Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning.
Knowledge can refer to a theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); it can be more or less formal or systematic. In philosophy, the study of knowledge is called epistemology; the philosopher Plato famously defined knowledge as "justified true belief", though "well-justified true belief" is more complete as it accounts for the Gettier problems. However, several definitions of knowledge and theories to explain it exist.
Knowledge acquisition involves complex cognitive processes: perception, communication, and reasoning; while knowledge is also said to be related to the capacity of acknowledgment in human beings.
Quartz is the second-most-abundant mineral in Earth's continental crust, after feldspar. Its crystal structure is a continuous framework of SiO4silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Europe and the Middle East.
The word "quartz" is derived from the German word "Quarz" and its Middle High German ancestor "twarc", which probably originated in Slavic, cf. Czech tvrdý ("hard"), Polish twardy ("hard"), Serbian and Croatian tvrd ("hard").
The Ancient Greeks referred to quartz as κρύσταλλος (krustallos) derived from the Ancient Greek κρύος (kruos) meaning "icy cold", because some philosophers (including Theophrastus) apparently believed the mineral to be a form of supercooled ice. Today, the term rock crystal is sometimes used as an alternative name for the purest form of quartz.
Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.
Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.
The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

Workers at Hitachi have found a way to save data on quartz crystal giving way to a theory that the crystal skulls may not acually be so barren after all. Scientists have been working with flag planes of quartz glass and hope that development will shed light on the possibility of how to read the crystal skulls even though no current technology has shown any indication that data is on them.
5D data: small disc of quartz for storing up to 360 TB for millions of years. For years we have evolved the way we store our information, from cassette tape via diskettes, CDs, DVDs, Blu-Rays, until mechanical hard disks and now SSDs, which continue to grow impressively, reaching a capacity for years sounded simply impossible. But now thanks to a group of researchers from the University of Southampton, know a new and interesting form of storage, consisting of five-dimensional nanostructures within a quartz crystal, thus bringing the possibility of having almost eternal form, an amount brutal information securely in a small disk. Storage (almost) eternal in 5D The recording technique is based on small laser pulses of very short duration, we are talking femtosecond, which generate a three-l...
A new method for single cell transcriptome measurement is developed. I'm impressed by the progress in data quality, but still it's really challenging. I hope you take a look the data by yourself. Please download the ssa file to view the data on your computer. Subio Platform is freely available and you don't need plug-ins for viewing data. For example, because FPKM is normalized signals and the meaning of FPKM value depends on data quality or RNA abundance. This could be "arguable" and I believe non-informaticians are requested to join the discussion. For more information. https://www.subioplatform.com/info_casestudy/8/

Algorithms can be wizardly at making connections between seemingly disparate people and things, finding similarities and undercurrents where there seems to be nothing. They can be serendipity machines, showing us the information we don’t even know that we need or want, just when we need or want it. But is this any replacement for “real” serendipity – true random luck or kismet? Is it any less authentic or magical? On the other hand, how do we deal with the knowledge that these serendipity algorithms can be gamed: someone might be paying to make serendipity happen at specific times and places (“the algorithmic ruse”).

Slides: https://slidr.io/Chimney42/machine-learning-with-synaptic In this talk, I'll be telling you about: * how neural networks do their magic * how I implemented a simple neural network * how to check the performance of the algorithm * how to tackle the error rate
“Lesson 0” was a deep learning lesson that we snuck into the launch of the Data Institute at USF. No-one in the audience knew they were about to learn about convolutional neural networks! The talk is in two parts: * The first half is a high level overview of deep learning * The second half is a very rapid introduction to the convolution operation and stochastic gradient descent. This lesson is much lower audio and video quality than the other lessons—the other lessons were recorded directly from the screen and used a professional microphone. Furthermore, most of the material in this talk is covered more thoroughly in other lessons. Nonetheless, you may find it helpful to watch this video after watching lesson 1 and 2.

The practice of Takahiro Ueda is interdisciplinary, recalling a scientific researcher observing natural phenomena: atoms, chemical elements, sound vibrations, weather and environmental changes. His work is realised in collaboration with teams of experts including quartz miners, scientists and engineers. Ueda combines technological experimentation and fine art – the audio-visual performance Track of At[o]m uses apparatus which receives a satellite radio wave for only 15 minutes when a satellite is overhead. The signal is interpreted as both information display and sound, adjusted according to interference with the signal by other human activities, and modulated by the artist. Another example of his practice is Invisible Movement, utilising naturally occurring phenomena to explore ideas re...
Presented by Johann Swanepoel at the ASSA Symposium, 2012 October 13, at SAAO in Cape Town. "The purpose of the presentation will be to share my experiences and knowledge gained in the making of two 20-inch f/4.3 telescope mirrors. It will cover details of a versatile machine that was built for the grinding, polishing and figuring of the mirrors. It will further include details of the various full and sub-diameter tools that were made and used. An explanation will be presented on the optical testing methods used throughout the figuring process, including an improved application of the Foucault test and the corresponding digital data reduction techniques."

Secrets of the 13 Crystal Skulls - 2017 Documentary
What is the secret link between rocks and minerals, and every living thing on Earth? Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged.
