10 Inventions That Changed The World Around Us

It actually started when the first ape took a stick. Then there was the wheel, the printing press, the steam engine, electricity, and here you are in the digital world. You can easily read about all these inventions in any school history textbook, but Bright Side has made a list of inventions that we always take for granted when, in fact, they really changed the world. There’s a special bonus for the ladies at the end.
1. Barcodes


These little strips of boring black-and-white lines actually changed the way we shop. Though it normally says nothing to a regular customer, a barcode is of the utmost importance and can be found on almost every single item in a grocery store. Mic’s Chilli and its Hot Wings Sauce is an example of how some companies get more creative and use barcodes to improve the design of their package.
2. Pacemaker


This small but very important medical device maintains an adequate heart rate when a natural pacemaker doesn’t work properly. The latest models are roughly the size and shape of a pill and can be inserted via a leg catheter rather than invasive surgery.

3. Mauveine


Mauveine, also known as aniline purple, was accidentally invented by a student who tried to synthesize quinine. Instead, he got the first synthetic organic chemical dye, and many thousands have been prepared since then. But mauveine was the one that started a revolution in the world of fabrics and fashion.
4. Teflon


The invention of the material that we normally call Teflon was not just another important scientific discovery — it changed our attitude toward cooking. Nonstick frying pans with a Teflon coating can now be found in every kitchen.

5. Plumbing

Before indoor plumbing was introduced, sanitary conditions were far from satisfactory. In medieval castles, the toilet was just a tiny room with a hole in the floor, and all the waste just dropped below/outside the castle walls. The smell around the castle was quite a stench. Plumbing infrastructure really took public health and hygiene to a whole new level.

6. Vulcanized rubber

The modern process of vulcanization was not developed until the 19th century, mainly by Charles Goodyear. Today a vast array of products are made with vulcanized rubber, including shoe soles, hoses, and conveyor belts, although tires are the main product. Hard vulcanized rubber is used to make items such as clarinet and saxophone mouthpieces, bowling balls, and hockey pucks.
7. Safety glass

Safety glass is a common name for several types of glass. Toughened and laminated glass are often used in vehicle windows and windshields or interior design elements, while wire mesh is more often used in construction. It is hard to imagine our life without these wonderful inventions.

8. Concrete

Almost 2,000 years after it was built, the Pantheon’s dome in Rome is still the world’s largest unreinforced concrete dome. The first concrete-like structures were built in the Middle East region thousands of years ago. As the ingredients and combinations improved, concrete became one of the most widely used man-made materials.
9. Velcro

Velcro is actually a generic trademark for all the hook-and-loop fasteners we use. They consist of 2 fabric strips with tiny hooks (in the photo) on one and even smaller and “hairier” loops on the other. These touch fasteners became highly appreciated by everyone, from regular customers with young children to NASA specialists widely implementing them in spacecraft.

10. Stainless steel

It is believed that stainless steel soap can efficiently neutralize or reduce strong odors such as those from handling garlic, salami, or fish. Though scientific evidence of its efficacy as a soap appears lacking, its corrosion-resistant properties make stainless steel a widespread material in all spheres from cooking to construction.
Bonus

No more crouching over an unsanitary public toilet! This device is made of medical grade silicone and allows girls to urinate while standing up. Neat, discreet, and hygienic. This is what feminist victory looks like nowadays.
