According to the museum, the sword is about 33 inches long and “exceptionally well-preserved.” It even has a sheath made of wood and leather.

Further searching in the lake yielded a piece of metal jewelry from A.D. 300-400.

When yellow pinion rotates clockwise, blue rack gets its left end position, stay there till the pinion changes its rotary direction and vice versa. Pink movable teeth maintain rack – pinion engagement when the rotary direction is changed. Two brown stoppers in accordance with the rack length set the rack end positions.

The world's largest wind turbine blade manufactured by GE. It measures 107m long. It is one of the longest machine components ever manufactured and is the first to be built at the new LM Wind Power Factory in France. Three of these blades will form GE's Haliada-X 12MW offshore wind turbine. This is the most powerful wind turbine in the world and will be capable of powering 16000 homes. It is due to begin operation later this year. The brand-new factory where LM Wind Power makes the massive blades for the Haliade-X 12MW is located on the banks of the English Channel in Normandy, just a short drive from the wide, sandy beaches where Allied troops landed on D-Day. LM Wind Power built the plant near Cherbourg’s industrial port to allow workers to load the blades onto ships and send them to their destination. Operating in three shifts, workers build the blades from a high-tech sandwich made from thin layers of glass and carbon fibers, and wood. They fuse everything together with a special resin. GE Renewable Energy will put two blades through rigorous testing to demonstrate their ability to withstand more than 20 years of spinning offshore. 🌬🌊🔧⚙ #renewableenergy #energy #windturbine #turbineblade #manufacturing #offshorewindturbine #ge #generalelectic #electrical #electricalengineering #electronic #electronicengineering #lmwindpower #carbonfibre #fibreglass #engineering_memes #engineeringlovers #engineeringlife #engineeringblog #engineeringfirstprinciples #engineer #engineering #engineeringbasics #engineeringmemes #engineeringstudents #technology #innovation

Shrink-fitting is a technique in which an interference fit is achieved by a relative size change after assembly. This is usually achieved by heating or cooling one component before assembly and allowing it to return to the ambient temperature after assembly, employing the phenomenon of thermal expansion to make a joint. #worldofengineering #metalwork #nitrogen #metalworking #australia #tasmania Video by @glasgowengineering

Researchers at the University of Stuttgart have devised a new method of construction using mini robots that they claim is cheap, fast and can create structures that would otherwise be impossible to build. Instead of using one or two large robots, their carbon fibre fabrication method involves many small robots that look like Roomba vacuums and could fit inside a single suitcase. The agile robots, which climb walls and ceilings, work in concert to pull fibre filaments across a space, creating a structure on-site. ─────┈┈┈┄┄╌╌╌╌┄┄┈┈┈───── ᖴOᒪᒪOᗯ @_brain_ideas_🗺TᗩG YOᑌᖇ ᖴᖇIEᑎᗪS👫⠀ ╭──────────────────────╮ ▪▪▪▪DM for promo / business inquiries▪▪▪▪ ╰──────────────────────╯ #_brain_ideas_#slovakia#Eesti#paris#lisboa#Italia #España#france#Slovenija#madrid#Malta#Greece #Schweiz#Ireland#Belgique#Nederland#Österreich #germany#Portugal#Luxembourg#Finland#Cyprus #london#SaintHelena#berlin#Suisse#roma#Latvia #England#Scotland ─────┈┈┈┄┄╌╌╌╌┄┄┈┈┈─────

Curie Point Heat Engine: when the magnet on the end of the wire heats up to a particular temperature (the Curie point) its magnetic field is temporarily lost until it cools. This engine design uses a second magnet to pull the swinging magnet back into the heat source once the magnetic field is reestablished. Repetition of this process creates mechanical motion as long as the heat source is fueled. ➡️ Follow the link in my profile for info on where to get many of the amazing devices featured here on @physicsfun #PierreCurie #curiepoint #magnetism #magnets #magneticfield #heat #heatengine #physics #physicstoy #candle #neodymium #science #scienceisawesome

Iberian peninsula 4500 years ago

The invasion that wiped out every man from Spain 4,500 years ago

New research indicates all local males on the Iberian peninsula were killed by hostile invaders with superior technology

MANUEL ANSEDE 4 OCT 2018 – 02:36 EDT

https://elpais.com/elpais/2018/10/03/inenglish/1538568010_930565.html

More than 5,000 years ago a nomadic group of shepherds rode out of the steppes of eastern Europe to conquer the rest of the continent. The group, today known as the Yamna or Pit Grave culture, brought with them an innovative new technology, wheeled carts, which enabled them to quickly occupy new lands. More than 4,500 years ago, the descendants of these people reached the Iberian peninsula and wiped out the local men, according to new research by a team of international scientists.

colonized by the first Neolithic migration wave 8,000 or 9,000 years ago but also by a later one 4,500 years ago, which brought with it a very different culture

War axes and carts with four wheels can be found in the layers of earth that date back 4,500 years. “From then on, almost all men’s tombs were filled with weaponry, adornments, displays of wealth. The archaeology reveals marked signs of a hierarchical society that broke with the old egalitarianism of the early Neolithic period.

This research team announced they had discovered a “discontinuity” in the Y chromosome during the Bronze Age in the Iberian Peninsula, after studying the DNA of the remains of 14 people found in archaeological sites in Portugal.

