February – Sikhism

This is part two of my Beyond Belief project, where every month during 2019 I plan to experience a different religion that I know nothing about. This month its Sikhism. I have to admit, this one I knew absolutely nothing about.

There is a large temple-looking place not far from where I live so I dropped in the other day to see what it was about. Turns out it is a gurdwara, which is a temple for Sikhs. The only thing I really knew about Sikhs was that they typically come from Northern India and they wear turbans (at least the men do). I’d never really thought that being Sikh was a stand-alone religion, and just assumed it was some offshoot of Hinduism. That’s definitely not the case.

When I dropped into the gurdwara to take a look, there was a guy with a beard and turban near the entrance measuring up a noticeboard, so I approached and explained that I am trying a different religion every month this year. He put down his measuring tape, then spent the next 90 minutes showing me around, explaining the religion and telling me about the beliefs. His name was Padam, and he was super helpful. He pointed out the large TV screen near the entrance that displayed a piece of scripture for the day, and Iearned that it came from the Guru Granth Sahib, which is the Sikh holy book. It displays a different piece of scripture each day, which is made available from “the opening” of the book at 4am each morning, until 8pm each night. Padam suggested that if I read it, it would contain a personal message that I needed to hear because of me turning up on this day at this time. I read it and maybe I just missed it, because I’m not sure I gleaned anything particular. Maybe it’s just me.

I took off my shoes and put on a head covering and we went into the gurdwara, knelt in front of the holy area where the Guru Granth Sahib was kept, and Padam told me lots and lots of stuff about the Sikh religion.

He stressed that the Sikh religion is extremely egalitarian, and treats every human with respect and reverence. A good Sikh, he told me, is peace-loving and is blind to race, to colour, to nationality, to gender. Every human, regardless of who they are, is equal and welcome. Sikhs are welcoming to all other religions, and even though they have been persecuted and even executed over the centuries by Muslim and Mughal invaders, they still harbour no ill feelings towards other religions or races.

I learned that the word “Sikh” actually translates as “learner”. Does that make me a Sikh? Probably not. But I was definitely learning. I learned that Sikhism is a monotheistic religion (one god) but that god is a universal god, acknowledged as the same spiritual creative force as recognised by other religions. The message of this god is communicated through Gurus, starting with the first one, Guru Nanak in the 1500s, and then a succession of other Gurus who became the messengers of this god on earth. The holy book, the Guru Granth Sahib, was steadily edited and extended by the successive line of gurus that followed, each adding more wisdom to it. I asked Padam who the current living guru was and he pointed to the book, which I didn’t really understand right away, but it turns out that the tenth guru, Guru Gobind Singh, named the book as his successor, and the book itself has been “the Guru” ever since. (India is famous for outsourcing, but I never expected something like this!) The book is treated as a real living human person, complete with a real funeral when a copy gets too old to keep using.

The other thing I learned about was “The 5 Ks”, or the symbols that every practicing Sikh carries with them at all times. They are kēs (uncut hair, which is why most Sikh men have beards and under the turban usually long hair), kaṅghā (a small wooden comb kept in the hair), kaṛā (circular steel or iron bracelet designed to both represent the eternal nature of god, but also to represent a handcuff, connecting them to god), kirpān (a small sword or dagger carried on their person. Padam said that Sikhs have special permission to carry the dagger under Australian law), and kacchera (the special underpants designed to remind them of chastity and faithfulness).

Things must come in fives because there are also five things that Sikhs try to avoid. They are referred to as the “Five Thieves” – Lust, Anger, Greed, Attachment, and Ego. Padam spent quite a bit of time explaining the meaning of these and the effect it has on the way they approach life, but I probably can’t do it justice in this blog post, which is already getting long! The wikipedia article about Sikhism is very good if you want to learn more.

