This section of the option now has significant personal significance for me. At the end of November 2018, I was diagnosed with diabetes. Initially, this came as something of a shock to me. I eat a healthy diet, don’t drink too much and am not overweight (I have a relatively healthy BMI of 23.6). Naturally, the doctors and hospital staff wanted to find out more. There are two types of diabetes, imaginatively titled type 1 and type 2. In simple terms, ...

Card tricks fall into several categories, and my favourite are those which look amazing but actually have some pretty simple maths behind them. Here's one of the simplest! 1.     Take an ordinary pack of cards and shuffle it. Deal out 26 cards, face up, and remember the 7th card. 2.    When you've dealt out the 26 cards, pick up the pile and turn them face down on the table, to one side. (If you're brave, shuffle them first, but make ...

It's February, and grade 10 students in my school are starting to consider and possibly start selecting the subjects they would like to study in grade 11 as part of their Diploma Programme courses. My school is a ‘full’ IB school: we offer all four IB Programmes: CP, PYP, MYP and DP. Occasionally one or two students start grade 11 just taking three or four subjects with the ‘certificates only’ option, but everyone else takes the full Diploma – six subjects plus ...

The global total fertility rate (the average number of children born to a woman during her reproductive life, at present rates) is now 2.4. According to Sarah Harper, former director of the Royal Institution, falling fertility is to be encouraged. She believes that artificial intelligence, automation (mechanisation) and a healthier, older population reduces the need for a large workforce for economic growth. In a post-industrial country (and even in industrial countries) machines do much of the work that manual labour used ...

OK, I confess: my favourite philosophy book of 2018 was actually published in 2016 and it is American Philosophy: A Love Story, published by Farrar, Straus and Giroux. In his remarkably riveting enquiry into the ‘zeitgeist’ of early twentieth-century American academe, John Kaag recreates the confident and life-affirming philosophy of William Ernest Hocking, a neglected thinker overshadowed by his mentor Josiah Royce and by William James whose Principles of Psychology prompted Hocking to study philosophy at Harvard. Kaag mixes erudition and ...

At the Katowice Climate Change Conference, December 2018, member countries agreed the ‘rulebook’ for implementing the 2015 Paris Agreement into practice – in particular how emissions would be measured and progress in reducing emissions tracked. However, the Conference did not tackle the question of how countries would increase their targets to reduce emissions of greenhouse gases. By 2020, countries must show how they have met the targets that they set back in 2008. Carbon emissions appear to be on the ...

There are two situations in your Language and Literature courses where you are asked to deliver your ideas in essays: one kind of essay will let you plan, revise and present your work.  The other essay will be written under timed examination conditions. And, during your two years, you will, of course, be writing both kinds of essays.  Actually, writing a good essay is something all of us who care about writing work to master throughout our lives.  So now's ...

The Brumadinho landslide occurred on 26 January 2019 in the Brazilian state of Minas Gerais. To date, around 60 bodies have been recovered from the Brumadinho landslide but almost 300 are still missing. Although bodies were recovered it proved very difficult to identify them. The current disaster happened just three years after the collapse of another tailings (waste materials) dam, near the town of Mariana, also in the state of Minas Gerais. It killed 19 people, forced many people to ...

Chicago has been affected by temperatures as low as -30°C in January this year. When the wind chill is added to this, it was said to feel like -50°C. The reason behind these unseasonally low temperatures is the polar vortex. The polar vortex refers to upper level winds which normally keep very cold winds in the region around the North Pole. (It is a winter equivalent to the mid-latitude jet stream which sometimes breaks down forming a blocking anticyclone that ...
