  秦王谓唐雎曰:“寡人以五百里之地易安陵,安陵君不听寡人,何也?且秦灭韩亡魏,而君以五十里之地存者,以君为长者,故不错意也今吾以十倍之地,请广于君,而君逆寡人者,轻寡人与?”唐雎对曰:“否,非若是也安陵君受地于先王而守之,虽千里不敢易也,岂直五百里哉?”

     A winner of the 2011 L'Oreal-UNESCO For Women in Science Awards, Professor Vivian

Wing-wah Yam says she could not have done it without the backing of her family.

     The road to scientific discovery is tougher for women than for men and Professor Vivian Wing-wah

Yam says she couldn't have succeeded without such a supportive family. The 47-year-old from Hong

Kong University was one of five women scientists, from each continent, to receive the 2011

L'Oreal-UNESCO For Women in Science Awards at a ceremony on March 3, at UNESCO

Headquarters in Paris. It is the 13th edition of the award since 1998.

     Yam's long and fruitful research on solving the energy problem won her the prize for Asia and the

Pacific. There are several renewable and sustainable(可持续的) energy solutions, like solar power,

which could provide an unlimited source of energy. Some problems must be resolved, however, such as

the low efficiency of solar cells and their high supply costs. Yam and her colleagues hope to overcome

these problems by developing and testing new photoactive(光敏的) materials.

     She became the third Chinese women scientist honored with the so-called "woman's Nobel Prize"

award, after Professor Li Fanghua from the Chinese Academy of Sciences in 2003, and Professor Ye

Ruyu from Hong Kong University of Science and Technology in 2004.

     "People think chemists are bad guys, but we are the good guys," Yam said in a humorous aside

before explaining her research project on photoactive materials in an earlier speech at L'Institut de

France. For Yam, chemistry is science, but also an art. Amazed by the universe, nature and color in her

childhood, Yam decided on a career in chemistry. "One of the beauties of chemistry is the ability to

create new molecules and chemical species. I have always associated chemists with artists, creating new

things with innovative(革新的) ideas," Yam said.

     As a mother of two daughters, 12 and 14, Yam said she is lucky to have been supported by her

family. She was inspired as a child by her father, a professor in the Civil Engineering Faculty at Hong

Kong University. Yam added her husband, Mak Shingtat, a PhD in chemistry, who accompanied Yam

to the awards ceremony, was also fully supportive of her work. "I can't imagine how my career could

move on without his understanding and support," she said. "I often stay late at night in the laboratory. He

always waits for me outside."

     Yam received her bachelor and PhD degrees from the University of Hong Kong (HKU). She taught

at City Polytechnic of Hong Kong before joining HKU as a faculty member, and headed the chemistry

department for two terms from 2000 to 2005. At 38, she was the youngest member elected to the

Chinese Academy of Sciences. She is also a Fellow of TWAS, the Academy of Sciences for the

Developing World, and was awarded the State Natural Science Award and the Royal Society of

Chemistry (RSC) Centenary Medal. 2011 is the 100th anniversary of Marie Curie's second Nobel Prize,

coinciding (一致的)with the International Year of Chemistry. Today, Curie is still a role model for women

in science.

     Although the participation of women in science, is promoted by UNESCO, notably through

L'Oreal-UNESCO, there are still too few women doing high-level science, says UNESCO

Director-General Irina Bokova. The latest UNESCO report shows less than 40 percent of countries

provide girls and boys equal access to education.

     Each year, the L'Oreal-UNESCO For Women in Science Award recognizes 15 young women

from all over the world, especially developing countries, to encourage and finance their studies. More

than 200 young women scientists are currently supported. "I do not think there is a difference between

men and women in terms of their intellectual abilities and research capabilities (能力)," Yam said. "As

long as one has the passion, dedication and determination to pursue research wholeheartedly, one can

excel regardless of one's gender or background."

    Yam said some young women, who require stability and security, often have to give up their research

because of family pressures. "The only way for women to succeed in science is to get the mental and

material support from family and society. There is a day-care center at my university, and my husband

and mother-in-law help a lot with the housework, so I am able to spend my time on research," she said.

"I have two young daughters, and it is too early to tell whether or not they want to pursue careers in

science. But, I will encourage them to always defend their ideas. To remain determined, and to never be

afraid of failure - this is the advice that they will need to succeed in realizing their dreams."

     Yam also acknowledged her colleague's support, at the awards ceremony. "This (award) not only

recognizes me, but my colleagues and students and my country, China."
