This pic is is of Okover stream, which runs through the campus forms a super
beautiful core of a very pretty campus (although some of the interior
designers were quite fond of bare concrete). It also runs past the organic
community garden on campus (where there was a delicious organic BBQ today
for one dollar) which is also really really neat. Just thought I'd post a
bit about the uni and my papers (courses), since this is study abroad and
because today i finally got my enrollment all straightened out (hopefully,
enrollment is a difficult process). First off, NZ courses usually meet only
two hours a week (for lecture, then there is usually a tutorial of one hour
and sometimes a lab) and seem to run any which time on any particular day in
any particular lecture theater. This can make for a bit of an erratic
schedule - but the real advantage is that Friday classes can be avoided
fairly easily, which is a timetable that I am really enjoying. I got lucky,
as I am in four classes that count for requirements at home, are at good
times, and that have good lecturers (professor is apparently a title that is
seldom bestowed upon mere mortals here, so lecturers are just called by
their first or last names) and are interesting. My papers are:
Algebra&Cryptography (think code breaking - it's always interesting to hear
a lecturer talk about 'the enemy'), Perspectives on Maths (oh yeah, 'math'
is a plural here - this course is a history of maths with a little bit of
philosophy of maths thrown in at the end), Human Computer Interaction (the
basics of designing computer programs that people can actually use - aka
programing good GUIs using java), and Intro to NZ Politics (this should be
very interesting as NZ has plenty of unique quirks and a pretty volatile
political system - plus I know little to nothing, so there will be a heaps
of looking things/people/events up on wikipedia). Just finish up with a
couple of great things: 1) no books to buy for the semester, as the library
has a couple of copies of each of the books for my courses on three hour
loan. 2) the library has heaps of beanbags to read on. 3) it is completely
socially acceptable to walk on and around campus barefoot (to the library,
class, the student union - or to the bank, the dairy, or the grocery store)
and students (including me today) take full advantage of it.
It's amazing to think that a modern Smartphone, which is really a hand-held computer, has almost infinitely more computing power than was available to the Allies during WW2 at Bletchley Park

Normal daily life along a different timeline - which we cannot find - but have the feeling that it exists - but
Certainly!
Quantum computing represents a groundbreaking advancement in technology, deeply intertwined with the concepts of superposition, entanglement, and interference from quantum physics. Unlike classical computing, which processes information in a linear fashion using bits (0s and 1s), quantum computing utilizes quantum bits or qubits that can exist in multiple states simultaneously. This enables quantum computers to perform numerous calculations at once, effectively navigating through a vast landscape of potential solutions.
The idea of parallel timelines can be likened to the way quantum computers operate. Each decision or computation can be viewed as branching into multiple outcomes, similar to how different timelines might unfold based on various choices. This means that a quantum computer can explore various paths to a solution simultaneously, leading to remarkable efficiencies in solving complex problems.
In practical terms, this capability could revolutionize fields such as cryptography, where quantum computers may break existing encryption methods faster than classical computers. In material science, they could simulate quantum phenomena to discover new materials with desirable properties. Additionally, in optimization problems across various industries, quantum computing offers the potential to find the most efficient solutions more rapidly than traditional methods.
In summary, the link between quantum computing and the concept of parallel timelines highlights a fascinating intersection of technology and theoretical physics, suggesting that our understanding of reality may be more complex and interconnected than we previously imagined.
"Codes & Clowns" was an exhibtion devoted to Claude Elwood Shannon (April 30, 1916 – February 24, 2001) who was an American mathematician and electronic engineer known as "the father of information theory" and cryptography.

Met de opkomst van de cryptocurrency Bitcoin kwam ook de revolutionaire technologie in beeld; de blockchain. FIBER en de Brakke Grond presenteren een avond met de Vlaamse cyberfilosoof Michel Bauwens over de blockchain. Een gedecentraliseerde database die de basis vormt achter de controversiële Bitcoin.

This sigil from medieval magic was thought to be a summation of all the cosmology and numerology known in the West. It required knowledge of geometry, astronomy, astrology, mathematics, science, cryptography and more. And I've drawn it. Unfortunately, this doesn't make me any more scientifically literate in today's terms than when I began. This is kind of like being a teacher in the 21st century who doesn't know anything about computers: doing the same old stuff doesn't help your students move forward. It just perpetuates old paradigms.
This is an image of fol. 1r from University of Pennsylvania LJS 225: Litterarum simulationis liber, by Zopello, Michael, from Rome?, dated to between 1455 and 1458.
LJS 225 is a presentation copy for Pope Callistus III of a work on cryptography that describes two systems: in the first, Italian words beginning with one letter are all represented by Italian words beginning with another letter; in the second, signs or symbols represent letters or entire Italian words (titles, city names, and numbers).

Colossus did much the same as the Heath Robinson machine but was faster and more reliable, thanks to a greater use of electronics: the Mk II version had 2500 valves! This, again, is a modern replica (though using the same valves); it consumes about 8kW, and this is one of the significant costs of running the museum!
The TSEC/KL-7 was an off-line non-reciprocal rotor encryption machine. The KL-7 had rotors to encrypt the text, most of which moved in a complex pattern, controlled by notched rings. The non-moving rotor was in fourth from the left of the stack. The KL-7 with 12 rotors also encrypted the message indicator and was code named ADONIS.
