Infinity Column - The Impossible Puzzle
The following seemingly impossible puzzle had haunted the brains of many puzzle solvers. But a quick little insight or that Aha! moment as Martin Gardner told us can give a key to solve the puzzle in minutes. Solve and Claim the "High IQ Genius" title from KAZ.
A car traveled from the City of Cheshire Cat to the City of Mad Hatter in the Wonderland of Alice and It took Three whole Hours for the journey. On the journey back to the City of Cheshire Cat to her great amusement Alice found it took Three and Half an Hour to reach the destination. The way was full of plains and hilly terrains. The data Alice was given is:
The speed Alice's car on uphills is 50 mph(miles per hour),downhills is 75 mph and on plains the speed is 60 mph. Help the Alice to find the distance between these two cities in Wonderland.

When I was a small boy I read this book in Tamil and immensely enthused by it in the field of electronics. I can never forget those days of adventures in happy reading.

Celebrating the Mission Moon - A Golden Jubilee of Mankind's Apollo Moon Landing
Fifty years before this day, On July 20,1969 at 20:17 UTC, Neil Armstrong and Buzz Aldrin landed on the Moon, which had been only an object of mystery since the dawn of the mankind. They who landed on Moon really made big stride for the mankind they represented.
Here, you can see Buzz Aldrin posing on Moon. The man who shot this photo was Neil Armstrong and You can see him and a part of the Lunar module reflected in the visor Aldrin was wearing.

The Grand Event of the Year - Chandra Grahan of Guru Purnima - July 17,2019
The Eclipse Began @ 1:20AM, July 17,2019
And the shadow of the Earth had done with the Moon at 4:40 AM. It was a nice show apart from the intrusion of (more than often) cirrocumulus stratiformis clouds. The poor quality of my mobile cam had been a bigger nuisance and I'm really longing for a high end DSLR camera which would cost around Rs.35,000/- at least. The direct view through the Telescope is much better I promise you. Last but not the least, I was able to capture with long exposure shots(32 sec) the surrounding my nocturnal abode and they were eye catching.

NASA Astronomy Picture of the Day - What is this in front of the Sun?
Just see the NASA's Astronomy Picture Of the Day on July 15 absolutely gorgeous and spotless sun in HD. But without googling it could you guess what is that spot that seems to be hanging there in the top upper left limb of the sun's image?
If you guessed it right could you calculate its' distance from the Earth with the aid of a bit of googling.
A new challenge ! Work it out...

Fresnel Diffraction of Green Laser Light by Floating Dust Specks on Polymer Gel Balls
These Fresnel diffraction patterns of minuscule dust particles can be easily observed by passing green laser through polymer gel balls and projecting the image on a screen,wall or ceiling. The dust specks floating on the surface of the polymer balls got very much enlarged in their image by the lens action of the transparent polymer balls beyond the diffraction limit. As a result one can see beautiful alternating bright and dark rings around the image of dust specks which overlap with each other to produce a mesmerizing effect.
A humble demonstration set up I used at home is shown below:
A few of the diffraction images obtained with the method are show below:
