There’s a good reason why stubbing your toe hurts so much

  • Stubbing your toe hurts so much because you’re slamming a tiny surface with a force equal to 2-3 times your bodyweight.
  • Then a bundle of nerve endings called nociceptors fire a danger signal to your brain.
  • Although it’s not pleasant, this pain might have helped your ancestors step carefully and avoid injury and infection.

Following is a transcript of the video.

Stubbing your toe hurts. It’s right up there with paper cuts and chapped lips. Annoying, minor injuries that hurt way more than they have any right to. But it turns out, there’s a good reason why stubbing your toe hurts so much.

When you stub your toe, you’re slamming it with a force equal to 2-3 times your body weight. That’s about the same force as a karate punch! And since your toe has a tiny surface area, that force can’t spread out. So the pain stays concentrated at the point of impact.

It’s the same reason it hurts more to step on the tiny, pointy end of a thumbtack than the wider, blunt end. But you don’t just feel an immediate shock like when you step on a thumbtack. There’s that aching throb that comes after. That’s because when you stub your toe, you’re actually hitting a bundle of special nerve endings called nociceptors. They all fire at once, blaring a danger signal.

But some signals travel faster than others. The faster, A-delta nociceptors fire the first wave of signal, which races at 20 m/s up thousands of densely-bundled nerve fibers and ultimately to your brain. That causes the sharp, sudden pain you feel at the moment of impact. But some nerve fibers called C nociceptors send a slower signal at only 2 m/s. So after a moment’s delay, a second wave of pain signals reach your brain. That’s the dull throbbing that lingers on.

You can find nociceptors all over your body, from your eyes to your bladder. But they’re concentrated at the highest densities in parts of your body you use to explore your environment, like your fingertips, and lips. That’s why accidents like paper cuts and chapped lips can also hurt more than they seem like they should. Now, your toe isn’t packed with as many nociceptors as your fingertips. But since there’s not much in the way of fat padding to cushion the blow it’s easy to set those unprotected nociceptors off. And that’s no coincidence.

Researchers suspect the pain we feel from mishaps like a stubbed toe might’ve saved our ancestors’ lives. Back before antibiotics, even the tiniest cut could mean a deadly infection. And feet, which were constantly in contact with dirty, bacteria-infested surfaces were particularly vulnerable. So people who had extra- sensitive feet might’ve been more careful about where they stepped. As a result, they’d be less likely to get infections and would live to pass on their genes.

So the next time you collapse to the floor, cradling your aching toe you can thank your great great great great great great grandpa for the privilege.

JPMorgan and Citigroup just closed bond desks for smaller trades in favor of algorithms. It’s another sign that robots are taking over.


bond trader, bond broker

  • Citi and JPMorgan in recent weeks closed down the teams on their corporate-bond trading desks that handle smaller sized bonds known as "odd lots." 
  • The margins on trading these smaller bonds were too thin to substantiate specific teams dealing the volume. Algorithms will now handle the trading of these bonds. 

Some of Wall Streets’ biggest corporate bond dealers are replacing humans with algorithms for a portion of their trades, another sign that the robot revolution is in full swing. 

Citigroup and JPMorgan both recently disbanded teams dedicated solely to trading small-sized corporate bond transactions, known as odd lots, according to people familiar with the matter. The teams dealt primarily with retail clients who typically deal in the smaller, less liquid bonds.  

Read more: A group of nearly 30 bond dealers is about to start sharing prices on a new platform, and it could shine a light on the market when it’s ‘riskier than ever’

At Citi, the responsibilities of eight traders who had been part of the corporate bond retail desk (six in investment grade and two in high yield) were subsumed into the firm’s electronic bond trading platform in within the past few weeks, according to two people with knowledge of the matter. That means the handling of the odd-lot bonds will be managed by algorithms instead of humans. 

At least two of the traders, Keith McCluskey and Jim Berry, have left Citigroup. It’s not clear what has happened to the other six. The traders didn’t respond to requests for comment sent through LinkedIn. 

We have significantly enhanced our infrastructure and trading capabilities to create a better experience for clients,” a Citi spokeswoman said in a statement.

