The wonder ink formula!

Chemistry

My 9th std Chemistry was taken by three teachers. Usha madam went on leave and then Bindu madam took charge. But then the unkind KVS transferred her elsewhere. Finally Devaki madam took over towards the end of the term. The reason I mentioned this is because of one project in Chemistry that Devaki madam asked me to submit. It was nothing special. I made a bathing soap. But the interesting story is what I did with it. Here is the whole story:

I bought sodium hydroxide to prepare the solution for producing soap. I was glad because it was a new chemical to add to my lab. Anyway I dissolved some NaOH into water and then mixed coconut oil and Eau de Cologne into it. After a while the solution solidified into a white substance. I left it for a week and then cut it into pieces. We first tried it as a washing soap and it worked. Then I took bath with it and I was happy because it worked as a bathing soap as well. I took it to school and submitted as my project.

An example of bad handwriting - Mine was worse though

Since time immemorial, my teachers have complained about my handwriting. It hasn’t improved to this day and I am glad that I took writing to my computer so that I don’t have to write on paper anymore. Be that as it may. On the day of submission of my project, I was sitting in maths class and as usual scratching the paper with my shabby “calligraphy”. It was a blunder I committed because one of my friends wanted the exact same pen that I had. I bought him one and then he wanted to exchange the nib since mine was smooth.

After I exchanged the nib, I realized my blunder but still bore with it. In the middle of the class I had an idea. Will adding soap to the ink tank make the writing smoother? To test it, I took a small piece of soap and put it inside the ink tank of my pen and sure enough, I had the most slippery smooth writing experience in my entire life!

Eureka!

But I noticed something strange, the ink was decolorized! Just a faint azure hue remained and it looked as if I was writing with an invisible ink. Nevertheless I continued writing. I went onto the next page and the next page. Then I just returned to the previous pages and EUREKA! The writings were visible again as if it was written by normal ink. Just a little lighter but that was okay! I had discovered something!

I started to show off my new found “invisible ink” which I called “wonder ink”. Later I experimented with pure NaOH to see whether that worked the same way but that turned the entire ink into purple color.

During the beginning of my 10th std, I went to tuition at Paul Manjooran sir’s tuition center. I told him about this discover of mine and showed him this purple ink. He told that this is analogous to litmus paper used in laboratories except that the color code will be in the reverse order. He told that if I put some acid into this solution, the blue color will return. I tried mixing some lemon water into it and sure enough, the blue color came back in. I also found that this experiment works better with Bril brand of ink than Chelpark.

My experiments continued…

Exothermic reaction!

Potassium Permanganate

I was in my 5th grade. Once I asked my dad to buy me Citric Acid and Potassium Permanganate saying that I needed to do some experiments. He bought me the two chemicals. I think probably that was the beginning of real experimentation in chemistry. I had done other experiments as well, like understanding combustion better. But that is a different story.

I started mixing the two chemicals in various proportions to see what happens. The first experiments had a larger proportion of the acid and less salt. Nothing happened. Except that the solution gets decolorized. I even tried drinking this compound just to find that it increased my hunger.

Then one day I had fever and we went to Sanjeevani Hospital at Naval Base. After I returned, I took the cap of a brandy bottle and mixed a larger proportion of the salt and a smaller proportion of the acid and I noticed something strange. The solution was boiling itself. And the cap was very hot. I was wondering what was going on. I told this to my brother. We did it many times but since we weren’t aware of the chemical formulae of these chemicals, we didn’t understand why it reacted this way.But I was exhilarated. I thought that I had found something new.

We tried mixing other substances into this mixture to check how it reacted. I remember the incident in which we mixed kerosene and set the solution on fire. The entire solution burst in an awesome white flame as shown in the image. That was the most spectacular event I had observed so far in our lab. Wow! But the smoke that followed was not very friendly. My brother caught running nose after inhaling that smoke. The experimentations continued in the years that followed……

A note on the Fermi-Hart Paradox!

The Habitable Zone

The Habitable Zone around a star

The future of humanity looks bleak and bright at the same time depending on how we perceive it. If we look around, we may feel that we are moving forward towards a brighter tomorrow. However, if you look up, the thoughts change. The sky on a clear night is one of the most beautiful sights you can get on Earth but this awe inspiring sight brings questions into our minds regarding the bleak future of human race. Whether we are alone in the universe is a question that might give us clues about our own fate in the distant future. We can hope to grow so advanced that we wouldn’t have to look back or we can expect ourselves to fall back and perish. SETI scientists spend their entire lives with radio telescopes pointed at the sky listening to the “cosmic buzz” hoping to find evidence that there is intelligent life outside Earth. The Drake Equation gives different estimates regarding the number of intelligent civilizations outside depending on whether it is an optimist or a pessimist who substitutes the values. However to this day, there hasn’t been any conclusive evidence that there is life outside out planet.

