Geek, Dork, and Nerd

Geek: A person who finds interest in quirky, out-of-the-world, uncommon stuff, and becomes fanatically obsessed with knowing every detail of it.

Dork: A person who is socially clueless.

Nerd: A person who prefers intellectual activity to social activity.

Which one are you?

Dancing Lady

Thanks are due to the naughtiest guy in class for this. It's not spectacularly amazing or anything, but just pure fun, and really, really, time consuming.






Which direction is this lady dancing in? She is definitely spinning, and she is spinning backwards (for herself). But is she going clockwise or counterclockwise?

There are probably hundreds of such trick images circulating the internet, each one perhaps equally interesting, because each probably presents a different trick, or a different way in which our mind plays tricks on us. Of course this particular one has no answer, because depending on how you see it, she can be moving in either direction. If you try hard enough, you can see both types of spin, and you can even train yourself to make her change direction at will. It's actually really simple: you just have to figure out that critical point of her spin, from where your brain starts to pick up on the direction of her motion. If you happen to start looking at her only from that critical point onwards (achieved easily and simply by a quick shutting and opening of the eyes), you can make her change direction. It's important not to preserve the image of her motion in the mind as you're trying this.

If you received this in a chain mail or forwarded message over the internet, you probably also got a lot of text about left brain and right brain and their relative abilities and so on and so forth. While all of that is probably very interesting, it is perhaps best left to the explanatory capabilities of Wikipedia or some other reliable encyclopedia. For the moment, concentration on enjoying the illusion. This is magic at its best -  the magic of the human mind.

Cheat The Prophet

Just found a very likable quote all over again.

"The human race, to which so many of my readers belong, has been playing at children's games from the beginning, and will probably do it till the end, which is a nuisance for the few people who grow up. And one of the games to which it is most attached is called, "Keep to-morrow dark," and which is also named (by the rustics in Shropshire, I have no doubt) "Cheat the Prophet". The players listen very carefully and respectfully to all that the clever men have to say about what is to happen in the next generation. The players then wait until all the clever men are dead, and bury them nicely. They then go and do something else. That is all. For a race of simple tastes, however, it is great fun."

I'd recommend reading the book from whence it came as well: The Napoleon of Notting Hill, by G K Chesterton. It's available for free from Project Gutenberg, and I've just started it. It seems it'll be a good read.

Deadlines Matter To Us!

A firm of surveyors, in the mood for some whacky fun, took an extremely fat book and went out to study the reaction of people in various professions. 

The doctor looked through the book, pausing to note intriguing passages, and declared his opinion that it would take him six months to complete a study of the book. 

The lawyer skimmed through it, flipping quickly through the pages, and said it would take him a couple of months to plough through it. 

The manager glanced at the book and its title, and averred it would take him a week or so to get through it. 

The engineer didn't even look at the book. "When's the exam?"

Many thanks to the two lovely ladies who told me this story.

Colourblind

"Don't try to understand bureaucratic logic. Trust me, you don't want to," said my wise friend Marcus Licinius Crassus. He told me the following story.

A steel company in a small central-eastern state in my country, once wished to set up mining operations there. They penned a letter and sent it to the Department of Administrative Affairs to seek the required permissions. The Department flipped the moment they received the letter. Reason? It was in green ink.

"Oh no, our department correspondence and work is carried out only in red and black ink," said they, and so the forwarded the application for a second opinion to the Ministry of Interior Affairs. And those guys flipped out too. Reason? "Green ink is used only by the top guys in the military."

So they forwarded the application to the Ministry of Defence. And again, those guys flipped out! Reason? "This is nothing to do with us or our department! It must go back where it came from!"

And so the application found it's way back, over the course of eight months, back to the Ministry of Interior Affairs, which sent it back to the Department of Administrative Affairs, which sent it back to the steel company, stating that the application needed to be in line with the law passed two months back, stating that all applications and forms must henceforth always be penned in blue or black ink.

I don't know about the steel company, but Reynolds, Add and Cello must have made a fortune in blue and black ink since then.

Warning: True story. Oops, you already read it. :D

Viva la Project!

What have you done in this project?
Nothing, really.

Why do we need hybrid systems?
Environment friendly, you big bad smoking chimney!

Why do we combine solar power with wind power in a hybrid system, of all the renewable sources we can use?
Reminds me of the beach. Soak in the sun, with a cool breeze flowing... Gets me started, man!

