Dafli Wale Dafli Baaja

Remember the story of the Noorie cassette from last week? That Papiya-di had lent to me and Avijit? Well, guess what was on the other side of the cassette? “Sargam“!!

I remember loving each and every song from that movie – Dafli Waale, Hum To Chale, Koyal Boley, Ram Ji Ki Nikli, Koyal Boli, Kahan Tera…

To complete the memories of that cassette from four decades back, Sargam vinyl record was the choice for this evening…

From the bartender’s corner – Tuxedo

This drink’s name has a fascinating root. Back in the 1880s, a private members-only club called Tuxedo Club started in the planned community of Tuxedo Park in Orange County, NY. This is the same club that gave us the menswear called “tuxedo”. Around the same time, a new cocktail was served at the bar in the club. As you must have guessed, it was called Tuxedo. This is a nearly 140 year old drink.

Vodka, Dry Vermouth, Maraschino Liqueur and Orange Bitters. (There is a variation that uses absinthe too)

Here is another problem to be solved

Now that we have solved the temperature problem in Chicago, here is another one from San Francisco.

[Errata: Looks like I have completely forgotten my physics – Sound is longitudinal and light is transversal – it is about which way the wave is moving and the particles in the wave are moving.

However, my original question remains – although I cannot remember the terms now – a ray of light goes straight but sound disperses in all directions – like the pool analogy. So, how does this work?]

Last week, I was in San Francisco and as his is wont, Matt Moore invited me to go for a walk with him by the waterfront and discuss business issues. While walking around Pier 15 enjoying some nice coffee, he showed me something. It is basically a set of two parabolic metals facing each other about 50 yards away. Each has a small stool to sit on. Matt asked me to go sit on one and he sat on another. As you can see in the picture.

Some of you might have guessed this, I could distinctly and loudly hear what he was saying. It felt like he was just six inches behind my head and he was talking to me from there with a slightly louder than usual voice of his.

For the next few minutes, I showed off my Physics to Matt by eloquently explaining how we were sitting in the focal points of the parabolas and how his voice was hitting his parabola, going then in a straight line to my parabola (geometric property of parabola if you remember) and then my parabola was putting all that on to its focal point which is where I was sitting. You would have seen the same in microwave towers, large telescopes etc. I do not know what Matt thought but I thought I did a good job.

Two days later, I realized what an idiot I was. I was telling Sharmila about it and then half way thru, I stopped cold. I realized that everything I said to Matt was correct but only for longitudinal waves – you know like microwaves, light etc. But sound is a transversal wave. It spreads out in concentric circles (like if you throw a stone in still pool). Those sound waves from Matt would have emanated as concentric circles and then after some of them hit the metal parabola, they would start out as more concentric circles from the point of incidence (where it hit the metal). Then where is the question of focus and all that in an ellipse?

But I experienced it myself.

How do you explain that?

How do you explain this?

It is bone chilling -8F (-22C) right now here in Itasca. But it will slowly warm up as the sun comes up. That part I get. But look what happens after the sun sets. The temperatures keep rising thru the night. Of course, there is no sun around. Lake Michigan water cannot be that warm – after the last few cold days – to explain that.

How do you explain that?

Football score puzzle

In American football, any drive can end with the following points – 0 (ball turned over), 2 (safety), 3 (field goal), 6 (touchdown with failed point after or failed two pointer), 7 (touchdown and successful point after) or 8 (touchdown and successful 2 point conversion).

Assuming no team scores more than 50 points in a playoff match (there has to be a winner), what are the different legitimate combinations of scores that a match can possibly end with? (e.g. a game can end 14-2 but can never have a 27-1 score).

Noorie

It was 1983 or 1984. My best friend Avijit Bose and I had gone to our friend Kaushik Samanta’s house. Kaushik’s elder sister – Papiya-di – introduced us to a new cassette she had bought – Noorie. At that time I did not know but it was already a 4-5 year old movie. I had never heard of the movie but loved the songs. One of my earliest introductions to Qawwali (albeit the Bollywood version) – “Aashiq ho to aaisa ho“. Loved “Chori Chori Koi Aaaye” too!

A few weeks later, Papiya-di lent that cassette to me. I remember Avijit and I listening to the songs over and over again at our place!

Almost 38 years later, those were the same songs I listened to again. (one more of the vinyl records I got from the Kolkata trip this time).

Book Review – “Through the Language Glass”

By Guy Deutscher

Why the World Looks Different in Other Languages

I forget which book, but somewhere I had read that Russians have two different words for what we club as “blue”. And they “see” two different colors if you showed them the whole spectrum of “blue” whereas we see one. That had given rise to an interesting question in my mind – Does our perception of the world get affected by our mother tongue (the language we learn to express what we perceive by) or do we all perceive the same thing – we just express it differently?

During Covid, downloaded a book after quite some research – Through the Language Glass and was fascinated by what I learnt.

Found out that Russians are likely to find it ridiculous that English speakers think of two different colors – “siniy” and “goluboj” – as one color – blue. They fail to understand how we do not clearly perceive two different colors. We just don’t see how these are different. If pressed, we will admit, one is simply “deep” blue (think deep ocean color) and the other is “light” blue (this about the Caribbean waters). Conversely, we are likely to find it ridiculous that the Ovaherero people in Namibia do not see the two colors – green and blue as two different colors. We wonder – “What’s wrong with you? How can you say blue trees and green sky?”. It is not like they do not register in their brain as two different colors – it is just that they do not see what is the big need to call them two different colors. Just like we don’t see the need to label deep blue and light blue differently in normal life.

Grammar is yet another area where how we think of events get influenced deeply. Take verbs for example. In English, you have to convey to the audience the “tense” of the verb. You have to pass on the perception of if the event happened in the past, present or future. But you do not need to pass on the perception of the “person” (subject) who for example “walked”. In Arabic though, both the tense and the person is embedded in the verb. In Chinese, neither is embedded. The language grammar influences what you think are the important things to be conveyed during aa conversation.

Different languages force the speaker to pay attention to different aspects of the world every time you try to speak or listen. As an interesting (and somewhat extreme) example, there are Amazon tribes (like Matses) where you cannot just say “Rajib ran by our street”. The language will force you convey either experience (did you see him run) or evidence (he left his water bottle by your gate) or conjecture (he always runs by our street) or hearsay (your neighbor told you he ran by your street).

The most fascinating one is how certain folks (scattered all over the world – Polynesia, Mexico, Bali, Nepal, Namibia, Madagascar) have no concept of left or right. Just the four cardinal directions. Imagine that. Regardless of where they are, they always have an accurate sense of what is North!!

Even gender biases show up in how we see the world. Time and again, an experiment has been done – almost always with the same results. A bunch of Spanish folks and a bunch of German folks are shown a picture of a bridge and asked to describe it in adjectives. The Spanish – for whom bridge is a masculine noun (“el puente”) – use words like big, dangerous, long, strong, sturdy, towering… and the Germans – for whom bridge is a feminine noun (“die Brucke”) see it as beautiful, elegant, fragile, peaceful, pretty and slender!

There are many more such interesting examples from different languages. Eventually, the author answers the question that I had – although apparently, the answer has been settled for good only in the last half century – the language you speak in absolutely biases you regarding how you perceive the world.

Highly recommend this book if this is an interest area for you.
