Kid’s seemingly correct answer on a math test has the Internet up in arms

A simple answer raises plenty of questions.

Memories of testing like this gets people fired up.

It doesn't take much to cause everyone on the internet to go a little crazy, so it's not completely surprising that an incorrect answer on a child's math test is the latest event to get people fired up.

The test in question asked kids to solve "5 x 3" using repeated addition. Under this method, the correct answer is "5 groups of 3," not "3 groups of 5." The question is typical of Common Core but has many questioning this type of standardized testing and how it affects learning.

After an image of the test was uploaded to Imgur, many took to voicing their opinions on both sides of the argument. One commenter took up the side of the student, saying, "As an instructor: fuck it. I am actually happy when I see people finding alternative ways to solve the problems." Another said, "Actually the teacher is correct. 5*3 means 5 times the number 3, or 3+3+3+3+3. Understand, we are not in the room when it was TAUGHT."

One thing we can all agree on is about "5+5+5" is that it equals another example of how much people on the internet love to argue.

Did you get it wrong too?

Science

In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea.

In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot.

The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.

16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.

Treuer initially set out to locate the large placard that marked the plot — and failed.

"It's a huge sign, bright yellow lettering. We should have been able to see it," Treuer says. After wandering around for half an hour with no luck, he consulted Janzen, who gave him more detailed instructions on how to find the plot.

When he returned a week later and confirmed he was in the right place, Treuer was floored. Compared to the adjacent barren former pastureland, the site of the food waste deposit was "like night and day."

"It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems," he explains.

The area was so thick with vegetation he still could not find the sign.

Treuer and a team of researchers from Princeton University studied the site over the course of the following three years.

The results, published in the journal "Restoration Ecology," highlight just how completely the discarded fruit parts assisted the area's turnaround.

The ecologists measured various qualities of the site against an area of former pastureland immediately across the access road used to dump the orange peels two decades prior. Compared to the adjacent plot, which was dominated by a single species of tree, the site of the orange peel deposit featured two dozen species of vegetation, most thriving.

In addition to greater biodiversity, richer soil, and a better-developed canopy, researchers discovered a tayra (a dog-sized weasel) and a giant fig tree three feet in diameter, on the plot.

"You could have had 20 people climbing in that tree at once and it would have supported the weight no problem," says Jon Choi, co-author of the paper, who conducted much of the soil analysis. "That thing was massive."

Recent evidence suggests that secondary tropical forests — those that grow after the original inhabitants are torn down — are essential to helping slow climate change.

In a 2016 study published in Nature, researchers found that such forests absorb and store atmospheric carbon at roughly 11 times the rate of old-growth forests.

Treuer believes better management of discarded produce — like orange peels — could be key to helping these forests regrow.

In many parts of the world, rates of deforestation are increasing dramatically, sapping local soil of much-needed nutrients and, with them, the ability of ecosystems to restore themselves.

Meanwhile, much of the world is awash in nutrient-rich food waste. In the United States, up to half of all produce in the United States is discarded. Most currently ends up in landfills.

"We don't want companies to go out there will-nilly just dumping their waste all over the place, but if it's scientifically driven and restorationists are involved in addition to companies, this is something I think has really high potential," Treuer says.

The next step, he believes, is to examine whether other ecosystems — dry forests, cloud forests, tropical savannas — react the same way to similar deposits.

Two years after his initial survey, Treuer returned to once again try to locate the sign marking the site.

Since his first scouting mission in 2013, Treuer had visited the plot more than 15 times. Choi had visited more than 50. Neither had spotted the original sign.

In 2015, when Treuer, with the help of the paper's senior author, David Wilcove, and Princeton Professor Rob Pringle, finally found it under a thicket of vines, the scope of the area's transformation became truly clear.

"It's a big honking sign," Choi emphasizes.

19 years of waiting with crossed fingers had buried it, thanks to two scientists, a flash of inspiration, and the rind of an unassuming fruit.

