Dalai Lama

Although violence and the use of force may appear powerful and decisive, their benefits are short-lived. Violence can never bring a lasting and long term resolution to any problem, because it is unpredictable and for every problem it seems to solve, others are created. On the other hand, truth remains constant and will ultimately prevail.

The 14th Dalai Lama (6 July 1935 -)

Project X – Party & Peer Pressure = Bad Decisions

Yesterday I came across a news article on the death of a boy in Houston. The boy was shot multiple times and died as a result of the injuries sustained. He was one of many hundred partygoers, who had gathered in a mansion to celebrate spring break in “Project X” style. What does celebrating “Project X” style mean? It means that first you are no longer a teenager and second it is the title of a Hollywood movie released this year.

Naturally I went to IMDB to watch trailers of the movie and read up on what it was about. It actually sounds like just another teen movie, where a kid throws a birthday party at his house when his parents are out for the evening. He and his 2 friends plan on becoming popular at school because of the party. As expected lots of people turn up and the party gets out of control; things go up in flames, a person of very small stature climbs out of the oven and starts punching them in the sensitive area between their legs. In one scene, a neighbour even gets tasered when he threatens to call the cops because of the noise. This plot is not something new. I am assuming the only difference to the movies before lies in the magnitude of destruction. Lots of things are destroyed for one night of carefree fun.

Is the movie to be blamed for these teenagers’ destructive actions? Ever since it has become possible to “invite” strangers to a party via Twitter or Facebook, such parties have taken place all over the world. The teenagers simply have a cool name for their parties now. You have to admit that “Project X” sounds catchy. Teenagers have always wanted to party through the night. Flirting with the other sex probably causes the adrenalin level in the body to sky rocket. If alcohol is available, I shudder at the damage teenagers under its influence could cause. Yes, the movie is to be blamed for giving an impressionable group of teenagers ideas for such parties. No, the movie is not to be blamed because it can also be seen as portraying the vulnerable nature of teenagers and their need to belong to the “cool” group. These teenagers would have partied just as wildly and carried weapons around, even if the movie was never made.

I read an interesting article which explores the connection between age and peer influence. This article talks about a test carried out on three age groups; teenagers, young adults and adults. The aim was to discover how peer pressure influences one’s willingness to take risks. The test takers played a race on a computer. The aim was to finish the race with the quickest time possible. They had the option to stop at yellow lights, which would cause a slight delay. However the probability of maintaining control of the vehicle is high. Alternatively they could pass yellow lights without stopping. As a result, they risk driving too fast and crashing the vehicle, which would result in a longer delay. They went through this test twice. During the second run, they were told that their (same-sex) friends were watching the test from the room next door.

The teenagers were the only ones, who altered their behaviours. Physically the part of the brain that has to do with rewards became active, when they thought their friends were watching them. It is seen as the reason for their reckless behaviour in the second round. Interestingly peer pressure doesn’t only occur, when friends are bodily present. Simply the thought of friends being aware of what one does is enough to influence a teenager’s action. The scientists believe that this could provide the reason why a child, who is mature in the presence of his parents, could still act irresponsibly when with his friends.

This reminds me of some incidents in Germany, where kids beat up complete strangers in the public. They acted in groups and not all regretted what they had done. This apparent callousness frightens me. Is it futile to hope that teenagers behave sensibly even in the company of their friends? But there are still some well-behaved teenagers in this world, right? What causes them to behave well? Well-behaved friends? Something else? Do you have teenage kids? What is your experience?

A simple idea led to free education for all

I watched another TED video by Adam Savage. You know the guy from Myth Buster; not the one in the beret, the other one. He was talking about how simple ideas have led to profound scientific discoveries. Do you know how Eratosthenes’ calculated the Earth’s circumference without the help of powerful computers? Do you know how Hippolyte Fizeau measured the speed of light using a toothed wheel, a light source and a mirror? This informative video is 7:32 minutes long and holds the answers to these questions. I would encourage you to watch it. Basically Adam’s message is that by only using our senses and minds we can come up with simple ideas to make the world a better place.

Do you believe in coincidences? Or do you believe somehow everything that happens is meant to happen that way. Either way on the same day I came across another interesting video of the CBS news show 60 Minutes. The title of the show was “Khan Academy: The future of education?” The video portrayed how a simple idea is revolutionising education and the role of teachers worldwide.

Who is behind Khan Academy?


Sal Kahn has 3 degrees from MIT and an MBA from Havard Business School. He started his career as a hedge fund analyst. He did not have a sudden vision to provide free education to all. In fact it started out as a simple idea to help his cousin, who was struggling with Mathematics in school. Since she did not live nearby, he decided to tutor her over the internet. Later when other relatives and friends approached him for his tutorials, he decided to post them on YouTube. This was when he discovered the real demand for the kind of tutorials he was producing. In 2009 he decided to quit his job and pursue a fulltime career producing tutorial videos for his YouTube channel.

