$125 million for a Grade-school math error

Image: Aaron Lefler

Imagine losing a hugely expensive spacecraft due to a simple mix-up between English and metric measurements . That is exactly what happened to NASA in 1999 when a Mars orbiter designed by Lockheed Martin was lost in space.

The confusion caused a malfunction on the $125 million craft, resulting in the probe’s loss. Although it was unusual for Lockheed to use English measurements for a NASA design (since NASA had stipulated using metric measurements for many years), there were still several instances where the error should have been caught but wasn’t.

Toys ‘R’ Us blunder

If you think an action figure of a drug dealer isn’t the best idea for a toy store , you’re not alone. Yet, for some reason, Toys "R" Us decided otherwise in October 2014, possibly hoping to cash in on the massive success of the Breaking Bad TV series.

Unsurprisingly, the giant toy retailer was forced to pull from its shelves four collectible dolls based on characters from the AMC hit show, each doll featuring a detachable sack of cash and a bag of meth.

Apple Maps' rocky beginnings

When Apple decided to launch its own map application on iOS devices after a conflict with Google in 2012, users quickly realized that the Apple app was not nearly as launch-ready as it should have been .

Locations were mislabeled, roads were missing, and it occasionally steered people in entirely the wrong direction. The problem was eventually, though largely, resolved, but it was an embarrassing misstep for a company known for never launching a product before it was as near-perfect as possible.

Bank of America debit card fee

Image: Ali Mkumbwa

Back in 2011, when the backlash against the banking industry had not yet reached its boiling point, Bank of America announced it would charge customers $5 per month to use their debit cards .

It was a bad business decision. More than 300,000 people signed an online petition, and Fox Business Network’s Gerri Willis cut up her debit card on air. The bank pointed to federal regulations as the reason for the charge but ultimately capitulated to consumer demand after a month before the fees went into effect.

$33 airline tickets from Toronto to Cyprus

If buying a business class ticket regularly priced at $2,558 for just $33 sounds too good to be true, it probably is. Except in 2006, when an Alitalia employee accidentally forgot to input two extra zeros when pricing business-class tickets from Toronto to Cyprus.

Due to the exchange rate on that day and the blunder, hundreds of buyers managed to snag fares for just $33. The airline honored those deals, accepting the heavily discounted price for the 509 people who purchased tickets before the error was detected.

A $70 million comma

As the folks at NASA and Alitalia have shown us, small errors can lead to costly mistakes. The following blunder comes courtesy of Lockheed Martin , which issued a contract to a customer with a missing comma in the sale price .

The astute customer held the aerospace company to the contract, costing Lockheed Martin $70 million for a C-130J Hercules aircraft in June 1999.

Sears misses the ship

A retail giant that faced a situation similar to the one Kodak faced—embrace the new and unknown or cling to the old, successful recipe—Sears sold everything from socks to tires via mail order, shipping across the U.S.

Choosing to stick with the old method, the company ended its catalog and delivery business in 1993 . In 1994, Amazon was founded , filling the business void that Sears had just created. The rest is history.

Passing on Microsoft

Image: Jaime Marrero

$60 million might seem like a lot of money to us regular folks, but for someone with very deep pockets like Texas businessman and two-time U.S. presidential candidate Ross Perot, it wasn’t all that much.

In 1979, he was offered the chance to buy Microsoft for that sum. However, his final offer to the tech company was just $15 million, and as a result, the Texan missed out on the opportunity to own what would become one of the biggest companies in the world .

Blackberry sticks with the old

Image: Thai Nguyen

Another case of a brand sticking with the old instead of embracing the new, BlackBerry was all the rage at the start of the 21st century— until Steve Jobs came along with the Apple iPhone .

While BlackBerry Messenger was extremely popular, with over 80 million users worldwide, the device lacked the new touchscreen functionality and sleek design of the Apple product. From being a market leader, BlackBerry’s market share plummeted to 0.2% by 2016.

RadioShack’s downfall

Image: Jelleke Vanooteghem

Not so long ago, RadioShack was a familiar presence on the streets and the go-to place for buying batteries and electronics. But it was that same brick-and-mortar presence, coupled with a reluctance to embrace e-commerce , that ultimately led to its demise .

