The story behind the popular game of numbers

SUDOKU, FUN WITH NUMBERS 

When you open the puzzles page in a newspaper, have you ever wondered about those blank grids with a few scattered numbers? They're Sudoku puzzles - a global craze!

In this game, you fill in the grid with singular, unique numbers. That’s where the name comes from: su means number and doku means single. Though the name is Japanese, the puzzle was actually created by American architect Howard Garns in 1979. He called it Number Place, but it didn't gain much popularity in the US. Japanese publishers discovered it in the 1980s, renamed it Sudoku, and by 1984, it was a sensation in Japan. 

Twenty years later, Hong Kong judge Wayne Gould came across Sudoku during a visit to Tokyo. He introduced it to The Times in London in 2004, sparkling a worldwide craze. By 2005, newspapers across Europe, India, and beyond had embraced Sudoku, and the puzzle's popularity has only grown since. 

Sudoku is simple but addictive. A classic puzzle features a grid of 9 large boxes, each divided into a 3X3 grid. Your task is to fill in the empty cells so that:

1. Each horizontal row contains the numbers 1 to 9 without repetition. 

2. Each vertical column contains the numbers 1 to 9 without repetition. 

3. Each 3X3 box contains the numbers 1 to 9 without repetition. 

It's not about Math - just logic and patience. With practice, you'll get better at spotting patterns and solving puzzles step by step. 

The fun doesn't stop there! You can swap numbers for letters, symbols or pictures and still follow the same rules. Modern variants, like jigsaw Sudoku or the tricky killer Sudoku, make it more exciting. 

Remember, every Sudoku puzzle is a test of logic, persistence and problem-solving. Ready to give it a try?

WHY DO OLD BATTERIES LEAK?

Batteries generate electricity through chemical reactions that move electrons between terminals. In alkaline batteries, a gel called potassium hydroxide conducts electricity. Over time, as the battery works, hydrogen gas builds up inside the sealed casing, increasing pressure. This can create tiny cracks in the metal, causing potassium hydroxide to leak.

When exposed to air, it reacts with carbon dioxide, forming a crust of potassium carbonate, which is harmless. However, potassium hydroxide itself can irritate the skin. To safely dispose the leaking batteries, place them in a plastic bag and take them to a recycling center. Proper disposal prevents environmental harm and keeps everyone safe.

An Accidental Genius

A STICKY STORY OF POST-IT NOTES 

Ever wondered about everyday things that turned out to be accidental strokes of genius? Well, let’s dive into the quirky tale of Post-it Notes – those handy, sticky pals that found their way into our lives in the most unexpected way.

Once upon a time, in a 3M lab in 1968, a scientist named Dr. Spencer Silver was working on a super-strong adhesive that could be used in aircraft construction. But guess what? He didn’t quite get what he wanted. Instead, he accidentally created a not-so-sticky adhesive.

Fast forward to a few years later, another 3M employee named Art Fry was singing in his church choir. He got frustrated when his bookmarks kept falling out of his hymn book. That’s when the light bulb went off in his head. He remembered Dr. Silver’s not-so-sticky adhesive!

Art took some of that magic not-so-sticky stuff, applied it to paper, and just like that – the Post-it Note was born! They were perfect for sticking things together without leaving a mess behind. The accidental genius of Dr. Silver’s not-so-sticky glue turned out to be a game-changer.

These colourful squares soon found their way onto desks, notebooks and fridges all around the world. People loved them for leaving messages, jotting down quick ideas and making colourful reminders.

What makes Post-it Notes quirky and cool is that they started as a ‘whoops’ moment in a lab. It just goes to show that sometimes, the best discoveries happen when you’re not looking for them. Imagine a world without these sticky wonders – pretty dull, right?

So, the next time you’re jotting down notes on a Post-it, remember the accidental brilliance behind it. It’s a reminder that genius can pop up in the most unexpected places, turning a not-so-sticky situation into a colourful burst of creativity!

The best method for setting priorities

A-B-C-D-E

All successful people focus their time and energy on their work of highest value. Good performance is about the capacity to focus and concentrate on the job of top priority. Whenever you feel overwhelmed by too many things to do and too little time in which to do them, sit down, take a deep breath, and list all those tasks you need to accomplish.

The best method for setting priorities is the A-B-C-D-E Method.

“A” stands for “very important”, something you must do. It is going to decide your success or failure.

“B” stands for “important”, something you should do. This is not as important as your ‘A’ tasks.

“C” stands for things that are “nice to do”, but which are not as important as ‘A’ or ‘B’ tasks.

“D” stands for “delegate.” You can assign this task to someone else who can do the job instead of you.

“E” stands for “eliminate, whenever possible.” You should eliminate every single activity you possibly can, to free up your time.

When you use the A-B-C-D-E method, you can very easily sort out what is important and unimportant. This then will make us be focused on those items on your list that are most essential for you to do.

HOW LOUD IS A SUPERSONIC PLANE?

Supersonic planes, like the Concorde or modern supersonic jets, create a sonic boom while flying faster than the speed of sound (about 767 mph or 1,235 km/h). The sonic boom is a thunder-like noise resulting from shockwaves produced by the aircraft. The loudness of a supersonic plane depends on various factors, including altitude and distance from the flight path. At ground level, a sonic boom can reach around 120 decibels, similar to a thunderclap. However, advancements in aerodynamics aim to minimise these disturbances. Newer supersonic planes incorporate design features to lessen the intensity of sonic booms, considering environmental impact and comfort.
