This "supercluster" of galaxies lets us peek into the universe's past
- At the same time, and on much bigger scales, these bigger galaxies were pulled closer to one another through the force of gravity, assembling into clusters and then superclusters.
- On a human scale, it's a little like looking at a daycare where you expect to see only toddlers and seeing a 2-year-old who is already the size of an adult.
- If we were able to see it as it exists now, it would presumably look more like more modern superclusters, located closer to Earth.
- It's perhaps easiest to think of the galaxies distributed across the universe as looking a little like the foam on a freshly pulled pint of Guinness stout.
- So now we have a little insight into the moment in the history of the universe when these filaments and voids began to form -- when large-scale structures began to come into existence.
Vue-emit: an npm package to dispatch events in Vue.js
- If you don't pass a listener from the parent component, there is no handler for the event (input event in our case) in context.listeners object.
- It this structure context.listeners.input in the C component will be an array of two functions: [doSomethingA, doSomethingB].
- So when using context.listeners (either directly calling handlers from this.$listeners) you have to always check that listener exists and what type it has: Function or Array.
- The first argument is an object of listeners with eventName => handler structure.
- Vue-emit will check listeners object and do nothing if handler is not defined or will call each handler if there are more than one listener.
- By the way, this is the use case with stateful components - when for some reason, you want to pass more than one argument to handler function as a payload.
Generalized Graph Networks ups Deep Learning to next level AI
- They argue for making combinatorial generalization a top priority for AI, and advocate for embracing integrative approaches which draw on ideas from human cognition, traditional computer science, standard engineering practice, and modern deep learning.
- They explored flexible learning-based approaches which implement strong relational inductive biases to capitalize on explicitly structured representations and computations, and presented a framework called graph networks, which generalize and extend various recent approaches for neural networks applied to graphs.
- These directions each involve rich notions of entities, relations, and combinatorial generalization, and can potentially benefit, and benefit from, greater interaction with approaches for learning relational reasoning over explicitly structured representations.
- We present a new building block for the AI toolkit with a strong relational inductive bias–the graph network–which generalizes and extends various approaches for neural networks that operate on graphs, and provides a straightforward interface for manipulating structured knowledge and producing structured behaviors.
A walk through Israel's poorest village made it very clear that one of the country's biggest issues is one no one talks about
- On a sunny Thursday morning, I drove with the Israeli human-rights activist Jafar Farah to the coastal Arab village, considered by many to be the poorest town in Israel.
- Shortly after, the government approved a $4.3 billion five-year plan, Resolution 922, to improve education, housing, and policing in Arab communities.
- Residents weary of violence applauded the development, but there was frustration, Farah said, that the city council had asked unsuccessfully for years for a permanent structure.
- At the government's direction, the police station was built on land that the town council had hoped to use for development.
- That day, Farah and the town council were due to show Emanuele Giaufret, the EU's ambassador to Israel, the progress made by an EU-funded, Mossawa-coordinated project to empower the town to "maximize the economic potential." One of the main plans, in the works for years, is to turn the village into a tourist destination.
A Modernism for India: Sitting with Pritzker Prize winner B.V. Doshi
- Realigning contemporary design and architecture to the needs of India has been a major theme in the life’s work of B.V. Doshi.
- Doshi’s first employment was at Le Corbusier’s atelier in Paris, where he worked on that architect’s planned city of Chandigarh, India.
- Several of Chandigarh’s most notable and impressive structures were designed by Le Corbusier himself, and while they employed some methods less than ideal for Indian building circumstances he did make considerable efforts to adapt them to the locale.
- In addition to Chandigarh, Doshi assisted Le Corbusier in the early 1950s on buildings in another Indian city, Ahmedabad.
- Doshi himself has built his largest concentration of structures in Ahmedabad, including his office building, Sangath (Sanskrit for “moving together”), which was constructed between 1978 and 1980.
Tesla Has Finally Released Its Long-Promised $35,000 Model 3. Sort Of
- Tesla’s Model 3 was originally supposed to be the company’s mass-market offering, with prices starting at $35,000 before incentives.
- The version on sale for the last year—the long-range version—costs between $49,000 and $78,000.
- On Thursday, CEO Elon Musk took to Twitter to announce a new, mid-range version of the car that costs $35,000—after federal and state tax rebates.
- In other words, the new version costs $45,000 before incentives.
- So when’s the actually-$35,000-before-incentives version of the Model 3 coming?
- While the long-range Tesla battery pack takes the car 310 miles on a charge, the mid-range version has a range of 260 miles.
- Tesla has also changed the Model 3’s option structure, making the rear-wheel drive option available only for the mid-range version of the car, although Musk said it would also be available as an “off-menu” option for long-range Model 3s over the next week.
Your brain is like 100 billion mini-computers all working together
- Each of our brain cells could work like a mini-computer, according to the first recording of electrical activity in human cells at a super-fine level of detail.
- While people have recorded signals from inside human neurons before, it has always been inside the main “trunk” of their tree-like structure.
- Compared with mice, the dendrites of human neurons turn out to have fewer ion channels, molecules studded in the cell’s outer membrane that let electricity flow along the dendrite.
- Imagine a mouse neuron: if a signal starts down one dendrite, there are so many ion channels to conduct electricity that the signal will probably continue into the main trunk of the neuron.
- In a human neuron, by contrast, it’s less certain that the signal will conduct into the main trunk: whether it does will probably depend on activity in other dendrites, says Harnett.
Some notable Facebook shareholders file (mostly symbolic) proposal to oust Mark Zuckerberg as chairman
- The pension funds of New York City are joining activist shareholder Trillium Asset Management, which has wanted to remove Zuckerberg as Facebook’s chairman since its disappointing second-quarter earnings report in July, as well as the state treasurers of Rhode Island, Illinois, and Pennsylvania.
- In an online statement, New York City comptroller Scott Stringer called on Facebook’s board to make its chair an independent position.
- The shareholder proposal was filed by the New York City Pension Funds, Illinois state treasurer Michael Frerichs, Rhode Island state treasurer Seth Magaziner, Pennsylvania treasurer Joe Torsella, and Trillium Asset Management.
- In March, he asked Facebook’s lead independent director, Dr. Susan Desmond-Hellmann, to improve the company’s data privacy accountability after the Cambridge Analytica scandal, citing the 4.9 million Class A shares held by the city’s pension funds.
