Romans series
I'll try to post a few random thoughts as the series goes on, but don't expect anything regular or profound. Just pray that I would gets lots out of the series, whether I blog about it or not.

Home Alone
It's very strange.
I can probably count the time I've been at home alone in the last year on one hand. Today, Dave & SP have popped to the park for some fun, while I finish off a photobook.
It's lovely, but I miss them.

National Engineering Week - Special Edition
To wrap up the series I want to try and give a brief introduction to microwave engineering, which is my field of professional interest. Microwave engineering is all about the generation, transmission, detection, and processing of signals at microwave frequencies. What are microwave frequencies you ask? Anything from 300 MHz to 30 GHz is considered microwave. 30 GHz to 300 GHz is considered millimetre wave. The reason for this is that at 30 GHz, the wavelength of the signal (i.e. the distance between one peak and the next) is 10 millimetres. Below microwave frequencies we have radio frequency in the 30-300 MHz range. Oh, and MHz is short for megahertz, which means the signal goes up and down one million times per second. GHz is short for gigahertz - one billion times per second. In perspective, humans can hear frequencies from around 80 Hz up to 40 kHz. Concert pitch, or A-440 is 440 cycles per second.
Some situations where people use microwaves:
- FM radio (RF, around the 100 MHz region)
- cordless phones, mobile phones, bluetooth and any of your wi-fi/wireless network connections (anywhere from 900 MHz to 5.4 GHz depending on what it is)
- GPS navigation (around 1.3-1.5 GHz)
- Microwave ovens
- Point to point communication links (the dishes that look like a squat grey cylinder on the side of buildings and TV towers)
- Police radar
- Weather radar
- Vehicle anti-collision radar
- Air traffic control radar
- Military radars
My work is mostly related to the last item on the list. In the military environment there are basically two groups of microwavers. Those on the radar side, who try to generate signals to find and track other ships/aircraft/whatever, and those on the countermeasures side, who try to pick up the radar before it sees you, or send out a fake signal to make the radar think you're somewhere else.
I don't actually build the systems that do those sort of things. The company where I work builds some of the components that go into those systems. It's interesting, and it's challenging because not only do you have to deal with very small spaces (I know aeroplanes look big on the outside, but there's not much space inside for this sort of thing) you also have to deal with severe environmental conditions like very high temperatures (85 Celsius is normal), very low temperatures (it gets down to below -40 Celsius at cruising altitude), dust, salt, vibration, and high shocks (like when a missile hits a few metres away, or when an aircraft launches from a catapult).
The observant among you would also have noted that I mentioned photonics a few days ago. Photonics is a branch of fibre optics, using light waves to transmit and process these signals. The cables that make international phone calls and the internet possible are all fibre optic cables now. The infamous national broadband network (which is a great concept turned into a stinking mound of sewerage by the government and beauraucrats) also uses fibre, lots of it.
Naturally I think all of the above are some of the great things that microwave engineers are involved in. When we get things wrong they're not usually as spectacular as a bridge falling down, but still worth acknowledging. The microwave mortuary has a lot reports, scroll down to an entry from late 2006 for one that I'm quite familiar with... Warning: this page has heaps of photos so will take a while to load, even over broadband.
So there you have it. Engineers are everywhere, doing all sorts of stuff. Like doctors, we're very useful unless we make a mistake, which tends to upset people.
Thanks for reading.

