The Knimbies who say No

Basic Maths- The Exponential Function

Recommended Posts

Might seem a bit odd, but this is an excellent, straightforward introduction to this function which has the most profound consequences when used in the everyday world. The lecturer is Albert Bartlett, professor at University of Boulder Colorado.

Leads into examples from the media, industry and Government, in particular with reference to population growth and natural resource consumption, and are used to illustrate the lecturer's central premises that:

"The biggest failing of the human race is it's inability to understand the exponential function" and

"There is no such thing as sustainable growth of consumption of natural resources"

The video is in 9 parts, but is a surprisingly engaging watch. It is suitable for beginners and more advanced people alike.

(part 1/9)

Enjoy. I should say don't be put off by the silly title of the youtube entry.

love the fact 5% growth over 70 years multiplies by a factor of 32! It should be easy to pay off my mortgage!

I wonder if this is why the government's insistence on providing overseas aid gives everyone a nice warm cosy glow but it ultimately a futile act.

In one way it is heartening to know that £10 compounded over 70 years at 5% growth would provide a nest egg of £320. However in reality inflation over same period means that £10 in 1941 should now be worth £410.80. On purchasing parity you are down £90.80 Linky

Some interesting stats from the 1950's to 2007 based on anecdotal evidenceLinky

In 1950 it would take 164 weeks to buy a house (just over 3 years).....In 2007 it will take 495 weeks (over 9 and a half years)

In 1950 it would take 96 weeks to buy a car.....In 2007 it will take 37 weeks

In 1950 you could buy 43 packs of ciggys.....In 2007 you can buy 48 packs

In 1950 you could buy 40 gallons of petrol.....In 2007 you can buy 61 gallons of unleaded

In 1950 you could buy 31 cinema tickets.....In 2007 you can visit 49 times

In 1950 you could buy 122 Mars Bars.....In 2007 you can buy 747 bars

In 1950 you could buy 76 pints of beer.....In 2007 you can buy 107 pints

So, has population been growing exponentially?

The rate of growth has slowed somewhat from high rates seen in parts of the last century, but yes it can be modelled with an exponential over a given timeframe. The key thing is that the population is still increasing, which is a disaster in the making.

I've seen this lecture quite a few times in recent years.

I think it should be compulsory viewing for schoolkids.

With a few blips it's being growing for centuries. The exponential part means that the effects of the growth hit you before you're ready for them. Ditto with resource consumption.