The path to the change was paved in September 2018, when Citi reorganized the corporate bond trading team to bring institutional trading teams and the retail trading teams under one leadership.

At JPMorgan, a team of less than five people who had been trading in odd lot corporate bonds, got absorbed into the larger credit trading group over the last few weeks, according to two people with knowledge of the move. The bank decided that it could still serve clients just as well by disbanding the group and steering the volumes onto its electronic trading infrastructure, the people said. Most of the traders are still at JPMorgan. 

A bank spokesman declined to comment further. 

The moves come as big banks are trying to cut-costs and slash unprofitable business lines, particularly in their trading units. JPMorgan and Citi were thought to be the last two dealers to have dedicated teams for odd-lot trades. 

Mike Nappi, vice president of investment grade corporate bond trading at Eaton Vance, told Business Insider he estimates 75-80% of trading on bonds under $1 million is handled by machines. Unless a firm is able to do a high volume of odd-lot trades — he cited Charlotte-based Millennium Advisors as an example — the profit margins are too thin to maintain a large human team. 

"It’s a trend we’re going to continue to see over the next few years," Nappi said. "That is where the market is headed for those types of trade sizes, no question."

And while the majority of algorithms operate in bonds under $1 million, the machines are getting more advanced. Nappi said he believes some dealers have algos that have permission to operate in deals as high as $2 million.

Only at the $5 million mark do the algos completely disappear, he added. Automating deals above that mark gets tricky, Nappi said, as firms are concerned about filling up the space on their balance sheet with large bonds they might not be able to move.

Nappi said there is a myth most traders aren’t open to automation in their space because they feel they’ll be out of a job. While it’s true that just like in the general economy, machines will reduce the number of some jobs, it will also streamline others.

With algorithms handling smaller deals, traders will be freed up to handle bigger trades. 

"I think most traders would welcome that stuff going electronic because there is plenty to do away from the small odd-lot electronic trade," Nappi said. "If I can spend more time with the difficult trades, that is great. If I have to hand trade 100 odd lots, that is just going to take time."

A recipe for beating the record of most-calculated digits of pi


Editor’s note: Today, March 14, is Pi Day (3.14). Here at Google, we’re celebrating the day with a new milestone: A team at Google has broken the Guinness World RecordsTMtitle for most accurate value of pi.

Whether or not you realize it, pi is everywhere you look. It’s the ratio of the circumference of a circle to its diameter, so the next time you check your watch or see the turning wheels of a vehicle go by, you’re looking at pi. And since pi is an irrational number, there’s no end to how many of its digits can be calculated. You might know it as 3.14, but math and science pros are constantly working to calculate more and more digits of pi, so they can test supercomputers (and have a bit of healthy competition, too).

While I’ve been busy thinking about which flavor of pie I’m going to enjoy later today, Googler Emma Haruka Iwao has been busy using Google Compute Engine, powered by Google Cloud, to calculate the most accurate value of pi—ever. That’s 31,415,926,535,897 digits, to be exact. Emma used the power of the cloud for the task, making this the first time the cloud has been used for a pi calculation of this magnitude.

Here’s Emma’s recipe for what started out as a pie-in-the-sky idea to break a Guinness World Records title:

Step 1: Find inspiration for your calculation.

When Emma was 12 years old, she became fascinated with pi. “Pi seems simple—it starts with 3.14. When I was a kid, I downloaded a program to calculate pi on my computer,” she says. “At the time, the world record holders were Yasumasa Kanada and Daisuke Takahashi, who are Japanese, so it was really relatable for me growing up in Japan.”

Later on, when Emma was in college, one of her professors was Dr. Daisuke Takahashi, then the record holder for calculating the most accurate value of pi using a supercomputer. “When I told him I was going to start this project, he shared his advice and some technical strategies with me.”

Step 2: Combine your ingredients.

To calculate pi, Emma used an application called y-cruncher on 25 Google Cloud virtual machines. “The biggest challenge with pi is that it requires a lot of storage and memory to calculate,” Emma says. Her calculation required 170 terabytes of data to complete—that’s roughly equivalent to the amount of data in the entire Library of Congress print collections.