National Engineering Week - Electronics
So examples that affect your daily life include: the computer or phone that you're reading this blog on, all the background stuff that makes the internet work, your TV, radio, wristwatch (unless you wind its mechanism every day by hand, it's got electronics in it), digital cameras/video cameras, portable DVD players, speed cameras, red light cameras, smoke alarms, just to name a few.
Although computers are ubiquitous, to the point that even a cheap calculator has more computing power than the Apollo program, and you can buy programmable calculators with more power than could be dreamt of 20 years ago, I think wristwatches are one of the coolest applications of electronics. That's mainly because of an article I read on a flight to Adelaide a few years ago. It was an interview with one of the senior designers at Seiko, talking about all the things they did to make their top end (think 5 figure price tag) watches work. The accuracy of the components, the efficiency of the circuit - most consumer batteries work at milli-amp current levels. This guy could tell you where every micro-amp was used! (There are 1000 micro-amps in a milli-amp if you didn't know). Like a lot of higher end watches these days, it had a small solar cell and other cool tricks to harvest energy from its environment. I wish I could remember more about it, but when you finished the article, you could understand why the watch cost so much, it's an engineering masterpiece.
But electronics engineers still make enough mistakes... like the unintended acceleration problem with Toyota vehicles earlier this year, or Dell's exploding laptop, or the famous calculation problem with early model Pentium chips from Intel.
If you've ever had trouble understanding what I do for a living, come back tomorrow and read our final post in this series. It might help. A little. Maybe.

Fruit & Veg
So my primary treatment is to eat more and eat better. I thought I was doing pretty well, but apparently not.
I just checked out the Qld Government Nutrition Guidelines, and the standard whilst breastfeeding is 5 serves of fruit and 7 serves of veggies per day! I'm pretty sure I haven't been hitting that target very often...
Just as well we get on well with our local fruiterer.
National Engineering Week - Electrical
There's also a distinction that I'd like to make between electrical and electronics. Electrical is all about electricity - power generation and transmission from power stations to users are the big ones, I'll also lump HVAC (which stands for Heating, Ventilation and Air Conditioning) in here too, since they usually use 240V AC (i.e. mains power, the stuff running around in the walls of your house).
Power generation is obviously pretty important, especially in western society. You wouldn't be reading this blog, or catching an electric train without it.
The transmission side of things is just as important though. The big thing with transmission is the concept of loss. Crudely simplified, the power station puts a signal onto the line at their end, but it's smaller when it finally gets to your end. The difference is what we call loss, and it's power that in one way or another is wasted. Now for you to be able to use the energy that you want, the power station has to put extra on at their end to cover the loss in the middle. The more loss, the more they have to do extra, and the more it costs everyone - especially you and me!
Because of this loss, a lot of research is going on into technologies like high temperature superconductors. A superconductor has much less loss than the cables we use today, which would be much better for the power companies. But there's a problem. For a while scientists have been able to make superconductors at low temperature. Really low temperature. Like a couple of hundred degrees below zero temperature. Which is not very practical if you want to get electricity from Tarong to Brisbane. The aim of HTS research is to find a compound that first of all works at reasonable temperatures (say, anything about zero degrees C) and second of all can be manufactured in the quantities needed to replace the current grid.
So what's spectactular about electrical engineering? Aside from actually generating power and reliably hooking up multiple power stations to users who are constantly turning things on and off, but without having the whole system fall over? Well, one example would be the solar power towers in Spain. They were also featured in Richard Hammonds Engineering Connections, which I mentioned the other day.
What happens when things go wrong in electrical engineering? Well, if you happened to be in a small town in the Ukraine on 26 April 1986, you might not have been very happy with the local power company. That's when the Chernobyl disaster happened. In all fairness to the electrical guys, Chernobyl was a result of many, many things going wrong, but since it's a power plant, it fits with today's theme. Another example - the power grid in the north east US can be a bit unreliable, as massive blackouts in 1965 and 2003 showed.
Tomorrow, we'll find out what makes electronics distinct from electrical engineering.

National Engineering Week - Mechanical
Mechanical engineering shows up all over the place: cars, trucks, trains, aeroplanes, ships, bicycles, escalators, elevators, refrigerators, mining, just to name a handful.
Materials engineering is usually considered a subset of mechanical engineering, and is particularly interesting. Materials engineers do a couple of things. One, they take existing materials and work out what its characteristics are. That is, if I take a rod of material X, will it rust? Will it pass electricity? Will it pass light? How dense is it? Can I crush it? Will it bend or will it break immediately? When it breaks, does it send thousands of deadly projectiles across the workshop? Does it burn/explode/other cool but dangerous things?
Another thing that materials engineers do is to come up with improved compounds for existing materials, or brand new compounds that have certain desirable characteristics. The "composite materials" used in the new Boeing 787 are one example of this.
Like their civil cousins, mechanical engineers do some pretty spectacular things: aircraft carriers, ferraris, or my personal favourite, the Lockheed Martin SR-71 Blackbird.
Also like their civil cousins, mechanical failures can be difficult to hide, like the Hindenburg.
Tomorrow, electrical engineering.
*Not all mechanical engineers are interested in things that move. Where I work, things don't move but our mechanical engineers are very interested in things like how to get heat out, how to make it light but still strong enough to be bolted to an aeroplane, stuff like that.

