The Sharpest Object In The World Can’t Cut Anything

Head to https://linode.com/scishow to get a $100 60-day credit on a new Linode account. Linode offers simple, affordable, and accessible Linux cloud solutions and services.

Scientists like to measure things, but they’ve had a heck of a time doing that with sharpness. And even if no one agrees on exactly how to measure it, our search for better tools has recently led to some of the sharpest objects we’ve ever created.

New MIT/Caltech Ingestible Sensor Could Help Doctors Pinpoint GI Difficulties

The sensor sends out its location as it moves through the GI tract, revealing where slowdowns in digestion may occur.

Engineers at MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.

The World in 2100 — Truly MIND BENDING Technologies Will Exist by the Turn of the Century

Are you ready to discover the potential technological developments that could shape the world we live in and get a glimpse of what life in the year 2100 might be like? As we approach the turn of the century, the world is expected to undergo significant changes and challenges. In this video, we will show you how the merging of humans and artificial intelligence can help solve any problem that comes our way and even predict the future.

Imagine being able to access the thoughts, memories, and emotions of billions of people through the hive mind concept. This will provide a unique way of experiencing other people’s lives and gaining new perspectives. Hyper-personalized virtual realities customized to fulfill every individual’s desire will be the norm. Users will enter a world where their every wish and fantasy constantly comes to life, maximizing their happiness, joy, and pleasure.

Education as we know it will change forever with the ability to download skills and knowledge directly into a person’s brain. People will be able to learn new skills and gain knowledge at unprecedented speeds, becoming experts in any field within seconds. The discovery and use of room-temperature superconductors will revolutionize many industries and transform the world’s infrastructure, especially in transportation. By 2100, this technology will be a reality and used in numerous industries.

When will a computer surpass the human brain?

This is a clip from Technocalyps, a documentary in three parts about the exponential growth of technology and trans-humanism, made by Hans Moravec. The documentary came out in 1998, and then a new version was made in 2006. This is how the film-makers themselves describe what the movie is about:

“The accelerating advances in genetics, brain research, artificial intelligence, bionics and nanotechnology seem to converge to one goal: to overcome human limits and create higher forms of intelligent life and to create transhuman life.”

You can see the whole documentary here: https://www.youtube.com/watch?v=fKvyXBPXSbk. Or, if you’re more righteous then I am, you can order the DVD on technocalyps.com.

“Musk,” a new documentary, is being shot by an acclaimed filmmaker

“Now is the moment for a rigorous portrait of Elon Musk.”

Alex Gibney, an award-winning filmmaker, is working on a new documentary about Elon Musk. The movie “Musk” aims to be “a definitive and unvarnished investigation” of the multibillionaire CEO of SpaceX, Tesla, and Twitter. The project has been in the works for months.

Other documentaries by Gibney have explored topics such as Steve Jobs, Enron, WikiLeaks, Elizabeth Holmes, Scientology, and more.

“I have been working on this film, off and on, for some time and am hugely excited about it,” said Gibney, as reported by Business Insider. “I am delighted by this extraordinary group who are working with me. Onward!”

Why lifelong learning is the international passport to success

What is it with this thin sheet of paper that makes it so precious? It’s not only the proof of acquired knowledge but plays into the reputation game of where you were trained. Being a graduate from Harvard Law School carries that extra glitz, doesn’t it? Yet take a closer look, and the diploma is the perfect ending to the modern tragedy of education.

Why? Because universities and curricula are designed along the three unities of French classical tragedy: time, action, and place. Students meet at the university campus (unity of place) for classes (unity of action) during their 20s (unity of time). This classical model has traditionally produced prestigious universities, but it is now challenged by the digitalisation of society – which allows everybody who is connected to the internet to access learning – and by the need to acquire skills in step with a fast-changing world. Universities must realise that learning in your 20s won’t be enough. If technological diffusion and implementation develop faster, workers will have to constantly refresh their skills.

The university model needs to evolve. It must equip students with the right skills and knowledge to compete in a world ‘where value will be derived largely from human interaction and the ability to invent and interpret things that machines cannot’, as the English futurist Richard Watson puts it. By teaching foundational knowledge and up-to-date skills, universities will provide students with the future-proof skills of lifelong learning, not just get them ‘job-ready’.

Scientists Have Finally Discovered Massless Particles, And They Could Revolutionize Electronics

After 85 years of searching, researchers have confirmed the existence of a massless particle called the Weyl fermion for the first time ever. With the unique ability to behave as both matter and anti-matter inside a crystal, this strange particle can create electrons that have no mass.

The discovery is huge, not just because we finally have proof that these elusive particles exist, but because it paves the way for far more efficient electronics, and new types of quantum computing. “Weyl fermions could be used to solve the traffic jams that you get with electrons in electronics — they can move in a much more efficient, ordered way than electrons,” lead researcher and physicist M. Zahid Hasan from Princeton University in the US told Anthony Cuthbertson over at IBTimes. “They could lead to a new type of electronics we call ‘Weyltronics’.”

So what exactly is a Weyl fermion? Although we’re often taught in high school science that the Universe is made up of atoms, from a particle physics point of view, everything is actually made up of fermions and bosons. Put very simply, fermions are the building blocks that make up all matter, such as electrons, and bosons are the things that carry force, such as photons.
