Rainbows do not actually exist.


They are an Optical Illusion caused by a Prismatic effect of the sunlight on raindrops.


Rainbows viewed from High Altitude Aircraft can be seen as complete Circles.


So sadly they do not have Ends and hence no 'Pot of Gold' :(


Nice Pics though. ;-)

Hey thanks for that DulwichFox - could you make sure you pop round on xmas eve and give my kids the hard facts about Mr Claus?


;-)

Lol, Keef and legalbeagle.


We saw the double rainbow from the front of a bus on the way to Deptford, and at one point the end of the main bow appeared to be over Canary Wharf.


Was amazing how it got brighter and brighter.


I love rainbows :) Would like to have seen it over East Dulwich, so thanks for the pix!

No Problem.


Should I explain about Tooth Fairies as well. ;-)


Trouble is, Who does eat the Mince Pie and drink the Sherry. ?


Where does the Sixpence under the pillow come from. ?

I did think the rainbow was beautiful, hence my earlier posting. However I don't think doubble or even triple rainbows are that unusual-if you look carefully they are often there. However I think this one was brighter than usual, perhaps because the quality of the light and the placing of the dark clouds
In truth light is white, but when refraction of light in water takes place, the human eye perceives the entire gamut of colours.


This is completely incorrect. Just because it's on the internet doesn't make it true.


Different colours are just different frequencies of light. The water vapour disperses the coloured components of white light at different angles. There is no illusion.

Some people believe that Rainbows have magical healing properties, and it is said that faith healers use the colours of the rays separately to heal different ailments. Even the pharmaceutical company's believe this to be true and colour their medicines accordingly. It is also believed that a rainbow is sent by god to help ease the pain and suffering and happens after tragic incidents.


I don't believe any of this mumbo jumbo myself.


Jacko.

Oh dear, this has become mumbo jumbo couched in unreasonable deductions based on experiential evidence.


Jeremy is quite right, our Basque friends do not have the inside story on rainbows. Refraction does bend light waves of different frequencies by different degrees. A rainbow is not an illusion. Blue light, with it's smaller wavelength will be bent (scattered) more than longer wavelength red light. It's the same reason the sky is blue (all that blue light scattered all over the place) and sunsets are red (because all of the shorter wavelength colours have been scattered by traveling through so much atmosphere leaving just the red to travel to your eye).


Pills have a different colour not because colours are 'healing' but because the mind responds differently to colour signals that are entirely natural in their provenance.

    • Couldn't agree more with the frustration. I avoid it like the plague but made the mistake of picking up a parcel a couple of months ago and it took them 20 minutes to find it. This was after queuing for an hour. All the pickup parcels were just in a massive heap with no order or organisation so they manually had to search for everything. Bizarre and deeply annoying as if run well it could be a good asset to the Post Office and of course the community. Also, very much agree with the point re not taking it out on counter staff as it must be a terrible and demoralising environment to work in.
    • It's my understanding that it's private delivery companies such as Evri that have the post office as a delivery point so you can't redirect those parcels to Peckham SO as that's only for Royal Mail but, yes, probably worth trying a different drop off point. As you say a lot of the queue is for people dropping off and picking up parcels to and from Evri and other companies, kind of like a private sorting office, and while there is clearly a huge demand for this service, the post office was never designed for the number of parcels it is now required to deal with resulting in long queues and lost or hard to find parcels.  This messes up the efficient provision of other core PO services including cash/bank services now there are no banks in ED. I think this one office is being required to do too much for its size. 
    • I think one of the problems with Lordship Lane is the sheer number of people using it to return items as it is now one of the only Evri parcel return points - I have been in there a few times (with an Evri parcel return I hasten to add) and everyone seemed to be doing the same. Either that or posting bags full of small sized packages each one that took a few minutes to deal with! I agree - it's definitely not working but I don't think the Post Office really cares as the business is on it's knees and I suspect many of the poor staff having to endure it are too.
    • There are a number of reasons for the long wait time and improvements can be made.  The counter staff is inexperienced.  They all started work at the PO in November 2025. There are 5 work stations.  On a normal day there are only 2 of the 5 stations open for service.  On a good day there are 3 workstations open.  On one day just before Christmas there were 4 open.  In all the decades I have been using that PO there has never been an instance of all 5 windows being open. If they could aim for having 3 of the 5 windows open and serving customers at all times that would make a huge difference.  2 windows is not enough. Recruitment and training are problematic.  Sickness is a problem.  I think it is a very stressful work environment.  Please do not complain directly to the counter staff.  They are powerless. I use the PO every day.  6 visits a week.  I run a small business.  I can no longer use LL - I have to travel to a different PO.  Because I visit every day I have had plenty of time to observe and IMO the one service they need to stop immediately is allowing people to collect deliveries directly from the PO.  Why, because that location is not equipped to deal with it.   Here is an example of why it needs to stop.  Today the queue was long with 2 windows open.  One customer was collecting a package.  The package could not be found.  One of the 2 serving staff spent just under 15 minutes (yes, I timed it) looking for the package.  It still wasn't found and the customer left empty handed.  For 15 minutes there was only 1 member of staff attending to the queue - the other was looking for a package.  This happens a lot - I promise you this happens every day. If you are an ED resident considering having your packages redirected to Lordship Lane then please don't.  They cannot efficiently provide this service.  Redirect to the Peckham Sorting Office instead.
