Since the invention of the light bulb, humanity has advanced far ahead. Today, technology is around us everywhere and plays an important role in all areas of life.
New devices and technologies appear every day, along with myths that often accompany them.
These are the most common misconceptions about the technology we use on a daily basis.
Myth 1: Updating the desktop makes your computer run faster.
Are you updating the desktop on your computer? Updating the desktop is one of the most common myths among Windows users.
We tend to refresh the desktop every time the computer starts to slow down. Even if we do not have any problems, we have a desire to right-click on an empty space and select the "update" option. This habit is passed from one user to another without any explanation. Some people think that the update frees up RAM and makes the computer perform better.
What does this function actually do? It just updates the icons on the desktop, and that's it.
Myth 2: You need a camera with a lot of megapixels to take a good photo.
The world of photography has expanded significantly over the past few years. On average, about 60 million photos are uploaded to Instagram daily, and about 600 million active users use the application per month.
Even though the technology we use to take photographs has advanced a lot, some myths are deeply ingrained in our heads. Millions of people spend money because they believe that the more megapixels in a camera, the better your photos will be.
Camera companies understand this and continue to exploit this misconception.
What is a megapixel? That's a million tiny dots in a photograph. The smaller the colored dots, the brighter the photo. The truth is that good photography depends entirely on the camera lens, lighting, composition, and other factors.
Myth 3: Never put metal objects in the microwave
Have you ever accidentally left a metal appliance inside the microwave and then got scared when you saw sparks inside?
It can be dangerous when you put metal objects inside the microwave, but what if you knew it wasn’t that bad?
Some metals can be safely placed in the microwave. Moreover, there are metal components inside the microwave itself. Experiments have shown that the type of metal and the shape of the object play a role here.
For example, spoons can usually be used safely, while forks can create sparks due to the negative charge that builds up in the tines. Sparks can cause a fire, depending on the rest of the components inside the microwave. Even if there is no fire, they can still damage the microwave and make it unsafe to use.
Myth 4: Long-term use of mobile phones can lead to brain cancer.
Mobile phones do emit radiation that is absorbed by human tissues. But it is worth clarifying that mobile phones emit non-ionizing electromagnetic radiation, that is, the same radiation that comes from microwaves.
Ever since the first mobile phone was created in 1973, there has been a widespread myth that radiation from mobile phones is associated with brain cancer.
However, the signals that mobile phones emit are non-ionizing electromagnetic radiation, not ionizing radiation, which is a big difference. High levels of ionizing radiation are known to increase the risk of cancer.
Many studies done on non-ionizing electromagnetic radiation from radars, microwave ovens and mobile phones have shown that there is no such connection. For cancer cells to form in the body, significant DNA damage must occur, which non-ionizing radiation cannot do.
Myth 5: Video games spoil children.
We are used to hearing about how harmful computer games are, but science is not convinced of that theory.
A study by the University of Glasgow, which looked at data over a 10-year period and in which 11, 000 children participated, found that watching TV and playing video games did not significantly affect behavior.
What's more, the study found that children who played video games for about an hour a day were happier and better fit than those who didn't. Experts have yet to conclude whether violent video games have an impact on children's behavior.
Myth 6: Incognito mode in Chrome browser hides your search results from everyone
While Chrome's incognito mode is known to not hide you from others, many people believe this myth.
Modern browsers allow users to take advantage of the enhanced privacy option through incognito mode.
Chrome is one of the most popular browsers, and many people still believe that incognito mode hides all activity from prying eyes. This is despite the fact that Google has made it clear in the description of what this means. Basically, incognito mode simply prevents cookies, temporary Internet files, and browser browsing history from being saved from those who have access to your computer.
Myth 7: If you charge your phone or laptop battery before you fully discharge it, it will lose its ability to fully charge.
This was once true, but battery technology has improved significantly since then. Most devices today use lithium-ion and lithium-polymer batteries, which eliminates the problem.
The myth that rechargeable batteries need to be fully discharged is not scientifically supported. This was the case when the devices used nickel-cadmium or nickel-metal hydride batteries.
Since then, well-known companies such as Apple and Samsung have started using lithium-ion and lithium-polymer batteries, which fixes the problem.
You can recharge the lithium polymer batteries at your convenience, without the need for a full discharge. Continuous discharge of the battery can degrade the performance of the devices over time.
It is worth remembering, however, that no matter how you use your smartphone battery, it retains its full capacity for about 2-3 years.
Myth 8: Magnets can completely erase data from hard drives and flash drives.
This statement was true when floppy disks were used in the world. Most memory cards are not susceptible to magnetic fields.
Flash drives or memory cards do not have anything magnetic inside, so exposure to the magnetic field will not erase or damage the data. The same goes for hard drives. The only way to erase data from the hard drive is to rewrite the new data.
Myth 9: The use of telephones on an aircraft interferes with navigation and interferes with the aircraft's communications system.
Immediately before takeoff or landing, flight attendants are often asked to put down electronic devices. Why is this happening and does it interfere with navigation and the communication system?
According to some pilots, mobile phones and avionics do not come into conflict. The request to set aside mobile phones is more to grab the attention of passengers and for personal safety, so that devices do not fly around the cabin during takeoff or landing.
However, when several tests were carried out using signals simulating mobile phones in a camera (but not in a real plane), it was found that in several cases the compass froze, some instruments had errors, and communication systems were unclear. Until research disproves this, it's worth sticking to the rules.
Myth 10: Mac products do not need antivirus because they are not susceptible to viruses.
Mac OS is considered to be more reliable than Windows operating systems, but if you are concerned about security, you might want to install an antivirus. Since Macs themselves are much smaller than Windows, malware is less likely to be made for them.
In addition, the Mac operating system is Unix-like with built-in security options. To make its devices even more invulnerable, Apple has included a number of security measures, which further complicates attempts to compromise security.
However, it should be noted that there have been cases when devices have become the subject of attacks by Trojans and hacker programs.
