Stereoscopic vision and God

December 17th, 2018

Stereoscopic vision is a useful and subtle aspect of how we, and some animals, see. Because our two eyes both face the front (unlike some animals and insects whose eyes face more left and right), they both see similar but subtly different views. For example, if two objects are in line, one behind the other, our left eye will see the object furthest away slightly to the left, while the right eye sees it slightly to the right.

The brain is able to notice this difference, and correctly infer that the distance to the rear object is greater. Without this stereoscopic vision it would be harder to estimate how far away objects are, and whether they are moving towards us, or away.

You see this in this stereo photo of a man in a narrow laneway. The two pictures are almost the same, but the left photo (which is what the left eye would see) shows more of the lane to the left of the man (as we see it) than what the right photo shows.

Award-winning physicist Aron Wall observes that knowing God may require something analogous to stereoscopic vision.

Do not adjust your set, normal transmission is resuming

December 8th, 2018

Those readers who subscribe to this blog may have noticed that about 3 weeks ago all the comments disappeared, and I haven’t posted in that time. And you may have received a strange email about an odd post. The three are related.

Three weeks ago the WordPress database was corrupted, I don’t know how. Fortunately I had almost up-to-date backups, and the corruption was just in the field which linked comments to particular posts. So no comments were lost, but they couldn’t appear.

It took a lot of sweat, a steep learning curve and a little panic, but I now understand databases much better and I have restored all but a few comments. I also appreciate the importance of backup, and have learned how to do mine better from now on. It is now (hopefully) business as usual again.

So thanks for your patience (if you noticed any of this).

The doubt that breathes beside you

March 10th, 2018

People move into and out of faith. Probably most of us stay with the religious beliefs we form in our late teens, but a fair number change their basic belief somewhat later.

These changes in belief can be difficult to make and to carry through. But probably nothing is more difficult than when one partner in a close relationship changes their previously deeply held belief and the other does not.

Blogger, author, wife and christian, Stina Kielsmeier-Cook, has given us in The Doubt that Breathes Beside You a beautifully written and heart-breaking story of her experience when her formerly zealous christian husband decided he could no longer believe.

Whether you are a believer or a non-believer, I think you will find her reflections memorable and touching.

God 0 – atheism 5 ?

February 8th, 2018

We all like to think we’re right in our beliefs, whether it be about God, politics or how our football team can play better. The interesting thing is how strongly we can disagree.

A while back I came across an old newspaper column by an atheist, titled The five best reasons not to believe in God, a clever title because it implies that the author has many other reasons not to believe, but he’s just giving us the best ones.

So I was interested to check it out to see how good the best reasons were. Is it really God 0 – atheism 5?

From polite discourse to no discourse

January 5th, 2018

I have been a christian believer for about 55 years, and throughout that time many of my relatives, friends, work colleagues and internet acquaintances have not. Most of the non-believers have been agnostics or ‘don’t cares’, but there have been some atheists, a couple of Buddhists and Jews, a few Muslims and a few whose belief cannot be easily categorised.

And so of course I have had many discussions about belief and one thing stands out – all of the face-to-face discussions I can remembers have been civil and friendly. Disagreements about belief haven’t led to discourtesy. But it seems the internet has changed all that.

History for Atheists

July 7th, 2017

History can sometimes be a battleground in the atheist-christian “wars”. Old Testament history, the life of Jesus, or the misdeeds of the church or individual christians can all become arguments that sceptics use to provide reasons to not believe.

But not all the arguments are based on good history, and one atheist feels strongly about this.

Atheists and christians – does it have to be war?

January 8th, 2017

I have several times blogged on how christians and atheists relate to each other on the internet, because I think courtesy is better than rudeness, and attitudes on both sides can be improved.

So I was interested in christian author Benjamin Corey’s thoughts on this.

Converting an HTML site to WordPress

July 28th, 2016

This page in brief

For years I had a self-coded HTML website with a blog attached. Late last year I made the decision to make it entirely built on WordPress, which necessitated converting about a hundred HTML pages to WordPress pages, and solving quite a few problems along the way.

I am not a professional coder. I am moderately proficient in HTML and CSS, and have a rudimentary understanding of PHP (the language WordPress is written in) and WordPress. If you are setting up a WordPress site, or converting to a WordPress site, and have similar skills (or lack of them), these notes may help you.

But readers who aren’t interested in the mechanics of WordPress may gracefully bow out now!
