Times are changing and it seems as if the more we progress, the faster they change. The one thing that hasn’t changed is our need to communicate but the way we communicate has adjusted over the years.
Many of us can probably look back and remember the time when we were tethered to the wall when we wanted to talk to someone on the phone. We wrote letters and put them in the mail and if somebody wasn’t home, we couldn’t talk to them at that moment.
These days, we communicate by sending text messages or messages over social media. We have video calls and if we can get in touch with somebody, it quickly gets on our nerves.
There have also been a number of innovations over the years that were brilliant in their time but these days, they are not used very often. That is especially true in the day when we used to use the Postal Service to deliver letters and packages on a regular basis.
One of the most important things to consider when delivering a letter or package was the weight. It would make a difference in the shipping rate, and that is where this unique invention, the postal scale, comes into play.
Long before we were sending emails and text messages, we were delivering things through the Postal Service. Analog mechanisms that included balances and springs were used to determine how much we would pay in postage. It wasn’t an exact science, but it was close enough.
Postal scales still exist today but they are much more advanced. They are precise instruments that have advanced features and it makes it much less personal when it comes to getting service at the post office.
Aside from the fact that the older postal scales were not 100% accurate, the design and nostalgia are something to consider. These are more than an item that used to weigh the letters we sent, they are collector’s items and some enthusiasts will pay big money for them.
So if you ever see a vintage postal scale, stop to ponder over what it may have done in its lifetime. It’s an item we don’t use as much anymore, but it is an item from time that we should forget.
Why is that?
The Answer is:
If a vehicle drives in a straight line at high speed for a long time, it will cause the driver’s vision to become fatigued, attention to be distracted, and even lead to drowsiness, which is unsafe. Therefore, driving on a road that changes from straight to curved will stimulate the driver’s concentration better.
Not to mention, builders also consider that a powerful vehicle can easily climb a steep road, but a heavily loaded truck or a passenger vehicle cannot. Moreover, a road with a straight, steep incline is extremely dangerous when descending, as it is difficult to control speed. A steep incline can also affect the driver’s visibility, making it hard to see ahead.
When designing curves, builders try to increase the curve radius and reduce centrifugal force, allowing vehicles to handle the turn more easily even at high speeds.
In summary, while winding roads may take more time to travel, they ensure greater safety. Driving on a steep, straight road is akin to playing a dangerous game that most people wouldn’t want to try.
