May you have a peaceful and joyous “Aluth Avurudu”  (Sri Lankan New Year)

The Sinhala and Tamil New Year dawns today and is celebrated throughout  Sri Lanka.
http://en.wikipedia.org/wiki/Sinhalese_New_Year

Some of the traditional sweetmeats:
Kavum:  Oil cake, made with rice flour, treacle and coconut milk, fried in oil. http://goo.gl/1cMT0W

Kokis: A crispy and sweet food made from rice flour and coconut milk, believed to have been introduced by the Dutch. The batter is first poured into molds and then deep fried in coconut oil. http://en.wikipedia.org/wiki/Kokis

Aluwa: (White rectangular pieces in the photo) made with treacle, sugar, rice flour and added spices.

Mung Kevum: Made with a mixture of rice flour and Mung flour, with treacle and deep fried in coconut oil.

On The Shoulders of Giants

♀ A sepia print of an Indian woman, a Japanese woman and a woman from Syria, dated 1885. What do they have in common? Extraordinarily, each was the first licensed female medical doctor in their country of origin. They were trained at the Women's Medical College in Pennsylvania, the first of its kind in the country. This was a time before women had the right to vote. If they did attend college at all, it was at the risk of contracting "neuralgia, uterine disease, hysteria, and other derangements of the nervous system” (according to Harvard gynecologist Edward H. Clarke). 

An all-woman medical school was first proposed in 1846, supported by the Quakers and the feminist movement. Dr. Ellwood Harvey, one of the early teaching faculty, daringly smuggled out a slave, Ann Maria Weems, dressed as a male buggy driver, from rightoutsid... more »

The Beauty of Frangipani

Nestled in white clusters in a canopy of green
They greet me every morning with a fragrance so sweet
Known as Frangipani, ‘Araliya’ or Plumeria
Beautiful maidens wear them in their hair
Golden yellow centers blending into white
Nature’s gift, what an inspiring sight!

Chemistry of Coconut

✿ The coconut tree is considered as a great gift of Nature to mankind, especially in the tropical Asian Pacific countries where people have been reaping its benefits throughout the ages.

What is so special about the Coconut tree is that almost all parts of the tree are utilized by humans for their basic needs – food, shelter and medicine.

✿ In Sri Lanka, it is traditionally used in religious ceremonies, in cultural events and festivals. Coconut oil is used as a fuel to light lamps by dipping a wick in the oil. The young leaves or fronds are used as decoration for festivals, and the inflorescence ('flower') is used in cultural ceremonies, at traditional weddings to bring good luck to the couple.

✿ Many health benefits are attributed to the unique composition of the oil obtained from the coconut kernel.

Mathematical Qualifications for women

In 1849 Queen's College London started formal lectures leading to some of the world's first official academic qualifications for women.

ON MATHEMATICS
by the REV. T. G. HALL, M.A.
Professor of Mathematics in King's College, London
Presented Jan. 24, 1849

Had the Lecture which I am about to deliver been introductory to the Course of scientific instruction given in these walls, I might have thought it needful, and due to my hearers, to attempt some elaborate proof than I now find necessary, in order to shew that the study of Mathematics is not uninviting ; and may in fact be rendered attractive to a class of pupils so different from that which now for 25 years I have been occupied in teaching.  But the continued attendance of a considerable number of Ladies has shown that there is nothing wanting... more »

Rosalind Franklin, a brilliant scientist who deserved recognition

Those of you who have heard of Rosalind Franklin probably associate her name with the woman vaguely connected to the work done on DNA by Watson and Crick. She was in fact, a brilliant crystallographer, a dedicated scientist,  who made a significant contribution to the field of molecular biology and to the discovery of the Double Helix - structure of DNA

In 1951, she undertook the study of the structure of the DNA molecule as an expert in the field of X ray diffraction.Though DNA was known as the molecule responsible for heredity there were certain facts that eluded researchers regarding its shape. Subsequently, Rosalind Franklin and her Ph.D.student, Raymond Gosling, discovered that DNA exists in two forms (A and B) and that the phosphate units of the molecule were located on the outside. Rosalind also made some... more »

100 leading UK practising scientists

“Science is like an orchestra. It takes many instruments working together to produce a fine performance. At the moment, almost exclusively, it is the virtuosity of the soloists being addressed and praised. Of course, they are essential to science and should be valued accordingly. However, we must, at the same time, recognise and encourage the many other types of contributory scientific talent and experience.” Chief executive of the Science Council, Diana Garnham

A visit to the Peradeniya Botanical Gardens and Kandy City, Sri Lanka

These are photos from a recent visit to the Peradeniya Botanical Gardens near Kandy, Sri Lanka.

The Botanical Gardens includes more than 4000 species of plants and is renowned for its variety of orchids.  The Botanical Gardens at Peradeniya has a long history dating back to the time of the monarchs, but was formally established in 1843 with plants brought from other parts of Sri Lanka and also from the Kew Gardens. http://en.wikipedia.org/wiki/Royal_Botanical_Gardens,_Peradeniya

The city of Kandy is about 5 km away from the Gardens. It was the last capital of the country until Ceylon became a British Colony in 1815.

The Kandy Lake is said to have been built in 1807 by King Sri Vikrama Rajasinha, the last King of Ceylon,  A decorative wall runs for 2060 feet along the banks of the KandyL... more »

A call for conference boycott by women scientists

Almost a thousand scientists have signed a petition protesting against gender discrimination at a flagship chemistry conference, calling for a boycott of the event. The conference in question is the 15th International Congress of Quantum Chemistry (ICQC) to be held in Beijing in June next year.

One of the three scientists who organized the protest says that the  problem is not confined to theoretical chemistry, and that under representation is rampant in all the fields she works in. She had the same experience at a condensed matter physics symposium last autumn.
"It happens over and over again. I know it happens in many fields, because I work at the interface between physics, chemistry, math and engineering, and speak at conferences in each of those fields" she said.

"Salutation to the Dawn"

This glorious sunrise I saw this morning while walking along the Racecourse grounds was awesome. A wonderful start to a new day, a new beginning.

Here I share the beautiful verses of Indian poet  Kalidasa, titled 'Salutation to the Dawn' which are truly inspiring.

"Look to this day!
For it is life
The very life of life
In its brief course
Lie all the verities and realities
of your existence.

The bliss of growth
The glory of action
The splendour of beauty
For yesterday is but a dream
And tomorrow is only a vision,
But today well lived,
Makes every yesterday a dream of happiness
And every tomorrow a vision of hope.

Look well,therefore,to this day
Such is the Salutation to the Dawn"
Kalidasa

Hot water (sometimes!) freezes faster than cold
Yes, it's completely counterintuitive. It's also true. Science Says So. It's called the Mpemba effect in honor of the Tanzanian teenager who brought it to Science's attention.

One day after buying milk... I started boiling it... Knowing that if I waited for the boiled milk to cool before placing it in the refrigerator I would lose the last available ice-tray, I decided to risk ruin to the refrigerator on that day by putting hot milk into it. The other boy and I went back an hour and a half later and found that my tray of milk had frozen into ice-cream while his was still only a thick liquid, not yet frozen.

Testing the effects of cocaine - a fatal experiment!

Cocaine  is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.The name comes from "coca" and the alkaloid suffix "-ine.

It is a stimulant, an appetite suppressant, and a nonspecific voltage gated sodium channel blocker, which in turn causes it to produce anaesthetic effects at low doses.

It is markedly more dangerous than other CNS stimulants, including the entire amphetamine drug class, and  at high doses due to its effect on sodium channels,  can cause sudden cardiac death".
http://en.wikipedia.org/wiki/Cocaine

Although cocaine was used as a local anesthetic, as far back as 1936  doctors noticed that it had dangerous side effects.

Exactly what the side effects were, and what they were at different levels of dosage, was still a fuzzyare... more »

Fermented drinks from around the world

Many fermented drinks from around the world are made from ingredients other than grapes .

Toddy or ‘palm wine’ is a popular fermented drink in Sri Lanka, made from the sap of the coconut palm inflorescence (flower).
Toddy is also made from the Palmyrah palm (Borassus flabellifer ) and Kitul palm (Caryota urens). The sugary sap of the palm inflorescence is tapped and allowed to ferment naturally. If left for too long the alcohol turns to vinegar (ethanol oxidises to acetic acid.)

Here are some traditional fermented drinks from around the world:
In the beverages listed, the alcohol percentage varies depending on the source and fermentation process.  Dark Tea does not contain any alcohol but others such as Basi and Chinese rice wine go up to 16% !

Cheese chemistry - a molecular waltz

As metal arms twirl across a vat of liquid whose buttery yellow colour hints at its destiny, bacteria, enzymes and proteins are doing their own dance beneath the surface. As a well-washed and sanitized hand reaches in, small particles emerge from the pleasant warmth of this molecular waltz

This article by Andy Extance in 'Chemistry World' explains the awesome craft and chemistry of cheese making, how milk proteins are coagulated by bacteria and enzymes, to produce a wide range of cheeses with different flavours, forms and textures.

Battle of the Sexes - Who Cooks Good?

I came across this article in one of Sri Lanka's popular newspapers.

The writer is looking for answers to questions such as
Why are there more male chefs than female in the culinary industry?
If they can cook some amazing delicacies at home, why can’t they take that talent and do something great with it?
Are they not allowed to enter the field in Sri Lanka or do they feel they will not be given a place with the majority being male in the first place?
Why is it that women who are married to chefs never allowed in the kitchen?