Before I left, Padam invited me to come back on Sunday to experience part of the Kirtan certemony and stay for Langar. I turned up at about 12:00pm and sat in on the holy prayers being sung, then the scriptures being read, before heading downstairs to join Langar. Langar is a community meal, provided free to anyone who turns up. You sit on the floor with rows of other people, with a large metal dish in front of you, and people come around and put food on it. It’s all vegetarian, with dhaal, flatbread, rice, aloo, and salad. It’s quite the communal experience.

So that’s my investigation to Sikhism. It struck me as a really nice religion that has a whole lot of interesting traditions, history and beliefs, and some very friendly and welcoming people. I’m not about to convert (to this or any other religion) but I’m glad I checked it out and know a little bit more about it now.

Now, which religion will I try next month? Leave a comment with your ideas! Also, I’d love your comments on this project of trying a different religion each month. Is it a good idea? A dumb idea? Is there something you think I should do differently?

Risk vs Reward – Lessons from the Road

Open road

I spent a few hours this afternoon driving the nearly 200km from Sydney to Bathurst for a day of work in a Bathurst school tomorrow. As I crossed the Blue Mountains and went past Lithgow, the roads open up a little and there are longer, straighter faster stretches of road. On one particularly long straight stretch of road I noticed that my steering wheel hung ever so slightly to the right even though I was driving in a straight line. It wasn’t enough to really bother me, but I started to wonder why it was like that and what it would take to fix it so the steering wheel was perfectly neutral while driving in a straight line. I’m sure the reason had something to do with the camber of the road, and I realised that I do in fact have some level of understanding of how a vehicle’s steering system works. How did I know this? As I pondered the question I remembered back to my very first car and how I had – on several occasions – pulled the steering wheel off and put it back on again.

VW Type 3You might be wondering what caused me to remove and replace the steering wheel on my car.  I mean, who does that? As I tried to remember the reason for why I would be disassembling parts of my car, it dawned on me that I used to take that old 1970 Volkswagen Type III apart and put it back to together again not because there was anything wrong with it, but simply because I could. Yes, I used to pull things apart on that car and put them back together again just for the fun of it and to try to understand how things worked.

There were many times where I pulled my VW apart and couldn’t figure out how to put it back together, and it was off the road for a few days until I could work it out. Back then, that didn’t seem like a big deal. And the value in learning how my car worked seemed a small price to pay for the inconvenience of having it off the road temporarily.  Since the VW I’ve had several other cars that I’ve been quite willing to pull apart and try to put back together, simply because I wanted to know how they worked. Engines, gearboxes, diffs… I’ve had all these things in pieces just because I was curious about what was inside and how things worked.

As I drove along in my current car, a 2015 Mitsubishi ASX, I pondered the prospect of pulling the steering wheel off and putting it back on again, adjusting it by one spline and wondering if that might fix my steering wheel’s droop to the right. As I thought about doing this, I realised that I honestly wouldn’t attempt it on the Mitsubishi, not only because it was probably way more complex than my old VW, but it was more likely to be an expensive repair if I messed it up.  Could I work out how to remove and replace the steering wheel on my current car? Sure. But would I? Nah, probably not.

And I got to thinking about why that is. I’m still a curious person and I still like to know how things work. But the idea of taking my 2015 ASX apart and putting it back together again – for fun – is just not something I’d consider, even though I’ve done it to several of the cars I’ve owned over the years.

What was different? As I thought about this, I wondered if it was the fact that the newer and more expensive the car, the less inclined I would be to tinker with it just for fun. My ASX cost about $26,000. My first VW cost $800.  There was a lot less to lose with the VW if I got it wrong.

This got me thinking about the learning process and about the balance between risk and reward. Unless you are prepared to take the risk of breaking something, you’re probably not going to reap the reward of learning. I don’t really know exactly how the steering wheel on my ASX works because I’ve not attempted to pull it apart, and so I will probably remain fairly ignorant of its inner workings. That’s just a risk vs reward situation I’m going to accept for now. This car is simply too expensive if I fuck it up.

