There are many subjects I’d like to post about. As an autodidact I have a wide variety of interests coupled to a driving impulse to look outside the box marked “that’s all you need to know”. Art, music, literature, economics, business, research on Scripture, and science have been touched on in my posts. But because of the threat of tyranny on the horizon, I have been posting about matters crucial to life on this planet.
The situation on the ground is not looking up. This post, a break from my current posts, takes a look up with the help of the James Webb Space Telescope and astronomy.
After retiring at the end of last year I joined the Indiana Astronomical Society to learn astronomy. Through IAS I attended the following livestream: Exploring the Universe with the James Webb Space Telescope with Caty Pilachowski, Ph.D.
Caty Pilachowski is an observational astronomer, using large telescopes in Hawaii, Arizona, and Chile to study the chemical evolution of stars, specifically how the compositions of different populations of stars differ from each other due to different histories of star formation. She studies rainbows of starlight to identify and measure the signatures of different chemical elements to determine how much of those elements each star contains. Before joining the faculty at IU in 2001, Caty worked at the national observatory in Tucson, where she helped to build the 3.5 meter WIYN telescope that IU astronomers use for their research.

Is our Solar system currently safe? Are there any hidden dangers we might expect in the future?
The universe is a dynamic environment where collisions and close encounters play a significant role. Some were responsible for the birth of our planet Earth and life itself, and some nearly destroyed it.

“Abandon the urge to simplify everything, to look for formulas and easy answers, and to begin to think multidimensionally, to glory in the mystery and paradoxes of life, not to be dismayed by the multitude of causes and consequences that are inherent in each experience — to appreciate the fact that life is complex.” ― M. Scott Peck
“For the first time, people knew with certainty that there was more to the natural world than meets the eye.” [i]
The development of optical devices – telescopes, microscopes, and camera obscuras – enabled the curious in 17th century Europe to see beyond the boundaries of the naked eye. With enhanced vision, natural philosophers and artists were learning to see beyond what one was accustomed to seeing and beyond strongly held beliefs and theories of how things were. Acceptance that the world was very different than it seemed followed.
A patent for the “looker”, an instrument “for seeing things far away as if they were nearby“, was filed by a Dutch master lens grinder and spectacle maker Hans Lippershey in 1608. A backstory goes that children were playing with lenses in his spectacle shop. The kids noticed that a nearby weather vane looked larger when a pair of lenses were stacked. Lippershey’s patent was turned down on the grounds that the device was so simple that anyone could build one. Indeed, three Dutchmen had applied for the patent at the same time.
A year later, Italian natural philosopher, astronomer, and mathematician Galileo adapted his own “looker” to view the heavens. By grinding and polishing lenses and adding aperture stops, he improved the magnification up to about thirty times. With the modified spy glass, Galileo was looking for observational evidence to prove that the earth was going around the sun and not vice versa. He started his observations with the moon and found that it wasn’t a smooth uncorrupted surface as people were led to believe by the Catholic church. The Galilean moon had crater spots and irregular terrain.
“The prevailing astronomical tradition had long taught that the heavens were perfect and unchanging, in contrast to the earth, which seemed in constant upheaval. This claim derived from the simple observation that change was almost never observed in the heavens. Christian theology, inspired by this pagan Greek idea, had interpreted the consistency of the night sky in terms of sin and the fall.”[ii]
Galileo developed the scientific method and in so doing natural philosophy began to change from prevailing tradition accounts to experiment-justified and mathematically explained accounts. His revolutionary telescopic discoveries furthered the acceptance of the Copernican heliocentric system and eventually an unwanted acceptance into the Inquisition process. The crime: seeing what was there all along and not seeing what he was told to see.
Spectacle lens stacking was also behind the invention of the compound microscope about 1590. Three Dutch opticians or spectacle makers—Hans Jansen, his son Zacharias Jansen and Hans Lippershey are credit with credited with the invention. The curious would use the microscope to explore new unseen worlds. One such inquisitor was Dutch civil servant Antonie van Leeuwenhoek.
Leeuwenhoek, grinding and polishing his own lenses, began his pioneering observations of freshwater microorganisms in the 1670s. He effectively launched microbiology in 1674 as the first to observe bacteria and protozoa, thereby laying the foundations for the sciences of bacteriology and protozoology. His researches on lower animals refuted the doctrine of spontaneous generation.
(I find it so interesting that Leeuwenhoek started doing his microbiology work on his own, without grants and schooling in optics and biology. He examined a vast range of specimens -insects, canal water, cow’s eyes and dragonfly’s eyes, human body parts, and much more. He was determined to see beneath the surface and what was there all along. With the help of local drafters who drew the microscopic images, Leeuwenhoek passed his observations on to the Royal Society of London where they caused quite a stir.
Thecamera obscuraoptical device had been around for a long time – long before it was named. In his 1611 book Dioptrice, German astronomer Johannes Kepler coined the term camera obscura which means ‘dark chamber’ in Latin.
The instrument, up until the 16th century, typically took the form of a closed room with windows shuttered and a small hole in a blind or door. Light entered the room through the hole and cast an image onto a screen or onto the wall opposite the door. This type of dark room camera obscura was used by astronomers to make solar observations without damaging their eyes.
The ‘pinhole’ was later (mid-16th century) replaced with a convex glass lens, used in spectacles since the 13th century. The updated camera obscura made it possible to accurately draw the camera image by tracing outlines onto a paper screen. Through the lens and a light-controlling aperture diaphragm the projected image, smaller than actual size, was clear and bright with a concentration of color and a noticeable effect on color in deep shadow. Because this device provided a more accurate representation of the likeness of things and things not seen by the naked eye, it was of interest to surveyors, cartographers, topographers and painters, including Johannes Vermeer.