Step 3: Bake for four months.

Emma’s calculation took the virtual machines about 121 days to complete. During that whole time, the Google Cloud infrastructure kept the servers going. If there’d been any failures or interruptions, it would’ve disrupted the calculation. When Emma checked to see if her end result was correct, she felt relieved when the number checked out. “I started to realize it was an exciting accomplishment for my team,” she says.

Step 4: Share a slice of your achievement.

Emma thinks there are a lot of mathematical problems out there to solve, and we’re just at the beginning of exploring how cloud computing can play a role. “When I was a kid, I didn’t have access to supercomputers. But even if you don’t work for Google, you can apply for various scholarships and programs to access computing resources,” she says. “I was very fortunate that there were Japanese world record holders that I could relate to. I’m really happy to be one of the few women in computer science holding the record, and I hope I can show more people who want to work in the industry what’s possible.”

At Google, Emma is a Cloud Developer Advocate, focused on high-performance computing and programming language communities. Her job is to work directly with developers, helping them to do more with the cloud and share information about how products work. And now, she’s also sharing her calculations: Google Cloud has published the computed digits entirely as disk snapshots, so they’re available to anyone who wants to access them. This means anyone can copy the snapshots, work on the results and use the computation resources in less than an hour. Without the cloud, the only way someone could access such a large dataset would be to ship physical hard drives. 

Today, though, Emma and her team are taking a moment to celebrate the new world record. And maybe a piece of pie, too. Emma’s favorite flavor? “I like apple pie—not too sweet.”

Youth will strike worldwide for climate action on Friday


On Friday, March 15, thousands of protests are planned across the globe with young people skipping school to protest against environmental inaction by their governments.  This event is being organized by Fridays for Future globally and by US Youth Climate Strike in the US.

While the Global Climate Strike’s main day of protest is this Friday, March 15th, many protests are scheduled to continue occurring weekly or monthly (you can find them color-coded by frequency on this map).  Global youth intend to broadcast their exhortation to climate action to the people in charge of our planet’s future, until governments act in a suitably strong manner to fix this urgent problem.

The movement’s genesis

The “Fridays for Future” movement was started in 2018 by then-15-year-old Greta Thunberg, who skipped school to sit on the steps of Swedish parliament.  She has been doing the same every Friday since last August.  Her reasoning is: Why bother going to school to secure your future when those with political and economic power are currently acting to dismantle that future?

In addition to her weekly protests at Swedish parliament, she made international headlines when she recently confronted the world’s elites at the World Economic Forum in Davos.  Many applauded her precociousness, including those who she confronted, though commitments towards action were noticeably absent.

The message in Davos was that children do not have the wealth or political power to effect change themselves, so it is the responsibility of those who do have that power to act sensibly and not ruin the living systems which these children’s future relies on.

Why it’s necessary

Climate change is different from other problems because we cannot negotiate our way out of it.  On the other side of the negotiation table is physics, and physics is not known for budging when asked politely to do so.  It has set a time limit, an ultimatum, and we humans have no choice but to respect that ultimatum and act accordingly.

After decades of science continuing to confirm that this problem is bad, just yesterday we learned that, even if the world were to go zero-carbon, large Arctic temperature rises are likely to happen regardless.  Soft action is not going to solve this problem.  If zero carbon isn’t enough, then the world needs to go negative carbon (actively sequestering more carbon than we emit), and it needs to do so now.  When mass extinction of species is at stake, drastic and immediate action is called for.

And despite the Paris Agreement and subnational organizations like the US Climate Alliance picking up where their federal government is slacking off, very few countries are taking action.  The world needs stronger action, and it needs it now.  Otherwise, these kids will inherit a much worse future from their parents.

And what are the kids to do?  For the most part they unfortunately do not have the right to vote on issues that will affect them for the entire rest of their lives – the better part of a century – and are instead beholden to the inaction of the rest of the voting populace.

