Wherever you roam around the world, home is the only place where your heart finds the ultimate in serenity. But how much attention do you pay to the things around you at home? Well, your mind is more relaxed when you are at home. Therefore, you often miss out on interesting things that could leave you stumped if you pay attention to them. Check out these 5 things you see every day in your home that will make you scratch your head. Keep scrolling down to explore the answers and blow your mind!
1 Why do batteries lose charge even when not in use?
Another interesting thing that you see every day in your home but you probably wonder enough about is that the battery loses its charge even if you don’t take it out of the package. Battery life mainly depends on its size and type. However, regardless of their rating, type, or size, batteries eventually lose charge after a certain period of time if you don’t use them or even take them out of the package. But why does that happen?
Well, the reason why batteries lose weight lies in their structure. Inside each battery are electrodes, which are coiled, anodized metal strips. Over time, the structure of the positively charged electrodes (i.e. the anodes) wears out.
This corrosion occurs due to oxidation, that is, due to the reduction of electrons on the anodes, which is an irreversible process in most cases. This causes efficacy to decrease over time, eventually leaving the battery with no power at all, even if you’ve never used it before.
2 Why does the clock run clockwise?
We determine the motion and motion of many things by comparing their direction to the clockwise direction. And we all know that clockwise only works to the right, i.e. clockwise. But not many people know how the things you see every day in your home work. Likewise, it can leave you wondering why the clock does not move counterclockwise. The answer to this is hidden in the path of the sun in the sky.
When you’re in the northern hemisphere and facing the sun’s path in the sky, the sun advances in an arc clockwise from the east into the southern sky above and then to the west. And when you make a sundial (an ancient clock based on the sun), the shadow you cast also follows a clockwise path from west to north, then east, that is, in the opposite direction to the path of the sun.
Therefore, along the way, mechanical watchmakers also adopted the same phenomena of clockwise movement or right clockwise movement, that is, the direction of the sundial’s shadow in the northern hemisphere. But why the northern hemisphere and not the southern? Because nearly 90% of the world’s population lives in the northern hemisphere. It also accounts for about 68% of the total land area.
3 Why do mirrors flip horizontally and not vertically?
Not a day goes by when you don’t see yourself in the mirror. But you can still miss the nitty gritty about the things you see every day in your home. We all know that mirrors flip the reflections horizontally. But why do they do that? Furthermore, why don’t mirrors flip the reflections vertically? For example, if you see the reflection of the letter “b” in the mirror, it will become the letter “d”. Likewise, when you raise your right hand in front of a mirror, it will look like you raised your left hand. But why is the mirror not turned upside down, that is, the reflections are turned vertically?
The fact is that mirrors do not flip things left to right (i.e. on the x-axis) or upside down (i.e. on the y-axis); They flip it from front to back (i.e. on the z axis). For example, if you point your finger to your left in front of a mirror, your finger’s reflection will also point to your left. Likewise, if you point to the right, up, or down, the reflection will also point to your right, up, or down. But when you point your finger in the direction of the mirror, i.e. away from you, you will find the reflection pointing at you! In other words, mirrors allow you to look at the object as if it were looking behind your head, without turning your head.
4 Why do credit cards have an expiration date?
Credit cards are great! They allow you to shop on the go and pay later. While we all know that credit cards have an expiration date, not many understand why. Credit card renewal is essential from the point of view of keeping the card up to date. But your credit card expiration date has many uses beyond that. For starters, your card’s expiration date is a security checkpoint. When you make a purchase online, you will have to check the expiration date to complete the transaction. So even if someone has your credit card number, they can’t use it for purchases or at all if they don’t know your card’s expiration date.
Moreover, your credit card issuer equips the card with security features that keep your data safe and secure. They keep rolling out new security features from time to time. With your card renewal, you get a card with the latest security features. For example, older cards do not have EMV chips or contactless payment features, while newer cards have these features enabled.
Aside from the above, your credit card expiration also gives you an opportunity for your card issuer to remarket their latest offers and services to you. You can even get a limit booster deal, bonus points or a gift voucher with credit card renewal.
5 How do ceiling fans collect dust when they are in constant motion?
No matter how often you clean the fan, the fan seems to have a magnet that attracts a lot of dust to it. The reason why your fan gets so much dust even when it’s moving all the time is something you see every day in your home, but you might not know why.
We all know about static electricity. After all, who doesn’t remember rubbing balloons on their heads to make their hair stand upright? Apparently, this is why dust accumulates on the fan blades. When you turn on the fan, the blades move quickly in the air to flow through the air particles. Creates a static electric charge on the fan blades.
Moreover, the air in your home contains many tiny dust particles that are also charged with static electricity. Dust particles attract other charged dust particles as they move through the fan air. These dust particles are eventually attracted to the electrostatically charged edges of the fan blades. Most of the dirt particles collect on the edge of the fan blade where it has the most charge due to the constant friction of the air. This way you can get dust on your ceiling fans even when they are constantly moving.
