#140 & #325, Alak @ IIT MADRAS

Encumbered forever by desire and ambition
There's a hunger still unsatisfied
Our weary eyes still stray to the horizon
Though down this road we've been so many times

The grass was greener
The light was brighter
The taste was sweeter
The nights of wonder
With friends surrounded
The dawn mist glowing
The water flowing
The endless river

Forever and ever

I ask for forgiveness

This is always an important day, for the reasons esoteric. It is an unusual and, I think, unusually important day today. I may not be quite as easy with my words today as I have been in years past, and I was up rather late last night thinking about and praying about what I ought to say today. So if you will forgive me, I will do my best to say what it is I want to say to you. First, I want to say to all of you that, as you might imagine, I have been on quite a journey these last few weeks to get to the end of this, to the rock bottom truth of where I am and where we all are. {Inspired by Clinton}. I am an outcast. I am a Ganguly in the Indian cricket team, a Beckham in the 98 world cup English team, satan of the Hebrew apocrypha, a Judas Iscariot who betrayed Jesus, a Brutus who brutally killed Caesar, a Tony Clifton or a Andy Kauffman for sick anti-humor, a Vanunu in Israel. I cannot do it like others. I wish I knew what it takes or have I lost the zeal, the vigor. I am not an old junkie. Why doesn’t it flow into my mind, tickle my synapses, hurt my conscience and make me do it. Is it time constraints or so it seems. I wish I could envisage in it “a floydian seduction” or “a seraphic, elysian green innocence” or “a soccer’s adrenaline rush”. I wish I could join communities that I forget after I join; I wish I could read others scraps and peek into their privacy; I wish I could scrap, read as flirt, unknown people; I wish I could don a false identity other than keep in touch with buddies. My soul wanders beyond boundaries, to uncover a reason for me to become a part of this community, which means-“the holy meeting place” in Turkish and “orgasm” in Finnish.
I ask for forgiveness.

There's Plenty of Room at the Bottom

I would consider this the best prediction of science now and to come. He envisages science concurring to the constrains of the future technologies. This man seems to have known all of it. From my course PHY598 and some handouts..here is a bief interpretation of his predictions

We would just have to press the same metal plate again into the plastic and we would have another copy.
This is the PDMS stamp technology developed by Whitesides.

We can reverse the lens of an electron microscope in order to demagnify as well as magnify.Ha ha E-beam lithography.Modern lithography is used to produce posters, books, newspapers, packaging, credit cards, CDs.

A source of ions, sent through the lens in reverse, could be focused to a very small spot.-Focused Ion beam Lithography.

Now, instead of writing everything, as I did before, on the surface of the head of a pin, I am going to use the interior of the material as well--3D storage not yet practical in this form. Layered structures common in IC manufacture and layered materials

you simply evaporate until you have a block of stuff which has the elements--
Molecular beam epitaxy for layered materials; layered structure of integrated circuits.

Consider any machine – for example, an automobile- and ask about the problems of making an infinitesimal machine like it.
MEMS it is. Some sub micron MEMS.

What could we do with layered materials with just the right layers?
Here he is refering to layered semiconductors and magnetic multilayers.

It is possible to emit light from a whole set of antennas , like we emit radio waves.---Is he fucking refering to Nanophotonic materials.

We could use, not just circuits, but some system involving quantized energy levels, or the interaction of quantized spins.
This dude predicted quantum computing and spintronics.
