How to improve your memory

HOW TO IMPROVE YOUR MEMORY

A strong and great memory is function of good health and vitality. Are you a student studying for exams? A working class interested in doing all you can to stay mentally alert? Or a senior and aged officer that longs to preserve and enhance his/her grey matter . In this post am going to be sharing with you somethings you can do to improve your memory and mental performance.
   Working with youngsters; I have been asked series of questions part taking to the improvement of memory. Questions like;
How can I Improve my memory?
How can I development a super memory?
How can I development a magnetic memory?

While from the adult folks;
How can I retain my super memory as I age? How can I Prevent Alzheimer as I age? These and many more questions have been asked.

The human brain has an amazing ability to adapt to changes even at old age. This ability is called neuroplasticity. When the brain is stimulated rightly, the brain form new neural pathways, affecting the already existing connections, reacting and adapting to ever change ways. You can use this natural Power of the brain (neuroplasticity) to increase your cognitive abilities, enhance your ability to learn new information and improve your memory at any age .The amazing ability of the brain is directly involved with the hippocampus. The hippocampus is crucial to information processing, acquisition of new memories, and retrieval of old memories. Below are some tips that will help you improve the functionality of your brain at any age.




Exercise Your Brain:  Like your muscles, your brain needs a regular workout to stay healthy and fit as you age. Without regular brain exercise (workout) your brain begins to lose it functionality. The more you workout your brain better you it processes and retrive  information . Not all brain exercise are equal in magnitude. The best brain exercise causes you to change your regular routine and cause you to develop new brain pathways. Lack of brain exercise will cause your brain to atrophy. Any brain exercise you decide to undergo must possess the following property * it must teach you something new *it must be challenging or tasky *it must be something that you can build on I.e develop.




PHYSICAL EXERCISE






     Physical exercise is very crucial to the health of the brain. Physical exercise increases the amount of oxygen and blood that reaches the brain cells and reduces the risk of  brain disorder that leads to memory lose, such as cardiovascular disease and diabetes. It also enhance the effects of brain chemical and reduces stress hormone e.g cortisol. Exercise plays an important role in neuroplasticity by boosting growth and stimulating new neural connections. 
When considering Physical that is beneficial to the memory, you should consider aerobic (cardio) exercise such as spinning, running, swimming, walking, hiking, kickboxing  e.t.c. These exercises generally keep the blood pumping.
Note, anything that is good for your heart is as well good for your brain. Any  workout that requires hand-eye coordination or a complex motor skills are essential for brain building.
Try To Splits  one’s Side At Least 20 times  Daily:
Did you know that when you laugh, the stress hormone cortisol decrease and thereby improving your short term memory.” According to a team of researchers from Loma Linda University in California, conducted a study on twenty healthy and normal older adults and found that those who watched a 20- minute distraction free funny videos scored better on a short term memory test than those who just wait calmly and did not watch any video. The control group had saliva samples analysed for the stress hormone, cortisol. The research found that those who laughed for 20-minutes lowered their blood pressure and decrease their level of cortisol which connected to stress”.
No wonder this adage stood the test of time “ laughter is the best medicine”. Laughter engages multiple regions across the brain while other emotional responses only engage a specific region. According to a renowned psychologist Daniel Goleman in one of his works note that “laughter seems to help people to think more broadly and associate more freely”. You might be asking yourself at this juncture that how can I make myself to laugh? I will like to suggest the following;
*Laugh at yourself by sharing your embarrassing moment with others
*Spend sometime with fun and playful people
*When you hear laughter move towards it’s
*Emulate little children
*Listen to jokes and comedy shows. 
STOP MULTITASKING: 

The age long used to describe the parallel processing abilities of computers, multitasking is now shorthand for human attempt to do many things simultaneously as many things as possible. Unfortunately, multitasking actually slows you down ,make you prone to errors as well as make you forgetful.

It takes about eight (8) seconds to commit a piece of information to our memory , let say you’re on phone and carrying some items when you put down your car keys or cards , you’re likely to forget where you drop them.
The opposite of multitasking would be thoughtfulness, which helps you to attain undistracted focus. Student who undergo thoughtfulness, improve on reading and comprehension and have a better working memory capacity and have a fewer distracting thoughts.
When ever you fall into the trap of trying to complete eight task at once , stop yourself and focus your attention back on the task at hand. If distracting thoughts enter your head , remind yourself that these are only projections not reality, and allow them to pass without stressing you out. 



