Preventing Hurricanes: Duty or Instructions?

Recently, we have had so many natural disasters. A reoccurring one is the hurricanes.

Hurricane irma affected Florida in the U.S.A. killing more than 16 people and affected the power supply, making sure that about 2 million people lived without electricity.

A hurricane is a type of storm called a tropical cyclone. It forms over tropical or subtropical waters. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and north eastern Pacific Ocean. A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds , and a spiral arrangement of thunderstorms that produce heavy rain.

America has been hit by 3 hurricanes recently and they include: hurricane jose, harvey and irma.

Now what causes this disaster??

Warm ocean water plus the Earth's eastward rotation.

This is the simplest answer.

Scientists have already warned that the response to the recent hurricanes shows how terrifying and unprepared the world is for the kind of extreme weather events that will become very common as the Earth gets hotter.

How can these be prevented??

Take care of nature and your environment properly.

It's more than an instruction. It is a duty.

Evolve Scientia: Life without The greens

Welcome to another evolve scientia release. I felt the dire need to
share my views on this amazing topic "Life without the greens".



Some days ago, while preparing for my laboratory work I noticed a
scale fell of my eyes as I observed the vegetation surrounding the
laboratory. Then I thought "Can I live without The greens??". I began
the quest and
these are my findings.




The greens are the plant cover of our Planet earth. Why are they useful?




They are basic food staples, land animals, fishes and man feed on
plants. Plants are used as state and national emblems as well,
including state flowers and state trees. Trees from ancient times are
famous and are revered. Plants hold world records as well. Often,
plants prominently figure in literature, religion and mythology





Some plants are useful in medicine in making drugs, concoctions and
anaesthetics for surgical operations.






Plants also provide animals with shelter, produce clothing material,
medicines, paper products, reduce noise levels and wind speed, reduce
water runoff and soil erosion. Coal is also produced from plant
materials that
were once alive.





Cash crops produce income for farmers. Peanut oil comes from peanuts,
corn oil comes from corn and olive oil comes from olive. Cash crops
also include
typical products of agriculture like rice, rye, wheat and corn. Cocoa
plants give us chocolate, coffee plants produce coffee and vanilla
plants produce vanilla flavoring.






Many beverages and drinks like tea and cola come from plants. Other
cash crops include cotton, vegetables, fruit, lumber and rubber from
trees. For an overall ecology, plants are also important. The roots
prevent soil erosion
and when plants undergo photosynthesis, they use up carbon dioxide and
give off oxygen, there by maintaining the oxygen cycle.

Gerontology: The advantages of Old Age

 Gerontology is the branch of science that deals with the problems of aged people. The aged  are very important in our societies . They are indispensible and will forever remain relevant to our societies.

When does old age begin?
The poet Dante believed old age started at 45. A survey of the British public concluded that it starts at 59 – the older the respondent, the greater the number of years they considered old. But the United Nations and most scientists define it as any age after 60.

Africans are very respectful. Most elderly are kept well and taken care of .For Koreans, the 60th and 70th birthdays are prominent life events, which are commemorated with large-scale family parties and feasts. As in Chinese culture, the universal expectation in Korea is that roles reverse once parents age, and that it is an adult child's duty — and an honorable one at that — to care for his or her parents

Like the Chinese and the Koreans, the Japanese prize filial piety and expect children to dutifully tend to their parents. But Japan also faces the unique problem of tending to an increasingly elderly population.
According to Social Gerontology: A Multidisciplinary Perspective, 7.2 percent of the Japanese population will be 80 or older in 2020 (compared to 4.1 percent in the U.S.), which will likely lead to a host of new problems for the country. Adult diapers are already outselling baby diapers, and the pension system is on course to dry up.

1) Brain plasticity.  It was once believed that we were born with a certain number of brain cells that slowly died off as we age.  Science now knows that our brains continue to grow neurons as we age and can reshape itself in response to what it learns. Even learning to juggle, learn a new language or play an instrument can cause significant brain changes in hearing, memory and hand movements.  Plus, studies confirm that our vocabulary not only continues to grow as we do, it become richer and provides more subtle ways of expressing ourselves.  As long as we use it, we won’t lose it!


2) Less negativity—higher self esteem.  Researcher Ulrich Orth from the University of Basel studied thousands of 18 to 89 year olds and discovered that regardless of demographic and social status, the older we get the more negativity diminishes and the higher our self-esteem climbs. 

3) Clearer priorities.  Studies done by Michael Marsiske Ph.D. suggest that older adults tend to perceive time in a way that makes them “increasingly aware that our years on this Earth are limited.”   He goes on to say that, “This awareness helps explain the choices that older adults tend to make: to spend time with a smaller, tighter circle of friends and family, to pay more attention to good news than to bad news, and to seek out positive encounters and avoid negative ones.” In other words, aging helps us let go of the trivial and focus on what is most important.

So value the elderly.

Overtime, our world seemed not as it was....Although change is constant but most times isn't really shocking or better said fascinating as the internet.

