How to be a good ancestor | Roman Krznaric

Take action on climate change at http://countdown.ted.com.

Our descendants own the future, but the decisions and actions we make now will tremendously impact generations to come, says philosopher Roman Krznaric. From a global campaign to grant legal personhood to nature to a groundbreaking lawsuit by a coalition of young activists, Krznaric shares examples of ways we can become good ancestors — or, as he calls them, “Time Rebels” — and join a movement redefining lifespans, pursuing intergenerational justice and practicing deep love for the planet.

The technology that’s replacing the green screen

The green screen is a Hollywood staple. Should it be?

It’s easy to complain about overreliance on special effects, but for projects that require impossible-to-film environments or have incredibly expensive shots, how do you get the flexibility of green screens without the drawbacks?

Charmaine Chan has worked on one of the possible answers. Vox’s Phil Edwards spoke to her about her career and how it’s at the forefront of a big technological shift. As a compositor for venerable effects house Industrial Light and Magic (ILM), she’s worked on films like The Last Jedi, assembling various digital elements into a beautiful, seamless image. Her job changed on The Mandalorian, one of the first shows to use ILM’s upgrade for the green screen: LED panels that used video game engine technology to place a realistic-looking world behind the actors.

It was a huge improvement, because green screens actually have a lot of drawbacks. Removing the green screen is never as quick as visual effects artists would hope. It also casts green light upon the set and actors. Even substitutes for a green screen, like projecting an image onto a screen behind the actor, fail to dynamically respond to camera movements the way they would in the real world.

ILM’s solution fixes a lot of those problems, and it also led to creative breakthroughs in which the old Hollywood order of a TV show or movie, in which VFX came last, was suddenly reversed. Now, artists like Charmaine are alongside actors, set designers, and other crew members during filming. That collaboration means that this technology doesn’t just eliminate a screen — it eliminates a creative barrier.

Fusion Energy Could Be a Reality in Less Than 5 Years

SPARC is aiming to be the first experimental device to achieve an energy-positive fusion reaction. New research suggests that this goal may soon be within reach.
» Subscribe to Seeker! http://bit.ly/subscribeseeker
» Watch more Elements! http://bit.ly/ElementsPlaylist
» Visit our shop at http://shop.seeker.com

With construction slated to begin in spring 2021, the team predicts it could be built within 3 to 4 years from that. Their goal is to achieve a Q factor of at least 2, basically meaning SPARC will pump out twice the energy needed to power it.

Actually, by the calculations in their papers, SPARC could possibly achieve a Q ratio of 10! But the researchers are cautious about overpromising, and are just focused on achieving the lower figure.
It’s still impressive, considering any net gain would be a first for human created controlled fusion.

Assuming it gets built along that predicted 3-4 year timeline and actually gets flipped on, there’s still several steps between SPARC and limitless clean energy.

Alice Hamilton: The Doctor Who Made Work Safer | Great Minds

During the period of rapid industrialization at the turn of the 20th century, factory jobs were incredibly unsafe. That is, until Dr. Alice Hamilton basically became an investigative reporter to figure out how factories were poisoning workers with lead! Oh, and some of her other research popularized mask-wearing as a way to reduce the spread of disease – a practice that is extremely relevant in the time of COVID-19.

The hidden treasures of Timbuktu – Elizabeth Cox

Dig into the ancient manuscripts, scrolls, and books of Timbuktu— and find out why they’ve been hidden for centuries.

On the edge of the vast Sahara desert, citizens snuck out of the city of Timbuktu and took to the wilderness. They buried chests in the desert sand, hid them in caves, and sealed them in secret rooms. Inside these chests was a treasure more valuable than gold: the city’s ancient books. Why were they hiding these priceless manuscripts? Elizabeth Cox digs into the literary tradition of Timbuktu.

