Barbara McClintock: Against The Genetic Grain

The tale of much of Barbara McClintock’s life is that of the scientist working long hours with a microscope seeking to solve mysteries. The mystery she spent most of her career trying to solve was how all cells in an organism can contain the same DNA, and yet divide to produce cells serving different functions; basically how cells differentiate. And for that, she got a Nobel prize all to herself, which is no small feat either.

Becoming a Scientist

McClintock was born on June 16, 1902, in Hartford, Connecticut, USA. From age three until beginning school, she lived with her …read more

Maria Mitchell: The First Woman Astronomy Professor

On an October night in 1847, a telescope on the roof of the Pacific National Bank building on Nantucket Island was trained onto the deep black sky. At the eyepiece was an accomplished amateur astronomer on the verge of a major discovery — a new comet, one not recorded in any almanac. The comet, which we today know by the dry designator C/1847 T1, is more popularly known as “Miss Mitchell’s Comet,” named after its discoverer, a 29-year old woman named Maria Mitchell. The discovery of the comet would, after a fashion, secure her reputation as a scholar and a …read more

Disrupting The Computer Industry Before it Existed: Rear Admiral Grace Hopper

The feature of being easier to write than assembly is often seen as the biggest advantage of high-level programming languages. The other benefit that comes with them is portability. With high-level languages, algorithms can be developed independently from the underlying hardware. This allows software to live on once the hardware becomes obsolete.

The compiler was a concept that was met with resistance when it was first introduced. This was at a time when computers were custom-built machines bearing individual names like ENIAC, UNIVAC and Mark I. A time when the global demand for computers was estimated to be around five …read more

Rosalind Franklin Saw DNA First

It’s a standard science trivia question: Who discovered the structure of DNA? With the basic concepts of molecular biology now taught at a fairly detailed level in grade school, and with DNA being so easy to isolate that it makes a good demonstration project for school or home, everyone knows the names of Watson and Crick. But not many people know the story behind one of the greatest scientific achievements of the 20th century, or the name of the scientist without whose data Watson and Crick were working blind: Rosalind Franklin.

Born in London in 1920, Rosalind Elsie Franklin was …read more

Happy Ada Lovelace Day!

Today is Ada Lovelace Day, a day to celebrate and encourage women in the fields of science and technology. The day is named after Augusta Ada King-Noel, Countess of Lovelace, born Byron. (You can see why we just call her Ada Lovelace.) She was a brilliant mathematician, and the writer of what’s probably the first real computer program — it computed the Bernoulli series. At least according Charles Babbage, in correspondence to Michael Faraday, she was an “enchanted math fairy”. Not only a proto-coder, she wrote almost all of the existing documentation about Babbage’s computation engine. She’s a stellar example …read more
