The Future is Bionic…

I have always fascinated about the powers of the Bionic man. Bionic man is a very wide term whose pinnacle would be to create an artificial being. Today research in that area is progressing – an example of that is the stem cell. But talking about that would be science-fiction. So lets talk about something more real.

…so what about the present?

Have you seen science fiction movies like Avatar, G.I Joe or Iron Man? They wear a suit that

  • enable them to lift extremely heavy objects
  • run at great speeds, and even fly!
  • among other things – Iron Man also had a power source in the suit that kept him alive but that doesn’t interest us! 😉

Do you think such things could really exist, today? Yes, it happened last year at IIT. I was amazed when I saw people wearing a mechanical exoskeleton and jumping over a entire car in a single leap! During Techfest 2009 a team of performers called “3Run” from UK displayed a stunning Parkour performance! Two of them were wearing exoskeletons (3Run doesn’t mention this on their website) which I believe looks just like the ones produced by PowerSkip, a German company.

Solar Eclipse 2010

Unlike my undergrad college an eclipse here is really a celebrated event!

Junta at the event

Krittika – Astronomy club of IITB actually gave solar filters and had even setup a telescope for us to view the eclipse closely.

Here are some snaps I clicked that day:

It is amazing to realize power of technology that lies within our hands today;
high zoom camera + solar filter = sunspots, observed by a common man!

And yes, there were a few, creatively-bent, willing to behold the power of the sun without any fear …

… and dare its true purpose!

Applications In BioMedical Engineering

A System’s Perspective: Computer Science, Embedded and Control Systems

Control Systems and Theory:

  • Understanding and thus modeling of human physiology and pathology.
  • Leading towards applications like controlled medication like drug delivery.
  • Factors like rate and dosage could be controlled.

Computer Science and Embedded Systems:

Integration of computer science with embedded systems has lead to many applications within medicince and healthcare.

  • Machines like X Rays, CT Scan, MRI help diagnose a disease/condition rapidly.
  • While others like defibrilators, pacemakers, dialators and cathetors help keep a patient under check and improve the response time of a doctor.
  • Hapitics enabled Surgical Simulators are a boon for providing high risk Medical Operations and Training today.
  • Visualization Systems that enable 3D Reconstruction of human body from CT Scan, X-Rays, MRI, etc, powered by computer graphics and imaging technology has greatly enhanced understanding & analysis of medical students and doctors alike.
  • Applications like Telemedicine and Telesurgery rely on backbone of Internet and Communications Infrastructure.
  • I envision integration of mobile and healthcare devices in future thus enabling the common man to keep himself under check while on the move.

Why scientists aren’t so famous today?

Richard Hamming

Richard Hamming

I wanted to share this article “Why No Famous Scientists or Engineers?”:
http://boingboing.net/2009/06/12/why-no-famous-scient.html

I especially liked the answer in comment #4: “I think the problem is the lack of revolutionary and easily understandable science/technology”

It reminded me of the legendary talk by Richard Hamming on “You and Your Research” (Video | Transcript)

To summarize what Krishnan said in his reply to the above article (see comment):

  • The work of today’s scientists is not less important than what it used to be.
  • There is a bias in the author’s note.

I agree with both his points. But I also agree with the author’s central point – Today there are lesser scientists who are famous or their work!

Why is that? Where are we going wrong?

The article raised a beautiful point I wanted to share with you – simplicity.
Writing papers or patents today is an Art. Write on everything around the object and nothing about the object! Specifically hide intricate details to avoid leaking your intellectual property.Obviously this makes it difficult for the reader to comprehend the science being described! I have an impression that “in those days” a general scientist wasn’t so insecure about his idea being leaked or stolen. In defense of my very own scientific community,

It wasn’t so commercial, you know!
~ King Julian, Madagascar

What can we do to avoid it?

Why does science have to be difficult to comprehend? Nature didn’t intend it that way. Lets keep our work as simple as possible. To quote the smart guy:

Theories should be as simple as possible, but not simpler
~ Albert Einstein
