A BIIIIG Number

I've just noticed the length of the URL for a comment I have just made:

blogger.com/comment.g?blogID=6586801766217114148&postID=4403352031319564287&page=1&token=1278774745713_AIe9_BEAh9qzrqZpvMiTtBzZQNfNgTllEdGXbRIhww7y87iHJEnCVuQ_FgQvYFtOAoDWEsEzfDUrJQ7PxkFiCQvuDKjLE73MXveCEz99uLlVxd1l6ln1hbT8lbK25DbhoupHfCLRj4pRVt-st7acZL0rraXyNjKyOpA0c_7hD1yssgV7y2K1fw5U4LSp6ywEQqabi5liHGT_xnnQPG23X3LWfTv6_zdynIrR3IbWZbGJJqtnWkGhmsovQ8qrBW21Dyzm_HiEWcgseJp5ywsqUwGKg-bylEpGbOQNV2wOhAsw1dzMvsJxUC7DhHhPrHlNkhX6Q9EraFz_1_rijKyg5OqVWnmuKo8C8wqpQ6_QRg_RBECs_HJL7y1sjIT-N5PrFSndZBQpylCKg4MsvEqEA5V21jfk5XjB-bvROvUpVikPwgwko-awlkFbRfhBQDvWSe2ZN5ykReKWgmAeMsxXrQj_m1lYLJbHjfIEDBzkRRP7uLtrUhsjxUD1td2FnCy2cd-9F3M4dIwoGPc59HEfCSwWTuFgT0NafumCPkp_4coNhuyuDkqEcxiWifUIN5WUqL8bGIlNXFBq3YWp80Juo1lskBFefwTE-w-aHw8tIifLf87Yo1Rk0xpDAZdJnA1RK-m_3CpcXlqusyTB3npbP-wuU8Cf8chItg

Any mathematician will realise just how many possibilities there are for all the variations of this URL

There are 52 alternatives for every letter used (upper and lower case) and of course ten for every number.

On my screen at the moment there are over 50 characters in every line.

There are ten lines

That's a number 50 X 10 ie 500 for all the characters here.

Each one has say 50 possibilities so that's 50 to the power of 500 possibilities

By comparison 10 to the power 6 is a million

This figure is in the region of 10 to the power 1,000

If each unit represented a centimeter .

I bet the length would be in the region of many light years.

Are there really this number of comments being made on Google's blogs alone?

Looks like there's a lot of redundancy present!

The URL will often be longer than the comment - what a lot of computer storage is being wasted!

The token part is not relevant, it's just used by blogspot to track your session on the site

I'm going to be like a five year old who constantly asks why:

So why is the token part so long?

Because you did not use "tinyurl" google it and use!

Geoff Dellow said...

Thanks for your explanations but i still want to ask

Why?

Why the upper and lower case letters.

Whenever I see something a little quirky, I wonder "Why ?"

I can think of some other quirky questions but it's time to cook something to eat and go to bed!

Geoff Dellow said...

In fact, here's another one.

I'm cooking some eggs . 4 minutes in boiling water.

Does it matter that the water only comes only half way up the eggs?

Will the convection currents inside the egg cook it all the way through?

time to get back and find out!

No wonder you've got a headache. Sometimes in life it is best to simply accept what is. Unless it needs changing, of course.
