This Illustrated Periodic Table Shows How We Regularly Interact With Each Element

The ability to name all of the elements on the periodic table from actinium to zinc is an impressive feat. Actually being able to explain how each element functions in the real world is a little more challenging. If you agree that learning the everyday relevance of all the Earth’s elements is just as important as memorizing their symbols, check out the chart above. This graphic, spotted by inhabitat, presents the information found in a traditional periodic table with pictographs and labels indicating where you might encounter each element in your life.

“The Periodic Table of Elements, in Pictures and Words” was created by Boeing software engineer Keith Enevoldsen. He frames the design as a tool for teaching students in elementary through high school, but it can also be used by adults looking to polish their rusty knowledge from chemistry class. The uses of some elements are widely known: Sodium, for instance, is paired with a picture of a salt shaker, while neon is illustrated with an illuminated advertising sign. Others, though, aren’t so obvious: Did you know that strontium is used in fireworks, or that boron can be found in sports equipment? What about scandium in bicycles, or tantalum in cell phones? There’s a helpful illustration accompanying each element found in nature.

Enevoldsen’s table can also be used to study other facts, like each element’s atomic number and material state (solid, liquid, or gas). The educational resource is available as a set of print-out flashcards and as a full-sized poster available on Amazon for $10.

Be honest: You’ve watched a YouTube video or two in an attempt to learn how to play a song on the guitar. Whether it was through tabs or simply copying whatever you saw on the screen, the fun always ends when friends start throwing out requests for songs you have no idea how to play. So how about you actually learn how to play guitar for real this time?

It’s now possible to learn guitar from home with the Ultimate Beginner to Expert Guitar Lessons Bundle, which is currently on sale for $29. Grab that Gibson, Fender, or whatever you have handy, and learn to strum rhythms from scratch.

The strumming course will teach you how to count beats and rests to turn your hands and fingers into the perfect accompaniment for your own voice or other musicians. Then, you can take things a step further and learn advanced jamming and soloing to riff anytime, anywhere. This course will teach you to improvise across various chords and progressions so you can jump into any jam with something original. You’ll also have the chance to dive deep into the major guitar genres of bluegrass, blues, and jazz. Lessons in jam etiquette, genre history, and how to read music will separate you from a novice player.

This bundle also includes courses in ear training so you can properly identify any relative note, interval, or pitch. That way, you can play along with any song when it comes on, or even understand how to modify it into the key you’d prefer. And when the time comes to perform, be prepared with skilled hammer-ons, pull-offs, slides, bends, trills, vibrato, and fret-tapping. Not only will you learn the basic foundations of guitar, you’ll ultimately be able to develop your own style with the help of these lessons.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
