The Book of Seeds

April 26, 2019

Thanks to Alissa Simon, HMU Tutor, for today’s post.

Spring is upon us. Just as blossoms begin to show their strength, color, and vibrancy, so too the weather changes and begins to warm. All of the seasonal changes often add up to a change in attitude as well. Flowers, I believe, bring out the best of human nature, fostering images of beauty, strength, love, hope, and imagination. But where does the beauty begin? How does the flower take root and gain enough energy to grow their blooms?

Paul Smith begins his recent book The Book of Seeds; A Life-size Guide to Six Hundred Species from Around the World (2018) with the following lines:

“Seeds are amazing. They can travel thousands of miles across oceans and continents, and can live for hundreds of years. A seed no bigger than a pinhead can grow into the tallest living organism on the planet. The smallest seed can barely be seen with the naked eye; the largest is the size of a human head. Over a period of more than 300 million years, seeds have evolved into every size, shape, and color imaginable” (6).

All of that seems amazing when one considers how little we discuss seeds in comparison to how much time is spent on animals, even extinct animals such as dinosaurs. Often we fail to notice the same awe-inspiring capabilities from plants of the same time period – ones to which we still have access! Paul Smith continues:

“Plant life on land evolved a staggering 600 million years ago, with the ancestors of many of these early plants still extant today: the mosses, clubmosses, horsetails, and ferns. These species don’t produce flowers or seeds; instead, they reproduce through spores. It was not until approximately 240 million years later that the first primitive seed-bearing plants appeared, an adaptation that conferred numerous advantages for survival, including the capacity for sexual reproduction in the absence of water, the ability to disperse over long distances, and the adaptability to survive in a dormant state for long periods of time until the right conditions arose. Today, the vast majority of plant species (more than 80 percent) are found in the tropics, but even places as inhospitable as Antarctica and the Sahara Desert support seed-bearing plant species” (7).

Seeds have adapted many tricks to optimize their environments. For example, some seeds remain dormant for long periods of time waiting until the conditions are ripe for life. Smith explains that some seeds, particularly those in warm, wet environments, do not remain dormant. Instead of storing energy, they choose to sprout quickly and gain access to the immediate environmental benefits. Other seeds, like the coconut, float which enables them to travel greater distances to access better growing conditions. Many seeds may remain dormant for years. One of the greatest examples of this was found in the 1960s during an excavation at King Herod’s palace in Israel. A 2,000 year old date palm seed was found among the ruins and when planted, it grew normally.

More impressive than their amazing adaptations, however, is the important part that seeds play in determining human existence. Without plants that can be planted and cultivated as a food source, humans would have to remain hunter gatherers. Seeds, especially the ones that can be saved and transported, allow humans to move to a new place, or stay in one place. The ability to grow foods impacts social connectivity and health. Smith writes, “The adaptive leap that humans made from collecting grains and seeds to planting and harvesting them seems to have occurred in parallel in several different places” (18). This astounding idea – that multiple communities who did not know of each others’ existence arrived at cultivation simultaneously indicates something important about the nature of humans and of our interaction with the planet. Smith notes that around 9500 BCE Wheat, Barley, Pea, and Lentil “were domesticated in the Fertile Crescent – what is now Iran and Iraq” (18). From there, he continues:

“At around the same time, Rice was first cultivated in China, followed by Soybean. In the Andes, the Potato was domesticated around 8000 BCE, together with beans. In New Guinea, Sugarcane and the Yam appear in the archeological record about 7000 BCE. In Africa, Sorghum was domesticated in about 5000 BCE, and in Central America, Maize was first cultivated around 4000 BCE. Domestication of livestock occurred over a similar period of time. The transformation of wild plants into crops through artificial selection and breeding enabled human communities to establish themselves in villages, towns, and cities, and to flourish” (19).

While the history of seeds is astoundingly impressive (and seeds themselves are as diverse as imaginable), more importantly, however, may be the future of plants. Smith claims that plant diversity is of utmost importance since the majority of life on earth depends upon plants. He notes that we have studied relatively few, however. He claims that plants seem nondescript, but they have important roles in our daily lives. Smith ends his introduction with a quote by Aldo Leopold which underscores the point that humans would better serve themselves and the earth by adding a curious intelligence into their dealings with plants. He quotes, “If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering” (27).

