What's the purpose of the Scilla blog?

Previous | Part 1 of a series | Next

Most blogs focus on a particular topic, but this one covers all sorts of topics. One reason for this is that to post enough items to keep a blog interesting takes time. Posting to two or three more focused blogs would take two or three times as much effort, otherwise they would be updated two or three times less often.

I have lots of interests, lots of stuff to share. I want this blog to reflect real life, I want it to be a way for my friends to keep track of what I do and also perhaps an introduction to areas of my life they might know little about.

Do you compartmentalise your life? I do. Not deliberately, but when I'm with scientists we talk science, when I'm with Christians we talk faith, when I'm with photographers we talk about images. It's natural. To help you I've provided a tag cloud at the top of the left hand column, click on topics that interest you and you will only see posts on those topics.

Over the next few days I plan to begin posting brief introductions to each of those topic areas explaining why I'm interested, what it involves, and how it affects my life. These are not going to be technical posts, they'll be light and easy to follow - for anyone. I promise!

Have you ever thought that there must be connections between all the different things you do? If in no other way they are linked because they're all things you enjoy, or else you do them because something else about your life demands it. Either way, there's a link.

I'll try to draw out some of the links I see as I go along. Some are clearly linked, like astronomy and photography, or photography and garden, or transport and environment. But what about garden and persecution?

I plan to work through in alphabetical order so I'll be starting with astronomy and working right through to underground church.

These posts will be interspersed with others. There are bound to be items just waiting to be written on a host of other things.

Watch this space...

Photography, something I love

Previous | Part 2 of a series | Next

We should all find, make, or steal the time to do at least one thing that we really, really love. Come on now, you know I'm right. In this modern age there are so many pressures on us that sometimes we struggle just to get from one day to the next. The trouble with that is simple. You will only live this day one single time, you have just one bite at it. So spend part of it doing something fun, or rewarding, or delightful. It's not decadent to do that, it's an expression of who you are, to yourself, to your family, to friends and aquaintances, and to the King of Creation too. Unless of course you think he's not interested in who you are, or think he doesn't exist. But even then, you still owe it to yourself and to those around you to express the real you.

Something I love is to capture images of things that impress me by their beauty, things that amaze me.

Here's a slideshow of photos I took during the last two months. I hope you enjoy viewing them as much as I enjoyed taking them. Leave me a comment and tell me which image is your favourite (and why).

You can also open the full version of the gallery with options for viewing the photos at much larger sizes, or even downloading the originals. Each picture tells a story, can you work out what it might be? Once you're in the full gallery you can comment on each picture individually if you want to.

Things you can do with cornflour

Some You Tube videos of cornflour have been doing the rounds and they're quite fascinating to watch.

You might think cornflour is only good for thickening sauces or making cornbread (yumm). Well you'd be wrong.

You can try running on it...



Or you can pop it on an upturned bass speaker and play it some music!...



So what's going on? Why is cornstarch so goofy and weird?

It's something called non-newtonian behaviour. Slow, gentle movements meet little resistance to flow; but sudden, forceful motion causes the matrix to lock up and resistance becomes much, much stronger. If you want to know more, read the Wikipedia articles on cornstarch and non-newtonian fluid.

Oh, and don't forget to enjoy the videos :-)

Eaton Ford - Prayer

Only very brief notes were made this week. We spent much of the time talking, but we also prayed for Pam's Mum who has been unwell, and for Jim and Sean who have both been heavily overworked.

Let my people go

I wanted to reply to Frank Viola's recent blog post 'Favourite Song of the Season', but comments were closed so I'm going to reply here instead. Do visit Frank's item by clicking the link above (or the image), read the words and listen to the song. I agree with Frank, it's a great song. I love it!

The theme is one that's been very real to me for many years. It applies to the Church today, indeed it's applied to the church for the bulk of its history. Let my people go!

What do I mean? Let's say that Egypt represents the world, and Pharaoh therefore represents the Prince of this world. Meanwhile the Israelites, Yahweh's chosen people, represent the Church. The problem the Israelites had was that not only had they got into Egypt, but Egypt had also got into them. They arrived in Joseph's day, hungry and desperate and glad to find a land where there was food enough to go around. As the generations passed they became more and more dependent upon the Egyptians. At the same time, as far as the Egyptians were concerned they became a serious refugee and immigration problem, aliens in the land.