As a teacher, over the years I’ve done a lot of great projects with kids. Some have been amazingly successful and have dramatically changed the way I think about the teaching and learning process. And some have been total disasters. But the value for me as a teacher – as a teacher who wants to continually be getting better at what I do – comes from being willing to take that risk that even if things don’t work out, the value of what I learn from trying makes it worthwhile anyway.

For several years I worked in a fancy high-falutin private school. I won’t say that I was being completely risk averse during my time there, but I also don’t think I took as many big gambles and tried as many radical things as I once would have, simply because the stakes were a little higher if I happened to mess it up. This school had a reputation to protect, demanding parents to keep happy, and there were more policy-driven hoops to jump through to really try outrageous ideas. By contrast, I’ve worked in several schools that had far less to lose, and in those schools it was always much easier to try new ideas because it didn’t matter so much whether they worked or not. Most of the best innovation seems to come from situations where failing is most definitely an option.

It’s nice to be well resourced and have great facilities. But you can do an awful lot of great stuff in a school with very limited resources. You don’t need a lot of money or resources or fancy facilities to be innovative and try new ideas. You just need to be willing to try stuff, and to not worry about whether it works or not.

The other things that struck me as I thought about this idea is that some of the cheapest, shittiest cars I’ve ever owned – the ones I had no issue pulling apart and tinkering with – are the ones that gave me the fondest memories and the deepest emotional attachment. The last few cars I’ve owned have been brand new, reasonably expensive, “nice” cars, but I have very little emotional attachment to them at all. They are just transport. Yes they are comfortable, reliable and pleasant to drive, but that’s about it. The cars I’ve loved owning the most over the years were mostly second-hand, cheap, with lots of quirky flaws yet I look back at the experiences they gave me with such great memories and the knowledge that they even shaped me as a person.  I see some parallels with the classroom there too.

Sometimes you can put that steering wheel back after you pull it apart, and sometimes you can’t. The point is not that everything you do needs to work. The real point is that everything you do should be an opportunity to be a better learner.

The Power Of Spreadsheets

I had a knock on our front door a few weeks ago. It was a young English guy going door to door for an electricity retailer, trying to get me to switch my power company.  As it turns out, it was his first day so he didn’t really know a lot about what he was selling and couldn’t answer many of my questions in detail. To be fair, I can be a bit analytical about these things and I don’t think he was prepared for so many questions. His spiel was basically “You should switch to us because we are better”, but when I asked about the rates they charge, all he could respond with was “We have really good rates”.

If you ever come knocking on my door, whether you’re trying to get me to switch energy companies, or convince me that Jesus loves me, you better be prepared to engage. I ask lots of questions. You better have answers.

So I grabbed my most recent power bill, and asked him exactly what their rates were per KWh. He had never heard of a Time Of Use meter (TOU), which our house uses, so I had to explain the concepts of Peak, Shoulder and Off Peak rates to him. As we compared the rates, we both learned that his company’s “really good rates” were not quite as good as he had been led to believe.  Compared to what we were currently paying, they were slightly cheaper for Peak and Shoulder, and quite a bit more for Off Peak.  It was an interesting discussion and I told him I would take the data he provided and think about it.

When I think about data, I do it with a spreadsheet. I often amazes me how few people really understand the power of a spreadsheet to analyse numbers. Even with just a few simple formulas, it’s possible to dig into numbers and see what they really represent.  Especially with consumer level data – like knowing how much things really cost – it astounds me that more people don’t know how to make sense of the numbers for their basic expenses.

So I knocked up a spreadsheet in Google Sheets. I transferred the KWh usage from my last power bill onto the sheet (which was a little tricky as there was a rate change part way through the quarter, so I had to calculate the different rate amounts and add them together for the total) but in the end was able to correctly derive the exact same $429 figure as I actually paid. Just that part of the exercise was useful as it helped me understand exactly how my power bill was calculated. (Do you understand how yours is calculated?) I then projected the amount of my next quarterly power bill – $529 – assuming the usage was the same, but with the latest rates.

