AI Thread Summary
Cracovians are identified as matrices that require braces for enclosure, reflecting their function in early computing when tapes were utilized for memory storage. The discussion highlights the ambiguity surrounding their operational mechanics. A reference to a visual representation is provided, suggesting a connection to mathematical equations. The mention of a link to a 1942 publication implies a historical context and deeper exploration of their significance. Understanding Cracovians may offer insights into foundational computing concepts.

Cracovians seem to be matrices. I'm looking at some right now, but how they operate is not clear. Braces are used to enclose them. jpg shows the idea.

They belong to the early days of computing when tapes were used for memory. See <http://dictionary.sensagent.com/cracovian/en-en/>

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect...