Epistemological Elitism & the Power of Perspective | Grace Stearns | TEDxYouth@ASF

Ever sat in history class and felt like there was something missing from what you were learning? Grace did too. In a talk about how knowledge has consistently excluded minorities to keep a narrative of privilege, she reexamines our idea of experts as “people with lots of degrees” and shows us the wealth of perspectives that history, as we know it, has missed out on by deliberately excluding them. I have been an educator in Mexico City for the past 9 years, prior to which I was an instructor of Art, Design, Humanities, and Life skills courses at Ventura County Probation Agency where I taught incarcerated youth in Oxnard, California. I studied my Undergraduate degree at the University of Colorado at Boulder where I majored in Ethnic Studies and Studio Art. My focus in Undergrad was on Native American Contemporary History, Drawing, and Digital Media. I have a Masters Degree in Secondary Education from the University of Alabama at Tuscaloosa (International program) and also studied Drawing and Painting at Academia de San Carlos (UNAM), in Mexico City. Before working in traditional educational settings, I worked at Direct Relief (International Humanitarian Aid/Health NGO), in the food and beverage industry, and as a freelance illustrator and graphic designer. I am originally from California (Santa Barbara and Palo Alto) but have lived in Mexico City for the past 13 years.

Song created by Mitchell Moffit

LYRICS:

VERSE 1
See the chest
You can flex
Your pectoralis
Major out
Minor in
So that you can press
Underneath
On the ribs
Is the serratus
Anterior
For boxing fitness

Turn the neck
Sternocloidomastoid is here
Omohyoid
Sternohyoid
Work in tandem dear
On the back
Now the trapezius appear
Upper, Middle and Inferior

Shoulders up
Shoulders down
Feel the deltoids work
Abduction of your little arms
The biceps brachii
And brachialis
Flex the elbow, looking strong

Turn around
The triceps
Cause extension
In the shape of a horseshoe
To the forearm
Brachioradialis
Carpi ulnaris times two

Add the carpi radialis; flexor, extensor, too
The hand has many muscles, that we’re not going through

CHORUS
This is the muscle song

Why American public transit is so bad | 2020 Election

Most Americans have no choice but to drive. How do we change that?

What do you wish the presidential candidates would talk about? http://vox.com/ElectionVideos

In the middle of the 20th century, the US government made a decision that would transform American cities: It built a huge system of interstate highways, many of which went right through the downtowns of its biggest cities.

This sealed the country’s fate as a car culture, and today we’re seeing the results. In most cities, it’s extremely difficult to get around without a car, in part due to public transit systems built to serve an outdated commute. And when our politics turn to infrastructure, the government often favors building new roads and highways instead of improving and expanding public transportation.

The result is a system that forces more Americans to drive, at the expense of those who rely on public transit. It’s also the biggest contributor to our country’s carbon footprint. Fixing that over the long term will require a reimagining of American cities and towns. But there’s also a way that, if we wanted to, we could improve American transit systems, and get more people riding them, in a matter of weeks.

This video is the seventh in our series on the 2020 election. We aren’t covering the horse race; instead, we want to explain the stakes of the election through the issues that matter most to you. To do that, we want to know what you think the presidential candidates should be talking about. Tell us here: http://vox.com/ElectionVideos

The Z Machine Recreates a Dying Star on Earth

The age of the universe might be wrong, so a team of astrophysicists are using the Z Machine to recreate a piece of it on Earth. What does it take to resurrect a white dwarf star in the lab?
»Subscribe to Seeker! http://bit.ly/subscribeseeker
»Watch more Focal Point | https://bit.ly/2s0cf7w
» Visit our shop at http://shop.seeker.com

With its 36 Marx generators and more than TWO THOUSAND capacitors the Z Machine can store MORE THAN 20 MEGAJOULES of energy and fire it at a tiny target at its center.

It’s a powerful device used to uncover the mysteries of our universe.

Although the Z can’t reanimate monsters, it is helping drive innovation in the fields of radiation sciences, material sciences, and fusion studies.

Even redefining the field of astronomy by making experimentation possible.

Z Machine: Science
https://www.sandia.gov/z-machine/research/science.html
“Z provides the fastest, most accurate, and most affordable method to determine how materials will react under high pressures and temperatures, characteristics that can then be expressed in formulas called equations of state. Combining theoretical simulations with laboratory work, Sandia researchers are able to perform more precisely than ever before.”

Creating Star Stuff on Earth is the Aim of New $7 Million Project
https://cns.utexas.edu/news/creating-star-stuff-on-earth-is-the-aim-of-new-7-million-project
“To re-create the surface of a white dwarf star, UT Austin astronomer Don Winget and colleagues use the Z-machine, which converts the amount of electricity needed to power a few TV sets for the evening into a burst of energy greater than that produced by all the power plants in the world.”

