Not done one of these for a while.

Pretty Moth

Visible to anyone in the world

This rather pretty insect perched on my mint is a Brimstone moth, one of the Geometridae, so-called because their caterpillars are inchworms that progress by 'looping'. The animal anchors its rear legs, stretches the front part of its body forward, obtains a grip with its front legs and pulls the back of its body up behind it.

A BIG number

Visible to anyone in the world

These numbers have the property that if you double them you get a perfect square

2, 8, 18, 32, 50, 72, 98, ...

And these have the property that if you multiply them by 3 you get a perfect cube

9, 72, 243, 576, 1125, ...

Some numbers are in both lists; the smallest is 72 and

2 x 72 = 122, 3 x 72 = 63.

It's not possible to extend this and find a number n such that 2n is a square, 3n a cube and 4n a fourth power. However it was asked on Quora what the smallest number is such that n such that 2n is a square, 3n a cube and 5n a fifth power. Alon Amit showed the answer is 215320524. In full this is

6810125783203125000000000000000.

I decided to extend this to the next prime number, 7, and found the smallest n such that 2n is a square, 3n a cube, 5n a fifth power and 7n a seventh power is 21053140584790. This impressive number evaluates to

150462810922326152710290228433686961530697356776074449373600141938371053848189980134027578261857302770024765419887333164323078738017254430529707573248000000000000000000000000000000000000000000000000000000000000000000000000000000000000

which has 234 digits.

I think we can continue and add 11, 13 etc. but at this point I ran out of steam!

Airplane Memento

Visible to anyone in the world

One of the planes a friend crewed in times gone by has been taken out of service and will be recycled but people who worked on her in the early days were offered a piece of the plane as a memento. My friend chose a window and brought it to the pub where it attracted great interest.


Here is the plane it came from. It was window 6 on the left hand side.

Type - Airbus A319-111

Serial Number - 2385

Engines - x2 CFM56-5B5/P
