Talk from Ben Craven - 11.02.2016
Maths is fun. Said no one. Ever. Well this is perhaps what my past narrow minded self thought in my naive high school years. I remember the main question we used to ask ourselves when sitting at the back of the boring maths class was âWhen on earth are we going to use algebra in our lives?!â
Well, our session from Ben Craven woke me up and reminded me of the importance and fun element of maths. Maths is very important from a designers point of view: having figures to back up your design is a necessity. At class in art school we are all perhaps guilty of making sweeping statements about the mathematical relevance of our design, without doing the actual calculations to work it out.Â
Not only did this session highlight the importance of figures to back up your designs but also it amazed me that you can do calculations about absolutely anything! This got me excited. Maths feeds our curiosity and also puts things into perspective. In the session we did a calculation on âHow far could you drive a car for the energy equivalent of heating the water for a cup of tea?â We derived the answer of 60m, but what does this really mean? : The energy you use to drive 60m in a car is equivalent to that of boiling water for a cup of tea. Are you shocked? Is this an answer you expected? What emotion does this answer make you feel?
I think maths does have an emotional influence and the ability to shock by putting scenarios into perspective. With regards to the cup of tea calculation it shifts your perspective on the situation. We are constantly reminded to only boil the kettle with enough water that you exactly need and to be conscious of the amount we boil - yaâ know like its a BIG deal. But when put into comparison we are never ever consider that driving an extra 60m in our car uses just as much energy... 60m is not far at all. So surely, the BIG deal should be about how far we drive as opposed to how much tea we drink?
The potential to create mathematical problems (however bizarre!) is endless. Maths allows us to be creatively curious about anything. Just with a bit of simple maths we can find out anything - which is a fun thought! I have a collection of unanswered questions Iâve imagined whilst spending many hours day dreaming in our PDE studio and I thought I would attempt to answer some of them...
How many bananas will it take to fill the Reid building?
I mean good question, theres plently of big white spaces in the Reid building lets see its potential to fill up with bananaes. Initially I estimated the dimensions of the Reid building to be 60mx25mx30m, which gave me a volume of 45000 m3. I then measured a banana and got rough dimensions of 0.2mx0.05mx0.05m, then I calculated the volume of a banana by assuming it was a cylinder. The volume of a cylinder is found by V=Ďr ²h which came to 0.0392m3. By simply dividing the volumes I came to the solutions of 1147959 bananas
It would take 1147959 bananas to fill the Reid building. (Crazy! thats a lot of bananas!)
How many head to toe Hughs can fit around the planet earth?
After a quick google I found the earths circumference to be 40075km. After a long discussion with the PDE class we can to the conclusion Hugh is 5âł10 (sorry if this is wrong!) which in meters is 1.8288m. Putting them both in the same units and doing a simple division the answer was obtained.
It will take 21913276 head to toe Hughs to go around the planet earth. (Woah, imagine that many hughs!)
How much would it cost to make our PDE class out of Halloumi?
Iâm not going to lie this calculation was around lunch time when I was dreaming of halloumi chips waiting for me down in the Vic. This calculation also shocked me the most. If we seriously wanted to do this we would definitely need to consider scaling us down...
So Iâm talking life size halloumi models. Our class consists of 7 girls and 5 boys. So with using the average weight of girls at 70kg and average of boys at 80kg and with the density of a human at 985kg/m I calculated the volume of our class. Then with these volumes and a density of halloumi of 1090kg/m I found the total mass needed to be 984.33kg. If we were perchasing the halloumi for Sainsburys then it would cost ÂŁ8.80/kg...
It would cost ÂŁ8668 to make our class out of halloumi. (How big is our degree show budget..?)
How many pints of Tennents can be pulled in the time it takes to walk from The Univerisity of Glasgow to The Glasgow School of Art?
According to Google maps the two establishments are exactly 1.0miles apart. And the average person walks at a pace of 3.1mph - so with a simple v=d/t I worked out it takes 19.35 minutes to walk to art school. After asking my friend who works on a bar (and kindly timed herself at work) it was found that it takes 17 seconds to pour a pint of Tennents. This works out as 3.5 pints of Tennents every minute. Doing some simple maths the answer was found.
69 pints of Tennents can be poured in the time it takes to walk from GU to GSA. (nice couple of rounds for the class, eh )
If these calculations donât prove that maths is fun then I donât know what would. Maybe at school they should encourage us to get creative and dream up mathematical scenarios that are relatable to our lives. You can literally calculate anything!
