You do not need to know cricket to answer this quiz

Most of my friends in the USA may not be aware that World Cup Cricket is going on. There are 10 countries participating. (unlike our World Series Baseball where we just invite Canada in).

Each team will play the other 9 teams resulting in 45 games and then the top 4 go to semifinals and then of course, the final.

I was looking at where different countries stand today. This is how the chart looks. Country name, points and the result of the last five games, starting with the most recent.

Study that table carefully.

In any column, you would expect 5 wins and 5 losses, right? 10 teams playing each other – 5 winners, 5 losers. That is how you would expect every column to be. And that is how the third and fifth column indeed are. But the first, second and fourth column have 6 wins or losses and 4 wins or losses.

How is that possible?

Somebody explain this to me

I had gone in to Starbucks for about an hour. When I come back, I see this.

Notice carefully – there is a cobweb strand connecting the side view mirror of the car to the rear bag of my motorcycle.

Here is my question – how did the spider travel near horizontally in the air? It could not have gone to the ground, crossed over and then climbed up. There was no wind to talk about either.

That is an amazing achievement. And something I cannot quite figure out how it managed to do.

The mail van roof problem – one more step forward

But no where close to the solution. You might remember the original observation and some progress to this problem from my prior posts.

This evening, I sat down in our balcony with Jay Jay and a cocktail when I noticed that there was a crew of two people in the post office yard. And in a few seconds later realized that they were painting the vans. Especially the roofs.

I got excited. Maybe finally I will crack this problem?

But there was something very incongruous about their painting. They had not covered up the windshield!! I was wondering how were they preventing the white paint from getting all over the glass?

The curiosity and the possibility that I might finally know the answer to the roof rust problem got the better of me. Put Jay Jay inside the house and walked up to those guys from a side entrance.

The two gentlemen could not have been more surprised by my question!! A very interesting conversation happened then.

First thing, I learnt is that they were not painters. They were simply cleaning the vehicles. And that was not rust – it was mold!! They see this mold in all the mail delivery vans. And they agreed that it always forms on that particular edge. But neither had any clue why.

Oh! so close!!!

As I was walking out, I saw a USPS gentleman trying to put something in another van. I walked up to him and made friends with him. He first apologized that our house looks into the USPS yard. I assured him that it gives me endless joy watching the vans and trucks come in and the workers milling around.

And then I asked him the all important question. You know what he said? He said that from the upper deck, it had noticed that pattern too but never knew why. And he had not spent much time thinking about it anyways. Then both of us stepped into one vehicle to see if we could see anything from the inside. Absolutely no clues!!

He did teach me something. He explained that these were 25 year old Grumman LLVs. And that USPS is switching over to newer vehicles by Oshkosh. Came back home and read up about it. There are fascinating facts out there about these vehicles.

But not a word on why mold grows on only one edge of them.

The endeavor continues!!

We are getting closer to solving the problem

Do you remember the last two curiosity questions I had posted on the postal vehicles? The one about why one side of the postal vehicles’ roof is always rusted and the other one about why some of them have steering wheels on one side while the others have it on the other side?

Well, hearing the responses from you all on the second one, we might be closer to solving the first one.

For the second, we have logically concluded that the steering wheel is on the “wrong” side only if the vehicle is meant to deliver mail door to door. That makes sense. The mailboxes are on the right and the driver does not have to get out every single time (not to talk about seat belt on and off). The ones that had steering wheel on the “right” side clearly was being used to transfer mail between post offices or purposes as such.

This morning, while having tea in the patio, I tried to see if the roof rusting matched a pattern I was wondering about.

LO AND BEHOLD!! IT DID!!!

Look at the picture. There are three vehicles that have no rusting on the roof. Look closely at those vehicles – they are the different looking vans that are NOT used for door to door delivery. And look at the door to door delivery vehicles. Each one of them have that pattern.

So, this HAS to do something with the requirements on a vehicle for door to door delivery. I know they do not have any HVAC. The windows are always open for constantly flinging the mail or putting the mail in the mailbox. I have even seen table fans in these vehicles to cool down the drivers.

So, what is it about windows being always open that might have something to do with the rusting?

This is where I am starting to think that Nick Kules might be on to something… that the way the drainage on the roof is designed might have something to do. Could it be that there are ridges so that after a little rainfall or water accumulation, the water does not drip down the window and potentially wet the mail? And that is why the stagnated water rusts out the roof?

Then why not on the driver’s side also?

I HAVE to crack this problem.

Need you all to pitch in with your combined imagination and analytical powers.