White Dwarfs
https://www.nationalgeographic.com/science/space/universe/white-dwarfs/
“When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense. A teaspoonful of their matter would weigh as much on Earth as an elephant—5.5 tons.”

Making Remote Work Good Work | RSA Events

Covid-19 brought with it a mass global experiment in working from home. And with the results now in, 2020 looks set to be the year that changed office life forever.

Pandemic lockdown forced companies worldwide into a crash course in remote working. For many, it was a bumpy ride at first. But six months in, the data shows a remarkably swift and widespread adaptation to new working practices, cultures and technologies. In a recent survey, over three quarters of UK CEOs said home working is here to stay, with greater flexibility, digital transformation and lower density office space, all set to become permanent features of the future of work.

With work now increasingly what we do, rather than a place we go, leaders face new challenges to ensure remote work is good work for all. How do we maximise the gains while attending to growing concerns around employee health and wellbeing, inclusion and equity? Who wins and who loses from WFH?

Bruce Daisley is one of the world’s most influential voices on fixing work. He joins RSA US Director Alexa Clay for an essential briefing on the great remote working experiment: what we learned, and how to prepare wisely for what comes next.

Why Was the Islamic Golden Age of Science… Golden?

Around 750-1250 CE, the Islamic empire made incredible scientific advancements that still influence many fields of research today. What we know about some of the great minds of that time, as well as what we’ve learned from modern studies, suggest that the diversity of the scholars and their knowledge during that period might have played a big role in making that golden age what it was.

22 Cryptids Explained

Cryptids, or animals that have been claimed to exist without proof of their existence, span the globe. From world-famous sea beasts like the Loch Ness Monster to more obscure creatures like the Mongolian Death Worm, these stories have popped up over the years in many cultures.

Why are there so many questionable claims about the existence of apemen around the world? How do stories of cryptids spread and mutate over time? And if you’re a disobedient kid, how do you make sure you don’t get eaten by a rougarou?

Erin (@erinccmarthy) explains 22 cryptids, from the Pope Lick Monster to chupacabras.

» Visit our shop at http://shop.seeker.com

The whole point of the Z machine is to store energy, and then compress it in time and space to achieve high energy densities.

Essentially, this means the Z Machine can replicate the cosmos right here on Earth. Allowing scientists to run a wide array of experiments giving researchers the ability to study everything from plasma to x-rays to neutrons and nuclear fusion.

Expanding beyond weapons research to drive innovation in the fields of material science, renewable energy and even helping redefine our very understanding of the universe.

Find out more about the Z Machine in part 1 of this Focal Point double feature, and keep an eye out for part 2 tomorrow!

About Z
https://www.sandia.gov/z-machine/about_z/index.html
“Sandia’s Z machine is Earth’s most powerful pulsed-power facility and X-ray generator.
Z compresses energy in time and space to achieve extreme powers and intensities, found nowhere else on Earth. In approximately 200 shots Z fires every year, the machine uses currents of about 26 million amps to reach peak X-ray emissions of 350 terawatts and an X-ray output of 2.7 megajoules.”

With a touch of thermonuclear bomb fuel, ‘Z machine’ could provide fusion energy of the future
https://www.sciencemag.org/news/2016/11/touch-thermonuclear-bomb-fuel-z-machine-could-provide-fusion-energy-future
“Every time the plasma physicists at Sandia National Laboratories in Albuquerque, New Mexico, fire a shot on their fusion reactor, a big chunk of the hardware goes up in smoke. Their Z machine contains banks of capacitors that fill up with more electrical energy than a thousand lightning bolts.”

Is The Future Predetermined By Quantum Mechanics?

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity – spacetime. But if time is connected to space, could the universe be anything but deterministic? And does that mean that the future is predestined?

Can Our Parks Make Us More Resilient to Climate Change? | Katherine Peinhardt | TEDxKanzlerPark

Katherine Peinhardt’s research bridges the gap between placemaking and climate adaptation, exploring the ways that communities can build both physical and social resilience to climate change through their public spaces. Through her work at nonprofits focused on the public realm and on urban sustainability, Katherine developed a paradigm around resilient public spaces — which she sees as an often-overlooked opportunity to build livelier, more climate-adapted cities. Her research project is hosted by the German Development Institute. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

The Secret Ingredient in Ruminant Spit

Every day, humans literally flush a valuable resource down the toilet: nitrogen. But there are some animals that have figured out a way to recycle the extra nitrogen in their bodies by moving it not to their livers, but to their mouths!

