How to Assess IMPACT on Your Audience

Recently I have been working with small devising companies to explore how they can obtain meaningful and accurate data to assess audience impact. I am going to give you three scenarios of their process of evaluating impact, and then how they re-worked this data gathering the second time they performed. The first performance was a ‘soft’ sharing or rather a ‘work in progress’, which is common practice for many devising companies, so they can evaluate their work before it is ...

An Introduction to Equilibria

Equilibria can be a tricky concept to understand. In order to understand it, you need a good idea of reversible reactions and then a good idea of a dynamic equilibria. So, what is a reversible reaction? Put simply, it is a reaction in which products can be turned into reactants, but reactants can also be turned back into products. This can be shown using the ⇌ symbol: Reactants ⇌ Products For example, ammonium chloride will thermally decompose into ammonia and hydrogen chloride gases, but these gases will ...

What’s the difference between an expression and an equation?

Well, I’ll answer that in a moment. More generally, you should be familiar with algebraic terminology since relevant words are used in exam questions—you need to know exactly what they mean. Let’s start at the beginning and build up… Constants and variables A constant is a fixed number, such as 2. A variable is a letter which can take on different values, such as $x$. To complicate things, letters can sometimes be used to stand for constants! For example, I can define ...

Oligarchy and Democracy in Plato’s Republic (Part 1)

In Books VIII and IX of The Republic, dedicated to imperfect societies, Socrates undertakes a systematic political and psychological survey of the forms of government following the demise of his perfect state, doomed to extinction like all human creations. It is gradually replaced by a new regime, inspired by Sparta’s principles of ‘honour’ and ‘worth’ (or ‘time’ in Ancient Greek), in which war becomes the main preoccupation of rulers chosen among ‘the simpler, hearty types’ instead of the intelligent Guardians ...

Electric Vehicles in China

China wants to lead the world in the manufacture and use of clean-energy cars, and to achieve this it will need to ensure research and development in battery production. Batteries have become vital to the manufacture of clean energy cars. As part of China’s industry development plan (April 2017), the government pledged to promote research and development of key battery cell parts and improve management structures in the industry. Batteries are at the heart of clean energy vehicles because they are ...

. . .and more about syntax

The more we think about syntax, reading or writing it, the more we close in on sentences. If syntax is basically the ordering of words, sentences are how we deliver or read that ordering of words. We can opt for doing this in staccato ways with punchy short sentences, in long leisurely orderings, or in sentences that withhold a crucial element until the very end. And good writers use all of these. It’s relevant, then, to do a quick review of ...

Happy Anniversary – or when is Wednesday?

Soviet-era propaganda poster On October 25 1917 the Bolsheviks seized power in Petrograd, beginning the process of Communist control in what would become the Union of Soviet Socialist Republics.  Based on that information alone, most would think that we are currently marking the centennial of the revolution, but. we aren't really. As students of Russian history know, the Tsars followed the Julian calendar while most of Europe followed (and continue to follow) the Gregorian calendar.  The change was evolutionary in nature, ...

Animating Still Life

I hope you remember reading a post of mine which was published on this site at the end of July this year titled Transforming the meaning of evidence and truth. If not, go have a look, and then watch this video, and read on below. https://www.youtube.com/watch?30=&v=-RetOjL1Fhw "What use is there for this technology, you may be asking? Well, with Facebook’s involvement, it is quite possible that users will be able to animate their profile picture and cause it to react to stimuli ...

Muhabbat Sharapova, Mathematician – and Hero of Uzbekistan

To be named as a "Hero of Uzbekistan" is to be awarded the highest national honour in that country. Recently, Muhabbat Sharapova, one of the country's top mathematicians, received the award - not for her mathematical prowess, but because she has turned down job offers from many leading universities and institutions in favour of remaining a maths teacher in her small home town. In an interview for the BBC's 100 women initiative, she says: "Mathematics is the mother of all sciences." ...

LANGUAGE vs SENSE PERCEPTION (Art and the Theory of Knowledge)

A picture - worth a thousand words? My visual arts blog this month has a Theory of Knowledge element. I’m in the happy position of teaching both DP Visual Arts and DP Theory of Knowledge. There is a lot of Art/TOK overlap, but one activity that I recently had with ToK and Visual Arts students was very much in the ToK mode of questions... Sight and Sound (The limits of language) The ToK starting point was a discussion of Ways of Knowing: how do ...