Mixed blessings - It is 100 years since Fritz Haber discovered the "Haber Process" for the synthesis of ammonia

It's 100 years since Fritz Haber invented a method to  synthesize ammonia – helping to feed billions but also to kill millions, and contributing to the pollution of the planet
http://goo.gl/GyQdmc

The Haber process uses nitrogen from the atmosphere as its key ingredient to synthesize ammonia. This process helped farmers across the globe by providing ammonia fertilizer at a time they were running out of natural fertilizer for their crops. A hundred years ago, the Haber plant at Ludwigshafen  run by the chemical giant BASF, produced ammonia in industrial quantities for the first time. "Bread from air," ran the slogan that advertised Haber's work at the time. Undoubtedly, a very important discovery.

Galle Fort re visited after 50 years!

A memorable visit to the Southern seaside city of Galle, Sri Lanka

Galle is a coastal town in southern Sri Lanka (formerly Ceylon). The Galle Fort is popularly known as the ‘Dutch’ Fort, but it was first built by the Portuguese in 1588 and later fortified by the Dutch.

Galle has a colourful history dating back to the 16th century, and the Fort is now recognised as a UNESCO World heritage Site.

For those interested, Wikipedia provides a good description of the Galle Fort.
http://en.wikipedia.org/wiki/Galle_Fort

On a personal note, Galle is where I grew up in a multi ethnic cultural environment, where I started schooling and spent most of the first 12 years of my life. Although I have visited Galle many times in the past, it was last week on Sunday the 13th October, that I was able to spend arel... more »

Photograph of Van Gogh Sunflowers comes to light

A painting of sunflowers known as the Vase with Five Sunflowers, by Vincent van Gogh was destroyed in a fire after the bombing of Osaka during World War II. A rare photograph of this painting  has been found in the archives of a Japanese museum. It shows  how the artist wanted his work to be seen. It was sold to a Japanese collector and shipped to Japan in 1920. But it was destroyed in a fire after US bombing of Osaka during World War II.

The painting shows the flowers against a dark blue background framed in orange.

It's a pity that the original was destroyed. I have always been fascinated by the Sunflower paintings by van Gogh and have shared posts about them from time to time:

Chemical Weapons - the deadly nerve gas Sarin

A recent news item reports of an attack on civilians in Syria, probably by the deadly nerve agent Sarin
http://goo.gl/IBMo1o

The news is very disturbing and has shocked the world. The use of such weapons of mass destruction is a horrendous crime against humanity. This is not the first time that chemical weapons have been used against civilians. The attack on the Tokyo Metro in 1995 and later in Iran remind us how science has been used for evil purposes by mankind.  So many innocent victims including children have suffered terrible deaths from these attacks. The effects of nerve gases such as sarin and other organophosphates are profound. The victims eventually die of suffocation due to respiratory failure. Victims who survive the attack can be left paralyzed or permanently disabled due to lingering neurological problems.more »

Importance of Food texture

✿If we have the unfortunate experience of tasting mushy apples, rock hard bread or gritty ice cream,  we begin to  wonder what has gone wrong with our food. We are annoyed and irritated when the  texture is not right and the food is quite often rejected. So how important is food texture?

✿We can roughly divide foods in to two groups based on texture. The first group consists of foods containing the basic structure of living tissue such as meat, fruits, potatoes, nuts etc.,  and the second group contains those that have undergone some processing such as bread, butter and ice cream.

✿In the first group, the texture is very much determined by the structure of the tissues and the cell components. In foods of animal origin, the  proteins determine the texture to a large extent, while in the case of fruitsand vegeta... more »

All about books

I really liked this quote by Gilbert Highet outside the building of the Barnes & Noble Book Store near the Inner Harbour area of Baltimore.
Gilbert Highet(1906-1978), was a Scottish-American writer and an academic. He published essays and books, hosted his own radio programme and was involved in many activites to publicise books and encourage the habit of reading.

What Highet said about books: "These are not books, lumps of lifeless paper, but minds alive on the shelves. From each of them goes out its own voice... and just as the touch of a button on our set will fill the room with music, so by taking down one of these volumes and opening it, one can call into range the voice of a man far distant in time and space, and hear him speaking to us, mind to mind, heart to heart" http://goo.gl/3laQ2

Historic ships at the Maritime Museum in Baltimore.

During  my recent visit to +Rajini Rao   at Baltimore, I spent some time looking around  the Inner Harbour area. Some of the historic ships such as the United States lightship Chesapeake, USS Constellation, and the USS Torsk (SS-423) were docked there in the maritime museum located in the Inner Harbour.
The USS Torsk (SS-423) is one of two Tench Class submarines still located inside the United States. It is nicknamed the "Galloping Ghost of the Japanese Coast."
USS Constellation is one of the last sail-powered warships built by the US Navy.
