10 Crazy Paradoxes That Will Blow Your Mind

10 Crazy Paradoxes That Will Blow Your Mind

A paradox is a premise that contradicts itself. It’s a situation that seems to defy logic by producing an inconsistency that goes against common sense. Most logical paradoxes are known to be invalid arguments. However, they are still valuable for promoting critical thinking and sometimes proving a point by contradiction. Teasing your mind and question everything you think you know makes for great intellectual activity. Indeed, the closer you examine things, the more you’ll start to discover paradoxes all around you.

Here are some of the most fascinating paradoxes you should know about. These will boggle your mind every time you read or think about them. Enjoy!

1. Likely to exist means likely to be found, but where is everybody?

A mind-blowing paradox comes from the apparent contradiction that exists between the high probability of extraterrestrial civilizations being out there somewhere, and our lack of alien contact or evidence.

In a universe of infinite space, the odds of life existing on a planet other than Earth are pretty high. However, no confirmed signs of intelligence have been spotted outside Earth, either in our galaxy or in the more than 80 billion other galaxies of the observable universe.

Hence physicists Enrico Fermi’s famous question: “Where is everybody?”

2. Does an object that has all its components replaced remain the same object?

This is a classic paradox drawn from the ancient Greeks’ original Ship of Theseus Paradox. It was famously described by Plutarch to get at the contradictions of identity. It goes like this:

You have an old wooden ship. You remove a plank from the ship one at a time and replace it with a new plank. You do this with every piece until the old ship is completely replaced. Is it still the same ship? If you construct a new ship out of the old pieces you took off the first ship, which one is the original ship?

A newer version of this paradox that drives the contradictions of identity closer to home replaces the “ship” with the “brain”. If you somehow quickly replaced parts of your brain material with identical clones and made a separate brain with the old brain material, would that be you too? Would you still be you?

3. Time travel (if possible) would result in some extremely strange situations.

Consider the following version of the popular science fiction themed Bootstrap Paradox, involving time travel and bringing an object or information back in time:

A stranger appears out of nowhere and hands you a strange device. The stranger then runs away and you never see them again. You discover the device handed to you is a time machine. After holding it for a while, you get bored. Instead of getting rid of it, you figure: “Hey, why not give it to myself?” So you go back in time and give yourself the device hence starting the whole cycle again.

Where did the device come from?

4. Can you travel back in time and prevent yourself from being born?

Another famous example of a time travel paradox is the Grandfather Paradox. In this mind blowing scenario, someone travels back in time and kills their own grandfather to prevent their own birth.

Think about this: A girl goes back in time and kills her grandfather before he has a chance to meet her grandmother and sire her father. Since her grandfather is dead, the girl was never born.

If she were never born, how could she kill her grandfather?

5. Can an omnipotent being defy the laws of logic and be both omnipotent and not omnipotent?

This version of the Omnipotent Being Paradox arises from the simple but strange exclamation: “Let God Almighty create a stone, which he himself is not capable of lifting!”

Can God be omnipotent and not at the same time? How does free will even exist if God is omniscient?

These are just some of the many paradoxes that arise when you try to apply logic to definitions of God or an almighty being.

6. If destiny designed a master plan which defines everything that is to happen, isn’t it useless to go to a doctor, for example?

According to this Lazy-bones Paradox, if you are ill and it is your destiny to regain health, then you will regain your health whether you visit a doctor or not.

If it is your destiny not to regain health, then seeing a doctor can’t help you. This is a paradox that might arise if you reject the notion of an omnipotent God or a supreme being who’s in charge.

How would you question this premise or supposition?

7. A heterological word is a word that does not describe itself. Does “heterological” describe itself?

For example, “verb” is a heterological word since it is not a verb (as opposed to “noun,” which is itself a noun). Similarly, “long” is a heterological word since it is not a long word (as opposed to “short,” which is actually a short word). So then, is “heterological” a heterological word?

Advertising

This is one of many self-referential paradoxes that have kept mathematicians and logicians up at night.

If “heterological” were a word that didn’t describe itself, then it would describe itself. However, if it did describe itself, then it would not be a word that described itself.

8. If someone says “I always lie,” are they telling the truth? Or are they lying?

The great stoical logician Chrysippos came up with a paradox popularly known as the Liar Paradox. It tells of a Cretan who sails to Greece. Upon arriving, he is greeted by Greek men on the shore and says, “All Cretans are liars.” Did he speak the truth, or did he lie? A week later, the Cretan sails to Greece again and says, “All Cretans are liars and all I say is the truth.”

The Greeks were truly puzzled. None were more confused than the grammarian and critic Philetus of Cos, who is said to have died of exhaustion while attempting to resolve the paradox.

Maybe we should just let this one go unsolved then? No?

9. A barber shaves everyone who does not shave himself, but no one else. Who shaves the barber?

This paradox is similar to the Liar Paradox. It was formulated by English logician, mathematician, and philosopher Bertrand Russell to emphasize the importance of establishing careful rules when creating sets. His Set Theoretic Paradox would lay the groundwork for 20th-century mathematics.

It goes like this: There is only one barber in town. The barber (who is a man) shaves only those men who do not shave themselves, but no one else.

Who shaves the barber? Does he shave himself?

10. What happens when an unstoppable object faces an immovable object?

An ancient story is told of a man who was walking through a market when he came across a merchant. The merchant advertised two of his wares boldly: “This spear can pierce any shield!” and “This shield can block any spear!”

The man contemplates these opposing statements for a moment. He then walks up to the merchant and asks, “What happens when you pierce the shield with the spear?” The merchant had no answer to this question.

A more recent account of an unstoppable object facing an immovable object involves a bullet and armor. Imagine there is a bullet which can shoot through any barrier. There is also some absolutely bullet-proof armor which no object can penetrate.

