The Death Of Expertise I am (or at least think I am) an expert. Not on everything, but in a particular area of human knowledge, specifically social science and public policy. When I say something on those subjects, I expect that my opinion holds more weight than that of most other people. I never thought those were particularly controversial statements. As it turns out, they’re plenty controversial.

Nervous system The nervous system is the part of an animal's body that coordinates its voluntary and involuntary actions and transmits signals between different parts of its body. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago. In most animal species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). Auntie Dogma's Garden Spot Perennial, Viola Tricolor Johnny Jump Ups are a popular viola. They are called “old fashioned” favorites. These perennials are often grown as an annual, especially in northern parts of the country. Johnny Jump Ups are native to Spain and the Pyrennes Mountains.

Spinal cord The spinal cord is a long, thin, tubular structure made up of nervous tissue, that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord that contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone where it passes through the foramen magnum, and meets and enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae where it ends.

The Dementia Care Economy Essay John Thackara Above: the demential care ecology of Newcastle, in North East England. Illustration by Barbara Douglas The G8 Dementia Summit made much of the fact that millions will now be spent in a race to identify a cure or a ‘disease-modifying therapy’ for dementia. In response to that grand promise, I argued that the appropriate way for nation states to spend money on dementia would be in the ratio: 95 per cent for Care, five percent for Big Research. Kevinism Kevinism and Chantalism (German: Kevinismus, Chantalismus) is used to describe the discrimination faced by children with what appears to them to be unusual, exotic-sounding first names in Germany.[1] Overview[edit] According to a master's thesis authored at the University of Oldenburg in 2009, certain given names of students can indeed lead to prejudices on the part of teachers.[4] For example, the name Kevin (of Irish origin), given to a German child, indicates to German teachers that such a student is prone to behaviour consistent with an intention to gain more attention, as well as lower scholastic performance, and is also indicative of a lower socioeconomic status.

Dura mater Dura mater, or dura, is a thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord. It is the outermost of the three layers of membrane called the meninges that protect the central nervous system. The other two meningeal layers are the arachnoid mater and the pia mater. The dura surrounds the brain and the spinal cord and is responsible for keeping in the cerebrospinal fluid. 20-Year-Old Hunter S. Thompson’s Superb Advice on How to Find Your Purpose and Live a Meaningful Life As a hopeless lover of both letters and famous advice, I was delighted to discover a letter 20-year-old Hunter S. Thompson — gonzo journalism godfather, pundit of media politics, dark philosopher — penned to his friend Hume Logan in 1958. Found in Letters of Note: Correspondence Deserving of a Wider Audience (public library | IndieBound) — the aptly titled, superb collection based on Shaun Usher’s indispensable website of the same name — the letter is an exquisite addition to luminaries’ reflections on the meaning of life, speaking to what it really means to find your purpose. Cautious that “all advice can only be a product of the man who gives it” — a caveat other literary legends have stressed with varying degrees of irreverence — Thompson begins with a necessary disclaimer about the very notion of advice-giving: To give advice to a man who asks what to do with his life implies something very close to egomania.

Pia mater Pia mater (/ˈpaɪ.ə ˈmeɪtər/ or /ˈpiːə ˈmɑːtər/[1]), often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning "tender mother".[1] The other two meningeal membranes are the dura mater and the arachnoid mater. Both the pia and arachnoid mater are derivatives of the neural crest while the dura is derived from embryonic mesoderm. Pia mater is a thin fibrous tissue that is impermeable to fluid. This allows the pia mater to enclose cerebrospinal fluid. By containing this fluid the pia mater works with the other meningeal layers to protect and cushion the brain.

iMac: Everything We Know The major addition to the 21.5-inch iMac line is the high-end model that now includes a 4K Retina display to complement the 5K Retina iMac that's been around since 2014. Apple is selling the 4K iMac alongside two lower-priced non-Retina models, and all three models have been updated with faster Broadwell processors and integrated Intel graphics. There are no longer discrete graphics options for the 21.5-inch iMac models, even at the high end, and all models ship with a 1TB hard drive as a base option and 8GB RAM. Design wise, the 21.5-inch iMac continues to look like the previous-generation iMac, with an ultra thin 5mm thick laminated display.

Phantom time hypothesis Conspiracy theory The phantom time hypothesis is a historical conspiracy theory asserted by Heribert Illig. First published in 1991, it hypothesizes a conspiracy by the Holy Roman Emperor Otto III, Pope Sylvester II, and possibly the Byzantine Emperor Constantine VII, to fabricate the Anno Domini dating system retrospectively, in order to place them at the special year of AD 1000, and to rewrite history[1] to legitimize Otto's claim to the Holy Roman Empire. Illig believed that this was achieved through the alteration, misrepresentation and forgery of documentary and physical evidence.[2] According to this scenario, the entire Carolingian period, including the figure of Charlemagne, is a fabrication, with a "phantom time" of 297 years (AD 614–911) added to the Early Middle Ages.

Membrane Schematic of size based membrane exclusion A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Biological membranes include cell membranes (outer coverings of cells or organelles that allow passage of certain constituents);[1] nuclear membranes, which cover a cell nucleus; and tissue membranes, such as mucosae and serosae. Synthetic membranes are made by humans for use in laboratories and industry (such as chemical plants). This concept of a membrane has been known since the eighteenth century, but was used little outside of the laboratory until the end of World War II.

Building a text database using Tinderbox – The Eclectic Light Company I’ve been writing Question and Answer (Q&A) sections for Mac publications for longer than I care to remember. Despite having advised many questioners to use tools like Tinderbox to help them structure their work and keep it in order, I’ve never been particularly good at that myself. Currently, I write the Genius Tips section for MacFormat, which with its sister title Mac|Life are, I believe, the last general-readership Mac magazines still in print.

Nerve A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs. In the central nervous system, the analogous structures are known as tracts.[1][2] Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
