Bells

Whitechapel Bell Foundry
Something like thirty years ago, I was on a bus with my grandfather passing The Whitechapel Bell Foundry; he told me a little about the place and promised to take me for a visit when I was older. Three years ago, I bought a ticket for a tour the following year, then forgot to go. Yesterday I finally toured the foundry with around 25 others, I was probably the second youngest in the tour party – very few other the others were below retirement age.

The bell foundry is the oldest manufacturing company in the UK, having been formed in 1570 (and with good evidence that it may date back to 1420 from earlier foundry works in the area). The foundry site on Whitechapel Road dates from 1738, originally having been The Artichoke coaching inn, built c1670.

The tour was interesting and through, we learned the bell-metal casting temperature, 1170 degrees C; the composition of the casting molds, a brick core covered in goat-hair, clay, sand and horse manure shaping mixture (photo); the number of harmonics a modern bell is tuned for, 5 – the same note in 3 octaves and a minor 3rd and a 5th.

At the back of the works, in the yard, a new set of bells and mounts (photo) were being prepared for St Dunstan in the west.To make best use of limited space, the hand-bell workshop and the woodworking workshop are built above the foundry floor. These workshops have rather low ceilings and beams – no one taller than 5’8″ works there. In the wood workshop where bell wheels are made, is the foundry “graveyard” commemorating those that have died while working (no details give for those, possibly an interesting story) and in retirement.

I’d love to re-visit when they actually cast a bell, but understandably they prefer not to have members of the public around when sloshing tons of molten metal around.

DG visited in 2008, around the time I booked my first, forgotten, tour.

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.

Dandelion wine – or – That was Easter Monday

Tuesday, April 26th, 2011

Making dandelion wine is a messy business; First you have to collect ~400 grams of flowers, then you have to separate out the petals:

Messy


Finest dandelion petals (and a few unlucky bugs)


Then boil them all up with sugar, raisins and some orange peel:

Stir and strain, stir and strain


And then hope it ferments into something nice.

glub. glub. glub. (continue for 4 weeks)

Fingers crossed, that in six months to a year, we’ll have some nice wine.
Recipe:
400g of Dandelion flowers, 1kg of Sugar, 150g Raisins, Peel of 4 small oranges, 1 gallon of water. Simmer flowers in water for 30 min, strain off flowers and add sugar, raisins and peel to solution and simmer for a further hour. Allow to cool before removing peel and straining and squashing raisins for their juice. Add yeast and decant to demijohn. Wait.

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.

I dug out an old school book, from way back when I was 8-ish. Here’s a look at the random stuff I wrote about back then.

I was an electronics geek even back then…

And a consummate storyteller.

I hadn’t quite grasped the finer points of evolution though.

And while I now love spiders, I still can’t quite bring myself to look at a centipede without a shudder.
