- I saw a list of 100 Words Every High School Graduate Should Know. I looked at the graph of a couple of words that I did not know. (There were some words whose meanings I was not sure of but I probably would have guessed them if I had a few alternatives like in Reader's Digest. But I had no idea about these two words.)
- I saw a post about the best movie quotes of all time and looked at the trends of some of the movies (not the quotes because I am not sure how to handle the punctuations).

Some random thoughts
A couple of passages in two books struck a chord in me. The first passage is from Why Zebras Don't Get Ulcers:
An overabundance of information can be stressful as well. One of the places I dreaded most in graduate school was the "new journal desk" in the library, where all the science journals received the previous week were displayed, thousands of pages of them. Everyone would circle around it, teetering on the edge of panic attacks. All that available information seemed to taunt us with how out of control we felt - stupid, left behind, out of touch, and overwhelmed.
I got this feeling many times. In school, the library was this wonderful place which had splendid story books that gave you hours of pleasure. Then you go to college and the library will be filled with journals and books bearing intimidating titles. Serious People will be poring over these books with great concentration. Was I intimidated much? You bet! I will also try reading these books but will not be able to get past the first couple of pages.
There will be whole books on topics that you had thought had been adequately covered in one paragraph in the textbook that you had been using. There will be a rack with the ominous sign 'New Arrivals' where new books with strange titles will keep arriving and disappearing every week. I will wonder who read these books and survived. (There are people who do incredible things. I saw a list of The 100 Most Beautiful Words in English and the first word itself I did not know, among many other words. It is disheartening, I tell you.)
The other passage is about the Nobel laureate Subrahmanyan Chandrasekhar in E=mc2: A Biography of the World's Most Famous Equation:
Subrahmanyan Chandrasekhar was renowned for keeping a calm exterior, but internally: "I am almost ashamed to confess it. Years run apace, but nothing done! I wish I had been more concentrated, directed and disciplined." At the time of this lament he was twenty, and it was but one year since the sea journey where he'd peered into the catch-22 from E=mc2, which, along with other work, would ultimately lead to the understanding of black holes.
When I read books on evolution and astronomy, I often think how the authors know so much. At the end of the book there will be a plethora of books and articles listed as recommended reading. I will wonder when they got time to read them and more importantly, assimilate them. As Mortimer J. Adler said, " In the case of good books, the point is not how many of them you can get through, but rather how many can get through to you." And they also have to spend time on a day job. Did that guy called Isaac Asimov really exist? He wrote so many books on so many diverse subjects that I wonder when he slept. And I start thinking like Chandrasekhar: 'I should not have wasted so much time.' As Kushwant Singh says:
Over the years I have discovered what enormous energy silence creates, energy that socializing and useless chit chat depletes. You have got to train yourself to be alone. You have to discipline yourself to follow a slavish routine.
A major difference is that Chandrasekhar had the thought at 20, I had the thought at 40. What is it that Jimmy Connors said about experience? " The trouble with experience is that by the time you have it you are too old to take advantage of it."

More communication snafus
When I read about mondegreens, I realised that I also had been stumped sometimes by such auditory glitches but unfortunately I cannot remember any, except for the confusion between 'about' and 'above' which happens frequently. I will frame a sentence containing 'about'. I will dictate 'abo..' and Jaya will guess 'above'. I will hear it as 'about' and blink affirmatively. When the sentence is over, Jaya will stare at it in incomprehension and I will wonder what was so complicated about it. When I examine it, I will realise what the problem was and make the necessary correction.
Dictating mathematical notations could cause problems. Once I wanted to dictate a2-b2 = (a-b)(a+b). I began : 'a square...' and immediately ran into trouble. Why? That was because Jaya started wondering why I was telling her about a square when the problem had nothing to do with squares or rectangles or any other shape. After much rolling of eyes, pulling of hair (figuratively speaking), stiffening of muscles and cough induced due to frustration, Jaya will guess what I was trying to dictate. I had thought that I would be able to solve the problem in fifteen minutes but here I was having just got started. I will realise later that the confusion could have been avoided if I had dictated 'a power two minus b power two' or 'x square minus y square'.

'You won't understand'
I remember Freddie Widgeon, who was once chased onto the top of a wardrobe by an Alsatian during a country house visit, telling me that what he had disliked most about the thing was the indignity of it all - the blow to the proud spirit, if you know what I mean - the feeling, in fine, that he, the Heir of the Ages, as you might say, was camping out on a wardrobe at the whim of a bally dog.It was the same with me. One doesn't want to make a song and dance about one's ancient lineage, of course, but after all the Woosters did come over with the Conqueror and were extremely pally with him: and a fat lot of good it is coming over with Conquerors, if you're simply going to wind up by being given the elbow by Aberdeen terriers.

It only adds
There is an anaesthetic of familiarity, a sedative of ordinariness, which dulls the senses and hides the wonder of existence. For those of us not gifted in poetry, it is at least worthwhile from time to time making an effort to shake off the anaesthetic. What is the best way of countering the sluggish habituation brought about by our gradual crawl from babyhood? We can't actually fly to another planet. But we can recapture that sense of having just tumbled out to life on a new world by looking at our own world in unfamiliar ways.
The genes of an elephant or a human, like the genes of a virus, can be seen as a Duplicate Me computer program. Virus genes are coded instructions that say (if they happen to be parasitizing an elephant): 'Elephant cells, duplicate me.' Elephant genes say: 'Elephant cells, work together to make a new elephant, which must be programmed in its turn to grow and make more elephants, all programmed to duplicate me.' The principle is the same. It is just that some Duplicate Me programs are more indirect and longwinded than others.
To see a world in a grain of sand,And a heaven in a wild flower,Hold infinity in the palm of your hand,And eternity in an hour.

What is it like to be 'locked-in'?
The main lesson of thirty-five years of AI research is that the hard problems are easy and the easy problems are hard. The mental abilities of a four year-old that we take for granted - recognizing a face, lifting a pencil, walking across a room, answering a question - in fact solve some of the hardest engineering problems ever conceived ... As the new generation of intelligent devices appears, it will be the stock analysts and petrochemical engineers and parole board members who are in danger of being replaced by machines. The gardeners, receptionists, and cooks are secure in their jobs for decades to come.
