"Should it become clear that the men who rampaged through Mumbai trained in Pakistan, even if the Pakistani government had no hand in the operation, what will stop the Indians from adopting the same position?" link.

that's exactly, my thoughts too.

interesting reading. link.

one of the responses to the above linked post, between == markers.

Every week Mr. Farrell writes an excellent article and it seems like the most sarcastic and naïve people are the first to respond. Rather than ridicule the messenger, you might want to educate yourself and you won’t be so arrogantly optimistic.

A lot of the things Mr. Farrell writes about is indeed predictable. You might want to watch the “Crash Course” by Chris Martenson. He references a transcript to a lecture by a Dr. Bartlett titled, “The Most Important Video You’ll Ever See.” Dr. Bartlett asserts that “The greatest shortcoming of the human race is our inability to understand the Exponential Function.”

Chris Martinson’s Crash Course can be found at this site.

Dr. Bartlett’s lecture is on YouTube. (Part 1 of 8)

If you want a really good read, get "Conquer the Crash" by Robert Prechter. Written in 2002, you would have thought he just wrote it last week. You can get a used copy on Amazon for about half.

it is accepted that electromagnetic (EM) waves can travel through vacuum (absence of media), right? if they are indeed waves in literal sense, then shouldn't they need a medium for transmission?

so, then the riddle is how do they travel in vacuum? if u have insight that'll help me understand the propagation of EM waves in vacuum, PLEASE email me.

i've also posted this Q/riddle and the discussion continues, here.

i'm trying to understand, how an object gets its color. lying the bed last night, i narrowed it down to the frequencies/wavelengths of the contituents of the visible light spectrum and the frequencies of the vibration of the atoms electrons attached to the atoms of different elements of the periodic table. beyond that, my quest is following the following links [pun unintended ;-)].

Physics classroom tutorial. 

Lesson 2(light absorbtion, reflection & transmission)  link [the answer lies in this link!]

Lesson 2(electromagnetic & visible spectra) link

while still on the topic, colors, try mixing/painting red, blue & green together and see if u get white! i've tried it.

xtra link - i haven't read this one yet.

i was in mysore again this tuesday and wednesday and was able to pick up a few coins belonging to the princely states of Travancore, Nizam of Hyderabad and Gwalior. 

2 coins of denomination "oru kaasu" or "one cash" from the period of Bala Rama II minted in 1928. see image here.

1 coin of denomination "half anna" from the period of Jivaji Rao Shindey 

1 coin of denomination "2 pai" from the period of Nizam of Hyderabad minted in 1945 in the honor of King Safwat of Ottoman empire. ref

i was doing some reading on this guy, the Nizam of Hyderabad and was surprised to read that he was the world richest person till 1967! who would have guessed that the land of India had so much wealth in it. see article here.

some food 4 thought. link.
