[picture link] Osama's Bin Laden's Pakistani Hideaway - an ordinary everyday suburban house!

You will not believe it. The house of the world’s number one terrorist, before his death, looks like an everyday house you can find on the streets of Lagos.

It’s not his house actually; just a hideaway in Pakistan.

This series of 21 pictures on Time.com shows a man running away from the world, lost to worldly splendor but surrounded by death, destruction and disaster. A man who had seen his dying days and that of the terror organization he helped to create.

The room has an ordinary bed, common wardrobes and looks like an everyday suburban house.

One would have hoped his hideout was somewhat luxurious; with the wealthy and powerful of Pakistan. Wishful thinking!

Osama Bin Laden's Paskistan Hideaway.

[Cartoon]: Between the devil and the blue sea?

What would you do, if like Sam below, you were asked to choose between one of the two options offered?

Choices are a basic fact of life. Some choices can be a turning point in our lives while some are inconsequential and will only satisfy some ego.

Whatever choice you are making, now and in the future, judge the merits of the possible outcomes of that choice before taking the leap.

Nigerians are not that barbaric!

Take a look at the picture below. This is a horrible sight. The deed is a barbaric act. The victim concerned has accepted her fate; look at how calm and composed she appears! Justice will never come to her aid. The mob has decided on her. The mob is justice.

This is barbaric, oh Nigerians!

That is the face of Nigerian law. The rule of law has vanished. It exists only for the well-to-do. As a Nigerian, who reads the daily news, I understood that the people, our people, are scarred beyond repair, both mentally, physically and emotionally. The stories of crimes that go perpetrated without the criminals getting punished, rather the criminals become victors, is aplenty. The quest for riches and money is beyond imagination.

These and many more reasons have made people to resort to taking laws into their hands.

The rule of law can go to hell, a typical Nigerian on the street will tell you. If you cross check his stories, he’ll turn out speaking the truth.

Does it mean our society should endure mob injustices like this?

No matter the crime she must have committed, as a human, she deserves to be taken to the authorities; handed over to the police. The law should be a constraint upon human behavior and not something to be shunned because the poor and the weak are not protected since they do not have the money to fund a case.

In Nigeria, let respect for human rights be a platform we should be standing on.


The müller cells also play a role in our making sense of color and light

Do you have cataract? It is a disease of old age. Most times, cataract affects an individual due to exposure to radiation, chemicals and other environmental factors that reduce the ability of the eyes to function properly. Cataract, as a disease, is due to the lens that captures light in the eyes becoming opaque, thereby preventing light from passing through to the photoreceptor cells at the retina.

I wrote an article this week on the dress that caused a sensation on social media circles because of the difficulty it imposes on a viewer as to light perception. Persons who suffer visual problems like cataract do not enjoy and revel in the sensation of light and color as others. French impressionist, Claude Monet, is in that class. Her visual problems made her paintings imprecise and muted in colors. If you suffer from visual problems, you have to cope with inefficient light reception.

Is it white and gold, or blue and black?

Apart from the cones and the rods in the retina which distinguishes daylight from night vision, there is another group of cells in front of the retina which work towards our enjoying color.

Those cells are called Müller cells or müller glia. These cells function as light and color filters. Their position in front of the retina makes sure that the light getting to the rods and cones are already sorted, filtered and organized. Clever, not so?

Müller cells, according to Dr Erez Ribak from Technion, the Israel Institute of Technology, are at just the “the right height, and their light-bearing trunks are just the right width, to filter the wavelengths correctly”.

So, as you look at the dress again, and if you wonder why so many persons disagree on what color they perceive, you could place the müller cells as one of the candidates at the heart of their visual problems, if not a disease like cataract.

Soon, an end to gang wars with guns and rifles; here comes the fiber optics laser.

In the nineteenth century, there were many prodigious inventors. One of them believed in inventing weapons of warfare and wanted them for pacifist uses. He was Alfred Nobel (21 October 1833 – 10 December 1896), nicknamed “the merchant of death” in an obituary published in error. I wonder if he would turn in his grave if he were to witness the power packed in directed-energy weapons, or weapons of warfare that use light and electromagnetic radiation to produce their powerful devastating impact. Some call them laser weapons.

It is no longer news that laser weapons are now commonplace in military research. What makes news is when they are made deadlier, more portable, more efficient and more affordable.

Introducing ATHENA (Advanced Test High Energy Asset), a directed energy prototype, developed by Lockheed Martin; a 30 kilowatt single-mode fiber weapon system. From a distance of a mile (1.6km) it reduced the engine of a car to flames.

