The Art of the Cosmos : Visions from the Frontier of Deep-Space Exploration
Hundreds of deep space missions since the 1960s have captured stunning photographs of the cosmos.Many of these scientific images can also be classified as art.This book highlights more than 100 examples, revealing the splendor of our universe. This book is a gallery of human accomplishment that celebrates the scientists and engineers who push civilization-including the ways that we produce and experience art-beyond the physical limits of our planet.The photographs, selected by Dr. Jim Bell, represent some of the finest examples of the art of deep space exploration, most of them involving high-tech robotic emissaries.The images are loosely organized by distance from the Earth, so that readers will slowly travel on a journey farther and farther away from home, ultimately voyaging out to vistas of the farthest-known places in the universe.

Celestial Calculations : A Gentle Introduction to Computational Astronomy
How to predict and calculate the positions of stars, planets, the sun, the moon, and satellites using a personal computer and high school mathematics. Our knowledge of the universe is expanding rapidly, as space probes launched decades ago begin to send information back to earth.There has never been a better time to learn about how planets, stars, and satellites move through the heavens.This book is for amateur astronomers who want to move beyond pictures of constellations in star guides and solve the mysteries of a starry night.It is a book for readers who have wondered, for example, where Saturn will appear in the night sky, when the sun will rise and set, or how long the space station will be over their location.In Celestial Calculations, J. L. Lawrence shows readers how to find the answers to these and other astronomy questions with only a personal computer and high school math.Using an easy-to-follow step-by-step approach, Lawrence explains what calculations are required, why they are needed, and how they all fit together. Lawrence begins with basic principles: unit of measure conversions, time conversions, and coordinate systems.He combines these concepts into a computer program that can calculate the location of a star, and uses the same methods for predicting the locations of the sun, moon, and planets.He then shows how to use these methods for locating the many satellites we have sent into orbit.Finally, he describes a variety of resources and tools available to the amateur astronomer, including star charts and astronomical tables.Diagrams illustrate the major concepts, and computer programs that implement the algorithms are included.Photographs of actual celestial objects accompany the text, and interesting astronomical facts are interspersed throughout. Source code (in Python 3, JAVA, and Visual Basic) and executables for all the programs and examples presented in the book are available for download at https://CelestialCalculations.github.io.

How do you thread the bobbin thread?
To thread the bobbin thread, first, place the spool of thread on the spool pin and secure it with a spool cap. Then, guide the thread through the bobbin winding tension disc and wrap it around the bobbin a few times. Next, place the bobbin onto the bobbin winder and push it to engage the winding mechanism. Hold the end of the thread and start the machine to wind the bobbin until it is full. Finally, trim the excess thread and remove the bobbin from the winder.

Why is the upper thread not pulling the lower thread?
There are several reasons why the upper thread may not be pulling the lower thread. One common reason is that the upper thread tension may be too loose, causing the upper thread to not have enough tension to pull the lower thread. Another reason could be that the upper thread is not properly threaded through the tension discs or the needle, leading to a lack of tension. Additionally, there may be a problem with the bobbin, such as it being inserted incorrectly or the bobbin tension being too tight, preventing the lower thread from being pulled up properly.

How can I cut a thread without a thread cutter?
You can cut a thread without a thread cutter by using a pair of scissors or a sharp knife. Simply hold the thread taut and carefully cut it with the scissors or knife. Be cautious to avoid cutting yourself or damaging the fabric. Another option is to use your teeth to bite through the thread if you do not have any tools available.

Why do we say "red thread" instead of "green thread"?
The phrase "red thread" is often used to refer to a common theme or connection that runs through a series of events or ideas. This phrase may have originated from the ancient Chinese legend of the "red string of fate," which is said to connect people who are destined to meet or be together. The color red is often associated with passion, fate, and significance, which may be why it is used in this phrase. Additionally, red is a bold and attention-grabbing color, making it a fitting choice for a phrase that signifies a strong and meaningful connection.

How do you determine the thread pitch without a thread gauge?
To determine the thread pitch without a thread gauge, you can use a ruler to measure the distance between the peaks of the threads. Then, count the number of peaks within a one-inch span. Divide the number of peaks by the measurement in inches to determine the thread pitch. Another method is to use a pitch gauge, which is a tool with a series of blades that can be matched against the threads to determine the pitch. Additionally, you can compare the threads to a known thread pitch to visually estimate the pitch.
