Museum of Natural History New York

Long time ago i had an opportunity to visit the Museum of Natural Histoy in New York, and i was suprised by the number of visitors. People from all over the world congregated at the entrance as well as school children of all ages from kindergarten to university.

The access to the museum is was the main reason why people flocked there, it is easy you get there and you choose how much you want to pay for you to enter the museum. they have suggested fee but you can pay whatever. For me suggested fee was 12 dollars but you can pay even one dollar and get entrance ticket..

We have museums too in africa and surely will represent the history better than the foreign museum but where is the publicity to attract people and why is it expensive to get access to the museums in africa...

It is a shame that one has to travel accross the world to learn their own history because we have sold all artefacts to foreign museums..

Science in Africa?

Science is the backbone of human development..all developed countries rely on their universities to maintain,develop, invent new technologies that make life easier and better and bring about huge economic growth. I don't know the purpose of universities in most of African countries!! it is frustrating and dissapointing!! When will we wake up and face the reality?

Gain Measurements using Multi-section device

Finally i have been able to measure Absorption of light using two sections of LASER device, by pumping sections independently and measure light intensity spectrum using OSA. Also by varying the pumping stripe length i am able to determine the gain of the device. It has been a rollercoaster weekend trying to make sense of all these measurements and apply Beer-Lambert Law to see the absorption spectrum..(aligning optical fiber to 350 micron facet is not trivial...)

Sound does not travel through Vacuum for a Reason

Imagine if sound was able to travel through vacuum..the sound of the SUN explosions would have been catastrophy to the neighbouring planets including the Earth. So was the BIG BANG a quite event? I wonder!!!
