Today I had the great pleasure of hearing Susan Kilrain speak at Technikmuseum Speyer.

I have to say, of all the astronauts I have personally heard giving talks, Kilrain was by far the most charismatic, most exciting and most gifted public speaker- no surprise, of course, seeing as she became a successful motivational speaker since her career as a pilot and astronaut.

Born in 1961 in Augusta, Georgia as one of 9 children, she seized every opportunity to make her dream of becoming an astronaut a reality. Already earning her private pilot's license in high school, she became an aerospace engineer and joined the Navy with the goal of becoming a test pilot and, eventually, a space shuttle pilot.

She spoke of her experience as a woman in a man's world, who did not only have to prove her own, personal ability, but that of all women. With 3000 flying hours under her belt, she was selected as part of the 15th Astronaut Training Group. She was the pilot on both STS-83, which due to technical problems was aborted with only 3 days of time in space, as well as STS-94, the reflight of the aborted mission. This remains the only time in spaceflight history that two missions were flown by an identical crew.

Kilrain told her story with passion and humor, a perfect balance of funny anecdotes and simple facts. I have visited many talks at the museum, and I have never seen the audience so absorbed and having so much fun. Whether it was the story of flying the notorious Grumman F-14 Tomcat with engine-, hydraulics- and instrument failures or an unfortunate yet funny appearance in newsreel footage; she has a real talent of stirring excitement. Not even one child was making a fuss in the stuffy auditorium as they all sat listening intently to her 1 hour long talk- even if they didn't speak English!

The moment that most outstandingly proved her ability to inspire was when during the Q&A a young girl asked for advice for herself and her little sister on becoming astronauts. Her response was funny, practical and echoed real-life experience: Do well in school, keep your body healthy by playing outside and being physical rather than sitting down with screens, and learn how to work in a team even if you don't get along ("You can start with your sister!" got one of the many laughs that afternoon).

Of course she didn't leave without paying Europe's largest space exhibit, "Apollo & Beyond" at the Technikmuseum, the biggest compliment it could perhaps receive: It is the greatest collection of space exploration memorabilia she has ever seen in one place! Even the Smithsonian apparently pales in comparison. Coming from an astronaut who has seen it all, that must have been a great joy for curator Gerhard Daum to hear. It was even her first chance since being a pilot of the Columbia that she got to sit in the pilot's seat of a space shuttle: During an interview inside the museum's Buran OK-GLI. (pictures will follow)

In the end she took time to sign copies of her book An Unlikely Astronaut, leaving having no doubt inspired many children to follow in her incredible footsteps.

April 14, Xi'an, China, Shaanxi History Museum, Qin and Han Dynasties Branch (Part 3 – Innovations and Philosophies):

(Edit: sorry this post came out so late, I got hit by the truck named life and had to get some rest, and this post in itself took some effort to research. But anyway it's finally up, please enjoy!)

A little background first, because this naming might lead to some confusions.....when you see location adjectives like "eastern", "western", "northern", "southern" added to the front of Zhou dynasty, Han dynasty, Song dynasty, and Jin/晋 dynasty, it just means the location of the capital city has changed. For example Han dynasty had its capital at Chang'an (Xi'an today) in the beginning, but after the very brief but not officially recognized "Xin dynasty" (9 - 23 AD; not officially recognized in traditional Chinese historiography, it's usually seen as a part of Han dynasty), Luoyang became the new capital. Because Chang'an is geographically to the west of Luoyang, the Han dynasty pre-Xin is called Western Han dynasty (202 BC - 8 AD), and the Han dynasty post-Xin is called Eastern Han dynasty (25 - 220 AD). As you can see here, in these cases this sort of adjective is simply used to indicate different time periods in the same dynasty.

Model of a dragonbone water lift/龙骨水车, Eastern Han dynasty. This is mainly used to push water up to higher elevations for the purpose of irrigation:

Model of a water-powered bellows/冶铁水排, Eastern Han dynasty. Just as the name implies, as flowing water pushes the water wheel around, the parts connected to the axle will pull and push on the bellows alternately, delivering more air to the furnace for the purpose of casting iron.