“In terms of why the Y chromosome was replaced, we could speculate that the populations from the steppes had superior technology, better weapons and also domesticated horses that could have given them an advantage in war

men in humanities

We Need More Men in the Humanities

Around the turn of the millennium, American society realized a looming crisis: the lack of female representation in STEM fields. But today we are witnessing a crisis of male leadership in a variety of workplaces. From the president to CEOs of major companies to actors and power players in Hollywood, the past several months have exposed the toxic work environments they preside over or worsen in scandal after scandal. Though different in nature, this crisis is of equal importance as the STEM shortage. Yet, to date, no prominent solutions or interventions have been seriously proposed. In contrast, a quick Google search brings up dozens of programs for girls in STEM, but not one national program appears for boys in the arts and humanities.
latest indicators of the demographics and earnings of public school humanities teachers — most of whom are women and many of whom aren’t paid well — underscore that we need more men in the arts and humanities.
 The Humanities Indicators report that, “As of 2015, women earned 61 percent of all master’s and professional-practice degrees in the humanities and 54 percent of the doctoral degrees in the field.” And the latest report on public school teachers found that “76 percent of humanities teachers were women, the largest share among subject specialists.” When male K-12 role models barely exist in these disciplines, what message does that send to our young boys and men?
You may have heard of Girls Who Code, the National Girls Collaborative Project, the National Math and Science Initiative, the Women in Engineering Proactive Network or the Million Women Mentors. Those programs are increasing the number of STEM graduates over all and injecting some much-needed diversity into the fields.
But our society suffers when boys and men are actively discouraged from pursuing their interests in the arts and humanities. The cycle of toxic masculinity starts early. Boys are often told not to cry or show emotion. They are socially trained to repress it, and they take pride in this false resilience.
the Rhode Island School of Design Museum. In an annual event called “Cops and Docs,” accomplished medical professionals and highly trained police officers take a group trip to the museum. Over the course of the evening, mixed groups of cops and docs look at paintings, sculptures and other works of art, and they then share their answers to a pretty basic question: What do you see?
Another program, “The Art of Perception,” takes police detectives, FBI agents and high-ranking Secret Service and CIA executives to well-known museums and galleries like the Metropolitan Museum of Art and the Frick Collection to observe works by Picasso, Caravaggio, Edward Hopper and other masters. Program creator Amy E. Herman says the exercise is “not about looking at art. It’s about talking about what you see.

first VR optometry lab

University of Waterloo to have first virtual reality optometry lab in Canada

FRIDAY, SEPTEMBER 28, 2018 https://uwaterloo.ca/news/news/university-waterloo-have-first-virtual-reality-optometry-lab

A new virtual reality (VR) training lab at the University of Waterloo’s School of  Optometry and Vision Science, will help Canada’s next generation of optometrists learn how to diagnose vision problems and eye diseases more quickly and accurately.

The new lab, funded through an $800,000 investment by national eye care provider FYidoctors, At a total cost of $1.5 million, the FYidoctors Simulation Lab is the first of its kind in Canada and will ensure the School remains at the forefront in optometric education in North America.

Dr. Al Ulsifer, CEO and Chairman of FYidoctors and  Waterloo alumnus, said that this investment isn’t just an investment in the University, but a stake in the future generation of optometrists.

The Equipment:

The lab will initially include 5 Eyesi® Binocular Indirect Ophthalmoscopes (BIO) are state of the art augmented reality simulator for training of retinal examinations and provides a highly realistic and dynamic 3D simulation of the anatomical structures of the eye and ophthalmoscope optics.

For more detailed information visit:  https://www.vrmagic.com/simulators/feature-pages/indirect/

Phase two of the lab, to be unveiled at a later date, will include the addition of the Eyesi® Slit Lamp simulators.  This technology will allow students to practice basic handling of the device and skills required to conduct a corneal exam, retinal exam and Gonioscopy & Tonometry.

The monopoly of the tech giants

Here’s the real danger that Facebook, Google, and the other tech monopolies pose to our society

Jamie Bartlett, October 1, 2018, https://blog.ed.ted.com/2018/10/01/heres-the-real-danger-that-facebook-google-and-the-other-tech-monopolies-pose-to-our-society/

distributed computing + power encryption = the future of Internet

the Dark Net is going mainstream, liberty, freedom, democracy; neither entirely dark, not entirely light, both things

The threat that tech monopolies pose to democracies is about more than the prices they charge: it’s the concentration of power, data and control over the public space — and their ability to wield this power over a growing number of economic activities, especially in the infrastructure and technologies of the future. The following companies operate as either monopolies or oligopolies in their respective fields: Google, Facebook, Uber, Airbnb, Amazon, Twitter, Instagram, Spotify. Integrated into everything, everywhere, their technology will blanket the world.

cultural hegemony.” That is, where domination can be achieved through controlling the ideas and assumptions available to the public. The idea, associated with philosopher and politician Antonio Gramsci

In 1995, left-wing academics Richard Barbrook and Andy Cameron detailed the philosophy and ideas of the new tech wunderkinds, christening it “The Californian Ideology.” This ideology represented a fusion of the cultural bohemianism of San Francisco and entrepreneurial free market zeal.

All you needed to get to utopia was a belief in “disruption,” the idea that progress is achieved through smashing up old industries and institutions and replacing them with something new and digital.

Money and ideas in Silicon Valley have a very complicated relationship. Silicon Valley runs according to a Faustian pact: money in exchange for world-changing ideas.

Over the years, the big tech firms have very carefully cultivated the Californian Ideology. Even though they are massive multi-billion-dollar corporations with huge PR teams, they pitch themselves as anti-establishment.The worse these companies behave and the richer they become, the more they spend on looking cool and talking about fairness and community.

And to whom do we look in order to solve our collective social problems? It’s no longer the state, but the modern tech-geek superhero.

Total victory for the monopoly is not over economics or politics. It’s over assumptions, ideas and possible futures.
