Richard Dawkins and P.Z Myers In Conversation

Friday, June 10th, 2011

Last night the BHA hosted  and armchair conversation between Richard Dawkins and PZ Myers.  After roughly half the audience had entered the room, a handful of protesters pushed their way in and onto the stage. Initially mistaken for religious loons, they eventually made it clear they were protesting Dawkins’ involvement in the New College of the Humanities and the existence of the college itself. While the death of free education in this country is a worthwhile thing to protest, the protestors definitely chose the wrong forum for the protest last night.

The audience were there for a free-thought debate / conversation, so were never going to take kindly to being shouted down at. They completely alienated themselves with their attitude – no matter what arguments they had, nobody was prepared to listen.

They were eventually turfed out by the police & campus security. The talk then began, but with police at all exits standing by to repel invaders.

As the talk moved from exobiology towards atheism, two other protestors got up from their seats, stood before the stage and tried to read out some questions or a speech. I may be wrong, but I gt the impression they were there to protest the anti-religion element of the talk (both RD and PZ being rabid atheists). The two protestors were quickly escorted outside after RD announced several times he would take their questions at the end.

When both speakers were asked what they would like the future to look like, there was a mutual agreement that they would like the word ‘Atheist’ to be meaningless. Both look forward for a time where you don’t have to state your disbelief in something, for the word to be as pointless as a ‘Leprechaunist’.

The night ended with the BHA Chair wrapping things up, suggesting we all join the BHA and thunderous applause from the audience for the speakers.

A darker than usual morning at this time of year

Sunday, January 2nd, 2011

Going back to work on the 4th of January might be enough to darken anyone’s spirits, the mornings are dark enough, but come the 4th dawn will be even darker for us here in London. A partial eclipse will have the moon covering up the rising limb of the sun, the uncovered portion will still be below the horizon at sun-up (08:06am).

Seeing as it will almost certainly be too overcast to take photographs and I’ll have no clear view to the low horizon anyway, I’ve prepared some simulations of what you would see (or I would photograph) were conditions perfect (with no atmosphere glare either).

The start of the eclipse as you'll not see it from East London

The Sun will clear the horizon by 8:15, but a good portion of it will be eclipsed by the moon.

9am

Just as you’re starting work, the sun will be high enough to clear low roofs and trees, you might get to see a chunk missing from it if you’re outside or near a window.

But it’ll probably be too overcast.

All over
9:30, and the sun is definitely high enough to see now, but you’ve missed all the action.

It’s a shame hardly anyone in London will see this eclipse, because it’s one of the best London will see for a long time. The centre-line passes right though London, skirting the west-side of central park in East Ham, passing right over Ilford station and just clipping the eastern edge of Valentines Park.

A fun toy for working out where the eclipse is visible is this map from NASA. The next total solar eclipse visible from London isn’t until June 14, 2151, so armchair eclipse hunters have a bit of a wait.

Something’s crawling in my hair.

It’s a flying ant day here in London. The parks and pavements have been covered in large, brownish, winged & wingless females looking for somewhere to start a new colony.

Some of the smaller males are also around, looking for a place to die. Their job of fertilizing the females is now over.

Of course, all this flying protein is far too good a resource to waste,

You can wait for it to come to you…

At a visit to the LWC today, I saw a heron stalk, catch and eat a mouse-thing. Luckily I had the camera.

Now I have an xray machine to play with at work, I can take photographs of the insides of things. I shall make full use of this. Here’s an old transistor to start with.