Imagine the power packed behind the ATHENA fiber optic laser system!

A mile is just a distance for the prototype. ATHENA can go farther and its uses can go furthest, even beyond the military.

The potentialities for such portable weapons is beyond the imagination. Sci-fi and Dr. Who will be shows of the past. Welcome to the real world. The same way guns replaced knives and arrows, these weapons could be the weapons of the streets of the future.


I wonder if the demand for personal locator beacons are rising?

It’s sad. 365 days after the disappearance of Malaysia airlines flight MH370, the report that was recently published offered no satisfactory answers. The locator beacon without a battery was a false hope indeed.

The emotion was touching. The sadness could be felt even when the victims were not related to you.

One of the posters, “Dad I miss you,” stirred a nerve in me.

In Nigeria, the Chibok girls abducted on April 14, 2014 have not yet been found. The President, Goodluck Jonathan, made a promise recently that the girls were safe. At the approach of another anniversary for dearly beloved missing persons, we could be faced with another false hope? Maybe, maybe not! I’d place my cards on the maybe.

If I was taking a trek to the mountains, going scuba diving, or visiting Northern Nigeria, I’d be wise to take along a personal locator beacon. Did you know locator beacons could also be fitted to one’s person?

I searched on Google and found some myself. Like this site that offers personal locator beacons for rent. I was wondering: maybe the demand for locator beacons should be on the rise!

[Cartoon]: How do you mix business with friendship?

A friend once told me: “I’d rather an enemy I know than a friend whom I don’t trust.” Not the actual words but something along those principles.

Losing my teaching job a week ago, I thought up this cartoon on the way from an interview.

I still haven’t gone over the lose because I thought I was doing my best and didn’t deserve it.

Maybe I shouldn’t; I shouldn’t have been working the extra mile.

Maybe!

What I call white and gold, you might call black and blue. Why?

The brain perceives color when light falls on the retina and interprets these colors by sending the light, as electrochemical signals, to the brain. The rods perceive night vision while the cones at the retina perceive color. It’s not so simple as that because vision involves more than just perceiving darkness and color.

It includes, as this BrainHQ.com article describes it, distilling foreground from background, recognizing objects in various orientations and accurately interpreting spatial cues.

A dress was recently posted on tumblr.com (click to see it yourself), the social networking site, and the question was: what is the color of the dress? Is it white and gold, or blue and black?

The question brings up the concept of how the brain interprets color. At least, the following factors determine how your brain interprets colors so you do not go about thinking you must have an eye problem.

  1. Time of the day, whether during the day, when the cones are at work, or the night, when the rods are more at work.
  2. Surrounding light conditions or illumination.
  3. Distance between the eyes and the object or dress, in this case.
  4. Medium of perception: air, monitor, cellphone screen or TV screen.
  5. Stored memory of past experiences and interpretations.
You can find these explained on abcnews.go.com.

Actually, the dress is not white and gold, but shades of black and blue. The brain at work tweaks colors in varied ways that no color stays true throughout the day.

Stop! Stop stereotyping boys and girls.

A good teacher should be quick to recognize the fact that gender stereotypes exist. I personally can attest to that being a teacher myself; though presently out of favor.

A recent OECD study, reported by the BBC, has shed more light on that fact.

I can prove it! I'm smarter.

If we tend to label boys as stupid and girls as cleverer, the answer does not lie in the gene. It lies in us, the adults and how we have structured the society. The answer lies in the self-confidence we have imbibed in these young adults as teachers, parents and guardians of their psycho-social, moral and intellectual capabilities.

The answer lies in parental and educational expectations we place on them. These expectations have created a gender inequality in education in Africa because most parents believe girls are good only in the kitchen and for giving birth to babies, so what uses wasting hard-earned money investing in them?

The answer lies in our cultural biases; as noted also above. How many girls are taught leadership education? A girl would be scoffed at if her aim is to be the President of the country in the future.

It is also found in the school system. How are the curriculum developed? What is the aim of policy, educational programs and teacher professional development programs in our schools?

Let’s start making these issues straight before labeling those young adults as clever, stupid, dull, smart, brilliant etc, especially writing gender labels that won’t wipe away easily.


History of distance education on Infographics

I have been busy last week and this doing teaching development practice. On the course, Foundations of Virtual Instruction by the University of California, Irvine, on Coursera.org's MOOC. I found this informative infographic on the history of distance education. I just had to share with you. You can pass it on.
