Every number is interesting.a) The number 1 is interesting b) Let's hyothysise that "n" is the first uninteresting number. But the very fact that we have suggested it may be uninteresting, paradoxically, makes it interesting. So the first possible uninteresting number must be at least n+1 c) Since 1 is interesting (a) ... 2 must be the first potential uninteresting number. But 2 is interesting (by rule (b)) so by rule (a), 3 must be the first potential uninteresting number. d) Repeated application of the logic of (c) will lead to the conclusion that all numbers are interesting. The same can be applied to pictures. I show you a picture and you say "that's interesting" and we step though to show that all pictures are interesting A picture paints a thousand wordsHere are three interesting pictures. Would anyone like to say a thousand words about any of them?

It's called proof by induction.
Assumme n is true and then prove true for n +1. Then it's true for n n+1 etc.
Not very well put but a question on it helped me get my OU Maths Foundation Course exam pass.
Modified to correct

No. 1 is obviously a road/rail access point (near Severn tunnel?)
Interesting points.
Road Acess is down hill from gates straight onto the tracks. Main line is not protected with a barrier. Danger of runaways fouling the line.
Are there any warning lights for a train approaching?
Gates are not very high climbable?
The railway is electrified no visable height warnings or portal on road. Presumably used by road/Rail cranes.
No 2 is interresting becuase it's two train working at Cardiff with trains of two diffenrt TOCs▸ sharing the plaform.
No 3 is interesting because only Methyr is in Welsh and English. Although which one is which I need to look up.

No.1. The signalling concrete cable route is only burried in the road surface. Not very good practice, as it should be in a protected piped route with inspection chambers each side of the access road. No.2 is Cardiff Central station. What, platform sharing without any mid-platform signals/stop boards.....

The black text is English and the cyan text is Welsh. Interesting that the black text "Troed-y-Rhiw" is in Welsh which in English is "Foot of the Hill" Abercynon does not translate well but could be derived from "River confluence of the offering" or "Mouth of the hound"

No 1 is the Pilning side emergency services access point for any incident within the Severn Tunnel. A former colleague of mine was a retained fireman at Thornbury and would come in and narrate tales of a shout during the night (an exercise) and his crew were the first appliance there despite having to wake up, dress and get to the fire station, fire up the vehicle and get to the emergency services assembly point and the retainers won the race. This was after the now defunct Avon CC closed the fire station in Pilning. My colleague, well he was the driver.

An interesting inconsistency... In the station name, which is the same (Welsh) name in English and Welsh, it's in black, suggesting the English form is 'dominant'. In the directional arrow, for the Abercynon direction where there is no variation between English and Welsh, it's in cyan, suggesting the Welsh form is 'dominant'.

The emergency track access ramp shown in pic 1 is accessed via a substantial gate not shown in the pic. The roadway from the access gate leads to a lay down area which is just to the left of the barrier at the top of the ramp. Track access would only be made during possessions and I suspect that the reason there isn't a barrier at the bottom is to allow speedy access in the event of an emergency. The main access gate will have a sign detailing where you are, lines on site, mileage, line speed and direction of travel. It should also have relevant info about the OLE▸ . The cable route you see was probably original so rather than cut and replace the cables through a ducted route they were lowered and protected. It's been a long time since I've been there so going from memory. The original access for the tunnel portal was via a set of steps, you knew you'd climbed up and down those. I remember replacing all the tunnel telephones and their associated cables, I walked the tunnel from end to end 3 times in one shift keeping an eye on the lads doing the work. I can also remember going out with a couple of scientists who wanted to look at the rare creatures resident in the tunnel water pools, these guys were super enthusiastic but not so when the first pool we came to had a perfect size 10 boot print in the middle of it.

Abercynon does not translate well but could be derived from "River confluence of the offering" or "Mouth of the hound" I think you're over-translating here. Abercynon is at the mouth of the River Cynon which runs down the Cynon Valley (not surprisingly) and is where it meets the River Taff, which runs down from Merthyr Tydfil and beyond. The railway from Cardiff via Pontypridd also splits here - one branch to Aberdare (where the River Dare runs into the Cynon) and the other to Merthyr. Abercynon was also once known as "Navigation". Trevithick's railway from Penydarren Ironworks terminated here, giving him access to the Glamorganshire Canal. So the location has an honourable railway (and industrial revolution) history.

Da Iawn, Welshman. All over Wales “Aber” exsits. In fact there are many more than generally known, Cardigan being one. It is Aberteifi in Welsh as it is on the mouth of my home river the Teifi.

Happy teenage times - and more recent times too - at Abermaw. And Thank you for the "Scenic Trains" link this a.m., Informan.

Interesting that Welsh keeps the Greek/Latin root for the word for “hound” or “dog” but English restricts this to “canine” and the like. In fact, nobody seems to know where “dog” comes from. It just suddenly appeared and seems unrelated to any other European language.

It just suddenly appeared and seems unrelated to any other European language. Wouldn't it more interesting if both English and Welsh had "random" words? Most words did derive from earlier ones, and common words for common things are the most likely to have ancient origins and be similar (though not always obviously) in many languages. A word without antecedents is less likely, so two lnaguages with them independently is very unlikely - which should be interesting. (To some of us, anyway.)