So they are expressing their voice in the best way that they can.  Unfortunately, decisions are being made for them by people who, in their wisdom, have led us into this situation and seem to have no intention of leading us out.  And the younger generations are the ones who will have to suffer the effects of those decisions

Resistance to the protests

As is the case with many protests, those who are uninterested in responsible action to save the climate or who do not respect the democratic process have already started to write off the message of this protest with banal statements along the lines of “they’re just trying to get out of school.”  But this is lazy reasoning.  This protest has a clear message, so engage with that message.  To refuse children the opportunity to use one of few methods they have to express their voice is authoritarian and disrespectful to democratic values.

In a piece in the LA Times, climate communicator Bill McKibben and student climate activist Haven Coleman liken this to civil rights protests in the 60s.  Martin Luther King called for a student strike and said “don’t worry about your children…they’re gonna be all right…For they are doing a job not only for themselves but for all of America and for all mankind.”  King, in his Letter from Birmingham Jail, also lamented those who are “more devoted to ‘order’ than to justice; who prefer a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly say: ‘I agree with you in the goal you seek, but I cannot agree with your methods of direct action’.”  To deny these youth their method of action is to deny them justice.

Indeed this action is just, and necessary. Opponents of action will say that these kids should spend their time getting educated instead of skipping school.  But if these individuals stand against climate action, then perhaps they could gain a little education from these kids.  We’ve known for nearly 50 years that this is happening, yet little has been done in that time to confront the issue.  The generation which has been alive all that time and failed to act – or at least those within it who argued in favor of inaction – has lost their moral authority to condescend to children on this issue.

Blame and fault

It is tempting to think about climate issues as somebody else’s problem.  The individual suggests that it’s not their fault, it’s the corporations.  The corporations suggest that it’s not their fault, it’s consumer demand.  Governments suggest that it’s not their fault, it’s public opinion.  Media doesn’t feel like reporting on it because it doesn’t get them enough clicks.  Everybody wants to pass the buck so they can just move along without thinking about it.

And during all of this, the kids, who are only just learning about the world they’ve been born into, see a bunch of “adults,” who all caused this problem, bickering and pointing fingers instead of taking action.

The long and short of it is that this is everyone’s problem, and we’re not going to solve it without everyone’s action.

Individuals must act to be responsible in their consumption.  Corporations must act in making their products in the least environmentally damaging way possible.  Governments must act in aligning incentives such that pollution is no longer ignored, or worse yet incentivized, and to guide their populations towards a sustainable future through large-scale collective action.  Media must correctly describe the severity of the problem, give it the appropriate amount of coverage, and stop letting fossil-funded lobbyists who deny science and work to harm the world control the conversation.  Older generations must act by sustainably using resources so as not to steal them from future generations, or leave the world in a worse way than they came into it.  Everyone needs to consider the planet we all share with every action they take.

And kids must act by holding older generations to task in whatever way they can with the limited power they have.

This strike on Friday is one attempt at action.  Thank you, youth of the world.  Hopefully we’ll see more of this.  And maybe adults will finally get it together to solve the biggest, most urgent problem the world has ever faced.

Molten Hot Lava Versus Dry Ice, Scientist Pours One Out To See What Happens And It’s Awesome


I don’t really spend anytime whatsoever thinking about dry ice or lava. For starters, I grew up and Florida and the only times I’ve ever been close to volcanoes have been in Panama, Costa Rica, and Iceland. Lava just isn’t something I find myself thinking about but this science experiment definitely piqued my curiosity.

Likewise, I cannot recall a time when I needed dry ice. I’m not sure I could even tell you where to buy dry ice if you needed to. I assume the grocery store would carry it but that could be wrong.

The last time I even saw the stuff was when I loaned my parents my YETI Cooler when they were on a week-long road trip and they loaded it up with glass bottles of juice + dry ice not realizing that the cooler keeps regular ice frozen for a week. The end result was pretty hilarious. I got some panicked text messages from them about how everything in the cooler exploded because it had gotten *TOO COLD* and the glass shattered. Let that be a lesson to never load up your YETI with dry ice.

