A teacher's viral extra credit questions lure students into a phenomenal prank

A mystery teacher has become an internet scholar after imgur user SharkyTheSharkDog shared photos of the extra credit questions on their exams.

While the first six are really fun—you should see if you can get them all correct—the last one is pure torture in the form of public humiliation.

6. Including "The Revenant," how many times has Leo DiCaprio been nominated for an Academy Award?

First person to read this, stand up proudly on your chair, and yell at the top of your lungs, "Oh Captain, My Captain!" will receive a 95% on this exam.

MIT’s trillion-frames-per-second camera can capture light as it travels

"There's nothing in the universe that looks fast to this camera."

Photographing the path of light.

A new camera developed at MIT can photograph a trillion frames per second.

Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.

The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds.

The amazing camera.

For some perspective, according to New York Times writer, John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."

In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water.

It's impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, "There's nothing in the universe that looks fast to this camera."

What will Earth look like if all its land ice melts? Here's your answer.

Climate change isn't pretty.

A map of the United States post land-ice melt.

Land ice: We got a lot of it.

Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice.

But what if it was all just ... gone? Not like gone gone, but melted?

If all of earth's land ice melted, it would be nothing short of disastrous.

And that's putting it lightly.

This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great.

Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

A comic about wearing makeup goes from truthful to weird in 4 panels.

A hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

A comic shows the evolution or devolution from with makeup to without.

Even though I don't wear very much makeup, every few days or so SOMEONE...

(friends, family, internet strangers)

...will weigh in on why I "don't need makeup."

Now, I realize this is meant as a compliment, but this comic offers a hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

“Why do you wear so much makeup?"

Not everyone is able to turn into a badass lizard when someone asks about their face-painting hobbies. Don't you kinda wish you could? Just to drive this hilarious comic all the way home, here are four reasons why some women* wear makeup:

*Important side note: Anyone can wear makeup. Not just women. True story.

Four reasons some women* wear makeup:

1. Her cat-eye game is on point.

3. Pink lipstick.

Yes, pink lipstick.

4. She likes wearing makeup.

Happy Going Out GIF by Much.

While some people may think putting on makeup is a chore, it can be really fun! For some, makeup is an outlet for creativity and self-expression. For others, it's just a way to feel good about themselves and/or enhance their favorite features.

That's why it feels kinda icky when someone says something along the lines of "You don't need so much makeup!" Now, it's arguable that no one "needs" makeup, but everyone deserves to feel good about the way they look.

Adorable 'Haka baby' dance offers a sweet window into Maori culture

Stop what you're doing and let this awesomeness wash over you.

If you've never seen a Maori haka performed, you're missing out.

The Maori are the indigenous peoples of New Zealand, and their language and customs are an integral part of the island nation. One of the most recognizable Maori traditions outside of New Zealand is the haka, a ceremonial dance or challenge usually performed in a group. The haka represents the pride, strength, and unity of a tribe and is characterized by foot-stamping, body slapping, tongue protrusions, and rhythmic chanting.

Haka is performed at weddings as a sign of reverence and respect for the bride and groom and are also frequently seen before sports competitions, such as rugby matches.

The intensity of the haka is the point. It is meant to be a show of strength and elicit a strong response—which makes seeing a tiny toddler learning to do it all the more adorable.

Here's an example of a rugby haka:

Danny Heke, who goes by @focuswithdan on TikTok, shared a video of a baby learning haka and omigosh it is seriously the most adorable thing. When you see most haka, the dancers aren't smiling—their faces are fierce—so this wee one starting off with an infectious grin is just too much. You can see that he's already getting the moves down, facial expressions and all, though.

@focuswithdan When you grow up learning haka! #haka #teachthemyoung #maori #māori #focuswithdan #fyp #foryou #kapahaka ♬ original sound - 𝕱𝖔𝖈𝖚𝖘𝖂𝖎𝖙𝖍𝕯𝖆𝖓

As cute as this video is, it's part of a larger effort by Heke to use his TikTok channel to share and promote Maori culture. His videos cover everything from the Te Reo Maori language to traditional practices to issues of prejudice Maori people face.

Here he briefly goes over the different body parts that make up haka:

This video explains the purerehua, or bullroarer, which is a Maori instrument that is sometimes used to call rains during a drought.

This one shares a demonstration and explanation of the taiaha, a traditional Maori weapon.

For another taste of haka, check out this video from a school graduation:

Heke even has some fun with the trolls and racists in the comments who try to tell him his culture is dead (what?).

@focuswithdan Credit to you all my AMAZING FOLLOWERS! #focuswithdan #maori #māori #followers #fyp #trolls ♬ original sound - sounds for slomo_bro!

Unfortunately, it's not just ignorant commenters who spew racist bile. A radio interview clip that aired recently called Maori people "genetically predisposed to crime, alcohol, and underperformance," among other terrible things. (The host, a former mayor of Auckland, has been let go for going along with and contributing to the caller's racist narrative.)

@focuswithdan #newzealand radio in 2021 delivering racist commentaries 🤦🏽‍♂️ #māori #maori #focuswithdan #racism DC: @call.me.lettie2.0 ♬ original sound - luna the unicow

That clip highlights why what Heke is sharing is so important. The whole world is enriched when Indigenous people like the Maori have their voices heard and their culture celebrated. The more we learn from each other and our diverse ways of life, the more enjoyable life on Earth will be and the better we'll get at collaborating to confront the challenges we all share.
