Editors Letter November! The year is by and large over. Where did it go? This is the last edition for this year. Yes, we are looking forward to next year. This edition is focused on summer holidays and what to do.

And also on the dangers lurking out there.

It is also the time for us to wish all the grade 12’s leaving us a ‘happy future’and all the best on this new journey. Life is waiting!

We also welcome all our new grade 10’s who will be joining us in 2017.

This edition is also the wrapup on energy sources. Masiziba has done a great job, but alas, she is also finishing grade 12 this year. HOWEVER, she will probably still be writing for us, so it is not a farewell just yet.

Please read the science article: HAPPINESS. I had a giggle doing it. Eat veggies and be happy!

See you next year!

Good read!

Sybil

Time for poems:

Time is up! The year is out It is the end but It is the beginning Never look back. That was it And something new is waiting With promises and hope and fun And sadness probably as well All things have an opposite The end is the beginning And today is the first day In the rest of your life

Sybil

We need writers!

Our writers are growing up and getting older That is og course good. BUT.... it means they are leaving us Therefore: would you like towrite for us?

What is required?

That is easy You have to be in grade 10-12 Impeccable in your preferred language-and that might not be English. We try to be more than just English Passionate about your topic of choice no dull articles here

Do you get anything out of it?

Well, not money, sorrry. BUT if we publish your articles you will have: Your bio in a commercial magazine A photo of yourself You can put it all on your CV you can use us as a reference ... and it goes in your portfolio

Is it important?

YES it is.

Look what Rofhiwa said: My name is Rofhiwa and I love to write.

I think I am rather decent writer too.

I took my talent and have used it to express my thoughts on international dealings of the world which have been published in Hola MaHigh-School. It has paid off, not only is my work printed for young people in the country to read, but it also contributed to me gettng a bursary from CNBC-Africa to do my post-graduate studies. Would be a lot harder to get by if I didn’t have platform like Hola MaHigh-School.

Perhaps it is their immensity. Definitely it is the whales’ authenticity and the absolute trust they show towards us.

Whale watching is one of the Western Cape’s biggest draw cards For those of you who haven’t yet sat in a boat, or stood on land, and marvelled as a whale the size of a jumbo jet rises out of the water just in front of you, or glides past and ‘catches’ your eye, then you have yet to become obsessed with watching these gentle giants.

All said and done: ENJOY SUMMER

There are dngers out there! Don’t spoil your holidays on things you could have prevented and foreseen.

Here are a few things to look out for. All from www.realsimple.com/health/preventative-helath/summer-hazards.

Jellyfish Sting Jellyfish aren’t aggressive and don’t attack humans, but accidental contact with their tentacles can cause mild to severe reactions, depending on the type of jellyfish.

If you are stung by a jellyfish, forget the old wives’ tale about urinating on the sting— it won’t help and may actually make the pain worse, says Jay Bradley, curator of the National Aquarium in Washington, D.C. Instead, immediately flush the area with seawater (don’t use fresh water—it might exacerbate the pain) to wash away the toxins that caused the sting. (Vinegar works too, though your chances of having it at the beach are probably slim.) Once home, submerge the affected area in hot water for up to 90 minutes in order to neutralize any stinging tentacles that may be lingering.

Tentacles that are still attached can be removed carefully with tweezers.

Heat Stroke The lethal heat wave that’s plagued the U.S. this summer serves as a reminder that staying cool as the temperature climbs is serious business. Excessive heat may cause a rapid pulse and excessive sweating—a result of your body overheating and experiencing heat exhaustion—especially in people who are working or exercising outside.

Without proper hydration, heat exhaustion can escalate to heat stroke, a life-threatening condition that kills approximately 400 Americans every year.

Heat stroke occurs when the body’s internal temperature exceeds 104 degrees and is unable to cool down because the body loses its ability to sweat, says Ritucci. “The key to avoiding or preventing this condition is hydration,” he explains. “Drink plain water to replace any fluids you have lost.” On a hot day, reserve early mornings and evenings for strenuous activities such as exercising. Seeking out shade whenever possible, avoiding being outdoors at the hours of peak heat (10 a.m. to 4 p.m.), and wearing loose clothing can also help prevent overheating.

