random useless thoughts (lewis carroll / douglas adams / roald dahl style)

I would like to work on a one legged stool. Precariously balancing my torso with my feet on the floor, as I think, doodle and type.

I saw some ants waging a war today morning and filmed them on phone Fighting ants! - Shake stabilized



The above video was stablized for 'shake' with a cool l1 optimization algorithm :D

(this is the original shaky video - http://www.youtube.com/watch?v=ZHBT6ubcD2M)

L1 optimization is really close to what my research topic is - motion compensation in xay CT imaging. :D

i donated blood for the first time a few days ago

I donated blood for the first time a few days ago (sat morning, 3 days ago).
I'd given my name in the IISc donors database, A- blood - i'm happy i donated for some emergency reasons.
Along with three other A- donors from IISc - the person needed 4 units of blood urgently.

It was 450ml of it in a bag. I was scared of the needle at first :D But it only hurt while poking, and painless while inside. The blood was oozing out wow nice dark red. Besides I was scared something could happen to me as i am lean and weigh only 61kg while my height is 5 foot 8 inches (or something like that).

Nothing happened! I guess all the cycling gave me good health! I was strong and felt nothing. :) Good - I'm not so weak after all!

Got this link from someone... never tried it myself yet.

Got this news from somewhere.
The following is not my own writing:

-------------------------------------------
Eight-year-old children publish bee study in Royal Society journal

“We also discovered that science is cool and fun because you get to do
stuff that no one has ever done before.”

This is the conclusion of a new paper published in Biology Letters, a
high-powered journal from the UK’s prestigious Royal Society. If its
tone seems unusual, that’s because its authors are children from
Blackawton Primary School in Devon, England. Aged between 8 and 10,
the 25 children have just become the youngest scientists to ever be
published in a Royal Society journal.

Their paper, based on fieldwork carried out in a local churchyard,
describes how bumblebees can learn which flowers to forage from with
more flexibility than anyone had thought. It’s the culmination of a
project called ‘i, scientist’, designed to get students to actually
carry out scientific research themselves. The kids received some
support from Beau Lotto, a neuroscientist at UCL, and David Strudwick,
Blackawton’s head teacher. But the work is all their own.

The class (including Lotto’s son, Misha) came up with their own
questions, devised hypotheses, designed experiments, and analysed
data. They wrote the paper themselves (except for the abstract), and
they drew all the figures with colouring pencils.

It’s a refreshing approach to science education, in that it actually
involves doing science. The practical sessions in modern classrooms
are a poor substitute; they might allow students to get their hands
dirty, but they are a long way from true experiments. Their answers
are already known and they do nothing to simulate the process of
curiosity and discovery that lie at the heart of science. That’s not
the case here. As the children write, “This experiment is important,
because no one in history (including adults) has done this experiment
before.”

Weight machine.... and bicycle weight.

So ... some bicycles are made so light, and every few gram you shave off the weight of the cycle, especially below 13kg or so, it costs so much more.

Is it really worth it?
Depends on whether you're an athlete needing those few seconds of advantage.

It matters on climbs, but not that much. You could carry a 1litre more water (either in you or in a bottle) and you add a kg to the weight. So it really doesn't matter to lighten a cycle in such expensive ways. For people who aren't feeding their families by winning competitions, at least.

Also at higher speeds, aerodynamics matters more. Just google it.

________________________________________________________________________________

I checked my weight today. Before eating, 60.6 kg. After having noodles and a banana (didn't drink any water yet), I checked the weight again. 61.0 kg. Ah! So the weighing machine really works.


This also shows how small shaving off a few hundred grams from an already light bicycle is.

------------------------------------------------------------------------------------------------

But too much cycle weight _can_ be a huge problem especially when climbing. I learnt it going to the top of the nandi with my infamously heavy 9 years old hero ranger swing.

Nandi ride : My first longish bicycle ride

I went cycling to nandi (on my 9 years old heavy ranger swing bought in school (8th std))

A distance of 119.5 km (round trip distance) (on my companion's cyclocomputer)

My previous distance was a 40km (round trip distance) more than a year ago. (Trip to visit my friend.)


People from Bangalore Bikers Club (BBC) (100+ people rode) and IISc Bikers Network (IBN) (6 of us came out of around 50 members)

Photos - a few I took

I am planning to buy a nice cycle now. I am loving cycling.

A very beautiful thing : http://groups.google.co.in/group/bangalore-bikers/browse_thread/thread/47bdc25e7469a11f

Excerpts from the above link:
"Hard exercise makes you brutally honest with yourself, your excuses, your
weaknesses and your shortcomings. There's no room for bullshit when you're
tiring at kilometre 60 and there are still 40 left to go."

"In a car, it's fun to watch the odometer go from 9,999 to 10,000. On a
bicycle, it's like watching a sunrise. "

"People who are killing themselves with chips on the sofa have no business
telling you how dangerous cycling is. "

"Don't listen to haters. People don't like passion about things they don't
have passion for. Find yourself a group of people--in real life or
online--that understands.

It's okay if this group seems like a bunch of fanatics. Passion is
important, and passion for the right things is increasingly rare. We live in
a world full of people who are passionate about cell phones, laptops, cars,
TV shows and IPL. For God's sake give me someone who can talk about pedals
and headsets all day. "

"On a 100km ride, the halfway mark is about 80km. "
