Humanity has developed many ways to navigate itself throughout history. One of the most ingenious inventions to make this possible is the compass. In the early 1900s, a typical compass would be made out of some kind of metal, with a needle suspended in the middle. The designs of these “gadgets” would usually be quite simple.
But they did their job in showing the user north, south, east, and west. These days, compasses aren’t necessarily made out of metal. They can be found on laptops, smartphones, and other digital devices. As for manual compasses, liquid-filled versions became a popular substitute to the more traditional metal ones.
Truth be told, weighing scales were very different back in the early 1900s. For a start, they weren't so easy to come by. Unlike today, where most people have a relatively small, digital scale in their homes that they can use whenever they want, you would often need to use a public one in gym or a healthcare facility, as they were quite expensive to purchase back then.
What's more is that they were usually mechanical in nature, which meant that they weren't always as accurate as they are today. Digital scales of today are much more precise. Also, many modern scales provide a wide range of features and capabilities, such as the ability to calculate muscle mass, fat, and even bone density. They can even be connected to your smartphone.
Like many vehicles and modes of transport of yesteryear, early bicycles weren't necessarily the safest things to use to get from one place to the other. Both their suspension and brake systems weren't the sturdiest. In fact, early bikes had fork designs and frames that were pretty rigid. This meant that resistance to bumpy roads and rough surfaces was virtually nonexistent.
Nowadays though, bikes have the most advanced suspension systems. And you can look no further than mountain bikes, which are designed to allow riders to work their way through difficult terrain. Not to mention the fact that many early bikes didn't even have gear systems. That has definitely changed.
While versions of guitars have been played for thousands of years, we often associate this instrument with that modern "hourglass" design. In the early 1900s, and even before, guitars were built from traditional materials such as wood. And usually, they would be handcrafted. But nowadays, the exact same guitars can be produced by machines.
The electric guitar also rose in popularity during the rise of music genres such as pop, rock, heavy metal, and more. Generally, guitars of today are designed with an emphasis on optimized performance and comfort. But in theory, one could play the exact same tune on a modern guitar or one from the early 1900s.
While they might very much look the same as they did back in the early 1900s, soap has been through all kinds of changes since then. Originally, these items that we used to wash ourselves were predominantly made from vegetable oils or animal fats. These days though, soap can be made from other materials such as synthetic detergents.
Usually, the soap of yesteryear was handmade. But nowadays, soap can be produced en masse in industrial plants. The variety of aromas and scents of soaps is more varied now than ever before. Not to mention that soap can now come as foam, cream, and in other forms - not just as a bar.