Let’s start with acknowledging that dry ice is frozen carbon dioxide, and the temperature of dry ice is -109.3 degrees Fahrenheit or -78.5 degrees Celsius. The temperature of molten lava is somewhere between 1,300 to 2,200 F or 700 and 1,200 degrees Celsius….So, who ya got?

The YouTube channel PressTube put together this clip where they create lava and then dump it over a bowl of dry ice.

As my colleague Paul pointed out, this could easily be viral marketing for the White Walkers battle in the final season of HBO’s Game of Thrones. The fire barely puts up a fight. It releases that haunting sound and then turns into some pretty badass art though.

If I was rich and threw lots of fancy house parties I’m fairly certain that I’d just hire YouTubers like this to come to my parties and perform outrageous science experiments for my guests. If you’re not spending your wealth on extravagant shit like that then you honestly have no business being rich.


If you think the $1,000 iPhone XS is too cheap, don’t worry — this company made a $24,500 iPhone with a mechanical clock on its back



  • A Russian company called Caviar that makes luxury versions of existing smartphones has had its way with the iPhone XS and XS Max.
  • The Caviar iPhone XS Grand Complication Skeleton Diamond Edition is dressed in black titanium, gold, 252 diamonds, and it has a mechanical clock on its back. 
  • The cheapest of Caviar’s Diamond Edition Grand Complication iPhones is the 256GB iPhone XS at $23,320. The most expensive is the 512GB iPhone XS Max at $24,460.

Custom, multi-thousand-dollar iPhones adorned in gold, diamonds, and rare animal skins are nothing new, but the Caviar iPhone XS Grand Complications Skeleton Diamond Edition is a little different.

Indeed, there’s a mechanical clock right in the middle of its back.

The Caviar iPhone XS Grand Complication Skeleton Diamond Edition is available in both the iPhone XS and XS Max, and in the 256GB and 512GB storage options. 

As you’d expect, delivery is free, and the transaction is accompanied by a "personal consultant."

One thing that’s somewhat questionable when you’re spending that much on a product is the one-year warranty. That’s it? One year? And that’s just for the electronics — the outer-dressing and coverings are only warrantied for 30 days. 

Regardless, check out this $24,500 iPhone:

How Paying Your Credit Card Minimum Puts You in a Debt Spiral


Image: Ludde Lorentz on Unsplash

If you have a credit card, you should, theoretically, know how missing a payment or paying off less than your total balance each month can lead to a debt spiral. The interest rate on credit cards is very high compared to other financial products, and it compounds when you don’t pay your balance off in full each month.

And credit cards make it easy to fall into that debt spiral. One way they do this is that your issuer will display the “minimum balance due” each month prominently on your bill/online account, and if you don’t know any better and continually pay off just the minimum, you can end up owing a lot more money over the long term.

CNBC explains how paying off just the minimum each month can add up quickly:

The average household with credit card debt owes roughly $5,700, while those under the age of 35 owe $5,808. If you only paid the minimum on a $5,000 debt at the current average interest rate [which is over 17 percent], you’d be in debt for over 18 years and pay roughly $11,400 in interest.

As Lifehacker previously wrote, some issuers’ minimum payment is as little as one percent of your total balance. And while they say this gives you, the consumer, more flexibility, it’s really just a way for them to profit off of you. (That said, if you’re in a period of financial strain, a minimum balance does allow you to keep up your credit score/keep creditors off of your back until you get back on your feet.)

That’s why it’s important to think of a credit card as a tool, and use it as a means to an end. It’s easy to spend more than you can afford, but you should only charge as much as you can pay off in a single month. Credit card companies are counting on the fact that you won’t.

This is one of the black boxes that could unlock the cause of the Ethiopian Airlines Boeing 737 Max crash (BA)


Ethiopia Airlines ET302  Flight Data Recorder

  • Crash investigators released the first picture of the black boxes from Ethiopian Airlines Flight ET302.
  • The photo, of the Boeing 737 Max 8 airliner’s mangled flight data recorder, was published by the French government on Thursday. 
  • Flight ET302’s flight data recorder and cockpit voice recorder were recovered on Monday and flown to Paris on Wednesday. 