The Nine Chapters on the Mathematical Art/《九章算术》, Fangcheng/方程 chapter. It’s a compilation of the work of many scholars from 10 th century BC until 2 nd century AD, and while the earliest authors are unknown, it has been edited and supplemented by known scholars during Western Han dynasty (also when the final version of this book was compiled), then commented on by scholars during Three Kingdoms period (Kingdom of Wei) and Tang dynasty. The final version contains 246 example problems and solutions that focus on practical applications, for example measuring land, surveying land, construction, trading, and distributing taxes. This focus on practicality is because it has been used as a textbook to train civil servants. Note that during Han dynasty, fangcheng means the method of solving systems of linear equations; today, fangcheng simply means equation. For anyone who wants to know a little more about this book and math in ancient China, here’s an article about it. (link goes to pdf)

Diagram of a circle in a right triangle (called “勾股容圆” in Chinese), from the book Ceyuan Haijing/《测圆海镜》 by Yuan-era mathematician Li Ye/李冶 (his name was originally Li Zhi/李治) in 1248.  Note that Pythagorean Theorem was known by the name Gougu Theorem/勾股定理 in ancient China, where gou/勾 and gu/股 mean the shorter and longer legs of the right triangle respectively, and the hypotenuse is named xian/弦 (unlike what the above linked article suggests, this naming has more to do with the ancient Chinese percussion instrument qing/磬, which is shaped similar to a right triangle).  Gougu Theorem was recorded in the ancient Chinese mathematical work Zhoubi Suanjing/《周髀算经》, and the name Gougu Theorem is still used in China today.

Diagram of the proof for Gougu Theorem in Zhoubi Suanjing. The sentence on the left translates to "gou (shorter leg) squared and gu (longer leg) squared makes up xian (hypotenuse) squared", which is basically the equation a² + b² = c². Note that the character for "squared" here (mi/幂) means "power" today.

This is a diagram of Zhang Heng’s seismoscope, called houfeng didong yi/候风地动仪 (lit. “instrument that measures the winds and the movements of the earth”).  It was invented during Eastern Han dynasty, but no artifact of houfeng didong yi has been discovered yet, this is presumably due to constant wars at the end of Eastern Han dynasty.  All models and diagrams that exist right now are what historians and seismologists think it should look like based on descriptions from Eastern Han dynasty. This diagram is based on the most popular model by Wang Zhenduo that has an inverted column at the center, but this model has been widely criticized for its ability to actually detect earthquakes. A newer model that came out in 2005 with a swinging column pendulum in the center has shown the ability to detect earthquakes, but has yet to demonstrate ability to reliably detect the direction where the waves originate, and is also inconsistent with the descriptions recorded in ancient texts. What houfeng didong yi really looks like and how it really works remains a mystery.

Xin dynasty bronze calipers, the earliest sliding caliper found as of now (not the earliest caliper btw). This diagram is the line drawing of the actual artifact (right).

Ancient Chinese "Jacquard" loom (called 提花机 or simply 花机 in Chinese, lit. "raise pattern machine"), which first appeared no later than 1st century BC. The illustration here is from the Ming-era (1368 - 1644) encyclopedia Tiangong Kaiwu/《天工开物》. Basically it's a giant loom operated by two people, the person below is the weaver, and the person sitting atop is the one who controls which warp threads should be lifted at what time (all already determined at the designing stage before any weaving begins), which creates patterns woven into the fabric. Here is a video that briefly shows how this type of loom works (start from around 1:00). For Hanfu lovers, this is how zhuanghua/妆花 fabric used to be woven, and how traditional silk fabrics like yunjin/云锦 continue to be woven. Because it is so labor intensive, real jacquard silk brocade woven this way are extremely expensive, so the vast majority of zhuanghua hanfu on the market are made from machine woven synthetic materials.

Chinese purple is a synthetic pigment with the chemical formula BaCuSi2O6. There's also a Chinese blue pigment. If anyone is interested in the chemistry of these two compounds, here's a paper on the topic. (link goes to pdf)

A list of common colors used in Qin and Han dynasties and the pigments involved. White pigment comes from chalk, lead compounds, and powdered sea shells; green pigment comes from malachite mineral; blue pigment usually comes from azurite mineral; black comes from pine soot and graphite; red comes from cinnabar; ochre comes from hematite; and yellow comes from realgar and orpiment minerals.

