Science education for immortal cyborgs

David Geelan

We cannot know the future The future will surprise us somehow

– whether it be a new technology we didn’t expect that gives us unlimited cheap energy or faster than light travel, contact with extraterrestrial intelligence, an asteroid that wipes out a country and takes down the world economy, or a new super-disease

(School) Science won’t do it The science we teach in school really

only reaches the end of the 19th century

Most of the maths we teach in school is thousands of years old – the newer bits are a couple of hundred years old

What has been changing human life, and will probably continue to do so, is technology

Science & Technology

‘Science’ comes from the Greek word ‘scientia’, meaning ‘knowledge’ – science is about generating knowledge

‘Technology’ comes from the Greek word ‘tekne’, meaning ‘making’ – technology is about making stuff

They have a dynamic and stormy on-going romance

Technologies of the Body

The crucial change that is most visible right now (remembering that the future will surprise us) is the movement of technology across the barrier into the human body and mind

These technologies are the ones that will challenge our existing assumptions the most

Technologies of the Body

Life Extension

During this century, average life expectancy in most Western countries increased by 30 years, from mid-40s to mid-70s

Currently, the rate of life extension is around 2 years per decade – a year for every five years – and increasing

If the rate of life extension were ever to reach one year per year, humans would be effectively immortal

Inequities in Technology

This is the case in Western industrialised countries, but not in much of the rest of the world. In large parts of the Southern Hemisphere average life expectancies are below 55 years

The same applies to all of the other technologies of the body

Europe and Africa

Asia-Pacific

Inequities in Technology

Westerners already use far more of the world’s scarce resources – energy, water and land – than those in other countries, and have more impact on pollution, including climate change. If life extension technologies mean that their numbers increase as a proportion of world population, this is a more serious problem than population growth elsewhere in the world

Purposes of Science Education Given that these technologies (as

well as surprises) have the potential to radically change the societies in which our students will grow up, and that they will be the ones who have to decide what to do about them, and live with the consequences, what is the role of science and math education in preparing them?

Purposes of Science Education Science and mathematics education

currently seems to have two main purposes, which are often seen as being in opposition: ‘science literacy and numeracy for all’ –

equipping every student in our schools with the scientific and mathematical ways of knowing as important tools for making social and personal decisions

Purposes of Science Education

Training – and perhaps more pervasively, sorting out – those who will become future professionals in science and mathematics

I would argue that these are complementary (at least as far as training future professionals goes: we need to figure out something better for sorting, or stop doing it) rather than in competition, but that the former purpose is crucial, and we’re not making it yet

Science Education for the Future To some extent, you and I will be involved

in the social decision-making about these technologies during the next 20 years

But it’s really our students – those in school now and in the next few years – who will both influence and be influenced by the technologies of the body

Our job is to do the best job we can of preparing them