Then I copied the usage data and plugged in the KWh rates being quoted to me by my door knocking friend. His company was offering a 15% pay-on-time discount on the bill (but only on the actual power usage, not the supply charge, as I found out later by reading the fine print). As it turns out, his company – Simply Energy – was indeed cheaper than my current provider, coming in at $439 for the same usage and a saving of $89.88. Not bad.

But wait, it got me thinking. Could I do even better? A quick internet search turned up a power provider called Red Energy. Red Energy was highly recommended by Canstar, so I found their rates and plugged them into my spreadsheet. Their KWh rates were cheaper, however they only offered a 10% pay-on-time discount, but it was on the whole bill not just the consumption component.  Can you see why you really need a spreadsheet to analyse this data if you want to make any informed decisions? I’m sure that companies deliberately calculate their charges using different formulas to their competition, just to make it harder for consumers to make apples-to-apples comparisons. Thank goodness for spreadsheets and knowing how to use them.

Red Energy was not actually the cheapest option, but they were close enough and the one I felt best about as they are a 100% Australian owned company. So I called them, and made the switch.

And then the fun started. Yesterday I got a call from Energy Australia, my current power provider, telling me what a valued customer I am and how much they wanted to keep my business. So much so that they offered an ongoing 26% (!) pay-on-time discount on my power bill. While that certainly sounded like an attractive deal, their actual rates were still higher, so how can you tell?  Yes, with a spreadsheet.

As the Energy Australia rep was wooing me with enticing offers I was able to say “Hang on, I have a spreadsheet!”  I quickly entered their data into the sheet and was now discussing the options knowing exactly what I was talking about. Having data is powerful.  Turns out it was a good deal, so I decided to remain with my original provider (although I was a little bit annoyed that you need to threaten to leave them before they suddenly discovered they can offer me a discount!)

Now I had to call Red Energy and tell them I was cancelling the switch. But, surprise surprise, Red has a customer retention department as well and they didn’t want to lose me as a potential new customer either. So they upped the ante to a 12% pay-on-time discount AND a $100 rebate on my next bill. Into the spreadsheet that new data went. And it turns out that when you take all of that into account, Red wins – by $6.34 annually.  So I decided to stick with my decision to switch after all.

You can check out the spreadsheet I made here if you are interested.

I think there are a couple of lessons here…

  1. If you want to be a canny consumer, you need to have the facts. Many companies give you information that is confusing, incomplete or just misleading. Take the time to analyse the data for yourself so you know the reality of their claims.
  2. If you want to save money on basic bills, then leave your current provider (or at least threaten to). Switching your power, phone, gas, or other service to a competitor is likely to get their customer retention department calling with a much sweeter deal than you currently get.
  3. Learn to use a spreadsheet! They are a simple tool, but oh so powerful. I can tell you, at least anecdotally, that most people I meet have absolutely no idea how to use one. Don’t be one of those people.
  4. If buying locally matters to you at all, do some research. Turns out that Energy Australia, despite the name, is a wholly owned Hong Kong company. Red is 100% Australian owned by the Snowy Hydro Scheme. Foreign ownership of Australian companies is an interesting can of worms.

Here the educational part of this blog post…

As a teacher, I see this kind of thing as a brilliant activity for students. What if you gave your learners the basic skills of calculating numbers with a spreadsheet, and then a bunch of different rates from different competing companies and simply asked “Who is offering the best deal?”  This process usually raises lots and lots of questions, and will certainly make them better consumers, better at understanding data, and better users of spreadsheets.

For an example of the kinds of ways you can take this convoluted consumer experience and turn it into a reasonably useful learning task for students, the links below are from a task I have used with my Year 11 students looking into how to figure out the best mobile phone plan. As you will see from looking at the task, it tried to take account of the complexities of the word “best” by introducing a user-centric approach (best for who?) and encouraging them to really dig into the information being provided to make sense of it. I’ve also included a grading rubric to give you an idea of how I graded this task.
