The World’s Most Dangerous Creature and a Life-Changing Invention

What Is the World’s Most Dangerous Creature?

One of the most dangerous creatures in the world is the box jellyfish. It lives mostly in the Pacific Ocean, but luckily, it’s not found near Israel. Its venom is 500 times stronger than that of a king cobra. A sting can be deadly or cause serious burns that don’t heal easily. Unlike many jellyfish that just float along with the water, the box jellyfish can actually swim to where it wants to go.

What Is an Elevator Pitch?

Imagine you're trying to sell a product or service. You get into an elevator with someone who might be interested. You have about 30 seconds to 2 minutes, the time it takes to ride the elevator and to explain what you're offering. What would you say?

That quick, focused explanation is called an "elevator pitch." It highlights the most important points in a short, clear way so the listener understands the value right away. Marketers work hard to craft pitches that are short but powerful enough to catch someone’s attention.

Who Invented the Calculator?

In the 1600s, Blaise Pascal built a machine that could do simple math like adding, subtracting, multiplying, and dividing. Later, in the 1800s, William Seward Burroughs created better machines that were faster and more accurate. These early calculators used a system of tiny gears to work.

In 1957, Casio released the first electronic calculator. It cost about $5,000 at the time! Over the years, calculators became smaller, easier to use, and much more affordable.