What will happen if such a bullet hits such an armor?

How to Improve Memory and Boost Your Brainpower

How to Improve Memory and Boost Your Brainpower

Have you ever noticed that some people are able to effortlessly remember even the most mundane details and quickly comprehend new things? Well, you can too!

To unlock the full potential of your brain, you need to keep it active and acute. Wasting time on your couch watching mindless television shows or scrolling through facebook is not going to help.

Besides getting out flashcards, what can you do to help remember things better and learn new things more quickly? Check out these 10 effective ways on how to improve memory:

1. Exercise and Get Your Body Moving

Exercising doesn’t just exercise the body, it also helps to exercise your brain. Obesity and the myriad of diseases that eventually set in as a result of being overweight can cause serious harm to the brain.

Furthermore, without regular exercise, plaque starts to build up in your arteries, and your blood vessels begin to lose the ability to effectively pump blood. Plaque buildup leads to heart attacks and it also reduces the amount of oxygen and nutrients that your blood carries to your brain. When the nutrients don’t make it there, the brain’s ability to function is compromised.

To prevent this from happening, make sure you get moving every day. Even if it’s just a brisk walk, it’ll help you maintain and increase your mental acuity. Brisk walking, swimming and dancing are all excellent activities. Take a look at these 5 Ways to Find Time for Exercise.

2. Eliminate Stressors and Seek Help If You’re Depressed

Anything that causes you major stress, like anger or anxiety, will in time begin to eat away the parts of your brain that are responsible for memory. Amongst the most brain-damaging stressors is depression, which is actually often misdiagnosed a a memory problem since one of its primary symptoms is the inability to concentrate.

If you can’t concentrate, then you might feel like you are constantly forgetting things. Depression increases the levels of cortisol in your bloodstream which elevates the cortisol levels in the brain. Doctors have found that increased cortisol diminishes certain areas of the brain, especially the hippocampus which is where short-term memories are stored.

Prolonged depression can thus destroy your brain’s ability to remember anything new. Seek professional help to combat your depression – your brain will thank you.

3. Get a Good Night’s Sleep and Take Naps

Getting a consistent 7 to 8 hours of sleep each night will increase your memory. During sleep, the brain firms up memories of recently acquired information.

Getting enough sleep will help you get through the full spectrum of nocturnal cycles that are essential to optimal brain and body functioning during the waking hours. Taking a nap throughout the day, especially after learning something new, can also help you to retain those memories as well as recharge your brain and keep it sharper longer.

4. Feed Your Brain

Fifty to sixty percent of the brain’s overall weight is pure fat, which is used to insulate its billions of nerve cells. The better insulated a cell is, the faster it can send messages and the quicker you will be thinking.

This is precisely why parents are advised to feed their young children whole milk and to restrict dieting – their brains’ need fat to grow and work properly. Skimping on fats can be devastating even to the adult brain.

Thus, eating foods that contain a healthy mix of fats is vital for long-term memory. Some excellent food choices include fish (especially anchovies, mackerel and wild salmon) and dark leafy green vegetables. Here’re more brain food choices: 12 Foods that Can Improve Your Brain Power

Deep-fried foods obviously contain fat but their lack of nutritional value is not going to help your brain or your body, so think healthy foods and fats.

5. Eat Breakfast and Make Sure It Includes an Egg

According to Larry McCleary, M.D., author of  The Brain Trust Program, an egg is the ideal breakfast. Eggs contain B vitamins which help nerve cells to burn glucose, antioxidants that protect neurons against damage; and omega-3 fatty acids that keep nerve cells firing at optimal speed.

Other foods to add to your breakfast include fruits, veggies and lean proteins. Avoid trans fats and high fructose corn syrup. Trans fats diminish the brain cells’ ability to communicate with each other and HFCS can actually shrink the brain by damaging cells.

Having a healthy breakfast in the morning has been shown to improve performance throughout the day. If you’re too busy to have a healthy breakfast, this maybe just right for you: 33 Quick And Healthy Breakfasts For Busy Mornings

6. Write it Down

If there’s something you want to remember, writing it down can help.

It may sound like a no-brainer, but do you really know why? Writing it down creates oxygenated blood flow to areas of your brain that a responsible for your memories and literally exercises those parts of it. Here’s How Writing Things Down Can Change Your Life.

You can start a journal, write yourself emails or even start keeping a blog – all of these activities will help to improve your capacity to remember and memorize information.

7. Listen to Music

Research shows that certain types of music are very helpful in recalling memories. Information that is learned while listening to a particular song or collection can often be recalled by thinking of the song or “playing” it mentally. Songs and music can serve as cues for pulling up particular memories.

8. Visual Concepts

In order to remember things, many people need to visualize the information they are studying.

Pay attention to photographers, charts and other graphics that might appear in your textbook; or if you’re not studying a book, try to pull up a mental image of what it is you are trying to remember. It might also help to draw your own charts or figures, or utilize colors and highlighters to group related ideas in your notes.

9. Teach Someone Else

Reading material out loud has been shown to significantly improve memory of the material. Expanding further upon this idea is the fact that psychologists and educators have found that by having students teach new concepts to others, it helps to enhance understanding and recall.

Teach new concepts and information to a friend or study partner, and you’ll find you remember the information a lot better.

10. Do Crossword Puzzles, Read or Play Cards

Studies have shown that doing crossword puzzles, read or play cards on a daily basis not only keep your brain active but also help to delay memory loss, especially in those who develop dementia.

So pick up the daily newspaper and work on that crossword puzzle, read a book or enjoy a game of solitaire.

Pick one to two of these tips first and start applying them to your everyday life. Very soon you’ll find yourself having better memories and a clearer head!
