The Difference Between Mist, Fog, Smog, Haze And Vog

There are a lot of different names for that stuff that causes reduced visibility—and an agonizingly long commute—in the morning. Mist and fog are caused by water droplets in the air, and the only difference is how far you can see. Haze is the reflection of sunlight off air pollution, while smog is what happens when pollution causes low-lying ozone. And vog only happens when a nearby volcano is releasing sulfur dioxide into the air to react with what’s already there.


The Difference Between Occultism And Mysticism

Both practices involve the alleged ability of the human mind to reach out and experience that which is beyond our regularly experienced senses. Mysticism often exists within the context of organized, established religion, while the same religion condemns occultism. Occultism is an experience of conflict whereby the person practicing it is attempting to control something or learn something that they shouldn’t know, while those who practice mysticism are striving to exist in harmony and peace with the greater world.


Difference Between Schizophrenia And Split Personality Disorders

When schizophrenia is mentioned, it often goes along with ideas that a person’s hearing voices from their other personalities. The two disorders are completely different, though, with those suffering from schizophrenia prone to delusions, hallucinations, and difficulty in finishing complete thoughts and sentences. Dissociative identity disorder (DID) happens when more than one personality exists in the same person, usually without the person being aware of it. DID often begins when a child struggles to come to terms with some sort of trauma, while schizophrenia is thought (but not confirmed) to be a genetic disorder.


The Difference Between Being Anal-Retentive And Having OCD

We all know those people who need to have things just so. Their tendencies might be the target of jokes, but those with real obsessive-compulsive disorders can find that their need to have things just right or their need to repeat things over and over again can ruin their lives. When habits become time-consuming, cause a person mental or emotional distress because they can’t stop their thoughts, and when their compulsions—which they do in order to try to alleviate that distress—only make it worse, they’re not just being anal-retentive, and it’s no longer a cause for jokes.


The Different Kinds Of Darkness

Darkness is a funny thing, and we think we know what it really is … until we’re in a place that’s really, really dark. All kinds of things can impact darkness, from city lights to pollution to cloud cover. The Bortle Dark-Sky Scale allows observers to measure, on a scale from 1 to 9, just how dark their sky really is based on which stars you can see with the naked eye. Skies that are ranked at 1 are the darkest, with 9 being the skies with the most light pollution. Dark skies are vanishing so quickly, there are even groups started to preserve them.


How Science Discovered Different Types Of Blood

It’s fairly common knowledge that we have different blood types and that those blood types dictate what we need when it comes to a blood transfusion. The idea of different blood types was only confirmed in 1900 by Austrian Karl Landsteiner, although earlier doctors had their suspicions when human-to-human transfusions failed. Until then, the idea of giving blood transfusions was a complicated one, and it was even tried with animal blood, although it ended badly.


The Difference Between Hoarding And Collecting

Between 700,000 and 1.4 million people in the United States alone have issues with hoarding, and the difference between hoarding and collecting is largely how a person feels about their surroundings. Collectors are proud of their items and display them, while hoarders keep their possessions because they can’t bear to throw them away, even though they’re ashamed. They feel anxious whenever anyone asks them about getting rid of things and, unlike collectors, there’s often an element of disorganization to their stash.


The Difference Between A Real Smile And A Fake One

Admittedly, some people are better at pulling it off than others, but according to scientific research, there’s still a definite difference between a real smile and a fake one. It all has to do with the interaction of the muscles around the mouth and cheeks with the muscles in the eyes, and there’s only one unique combination of these muscle movements that results in a smile that means happiness or contentment. Other types of smiles—including the one that you give at a really bad joke—can mean anything from sadness and smugness to barely concealed annoyance.


The Difference Between Pigs, Hogs, And Wild Boars

Pigs, hogs, boars—they all wallow in mud, root around, and can destroy nearly any vegetation in their path. But what makes a pig a pig and not a boar or hog? Ultimately, there’s no cut-and-dried difference, because farmers, hunters, and regular folk all use these terms a little differently and interchangeably. However, “pig” usually refers to the barnyard variety, a wild boar is the kind that lives out in nature and is the ancestor of domestic pigs, and “hog” is used to describe larger pigs and boars.


The Difference Between Teenage Brains And Adult Brains

Teenagers can look like adults, dress like adults, and even act like adults at times; sometimes, it might be hard to tell the teenagers from adults (and other times it isn’t hard at all). But it’s also crucial to remember that their brains are wired completely differently. It’s long been known that at the end of the day, teenagers just don’t think like adults, and that’s because the different sections of their brains aren’t connected the way they will be once they’ve matured a little more. Most specifically, teenagers lack many of the nerve connections that tie the frontal lobe to the rest of the brain, limiting their ability to think ahead.