National Engineering Week - Civil
You can't go a single day without relying on something done by a civil engineer. Roads, bridges, water supply, sewerage, shopping centres/office towers - they all fall under the civil umbrella. Even planning the sequence on the traffic lights to keep the traffic moving smoothly is usually a civil task.
Environmental engineering is a growing sub-set of civil engineering. As the name suggests, they usually deal with things like environmental impact statements and water quality.
Civil engineers do some pretty spectacular things, like the Milau Viaduct in Spain (featured in Richard Hammond's Engineering Connections, which just by the way is a fantastic show, even if you're not an engineer).
Of course, they're human and they don't always get things right... Footage of the Tacoma Narrows bridge collapse in 1940 is something that almost every first year engineering student sees.
Tomorrow, mechanical engineering.

Romans 1:1-17, Part 1
Key Verse: Romans 1:16-17There's a lot in the first 17 verses of Romans! Some things we talked about at Bible Study:
I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile. For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last, just as it is written: "The righteous will live by faith."
Paul is an ambassador to the Romans, from God. He has the authority to bring them God's message. Which is...
The gospel. I discovered that I shouldn't criticise Paul's wordiness when I can't do any better. My supposedly 'simple statement' to summarise the gospel was:
'a powerful message, previously promised by the prophets, which Paul now preaches on behalf of God and his Son, about his Son, which reveals God's righteousness and plan for salvation for all.'Yeah, not very simple. And there's lots that I missed. I guess that's why we have the whole book of Romans to fully explain it. I'm looking forward to getting stuck in.
I'm on creche on Sunday but I'll try very hard to listen to, or at least read, the sermon on Monday sometime. Stay tuned.

Child Modelling Update
We went to the interview, which was more like a sales pitch, but I guess the agent was watching Sam as well.
She must have liked what she saw, because we got a phone call the next day saying that they'd like to have him on their books.
But in those 24 hours, we'd already decided to say no if they asked. Apart from the $600ish per year sign-up fee, it seems like an industry that you really have to throw yourself into - there's no dabbling.
So, as cute and fun as it might have been, child modelling is not for us. Too many other, more worthwhile, opportunities in this season of life.

30 days of prayer for the muslim world
Ramadan is August 11 to September 9. Thanks to the prayer notes, I'm expecting to learn a lot about it and Islam in general during that time.
Bloggy Birthday
Sorry there haven't been many posts recently. I have many in my head, but they don't seem to be getting into the computer. Expect updates soon on Norwex, Nana May's, child modelling, and general life. Boy, I've got some writing to do...

Abigail Grace
Today, I heard that some other (unconnected) friends have given their new baby girl the same name.
I have nothing profound to say, just a heavy sadness in my heart, for myself and for many loved ones grieving different deaths at the moment. And this song continuously in my head.
Come, Lord Jesus.

5 reasons I love knitting
3. It keeps my hands busy, which reduces the temptation to scratch my eczema.
4. It's useful. My knitted soakers (I'm currently working on the 4th) do a great job of keeping SPs pants dry, so I do less washing.
5. It gives me a sense of olde world charm, and somehow a connection with women of times past. Ah, the simple life.

Other people think he's cute too
My general thought is that as long as SP has fun, it doesn't interfere with more important things, and the photos aren't sexualised, I'm happy with it. In reality, whether or not we sign up depends a lot on the membership price, which the website is suspiciously quiet about.
What do you think?

