Science History
Tomorrow is Sunday, and as I prepare to mount my plastic pulpit I will take as my text the introduction to Chapter 5 (Complex Numbers) of A Survey of Modern Algebra by Birkhoff&Mac Lane. This is a classic and accessible work, first published in 1941, which brought to the American-speaking world what was previously locked up in Van der Waerden’s Moderne Algebra (1931). The chapter opens with the definition of a complex number and the field C [1], and then continues:
We owe the above definition not to divine revelation, but to simple algebraic experimentation. First, it…
Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House, so why couldn't Darwin have done it too? A Journal of Biology article argues that Darwin's background, influences and research focus gave him a viewpoint that prevented him from interpreting the evidence that was all around him, even in his own work.
Moravian priest and scientist Gregor Mendel (1822 - 1884) studied clear-cut, inherited traits in pea plants, which he grew in the monastery gardens in Brno. Mendel showed that trait inheritance follows simple…

Merriam-Webster's dictionary says the word 'evolution' originated in 1622 and derives from the Latin evolutio, "unrolling, from", as in a parchment, and this is actually the perfect way to think of both Darwin and Evolution in their context.
Pedantics will note that Darwin used the word 'evolved' and not 'evolution' in Origin of Species, which seems a little picayune - there are good reasons he did not use it and only popular context demanded he include it by the sixth volume of Origin of Species, though he clearly preferred "descent with modification."
In a…

Hildegard von Bingen (1098-1179) was a remarkable woman. At a time when few women wrote, Hildegard, known as "Sybil of the Rhine", produced major works of theology, medicine and visionary writings. Hildegard composed music and spoke of Christ as God's song.
When few women were accorded respect, she was consulted by and advised bishops, popes, and kings. In medicine she used the curative powers of natural objects for healing and wrote treatises about natural history and medicinal uses of plants, animals, trees and stones. Her scientific books contain more than 2,000 remedies and health…
This is the year of Darwin (yes, yes, it’s also the year of astronomy, I know), and especially this week -- around the date of Chuck’s birth -- we are seeing a spike of events, radio and tv pieces, and printed articles. (Expect a second peak in November, for the anniversary of the publication of Origin of Species.)
One of the most schizophrenic treatments of the topic surely is the one published this week by Forbes magazine. They have a number of solid pieces by recognized scientists and science writers (for instance by evo-devo researcher Sean Carroll, philosopher …
One testament to the pervasive nature of evolution is that so many varied groups, even ones in opposition to each other, found an endorsement in his work. Proponents of eugenics, slavery and even Hitler could rationalize their views saying it was just evoluti0n while abolitionists saw just the opposite.
None of that was what Darwin had in mind, of course, and a new book by Darwin historians seeks to clarify our understanding of Darwin's path to human evolution by restoring the moral core of Darwin's work, placing it in its lost historical context. The authors say that…
Recently I read on this site Massimo Pigliucci’s articles on Hard and Soft Science. As usual, though, I at first sailed over the main theme, and picking up one or two phrases went off on one of my tangents. The first of these phrases was:
the long interval on the question of the nature of gravity between Newton and Einstein.
which led me to think that:Sometimes delays in science are not what they seem.
Take a butterfly: the chrysalis may seem inert, but there is a tremendous amount of cellular reconstruction going on to turn a caterpillar into a butterfly.…

Do you know the name of the first computer game? I confess I didn't and I learned programming on a Univac 1100/62 so I am a lot closer to the origination date of computer games than most people who will read this.
I assumed it was a kind of punchcard-loaded word game, like a 1960s Leather Goddesses of Phobos only without the divine genius of Dostoevsky that game possessed, but the history of video games is much more elaborate than that.
So depending on how you look at it, the first computer game may be a Brookhaven tennis game that recently turned 50; as you will see, it looked…
In the latest Vanity Fair is a brilliant piece of journalism, Goodbye to All That: An Oral History of the Bush White House by Cullen Murphy and Todd Purdum. In a fun, easy-to-read format, it tells some basic truths I had never read before. Here are two examples:
Matthew Dowd, Bush’s pollster and chief strategist for the 2004 presidential campaign:
When Abu Ghraib happened, I was like, We’ve got to fire Rumsfeld. Like if we’re the “accountability president,” we haven’t really done this.We don’t veto any bills. We don’t fire anybody. I was like, Well, this is a disaster, and we’re going to hold…

One of the things I enjoyed most about my time at Yale was the history of the place. I was pleasantly surprised to discover the famous scientists that worked there, including Lederberg, Tatum, Altman, Palade, Gilman etc. It gave me a sense of being part of a long tradition, part of something important. But most interesting, to me, was that George Evelyn Hutchinson spent his career there. Hutchinson is best known as the founder of Limnology, but truly he was a renaissance man, cognizant of many fields of arts and sciences. He served as mentor to many future ecologists, including Robert…