Crash investigators released the first picture of the black boxes from Ethiopian Airlines Flight ET302. The photo, of the Boeing 737 Max 8 airliner’s mangled flight data recorder, was published by the French government on Thursday. 

Flight ET302’s black boxes, a colloquial term used to describe an aircraft’s cockpit voice recorder (CVR) and flight data recorder (FDR), were recovered on Monday.

The recorders could provide investigators with key clues that may reveal the cause of the crash and ultimately solve the mystery of what’s wrong with the Boeing 737 Max. 

With US National Transportation Safety Board assisting in the investigation of the Renton, Washington-built plane, it was thought the black boxes would be sent to the US. 

Instead, Ethiopian authorities handed over the recorders to the BEA, France’s well-respected aviation investigation agency. 

Read more: Trump announces all Boeing 737 Max jets are immediately grounded following its 2nd crash in 5 months.

According to the National Transportation Safety Board, modern aircraft FDRs are required by law to records at least eight key parameters including time, altitude, airspeed, and the plane’s attitude. However, more advanced recorders can monitors more than 1,000 parameters.

Ethiopian Airlines Boeing 737 Max 8 crashOlder units used magnetic tape to record data, however, modern FDRs use digital technology that can record as much as 25 hours.

The cockpit voice recorder does just that. It records what’s going on in the cockpit including radio transmissions, background noise, alarms, pilot’s voices, and engine noises for as long as two hours. 

Both recorders are stored in reinforced shells that are designed to survive 30 minutes in 2000-degree Fahrenheit heat and be submerged in 20,000 feet of water. 

On Sunday, Ethiopian Airlines Flight ET302 crashed shortly after taking off from Addis Ababa Bole International Airport. The incident, which killed all 157 passengers and crew on board, marked the second nearly-brand new Boeing 737 Max 8 airliner to crash in four months. Lion Air Flight JT610 crashed after taking off from Jakarta, Indonesia on October 28. 

Regulatory agencies and airlines in the more than 50 countries around the world including the US, have grounded the airliners. The Boeing 737 Max entered service in 2017. There are currently 371 of the jets in operation.

Why Digital Detoxes Don’t Work


Being without your phone is a luxury these days. If you can manage it, you are either on vacation, or you have a staff to handle all your digital grunt work. For the rest of us, tech is both a distraction and a necessity. And we are powerless to do much about that.

What is the point of a detox?

The original point of a detox was that if you literally have a toxic substance in your body, you need to get rid of it. Our bodies do not accumulate a substance called “digital,” so this concept does not apply.

A digital detox is more like a crash diet. You eat nothing (or, like, just juice) for a time, with the hopes that you get skinnier during that time. You may hope that you’ll get out of the habit of eating high-calorie food (or checking your phone all the time). But really, it’s just a way of assuaging guilt before you go back to your old habits.

“Detoxes” only feel good because they’re vacations

There are two ways to do a digital detox. One is to simply use your phone less while living your normal life, which is basically impossible, because your normal life probably depends a lot on your phone.

If you are rich, you can detox by taking a special digital detox vacation. If you are not, you may still find that a regular vacation leaves you without the use of your phone (shout out to that campground in the mountains last year where my phone had no signal all weekend). And for the rest of us, there’s always the staycation option: tell everybody we’re going offline, uninstall some apps, and try to keep busy in other ways. Invite people over for board games.

If you enjoyed your digital-detox resort, or your weekend of board games, you may come back with stories about how present and connected you felt, how much better you slept. News flash: You had fun because you were on vacation. You gave yourself a bunch of things to do that were more fun than scrolling through Twitter on the toilet. There’s no way to apply this in real life: You can’t transport yourself to Aruba for ten minutes when you’re waiting for the bus. Your friends will not come over for board game night every time you decide you are bored.

You can’t return to a phone-free life

During the food/juice type of detox, the allure is that you’ll feel so great you won’t even miss the junk food; you’ll eat cucumbers for breakfast every day for the rest of your life now that you’ve pushed the reset button.

