produced by the laboratory machines.
In commemoration of the 20th anniversary of Canada’s Michael Smith Genome Sciences Centre, Segue was comissioned to create an original composition based on audio recordings from the GSC’s laboratory equipment, robots and computers—to make “music” from the noise they produce.
Machine noise is a challenging palette of musical ingredients—sharp, abrasive and whirring sounds are typically unpleasant. For one night, these machines are repurposed as acoustical performers.
In the process of creating “Gene Machines”, recordings were analyzed for their specific frequency profiles and then used to generate melodic or percussive sounds. Together with bass from a Moog synthesizer, the sounds were then stretched, manipulated and sequenced into a series of compositions. Each composition is based on the recording from one specific laboratory machine, emphasizing its tone and timbre quality.

Markov models — training and evaluation of hidden Markov models
With one eye you are looking at the outside world, while with the other you are looking within yourself.
—Amedeo Modigliani
Following up with our Markov Chain column and Hidden Markov model column, this month we look at how Markov models are trained using the example of biased coin.
We introduce the concepts of forward and backward probabilities and explicitly show how they are calculated in the training process using the Baum-Welch algorithm. We also discuss the value of ensemble models and the use of pseudocounts for cases where rare observations are expected but not necessarily seen.

Genome Sciences Center 20th Anniversary Clothing, Music, Drinks and Art
Science. Timeliness. Respect.
Read about the design of the clothing, music, drinks and art for the Genome Sciences Center 20th Anniversary Celebration, held on 15 November 2019.
As part of the celebration and with the help of our engineering team, we framed 48 flow cells from the lab.
Each flow cell was accompanied by an interpretive plaque explaining the technology behind the flow cell and the sample information and sequence content.
Scientific data visualization: Aesthetic for diagrammatic clarity
The scientific process works because all its output is empirically constrained.
My chapter from The Aesthetics of Scientific Data Representation, More than Pretty Pictures, in which I discuss the principles of data visualization and connect them to the concept of "quality" introduced by Robert Pirsig in Zen and the Art of Motorcycle Maintenance.