Long arms and long legs make SP a tall boy
I couldn't quite believe that he could get a block this far from the edge of our chest freezer though. Yikes!
No more corny titles, please...
- The cayenne peppers were the best of the lot, growing fairly easily and although we only got half a dozen, they're good sized and pack a punch! Currently drying on the window sill, I'll need to grind them down soon...
- The lettuce did a few weeks of lunches...
- The carrots were all about as thick as a piece of string...
- The zucchini started well, then got some form of blight, and right when they were flowering I decided to cover them with mosquito netting to try and keep out whatever was eating things. What's that, zucchini needs bees to pollenate and turn flowers into fruit? Bother...
- The beans, and spinach just died...
- The onions are still in, watch this space...
But today's harvest was the corn - of the eight or ten original plants, only a few survived, and from them I managed to get four cobs.
As you can see (that's a teaspoon in the top photo by the way) it's not going to win prizes at the RNA any time soon. But after cooking, well, it tastes like corn, and the kernels are actually a much richer, deeper yellow than frozen corn from the supermarket. The store-bought stuff looks anaemic by comparison.
So as much as I love time in the country, it's probably best that I'm not trying to feed a family on home-grown produce just yet. Although there's quite probably a family or two of possums that are doing very well out of our little vegie patch.
Now I'm looking forward to spring and summer, and seeing if the grapevine or mulberry bush produce anything of interest.

Celebrating our 59th post
It'll soon be our blog's first birthday. Which means it'll soon be our son's first birthday! Yikes!!
Nappy cover pics
I've got the body of the second cover knitted up; now to finish the i-cord and add the cuffs. The wool is a funky purple-plum mix - I'm a bit sorry it's designed to be covered by clothing :)
I figure 5 covers is a good stash. I wonder if I'll get bored with knitting before then?
A fun weekend
Saturday afternoon: Dave helped his lovely sister buy a car, and SP & I checked out the Pregnancy, Babies & Children's Expo at the convention centre. I think it's worth making it an annual event just for the animal farm.
Saturday night: Date night. Usually we go out one week then stay in & read a book together the next week. But we both have croaky voices at the moment so we watched a taped Masterchef Masterclass instead. Now I want to make bread.
Sunday morning: Church. I was playing the piano & had fun incorporating some tips from Twist. Then we all headed down to the fete for morning tea.
Sunday afternoon: Chilled out at Mum's while Dave did his shift at the fete. I mostly listened to Mum & SP playing while I knitted. Lovely :)
Sunday night: Now that my work has switched to Mondays (from Thursdays), a relaxed do-nothing Sunday evening leads to an unnecessarily frantic Monday morning. Last night I was pleased to discover that half an hour is plenty to do all the 'getting ready for the week' bits & pieces that make such a difference.
Into the week we go...
Tuesday, June 15, 2010
Finished - sort of
I was going to post a photo but SP celebrated the occasion by doing a mammoth, leaky poo which dirtied said cover. Another time.

Our not-so-perfect life
It's occurred to me lately that life according to this blog probably sounds really good and easy and straightforward. Particularly after posts like this.
Rest assured, you're not alone*. Most days aren't like that. If I remember rightly, me hitting the 'post' button on that particular post and SP waking from his 20 minute nap were simultaneous, and while I don't remember exactly what I did for the rest of the day, I'm pretty sure I didn't do any knitting.
There are plenty of days when the house is a mess, the washing piles up, SP seems to spend the whole day either attached to my leg or getting into things he shouldn't, dinner is scrambled eggs or freezer leftovers AGAIN, and Dave's return home is marked by a cry of 'Yay, Daddy's come to rescue us!' But on those days, the last thing I feel like doing is blogging, even if I could find the time and brainspace to do so.
Life is messy, complicated and exhausting. I'm lazy, I'm selfish, I'm annoying. I let people down, I hurt them, I disappoint them and I take them for granted, especially those I love most. This is real life in a sinful world.
Next time I look like I've got it all together, please stop me. I need help to let down my mask of perfection and show the real me.
* Hat-tip to Simone

Knitting Update
Next steps: finish my decreasing, weave in the stitches from the stitch holder (no idea how to do this - I'm hoping youtube will be helpful), knit an i-cord to tie through the eyelets, and maybe do some cuffs.
I'm getting a real buzz from all this craftiness, but I suspect my housework is suffering. Hmm, how to find a balance... Any ideas?

