The LSST Camera is the largest digital camera ever built for astronomy and astrophysics. It was completed at SLAC National Accelerator Laboratory in 2024.
The word “manuscript” from the Latin words manus (hand) and scriptus (writing) literally means “written by hand.” Before the invention of printing, copies of books had to be handwritten. A scribe would obtain a book to copy and painstakingly write out every word, in ink with a quill pen.
The Patrologia Latina covers the works of the Latin Fathers from Tertullian around 200 AD to the death of Pope Innocent III in 1216. In 221 volumes, it covers most major and minor Latin authors, and contains the most influential works of late ancient and early medieval theology, philosophy, history, and literature.
A destination for discovery, shared exploration, and sheer joy, Oculi Mundi is the online home of The Sunderland Collection of antique maps and atlases.
Greenough advocated an empirical approach to the early science; his scepticism of theoretical thinking courted controversy amongst some contemporaries, especially his doubts of the usefulness of fossils in correlating strata. He compiled a geological map of England and Wales, published in 1820
Hidden data hinders book evaluation. Analysing ISBNs in the Global Register of Publishers gains a powerful tool for bibliometrics, policy development, and nuanced book metrics.
This quote from Charity Majors is probably the best summary of the current state of observability in the tech industry - a total, mass confusion. Everyone is confused. What is a trace? What is a span? Is log line a span? Do I need traces if I have logs? Why I need traces if I have great metrics?
LEME searches and displays word-entries from monolingual English dictionaries, bilingual lexicons, technical vocabularies, and other encyclopedic-lexical works, 1480-1755.
Everywhere in education, you see incentives at work. The incentives, though, are so far removed from the actual goals of education that they produce perverse results.
Goodhart’s Law is usually stated, “When a measure becomes a target, it ceases to be a good measure.”
As a schoolchild, she had delighted in using a pendulum to make drawings in her exercise books, but it was not until midlife that she found in this process a portal to a larger world of ideas. In 1938, using a silver pendulum with a jade end she believed was guided by energy fields — a technique she termed radiesthesia — she began making large-scale drawings in pencil and crayon on graph paper, hundreds of them, to divine diagnoses of physical and psychic ailments and heal people, often with results bordering on the miraculous.
Every now and then I want to generate normally distributed values in something like Perl, which does not have built-in functions for it. Unfortunately, there’s no easily remembered way to generate numbers from the normal distribution. I just learned the best way to do it: don’t. Generate logistically distributed values instead.
The Manners and Customs of the Middle Ages:--this subject is of the greatest interest, not only to the man of science, but to the man of the world also. In it, too, "we retrace not only one single period, but two periods quite distinct one from the other."
The Atlas of Early Printing is an interactive site designed to be used as a tool for teaching the early history of printing in Europe during the second half of the fifteenth century. While printing in Asia pre-dates European activity by several hundred years, the rapid expansion of the trade following the discovery of printing in Mainz, Germany around the middle of the fifteenth century is a topic of great importance to the global history of communications, technology, and the dissemination of knowledge.
