I had an epiphany of sorts in the first year of my career. In fact, I had quite a few revelations as I learned what wasn’t taught in three levels of education. In my first office job, I was being taught practical things by Dalziel, a phonetically correct abbreviation for a very tolerant teacher. I asked how to calculate the length of a geophysical profile and his answer was to ‘count the posts not the gaps’. A few days later, I asked him to explain what ‘mistie’ meant. I pronounced it misty. He laughed and said ‘put a metaphorical hyphen in it’. I was learning about seismic recording techniques from a man who did the Daily Telegraph crossword in twenty or thirty minutes every day while enjoying a pint (or two) of plain and a toasted cheese sandwich (or two) in a Dublin pub. In the realms of onshore geophysics, the listening devices are arrays of geophones, centred on ‘stations’. A billable length, like a fence, is the distance between two stations or posts. Sometimes, for reasons due the geometry of echoes from sloping subsurfaces, two readings might mistie due group azimuth or line bearing.[Read more…] about Posts and Gaps
Where are all the Curies?
In a normal world, there are people who study deviations beyond the standard. There’s a conventional heuristic (rule of thumb) that our most significant interests fall within three standard deviations from the meanest of any measure.
I journaled here of a corporate presentation I titled ‘To 3σ and Beyond’. That, together with the opening paragraph today, are (bad) statistics-based jokes intended to refer to new learnings that may lurk within less than 6.7% of a range of products or data.[Read more…] about Where are all the Curies?
We heard the siren call of the seals this afternoon. Pod, rookery or harem, there were upwards of a dozen of the pinnipeds basking in the diffuse light on rocks exposed by a very low tide.
It was befitting of Bloom’s Day to see the seals in Sandycove where James Joyce spent six nights in 1904. ‘A sleek brown head, a seal’s, far out on the water, round’ was his description of Buck Mulligan in Ulysses. Could this have been inspired by the Sandycove ancestors of these seals?[Read more…] about Ignobility Index
