Humanity has always had the Moon as a companion, using it to track time and the seasons and even believing it capable of affecting people’s behavior. As Earth’s only natural satellite, the Moon has a significant influence on our planet, from causing tides to keeping the globe from tilting even more. Let’s learn more about her!

No one is certain about how the Moon came to be, but scientists have some educated guesses. The most widely accepted hypothesis is that the Moon is a by-product of a collision between a very young planet Earth and another celestial body the size of Mars. This collision not only left Earth permanently tilted, but it also blasted large amounts of material into space. The Moon is thought to have formed from this debris and, in consequence, is related to Earth.

Similar to Earth, the Moon also experiences ‘earthquakes’ or, in this case, moonquakes. But, unlike Earth, the Moon lacks tectonic plates. Instead, its seismic activity is caused by meteorite impacts, the gravitational pull of the Earth and the Sun, and shrinkage due to heating and cooling. These quakes are nowhere near as strong as an earthquake, but they are significant enough to pose challenges for the construction of permanent lunar bases.

One side of the Moon is always obscured, but this doesn’t mean it is perpetually dark. Each face of the moon experiences about two weeks of sunlight at a time, while the other side experiences night. However, one of its sides is constantly facing away from the Earth, which means there is a side that we don’t see. It has been called ‘the far side’ and ‘the dark side’, not because it lacks light, but because it is unknown.

We always see the same face of the Moon from Earth, but its appearance changes depending on our location. It’s largely a matter of perspective: from the Northern hemisphere, the Moon is perceived "upright", while in the Southern hemisphere it appears effectively "upside down." A waxing crescent moon looks like a "D" in the North, but like a "C" in the South, with the light on the left. This explains why Northern hemisphere cultures have traditionally seen a man or rabbit in the Moon, while Southern hemisphere cultures haven’t. The markings on the Moon are the same, but they are perceived differently.

American astronauts and Soviet spacecraft landers have left several flags and banners on the Moon, but they are merely symbolic. According to the 1967 Outer Space Treaty, outer space and its celestial bodies—the Moon included—belong to mankind as a whole, and can’t be legally claimed by a single nation or owned as private property. The same treaty states that the Moon can only be used for peaceful purposes, prohibiting military installations and nuclear weapons. In recent years, however, the U.S. and other countries have challenged the Outer Space Treaty.

The Moon has its own gravity, weaker than Earth’s because of the size difference, yet it still exerts a significant influence on our planet. The Moon’s gravitational pull helps stabilize Earth’s axial tilt, preventing it from shifting constantly. This pull is the reason tides exist: water is a fluid, so it moves much more easily than land when pulled by the Moon’s gravitational force, creating the familiar rise and fall of the oceans.

Did you know that only twelve people have ever walked on the Moon? Neil Armstrong and Buzz Aldrin were the first to do so, on July 20, 1969, and the last was Gene Cernan on December 14, 1972. All twelve moonwalkers were American astronauts from NASA’s Apollo program. In total, six Apollo missions successfully landed astronauts on the Moon.

Unlike solar eclipses, the Moon is not completely darkened during a lunar eclipse. It is illuminated by the refraction of sunlight on Earth. As the light passes through the Earth’s atmosphere, it scatters, causing the light and the Moon to be perceived as reddish or as a ‘Blood Moon.’

Solar calendars are widely used today, but this wasn’t always the case. The lunar cycle and the phases of the Moon have been used to track time for thousands of years, and they are the origin of the idea of months and weeks. Although most of the world now officially uses the Gregorian solar calendar, the continued importance of lunar calendars can be seen in observances such as the Lunar New Year in many Asian cultures, the calculation of Easter in Christianity, Ramadan in the Islamic world, and festivals such as Holi and Diwali in Hindu traditions.

Werewolves, witches, lunatics. What does the Moon have to do with them? Cultures all around the world have, at some point, believed that the Moon had a powerful influence on human behavior, much as it does on Earth itself. Full moons in particular were thought to cause sleep deprivation and worsen mental conditions. Individuals who were ‘moonstruck’ were dubbed ‘lunatics,’ after luna, the Latin word for the Moon.

Not everyone is a car buff

10 car-related words to avoid getting fooled by the mechanic

As long as you aren’t directly involved in it, not being savvy with a certain profession’s lingo is usually not a problem. But alas, exceptions exist, and these situations can create confusion and anxiety for the uninformed party in a conversation. Just like a patient who struggles to understand the complex terms a doctor uses to explain their condition, many people feel unsure when a mechanic explains a problem with their car. Listed below are 10 words and phrases that car buffs and mechanics use frequently. How many of these do you know?

In the context of cars, the term "banger" refers to traditional combustion engines. While many people are familiar with engine cylinders, not everyone knows how the term "banger" relates to them.

For example, some refer to four-cylinder engines as "four-bangers" because of the distinct "banging" sound they produce.

When talking about pillars in a car context, we are referring to the structural divisions between the windows. The A-pillar typically denotes the section on each side of the windshield, the B-pillars are located between the driver and passenger windows, and the C-pillar is positioned toward the rear of the vehicle.

A limited-slip differential reduces wheel slip with the least traction, by shifting a portion of the torque to the wheel with the most traction, therefore, improving the performance of a car. This results in better overall traction.

Brake bias refers to how braking power is distributed between the front and rear wheels. Brake bias can either reference the front of the car or the rear, depending on where it’s dispersed. Brake bias is often expressed as a percentage of braking power sent to the front brakes (e.g., 52%).

The camber is an adjustable element of the car’s wheels that sets the tilt angle. Depending on the direction of the tilt, camber is classified as either negative or positive. Each car’s camber setting is adjustable and varies based on the driver’s preference.

How a driver sets their camber affects how quickly the tires wear over time. When in doubt, always check with a specialist.

Another expression relating to the brakes is the action of "bedding the brake pads." All brake pads require a bedding process to enhance performance, which involves creating a thin transfer film between the pads and the rotor.

A diagnostic check takes place when a mechanic connects a laptop or specialized equipment to a car to detect documented faults. Each fault is assigned a unique code, and by accessing the car's electronic control unit (ECU), the specific number will identify what the problem is.

Most modern mechanics use computers that can connect to a car’s electronic system and read the error log for problems.

In the automotive world, suspension bushings are small rubber components attached to suspension parts that help absorb shocks and vibrations from the road. Since they are made of rubber, they can deteriorate and wear out over time, requiring periodic replacement.

The third and final brake-related term on this list, "spongy brakes," is an expression used to describe an instance where the brake pedal offers little resistance when pressed down. This typically indicates a lack of brake fluid, which is fairly cheap to buy and add.

A car differential is a set of gears that splits engine torque, allowing the wheels to rotate at different speeds. This is especially important when turning, as the outer wheels must rotate faster than the inner wheels to cover more ground in the same amount of time.

The front differential is located between the two front wheels and distributes the engine’s power to the front wheels. In the same manner, the rear differential is located between the two rear wheels and distributes the engine’s power to the rear wheels.
