For some reason Chinese people (and their sphere of influence such as Japan) are obsessed by numbered lists, e.g. stuff like Four Beauties, Four Treasures of the Study and so on!
The concept does exist in the West (e.g. The Seven Wonders of the World), but clearly the Sinosphere is much more obsesse by it!

Source. Given enough computational power per dollar, AGI is inevitable, but it is not sure certain ever happen given the end of end of Moore's Law.
Alternatively, it could also be achieved genetically modified biological brains + brain in a vat.
Imagine a brain the size of a building, perfectly engineered to solve certain engineering problems, and giving hints to human operators + taking feedback from cameras and audio attached to the operators.
This likely implies transhumanism, and mind uploading.
Ciro Santilli joined the silicon industry at one point to help increase our computational capacity and reach AGI.
Ciro believes that the easiest route to full AI, if any, could involve Ciro's 2D reinforcement learning games.

\x[image-the-python-logo]Now, when rendering
\x[image-the-python-logo], we would need to fetch two IDs:image-the-python-logofor theTheandlogopartpython-programming-languageitself, to know that\x[python-programming-language]should render asPython
But after group all SQL queries together was done, there was no way to know that rendering
image-the-python-logo would imply also fetching python-programming-language.This was solved by adding a new database entry type,
REFS_TABLE_X_TITLE_TITLE to the existing References table, which tracks dependencies between IDs.After this was setup, we can now know that
image-the-python-logo depends on image-the-python-logo, and then fetch both of them together in a single JOIN.Suppose that a rod has is length measured on a rest frame (or maybe even better: two identical rulers were manufactured, and one is taken on a spaceship, a bit like the twin paradox).
Question: what is the length than an observer in frame moving relative to as speed observe the rod to be?
The key idea is that there are two events to consider in each frame, which we call 1 and 2:Note that what you visually observe on a photograph is a different measurement to the more precise/easy to calculate two event measurement. On a photograph, it seems you might not even see the contraction in some cases as mentioned at en.wikipedia.org/wiki/Terrell_rotation
- the left end of the rod is an observation event at a given position at a given time: and for or and for
- the right end of the rod is an observation event at a given position at a given time : and for or and for
Measuring a length means to measure the difference for a single point in time in your frame ().
So what we want to obtain is for any given time .
In summary, we have:
By plugging those values into the Lorentz transformation, we can eliminate , and conclude that for any , the length contraction relation holds:
The key question that needs intuitive clarification then is: but how can this be symmetric? How can both observers see each other's rulers shrink?
And the key answer is: because to the second observer, the measurements made by the first observer are not simultaneous. Notably, the two measurement events are obviously spacelike-separated events by looking at the light cone, and therefore can be measured even in different orders by different observers.
In this solution of the Schrödinger equation, by the uncertainty principle, position is completely unknown (the particle could be anywhere in space), and momentum (and therefore, energy) is perfectly known.
The plane wave function appears for example in the solution of the Schrödinger equation for a free one dimensional particle. This makes sense, because when solving with the time-independent Schrödinger equation, we do separation of variable on fixed energy levels explicitly, and the plane wave solutions are exactly fixed energy level ones.
Some less-trivial breakthroughs:
- finding 2013 DNS Census
- CGI comms characterization
- secure subdomain search on 2013 DNS Census let to a few hits
- 2013 DNS Census virtual host cleanup heuristic keyword searches was massive and led to many new ranges
Previously it was unclear if there were any .org hits, until we found the first one with clear comms: web.archive.org/web/20110624203548/http://awfaoi.org/hand.jar
Later on, two more clear ones were found with expired domain trackers:further settling their existence. Later on newimages.org also came to light.
- azerinews.org
- autism-news.org
Others that had been previously found in IP ranges but without clear comms:
- 65.61.127.177: material-science.org
- 212.4.17.61: tech-stop.org
Others in IP ranges by unarchived:
- 74.116.72.244 arborstribune.org
.org is very rare, and has been excluded from some of our search heuristics. That was a shame, but likely not much was missed.
AMO is a slightly more general area than condensed matter physics, including related phenomena with smaller numbers atoms and optics. The two terms are however sometimes used as synonyms. The term AMO has gained wide usage and acceptability, see e.g.:
If Ciro had had greater foresight, this might have been what he studied at university!
