Eye Glasses (Invention History)


Eye Glasses Important Firsts:
  • Salvino D'Armate, from Italy, is credited with inventing the first wearable eye glasses around 1284.
  • The first pictorial evidence for eyeglasses comes from the portrait of cardinal Hugh de Provence reading in a scriptorium, painted by Tomaso da Modena in 1352 (see portrait detail, right).
Eye Glasses Historical Notes:
  • Francesco Redi, in 1676 wrote that he possessed a 1289 manuscript whose author complains that he would have been unable to read or write if it were not for the recent invention of glasses.
  • Francesco Redi also wrote that he had the record of a sermon given in 1305, in which a Dominican monk, Fra Giordano da Rivalto, claimed that glasses had been invented less than 20 years previously.
  • Although the inventor may always be disputed, it is certain that eye glasses were invented in Italy between 1280 & 1300.
Early Spectacles:
  • These were initially convex lenses that corrected both hyperopia (farsightedness), & the presbyopia (aging related).
  • The concave lens was discovered later by Nicholas of Cusa and found to be useful in the treatment of myopia (nearsightedness).
Eye Glasses Other Facts:
  • The provision of spectacles will certainly have helped in maintaining scholarship amongst the aging academics, theologians, philosophers of the late middle-ages.
  • Johannes Kepler, in his treatise on optics and astronomy (published in 1604), described the first correct explanation as to why convex and concave lenses could correct hyperopia-presbyopia & myopia respectively.

Sirventes or Serventes (Lyric Poetry Genre)

Important Facts:
  • Sirventes or serventes (Mistralian norm sirventès).
  • It is a genre of Occitan lyric poetry.
  • This type of poetry was used by the Provençal troubadours in particular.
  • It usually was written from the perspective of a paid servant (sirven) or soldier.
  • The verses were moral or religious in content, and always partisan, whether complimentary or vitriolic in their satire of social vices.
Troubadour Exponents:
  • Bertran de Born (ca. 1180–1200) was a famous exponent of this poetic style.
  • Peire Cardenal was another writer of sirventes in the 13th century.
  • The word sirventes was first applied to a text, ca. 1150, by the minor Gascon troubadour Marcoat.
  • Peire Lunel de Montech in 1348 composed the sorrowful sirventes "Meravilhar no·s devo pas las gens" during the Black Death in Toulouse, France.

A Farewell (Poem by Alfred, Lord Tennyson)


A Farewell - Analysis:
  • The narrator is writing about a small rivulet which he knows well but will not visit again in the future.
  • The poem is taken to mean that the narrator is thinking about his own death.
  • There is a contrasting of the potentially eternal presence of the rivulet with his own limited time on this earth.
  • There is also the comparison of his life fading away, as the rivulet fades into a river, and eventually the sea.
  • By using the nature theme, Tennyson is reminding us of how small we really are compared with the world & the universe.
  • The line “not by thee my steps shall be” is said so very matter-of-factly, that it suggests there is no regret by the narrator, for he has lived a good life.

A Farewell


Flow down, cold rivulet, to the sea,
Thy tribute wave deliver:
No more by thee my steps shall be,
For ever and for ever.

Flow, softly flow, by lawn and lea,
A rivulet then a river;
No where by thee my steps shall be,
For ever and for ever.

But here will sigh thine alder tree,
And here thine aspen shiver;
And here by thee will hum the bee,
For ever and for ever.

A thousand suns will stream on thee,
A thousand moons will quiver;
But not by thee my steps shall be,
For ever and for ever.

by Alfred, Lord Tennyson

Hunthagon = 100000 Sided Polygon (New Word, Trigonometry)


Alchemipedia announces a new word - HUNTHAGON.

A HUNTHAGON is a 100,000 sided polygon.

The word is derived from the word Hunth meaning 100,000.

A regular hunthagon is a very close approximation of a circle.

Marine Mucilage and Marine Snow (Marine Biology)


Marine Mucilage Definitions:
  • Marine snow - small amorphous aggregates with colloidal properties.
  • Marine Mucilage - coalescence of marine snow into large marine aggregates.
Marine Mucilage Background Information:
  • Marine snow is present in all oceans of the world.
  • Surface water warming can favour the coalescence of this marine snow into marine mucilage.
  • Marine mucilage characteristic of aquatic ecosystems with changed environmental conditions.
  • The phenomenon is causing increased concern around coastal areas as a result of socio-economical consequences.
  • The Adriatic Sea (esp. Northern portion) within the Mediterranean basin is the most severely affected by outbreaks of massive marine mucilage.
  • Research evidence suggests that spreading of mucilage in the Mediterranean Sea is linked to climate-driven sea surface warming.
Marine Mucilage History:
  • Mucilage was reported in the Adriatic Sea for the first time in 1729.
  • The original description mentioned the “dirty sea” phenomenon (“mare sporco”) as it caused the clogging up of fishing nets.
  • From this time there have been sporadic reports of the phenomenon.
  • Over the last 30 years, the reported frequency of this phenomenon appears to have increased markedly.
Marine Mucilage Composition:
  • Made of exopolymeric compounds with highly colloidal properties that are released by marine organisms.
  • Phytoplankton will exude photosyntetically-derived carbohydrates when placed in stressful conditions (i.e. P-limited diatoms which produce large amounts of polysaccharides, or death & decomposition of cell-wall debris).
  • Prokaryotes may not be able to digest these exopolymers leading to release and further accumulation.
Marine Mucilage Consequences:
  • The mucilage makes seawater areas unsuitable for bathing because of the bad smell & the adherence to the skin of bathers.
  • The life span of the mucilage may be up to 2-3 months on the water surface or column.
  • Marine mucilage once it has settled on the sea bottom, coats the sediments, & may extend for kilometers - producing hypoxic / anoxic conditions.
  • This may then cause suffocation of benthic (bottom-associated) organisms.
  • The mucilage can also act as major repository for prokaryotes (i.e.bacteraia & protozoa) & viruses with the potential health risks of this.
  • Fingerprinting techniques also show that the mucilage has increased bacterial diversity compared with the surrounding seawater.
  • Fluorescence in situ hybridization (FISH) has identified Vibrio harveyi in from some marine mucilage deposits, but not in the surrounding seawater.
  • It is possible that the complex organic matrix of marine mucilage enables favourable microniches to develop which then support pathogen colonization & survival.