How America could lose its allies | 2020 Election

What is NATO? And why is it still around?

What do you wish the presidential candidates would talk about? http://vox.com/ElectionVideos

For 150 years, the US avoided formal alliances. It occasionally went to war — fighting the War of 1812, the Spanish-American War, and World War I — but did so without entangling itself in promises to other countries. Then, after World War II, it abruptly changed course, and began to build a network of alliances unlike anything that had come before.

Over the next few decades, the US used those alliances to keep countries around the world close, and to fight Soviet expansion, by making a promise that it would go to war if any of its allies were ever attacked. After the Soviet Union fell, the initial purpose of those alliances was gone, but the US recommitted to them, signaling again and again that the central promise of those relationships was still in effect. It kept doing so for the next 25 years.

Then the US elected a leader who took America’s global relationships in a new direction. President Trump was skeptical that America’s network of alliances was still beneficial to the US. He began to distance the US from those alliances, raising doubts about whether America would actually follow through on the promise at the core of them if provoked. Some allies moved closer to Russia or China, both of whom had attempted to undermine America’s alliances.

Today, the future of those alliances is on the ballot in the US. One of the major presidential candidates in the 2020 election wants to return the US to its former status with its allies; the other finds its decades-old alliances costly and cumbersome. The world is waiting to see which vision Americans prefer.

This video is the sixth in our series on the 2020 election. We aren’t covering the horse race; instead, we want to explain the stakes of the election through the issues that matter the most to you. To do that, we want to know what you think the US presidential candidates should be talking about. Tell us here: http://vox.com/ElectionVideos

This Is Why Birds Are So Affected by Oil Spills

It takes a bit more than just soap and water to save a bird that has been in an oil spill, but the experts at International Bird Rescue are more than up for the challenge.

We have all seen images of birds affected by spills. Saving a bird that has been in an oil spill is a meticulous process to restore the incredible waterproofing capabilities of bird feathers so that the bird can be returned to the wild and survive.

We’ve been using our planet’s rivers, lakes and oceans to ship crude oil from place to place since the beginning of oil, and while this is an effective way to transport large quantities of petroleum, the method runs the risk of oil spills—events that have wreaked havoc on marine ecosystems.

Experts at International Bird Rescue aspire to rescue and rehabilitate the birds who have been victims of oil spills and the team has saved thousands of birds, cleaning and healing them to fly another day.

Find out exactly why oil spills are so damaging to seabirds in this ReWild.

Experts Disagree On Value Of Cleaning Oily Birds
https://www.npr.org/templates/story/story.php?storyId=128320107
“Since oil started gushing into the Gulf of Mexico over two months ago, we’ve all probably seen images of birds covered in black goo and of wildlife experts carefully cleaning, rehabilitating and finally releasing them back into the wild. It’s a small but very visible part of the huge story about the effects of all that oil on all kinds of animal life, and it’s a matter of debate.”

Waterbirds and a Changing Global Environment
https://www.bird-rescue.org/our-work/aquatic-bird-rehabilitation.aspx
“Many experts believe that critical hardships faced by pelicans, murres, and loons could be related to environmental shifts caused by warming oceans, pollution, collapsing fish stocks, and harmful algal blooms.”

King eider dies 16 years after rescue from oil spill
https://www.adn.com/anchorage/article/king-eider-dies-16-years-after-rescue-oil-spill/2012/10/15/
“It’s a big deal to know the duck lived for 16 years, at the far upper range of its life span, because so little data on the long-term survival of such birds exists, Holcomb said.
Rescuers also contend the recovery of the king eider offers at least anecdotal proof that the cost and effort of rehabilitating oiled birds pays off, something critics have long questioned.”

Imagine a distant future when humans reach beyond Earth, forge cities on planets thousands of light-years away, and maintain a galactic web of trade and transport. What would it take to make that leap? And where would we get enough energy to power that civilization? Fabio Pacucci explores the possibility of harnessing energy from a black hole to power a galactic civilization.