Lightning Strike Though you might put your odds of being struck by lightning at about a million to one, Stephanie Abrams, on-camera meteorologist for the Weather Channel, says

everyone has a “1-in-300,000 chance of being struck by lightning in approximately one year.” In fact, lightning is the nation’s deadliest weather phenomenon. The varying degrees of injury a lightning-strike victim might experience include burns, memory loss, personality changes, headaches, nausea, sleep disorders, ringing in the ears, paralysis, and even death.

If you’re outdoors and hear thunder, lightning is sure to follow. Seek refuge indoors or in a hard-topped car immediately: Lightning can be a threat to your safety from as much as six miles away (30 seconds from flash to bang). Don‘t think that wearing rubber-soled shoes will offer you extra protection. If you are stuck outdoors with absolutely no shelter in sight, minimalizing yourself and your point of contact with the ground may improve your odds slightly, says Abrams: “Squat down to be at the lowest point and balance on the balls of your feet to have as little connecting you to the ground.” … and this is from http://www.businessinsider.com/survive-the-summer-healthsafety-2015-6 Remember: public swimming pools are gross OK, the sunscreen is on and you’re ready to cool down. It’s time to hit the public swimming pools. There are plenty to choose from — 309,000, to be exact — and you wouldn’t be alone. Swimming is the fourth most popular sport or form of exercise in the US. But even with chlorine, swimming pools can act as giant petri dishes for bacteria like E. coli, which lives in the stomach and can cause nausea, stomach cramps, and diarrhea. The CDC analyzed 2008 data from 121,020 routine inspections and found that one in eight pools had been immediately closed for serious violations, like not having any disinfectant in the water at all.

That goes for ponds and lakes, too Freshwater lakes and rivers can also be hotbeds for viruses, bacteria, and amoebae. Last July, “70 people who swam in a lake near Portland were sickened by norovirus,” according to CBS News. Over half of them were between the ages of seven and 10. Norovirus, which is highly contagious, can cause diarrhea, stomach cramps, and vomiting.

The CDC reports that how the lake became contaminated is unknown, but suggests that if a swimmer with norovirus vomited or had “a fecal incident in the lake.” According to the report, “there is evidence that noroviruses can survive in water for several months and probably years.” [the] diagnosis is usually made after death.”

Energy Sources -

Thanks to Masizba, we have now a firm knowledge about nuclear power. I do not believe that it could have been much better. THANKS Masizba.

Let us just wrap it up a bit. Also by looking at the other energy sources.

I found this on Wiki: Classified according to the energy reserves of the energy source used and the regeneration capacity with: renewable: When the energy source used is freely regenerated in a short period and there are practically limitless reserves; An example is the solar energy that is the source of energy from the sun, or the wind used as an energy resource. Renewable energies are: solar, wind, geothermal, oceanic tidal, waterfall, etc.

nonrenewable: They are coming from energy limited sources on Earth in quantity and, therefore, are exhaustible. The non-renewable energy sources include, non-exclusively: oil, gas, coal and nuclear.

Let us be practical: The industry and modern city living require electricity.

The options right now in SA are realistically: Solar, Wind, Coal and nuclear.

However, let us not forget that rural areas still burn wood for cooking and heating. And that produces heavy pollution. It is a health risk in both rural areas as well as squatter camps. This is serious stuff and will need to be addressed sooner or later!

SA has a huge reserve of coal and it does make sense to utilise this. It is not going to run out for decades. BUT: as much as we try, coal is not green! Pollution and global warming are realities. Let us look at the two recent power stations in SA – Medupi and Kusile: Medupi When completed, the power station is to have six boilers each powering an 800 MW turbine, producing 4800 MW of power. Completion of the first two units was expected by 2012 but various delays have impacted on progress. The power station was initially expected to cost R80 billion (2007 Rands), but is now forecast to cost R154 billion.(2013 Rands). Not exactly in-expensive.

- The conclusion Kusile It is expected that Kusile would consist of six 800 megawatt coal-fired generating units for a total generating capacity of 4,800 megawatts Kusile Power Station is estimated to cost R118 billion to complete The plant is expected to emit an estimated 36.8 million tonnes of CO2-equivalent per year once it is completed.

A 2011 report “The True Cost of Coal: The monstrous price of South Africa’s coal addiction” by Greenpeace Africa and the University of Pretoria’s Business Enterprises unit calculated the full costs of the Kusile plant, from climate change to water use, and the impact on health and the environment.