Eventually, poor profit margins on what they could sell, combined with a loan they couldn’t repay, brought down what was once the go-to place for electronics.

If you've ever imagined what hell might look like, Hawaii Volcanoes National Park could come close—not because it’s a place of suffering (you'll actually witness some of the most incredible views on Earth), but because it's full of glowing, molten, menacing lava. The lava flows from Kīlauea, one of the most active volcanoes in the world. But not everything here burns; this national park is also home to unique flora and fauna.

Grand Prismatic Spring, Wyoming

What you're looking at might resemble a weather forecast map, but it's not. It's the Grand Prismatic Spring, Yellowstone's most famous hot spring. With its brilliant blue, orange, yellow, and green hues, it looks like a surrealist painting. Although it might look small in pictures, the Grand Prismatic Spring is huge—about 370 feet in diameter and 160 feet deep. That makes it the largest hot spring in the US and the third largest in the world!

If you want to feel like you're walking through a giant red stone maze, Antelope Canyon near Page, in northern Arizona, is the perfect spot. Carved over thousands of years by flash floods and erosion, its towering walls allow sunlight to stream in from above, creating an unforgettable experience for visitors.

Painted Hills, Oregon

Image: Ashley Bard

If an artist were to paint a series of enormous hills in vibrant colors, it would probably look a lot like Oregon's stunning Painted Hills. Located within the John Day Fossil Beds National Monument, these hills display stripes of red, yellow, gold, and black. But that's not all! The colors shift with the seasons and change throughout the day, creating a breathtaking, ever-changing landscape.

Exploring caves can be risky and terrifying for many, but imagine a cave system made entirely of ice! It sounds like something from a fantasy movie, but it really exists—and it's in Alaska. The stunning Mendenhall Glacier Ice Caves lie beneath the glacier of the same name, formed by meltwater carving tunnels and chambers deep within the ice.

Turnip Rock, Michigan

Turnip Rock, located in the famous Lake Huron in Michigan, is as fascinating as it is mysterious. What makes this rock so special? Standing about 20 feet tall, it has a turnip-like shape—its narrow base supports a much wider top—giving it a perfectly balanced appearance that amazes all who see it.

The Mendenhall Glacier Ice Caves are just one of Alaska's many spectacular sights. Another must-see is the incredible Hubbard Glacier in southeastern Alaska, one of the largest and most active tidewater glaciers in North America. Trust us— its sheer size and dramatic ice cliffs will absolutely blow your mind!

Bisti/De-Na-Zin Wilderness, New Mexico

Image: Robert Harkness

When it comes to surreal landscapes, New Mexico's Bisti/De-Na-Zin Wilderness can't be left out. Its towering rock formations, blending shades of white, gray, red, and orange, were shaped by erosion and look like something straight out of another planet!

Mammoth Cave, Kentucky

A cave doesn't always have to be a small, cramped space. Mammoth Cave stands out with its enormous underground chambers, filled with impressive rock formations in both shape and size. In fact, it's the world's longest-known cave system—and it's right here in the state of Kentucky!

Oprah Winfrey

If it wasn't for a professor's advice, we might have never got to meet the incredible Oprah Winfrey!

After graduating with honors from high school, Oprah attended Tennessee State University to study Communication. During her college years, she already participated in several different radio shows. While in one of her classes, she received a call that changed her life: CBS Channel Five offered her a very important job. At first, Oprah said no, as her father always insisted that she complete her studies. Accepting the position would mean putting her education on hold, so it was a difficult choice for her.

Winfrey told the situation to her Scenic Design professor, who immediately encouraged her to take the job. "This is what you study for, to get a call from CBS!" he allegedly said.

Bill Gates

Bill Gates' work, intelligence, and journey as an entrepreneur to become the famous co-founder of Microsoft are admirable. Maybe that's why many are surprised to learn that Gates dropped out of college.

He began his education at a private school in Seattle, Washington. It's said that he demonstrated high capacities in math and science. During the early years of his education, he came into contact with computers, awakening his passion at a young age.

When he was 18 years old, Gates enrolled at Harvard to pursue a degree in computer science. During his time there, he became interested in programming languages. In particular, he wanted to design one for the Altair 8800, an early personal computer developed by MITS. In 1975, Gates decided to leave Harvard to create BASIC, which later evolved into the well-known Microsoft, co-founded by Gates and Paul Allen.