The Superman Memory Crystal

I got up from my bed thinking it was business as usual, then I looked
around no one was at home. It seemed I had over slept, but how could
this be possible since my alarm was set for 7am?


Well, I could not say until I saw my phone. I then tried to switch it
on but alas! I discovered that my phone crashed during my journey to
the dream world.


What a futile digital world!

Before going to bed, I downloaded some videos and materials to use
during the day but now it is all gone.

This little experience of mine is the worst fear of all digital mobile
and computer users. We all worry what if our most precious file get
missing? what if the system crashes? We have even devised several
means of backing up our files but even that is not totally reliable.

How about we having a device that can store data for eternity? I'm
sure you're gonna like this.

Scientists at the University of Southampton have made a quantum leap
towards the development of digital data storage that is capable of
surviving for billions of years. With the aid of nanostructured glass,
scientists from the University's Optoelectronics Research Centre (ORC)
have developed the recording and retrieval processes of five
dimensional (5D) digital data by femtosecond laser writing. This
storage allows unprecedented properties including 360 Terrabyte data
capacity, thermal stability of about 1,000°C and virtually unlimited
half-life at room temperature (13.8 billion years at 190°C ) opening a
new era of eternal data archiving. As a very stable and safe form of
portable memory, the technology could be highly useful for
organisations with big archives, such as national archives, museums,
universities and libraries, to preserve their information and records.


Now, major documents from human history such as Universal Declaration
of Human Rights (UDHR), Newton's Opticks, Magna Carta and King James
Bible, have been saved as digital copies that could survive the human
race.


Coined as the 'Superman memory crystal', as the glass memory has been
compared to the "memory crystals" used in the Superman films, the data
is recorded via self-assembled nanostructures created in fused quartz.


The information encoding is realised in five dimensions: the size and
orientation in addition to the three dimensional position of these
nanostructures.


Currently, scientists are working with relevant organisations to
commercialise it and few years from now, it should be an household
devise but till then, we may have to still endure the pain digital
storage is causing us right now.

Light in the Storms

Near the small village of Kifuka in the mountains of the Eastern
Democratic Republic of the Congo
where the elevation is around 975 m occurs a common phenomenon- lightning.

Lightning is a sudden electrostatic discharge that occurs during an
electrical storm. It is also one of the most deadly natural phenomena
known to man. Very much hotter than the sun at a
about 27000 Centigrade, Six times hotter than the sun.

Most lightning incidents occur inside a cloud, but sometimes it
happens between the cloud and the ground. When they happen inside a
cloud, usually a flash is seen but when it happens between the ground
we have a strike. But it originates from a cloud.

Lightning activities are often observed tens of minutes in advance of
severe weather
occurring at the ground.


Lightning, the sudden electrostatic discharge that occurs during an
electrical storm, is a beautiful but deadly natural phenomenon.

So, we have The Light in the Storm!

Evolve Scientia: The Time Travel Tale

Charles Dickens' A Christmas carol is a book I would always love to read.

Ebenezer Scrooge was transported to Christmases past and future. I was
really thrilled. I found articles like:

1. The clock that went backward by Edward Page Mitchel.

2. The time machine by H.G. Wells.

I had this great desire to know more and be involved in some travels...


Time travel is the concept of movement between certain points in time.
Albert Einstein showed the feasibility of this if a ship is allowed to
rotate the earth at the speed of light or close to it. After being
rotated for long on arrival to the earth all your colleagues will be
much older. With an age range of 45 years.....

It eventually happened...

Cosmonaut Sergei Krikaleve holds the record for the longest amount of
time spent in space with 803days, 9hours, 39 minutes under the belt.
The ISS travelled at around 7.66km per seconds when orbiting around
the earth and due to the high speed and length of
time which he spent in space, the cosmonaut actually arrived back in
earth, 0.02seconds in the future......

I love this, do you?

The Slow Writer in my class...

Welcome to another Evolve Scientia Series! Today, I'll tell you the
story of Mike if you would grab a seat and read through the next few
lines with me.

Mike is a slow writer yet he outshines us in examinations. What's his secret?

Writing is the use of written words to express opinions or
ideas. Writings can therefore be done quickly or slowly.

Dr. Marc Seifer, a graphologist and handwriting expert who wrote The
Definitive Book of Handwriting Analysis in 2008, shared some of the
top ways writing by hand can help our brains beyond just dotting our
i's and crossing our t's.

Writing a calming sentence is a form of graphotherapy, Seifer says.
Jotting down a sentence like, "I will be more peaceful" at least 20
times per day can actually have an impact, especially on those with
attention deficit disorder." This actually calms the person down and
retrains the brain," Seifer says.

In his preface to Daybreak (1887), German philosopher and philologist,
Friedrich Nietzsche recommended the practice of slow reading: It is
not for nothing that I have been a philologist, that is, a teacher of
slow reading; in the end I also write slowly. Nowadays it is not only
my habit, it is also to my taste -a malicious taste,
perhaps? -no longer to write anything which does not reduce to despair
every sort of man who is "in a hurry." For philology is that venerable
art which
demands of its votaries one thing above
all: to go aside, to take time, to become still, to become slow...