It was estimated that the damage caused by Kusile will cost South Africa between R31.2 billion and R60.6 billion a year, and that just 30% of Kusile’s externality cost would be able to generate five times the coal station’s proposed power with renewable energy. Roughly 70% of the total cost was water-related.

So, yes. We have coal but it still costs a lot of money (and pollution) to use.

But nuclear?

The nuclear power industry in Western nations has a history of construction delays, cost overruns, plant cancellations, and nuclear safety issues despite significant government subsidies and support.

Former NRC member Peter Bradford and Professor Ian Lowe have recently made similar statements. However, some “nuclear cheerleaders” and lobbyists in the West continue to champion reactors, often with proposed new but largely untested designs, as a source of new power.

According to Masiziba, the ‘traditional’ reactors have a lot of set-backs.

Costs, pollution, inherent dangers, waste storage, etc. The Russian reactor designs (4th and 5th generation designs) are promising and will not have the same draw-backs. BUT (as can be seen above) are by and large untested designs.

What to do? Renewable energy then?

Who is doing that? Is it even feasible to rely on it?

Renewab In 2013, China led the world in renewable energy production, with a total capacity of 378 GW, mainly from hydroelectric and wind power. As of 2014, China leads the world in the production and use of wind power, solar photovoltaic power and smart grid technologies, generating almost as much water, wind and solar energy as all of France and Germany’s power plants combined.

China’s renewable energy sector is growing faster than its fossil fuels and nuclear power capacity. Since 2005, production of solar cells in China has expanded 100-fold. As Chinese renewable manufacturing has grown, the costs of renewable energy technologies have dropped. Innovation has helped, but the main driver of reduced costs has been market expansion.

That should re-assure us all that it is possible to have a huge amount of energy being produced outside of coal and nuclear. PS: SA’s new nuclear reactors will produce 9,6 GW. That is some 3% of China’s generation from renewables alone! … and the most convincing one of them all: Denmark!

Wind power produced the equivalent of 42.1% of Denmark’s total electricity consumption in 2015, increased from 33% in 2013, and 39% in 2014. In 2012 the Danish government adopted a plan to increase the share of electricity production from wind to 50% by 2020, and to 84% in 2035. Denmark had the 6th best energy security in the world in 2014. This is huge!

And an added benefit for Denmark: The Danish wind turbine industry is the world’s largest. Around 90% of the national output is exported, and Danish companies accounted for 38% of the world turbine market in 2003, when the industry employed some 20,000 people and had a turnover of around 3 billion euro. The Danish wind turbine industry had a turnover of DKK 84 billion in 2014 (some Rand 168 billion).

What to do? Where to go? It is YOUR future after all and your choices will be there for decades to come! Choose wisely as it is said in Harry Potter.

ble then?

Can we live óff-the-grid’? Here is an example - Denmark again. Small island: Samsø Island.

The island of Samsø erected 11 one-megawatt, land-based wind turbines in 2000, followed by ten offshore 2.3 MW wind turbines completed in 2003.

Together with other renewable energy measures, this community of 4,200 achieved fame, claiming that it is the largest carbon-neutral settlement on the planet.

This claim exploits the general discourse, that one can neglect carbon-dioxide and other pollution from fossil fuel consumption (cars, imported electricity, heating for houses...), if the yearly average electricity production from sustained sources is higher than the total energy consumed.

November mont It is sort of a funny month. Exams of course. And countdown to December and holidays and do-nothing days.

But has November got no redeeming qualities?

Well, it has. There are a couple of things going for November, of which I shall be mentioning two. I like opposites. And this is really opposite.

‘Black Friday’. You know that one from America?

The first major event is All retailers having a sale?

Black Friday is the Friday after the US Thanksgiving Day (the fourth Thursday in November). A lot of American states have declared it a national holiday. So the Americans really get Thursday and Friday off. Smart!

The ‘word’ is spreading. Black Friday is now creeping into other countries across the globe.

Germany, Canada, Mexico, The Netherlands, Denmark and so on. All in on it. Also SA of course.

We promised to mention another event. Oh yes. Here it is:

Buy-nothing Day. You didn’t expect that one? Did you? Ok, clever you.