Knowing the differences between 'delayed drowning' and 'dry drowning' could save a life

It can be easy to miss the signs.

Important summer tips.

In 2008, a young boy named Johnny Jackson went swimming and accidentally swallowed some water.

He had a short coughing fit, toweled off, and then went home. No big deal.

Or so his parents thought.

A few hours later, after going down for a nap, Johnny passed away.

In 2014, a toddler named Ronin came frighteningly close to the same fate. He slipped briefly into a pool before being pulled to safety by his mother. Ronin was shaken up but seemed fine.

Later that night, he lay stretched out in an ambulance as it screamed toward the hospital, where he arrived just in time.

Stories like these have resulted in an outburst of news coverage around what's being referred to as "dry drowning." But that's a bit of a misnomer.

Since we're entering the season of pool parties and beach trips, here are a few things you really need to know about what actually happened to Ronin and Johnny.

First, there is a difference between dry drowning and delayed drowning.

With dry drowning, water never enters the victim's lungs. Rather, it causes the vocal chords to spasm and shuts off airways without actually filling the lungs with water. Otherwise, it looks a lot like normal drowning because it occurs in real time and causes asphyxiation.

Delayed drowning, sometimes called secondary drowning, is a bit different. In cases like Ronin and Johnny's, water gets into the lungs in small amounts — not enough to disable breathing right away. Instead, it sits there and inhibits the lungs' ability to oxygenate blood. From there, the victim starts to have more and more trouble breathing over the course of several hours.

Second, drowning doesn't look the way it does in the movies.

Whether you're dealing with normal, dry, or delayed drowning, don't expect a dramatic scene full of thrashing, coughing, and yelling.

According to Dr. Anna Mendenhall of the Children's Physicians Medical Group, 9 out of 10 children who drown do so even though they were being supervised by a parent because it's so easy to miss the signs.

Here's what you need to look for, even hours after you've left the pool or beach:

• Difficulty breathing, coughing, chest pain, or throwing up. Look for rapid and shallow breaths, nostril flaring, or a pronounced gap in the ribs when breathing. These are all signs a child is working too hard to get oxygen.
• Extreme tiredness. Big-time fatigue can be a sign that the brain isn't getting enough oxygen.
• Any odd change in behavior. Kids in the beginning stages of delayed drowning may be really cranky, argumentative, or combative.
• Odd physical changes. Look out for blue lips or pale skin.

Most likely these symptoms will go away over time. But if they don't or they get worse, you might want to call your pediatrician on the way to the emergency room.

And the best way to watch for drowning in the moment? Get in the pool with your kids and stay within an arm's reach. It's the only way to make sure you don't miss anything.

Third, don't panic. Delayed and dry drownings combined make up only 1% to 2% of all drowning incidents.

There's no getting around it. This is really scary stuff, especially to a parent.

I have a 2-month-old daughter, and my first reaction to all of this is to literally never let her near a swimming pool. Ever.

But as scary as they are, these unusual cases are just that — unusual.

It's a really good idea teach your kids about basic water safety and get them comfortable in the pool with swim lessons at an early age (experts say 4 or 5 is a good age to start). But I'll say it again:

The single best thing you can do to protect a child from drowning — wet, dry, or otherwise — is to get in the pool with them.

As long as you're prepared, pools can be great for fun things like throwing your children! Photo from Thinkstock.

At least until they're old enough to be embarrassed by your presence.

Parents who grew up in the '70s and '80s remember the experiences that blow their kids' minds

Kids were tougher then for a reason.

Island School Class, circa 1970s.

Parents, do you think your child would be able to survive if they were transported back to the '70s or '80s? Could they live at a time before the digital revolution put a huge chunk of our lives online?

These days, everyone has a phone in their pocket, but before then, if you were in public and needed to call someone, you used a pay phone. Can you remember the last time you stuck 50 cents into one and grabbed the grubby handset?

According to the U.S. Federal Communications Commission, roughly 100,000 pay phones remain in the U.S., down from 2 million in 1999.

