Nikon D5300


Finally got my Camera and ended up with Nikon D5300. Looks like it’s a great beginner dSLR. The new gallery is hosted here: Attended a class to learn about cameras at Digital Photography Academy.

wK1Gsjc+S47lAAAAABJRU5ErkJggg==1/22/15: Upgraded with AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR lens which is awesome. I can see a huge different with my shallow depth of field. I have to switch between 18-55 & 55-300 time to time. But I got the best of both worlds now…

2014 Biking Season

Started my 2014 bike ride with my 2012 Trek Madone 3.1 Apex. It’s a great bike and it has a carbon fibre frame.



North Shore Cyclists

  • Apr 13: Topsfield Plaza start – Rainy day and happened to start with short 20miles. Forgot my full gloves which gave me lot of paid at the end of the race after soaked in rain whole ride! But I felt better
  • Apr 20: Scotty Dog Ride – It was cold for me. But I managed to do the short ride of 23 miles in 2 hours or little less. Damn, I started little late than everyone else. The arrows were pretty clear and not much of uphill. I saw Jim finishing up his Medium ride. Good to be back with 25 miles. Let me see if I can go for Medium rides if the weather is good next week.
  • May 4: Merrimack River Ride – It was a great weather, little windy, beautiful bike map, lot more folks showed up today. I picked up the medium ride today and ended up doing fine. I was beaten up on one of those hills but the rest of them I did really good. Forgot my water bottle but didn’t need much. Took about 2:15 hours and mostly stayed with the group. It was so easy when you stay with the group than riding by yourself.
  • May 11: Manchester Ride: It was a great weather and I picked up 25 miles ride with a small group. I was the tail for the group and we enjoyed the view. Ellison and Steve are the ones I followed all the way to the end. I liked the restaurants at the way. Hope to go back at some point. I think we took about 25 miles and as usual I forgot my water or drink.
  • May 27: Memorial Day Ride in Newbury Port – Great weather and finally I made it on time there but stared a little late. I was able to catch up with the pelaton slowly. The same hill again! I stopped at the middle and took a minute break and I sprinted all the way to the top. Good feeling! I listened to the music and didn’t get lost at all. Also, did some extra mile with a drive on a bridge which was beautiful.
  • Jun 8: My favorite ride in Plum Island. I forgot my wallet where I had to pay $2 for entrance fee for the island. The guard let me sneak in and finally I get to complete it. I am happy that I was on time to get started with the group and slowly advanced and finished almost 3rd in the 32 miles group. No break, no water and it was a long stretch.
  • Jun 29: Going back into 133 is always fun. I went 5 minutes late ! as usual and forgot to wear helmet in my first mile. Ended up coming back and got the helmet and finished the ride in 1:40 for about 26 miles. It was a good ride and didn’t see many on my way but music helped a lot to get me back to the starting point.


Collatz Conjecture

Mitran & myself watched this movie “Contact” recently and we got inspired on SETI project. When we got into sharing our computers to run those applications to find something new to fields, we decided to pick one from Mathematics.

What is Collatz Conjecture ?

Take any natural number n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process (which has been called “Half Or Triple Plus One”, or HOTPO) indefinitely. The conjecture is that no matter what number you start with, you shall always eventually reach 1. The property has also been called oneness. (wikipedia)

This is good enough for me to get started on proving that there is a number which has this infinite loop not ending with 1! I did that for couple of days and my results are like this:

Mitran’s understanding of this math:


I joined BOINC project couple of weeks ago and starting running this project. Then I tried to find out where it stands after so many days. It’s a private project and I don’t think it’s just there because it’s just there. There is no specific goals or any mathematics value for this. There is no real world application which is waiting to be used. There I decided to stop my crazy computers crunching numbers to find the first number for the conjecture.

How to live longer?

Damn, people always believe in this shit. I was reading this book about Einstein’s “Theory of Relativity”. They were talking primarily the concept of non-absolute things. Absolute space was not true. Because, everything in the world is moving. Earth is circling around Sun as well as spins itself. The entire solar system is part of Milky Way. You know that it’s faster than something we wanted to know. That means, if you are getting a piece of land from a real estate broker, he cheated you with illusion that it’s the place you own. I don’t think it’s true to find the exact location in this world because there is no still point of reference.

The second thing is about time. For example, if you are looking at a moving train which has a light clock. Hold on a sec. I don’t think i will make this easy with the book example. But the idea is that if you travel fast enough (close to the speed of light – 299,782,458 meters/sec), the person who is not traveling will age faster than you. Otherwise, your clock will be slower than his clock. His 1 day will be different from your 1 day.

The only thing which goes close to 99.94% of light speed is muons in CERN labs. When the particle travelled 99.94% of the speed of light, it’s life was 28 times longer than the particle which was at stationary. The picture i tried to draw and understand the book example may help if you are interested.