In 2010 Bill Gates revealed in an interview that his children were learning using the tutorials on Khan Academy. Later with his financial support, Sal Kahn was able to make Khan Academy even bigger. There is a new platform to host the videos and he has employees, working on continually improving Khan Academy. It is still a non-profit organisation and is dependent on the goodwill of others to donate or volunteer to translate the videos into other languages.

To being with I am really impressed by the simplicity of his idea and how he has been able to help numerous students all over the world with it. I watched a couple of videos on algebra to judge for myself, why his tutorial style is widely appreciated. I have to say that had I seen these videos when I was in secondary school, I would not have failed my math exams. He explains the sense behind a topic, something I had missed in school.

How is Khan Academy revolutionising the world of education?
For starters, there are a couple of schools in America, which are testing out a new teaching model in collaboration with Khan Academy. Students are expected to go through the tutorials on a particular topic at home. The following day, students solve exercises on this topic in the classroom. The teacher can track real time how the students are progressing, how fast they complete a task and who is having problems. The teacher can then focus on helping those who require assistance. In other words, the learning takes place at home and the homework is done at school. The role of the teacher is more of mentor and coach.

Furthermore Khan Academy helps students from poor families, who can’t afford a private tutor, or families where the parents are not able to help with their homework. The child can learn at his or her own phase by repeatedly learning a lesson as often as required. If the child still does not understand the topic, the teacher is there to help the following day.

Even adults can benefit from Khan Academy. They can refresh their memories on a certain topic to help their children with schoolwork. It could help those, who dropped out of school, to possibly finish school and improve their academic qualifications. As a result, they could have better careers.

In conclusion, Khan Academy shows how it is possible to tremendously help others with little effort. I am sure that Khan Academy has the potential to help millions of children and even adults all over the world.

The Cloud Beckons

This post is about Cloud Computing as understood by me, a nonspecialist in technology. A few days ago the CeBit, one of the world’s leading ICT trade fair, was held in Hanover, Germany. During this week, one of the trending topics was Cloud Computing. Then on the TED website, I came across a feature on a company called Akamai, which provides platforms for Cloud Computing. The signs were there, urging me on to write about it. Therefore here I am writing a post about this super-duper what-ever-it-is.

If Cloud Computing conjured an image of a computer in the clouds turning water into food, I have to disappoint you. No, it has nothing to do with resolving world hunger ala “Cloudy with a chance of meatballs”. That would have been pretty cool. However Akamai claims that Cloud Computing would help fight against global warming. How you ask? To find an answer to that we need to define Cloud Computing.

What is Cloud Computing?

There is no single definition of Cloud Computing and so the following explanation is my personal understanding of it. In essence Cloud Computing refers to sharing server capacity by numerous users and/or organisations around the world. A suitable metaphor I can think of is a safe. You can either store your valuables in a safe at home or you can store them in a bank vault or you can use both to satisfy your need to protect your valuables. Storing at a bank has the added advantage, that there is someone looking after your property all the time and they probably have more resources to protect your property than you might have at hand and you don’t have to buy an expensive safe.

However Cloud Computing is not restricted to sharing hardware only. There are services offering licensed software for the users in their clouds. Therefore instead of buying x number of licenses, which at times might be restricted to use in specific devices, you can make use of a software via the Cloud regardless of the device you are using.

How does Cloud Computing support sustainability?

Carbon footprint has become a household term. When you book a flight, you pay a fee to offset your carbon footprint. When you order a package to be delivered to your house, you pay a fee to offset the gases emitted by the delivery van. You cycle to work and walk to the grocery shop. Your conscience is clean. Maybe you should think again. Do you know how much electricity you consume each day? Laptops, iPads & co., mobile phones all need energy to operate. Do you have any idea what your personal carbon footprint in this area is like? I have to admit I don’t but it probably accumulates to a substantial amount in my lifetime.

Companies are all into sustainability nowadays. Cloud Computing helps you be green and at the same time reduce costs. Have you ever been inside the server room of your company? The rooms are usually cool to prevent the hardware from overheating and there are lots of blinking lights, even when no one is in the office working. Therefore there is energy consumption without corresponding productivity or in other words value creation. By joining the Cloud, you are basically outsourcing these servers. You no longer have hardware taking up valuable office space and consuming energy even when they are idle. You store all your information in the Cloud.

Now those offering Cloud Computing platforms do have hardware, with all the associated non-green aspects mentioned earlier. Is the concept really green? The key point is by serving a wider user base, the Cloud can effectively reduce idle time and utilise the server capacity available. Therefore instead of 500 000 thousand servers being used by various organisations, the Cloud only needs about 40 000 servers to do the same amount of work. (These numbers were cited by Akamai in a promotional video.)

How does Cloud Computing impact you?

Chances are you have already had contact with the Cloud in some form. You are simply not aware of it. Akamai alone has some reputable customers and there are so many other providers of Cloud Computing on the market.

Have you ever lost a work laptop? You lose more than the presentation you were working on. There are usually sensitive company data stored in the hard-drive. Data and information equals to money and competitive advantage in today’s world. If you were using the cloud, no data would be stored locally and ergo no data lost and no breach in security to fear.

Security leads me back to the metaphor of bank vaults. It is common knowledge that valuables are stored in bank vaults. Therefore they are often the target of criminals, who want to get rich quick by getting possession of these valuables. Likewise the Cloud might become a target for hackers and if you are unlucky, they might find a way to get hold of your data. By storing data in the Cloud, you are solely dependent on the Cloud to protect it for you.

My Conclusion

Every cloud has a silver lining. But clouds could cause floods too. As a private individual, I would probably buy an external hard drive to store my personal data; like photos. As it is Facebook and Google know way too much about me, I don’t need to add the Cloud to that list too. I shiver at the thought of what would happen, if they all joined forces. 🙂 That is my view on Cloud Computing.

Neglected by evolution or man’s own doing?

What do the following biblical characters have in common apart from the fact that their related by blood; Adam, Seth, Enosh, Kenan, Mahalalel, Jared, Enoch, Methuselah, Lamech and Noah? They are also known as the Antediluvian Patriarchs, which translates as Scriptural Fathers of the Pre-Flood Age. According to the bible, they all lived to be a couple of hundred years old. That was my first thought when I read the synopsis of a TED talk under the theme; “Might you live a great deal longer?”

This is the final post on an unintentional series about ageing. I have written about immortality, the youth culture and the final act. Today’s post looks at Aubrey de Grey’s assertion that the first human beings to live to a 1000 years have already been born. The British researcher on gerontology claims that we need to develop treatments that repair the damage caused by ageing and thereby delaying pathology. Below you will find the video of his TED talk. However be warned that he talks really fast and packs a whole lot of information into 18 minutes.

Basically Aubrey claims that ageing leads to pathology because of physical damages accumulating in our body. He identifies 7 areas where this damage occurs; Cell loss/atrophy, Death-resistant cell, Nuclear Mutations and Epimutations, Mt DNA mutations, Protein crosslinks, Junk inside cells and Junk outside cells. (These points were listed on a slide Aubrey used during the talk – 16th minute.) I need an encyclopaedia to make sense of some of these points. But the gist of it is metabolism damages our cellular structures, which culminates in death.

Aubrey proposes that it is possible to repair the damage through treatments. He says that anti-ageing treatments would keep improving and treat people before they enter the certain death phase and thereby increasing their life duration century by century. As a result of these continuous treatment improvements it would be possible to reach a life span of a thousand years. However we need to invest in the research of such treatments immediately, if we want to experience longevity to this extent.

In the Q&A session after the talk, Aubrey stressed that ageing is not the result of selection. In his opinion, evolution has neglected to find a way to resolve mortality because it would require too much energy and more sophisticated genes. In other words, if evolution were more hardworking we probably would be immortals by now.

This brings me back to the topic of the Antediluvian Patriarchs. I probably would get to hear that the bible is a fictional work and thus not a fitting reference when trying to find answers to a scientific question. Since this is my post, we will stick to the assumption that the Antediluvian Patriarchs had existed. The last of this group, Noah, supposedly lived up to 950 years. Therefore according to the bible, men started out with life spans of almost 1000 years. However after Noah, the life span continually decreased until King Solomon only lived to be about 70 years old. According to WHO statistics from the year 2009 the median life expectancy is at 71 years. It would seem that human life expectancy has been constant for thousands of years.

Why has the time we spend on earth shortened after Noah? It would appear that sin and men distancing themselves from God led to a drastic cleansing through the flood. Noah was the chosen one to start a new civilisation on earth. However this new world became tainted by sin too.

Since I believe in the existence of God, I do not find it too farfetched to assume that God’s original creation had very sophisticated genes. However the quality of genes deteriorated overtime as a result of our indulgence in activities harmful to our physical wellbeing. Therefore I think it is plausible to undo these damages through advanced medical treatments.

Do I think this is the right time to invest in such medical treatments? No. In my opinion, if such treatments were available now, it would only benefit the rich. After all, we have vaccinations for diseases that still kill thousands of children in the third world country. The reason for their death is lack of money, which bars their access to the medication. Thus you can imagine how it would be, if it were possible to live for centuries. It would be naive to assume that such treatments would be free of charge.

What do you think?