Do you think a 10-year-old kid would have any idea how to use a payphone in 2022? Would they be able to use a Thomas Guide map to find out how to get somewhere? If they stepped into a time warp and wound up in 1975, could they throw a Led Zeppelin album on the record player at a party?

Another big difference between now and life in the '70s and '80s has been public attitudes toward smoking cigarettes. In 1965, 42.4% of Americans smoked and now, it’s just 12.5%. This sea change in public opinion about smoking means there are fewer places where smoking is deemed acceptable.

But in the early '80s, you could smoke on a bus, on a plane, in a movie theater, in restaurants, in the classroom and even in hospitals. How would a child of today react if their third grade teacher lit up a heater in the middle of math class?

Dan Wuori, senior director of early learning at the Hunt Institute, tweeted that his high school had a smoking area “for the kids.” He then asked his followers to share “something you experienced as a kid that would blow your children’s minds.”

A lot of folks responded with stories of how ubiquitous smoking was when they were in school. While others explained that life was perilous for a kid, whether it was the school playground equipment or questionable car seats.

Here are a few responses that’ll show today’s kids just how crazy life used to be in the '70s and '80s.

First of all, let’s talk about smoking.

Want to call someone? Need to get picked up from baseball practice? You can’t text mom or dad, you’ll have to grab a quarter and use a pay phone.

People had little regard for their kids’ safety or health.

You could buy a soda in school.

Things were a lot different before the internet.

Remember pen pals?

A lot of people bemoan the fact that the children of today aren’t as tough as they were a few decades back. But that’s probably because the parents of today are better attuned to their kids’ needs so they don't have to cheat death to make it through the day.

But just imagine how easy parenting would be if all you had to do was throw your kids a bag of Doritos and a Coke for lunch and you never worried about strapping them into a car seat?

The haunting final messages people have received from significant others and the deceased

Every relationship has a final text.

"Why does it sound like you're leaving?"

In every relationship we'll ever have, there's going to be a final conversation. Before the digital age, these interactions were usually face-to-face or over the telephone and could only be recorded in our memories. But now, just about every relationship leaves a paper trail of text messages, social media interactions, and voice messages. Sometimes the final communication is a heated breakup, and other times, it's a casual interaction shortly before a person's death.

Now, there's a blog that collects these haunting final messages. The Last Message Received contains submissions of the last messages people received from ex-friends or ex-significant others as well as from deceased friends and relatives. Here are some of the blog's most haunting posts.

"My good friend's dad died around Thanksgiving. Two weeks later he drank himself to death."

"This is the last text I got from my mom before she died of Stage IV brain cancer at the age of 53. It left her completely paralyzed on the left side of her body, hence the typos in the texts. What she was saying was, 'You're missing music therapy.' Almost as good as Good Friday church giggles.' A few years prior to this, we went to the Good Friday service at our church. The choir was absolutely horrendous and couldn't sing whatsoever. She and I sat there, in the most serious, somber church service of all, laughing hysterically, unable to stop for the life of us. She sent me this text while she was in hospice and I was at school."

"This happened a few months back. He was my best friend and my boyfriend of 7 years. He stuck with me when I fell pregnant at 16 after I was raped. He became an actual dad to my son. He was my everything. A few months before this message, things started to change, we drifted apart and he was telling my 5 year old son to lie to me about his whereabouts. One night he beat me, I ended up in hospital for a few days. He begged for forgiveness, I stayed. It happened again a few days later, he was at work when I text him. I took my son and left. This is the last text I received from him. I heard last week that he's just been sent to prison for crimes involving violence and drugs. I hope he gets the help he needs."

"My dad died 6 weeks later flying the plane in this picture."

"The last text he sent me. The next day I got a call from his daughter that he was still very much with his wife and I wasn't the only one he was cheating on her with."

"She had sent me a message earlier asking me not to contact her anymore. I woke up to one last message. We'd dated for 3.5 years and when I came out as trans, the relationship fell apart. I still think about and miss her every day."