This paradox first postulated by Enrico Fermi and later examined by Michael H. Hart, analyzes various reasons why there haven’t been any intelligent exobiology detected so far.

The Drake Equation – Predicts the number of civilizations in the galaxy

The statement made by the Fermi-Hart Paradox is as follows:

The apparent size and age of the universe suggest that many technologically advanced extraterrestrial civilizations ought to exist. However, this hypothesis seems inconsistent with the lack of observational evidence to support it.

So why is it that despite the size of the universe, we haven’t seen intelligent life outside earth yet? Two corollaries of the Fermi-Hart paradox may give us some clues. They are the Doomsday argument and Von Neumann Probe.

According to the Doomsday Argument, we ask ourselves, Is it the nature of intelligent life to destroy itself?

This theme has been extensively explored in science as well as science fiction alike and deals with an argument that precludes the possibility of a technological civilization with an invariable proclivity to destroy themselves shortly after developing radio or space technology. The various postulated means of annihilation include biological and nuclear warfare, nano-technological catastrophe, accidental contamination, a badly programmed super-intelligence, ill-advised physics experiments or a Malthusian Catastrophe that deteriorates the planet’s ecosphere.

Probabilistic argumetns have bene put forward suggesting human extinction as an inevitable event happening sooner than later. Sagan and Shklovsky suggested in 1966 that either a technological civilization will destroy itself within a century after developing interstellar communicative capability or will master their self destructive tendencies and survive for billions of years.

Thermodynamics and chaos theory may also suggest clues regarding the tendency to self annihilate. As far as life can evolve as an ordered system, it may not create a problem but when it starts with its interstellar communicative phase, the system would probably get unstable and eventually self destruct.

Self destruction is a paradoxical outcome of evolutionary process in a Darwinian point of view. Evolutionary psychology suggests that at a time when humans competed for scarce resources, they were subjected to aggressive instinctual drives like tendency to consume resources, extend longevity and to reproduce which eventually led to a more technological society which may drive us to extinction. Self destruction of a technological civilization, according to Fermi, might be a universal occurrence. Self destruction may not be the only outcome though. There is a remote possibility of the civilization getting back to being non-technological as we saw happening to the Ba’ku people in the movie Star Trek: Insurrection.

A Flying Saucer – An alien craft?

A slightly different question is posed by the Von Neumann probe which asks, Is it the nature of intelligent life to destroy others?

This postulate investigates the possibility of a technological civilization, once it reaches a certain level of technological capability, destroys other intelligence when they appear. This concept has also been explored in science fiction for decades. The causes of such extermination might be expansionism, paranoia or plain aggression. Cosmologist Robert Harrison added a corrolary to Sagan and Shklovsky’s suggestion in 1981 by arguing that given a technological species that has overcome its own tendency to self destruct, it will view other species in the universe as a virus and try to exterminate them. A direct consequence of this argument is the picture of an intelligent being as a super-predator, just as humans are today.

Von Neumann Probe

Just like exploration, extermination of other civilizations can be carried out using self-replicating artificial probes. It is a more dangerous case since even after the civilization that created such probes have died out, these probes will continue to do the job their creators assigned to them. If take this possibility into consideration, then that might answer the scarcity of observational evidence of extraterrestrial intelligence, because either these probes will destroy them, force them to be quiet or force them to live in hiding to prevent detection.

Leaving all these arguments aside, there is still a very high probability that we are indeed alone in this universe. To conclude, what is going to be our future? Are we heading towards self destruction? Is our life and society as ephemeral as that of a mayfly? Are the advancements we make every day in technology actually the nails we are driving into our own coffins? Or are we going to be like the Borgs? I leave this up to you to answer.

When it all began!