What have you done in one year?
Watched movies, went on a trip, drank chai, got drunk, ate lots of nice food, celebrated my birthday, what more do you want to know, you sneak!

What is the efficiency of solar system/wind system?
Should be good, else we wouldn't use it.

What have you actually simulated?
How the thing works, you doof. Why not just read the damn report?

Why have you used voltage signals in the simulation, when a power system deals with load?
Coz that's what's possible in the goddamn software! Man, talk about being a prof...

Why have you chosen LabVIEW instead of Matlab?
Coz that's what my guide told me to do. Plus, it has a nice view... isn't that what it's supposed to be? Lab-View?

What are the voltage ranges we can deal with in this hybrid system, ie what is the load you can supply?
Whatever load you want, you build a big enough machine, and it'll supply. Talk to Homepower.org, they deal in installation info.

What is the use of your project?
Getting a grade so I can get out of here. Also perhaps some kid could copy it and get a grade too.

What machine is used in a wind turbine system?
The one that's used in all of them.

How can you increase the efficiency or power output of a hybrid system?
Umm... throw out the garbage on time? So that the system doesn't have to waste time doing it.

How cost-effective is a hybrid system?
Not much. I spent all my time and energy on this one, and that other idiot spent only 10 grand on his... and got a better grade! Talk about unfair!

The Tortoise and the Hare - Extended Version

One day the hare was getting bored. He decided to challenge the tortoise to a race, thinking it would be fun to tease the tortoise about how slow he was. The tortoise accepted the challenge, and on the day of the race, things happened according to the old fable. The hare slept off in his arrogance, and by the time he awoke and reached the finish line, the tortoise had already won.

The hare was extremely unhappy. He knew he was the faster animal, so the next day he challenged the tortoise again. The tortoise couldn't refuse, of course. As expected, the hare, having learnt his lesson, stuck to the race and won it.

Now the tortoise was the unhappy one, feeling that his hard work had come to nought. He challenged the hare to a third race the next day, which the hare couldn't refuse. The hare started running, thinking that the tortoise was stupid as well as slow, since he couldn't possibly win. But suddenly he was brought to a standstill, and could go no further. He had reached a deep river, and there was no bridge to cross it. He remained stumped at the riverside, while along came the tortoise, who swam across the river, reached the finish line and won the race again.

What was the outcome of this? The hare and the tortoise became friends. On land, one was the powerful one; in the water, it was the other. There wasn't any point in striving against each other.

Life's like that, too.

Story related by my favourite teacher in college.

Electrical Machines

I hate the subject. Shameful, since it is part of my chosen branch of study (but that's excusable, since I didn't take it up by choice (but still now so excusable, since I did not chuck it and take up something which was ultimately better for me to have done (but never mind now, and I probably should stop this coz this thread is going on too long!))).

At any rate, at least the textbooks are funny sometimes.

Sample this for instance. Excerpts from Electrical Machines by Vandana Singhal and whoever was the other chap who wrote the book with her:

Chapter 5: Introduction to Synchronous Generators
A synchronous machine has a rotor and a stator. (Wow! I didn't know that at all! As though other electrical machines have something different altogether.) The rotor of this machine always moves at synchronous speed. (Isn't that hard to guess now?) It may be a synchronous generator or a synchronous motor. (Amazing! So we can't have a synchronous transformer!) A synchronous generator receives mechanical energy from a prime mover to which it is mechanically coupled and converts it to electrical energy. (I see. So what do other kinds of generators do?)

AAAAAAAAAAAAAAAAARRRRRRGGGGGGHHHH! I'm supposed to give a test to determine if I know this crap???? :P

Are You Going To Scarborough Fair?

Are you going to Scarborough Fair?
Parsley, sage, rosemary and thyme,
Remember me to one who lives there,
For she/he once was a true love of mine.

Tell her to make me a cambric shirt,
Parsley, sage, rosemary and thyme,
Without no seam nor needlework,
And then she'll be a true love of mine.

Tell her to wash it in yonder dry well,
Parsley, sage, rosemary and thyme,
Which never sprung water nor rain ever fell,
And then she'll be a true love of mine.

Tell her to dry it on yonder thorn,
Parsley, sage, rosemary and thyme,
Which never bore blossom since Adam was born,
And then she'll be a true love of mine.

Ask her to do me this courtesy,
Parsley, sage, rosemary and thyme,
And ask for a like favour from me,
And then she'll be a true love of mine.

