Maya


Mayan writing system was essentially phonetic, although glyphs could also be used to express morphemes (the smallest unit of meaning) and phonetic signs could be added to morphemes for clarity

Steady wave along ship side



Bit odd at the stern but it's the best I obtained till now

A Numbered Story

One upon a time, in a country named 1764, it was living Seven closely watched by Six.

At a certain moment, annoyed by Six, Seven yielded to him: "Be 7!"

Six replied: "You mean 6, 7?!"

After some while reflections, Seven committed Four.

The Seven

Seven cannot be perceived,

six is the last to be taken into account.



Between six and Seven it's an abyssus

like between rational and Irrational.

Thoughts

When you read and think about this it will be in my past.

No one can reach my actual thinking, the entire world is thrown in the past.



Which are the actual connections between men, between men and nature in general?

Are verbal, factual, sensitive, emotional connections.



But thinking cannot be catched in the instant nor in the future.

Thinking is singular, it makes us unique.



Only God actually knows our thoughts.

Analysis of the flow around the Hanse cog



The computation for meshing the Hanse cog (including the rough fairing of the hull) was done in one week.

It will be interesting to study the steady and unsteady flow around this aged hull form. The conclusions and some pictures will be added to the blog. Maybe I'll publish the results in a Naval Architecture journal.

Bodylines and mesh for a Hanse Cog

Some time ago I found a paper on Internet about an ancient ship.



H. Brandt, K. Hochkirch [TU Berlin Institute of Naval Architecture, Marine and Ocean Engineering (ISM), TU Berlin] Ship Technology Research Vol. 42, No. 1, January 1995:



"A Hanse cog was discovered during dredging work in the port of Bremen in 1962. The cog's construction was dated to the year 1380 by means of dendrochronological analysis. Until this finding was made, virtually nothing was known about the shape and rigging of Hanse cogs. The sole source for information on their appearance had been illustrations on seal impressions, which provide only an approximate idea. Accounts of possible travelling speeds vary greatly, i.e. between 3.3 and 10 knots; data on weather conditions and wind directions are completely absent from reports.
