Why Can You Only Travel With 3.4 Ounces of Liquids?

Because three ounces of explosives aren’t enough to critically damage a plane. The TSA’s 3.4-ounce limit may seem like an arbitrary pain in the neck, but there is science behind it. After the Feds foiled a liquid explosive plot in 2006, officials tested explosives and determined the amount of liquid needed for a serious blast. In fact, 3.4 ounces is the maximum amount of liquid that poses little to no risk to travelers. So while chugging a soda at the security checkpoint is nobody’s idea of fun, at least the TSA has a good reason for confiscating rogue beverages.

Oh, and since you were going to ask: Yes, you can carry a pie through a TSA checkpoint, but the agency’s website warns, “[P]lease be advised that they are subject to additional screening.”

It's difficult to think of a hobby or job that doesn’t involve some element of coding in its execution. Are you an Instagram enthusiast? Coding and algorithms are what bring your friends' posts to your feed. Can’t get enough Mental Floss? Coding brings the entire site to life on your desktop and mobile screens. Even sorting through playlists on Spotify uses coding. If you're tired of playing catch-up with all the latest coding techniques and principles, the 2020 Python Programming Certification Bundle is on sale for $49.99 to teach you to code, challenge your brain, and boost your resume to get your dream job.

Basically, coding is how people speak to computers (cue your sci-fi vision of a chat with a creepy, sentient computer), and while it does sound a bit futuristic, the truth is that people are talking to computers every day through a program called Python. The 2020 Python Programming Training Certification Bundle will teach you how to build web applications, database applications, and web visualizations in the world’s most popular programming language.

Python is also the language computers are using to communicate back to programmers. You’ll learn how Jupyter Notebook, NumPy, and pandas can enhance data analysis and data visualization techniques with Matplotlib.

Think back to your creepy, sci-fi visual from earlier; was it some form of artificial intelligence? Contrary to what you may have seen in the movies, artificial intelligence is something you can learn to create yourself. In the Keras Bootcamp, you’ll learn how to create artificial neural networks and deep-learning structures with Google’s powerful Deep Learning framework.

Coding is associated with endless text, numbers, and symbols, but the work code is performing is hardly limited to copy. Dig deep into image processing and computer vision tasks with sessions in OpenCV. You’ll give yourself an extra edge when you can use Python for sifting through information and implement machine learning algorithms on image classification.

Explore coding education with the bundle’s 12 courses, spanning from beginner to advanced levels, to elevate your skillset from home. The 2020 Python Programming Certification Bundle is on sale for $49.99.

The 10 Best Beaches in America, According to Dr. Beach

When searching for the perfect stretch of beach to laze away your vacation days, there are quite a few factors to consider. Some, like water clarity or sand texture, are more obvious than others; for example, you might not realize how much noise pollution a nearby highway generates until you’re already on the beach.

To help you choose your next seaside getaway, Florida International University coastal research professor Stephen P. Leatherman, also known as “Dr. Beach,” has released his annual list of the top 10 beaches in the U.S. Based on 50 criteria, ranging from the beach’s width at low tide to the presence of jellyfish, the data reveals the Florida Panhandle is home to the best beach in the country. Grayton Beach State Park boasts exceptionally fine, white sand known as “sugar sand”; shallow, warm water with calm waves; and a 2000-acre nature park with rare coastal dune lakes and a hiking trail. It wasn’t the only Florida beach to make the list—Caladesi Island State Park, off the coast of Dunedin and Clearwater, came in at number six.

North Carolina’s Outer Banks islands were well-represented, too, with Ocracoke Lifeguarded Beach and Buxton’s Lighthouse Beach taking the second and fifth spots, respectively. Dr. Beach also bestowed top honors on two of Hawaii’s beaches: Oahu’s Duke Kahanamoku Beach and the Big Island’s Hapuna Beach State Park.

Even if you can’t make it as far as Florida or Hawaii, Dr. Beach’s metrics can help you decide what’s important to you when it comes to choosing the best beach closer to home. Maybe you’re not bothered by online reviews that warn about giant waves at a certain beach, but you’re unwilling to budge about overcrowding.

The list of criteria isn’t the only way that Dr. Beach is helping beachgoers plan the best, safest summer vacation possible—he’s also compiled a few handy tips for heading to the beach during the coronavirus pandemic. First and foremost, you should check the beach’s rules before you go; some places are only open for exercise, while others have made masks mandatory (even if yours doesn’t require a mask, however, you should still wear one). Dr. Beach also recommends having a backup plan, just in case your ideal beach hits capacity before you get there.