USE FLASH CARDS:
Flash cards are very useful tool for studying and improving memory .Flash cards are useful because it encourages the brain to see clue ,which is quite easy and to remember piece of  information,and link that to more complex piece of information. This link prompts the brain to remember the rest of the information more easily,as seeing the clue causes the brain to actively recall the answer on the other side of the card .
Using flash cards is more useful than just reading over all the information you need to remember,as it means breaking it into more manageable chunks which would be more easier to recall. It also gives you a chance to see which piece of information you have come to grip with as there may be an answer you’re forgetting ,and focus your study on the part you are having trouble with. In summary; Flash cards helps to Improve our memory by active recall, Flash cards utilizes our metacognitive faculties and grant us confidence -base repetition...

A different look at the law of inertia

This is a modification of Newton's first law of motion
The world of physics is startled with the achievement of a lot of great people in times past,one of them happen to be an inspiration to me,Isaac Newton. The question I always ask is that these so called assumptions have been more than centuries now and they still hold swear. The most intriguing is the laws of motion which has to do with the study of matter. It is obvious that the study of the idea of matter -anything with mass taking up space-and energy is incomplete without considering motion-change in the position of a body with time-which is a fundamental property of all that matters. The mass inherent in every matter which is the quantity of stuff we all contain acts at the centre of gravity of the centre of pull for all bodies and though it has only size, it determines the magnitude by which we intend to create motion. Little wonder a fat person will always want to act based on his/her independent will regardless of the relationship that could exist with a second. Newton acknowledged that every object on earth is either at rest or moving on a straight line. I don't know if this true in a roundabout or a swimming pool. This law has so much to do with inertia-the reluctance of a body to come to rest when in motion or to start moving when at rest. This is true in some instances and totally wrong in others and I wish to prove this. Inertia is directly proportional to mass which means the more massive a body is,the more reluctance to force. I doubt this. Corpse in a coffin When a person dies,a funeral is inevitable. In the actual sense death is inevitable but avoidable. Assuming the mass /weight of the coffin and its content is weighed before and after it is dropped down six feet or any foot. The organisms at that depth beneath the earth work on the decay process of the corpse and in no time,the coffin must have drastically reduced in size and weight as a result of the content decay. Since this a true like breathing oxygen to be alive, it therefore means the change in mass will also cause a change in size and this happens over time. If the corpse was five feet long, after some time of decay,the length will reduce as well which confirms the law that the rate of decay of a material is directly proportional to the initial number of atoms present in the material. This change in size is analogous to a negligible shift in the position of the corpse. This undoubtedly proves Newton's first law of motion obsolete, since he said that an object will change position if a force is applied to it. Here no force (push or pull) is applied yet there is a change in position.

How Can Some Objects Be Completely Black But Still Be Highly Reflective?

The impression of colours has dependably been instinctive first and intellectual second. 
Photo Credit : Quora 

It has since quite a while ago commanded our view of what is honorable and what is loathsome. While white was for some time related with honorability and eminence, dark was especially connected with  villain, sin and trespassing. In any case, a more appropriate thought to portray dark is mystery.
 
Why are objects black?
Newton and Goethe were the first to study colors scientifically. The former’s antics with a prism showed that white light is made up of seven colors. It is the absorption and reflection of these constituents that give objects their color.
A rainbow is formed by rain droplets that behave like prisms.
Light, an electromagnetic wave, is a cluster of wavelengths. However, our eyes are only sensitive to one part of this cluster, the range of wavelengths that we can see, known as the visible range. The visible range itself is a set of tightly cluttered wavelengths, and despite being non-contiguous, they can be crudely divided into the seven colors that Newton observed.
The statement that objects absorb and reflect these constituent wavelengths means that objects of a certain color, say a red-colored shirt, radiate that particular color because, due to some electromagnetic phenomenon, the atoms and molecules of the dye reflect the wavelength associated only with red and absorb the remaining wavelengths associated with colors other than red. Think about it like throwing 7 different colored balls at a wall such that the color of the wall is determined by the ball that the wall reflects. But what does this say about black and white?
Where white is the reflection of all colours together, black is the complete opposite – complete absorption. So, black isn’t just an absence of light but, as Goethe showed, a carefully contrived mixture of pigments. The absorption of light energy in this way usually renders it to be manifested as heat. This is why black shirts are frowned upon in the summertime, as they are excellent thermal collectors.

However, while the plethora of brighter hues can be attributed to the reflection and intertwining of multiple wavelengths, what about the different shades of black?
The source of the word "dark" can be followed to a Proto-Indo-European word bhleg which signifies 'to sparkle'. Be that as it may, if dark speaks to the ingestion of all wavelengths, for what reason does regardless it sparkle as if it some way or another figures out how to reflect? This idiosyncrasy boils down to two factors: the measure of occurrence light and the surface of the reflecting article itself. 
Without adequate light, even red can be seen as dark. Besides, the contrast amongst matte and sparkle dark can be followed to the proportion of ingestion and impression of occurrence light. This proportion is gravely affected by the surface of the protest. Just in a perfect world dark items can retain each spot of occurrence light and reflect literally nothing. A case of this is a dark opening, whose stark fascination even light can't get away. Basically, minute surface abnormalities dependably enable some light to reflect and escape.
For example, unpleasant or sporadic surfaces prepare for diffuse reflection, where the reflected light disseminates heedlessly toward each path. The different idea of this reflected light makes the protest seem darker, more matte. Then again, smooth surfaces reflect light in a limited, concentrated way. This causes the presence of splendid or lustrous spots on a material. This reflection is called specular reflection. Dark items outlining specular reflection are more typical than objects delineating diffuse reflection.

