Climate Change Deniers Eat This!

In my volatile opinion

A recent US study, conducted by a leading university research institute, has revealed a clear link between the mating rituals of blue monkeys and Caucasian elderly couples.

Whoa! What! Okay, let's just stop it right there. What has just happened (hopefully) is that I have used the little authority I have as an aspiring science writer and columnist to imprint an idea in your head which has the potential to evolve into an opinion, part of which, will define you and be your weapon in your next battle of the wits.

As the title of this column suggests, I have a very volatile opinion on just about everything. This is because of all the 'excessive' reading and viewing of National Geographic Channel that I subject my puny brain to. My opinion on any given topic, from The Big Bang Theory to World politics, changes as much as my exposure to new info continues.

Now, I am among the lucky few who let the availability of reliable information shape my opinion. There are some others who have stubborn tendencies that when their opinions are attacked, go into defense-mode and take these challenges personally, as gratuitous attacks on their person. God bless their poor souls. A great example being Young Earth Creationists who maintain the age of the universe is no more than 10 000 years despite the overwhelming evidence contradicting this notion.

Some people want to keep their opinions as they have made them part of their identity and in this way keep them through a misguided attempt at self-preservation. This, in my opinion can be very dangerous in cases where the person harboring this false opinion is in  an authoritative position in that his opinion can get viral and infect a whole community and in the worst cases put people's lives in danger.

Whilst that last statement may seem a bit dramatic, it begs that I paraphrase an example I made in a previous column. Remember the doctor who falsely stated a link between the MMR vaccine and autism in children? Well, as stated before, his legacy lingers on even today, as many parents in the UK and the States are reluctant to take their kids to be immunized. Many only find the flaw in their ways when their kids succumb to the preventable diseases the vaccine is meant to guard against.

As many false opinions are generated, this one originated from a qualified medical practitioner who wrote a scientific paper on his findings. And what's a layman to do when an expert says stuff like this? Advertisers use the same principles to market some products during those daytime infomercials.

Another notable example is the inclusion of climate change deniers in the US government. This may not seem like much but the policies that come from that country influence the rest of the world in terms of climate change. As it has already been shown, climate change is real and those who are in line to suffer most from it are those who contribute to it the least.

Our opinions on the world we live in influence the way we do things. Whether it might be deciding on the quickest route home or casting that all important vote, it is not hard to imagine how all these things can have lasting implications on the way we live. It is advisable that one takes all informational stimulus with a pinch of salt

If one should take away anything from this column, it is that you should not believe a word of it. That said, I hope you don't pin anything on me when you lose an argument over something I've said when you find out it isn't the truth. Oh, and by the way, that first statement is a pile of hogwash. I used it to make my point.

Post column: do not believe everything you read or see, except this statement.

Trouble Sleeping?

Two of my close friends are suffering from insomnia and since

learrning of their predicaments, I've been doing a little reading on

the subject in an attempt to help them as promised.

Now, its very easy to find remedies for such 'ailments' on the world

wide web by simply connecting to Google. I could've just left them to

that, but then where's the fun in that? Anyway, there's a lot of folk

remedies whose unnamed authors swear by. So, this makes it rather

difficult to decide on ones that work. I decided to mention a few

favorites I found and those that are practical.

Some that stood out for me include "sleeping with your head facing

North" which tells me that your sleep pattern is somehow affected by

the magnetic field of the Earth (even though the remedy fails to

mention whether it's true or magnetic North), and this may require a

change in deco as soon as you figure out which way is North.

Another one which I liked says that you"mustn't use your bed for

anything other than sleep or sex". But the question remains, what can

MV and N (that's what I'll call my two friends) do regarding their

sittuations?

Well, it helps to know what kind of insomnia one has before attempting

to 'cure' it. There's acute (primary) and chronic (secondary)

insomnia. The former lasts less than three nights and the latter can

lasts for many more nights and can drag on for a couple of months.

Now, the acute kind is very easily manageable as it has causes such as

stress and tension caused by the loss of a loved one, losing a job,

anxiety for exam results (MV?) and various other related causes.

Anyway, the more serious kind, the chronic insomnia could be caused by

underlying mental and physical ailments such as (clinical) depression

and other illnesses. I suggest you consult a doc if you suspect you

have this kind.

Some medications can also interrupt one's sleeping pattern, of note is

treatment for high-blood pressure, and for asthma.

N said "I drug myself to sleep" and that this has been going on for

months now. Unless these drugs are issued by a qualified practitioner

having diagnosed you of chronic insomnia, and having given you these

for temporary use, then I must tell you that over-the-counter sleeping

drugs can be dangerous overtime and they eventually lose their

effectiveness.

