Early bird gets the free sex?

From: Nature - June 11, 2015

Lazy male birds pay a high price





Male songbirds that sleep late risk having their female partners mate with another male.
Mating outside of a monogamous pair in birds normally happens early in the morning. To find out if rising earlier or later would affect reproductive patterns of great tits (Parus major), Timothy Greives of North Dakota State University in Fargo and his co-workers captured male birds in Germany and implanted them with a device that releases melatonin. This hormone is generated mostly at night to set the circadian clock. Male tits that had night-time-like levels of melatonin around the clock began their daily activities on average 10 minutes later than the control group. Their nests also contained more offspring fathered by another male, suggesting that the late-rising males were less able to defend their mates.

A Well-ordered Thing: Dmitrii Mendeleev And The Shadow Of The Periodic Table - Book Review

The man and the country behind the periodic table!


The periodic table would match any other basic scientific discovery on the impact to science and most of us would have heard of Mendeleev (though we might spell it and pronounce it in many different ways). However compared to many other well known scientists like Newton or Darwin or Einstein, we would be hard pressed to recollect much additional information about Mendeleev. We would also be surprised to hear that he came out of Russia - country hardly known for its scientific prowess in the 19th century. Michael Gordin aims to set that right and shows us a full picture of Mendeleev across his life time and the life and culture of Tsarist Russia at that time period.

The author makes it clear that this is not a traditional biography. His plan is to highlight the dilemmas of a nation at the cross roads of history and the achievements of a polymath from a poor background who nevertheless achieves tremendous success (along with failures). And that makes a fantastic story. How come the Periodic table came from Russia? What were the steps that led Mendeleev on this path? How did the final table evolve? What were the other areas that Mendeleev worked on? What were the challenges that he faced? These are the questions that you will find answers to, in this book. Some of it will seem very relevant to modern times - the play of economics, politics, superstition in science and society seems to apply equally well in the 21st century.

This is a good read for anyone interested in history, culture and science. The story of a gifted individual and a great nation and the impact of fundamental transforrmatory forces on them will be difficult to forget.

A Primate's Memoir: A Neuroscientist's Unconventional life among the Baboons by Robert Sapolsky - A Book Review


Exploits of a ‘hippie scientist’ in Africa


This book is supposed to be a study of the baboons in Africa by a neuroscientist. The author ‘joins’ a troop of baboons  in Kenya, gives them various names from the old testament and monitors them closely. Joining is obviously an exaggeration as the author is armed with his jeep and other accessories but more or less camps closely to the troop and tracks the activities of the troop members. The main objective of the study seems to be tracking the stress level of the male members as they pass through the various hierarchical positions in the troop. This is achieved by anesthetizing them occasionally using a blow dart gun and then taking their blood samples. He also observes the social behavior of the members including tracking ‘who is making out with who’.

Only less than 20% of the book cover the baboons while the rest is spent on various adventures of the author in different African countries, in the national parks as well as interactions with the ‘black’ natives. A typical western person’s view of African life is depicted in those descriptions if one can suffer to read through all of it. How much of these are ‘hallucinations’ and what are real is difficult to make out.

I don’t think this book merits as a science book by any standards – since very little of science (forget neuroscience) is covered. Couple of chapters (one in the beginning and one towards the end) are interesting from a view of understanding baboon group behavior. However the author hardly seems to take into account the trauma he must have been imparting on the group by walking around and darting them! He acknowledges that they would run away from him and it was an uphill task for him to get close to them, as time went along. It is a basic rule in science that the process of measuring does affect the metric that you are trying to measure – but in this case the stress level induced by the scientist would dramatically influence whatever he was trying to measure.

Maybe my criticism is unduly harsh considering that the study was done many years back and the book itself was published in 2001. Reading it in 2015, I would be looking at it from a much later perspective. But  still, it will be hard to deny the basic facts that I have highlighted and I would not recommend anyone wasting time with this book.

Tongwan City by Gao Jianqun - a book review



The Hun King and the Buddhist Monk in ancient China

The mention of a Hun King would bring the name of Attila to most people’s minds. However in Tongwan City, Gao Jianqun tells us the story of another Hun King ‘Helian Bobo’  in the same time period as Attila, who established a large empire and created a magnificent new capital city in record time in present day Mongolia. While Attila was challenging the Western civilization, Helian Bobo was rocking the foundations of the Eastern one. From a penniless orphan, Helian became an emperor in a couple of decades. And within 6 years of time and the labor of over 100,000 people, his capital - the Tongwan city was brought to life in 419 AD. Thousands of people died during its construction and they were buried in its walls.

During this time period, China and Mongolia was heavily influenced by Buddhism from India. So enamored had the Chinese Kings become with Buddhism that they sent an army to India to bring by force one of the most well known Buddhist monks of that time – Kumarajiva. It is said that over 30,000 of his followers also accompanied him to China.. Kumarajiva spent the rest of his life in China translating all the Buddhist teachings to Chinese. Though Helian Bobo and Kumarajiva do not cross paths much (except for a brief meeting once) their stories are intertwined in this tumultuous period of China and Mongolia.

The Hun lifestyle was a migratory one with the horse as their main support. Their culture and philosophies are brought to life in this book. There are not too many historical fiction books on the ancient Chinese period and hence readers will find this book provides a window to that past. The writing style is brief and crisp and different from the normal English prose that we are familiar with. However as you get into the novel, it becomes more familiar and you will enjoy the gripping story and unforgettable characters.

"Rookie Smarts" by Liz Wiseman - Book Review


How to develop a 'perpetual rookie' mindset


I have never been very fond of rookies – upstart behavior and ignorance puts me off. But the tag line ‘Why Learning Beats Knowing’ attracted me to the book. Being in the knowledge industry that is something that resonated with me.

Reading the book was a good decision – Liz Wiseman shows how an unencumbered mind can gather expertise quickly, and with no baggage to weigh them down how a rookie can perform well in the new world of uncertainty. Further she shows how all of us can keep a rookie mindset even as we grow older.

However a couple of areas are not addressed adequately – (a) you have to be pretty smart in the first place (b) the stories are based on the western culture where an open educational system encourages questioning; I am not sure if rookies will fare so well in the eastern world – where ‘experience’ and ‘rote learning’ are given more weightage than independent thinking.

In many situations experience can be a liability. And most often the experienced person does not see the baggage he or she is carrying. “Rookie Smarts” gives many examples of how one can overcome this and develop a perpetual rookie mindset