Steve Jobs

A similar path to Gates was that of Steve Jobs, the co-founder of Apple Inc.

Jobs attended elementary and high school in Cupertino, California. In the 1970s, while he was still in high school, he met Steve Wozniak, an engineering student who would join him in creating Apple.

Jobs was said to have a free and rebellious nature. Perhaps it was that spirit that led him to leave Reed College in Portland, Oregon, after the first semester in order to have more time to pursue his true interests: technology and design.

Although he didn't pursue what we know as a formal education, Jobs educated himself in numerous fields in different parts of the world.

Jobs and Gates aren't the only tech geniuses who decided to drop out of college to take another path. Mark Zuckerberg joins this list.

Zuckerberg already stood out during his elementary and high school years for his mathematics and computer science skills. But it was at Harvard University that he really explored his potential.

Mark Zuckerberg enrolled at Harvard in 2002 to study computer science and psychology. There, he developed a number of applications and platforms, but one gained him all the fame. We're talking about Facebook, one of the most famous social networks in the world today. Two years after entering the university, he left to fully dedicate himself to his company, which was growing in success every second.

Not all the names on this list belong to the tech world. There are also some other showbiz figures. One of them is Ellen DeGeneres, the unmistakable comedian, actress, and TV host who has won the hearts of many Americans.

Her comedy and acting talents shone during her high school years in Atlanta, Texas. After high school, Ellen enrolled at the University of New Orleans in 1976 to study communications. However, after a couple of months, she dropped out in order to concentrate on her entertainment career. During those years, she did comedy and stand-up shows, gaining fame first locally and then nationally, eventually having her first sitcom, "Ellen," and then her successful daytime talk show, "The Ellen DeGeneres Show."

Steven Spielberg is a talented and successful American film director whose name reached the ears of the whole world thanks to such classics as Jaws (1975), Raiders of the Lost Ark (1981), E.T. the Extra-Terrestrial (1982), Jurassic Park (1993), and many others.

In 1965, Spielberg enrolled at California State University Long Beach to pursue a career in film production. There, he started to work on many projects, and in 1968, he decided to drop out of college to pursue his passion.

In the 2000s, the famous director returned to college and completed his degree, presenting the iconic Schindler's List !

Brad Pitt

The art of acting is truly admirable, and we can say, without a doubt, that the best actors and actresses in the world have a great mix of natural talent and hard work. A perfect example is Brad Pitt, who also has one more ingredient: his spectacular appearance.

After graduating from high school in 1982, Pitt enrolled at the University of Missouri to study Journalism and Advertising. There, he became interested in acting and participated in different creative and theatrical projects.

Two weeks before graduating, Pitt made the decision to quit college and move to California, where he would evolve as an actor into the world-renowned superstar he is today.

Larry Page

Lansing, Michigan, was the birthplace of Larry Page, the co-founder of one of the world's largest technology companies. But before becoming the CEO of a huge corporation, Page also walked the halls of college, earning several degrees before his dropout.

Page earned a Bachelor of Science with a major in Computer Engineering with honors from the University of Michigan in 1995. He then enrolled at Stanford University, where he earned his Master's degree in 1998.

During his years at Stanford, he met Sergey Brin, with whom he would later co-found none other than Google! The success of their co-creation led Page to not complete his PhD, which he was pursuing during those years.

Ashton Kutcher

When it comes to talented, hard-working, and handsome actors, Brad Pitt isn't the only one. Another one with all those attributes is Ashton Kutcher.

Kutcher is really smart. His hard work and intelligence led him to enroll at the University of Iowa in 1996, where he pursued a degree in biochemical engineering. But his student life was cut short when a talent agency discovered him.

In 1998, he decided to drop out of college to pursue his growing modeling and acting career. A few years ago, the actor famously declared, "I pursued something I was passionate about [...] So, that was the right decision for me."

Another artist on this list is none other than Alicia Keys, a major name in the entertainment world.

From a very young age, Alicia was encouraged to pursue her talent and artistic interests. She attended elementary and high schools specialized in arts, where she developed many of her musical talents.

After graduating from high school at 16, Keys was accepted into the Juilliard School in Manhattan, which is proof of her immense talent.