Problems, problems, but this still keeps you up at night and you need

solutions. You could try a few simple acts that are said to improve

your sleep 'hygiene'. The great thing about them is that they make

perfect sense and they're easy to do!

They include: exercising three or four hours before your scheduled

bed-time, a little reading to tire yourself up in case you wake up in

the middle of the night, keeping the same bed-time and wake-up time,

drinking warm milk before bed (yup, it works!), having your supper an

hour before sleep (a light snack in bed also helps), listening to

relaxing music (not depressing) and for all those worriers out there

(ladies) try writing a to-do list as that may help tame the worry-wort

in you.

I really hope this helps, and if you should find that it doesn't, I

again emphasize consulting a specialist as that might reveal something

deeper...my biggest worry being clinical depression.

If push comes to shove, counting sheep still remains an option. Goodnight.

God and Science, the real story (FIXED EDITION)

Up to now, I have been trying very hard to avoid mixing my writing on
science with issues of God and religion. Nevertheless I get inundated
with false opinions regarding science and how it is at loggerheads
with the existence of God that this has got me thinking. Where do all
these ideas, these notions that believers in science are disbelievers
in god? I am of the opinion that these judgments are baseless and very
dangerously contagious in that they antagonize, in a sense, the
scientist as an automatic atheist. I must also say that atheism is not
a bad thing.

First of all, I am a scientist in training and a firm believer in the
existence of God. This does not, however, deprive me of an inquisitive
mind or the urge to question everything and everybody. In my naïve
years, I used to be amazed by scientists, especially astronomers, who
openly believed in a god. I remember asking myself how this could be.
I mean, does not the scientific evidence contradict any notion of the
supernatural, or the existence of a higher being, and so bury God with
all the other fairytales?

I have learnt, personally, that there is so muchmore to it than that.
Personally, I started liking science when I saw how beautiful the
world, nature, the biosphere, planet earth and the rest of the
universe was. I was helplessly drawn into it by a childish curiosity
(my biggest asset) and my search was rewarded by absolute bewilderment
as I held a book on Time and Space. The truth is, most of us start off
with mere interest and curiosity, and then comes the questions from
the "wise ones". A cousin of mine has asked me on many occasions since
she learned of my interest in astrophysics whether I am looking at the
stars to find God. She proceeds to jokingly show her disapproval on
this prospect citing it as a crime of faith and that I should have
faith in the big guy's existence.

My next-door neighbor has also asked me a similar question, but in her
case I always feel a genuine sense to know more. This was proven to me
when she invited me to her house to view something on the television
that she thought might interest me. Now, she is a retired nurse and I
could not help but wonder what she thought might interest me. When I
arrived, I saw a morning news show displaying images of the first
stage of the Square Kilometer Array –a joint scientific project
between South Africa and Australia- and some scientists, who were
heading up the project, discussing its significance in putting South
Africa on the global scientific platform. I ended up spending the
better half of an hour watching with her and explaining how important
the project is and expressing my gratitude for her having brought my
attention to the broadcast.

Now, I have always tried to separate God and Science, but it has come
to my realization that the two are actually inseparable. First to
answer the question of whether I am looking for God when I am looking
at the stars and whether I have come to any breakthrough in my
fruitless venture. Yes I have, I see God on every cloudless night when
I unstiff my neck to look up and appreciate the beauty of the stars
and the many other objects in the sky. I see God in the blogs that I
read that show me how stars are born in the wake of huge star deaths,
how vast the cosmos is, the incredible history of the Earth and I see
God even its prospective demise. Now, my kind of God may not be your
kind of God, and as I said, this is my opinion and seeing God in the
beauty of nature is what makes me happy.

Finally, although mathematics is not my most favorite of subjects (far
from it) I do appreciate its indispensible importance and in it,
again, I see God in the perfection of prime numbers and the mysterious
intrigue in the Fibonacci Sequence. I must admit that any notion of
God the reader has is unlikely to be affected by my one column, I do
however hope that it will prompt one to employ an open mind and to
question everything and everybody except your mother…never ever
question your mom.