A good start to the day
I foresee lots of knitting today :)

Getting the message across
Problem: I’ve been pretty disengaged from bible study this term:
- we’re not in a part of the bible that I know really well
- I haven’t often been in church to hear the sermons, and haven’t made the effort to read or listen to them later.
- I haven’t been reading the passages in my own time or making any real effort to process them after bible study
… all of which means that, while I have some understanding of the bare bones plot, because I’ve still been turning up each week, I’ve been taking very little away in terms of broader themes and application.
God’s Solution: My turn to lead the group this week! Which meant...
- I had to read the passage beforehand
- when I got confused with the plot and characters, I couldn’t just zone out
- when I felt young and inexperienced, ill-equipped to deal with the deeper themes on the same level as others in the group, I had to keep grappling
- sin makes life messy. I’m been feeling annoyed with the after-effects of sin in my own family, but I need to accept the situation, trust that God knows the way forward even when I don’t, and work on loving people anyway.
- sin is serious. I need to stop ignoring, stop making excuses and fight temptation.
As it turned out, I did a shocking job of leading the study (and no, I’m not looking for warm fuzzies from those who were there), but I suspect I learnt a lot more than I would have otherwise.
God is good.

Knitting Update
Acquire needles: not yet.
But this afternoon I have started actual knitting! With some old wool, a couple of paintbrushes (yes, very sad), a book from the library and this video, I've learnt to cast on & do a basic knit stitch. Yay! Already I can see why people get addicted - there's something relaxing yet satisfying about turning a strand of wool into a piece of fabric. I wonder how long the enthusiasm will hold out...

Another hairbrained scheme
In an attempt to satisfy my recent creative streak and to solve a problem, I'm going to give these knitted soakers a go. Yes, I may well be insane. I've never knitted anything more than a dolls-house size blanket in my life. Much help is likely to be required from the other females in the family.
First step, acquire wool and a circular needle.

A fruitful fete day
- small (baby hand size) blocks
- an alphabet book
- a lift-the-flap book
After getting settled, we had a look around the book stall. And what did I find? An alphabet lift-the-flap book. And a variety of other interesting-looking things - I'm terrible at book stalls. But for $1 a book, I figure you can't go too far wrong.
The rest of the day was a lot of fun too, especially the couple of hours in the afternoon when we just hung out on the grass, listened to some great live musicians (aka the school kids) and Sam got to play in the dirt.

Nana May's Update
It hasn't magically cured everything, but I'm less itchy, less red and some patches on my hands that I'd assumed would be red & scarred forever are starting to return to their previous colour.
Highly recommended.

Nana May's Magic Hands
My eczema has been playing up lately. Not fun. I hate being itchy, and I don't love looking red and inflamed either.
So when Dave noticed a stall offering free 60 second hand treatments at the South Bank markets last night, I gave it a go. Rubbing a salty, oily solution over my dry hands felt very odd, but when it was washed off… heaven!
After a bit more wandering, we went back and bought a tub of Nana May's Magic Hands. I'd like to think this was a considered decision, and not jumping on some bandwagon out of desperation. I'm not in the habit of buying anything that a guru tells me will work.
Jeanie told me to use it morning and night until my eczema clears (about 7 days) and then twice a week. She was very optimistic. And after just 2 treatments on my hands and 1 on other areas, so am I. But 7 days to clear skin seems a little unrealistic.
I'll post again in a week's time.

Our Echo Experience
This Easter, we had the privilege of visiting Echo Station, northwest of Roma, as guests of Dave’s Uncle Allen and Aunty Barb, where the cattle roam and the sorghum grows, and kangaroos and emus are ordinary sights.
Mmmm, chocolate
So hop on over to the website to find out more, and next time you're buying some chocolate, look for the fairtrade logo, not just the bottom line.
*Yes, despite my complete disregard for facebook and twitter, it appears that they have some uses, especially when the twitter feed is live on the blog.