But there’s no equivalent way to return from a digital detox. You can turn off most of your notifications, and get in the habit of putting your phone down more often, but it’s not like you can actually live a phone-free life.

“But people used to!” say the naysayers. Really, though. Are you going to buy fold-out road maps and only know if there’s a traffic jam if it’s bad enough to get reported on the local news? Get a paper dictionary? Buy an encyclopedia from a traveling salesman? Rescue the next Yellow Pages that gets dumped in your front yard, and hope that the businesses you might need to find actually still pay for advertising in it? Give the babysitter the number of the restaurant where you’ll be on date night, so they can ask the staff to get a message to you in case of an emergency? This isn’t a sustainable solution.

FOMO is a feature, not a bug

The anxiety we feel from constantly checking/wanting to check our phone is the FOMO (fear of missing out) that’s built in to the app and phone experience itself. It’s a design feature, not a flaw. The phone will always keep trying to induce it in us. We want to step away—to detox but when we go back, we will feel it again. There is no healthy, anxiety-free way to use a smartphone.

Phone addiction is not an individual problem, and we are fools to think any personal action is going to make a dent in the issue. You can’t change your relationship with technology because the technology and the world are still the same as they were.

It would be great if we could be more intentional about the way we use our phones, but the apps aren’t on board with this plan. Facebook doesn’t want us to be able to check the location of a party we RSVP’d to without showing us 10 other events and a hundred other snippets of our friends’ lives. Twitter doesn’t want us to tweet something without seeing everybody else’s tweets first. Even checking messages from a boss or co-worker, you can’t do that without Slack stage-winking at all these unread messages over here. Your phone shows you either your home screen or your most recent app when you pick it up; neither Apple nor Google has any interest in putting, say, a to-do list on the screen by default and hiding all the distracting apps. It doesn’t benefit them.

So you can stay away from technology a little bit at a time, for now. You can be all high and mighty about eschewing Facebook while you leave all the emotional labor to your wife. But there is no healthy way to use your phone, and nothing you can discover during a digital detox that will change the fact that mega-corporations use your attention—yes, yours—as fuel for stockholders. So take a “detox” if you like, but be honest with yourself: It’s just a vacation.

Let’s forget about folding displays for a bit and admire Insta360’s folding camera!


The idea behind the Evo’s design is a simple, but unique one. 3D cameras and 360° cameras have one thing in common… the presence of at least two lenses. Where those lenses face in relation with each other, and the type of lens determines the kind of media you capture. Lenses that sit side by side (with a rough distance of 2.5 inches between them) can capture two different channels corresponding to the left and right eye, creating a sense of depth, and therefore a 3-dimensional video or image. Lenses (usually at least 180° fisheye) that face in opposite directions can capture an entire scene in 360 degrees, allowing you to create videos or images you can look around in and immerse yourself into. The Insta360 Evo simply creates a mechanism in which these two lenses can fold to either face in the same direction or the opposite, allowing the camera to alternate between shooting in 3D and in 360°.

The Evo can record 3D 5K/30fps video (or 18-megapixel stills) with a 180-degree field of view, viewable using a VR headset that comes in the box, or an innovative HoloFrame case that sits on your phone, turning your phone’s screen into a 3D display. Fold the cameras to face opposite each other and the camera captures 360° videos and stills that you can view in your VR headset, even looking around to see things behind, beside, above or below you.

What’s even more remarkable about the Evo is its ability to not just record, but also stabilize video. Using its 6-axis gyroscopic stabilization system, Evo’s videos are immersive, crisp, and jitter free. The FlowState stabilization system even allows the Evo to capture time-lapses that are incredibly smooth. Whether you’re walking on the footpath or on a bumpy trail, the Evo can capture videos without needing an external gimbal or stabilizer (the gimbal would end up getting captured in 360° videos too). A simple flip/fold mechanism allows you to transition between shooting in 3D and shooting in VR, allowing you to create fully immersive video content, and the Evo even packs kits, headsets, and cases that let you and your audience properly view the content you’ve created!