Shedding Light on Dark Matter

Sometime in the 17 th century, a man was supposedly hit on the head by an apple, ripe, that had detached itself from the tree he had been
sitting under. This story should be familiar to any self-respecting
physics student–myself included-. How true this story is, or the less
painful version of him merely observing the very hard fruit falling to
the ground, is subject of little importance. But the events that
followed have affected every aspect of how we view the world today.
We see stuff fall to the ground all the time, it really is no biggy. I
mean, it's just a fact of life; things will fall. In that fateful
century, however, in an unplanned vacation induced by an epidemic of
the plague that ravaged parts of Europe, a very smart scholar used
this time very wisely and out of it came the answer to the most
unasked question of all time: why does stuff fall down? Newton, today
known to many as the greatest thinker of all time, pondered this
question (in more formal English).
After countless hours he came up with a very nifty equation, stating
how gravity is a force that pulls stuff together, and how the strength
of this force decreases by a square of the separation of these two
objects. He also explained the motion of the planets and that was
that. Well, it's all good until you ask the question: what is gravity?
Of course, it is a force that pulls objects together, thus creating
the effect of the less massive one falling toward the one with greater
mass.
The trouble with this answer is that it just doesn't explain what
gravity is, it just explains what is does. Sort of like explaining
wind with the bending of trees. Einstein came to the rescue with his
famous theory of general relativity which explained how massive
objects distort the space-time around them, thus explaining the motion
of objects in such gravitational fields. He proposed another way of
looking at this force and in this way solved a long standing riddle of
the peculiar orbit of Mercury.
It seems there is an adversary of this universal force, a force that
does the complete opposite of what we've known gravity to do; it
pushes things apart. After the expansion of the universe was
discovered, an even greater anomaly was observed. The expansion of the
universe was expected to slow down but the discovery that this
expansion is actually accelerating, caught those who observed it by so
much surprise that at first they thought they'd made a mistake
somehow.
Observations have shown that there's stuff literally appearing out of
empty space and pushing galaxies apart. It's an energy that pushes
incredible masses apart; we literally have no clue what it is, despite
studying it for over a decade. It's so illusive and so little is known
about it, save its effects, that it has been termed: Dark Energy. Not
related to the enigma of Dark Matter, its sexy adjective reminds us
how little we know about it.
In a recent scientific endeavor, a very sensitive satellite was used
to scan through the sky in all directions, in search for what is
essentially the afterglow of the Big Bang. The result was a dirty
looking rugby ball of a map that is the holy grail of cosmology known
as the Cosmic Microwave Background. Now, it gave many results of great
importance that as I am typing this I am contemplating a draft of the
column solely based on these topics.
Now, one part of the result shows that dark energy makes up 68.3% of
the universe, leaving dark matter being 26.8% and normal visible
matter a mere 4.8%. I find it fascinating that this stuff, this force,
this energy we know so very little about makes a bulk of the universe.
This mystery of dark energy is just one of many that keep me curious
and reminds me of how much more there is to know out there. The
universe holds many more secrets than we thought, and the more we
know, the more we realize how little we do know. For every one
question we answer, many more questions appear.
Now is an excellent and very exciting time to be an astronomer, and a
South African one at that. Also, being a science journalist and
enthusiast puts one at the forefront of what projects such as the SKA
project will produce regarding this anomaly and many more mysteries it
will answer, and many, many more it will create!
And by 'we', I am referring to all those curious and have insatiable
appetites to know more.

Isilimela

I would like to take this opportunity for which I am very grateful for
to honor a man whom I have only met in his works. Anthony Ferrel is
the author of the popular astronomy book: Skywatching,which comes
highly recommended for professionals and enthusiastsalike. I found the
book during an unguided exploration of the local library, in my very
younger years when I was stilltrying to find my identity, so to speak,
in the kind of booksI like.
This book is the very root of my being today somewhat of avoracious
reader and knowledge seeker of sorts. So, many years later I was very
lucky to meet a former student of his, whom, though not surprisingly,
spoke very highly of him. I remember vividly how I was still
'charging', soaking up the morning sun on a stoep in the very crisp
winter morning at the South African AstronomicalObservatory in Cape
Town, when this former student informed me that the great professor
had died a couple of years back.
Very few people get to meet their favorite authors, and I'msure that
those who do treasure such moments. I hadn't read the book in a
longtime but knew its contents, page by beautiful page by heart, and
just meeting one ofhis students who knew him personally was the
closest I had to meeting him. I imagined how he might have been in
thevery spot I was standing when I visited the observatory in
Sutherland when one evening, as he so vividly describes in the
introduction in his book, he saw the few constellations that had
already started appearing in that twilight aftersunset.
I even remember how he described each of them they that he saw as if
they were people and drew for me a picture of the sky that I'd never
seen. It was like discovering something that had always been there,
right over my head, a canvas in which a higher being may have reserved
to show His best works. The illustrations and simple English he used
enthralled me and to this day, I try to follow suit as best I can. One
of the topics he wrote about revealed to me something I never thought
was possible, that Africans are astronomers in their own right, or at
least used to be.
I have always had this idea that looking up at the stars was a western
thing, and many of my peers do away with such stupidity. Anthony, in
his book, opened my eyes in many respects. This particular page has
this Nguniword that caught my then very curious eye: Isilimela, and he
wrote about it somewhat along these lines. This term was and still is
an essential facet in the Xhosa calendar. It marks the beginning of
the agricultural season and the time in which initiates 'go to the
mountain' as they say.
It begins when a group of stars known as the Pleiades cluster in the
Taurus constellation reappears in an eastern twilight. This also
brings light, to the people, who I consider the earliest (African)
astronomers who were entrusted with spotting the reappearance of this
cluster, this Isilimela which was then very important in that it
marked the best time in which the season could begin. So important was
this task that the first person to spot itwas rewarded with the
slaughtering of a cow with his name held in great esteem.
I find myself thinking how this vital skill was passed down orally,
with no books with drawings and beautiful pictures to spark the
imagination, but poetic and mythical descriptions that would
flamboyantly paint the picture in the student's mind. Iimagine a crisp
night, an old man, young boy on his lap, sitting on a rock in the
twilightas the cluster slowly appears and the wise one pointing out
the twinkling beauty.
In this, I see a cosmic connection, and an African oneat that. The
night sky is beautiful, and finding out whatmakes such beauty, is part
of the adventure of being an aspiring astronomer. It is my ancestral
right. I am what I am,and are to be, because of books like Antony
Ferrel's. And in him, I am eternally grateful.

