The Emotion Machine

I could not resist posting this here. Marvin Minsky a professor at MIT and a legend in his own rights has published after over 20 years. In his new book called "The Emotion Machine", he argues that emotions are a different way of thinking and hence are not different from rational thought.

This doesn't surprise me, it gives words to what I have been struggling to give a form. Many a times I felt emotions have a place, not every thing is based on logic as we think, but could never find an explanation for this feeling. Marvin's idea leads me on to a whole different gamut of thoughts.

Coming back to the news about the book, you can read his interview of his at "boston.com". I present a few excerpts from that over here.

"Q So here you are, a pioneer of artificial intelligence, writing a book about emotions. What's going on?

A Somehow, most theories of how the mind works have gotten confused by trying to divide the mind in a simple way.

My view is that the reason we're so good at things is not that we have the best way but because we have so many ways, so when any one of them fails, you can switch to another way of thinking. So instead of thinking of the mind as basically a rational process which is distorted by emotion, or colored and made more exciting by emotion -- that's the conventional view -- emotions themselves are different ways to think. Being angry is a very useful way to solve problems, for instance, by intimidating an opponent or getting rid of people who bother you.

The theme of the book is really resourcefulness and why are people so much better at controlling the world than animals are? The argument is: because they have far more different ways to think than any competitor."

"Q What, then, is the most important thing for us to understand about our own thinking?

A Your mind can work on several levels at once so, when you think about any particular subject, you also can think about the way you've been thinking -- and then use that experience to change yourself. Similarly, when you admire some teacher or leader, you can try to imitate their ways to think -- instead of just learning the things that they say."

It's a paradigm shift for all of us. Grab it and address beautiful problems for humankind.

Pharmacogenomics: Biochip

The world's first pharmacogenetic microarray for personalized prescriptions

The new technology combines chemistry, physics and biology to develop electronic devices able to reach diagnostic conclusions. Roche has combined its polymerase chain reaction (PCR) technology for putting genetic information on a chip.

When two people take the same dose of a drug, their bodies may metabolize it so differently that the amount of it that can act on its target varies tremendously. Some people may have an especially efficient form of an enzyme that breaks down a drug; others may have a less functional version. People with genetic variations that give them less efficient versions of the enzymes, known as poor metabolizers, could have high levels of a drug in their body for a longer period, increasing the potential for side effects.

The AmpliChip CYP450 Test provides comprehensive coverage of gene variations - including deletions and duplications - for the CYP2D6 and CYP2C19 genes, which play a major role in the metabolism of an estimated 25% of all prescription drugs. It is intended to be an aid for physicians in individualizing treatment selection and dosing for drugs metabolized through these genes.