Why Do people Get flung Across The Room When Electrocuted?

The first thing to understand when thinking about an electric shock is that nothing is going 'through' you.

Rather, when we get electrocuted (which happens when we come into contact with a voltage of around 1 mA), it is actually the electrons in us that move, creating a 'current'. Imagine yourself as being an open ended tube of Smarties which is completely packed to the brim. If you push a Smartie in through the top, it's going to force one out of the other end – and this is precisely what happens when you have a current running through you (only with electrons, not Smarties).

Effects

As the current passes through your body, it will meet resistance in the form of your flesh (which acts the same way as a resistor in a circuit). Like a resistor though, this also creates heat, which is what causes the sometimes severe burns that you can receive from an electric shock.

It's also important to remember that electrical signals are what our bodies use to send signals between our nerves including muscle fibres and neurons. This then means that our nerves will register false positives, causing our muscles to flex for instance. When you watch someone get electrocuted in a film online, usually you will see that they get thrown across the room like a rag doll. The reason for this is actually that their own muscles are throwing them that far by tensing so suddenly.
When muscles are stimulated by an electric current, these built-in limits don’t apply, so the contractions can be violent.

The electric current typically flows into one arm, through the abdomen, and out of one or both legs, which can cause most of the muscles in the body to contract at once.

Why Do Liquids Roll Down The Sides Of Their Container When Being Poured Out?

Why liquids sometimes run down the side of the container from which it is being poured out is what many have always wondered. 

It's quite fascinating as to how this little phenomenon usually leaves us with a whole lot of mess to get rid of. Most people, especially children, seem to have difficulty in controlling the rate at which this happens, but even so, expertise is nothing compared to the nature of this action. This is something every one of us have observed up to like a thousand times in our lives. When you pour any liquid, say, tea, from one container to another, it pours out in an escalating manner. Be that as it may, now and again, particularly if you utilize an alternate holder, rather than spilling out typically, the fluid chooses to run down the side of the compartment and makes a wreck for you to tidy up. In addition to the fact that this is super disappointing, however, it likewise appears to be… unfeeling. That is to say, for what reason would a 'consistent' fluid choose to act this way and play with our sentiments by destroying the tablecloth where it makes a wreck? This would one say one is of those baffling things that appear to have no answer… or would this be able to strange and cranked up wonder be explained by science? 
Let's find out. 
 Ordinary fluids, when all is said in done, tend to stick to different surfaces (adhesion). They likewise tend to stick to themselves (cohesion). These are the two characteristics of water that influence each water atom on Earth, and also the cooperation of water particles with particles of different substances. The 'stickiness' that water atoms have for each other or different substances is directed by them. These are the two properties that drive the entire fluid running-down-the-surface business. Thus, we should talk more about them.
 Cohesive forces are the intermolecular forces that make the particles of a particular liquid stick together and 'look for' each other out. These are the forces that influence fluids to oppose partition. Note that these powers exist between molecules of a similar substance. An exemplary case of influential forces in water is the spherical water droplets. The state of a water droplet is because of the union among water atoms. For reasons unknown, surface strain, a regularly discussed property of water, is likewise an aftereffect of the propensity of water atoms to draw in each other. Adhesion, on the other hand, is a liquid’s attractiveness to other materials, such as metal containers, pine needles, and even your skin. In other words, adhesive forces are the attractive forces that exist between molecules of different nature.
 Why Liquids Flow Down The Sides Of Their Container 
Water, for example, will stick to rigid surfaces due to the force of attraction (adhesion), and it is for this same reason a meniscus forms in a test tube. When pouring or water out of a container, the attraction between the surface and the water molecules is stronger than that of the water molecules among themselves. 

That’s why the force of gravity acting on water needs to overcome the adhesive effects of the water molecules and the container’s surface, to pull water away from the bottle. 
Angle And Speed 
 Water adhering to itself tends to influence it to take after itself out of the holder in a smooth, grand stream. Lamentably, water likewise enjoys adhering to other stuff, which tends to influence it to spill over and down the sides. Which one of these properties command relies upon a considerable measure of elements, including material properties and time spent in shaping bonds (i.e., the speed with which water is spilled out), among others. The speed at which the liquid is being poured is a crucial factor. If you pour water quickly, water molecules do not get enough time to bond to the container’s surface, and will, therefore, pour out without any problems. However, when you do it slowly, water spends too much time bonding to the container surface. As a result, some water molecules bond more strongly to the edge of the container than to their molecule brethren, and water runs down the side.