"I sent this to my grandpa on thanksgiving. Two days later he unexpectedly had a heart attack and passed. He was my favorite person in the world and nothing has been the same since. I refuse to delete this message."

"I would have fallen in love with her if distance and timing hadn't gotten in the way. I'm ignoring her because I need to let her move on."

The oldest whales on the planet are more ancient than 'Moby-Dick' and have the harpoons to prove it

Wow... just wow.

You're probably familiar with the literary classic "Moby-Dick."

But in case you're not, here's the gist: Moby Dick is the name of a huge albino sperm whale.

(Get your mind outta the gutter.)

There's this dude named Captain Ahab who really really hates the whale, and he goes absolutely bonkers in his quest to hunt and kill it, and then everything is awful and we all die unsatisfied with our shared sad existence and — oops, spoilers!

OK, technically, the narrator Ishmael survives. So it's actually a happy ending (kind of)!

Basically, it's a famous book about revenge and obsession that was published back in 1851, and it's really, really long.

It's chock-full of beautiful passages and dense symbolism and deep thematic resonance and all those good things that earned it a top spot in the musty canon of important literature.

There's also a lot of mundane descriptions about the whaling trade as well (like, a lot). That's because it came out back when commercial whaling was still a thing we did.

In fact, humans used to hunt more than 50,000 whales each year to use for oil, meat, baleen, and oil. (Yes, I wrote oil twice.) Then, in 1946, the International Whaling Commission stepped in and said "Hey, wait a minute, guys. There's only a few handful of these majestic creatures left in the entire world, so maybe we should try to not kill them anymore?"

And even then, commercial whaling was still legal in some parts of the world until as recently as 1986.

And yet by some miracle, there are whales who were born before "Moby-Dick" was published that are still alive today.

What are the odds of that? Honestly it's hard to calculate since we can't exactly swim up to a bowhead and say, "Hey, how old are you?" and expect a response. (Also that's a rude question — jeez.)

Thanks to some thoughtful collaboration between researchers and traditional Inupiat whalers (who are still allowed to hunt for survival), scientists have used amino acids in the eyes of whales and harpoon fragments lodged in their carcasses to determine the age of these enormous animals — and they found at least three bowhead whales who were living prior to 1850.

Granted those are bowheads, not sperm whales like the fictional Moby Dick, (and none of them are albino, I think), but still. Pretty amazing, huh?

This bowhead is presumably in adolescence, given its apparent underwater moping.

This is a particularly remarkable feat considering that the entire species was dwindling near extinction.

Barring these few centenarian leviathans, most of the whales still kickin' it today are between 20 and 70 years old. That's because most whale populations were reduced to 10% or less of their numbers between the 18th and 20th centuries, thanks to a few over-eager hunters (and by a few, I mean all of them).

Today, sperm whales are considered one of the most populous species of massive marine mammals; bowheads, on the other hand, are still in trouble, despite a 20% increase in population since the mid-1980s. Makes those few elderly bowheads that much more impressive, huh?

Unfortunately, just as things are looking up, these wonderful whales are in trouble once again.

We might not need to worry our real-life Captain Ahabs anymore, but our big aquatic buddies are still being threatened by industrialization — namely, from oil drilling in the Arctic and the Great Australian Bight.

In the off-chance that companies like Shell and BP manage not to spill millions of gallons of harmful crude oil into the water, the act of drilling alone is likely to maim or kill millions of animals, and the supposedly-safer sonic blasting will blow out their eardrums or worse.

This influx of industrialization also affects their migratory patterns — threatening not only the humans who depend on them, but also the entire marine ecosystem.

And I mean, c'mon — who would want to hurt this adorable face?

BOOP.

Whales might be large and long-living. But they still need our help to survive.

If you want another whale to make it to his two-hundred-and-eleventy-first birthday (which you should because I hear they throw great parties), then sign this petition to protect the waters from Big Oil and other industrial threats.

I guarantee Moby Dick will appreciate it.
