The College of Magic in Cape Town held their Annual Stage Contest on Saturday (August 21). The outcome of the contest would determine who would be allowed to take part in the Western Cape Junior Magician Championships, to be held in the Baxter Theatre on September 19th.
Friend Bertus and I attended the event, and it was a total blast – magic is alive and well in Cape Town.

prophets & magic
I love magic. Not the silly kind that the degenerates believe in, but the conjuring kind, legerdemain with a deck of cards. Not only is it fun, but its also engaging intellectually.
When performing a good card trick, you amaze and surprise your audience, because the seemingly impossible happened before their eyes – it's magic! A trick is engaging precisely because it cannot be explained in terms with which the viewer is familiar.
One of my favourite effects plays out like this. I present an ordinary deck of cards and shuffle the cards thoroughly. I then hold the deck out towards the audience member, in full view.
"You're familiar with cards, right?" I ask, as I hold up the top card. "Please tell me what this one is."
"That's the Jack of Spades," she says (or whatever it is).
"Good," I say, "lets put the Jack back on top of the pack," which I then do.
I bring the deck even closer to her, saying, "Now watch this carefully..."

Saturday, August 28 – "Awesome Universe: How to reconcile the Big Bang universe and evolutionary processes with belief in the God of the bible."
This unlikely revelation will be made by Dr Michael Jarvis during a one-day seminar at the Fact and Faith Centre, 10 Berg Street, Wellington, from 09:00 to 16:00. Entry is free, and so is the coffee.

MESSENGER, NASA's "mission to conduct the firts orbital study of the innermost planet", is in orbit around the Sun and positioned to study the elusive planet Mercury. A few months ago, the space craft looked back to Earth to capture a lovely view of our planet together with the Moon.
If you haven't seen Mercury itself yet, now is a good time – soon after sunset, look for the planet low in the west, where it shares the twilight with Saturn, Mars and brilliant Venus.

quote
via JP
“I don't know if I'm the right person to be doing jokes about religion. In the last few months I've become religious, I've started believing in God and creationism and intelligent design, and the reason that I now believe in God and creationism and intelligent design is because of Professor Richard Dawkins. Because when I look at something as complex and intricate and beautiful as Professor Richard Dawkins, I don't think that could have just evolved by chance. Professor Richard Dawkins was put there by God to test us. Like fossils. And facts.“

Here's a rash of silliness that isn't going away soon – cell phones cause cancer. Or microwave ovens cause cancer. Or [insert device of your choice][append "radiation"] causes cancer. Instead, read this month's feature article before forwarding silly e-mails. Be careful: computers cause cancer, too.

Crescent Moon
From Wednesday until the week-end (May 19-22) watch the beautiful crescent Moon after sunset as it passes by Mars, Regulus and Saturn.
Aim your binoculars at the Moon on Wednesday evening and look just 5° below the lunar crescent for the delightful Beehive open cluster (a.k.a. Messier 44).