I highly suggest thumbing through this massive collection of seeds. The diversity and colorful arrays are astounding. It will leave you with yet another reminder of the world’s vast richness.

Hippocrates on Education

April 19, 2019

Thanks to Alissa Simon, HMU Tutor, for today’s post.

After reading bits and pieces of Hippocrates’s writings, I am impressed by the amount of attention he pays to education. Though often called the “Father of Medicine,” Hippocrates also devoted a lot of time to understanding how people gain knowledge. In “The Book of Prognostics,” Hippocrates focuses on forming a patient prognosis, rather than a diagnosis or treatment of symptoms. Many diagnoses of his day included the idea that gods were involved in health. Instead, he sought to remove superstition from the field of medicine and turn it into a legitimate profession. In doing so, he not only revolutionized medicine, but the idea of how humans can learn from their environment. In other words, he revolutionized education itself.

In the “Book of Prognostics,” Hippocrates lists a number of maladies by symptom. Without naming any specific diseases, he dispels two important myths. First, he denies that any disease is sent by supernatural forces. Rather, he explains that diseases exist naturally and the physical human body participates in nature. This is part of his reason for avoiding common disease names, which often referenced deities or the supernatural. Second, he bases part of his evidence on other regions of the world. He writes, “One should likewise be well acquainted with the particular signs and the other symptoms, and not be ignorant how that, in every year, and at every season, bad symptoms prognosticate ill, and favorable symptoms good, since the aforesaid symptoms appear to have held true in Libya, in Delos, and in Scythia, from which it may be known that, in the same regions, there is no difficulty in attaining a knowledge of many more things than these; if having learned them, one knows also how to judge and reason correctly of them” (53). The corresponding footnote explains, “According to Galen, Hippocrates means here that good and bad symptoms tell the same in all places, in the hot regions of Libya, and the cold of Scythia, and the temperate of Delos” (53). He begins to widen the data set by including a more global view, which also gives him more information when offering a prognosis.

In “The Law,” Hippocrates expresses his disgust with the current state of medicine. While he claims that medicine is the most noble art, he laments the fact that it trails all of the other arts because it lacks accountability. Since no one had official training, anyone could call themselves a doctor and prescribe whatever they desired. He claims that “Such persons are like the figures which are introduced in tragedies, for as they have the shape, and dress, and personal appearance of an actor, but are not actors, so also physicians are many in title but very few in reality” (303). Hippocrates demands more accountability in his profession. He asks that more people treat it with academic rigor rather than mystical charms, powders, and gimmicks. He says that, much like medicine, instruction is also an art form. Hippocrates, as both student and teacher, then labels some advantages necessary for medical students. He writes that the student needs “a natural disposition; instruction; a favorable position for the study; early tuition; love of labor; leisure” (303). From these advantages, the student may develop the necessary skills of their chosen art. Furthermore, he believes that without leisure, or time spent in contemplation, the medical doctor cannot begin to piece together the the intricacies of the human body. Hippocrates demonstrates the fruit of contemplation and leisure throughout his books on medicine.

These lines sketch not only the study of medicine, but of the most fruitful education system as well. Any discipline requires love of labor, access to instruction, as well as contemplation. In “The Law,” Hippocrates continues, “First of all, a natural talent is required; for, when Nature opposes, everything else is in vain; but when Nature leads the way to what is most excellent, instruction in the art takes place, which the student must try to appropriate to himself by reflection, becoming an early pupil in a place well adapted for instruction. He must also bring to the task a love of labor and perseverance, so that the instruction taking root may bring forth proper and abundant fruits” (303). Hippocrates reminds us that any path towards excellence requires study and perseverance.

Female Cartographers

March 15, 2019

Thanks to Alissa Simon, HMU Tutor, for today’s post.

Last week’s blog took a look at Artemisia, an ancient female mariner. Despite the lack of discussion in print, women have spent time at sea, either in disguise or as themselves. Artemisia is only one historical example of a strong female capable of captaining her own ships. Unfortunately, many of the stories have been lost or buried in unread journal entries. As an example, a timeline of women at sea presented by the Mariners Museum begins in 1493 and notes how much more research is warranted in this area.