Buy-nothing Day also falls on the Friday after Thanksgiving Day. Same as Black Friday.

However, Buy-Nothing Day was there before Black Friday. It was really a silent protest against over-consumption and was started in the 90’s. You simply cannot beat mom and dad’s activity level on these type of things. Flower-power was not in vain.

According to Wiki: “Campaigns started appearing in the United States, the United Kingdom, Israel, Austria, Germany, New Zealand, Japan, the Netherlands, France, Norway and Sweden. Participation now includes more than 65 nations” WOW!

th - The fun one But what to do? What activities?

•

•

Credit card cut up: Participants stand in a shopping mall, shopping center, or store with a pair of scissors and a poster that advertises help for people who want to put an end to mounting debt and extortionate interest rates with one simple cut.

Zombie walk: Participant “zombies” wander around shopping malls or other consumer havens with a blank stare. When asked what they are doing participants describe Buy Nothing Day. Whirl-mart: Participants silently steer their shopping carts around a shopping mall or store in a long, baffling conga line without putting anything in the carts or actually making any purchases. ... and a lot more

So, November is not boring, really.

There is only one more thing: November is also

World Toilet Day. This is se-

rious. Wiki: “It was estimated in 2015 that 2.4 billion (about 1 out of 3 people) lack access to improved sanitation facilities, and just under 1 billion continue to defecate openly.[2] Sanitation is a human right, just like the human right to water. Lack of access to sanitation, impacts on health, dignity, and safety.

Give that a thought as well. Also in South Africa!

And now to something serious for December!

Why are boys “weird”

Here is some absolutely useless piece of information for you. But you have to lean back

and reflect on it. Are you ready?

Have you ever wondered why there seems to be more boys/men as inventors? Test pilots? Rocket scientist? Nerds? Crazy? Stupid? Ever wondered why girls are not “crazy”? They don’t do “stupid” things, do they? Boring maybe.

OK, so here is an explanation.

It is in the genes all of it. Now, we know that boys have an X and a Y chromosome. And girls have 2 of those X chromosomes.

The X chromosome has 1,846 genes. The Y has 454 genes.

It was the belief that if a gene on one of the pairs was active, the other one would be inactive – like switched off. Sounds good, but not really the case. Both are active and both will influence behavior or looks or whatever we are talking about.

Look at the X chromosome. Look at one gene. If that is a gene for “crazy”, the other X chromosomes “crazy” gene might just moderate it a bit. Making it less crazy, more middle of the road. Like boring.

But if it is an X chromosome gene and it is a boy and there is no Y gene there. Then what? He just might be a bit extreme because there is nothing to moderate behavior and nothing to stop him from being “crazy”. After all, women have 1,846 times 2 genes with their X chromosomes, whereas boys have the first 1,846 genes, but only

” and girls “boring”?

454 genes to match it up with. That leaves some 1,392 un-controlled and un-moderated genes. Wow. No wonder.

Here is another piece of the puzzle. If we now look at a stupid-genius spread, girls curve will look like a perfect Poisson distribution, the lambda curve (yes, I know, statistics, big numbers, yes, yes) and boys will be more flat.

Here is one:

The perfect Because they to their 2 x X fewer “stupid” also less “Ein-

curve represents girls. are more “moderated” due chromosomes, you will find girls (left part of it) but hey, stein’s”.

Boys do not have any moderating influence (at least for 1,392 genes), hence more “stupid” and crazy boys, but also more Einstein’s.

Look around you. How many men vs women as presidents? Millionaires?

Living under the bridge? Chefs in restaurants? And also: taking care of others? Looking after the kids? Building the nest? Family centre?

It can be very chauvinistic and sexist. But it isn’t. Fact is, boys can be more all over, but girls are not crazy.

Now, that’s the truth, according to latest research. Useless piece of information, really.

Antarctica: A diff As promised, we look at a huge continent. Not Asia, not America… but Antarctica.

Antarctica is 98% covered in ice, on average some 2 km thick. But there is solid land underneath. It is huge. Twice the size of Australia. However, there are only some 135 permanent people, but some 1,000-5,000 people on a non-permanent basis (research and scientists, etc). Nobody has been born on Antarctica yet.

Because of the thick ice shield, it is rather difficult to look at what was before. But Antarctica has not always been where it is now. When Gondwana was around, Antarctica was around equator. Tropical climate!