The Truth About Immune Boosters

My very loving mother has advised me against writing, let alone publishing, this very innocent column in fear of some kind of retaliation from the local syndicate whose livelihood I'm about to
attack.

I ergo write this under duress, and if it so happens that the gentle reader is reading this from the musky smelling pages of a newspaper, do not forget the great lengths and the many nights of contemplating the risks involved in order to bring you this piece of cut-throat journalism! No fear, no favor. From the time of print, I will be probably watching my back (I need a periscope), and avoiding open drinks (as I should always), so as to live to write another column that might cause me injury. Oh the humanity!
Here we go.

As I sat down to write this, I dreaded the many hours of research I would have to put in in order to bring you this exclusive. Thank God for Google and other smartasses like me, reports of these
quacks have been all over the internet for many years now. Just a few minutes out of your lunch hour to Google "immune booster hoax" will give you more than enough reasons to stop buying these untested concoctions that are made of who-knows-what.

Like the authors of the New Testament, I myself have an agenda in writing a column on this
particular topic. I mean, I could have just written about the president's private parts
of his life (his house), how rich people can make the government look away (Guptagate) or how South Africa has collectively numbed itself against rape and domestic violence. But no! I wanted to write about something that's closeto my heart. I'm a scientist in training and a great enthusiast of the truth. So, when I see the truth being twisted, screwed, spat on, bottled and labeled to look like the truth; I get very angry and go hulk on your ass!

What gets my lymphocytes into a real fit is the blatant untruth presented by these dodgy looking companies who sell these so-called immune boosters. What does that even mean,'boosters'? The truth (which the reader can find on the net) is that the immune system of a healthy person is an evolutionary masterpiece that does not need to be improved, boosted or re-engineered. It is a very complex system that we vaguely understand, and how these concoctions claim to improve it, leaves me scratching my head as I slave over these medical textbooks and reputable websites.

What's the big deal? This stuff can't kill you, right? Well… not directly. For the first time, this column is about to become very opinionated, maybe even subjective, I dare say! Winter's coming, and
this muti is being advertised as protection against the coming flu season. The trouble with this is thats the average consumer, who is not exposed to the possibility of immunization through vaccination, might as well buy the much cheaper immune boosters that promise to prevent diseases I've never heard of and bring your long lost spouse back to you among other benefits.

Now, vaccines do not boost your immune system as such, but what they do is actually give your system a sort of a heads up of what's to come in the coming season. How it actually works is that they inject you with a weakened version of the virus (such as for measles) and the immune system reacts as if it is facing the real deal, and the result of this is that the immune system is ready next time that strain of
the virus attacks.

That's how one is protected. There was a scandal in Europe in 1998 in which a scientist, Andrew Wakefield, claimed to had found a link between the MMR vaccine and the development of autism in children. Parents, on the authority of this scientist, avoided taking their kids to be vaccinated and this in turn put many lives at great risk.

The results were later rubbished as their instigator was later found to be extremely biased (he was developing an alternative vaccine) and he had altered his results. The consequences of his actions have are still prevalent even today with parents who still will not vaccinate their children based on this blatant untruth. The media was also criticized for its role in the irresponsible reporting and having not covered the rubbishing of the results.

I hope it'll never come to this. But what I have seen are these adverts that use scientific terms and facts in saying why the immune system is important and why pathogens are so dangerous. They then proceed to tell you how this sugar water they call a miracle is going to help you protect yourself from this flu season. So how can a layman stay unconvinced after someone who knows science says it is?

I am simply against the twisting of the truth especially when people's lives are at stake. I don't like what I'm seeing. The remnants of a denialist government who had an uncanny fetish for beet-root.