For precisely this reason it is more necessary than ever today... in
the midst of an age of "work," that is to say, of hurry, of indecent
and perspiring haste, which wants to "get everything done" at once,
including every old or new book: this art does not so easily get
anything done, it teaches to read well, that is to say, to read
slowly, deeply, looking cautiously before and aft, with reservations,
with doors left open, with delicate eyes and fingers. (Daybreak:
Thoughts on the Prejudices of
Morality, translated by R.J. Hollingdale. Cambridge University Press, 1997)


The testimonials from practitioners suggest that Slow Writing allows
learners to not only think about what they're writing, but also how
they are writing – slowing down the writing process to ensure high
quality.


So, Now I know his secret.

Evolve Scientia: My Sweating Bottle

That afternoon, I had returned from the outing with my colleagues,
very famished. I journeyed to where the refrigerator lay and I
precisely took out a very chilled bottle of mountain dew, from the
refrigerator. While i was about to drink, I received a call requesting
my attention. When I returned, I noticed something annoying, my bottle
was "SWEATING PROFUSELY". Water drops was found around the bottle. How
come?


After my warm bath, I took a glance at the mirror to behold my
beautiful face. Looked too good. I left to the dressing room to look
more exotic. Upon my second glance at the mirror, its surface became
unclear and while trying to clean, my hands became wet... I felt soo
annoyed. What really is behind this?


Condensation is the chief cause. Its the process by which water vapor
in the air is changed into liquid water. In other words the warm air
in the air were cooled by cold soft drink also the warm water vapor
from my body were cooled by the cold mirror surface.


This same phenomenon is the reason behind cloud formation and it's so amazing!

Oneirology and The Science of Dreams

Oneirology has always thrilled me, it really excites me whenever I
study dreams. All these happened when my closest friend, Michael,
claimed to see himself writing in his dream and in reality he wrote on
a paper. Can I say it was just a joke? But I believe Michael to an
extent.


Dreams are series of images, more precisely, a video of scenes that
comes to play involuntarily and unconsciously while we are asleep.

Do you know the most thrilling?

A person can have an average of 3-5 dreams per sleep although some
might have 7.

INTERESTING, you say.

Dreams occur during the RAPID EYE MOVEMENT. It is a stage when the
eyes are moving rapidly and the brain is working actively. A dream can
last an average of 20-30 minutes.

From my study, I have discovered dreams are controlled by our
thoughts, worry and what we meditate on before sleeping. Many schools
of thought believe dreams are controlled by a great influence most
especially, the spiritual...


Dreams encourages creativity and its benefits cannot be overemphasized.


That's why I love dreaming. Do you?

The New America and The Future of Science

The world powers have changed hands. A new government has emerged.
What do we expect? - the wailings of migrants, phenomena, racism, or
peace?

A change in government means a change in systems event to military
intelligence. Many developed countries show their level of development
by their military progress. America's old Cold War rival, Russia, is
giving the world a new cause for concern with its updated — also known
as the Satan 2 missile. According to the state media, which is
notoriously controlled by the Russian government, the intercontinental ballistic missile (ICBM) claims it can travel faster than other missiles of its size (which means it can avoid modern defense systems) and deliver a load large enough to obliterate the entire state of Texas (which means it could obliterate
the entire state of Texas). Why make such a big missile?

Jeffrey Lewis, director of East Asia Nonproliferation Program, explained in a post for that it has to do with Russia's past and present economic troubles.

The former USSR has a ton of leftover warheads and few missiles to launch them.
The U.S. has a similar problem but has chosen to spread those warheads
over many smaller, faster launch sites. Russia doesn't have the money to implement that strategy, so they load as many warheads into one missile as they can.

The new government is a promising one. Lets expect much...

What is the Time?

Over 30000 years ago, man had always wanted to live with
precision. He wanted to be accountable for his day. Organize wars,
ceremonies and official gatherings at a particular time but there was
no uniformity. He had to observe the rotation of the heavenly bodies
(the moon and planets) to "inaccurately" predict time.


So, necessity, the mother of Invention came to play and man had to
invent so many time measuring tools.


The Oil lamps came first. The Chinese monks used oil lamps whose oil
consumption could be measured with time. Thus, time was predicted on
the consumption level of the oil input.


Then, Candle clocks came in line. They are candles that have been
graduated, so with time as the candle melts, the time can be
predicted.


The Water clocks, Sun dials and Hour glasses are later predictions of
time. The question still remains an issue of accuracy however.



So what's this precision about?




We want accuracy as time is very
useful to man.


Today, thank heavens for mechanical clocks which though large sized,
it still ensures accuracy. I thank heavens more for the quartz clocks
for today,
I can say the time is 1:08pm (GMT 1) on the 26th of October, 2016.