Mapmaking is another industry in which women have been all but elided. Ironically, according to Peter Barber, editor of The Map Book, “In the eighteenth century there were a surprisingly high number of female mapmakers” (212). In truth, it is difficult to find any map of history penned by a woman without digging deep. In much the same way that jobs of clerks and scribes were often denied to women, so too was cartography. Yet, there are pockets of history in which women combined skills of art and science in the form of maps. Barber continues, “In keeping with the eighteenth-century France’s enlightened attitude towards the position of women, this map predicting the eclipse of 1764 was produced by three women: Madame le Pauté Dagelet, Madame Lattré and Elisabeth Claire Tardieu” (220). This map emerged during the boom of the Enlightenment and clearly demonstrates a juncture between science and art. Barber continues, “The map has a more scientific appearance than earlier maps but the title cartouches are very decorative and impart a good balance of the artistic and scientific” (220). The map’s right-hand side incorporates background information regarding the eclipse. Embellishments draw attention to the subject (solar eclipse) and to Madame le Pauté Dagelet as author of the information. Barker also notes, however, that not much is known about her other than she was “an astronomer and member of the Académie Royale des Sciences (Béziers)” (220). Madame Lattré, the engraver, however, was part of a “well-established dynasty of map makers,” (220). No mention is made of how many maps Madame Lattré might have made, or if she officially contributed to the illustrious career of her husband’s map-making business.

Despite their involvement, little was known about the impact that women have had on cartography until recently. With the advance of technology, information can be parsed more quickly which greatly assists our ability to research topics previously thought obscure, such as female cartography. As an example, a current article from CityLab chronicles librarian Alice Hudson’s research in which she restricts herself to the last 300 years in North America alone because she had found thousands of maps by women. In the article, Hudson explains how tricky it is to discover the true identity of the mapmaker. For example, women often used initials rather than full names to hide their identity. As a further complication, indexes only mention male-owned businesses, and rarely the cartographers themselves.

During World War II, while men were sent off to war, women began to fill the gaps in some geography and engineering courses. In the first year alone, Chicago’s Geography Department witnessed more than two hundred women complete the course. After the war, many women went back to their domestic lives, but Marie Tharp continued on with graduate school in order to earn a PhD. She then became a research assistant at Columbia University working alongside Bruce Heezen. In her research, she discovered a large rift along the Atlantic, now known as the Mid-Atlantic Rift. After a year, she succeeded in convincing him about the existence of plate tectonics, however, she still needed his approval and name in order to distribute the information since it was Heezen’s name that legitimized the research.

Today, their map is considered to be one of the most influential maps of the 20th century. Though much of Tharp’s career was marked by limitations, she persevered. Though unable to be on job sites and out in the field, she learned how to parse data efficiently and intelligently. She also found a male colleague willing to listen to her ideas. She partnered with Bruce Heezen for almost thirty years, in part because he saw the brilliance of her work. According to Encyclopedia.com, Tharp was finally able to go to sea in 1965, not through her own institution (which still prohibited women from working at sea), but through a program offered by Duke University. Encyclopedia.com continues, “Largely invisible as a researcher early in her career, Tharp gained recognition for her geographic insights and cartographic skills later in life. She received awards from the Geography and Map Division of the Library of Congress and Woods Hole Oceanographic Institution, as well as the first annual Lamont-Doherty Earth Observatory Heritage Award in 2001. Four years later, Lamont created the Marie Tharp Visiting Fellowship program to aid promising women researchers.”

Along with female mariners, the field of cartography offers rich potential to those willing to do a little digging.

Math According to Archimedes and Hardy

February 1, 2019

Thanks to Alissa Simon, HMU Tutor, for today’s post.

I have a number of questions still rumbling around after Harrison Middleton University’s January Quarterly Discussion. We read Archimedes’ Sand Reckoner and G. H. Hardy’s Mathematician’s Apology. I put these two pieces together because I am interested in mathematical discourse separated by thousands of years. More than time, however, they also came from different parts of the world, encountered very different technological advances, and lived immensely different lifestyles. Archimedes of Syracuse was a Greek mathematician and inventor who lived around 287-212 BC. Hardy, on the other hand, was born in 1877 in England and showed an early aptitude for numbers. He continued with math through college when he became largely interested in “pure mathematics” which, he claimed, is more noble than practical math. So, my first question is whether or not Archimedes’ Sand Reckoner corresponds to pure math, or practical math?