It was a warm evening in 1989. I asked a question to my mom about the way the Earth-Sun system works. She spoke about Copernicus and Galileo and the Solar System. She told about how much they sacrificed their lives to let the world know that what the church preached was wrong. I was just five years old but the impression stayed in my mind. Her description of how the day and night occurs was fabulous. She took a plastic ball and demonstrated how the Earth moves. She said that the Earth does not move around the Sun like motorcycle but rather it spins on its axis.Then she spoke about bacteria and as per her description, in “my world”, it was the smallest thing I could imagine. Especially when she told that a single dot can have millions of bacteria in it. But I still thought I could see them. I was seven when I learned from her that there is something called atom. I asked her what an atomic bomb is and that’s how she explained what an atom is and how scientists split it in order to cause Hiroshima and Nagasaki.I was impressed by that. I wanted to know more about it. I remember cutting down a grain of boiled rice using a knife to the smallest possible size and taking it to her saying that I found the atom. She smiled and said that it is far smaller than that. Something which I cannot see.

I was disappointed.

But I was determined to know more. I learned when I was 11 years old that the atom had an internal structure. Long before it was taught in school. I was fascinated by the world of the subatomic and I knew I had to know more.

I wandered around in the school library reading books on it. Fortunately I had a two close friends with whom I could discuss the subject. We used to discuss both the microscopic and macroscopic realms.

I then set up my own laboratory at home at the age of 13 and started doing chemical experiments. I think that is where it all began. The scientist within me was born and the curiosity continues till date!

PS: The titles “Emptiness and Form ” and “The Cosmic Dance” are not mine. I copied it from “The Tao of Physics” by Fritjof Capra. A book that has inspired me a lot.

E vs R?

The Blind Watchmaker by Richard Dawkins

Recently I watched Dr. Richard Dawkin’s 1987 TV Show “The Blind Watchmaker” which is based on his bestseller with the same name. In it, he speaks of a program he wrote to simulate what would happen if a character set is made to rearrange at random or use the principle of natural selection in order to finally form the Shakespearean phrase “METHINKS IT IS LIKE A WEASEL” from Hamlet.

DNA

I obtained the C++ source code of the program from here and ran it. It demonstrates nicely how something can evolve by natural selection. Even though the biological evolution doesn’t know what is going to happen in future as compared to the program, it does try to predict the survival strategy of the the living creature in question and propagate the genes suitable for such a strategy. He further went on demonstrating the same using a graphical program with advanced features.

I recall an incident that occurred few years back. My college was founded in 2002 and mine was the first batch and hence we didn’t have any seniors. But the following year, we started getting new students and hence juniors. There were many of us who tried to rag them but the management was strict about its anti-ragging policies and ragging in the college remained a fun activity than anything serious.

When the third batch came, the story repeated. However the new principal who had taken charge very recently came to our class one day and said:

Passage of Time

I know you will be interested to know your juniors and get acquainted with them and I appreciate that. But I don’t appreciate the way you have chosen to do that. If you look at history, there has always been two processes of development. One is a rapid advancement of a concept to bring forth notable changes within a short span of time. Such a change is called ‘revolution’. There is another way of development which is a very slow and gradual improvement on existing concepts that bring forth lasting changes over a period of time and that is called ‘evolution’. I suggest you follow the evolutionary way of getting acquainted with the new students.” Evolutionary way!

Image of Mutation

Mutation

It is a proven fact that given sufficient time, species change to ensure that their genes survive in the changing environment.  A recent article in Nature says that in every generation of humans, there are at least 100 to 200 mutations happening in the genes. Hence we may also evolve into a new species in another few thousand or million years. But I must add that along with biological evolution, human intellect has evolved too. We see rapid advancements in fields of artificial intelligence and genetic engineering. Also we see human cloning as one of the emerging fields. We humans have become capable of artificial selection!

Let’s pause and think where this is leading us.

Brain Chip

I recall my friend saying: “Our generation is the one that struggles the most. In the past, there was very little to study and you could get any job after your 10th grade. In future, advancement in brain chips will make learning obsolete by creating babies who already possess, at the time of birth, all the necessary information for its survival on the planet!

I admire him for this accurate prediction because it was not based on intuition but on real facts that we see around. Indeed that’s what is going to happen. We will surpass the pace of evolution and start producing a new breed of humans who will be far superior to us in all aspects. If as mentioned in the opening paragraph, a simple program can be made to follow the process of selection, we may even create an artificial evolutionary process by which machines can evolve and finally make the human nature survive through those machines long after the human race has vanished!

Fittest will survive!

The title of the post, “E vs R” as you might have rightly guessed is “Evolution vs Revolution“. The future will be a combination of both. We will revolutionize by conquering and controlling evolution! We won’t be left behind in the struggle for existence. There won’t be any more “the fittest will survive” motto since everybody will be equally fit and we shall all survive together.

Now whether this equality that we try to bring about is in the interest of our existence or not is something we need to wait and find out.
