isi lurking + an unrelated problem

here is a sum that held me in due to oversight on my part.it has got only one twist- thats all!
here goes-


imagine a rubber string, fixed at one end, is streched linearly in a horizontal plane so that the free end always has a velocity 'v0'.if an insect at the free end starts moving towards the fixed end with velocity v1 , at T=0, and initial length of string is L, find the time at which the insect reaches the fixed end.
my question is that wat shud b the min value for v1/v0.

sorry for for the accccute wording though- cudnt help it.

u know i already feel like reading for college- i feel exhausted with this standard syllabus already.
if u ppl hav applied for isi-bstat admission,discuss in this thread.

Flap Flap ... Times Back

So, ppl ... wonder where i had vanished all this time, been on some very distant time travel into the depths of future. Nah. busy with IITJEE. well tats gone so now i can do some thing closer to my heart. This is what i have been working on.

ORNITHOPTERS

Seems a very far fetched name. But wat lies within is even more weird. Ornithopter as d name suggests is 'flight like birds'. flapping wings. no propellers. The key difference between an ornithopter and an airplane is that the driving airfoils move up and down instead of rotating. For both the airplane and the ornithopter, most of the lift results from forward motion through the air. In the ornithopter, lift is produced by the flapping wings, often in conjunction with some additional fixed wings. Birds likewise use their body and tail as a fixed lifting surface.

Why Ornithopter ?
My sudden intrest in ornithopters can be attributed to the recent air mishaps- crashes. i was very upset. the current air plane designs are over a century old. fixed wings. high forward thrust, some thing new is required. Ornithopters are better in following ways:

1. Very high maneuverability
   
2. low noise
3. high lift
4. good fuel efficiency

Ornithopter isnt a new concept. the first ornithopter was built in early 1900s !! manned flights on ornithopters hav also been achieved. but considerable work needs to be done before u and i can ride one.
Now wat am i working on? am on a fold wing type model which will have a very strong downstroke, enabling it to 'climb'. i will write the details one i have made a successful model. But there is one problem. This isnt a basic science topic and hence i cant take it up in KVPY program. :(

Well then, i think 3d matrices will be good enough for the summer project ...
waiting for ur responses (and refueling my time machine)

PANIC!!! New Blog Look

First of all, I'd like to apologize my absolute disregard for all the hard work Rash and Twish did for the site. I thought I could play around with the site so that the comments page would be a bit wider (since we tend to have long comments), and just change the look a bit.
As a result I made a huge huge mistake of not saving a template backup. I thought that there would be a rollback option at the stage, but it seems that there wasn't. Again, I'm so so sorry that I screwed up all your hard work, and I'm desperately hoping that you have a few back up. If not, tell me what all you had, and I'll put in the work to make sure that its back.

I hope you like the new look. I feel its a bit brighter, and easier to navigate. If you've any objects, comment about it.

The KVPY Summer Programme: Discussion

As I laid out in the 'above' thread, this is the discussion thread. Please abuse...

The KVPY Summer Programme

All of us have been caught up in the exam, and I think its time for us to get back to the task at hand, the KVPY Summer Programme. I'm sure that each of us has some ideas if what to do in their bulbs, but really a lot of us haven't the least idea on how to do that. Then again, it could just be me, but I'd like to see you come out and prove me wrong, and then help me out.

So this is how it works, this first post is for each of us to list out what we plan to do, and possibly where we plan to do. You can be as descriptive as you like, and you can write a cute love story between you and quantum physics if you like. But, you get only one post, and you can edit it however much you like. (Copy the entire text and delete your old post if necessary). I want it like this so that we can keep it clean. Do post what you've done, plan to do, etc.

Now, there will be a second post following this one, where we shall discuss as freely as we'd like one what was written in the first post, as well as talking about penguins.

I hope you all pitch in and we're able to create enough volume to help each other out.