Small world. Born the same week of October 1632 as microscopist Antoine van Leewenhoek, Vermeer lived near Leewenhoek. The two Dutchmen lived on streets across from the small Delft Market Square. They may have known each other, but that is only conjecture as there is no evidence to support their relationship. They lived during the Dutch Golden Age, a time in Holland of economic, cultural, and scientific knowledge expansion. It was time of freedom from intellectual inquisitions.
(I recommend Laura J. Snyder’s Eye of the Beholder: Johannes Vermeer, Antoni van Leeuwenhoek, and the Reinvention of Seeing for more on the life and times and work of Vermeer and van Leewenhoek and the optical instruments behind the Scientific Revolution that made it possible to see “that there was more to the natural world than meets the eye.”)
Many artists at this time, wanting to depict more realistic images, were experimenting with optical devices such as mirrors and the camera obscuras. It Is not known that Vermeer used the camera obscura. Perhaps, based on the camera’s projected image, Vermeer created a shadowy image outlining the scene before painting. Artists at that time were keen on keeping their methods secret.
We can only guess at the use of a double-convex lens or the camera obscura for The Cavalier and the Young Woman. The scene is a wide-angle lens view. Note that the man is much larger than the woman which reflects an accurate depiction tending toward a photo realistic quality. Many artists at that time would paint both the man and the woman the same size based not on sight but on how things should be perceived.
Many Dutch homes, at the time of Vermeer, were filled with paintings depicting everyday life. Vermeer both collected and sold such paintings while running an inn that operated in the lower part of the family home. He painted up in the loft. At one point Vermeer and his wife Catherina had eleven children to support.
Vermeer is well-known for his depiction of individual women in quiet domestic scenes, most notably the mysterious Girl with The Pearl Earring. Was this Vermeer’s daughter?
Vermeer also captured the times. Natural philosophers were studying heaven and earth and Vermeer captured this in The Astronomer and The Geographer. Optical devices are required for both disciplines.
Vermeer’s interest in the natural world can be seen in his obsession with maps – depicted in nine of his paintings. See The Cavalier and the Young Woman for one example.
Vermeer began and ended his painting career with paintings of religious iconography: Christ in the House of Mary and Martha (1654-55) and Allegory of Catholic Faith (1670-74).
What were the natural philosophers thinking during this period? A couple of examples might reveal the range of thought.
“I think therefore I am” René Descartes believed that everything he knew, or believed he knew, came from his senses and sensory experience and was therefore suspect. Descartes “espoused an epistemology, or method of knowledge acquisition, that expressed mistrust in the senses, and placed primary value on reasoning from ideas found in the mind rather than from observations of nature.”[iii]
Francis Bacon defended the empirical study of nature and wanted to avoid bringing preconceived notions and prejudices into the findings. He argued for a cooperative and methodical procedure to keep knowledge from being subjected to the four idols of the mind that skewed findings off in a certain direction. He “rejected the claims of those who thought that all knowledge, even knowledge of the physical world, came primarily through human reason and not the senses.”[iv]
Natural philosophers like Descartes and Bacon investigated the natural world with an understanding of God as the Creator. They had views of spiritual reality and wanted views of physical reality. With the new optical devices they were able to see beyond the religious symbolism found in art, architecture, and the simplistic and even disparaging views of nature. Their investigations did not lead them to reject God. Instead, they saw science as a way of learning more about God.
Here’s Francis Bacon’s motivation for aggressively studying both God’s word and God’s world:
To conclude, therefore, let no man upon a weak conceit of sobriety or an ill-applied moderation think or maintain that a man can search too far, or be too well studied in the book of God’s word, or the book of God’s works, divinity or philosophy; but rather let men endeavor an endless progress or proficiency in both; only let men beware that they apply both to charity, and not to swelling; to use, and not to ostentation; and again, that they do not unwisely mingle or confound these learnings together.
Francis Bacon (1824). “The Works of Francis Bacon: Baron of Verulam, Viscount St. Albans, and Lord High Chancellor of England”, p.11
Bacon also said A little science estranges a man from God; a lot of science brings him back. A lot of science took place in the 17th century.
“At the moment, the scientific world was in the midst of a revolution. The so-called Scientific Revolution, today associated with Copernicus, Kepler, Bacon, Harvey, Galileo, and Newton was brought about in part by a new emphasis on empirical methods – making careful observations of the natural world – as opposed to the nonempirical, logical methods preferred by many medieval followers of Aristotle. No longer would the reliance on ancient texts, or armchair philosophizing about the world from a scholar’s study, be considered adequate. The clarion call of natural philosophers (for they were not yet called “scientists”) became “See for yourself”. [v]
With the aid of telescopes, microscopes, and camera obscuras the evidence of things not as yet seen – millions of stars, microbes, the color of shadows and much more of the natural world – came into view for natural philosophers and painters. They dared to see for themselves what was there before ancient texts and religious dogmas came out with authoritative views of the natural world. They saw what was there all along.
We have the Large Hadron Collider which “boosts particles, such as protons, which form all the matter we know. Accelerated to a speed close to that of light, they collide with other protons. These collisions
produce massive particles, such as the Higgs boson or the top quark. By measuring their properties, scientists increase our understanding of matter and of the origins of the Universe.”
We have positron emission tomography scan (PET scan), radiographic technique to examine the metabolic activity in various tissues especially in the brain.
We have functional magnetic resonance imaging (fMRI) which measures the small changes in blood flow that occur with brain activity.
