Have always been a little puzzled by the speed of light and time compression for space travel thing. Since speed is relative I never got why the return trip couldn't be considered that the rocket was stationary and the earth moving towards it very quickly so cancelling out the differences in time. It came up again in a book I was reading the other day. The next book I started on was Paradoxes by the physicist and TV presenter Jim Al-Khalili.
So I had a peek at his web site and there was a "contact me" button. So I did and asked him about speed of light thing and space travel thing, I also mentioned I was reading his book and enjoying it. Didn't really expect any answer.

Amazingly next morning I had an email from him. It said:

Its not a symmetrical thing as the acceleration and deceleration undertaken by the spaceship and not the earth breaks the symmetry. By the way this is covered extensively in chapter 8 of my book which you are reading ...

Pat slaps head ....

Nice of him to reply though.

Yeah, I always knew I was wrong just couldn't find it explained anywhere why :)
I think you'll find it's a bit more complicated than that.

Isn't it something to do with spacetime stretching, so symmetry is routinely broken (and this explains why distant starlight appears to break the conservation of energy but doesn't if you consider that spacetime continues to expand)?

Honestly, I don't know why this stuff took Einstein so long.

Speaking of B&M, the dynamo buffer battery I put in a cupboard after PBP 2015 hasn't been used since and is probably dead.

And dead it is.  I put it in circuit & gave the wheel a spin: light stayed off. Battery out of circuit & spin again, light comes on.  Oh well.

Lithium-ion cell protection circuitry will probably trickle-charge until the voltage is in spec, before coming to life (if the cell isn't too far gone).  Suggest you ride PBP with it again and see if it starts working...

I would dearly love to, believe me.

I'll try and knock together some kind of connector and put it on a USB charger.

ETA: I've got it hooked up to an old 9v battery (exp Jan 2001) which is still delivering 5.8ish voles, and sitting within smelling distance on my desk just in case.

ETA': That's rubbish: charging current is around 2 mA.  Recommended max is 1.5 A.

I decided to shorten a pair of trousers using the iron-on web stuff that I have used successfully before. Went very well until I realised that I should have turned the trousers inside-out before starting. Doh!

I shortened my trousers that way for a job interview in the 70s.  When I came out I headed post-haste, still in my interview duds, to the clinic where my wife was about to give birth. While she was in the throes the tape job gave way.  The first thing the theatre nurses did after my daughter was born was to fetch sticking-plaster for my turn-ups.

Didn't get the job.

For some reason I'm crap at out of office voicemail and on email. Did them all today, my old work mobile didn't do the thing where the keypad wouldn't display which leads to a long pause after I finish. Remembered to press # all good

Except I'd done them all retuning to work

I can either time travel or off work for 11 Months

Mega div

Went for a rough, boggy bimble on local hills.
Stopped to take photos with phone at one point. Shoved phone back in bag.

Get home - no phone in bag.

I *probably* shoved it part way in and it fell out when I put bag on back - it was so windy I had trouble getting rucksack back on my back.

That was when I was standing in knee-high heather.

Likely location of dropped phone; over an hour's walk away at a minimum. But it could have been anywhere on a very rambling, pathless walk.


This is super-bad, as my phone is used to verify access to work systems.

That worked very well for my daughter's phone after she dropped it in some long grass on a walk. It was only a few hundred yards from where she was when she noticed its loss.

The location given by that is at least 3 km out

Or, when taking a phone in a pouch with a leash, they need to be not such an effing div and actually use the leash.

Took the rear wheel out one of my bikes as dismantling the derailleur for a thorough clean. Due to mudguard need to deflate tyre a bit

Put all back together and went for a brew. Oiling chain and think hmm tyres a bit soft must have had a visitation. Thankfully just before taking it out to fix i noticed the valve was undone and remembered why

That thing where you go for a wee and realise you flies are already open, and you are left trying to work out when you last had a wee, and where you've been since then.
Admission.  I'm actually not that fussed about cake.

Taking out a wall and window. There is already a beam above, this used to be a garage door-sized entrance.

Cut the screws holding window in place. Hmm won't move. Took out all the blockwork to the sides - still won't move. Took out blockwork below. Surely?  Yes, with a nudge. Bastard heavy for its size, mashed my fingers. Ow

Managed to roll up the sheeting I had outside (with several beams clamping it to provide strength. Tied up with rope.

Ok, work done. Lower it. Untie one end. Untie other, holding beams. I'll step down off ladder and go to the middle . . . Whole lot slips through fingers, 4.8m of 4x2 smacks me in the head and sends me flying. Ouch. Gingerly prod skull checking for bleeds. Nothing major.

Idiot.

And the divvery continues. I'm on a roll, folks!

Cycle in to Stornoway - only about 16km away but I'm going shopping at it isn't flat.

Rush to library. Lock up bike. Erm, hang on, my bike lock key isn't on this keyring. No problem, I always keep the spare key in my tool pouch.  Why won't key go in?

That's the Abus key. Not much chance of it working in a Kryptonite lock. You absolute arse.

So I did bare minimum essential jobs, that didn't mean leaving bike alone for long. People are pretty good around here, but it is school chucking out time and teenagers are teenagers everywhere.

Guess which idiot left his glasses within the dog's easy reach...


Glasses by citoyen, on Flickr

This is one of the two new pairs I bought just over a month ago. He's already had a go at the other pair, but fortunately didn't get further than chewing the end of one of the arms.

Luckily, they're cheapos from Glasses Direct, which lessens the pain somewhat.

I took advantage of the new customer offer from Glasses Direct, which means I got both pairs with change from £20.

Price is not the main concern anyway - I just can't read without glasses now, and since reading is a rather fundamental part of my job, they're quite important to me.

Although I'm actually more worried about the possibility that the dog has eaten bits of broken glass - I really can't afford a vet's bill right now...

Just follow the trail, that'll answer the second question.....
