Did 2 whole miles!!

Somewhat emboldened by the one mile run yesterday and day before, tried to stretch myself and did a two mile run today. Still kept the run slow. Was able to finish out without the calf muscle pain coming back.

I have to isolate the cause for the original injury – whether it was the quick buildup of miles in September or the new shoe I was trying. (For now, I am using an old pair of shoes).

Trying out an ambigram of my name

As I mentioned last night, I learnt about “ambigram”s while reading a book by Alex Bellos. For our purpose, we can say an ambigram is a calligraphic writing such that when you hold the paper upside down, you get the same writing!

That is quite an achievement! I looked up the internet and found some free ambigram generators. I am trying to learn how to write an ambigram of my own name.

It does get your mind to think in a different way when you are practicing every stroke. Basically, you have to think how that stroke will look when you hold it upside down and is it going to build up the other letter you need to build up. (The letter that is as far from the end as is the one you are writing from the beginning). So while writing my first “R”, I have to do it in a way that if I turn it upside down, it should look like the last letter “y” and I have to draw the exact opposite of how I wrote “R” in the end to write “y”.

You will see that after half an hour of trying, my output is still amateurish. You can even spot the mistake I made in the last letter. I also realized that I need to get a thicker nib from the calligraphic pen set than I did this morning.

Early afternoon sun

Took half a day off from work to enjoy the gorgeous sun this afternoon. Was on the terrace of Rootstock with Sharmila. Met our old friend Abby there too. The topics of discussions varied widely from Ghenghis Khan to “Is time a real or imaginary concept?”

Scripts of five different languages

After storm Zeta and learning the Greek alphabet, I had this crazy idea – albeit not too crazy as far as my ideas go – what if I tried to learn the script of another language?

I remembered, while in Mongolia, I had great difficulty reading their language. So, figured maybe I should try some language with a Cyrillic script. Settled down on Russian. The language has 33 letters and 10 vowels. Eventually got the hang of the upper case and lower case. The pronunciation was a different thing though. There are lots of sounds that are not there in English language (some are there in my mother tongue Bengali). A lot of the letters look like English but have nothing to do with the corresponding English letter. I am still struggling with the difference in pronunciation of “Й” and “ы”. All in all, was interesting to pick this up. I am going to keep trying to identify the letters in words and pronounce them thru the end of this year.

So, with English, Bengali and Hindi (based on Devnagari script), that makes it 5 different scripts for me. (I am not counting German and Spanish since they are too close to English).

Thinking of picking up one more. Tamil has a very different script. At one time, I had taught myself the script (back in 1985). Maybe I will brush that one up…

Puzzles in a Singapore class

Yesterday, my blog reminded me of this incident from seven years back when my friend from Singapore – Jyotsna – had pointed out that puzzles from my blog were being discussed in the classes of Singapore. And she asked me to post more.

So, here goes a fairly interesting puzzle:

Imagine a pharmaceutical company in a race to find a cure for coronavirus. It has come up with 1000 chemical formulas as potential anti-virus vaccinations. Those chemical formulas are sitting as solutions in 1000 different beakers in their lab.

However, only 1 of them is effective. In fact, it is supereffective. Even a small trace of it injected in a rat’s body will extinguish the virus within 7 days. The other 999 are of no use. They also know that you can mix those chemical formulas up and the resultant concoction will retain all the properties of the original formulas. Put simply, in a combination of solutions, if you have even a little of the effective formula, the whole combination is supereffective. Else, any combination of those other 999 solutions is totally useless.

One catch is that the pharma company has exactly 7 days to win the race to a vaccination. Which means it gets only one time to inject rats with the various combinations of the chemicals and see what happens by the 7th day.

As if that was not enough, there is way too much demand for rats – apparently lots of pharma companies are trying to do experiments for the vaccination.

Finally, they have to find out the exact solution with the effective chemical formula – there is enough manufacturing capability to make only one of those solutions in a scaled manner.

What is the minimum number of rats the company has to procure to conclusively prove which one of the chemical formula is the ultimate solution against the virus? How would they do the experiment?

Survived a mile of run

To test out how much the calf has recovered, I gingerly put in a mile of very slow run. In fact, it was split into two runs of half mile each with two more miles of walk. The good news is that the leg held up fine. Did quite some stretching after that to take no chances…

Here is to hoping the long road to recovery has started…