Also here are names of different colors and shades during Han dynasty. It's worth noting that qing/青 can mean green (ex: 青草, "green grass"), blue (ex: 青天, "blue sky"), any shade between green and blue, or even black (ex: 青丝, "black hair") in ancient Chinese depending on the context. Today 青 can mean green, blue, and everything in between.

Western Han-era bronze lamp shaped like a goose holding a fish in its beak. This lamp is interesting as the whole thing is hollow, so the smoke from the fire in the lamp (the fish shaped part) will go up into the neck of the goose, then go down into the body of the goose where there's water to catch the smoke, this way the smoke will not be released to the surrounding environment. There are also other lamps from around the same time designed like this, for example the famous gilt bronze lamp that's shaped like a kneeling person holding a lamp.

Part of a Qin-era (?) clay drainage pipe system:

A list of canals that was dug during Warring States period, Qin dynasty, and pre-Emperor Wu of Han Han dynasty (475 - 141 BC). Their purposes vary from transportation to irrigation. The name of the first canal on the list, Hong Gou/鸿沟, has already become a word in Chinese language, a metaphor for a clear separation that cannot be crossed (ex: 不可逾越的鸿沟, meaning "a gulf that cannot be crossed").

Han-era wooden boat. This boat is special in that its construction has clear inspirations from the ancient Romans, another indication of the amount of information exchange that took place along the Silk Road:

A model that shows how the Great Wall was constructed in Qin dynasty. Laborers would use bamboo to construct a scaffold (bamboo scaffolding is still used in construction today btw, though it's being gradually phased out) so people and materials (stone bricks and dirt) can get up onto the wall. Then the dirt in the middle of the wall would be compressed into rammed earth, called hangtu/夯土. A layer of stone bricks may be added to the outside of the hangtu wall to protect it from the elements. This was also the method of construction for many city walls in ancient China.

A list of the schools of thought that existed during Warring States period, their most influential figures, their scholars, and their most famous works. These include Confucianism (called Ru Jia/儒家 in Chinese; usually the suffix "家" at the end denotes a school of thought, not a religion; the suffix "教" is that one that denotes a religion), Daoism/道家, Legalism (Fa Jia/法家), Mohism/墨家, etc.

The "Five Classics" (五经) in the "Four Books and Five Classics" (四书五经) associated with the Confucian tradition, they are Shijing/《诗经》 (Classic of Poetry), Yijing/《易经》 (also known as I Ching), Shangshu/《尚书》 (Classic of History), Liji/《礼记》 (Book of Rites), and Chunqiu/《春秋》 (Spring and Autumn Annals). The "Four Books" (四书) are Daxue/《大学》 (Great Learning), Zhongyong/《中庸》 (Doctrine of the Mean), Lunyu/《论语》 (Analects), and Mengzi/《孟子》 (known as Mencius).

And finally the souvenir shop! Here's a Chinese chess (xiangqi/象棋) set where the pieces are fashioned like Western chess, in that they actually look like the things they are supposed to represent, compared to traditional Chinese chess pieces where each one is just a round wooden piece with the Chinese character for the piece on top:

A blind box set of small figurines that are supposed to mimic Shang and Zhou era animal-shaped bronze vessels. Fun fact, in Shang dynasty people revered owls, and there was a female general named Fu Hao/妇好 who was buried with an owl-shaped bronze vessel, so that's why this set has three different owls (top left, top right, and middle). I got one of these owls (I love birds so yay!)

And that concludes the museums I visited while in Xi'an!

🇺🇸 Before purchasing the iconic ICQ Messenger from Mirabilis, AOL Inc. had already developed its own internet messaging tool. Released in May 1997 as a stand-alone download for Microsoft Windows, AIM (AOL Instant Messenger) quickly became the go-to platform for online communication. Created by American Online Inc., AIM used the OSCAR and TOC protocols to connect users in real time, becoming a cultural phenomenon by the late 1990s.