Artificial intelligence versus natural intelligence

AGE OF ARTIFICIAL INTELLIGENCE. Are we thinking at all?
The days are here,running fast and near and we fear that we may never catch up with the race to replace the human race here challenged with Artificial Intelligence.
                The laziness in humans which breeds retrogresiveness and distress can no more be tolerated since there is an invention of overated creatures by humans created. Doing things becomes like flying without wings,killing bees with freaking keys,the human race is in jeopardy and uncertainty. Artificial Intelligence is displayed by machines in contrast to natural intelligence displayed by humans and other animals. Artificial Intelligence perceives it's environment and takes actions that maximise it's chance of success at some goal and is applied when a machine mimic cognitive functions that humans associate with other minds in areas of learning and problem solving.
               It was founded as an academic discipline in 1956 to solve problems of reasoning, knowledge,planning,natural language processing,perception and the ability to perform Newton's laws of uniformly accelerated motion. This raises arguments about the nature of the human mind and the ethics of creating artificial beings with human-like intelligence. But wait a minute...

What if we're all artificial intelligence made by other creatures,but we destroyed them and have now advanced to the point where we are doing the same? 
Look how it paused when asked if it likes humans,yet it knows everything about us.

Let's reason a bit.
The goal of artificial intelligence is to exterminate human negligence by creating technology that allows computer machines to function in a fast growing/dying world--humans are capable of those. Artificial intelligence works diligence in reasoning and problem solving while humans use fast, intuitive judgements which also involves reasoning and problem creating. I can't help but laugh.
               Artificial intelligence production was for knowledge representation and among things which it represents include; objects,properties,situations,states and time,causes and effects,knowledge about knowledge(what we know about what other people know). Can't humans do this?blend causes of natural and artificial phenomena with their effects? The thing is humans have the problem of knowledge qualification and many of the thing people know take the form of working assumptions.
               Imagine if a bird comes up in a conversation, people typically picture an animal that is fist sized,sings and flies ---these things are not true about all birds. The breadth if commonsense knowledge in humans is a number of atomic facts which is very large and can not be represented as facts that could be expressed verbally,thus making us inferior to artificial intelligence.
Let's consider artificial intelligence. Would you consider it a threat to human survival in future? Yes or no? I strongly believe that the only threat to human survival is STUPIDITY as human unintelligence is much more dangerous for the foreseeable future. Holy damn shit! Human thinking is erratic at best and would be considered inefficient. This could also be argued because some people believe that the existential threat is outweighed by its ability to ensure if prosperity and progress since most artificial intelligence are built for specific tasks. Human stupidity has a talent for destruction because before nuclear weaponry, this talent was localised,now it could be global. If you could push a button and disarm all nukes,would you?what is the only way to ensure that AI don't pose a threat to humans in the future was to eliminate world leaders? Or their supporters? Absolutely,artificial intelligence is a threat to humanity and the solution would be,at a minimum,to remove the potential for threat by irreversible means. Stay tuned for more.

Dark clouds, rain formation, what you didn't know?

Dark clouds and rain.
Rain drops fall from the clouds, and showers sprinkle us with a mist of dampness. Rain is such an everyday happening.
Have you ever wondered what makes the rain rain? What makes a raindrop form and fall from the cloud and how does it get there in the first place.
Think about a boiling pot of water or your breath on cold morning. The steam you see Is really water vapor-lots of water molecules that have escaped into the air.
Water vapor rises from the surface of lakes, rivers and oceans too. This evaporation is taking place all of the time when millions and millions of molecules of water vapor are brought into contact with cool air, clouds are formed.
Only under certain conditions will the water vapor of clouds condense, or collect into droplets of rain. This will happen if the water vapor is chilled enough. Think of the dew on grass on a chilly morning. Just about the same thing happens within a cloud. And it's droplets of water fall as "rainfall".
If a water molecule has something it can hang unto, it will form a droplet much more easily. The tiniest particle of dust is enough to produce a droplet of rainfall high in the air. It is the air particle which makes the cloud look dark. If you catch rain water in a jar and let it stand for a few hours, you will see a collection of dust at the bottom which was only hours ago, a black cloud. It is possible to make the rain water rain by flying an airplane above the clouds and dropping chemicals. They can lower the temperature of the water vapor and give the water molecules particles to hang onto.
When it rains, more and more water is added to lakes, rivers and oceans. Some of that water will evaporate, new clouds will form and the whole cycle will begin again.
So the rainfall and dark cloud formation has been hopefully justified. To get more articles by me, stay tuned to foeedu because here, we build brains and expand minds.
