Who contributes more DNA mutations - a male or a female?

Mutations are considered bad.
  • only about 24 mitotic divisions occur from the fertilized egg that starts a little girl's embryonic development and the setting aside of her future eggs (which is done long before she is even born). No matter what the age of the mother, she transmits only about 15 new mutations to her offspring.
  • The sperm of a man, in contrast, are the descendants of at least 400 mitotic divisions since the fertilized egg that formed him. A man continues to add one to two new mutations every year. 
So,

A 25 year old man contributes ~25 times more mutations than the mother (mother's age does not matter) to the baby.

A 40 year old man contributes ~30 times more mutations than the mother (mother's age does not matter) to the baby.

Biography of Sri Hiriannaiah

I read the following biography of Sri Hiriannaiah at http://rajchat.info/vasudeva_kutumbukam/7_two_exemplary_officerst.html. Sri Hiriannaiah also belonged to Bobburkamme sect and most probably our family is related to his family, exactly how I don't know but may learn in the future. What was interesting is the propensity of descendants of Sri Kalappa to pursue law and serve in justice profession. The entire biography is copied from the above source. " Sakleshpur Hirianniah (S. Hirianniah for short) was born on 24th of June 1877 in Sakleshpura which is a taluq headquarters town in Hassan district. The taluq is situated in the high mountainous area of the Western Ghats, The mountains are covered by tropical forests where grow teakwood, rosewood, sandalwood and other tropical trees, and there is very heavy rain during the monsoon months. The ground under the trees are covered by all sorts of plants and creepers an...

My MOOC Progress

I finished my first MOOC course "Introduction to Mathematical Thinking" taught by Keith Devlin of Stanford, an outstanding professor. It was a tough course! I am almost half done with "Introduction to Genetics and Evolution" taught Mohammed Noor, another outstanding professor from Duke. I have already learned a great deal from this course. This is a tough course too. Believe it or not, I have signed up another 16 MOOCs! Within a month, three courses will be starting; Think Again: How to Reason and Argue , Introduction to Astronomy , Drugs and the Brain .  The New York Times called 2012, the year of the MOOCs, see http://www.nytimes.com/2012/11/04/education/edlife/massive-open-online-courses-are-multiplying-at-a-rapid-pace.html?pagewanted=all&_r=1&.

401K, 403B Rollover into an IRA

I am trying to gather info on the IRA rollover. I am piecing together info I found on the web. 1. Can I Use an IRA Rollover to Move Funds Out of My Company Retirement Plan While I Still Work There? Probably not. Most company retirement plans do not allow you to roll funds out of the plan while you are still employed. To find out if they do, you can call your plan sponsor, and ask if they allow what is called an "in-service distribution". Does AT&T allow? Does TIAA/CREF allow? An in-service distribution is a different type of transaction than a loan or hardship withdrawal. An in-service distribution is a transaction where you can rollover a portion of funds in your plan into a self-directed IRA account while you are still employed. Only some plans allow this. No Longer Employed Once you are no longer employed, it may make sense to roll funds from your plan into an IRA account. At that time, to avoid tax withholding, you'll want to choo...