It has always seemed clear to me that the Church has gone to live in the world. The Church has adopted the world's methods of management, organisation, authority, and structure. The methods seem to work for the world and have therefore been seen as a good way to do things. Maybe we have become so used to them that they appear to be the only way to do things! If it works for government and for big business, surely it will also work for the Church?

Well, after a fashion these methods seem to work for the Church, but at a serious price. Either we do things our way or we do them the Lord's way, but we can't mix and match. We really can't. We have been making bricks without straw, and it is so, so hard for us! And when we cried out in despair, Yahweh heard us and has come to remind us that in Christ we are truly a free people.

In the end Yahweh calls Israel out of Egypt. He is also calling the Church out of the world, but like Pharaoh, the Prince of this world is unwilling to let us go. And as the Church walks away from the world it heads out, like Israel, into the wilderness. What did Israel do? They complained most bitterly. 'Why has Yahweh brought us out into the wilderness to die? At least in Egypt we ate all we needed.' So the Lord sent manna and then they complained that it was not the kind of food they wanted!

We are just the same. We hanker after the reliable and safe provision of the world rather than trust to the uncertainties and hardships of the wilderness. Yet the wilderness is just a place we must pass through to arrive at the promised land, flowing with milk and honey. But we cry, 'It's too hard, we don't like it, we're afraid, we want to go back to the world's ways, we'll make a god of gold and worship that, we will die in this wilderness, there's nothing to drink, the land he promised us is full of giants, we can never succeed.'

Listen, we have to leave the world's ways. We are in it of course, but we should never have become of it. We have to leave our comfort zones and go. We have to trudge through the wilderness, we have to learn to depend on the Lord alone, we have to believe that in him and with him we are safe and will succeed in the task he's given us.

Yes, not only have we been in the world, but the world has been in us. Enough! If you want the detailed story, read 'Pagan Christianity' by Frank Viola and George Barna. If your eyes are open the book will open them even wider. It will explain how the church came to be the slave of the world, both in it and of it. And it will explain how the Church needs to throw off everything that encumbers her and go back to the Promised Land. And live in it. Like Israel, the Church was originally in this land of promise but left, and now it's time to go back again to our inheritance.

Yes, I like the song. 'Let my people go!' Remember who it was who told Moses to speak that way to Pharaoh! It was the Creator of this universe, the King of Kings, Yahweh speaking out of his Shekinah Glory. If he says 'Let my people go' who can stand against him? So what reason can we possibly have to be afraid? Hmm?

Get walking!

Improving car efficiency

This is an idea I had recently for improving the efficiency of internal combustion engined vehicles. 'Green' is becoming the watchword of the decade (rightly so), and anything that can reduce fuel consumption is a good thing whether your car burns petrol, diesel, or biofuel.

Engines run much more efficiently when they are at their working temperature. Every increment in starting temperature will increase initial efficiency and reduce the time required to reach full working temperature, a double benefit by starting 'further up the curve'.

For very little extra manufacturing expense I suggest fitting a network of piping between the roof of a car and its internal lining. The network would be fed engine coolant by flow and return pipes that could be concealed inside the front pillars between the windscreen and side windows. The coolant would be warmed by solar energy and would flow to the cold engine when the vehicle is idle, returning to the roof network to pick up more heat.

A miniature pump in the engine compartment would keep the fluid flowing slowly, I suggest the pump should be controlled by temperature sensors so that when the water in the roof network is not warmer than the engine block the pump does not operate.

This scheme would improve the efficiency of any internal combustion powered vehicle, cars (including hybrids), lorries, buses, boats, aircraft etc. It would work while your car was parked in town or at the office or outside your home. On a hot day it would have the added benefit of keeping the car slightly cooler, on a cold day it would enable the heater to start working a little sooner. And the fuel efficiency would increase - especially for those short journeys.

There - I've published it. It cannot now be patented (at least in the basic form described here). It's available to any vehicle manufacturer or add-on kit maker that cares to use it.