Antarctica is actually pretty close to the tip of Chile. So the coastal regions can be ice free.

However, nobody had actually seen Antarctica before 1820. But here is a good one. There was a ‘myth’ that there would be a huge continent somewhere down South and it was proven that it should be there to ‘counter-balance’ all the lands in the Northern hemisphere.

Wonderful! There were maps produced, speculations about what type of animals would be there, inhabiting the lush forest and so on.

Maybe even some native antarcticans around?

In came Cook. The one who ‘discovered’ a good load of the world (like Australia and so on). His second voyage proved that if there was a southern continent it would be rather ‘small’ and it would be totally covered in ice! And that was that!

And now comes the big one we have all

fferent continent heard about! The race for the South Pole. Adventurers and all kind of people travelled the world ‘discovering’ all kind of things that no European had seen before (and that was the only thing which counted in those days).

Roald Amundsen from Norway set out to reach the South Pole – nearly the last frontier. He managed before a competing expedition led by Scot got there, 34 days later.

Scot and his entire expedition died in Antarctica.

Enough of this! Why is Antarctica important? Well, it regulates the weather to a large extent. And it contains 70% of all fresh water on the planet (in ice form that is). Research is heavy as global warming will have a huge impact on the world if and when the ice sheets collapse.

Holiday cruises are now a major activity and we can predict these will increase.

Antarctica: A diff The real business comes into play when we look at the usual raw materials: gold, oil, diamonds, minerals and so on.

The problem is that it is hard to determine IF it is there and if so, in what quantities. First of all, drilling through some 2 km of ice to get to the bed rock is a task all by itself. Next problem is that the ice sheets are not static. They slowly slide towards the coast. It really means that the drilling platform (sitting on top of the sheet) is slowly moving along but the well to be drilled is static.

Not a great prospect!

But how can we then ‘guess’ on this? Insofar as Antarctica was a part of Gondwana (super continent some 500 million years ago) we can see what the ‘neighbours’ at that time had. The neighbours were South America and South Africa and Australia.

What has South Africa got? Gold and diamonds. Australia? Gold and coal and iron. And so on. So by logic, Antarctica must have some rich deposits of gold and oil and all kind of things.

The problem is that it is not so easy to get to. The season is short and the temperatures across Antarctica are not conducive to human endeavours.

There are two theories for economic activity in Antarctica: Leave it alone. We will never need it This is the one that says that before we will need the resources – at a substantial high cost for exploration – other energy

fferent continent sources will be there. Like solar, fusion and others.

This will then entail that Antarctica can be left alone to the scientists and researchers.

We need to start now. The resources are needed shortly This is the one that says that we need to determine the extent of resources and at what costs we can exploit these. The danger is of course that we tip the rather delicate balance in a very fragile ecosystem. And if it is gone, it is not coming back.

Predictions: Antarctica will be settled within the next 50 years. It is the last piece of real estate and the growing world population will have nowhere else to go. It will be ranking alongside some of the ‘Sea States’ we see in science fiction books.

Happiness .. or h This is a little fun piece to write – HAPPY or HAPPINESS. Marvellous. Who does not want to be happy? Exactly.

BUT what is to be happy? What is happiness? Can we even define it?

Now here comes the fun part. It is indeed defined. Let us turn to Wiki: Happiness is a mental or emotional state of well-being defined by positive or pleasant emotions ranging from contentment to intense joy. Happy mental states may also reflect judgements by a person about their overall well-being So it is scientific after all.

The United States Declaration of Independence of 1776, written by Thomas Jefferson, says “the pursuit of happiness.” But did they mean that all Americans should walk around grinning like fools? In fact, happiness at that time (18th century) meant “prosperity, thriving, wellbeing”. Remember the movie “in pursuit of happiness”? that is the right interpretation.

Sonja Lyubomirsky concludes in her book The How of Happiness that 50 percent of a given human’s happiness level is genetically determined (based on twin studies), 10 percent is affected by life circumstances and situation, and a remaining 40 percent of happiness is subject to self-control.

