Today I came across an interesting online article on Smart Glasses invented by Prof. Yasuo Kuniyoshi from Japan. Supposedly it can help you find anything that you are looking for. So much for those misplaced car keys!! :-) Check this out.

Ringtone for an Alarm? yeh right!? May 1, 2008

Filed under: Uncategorized — tnallamshetty @ 9:47 am

I don’t know about you guys, but the only alarm I have is my cell phone. Guess what happens every morning when the alarm goes off? The ringtone is so interesting that I either start to enjoy the music in my half-asleep state or start dreaming. I guess its time for me to go buy a good old buzzer that annoys the heck out of you. U know? :-)

 

Present is Past? April 12, 2007

Filed under: Science — tnallamshetty @ 2:22 pm

It’s easy to jump to conclusion that past is gone, future is not here but only present is all there is now. But if we think about it, the present is so small that whatever we perceive and do is actually past. I will give you an analogy in the second paragraph. Hearing the word “Past”, we think that we are dealing with something an hour ago or yesterday or last year or 1000 years ago. But even a nanosecond earlier is past too.

 

Here is an analogy.

Say…you are looking at yourself in the mirror. You might think that you are looking at yourself in present. But light travels with certain speed…doesn’t it? 299,792,458 m/s to be precise. That is roughly one foot per a billionth of a second. That means your image (light) has to get reflected from the mirror to the retina of your eye, which then gets processed in the brain. Only then you can see your reflected image. That means…what you are looking at is actually a delayed image that happened a small fraction of a second ago. We don’t feel the time lapse because the time delay is extremely small.

It’s not possible to change the actual present because it exists in a fraction of a fraction of a fraction of time and by the time you think about it, it’s already past. George Carlin once said “There is no present but recent past and immediate future”. I totally agree with that concept.

That is not to mean that present is not there. It is there (or should I say was there). By the time we perceive it, its already past. It would be erroneous to cough and say that I just coughed in the present time because I coughed a second ago, which is Past, not Present.

 

 

Are we Alone in the Universe? April 8, 2007

Filed under: Science — tnallamshetty @ 2:06 pm

Are we alone in the universe? I would say “No”. We can’t possibly be alone in this universe.  For some it may sound cliché and for others it may not.

Now…is it that little green man that Hollywood and media projects that I believe in?…May be or may be not. I am not sure about that. I think alien life doesn’t necessarily have to be this intelligent little green creatures. No doubt I love watching them on movies and TVs. UFO controversies really raise eye brows. No doubt about that. But, for me, even if we find microorganisms or a unicellular life elsewhere in the universe, that’s a big thing. Little green man or other Hollywood alien characters might just be a product of creative cartoonist and we can’t be sure how exactly extraterrestrial life would look like until we come across one for “real”. But I DO believe in life forms elsewhere in the universe, although I dont know how they look like.

 

Instead of beating the same old trumpet let me say few things. The best evidence that universe supports life is none other than “we, the earthlings”. We sometimes talk about space as though it’s an outside entity. But we are not separate from space. We are in space. We live in space. We live on this tiny planet floating in space, revolving around medium sized Star called “Sun”. If we are the live example of life in the universe, there got to be life elsewhere too since the universe is simply too big.

 

Our universe is filled with billions of galaxies and each galaxy in turn has billions of star systems, which in turn has planetary systems. If our earth could exist in one of the star systems (our solar system), we have astronomical number of planets that we know exist but don’t have a clue about. We know for sure that one planet (our earth) among those trillions of possible planets has life. We are the sole example to say that life is not impossible to occur in universe. There is 100% chance that there are planetary systems out there with right amount of ingredients to sustain life. We are yet to uncover our own solar system let alone other galaxies some of which are billion of light years away. How can we say life doesn’t exist in such a multitude of star systems spread across the universe. It would be arrogant on our part to think that we are alone in this universe, when it is filled with billions of similar galaxies and identical star systems. Biology could exist elsewhere too.

 

Saying that the entire cosmos can’t hold any kind of life is contradicting our own existence. When we believe in math so strongly, which has several theorems that are proved by contradiction, why not use the same principle to life elsewhere.

This is just a thought. Suggestions/comments/corrections/other perceptions are welcome.

 

 

Chicken or Egg? Which came first? March 2, 2007

Filed under: Uncategorized — tnallamshetty @ 10:00 am

This is an age old and classic question which puzzles everyone even today. I read a recent article about this on a major news website. It had a long list of debate questions and interesting answers and finally concluded that Egg came first. The reason being….even though logically we might think chicken must lay egg for egg to come into existence, the scientific debate concluded that since life starts in basic embedded form and since egg is more basic than its evolved complicated version called chicken, egg must have come first. An egg has everything embedded with basic ingredients but which has a all the complicated DNA stored in it already. So scientists think, it’s easy for egg to show up with ingredients from nature instead of chicken showing up magically without an egg.

 

Even though this answer caught my attention, I still want to keep an open mind and search for more intelligent answers since it keeps your mind healthy by thinking about all the rational possibilities. I also want to share another thought. This might sound crazy but…I think single celled organisms might have evolved without egg just by using the right amount of ingredients like carbon, sunlight, water and minerals. The evolved organisms might have gone through several mutations and eventually might have grown into multi-cellular organisms over the period of time. After the evolution of complex organisms, may be those organisms started laying eggs to replicate itself or multiple itself. This will leave the conclusion that chicken came from an ancestral single celled organism and not from another chicken or egg. Well…whatever the true answer might be, these are all big questions that still interest us.

 

Besides, I read an article on NASA several years ago about how sexual reproduction might have taken place after significant period of evolutionary time. Till then, organisms would multiple themselves like Hydra or Potatoes. Interesting theory.

 

Of course….theologically speaking, we can say…god created chicken and close this question. But that will not leave room for rational constructive debate. I am a believer in higher entity that we may call God or energy or supreme soul or whatever we want. But that doesn’t mean we have to ignore theory of evolution. We all have brains not to keep it idle but to utilize it to think about a subject, ponder upon it, debate and try to understand it rationally and still keep an open mind. May be I am right. May be I am not. Or may be I am wrong in my whole analysis and assumptions. Doesn’t matter whether its right or wrong, but just the fact that we are discussing about this topic in itself makes it worthwhile to think about it. J