In The Sand Reckoner (which I have written about before), Archimedes sets out to demonstrate that math has strategies to break down something as large and abstract as the measure of the universe, or the grains of sand on earth. His proof begins with rather large assumptions, such as “I suppose the diameter of the sun to be about 30 times that of the moon and not greater.” Initially, I did not understand why Archimedes would base a proof upon such unknowns. However, I have always thought that the exercise was more to inspire imagination than prove an actuality. And now, based upon conversation during the Quarterly Discussion, I see that Archimedes wanted not just to inspire imagination, but to demonstrate the potential of math. He was explaining that math functions on strategies which engenders new information. This would be important, of course, living in a time when math was largely unknown and therefore, seen as untrustworthy. So, to me, The Sand Reckoner is not a proof of any one thing, but a proof of math itself. He asks his king, other educators, and perhaps his community to believe in the potential of math and to contemplate questions of great size.

Jumping forward to Hardy’s piece, then, he draws a very decisive line between practical mathematicians and pure mathematicians. Practical math builds things like bridges and steam engines. Pure math contemplates greatness. For some reason, Hardy’s differentiation always brings me back to Archimedes, who built levers and invented all sorts of practical things, but yet also contemplated the universe. Does the mathematician who builds the bridge not also dwell upon other possibilities? Surely not all of them do, but I find Hardy’s approach very severe and limiting. I am not sure if his words are meant to inspire others to attempt a career in math, or to explain to the masses how little they actually know. Either way, I feel that the work fails when placed next to something like Archimedes’ proof which shows math’s potential rather than belabors the value of ambitious men. Perhaps, though, my perspective is naive, since I do not grasp much of the math that would place me in this elite group.

Clearly Hardy values creative thought over any other pursuit. I can identify with this, but I wonder if his criticisms speak to moral dilemmas of his day. Hardy wrote A Mathematician’s Apology in 1940. I have to think that war-time inventions must have been on his mind when he differentiated between practical and pure mathematics. And yet again, I return to thinking about Archimedes who built many machines of war such as the Archimedes Claw and catapults. Does this remove him from the rank of pure mathematician (if he was ever considered such)? In theory, I believe that I understand Hardy’s point. In fact, I relish the idea that a life of creative thought or philosophical discourse is as worthy as shipbuilding. This would justify my own life as well. However, it seems rarer that society allows such thinking to exist. Rather, society is structured in a way in which we must all pay for food and shelter, and creative thought does not pay. I think that perhaps Hardy might have been trying to tell us, the public, that we should value creativity more than we currently do.

Additionally, his message does not address morality at all, which the group found interesting. I wonder how Hardy would tie ambition to morality. He glories in the uselessness of math because it cannot be tied to evil. He writes,

“If the theory of numbers could be employed for any practical and obviously honourable purpose, if it could be turned directly to the furtherance of human happiness or the relief of human suffering, as physiology and even chemistry can, then surely neither [Carl Friedrich] Gauss nor any other mathematician would have been so foolish as to decry or regret such applications. But science works for evil as well as for good (and particularly, of course, in times of war); and both Gauss and lesser mathematicians may be justified in rejoicing that there is one science, at any rate, and that their own, whose very remoteness from ordinary human activities should keep it gentle and clean.”

According to Hardy, pure math never filters into practical applications. I find this reasoning illogical, though since again, levers as created by Archimedes were once thought impossible and are now the foundation of much greater machines. In my mind, the lever was purely theoretical at one point and is now elementary science. Also, once public, how can anyone protect the ways in which their work will be used (or not used)? How can Hardy surmise that the pure math of today will not be the applied math of tomorrow? And does its application make it any less pure?

As always, I am indebted to a wonderful group who wanders through these questions with me. The next Quarterly Discussion will be held in April 2019. For more information email asimon@hmu.edu. I look forward to hearing from you!