Have you been to Scarborough Fair?
Parsley, sage, rosemary and thyme,
Remember me from one who lives there,
For she/he once was a true love of mine.

Ask him to find me an acre of land,
Parsley, sage, rosemary and thyme,
Between the salt water and the sea-strand,
For then he'll be a true love of mine.

Ask him to plough it with a lamb's horn,
Parsley, sage, rosemary and thyme,
And sow it all over with one peppercorn,
For then he'll be a true love of mine.

Ask him to reap it with a sickle of leather,
Parsley, sage, rosemary and thyme,
And gather it up with a rope made of heather,
For then he'll be a true love of mine.

When he has done and finished his work,
Parsley, sage, rosemary and thyme,
Ask him to come for his cambric shirt,
For then he'll be a true love of mine.

If you say that you can't, then I shall reply,
Parsley, sage, rosemary and thyme,
Oh, let me know that at least you will try,
Or you'll never be a true love of mine.

Love imposes impossible tasks,
Parsley, sage, rosemary and thyme,
But none more than any heart would ask,
I must know you're a true love of mine.

I love this song. I simply love it. For days now, I have been able to sing nothing else, listen to no other song. This is the full text of one version of the song, though it is considerably shorter in the version sung by Simon and Garfunkel.

But more than the S & G version, I love the instrumental rendition by Lori Pappajohn. On the Celtic harp, accompanied by flute, percussion and violins. Totally amazing... and the best part is, unlike other pieces of music, though it keeps on playing in my mind, having it in the back of my head doesn't irritate me. It keeps me cool, calm and collected at all times.

Meat!!!

For this I thank the one with whom I've been friends before birth. Sorry girl, for ripping the link off your blog, but believe me, I give you full credit for spreading the cheer!!!

They're made out of meat... by Terry Bisson 

Enjoy!!!

2.5 Diggers? I Say It's Possible!

Textbooks can say a lot of stupid things as well, besides the sensible stuff. Of course, very few textbooks actually go to the extent of giving wrong stuff (unless they're sponsored by the State Government!), but there are some priceless examples which are technically correct, but just can't be allowed all the same!

Take for example, Organic Chemistry, by P.L. Soni. It lists out the uses of paper:
1) As tissue paper
2) As napkins and toilet paper
3) As gift wrapping paper
4) Envelopes and packaging
5) Cardboard
6) Sandpaper
7) Heat insulation
8) Writing and printing books
9) Printing newspapers
And yes, they are printed more or less in this order!

More examples to follow as the process of discovery continues. Watch this space.

2.5 Diggers? Not Possible!

Of late, I've been fortunate enough to be reading scientific books, both the general variety and the textbook variety, and I've been reading good books. The most striking quality of these books is the way they have been written, informative enough that they grasp attention, and yet light hearted at the appropriate spots, so that they don't lose that attention. And as for the textbooks, even good textbooks are of two kinds: the kind that just drones on about the subject in a clear, complete, and concise manner, and the kind that does the same thing while ensuring it doesn't get monotonous.

There aren't too many examples I can quote here. I don't have that kind of energy. But I do want to record those few examples. I don't want to lose track of what I've realised. It's really cute when you're reading the thing with a serious mind, and then the author puts in an appropriate line to make you smile. That really allows you to enjoy the whole process of reading the thing.

Sample this for instance. This was taken from "Engineering Electromagnetics" by Hayt and Buck.
"It is philosophically satisfying to have the most general result and to feel that we are able to obtain results for any special case at will. However, such a jump would lead to many frantic cries of help, and not a few drowned students."

Another quote from the same text. "We are faced with a choice of many methods by which to evaluate this component, and we shall use but one method and leave the others as exercises for a quiet Sunday afternoon." (!!!)

And yet again. "Since one coulomb of electric flux is produced by one coulomb of charge, the inner conductor might just as well have been a cube or a brass door key rather than a sphere, and the total induced charge on the outer sphere would still be the same. Going one step further, we could now replace the outer sphere by an empty but completely closed soup can. Q coulombs on the can would produce W = Q line of electric flux and induce -Q coulombs on the tin can.
"If the soup were a perfect insulator, it could even be left in the can, without any difference in the results!"