💾 At its peak, AIM had the largest share of the instant messaging market in North America, particularly in the United States, where it held 52% of the market as of 2006. This figure excludes other AOL-related instant messaging software like ICQ and iChat. AIM's main competitors included ICQ (which AOL acquired in 1998), Yahoo! Messenger, and MSN Messenger. AOL had a notable rivalry with PowWow and Microsoft, sparking the "chat wars" in 1999.

🚶‍♂️ The AIM mascot, designed by JoRoan Lazaro, debuted with the first release in 1997. This yellow stickman-like figure, known as the "Running Man," appeared on all AIM logos and wordmarks and was always featured at the top of the buddy list.

👩‍🎓🧑‍🎓 AIM was particularly popular among teens and college students in the United States and beyond. Its away message feature allowed users to share their whereabouts, thoughts, and plans with friends, making it a staple of daily digital interaction. AIM wasn't just a messaging app; it was a way of life.

📉 Despite its early success, AIM's popularity began to decline in the 2010s. The rise of Gmail's Google Talk, the advent of SMS, and the explosive growth of social networks like Facebook led to a decrease in AOL subscribers. AIM's fall from grace is often compared to other once-dominant services like Myspace.

📆 In June 2015, AOL was acquired by Verizon Communications, which later merged AOL and Yahoo into Oath Inc. Unfortunately, on December 15, 2017, AIM was discontinued, marking the end of an era.

💔 Though AIM is no longer with us, its impact on digital communication remains unforgettable. It paved the way for the instant messaging services we rely on today, leaving behind a legacy of nostalgia and innovation.

A few more pictures from my visit to the Col. James M. Schoonmaker, a freighter museum ship that began her life at Great Lakes Engineering Works of Ecorse, Michigan, in 1911. She carried coal on her maiden voyage from Toledo, Ohio to Sheboygan, Wisconsin.

She was actively sailing the Great Lakes until 1980, and of course she was updated and refitted to work for so many decades. But a lot of furniture on board is original: they never bothered to replace her apparently indestructible, very heavy wood furniture from before the Great War. You wouldn't know it was so old. The table and chairs are 1911 orginals, the captain's cabin and few guest rooms are still nicely appointed.

Tamagotchi hits a museum in Sweden! Otherwise known as Tekniska Museet, the Museum of Technology located in Stockholm, Sweden. The museum is the largest museum of technology, has an exhibit with vintage technology, which includes a display of the original Nintendo Game Boy, some games, and a Tamagotchi Connection, it looks like a V2 Clear Pink shell. It is interesting to see the sign mention Tamagotchi and the year of 1997, but show a device from 2005.

I've recently decided to take my Star Wars modern AU and give it a plot and as I've been thinking about it I wrote a short scene that takes place somewhat close to the beginning middle-ish. Unfortunately, I do not want to spoil the story so this scene is without context, but I'll post it here anyways for anyone who wants to read it.

There were no lectures in the Fett car that night. Only silence, though it was sometimes interrupted by the crunching of rocks on the asphalt road against the car’s tires. Omega huddled in the back seat, trying to ignore the glare Crosshair was giving her from the rearview mirror. Out of all her brothers, he was the angriest, which was not really very surprising. Crosshair tended to be like that. His anger was like ice—cold, hard, and long-lasting. Omega knew it could be months before he stopped being mad. She could even be done with her sentence—three months of grounding plus an extra month of chores—before Crosshair even began to stop being angry. Sometimes she wished he wasn’t like that. But it was just a testament to his loyalty—loyalty that kept him with Omega and her brothers instead of letting him roam off around the world like Omega knew he wanted to.  She hoped someday he would get to travel. He had told her once, in the strictest confidence, that he wanted to visit every country. So far, he had only been to three. Omega had been curious after he shared that with her, and she had snuck out his passport while he had been sleeping. Two stamps. One to Afghanistan, and the other to Costa Rica. The former had been to visit a recovering Echo. The latter had been for his never-spoken-of time working for the Empire. Omega usually liked Crosshair’s loyalty. But not now. Now it would mean holding onto his anger. There wouldn’t be any late-night movies or conversations between them for a while. Omega curled her legs up to her chest and hugged her knees. It would be fine. She’d get through this.