This is horrible! It means that whether I am happy or not is actually pre-determined. It is in my genes., nothing I can do about it. I can only control 40%. So “don’t worry, be happy” doesn’t mean anything then.

how to be happy Ok, then. But what about money: “It has been argued that money cannot effectively “buy” much happiness unless it is used in certain ways. “Beyond the point at which people have enough to comfortably feed, clothe, and house themselves, having more money - even a lot more money makes them only a little bit happier. “ In the book Lucky Go Happy : Make Happiness Happen!, Paul van der Merwe uses a graph to illustrate that money cannot make people happy. A Harvard Business School study found that “spending money on others actually makes us happier than spending it on ourselves” Psychologist Martin Seligman asserts that happiness is not solely derived from external, momentary pleasures,[16] and provides the acronym PERMA to summarize Positive Psychology’s correlational findings: humans seem happiest when they have Pleasure (tasty food, warm baths, etc.), Engagement (or flow, the absorption of an enjoyed yet challenging activity), Relationships (social ties have turned out to be extremely reliable indicator of happiness), Meaning (a perceived quest or belonging to something bigger), and Accomplishments (having realized tangible goals).

OK, so now it is also about the entire life. This actually makes a little bit of sense.

I am happy!

Cross-sectional studies worldwide support a relationship between happiness and fruit and vegetable intake. Those eating fruits and vegetables each day have a higher likelihood of being classified as “very happy,” suggesting a strong and positive correlation between fruit and vegetable consumption and happiness.

I give up now. So, “an apple a day keeps the doctor away – subject to your aim of course”.

However, in 2015 a study building on earlier research found that happiness has no effect on mortality. Consistent results are that “apart from good health, happy people were more likely to be older, not smoke, have fewer educational qualifications, do strenuous exercise, live with a partner, do religious or group activities and sleep for eight hours a night.”

Happiness does however seem to have a protective impact on immunity.

The tendency to experience positive emotions was associated with greater resistance to colds and flu in interventional studies irrespective of other factors such as smoking, drinking, exercise, and sleep.

There you have it! Eat fruits, sleep at night, go to the gym, be boring and be happy .... and don’t worry!

Our calendar: C

If anyone should think that the calendar and the number of days and the months and those things are like ‘cast in stone’, well, think again.

The French Revolution was in many ways also a huge step forward from backward regimes. It was also an enlightened and a scientific approach to all things.

Of course the poor calendar was a target.

So, to make life easier (as the metric system had just been introduced) a day got cut into ten hours, each hour into 100 decimal minutes, and each decimal minute into 100 decimal seconds. Thus an hour was 144 conventional minutes (more than twice as long as a conventional hour), a minute was 86.4 conventional seconds (44% longer than a conventional minute), and a second was 0.864 conventional seconds (13.6% shorter than a conventional second) (source: Wiki).

That should be easy.

Now the calendar got a bit more funny. Twelve months were retained and they got depicted with roman numerals. Of course they had a new starting date: 22 September 1792, the beginning of the “Republican Era”.

The names of the months?

Autumn: Vendémiaire, “grape harvest”, Brumaire, “mist”, Fri-

maire “frost” Winter: Nivôse “snowy”, Pluviôse “rainy”, Ventôse “windy” Spring: Germinal “germination”, Floréal “flower”, Prairial “meadow” Summer: Messidor “harvest”, Thermidor “summer heat”, Fructidor “fruit” Oh yes, there were now ten days in the week.

Cast in stone?

… and that is where the wheels came off. So how many weeks should there then be in a year? After all it is not possible to get Earth to go faster (or slower) around the sun.

There will still be 365 days in a year. So how to match this into 10 days per week? And what about people’s salaries? Still paid per week? Chaos reigned supreme. So they went back to the ‘old’ system.

But didn’t we have something similar some years back? YES: Internet time Wiki says: “Swatch Internet Time (or beat time) is a decimal time concept introduced in 1998 by the Swatch corporation as part of their marketing campaign for their line of “Beat” watches.

Instead of hours and minutes, the mean solar day is divided into 1000 parts called “.beats”. Each .beat is equal to one decimal minute in the French Revolutionary decimal time system and lasts 1 minute and 26.4 seconds (86.4 seconds) in standard time. Times are notated as a 3-digit number out of 1000 after midnight. So, @248 would indicate a time 248 .beats after midnight representing 248/1000 of a day, just over 5 hours and 57 minutes” … and that did not take off either!