For those who aren't exactly physics freaks, my apologies. It's amazing, the kind of things you can learn. While dealing with the physics of time, pure mathematicians (theoreticians all of them) have gone through the pain of creating worlds (in theory) where you can travel back in time. The entire story is given in "The River Of Time", by Igor Novikov, a book on quantum principles and how they affect time, for the layman. Quote:
"These worlds are generated by solving systems of equations of general relativity. It appears that the general opinion has been that these solutions have no connection whatsoever with reality, despite being of great interest for studying the structure of the theory itself. Everyone knows from one's acquaintance with school arithmetic that the formulae of a correct theory can give incorrect - 'physically meaningless' - results. It is sufficient to insert inappropriate numbers into the conditions of a problem, for arithmetic to generate an unacceptable result: say, to excavate a hole in the ground of volume 30 cubic metres in 4 days, with each digger capable of digging 3 cubic metres per day, you need... 2.5 diggers. Results of this sort made more than one pupil cry."

Thinking leads to chaos! And how! A brilliant example on how to understand entropy, given in the same book. I loved this one. I quote:

"The heat released as a consequence of 'memorizing' makes the ambient air warmer and thus increases 'chaos' (entropy) of the Universe. It is always larger than the order introduced into the storing device when information is recorded. Stephen Hawking gives the following example. If you learned by heart each word in a book like this, your memory would record about two million bits of information. This is the measure of how much order was created in your brain. However, reading the book, you have transformed at least a thousand calories of ordered energy stored in food into disordered heat dissipated into the atmosphere. This increases the chaos in the Universe by about twenty million million million million units of data. This is ten million million million times greater than the gain in order in your brain, and that only if you do remember everything in this book..."

The Ad Hoc Chronicles!

You know one major reason why college is different from school? It’s because of the people who teach you whatever you’re supposed to learn. In school you’re faced with professional experienced hard core teachers who know what they’re doing (or at least put up a good show of it). In college, you come across this whole new exciting category of people, called ad hoc lecturers (or ad hocs, for the purpose of convenience). They generally tend to be graduates or post graduates fresh out of their education and onto teaching for a trial period, or for a bit of experience. And they are exciting, for several reasons.


First of all, and most obviously, the fact that ad hocs in general tend to be of the category that can send your hormones racing. It happens for both guys and gals. Nobody minds the dullest subject, if what you get in return is visual ambrosia. The entertaining part of the scene begins when the ad hoc in question gets an inkling of the existence of the ambrosia factor, and begins to ponder the real reason behind the strong attendance of so many devil-may-care, canteen-is-heaven young people! Especially when chronic back-benchers race for the first bench, and look like half-wits while the lecture is proceeding.


Next but equally, ad hocs are great favourites because of the bloopers and blunders they make while trying to educate their audience, who often have the upper hand, but prefer to enjoy the drama being played out. You get the one-liners… and then you get the masterpieces as well. It’s one thing when someone uses the definite article in English grammar (that means the word ‘the’) in a sentence, as though sprinkling cheese on pizza, (for example, ‘this is the not the correct way to do it, and it will the fetch you the bad marks in the exam’) but it totally beats all resistance to exasperation when the entire class is trying hard and unsuccessfully to explain the fact (to a totally unconvinced young teacher) that one mole of water does not quite contain two molecules of hydrogen and one molecule of oxygen! And then who is going to forget the lovely time they had, when every query with regard to Cochran boilers was met by an everlasting, never-changing negative!


Okay, I’m not implying that ad hocs are idiotic or useless. There have been several lovely moments in the lab, when you’re sitting down frustrated because the idiotic piece of machinery you’re supposed to be fooling around with is not working, yet you’re not worried, because you have three or four ad hocs conferencing over the situation, and arguing amongst themselves on what the problem is and how it is to be solved!


The most wickedly funny part is the fact that ad hocs cannot too easily be recognised as ad hocs. I and a couple of friends traveling home in the train once met this person and got talking to him. One strapping young friend of mine began to blast our college faculty, and the ad hocs in particular, and one specific ad hoc, only to be told by the other guy, quite obviously, that he himself was an ad hoc in the same department in our own college. There’s a colloquial saying to describe this kind of situation. “Waat lag gayi…”


Okay, but besides all the brickbats that they get, you can’t forget the bouquets that they deserve. Because who else is going to patiently reset the apparatus in a highly sensitive experiment every time you upset it, who else will show you how to do it right for the practical test, who else will tell you secret tips and tricks to make that stupid machine work, who else will bail you out with the exasperating ordeal you face in the viva later on, and who else will help you out with all the crazy and even insane doubts you face at the last minute before the final exams? Your friendly ad hoc teacher, of course!
