The early nineteenth century saw tremendous advances in chemistry, with scientists leading teams all across the world to improve both science in general and industrial processes in particular. Leading the charge to improve rubber compounds was Charles Goodyear (born on this day, December 29, 1800, died July 1, 1860) who devoted his life and health to improving rubber compounds. Self taugh Goodyear ran a hardware store in Philadelphia and realized early that improved rubber goods would transform manufacturing.
He toyed with the chemistry of rubber manufacturing for two decades before hitting upon heating the rubber as the most important part of the process by accident. He was awarded a patent for vulcanizing rubber in 1844 for his efforts, though he still did not fully understand the process or what exactly was happening. Enduring backruptcy, jail, and personal tragedy, Goodyear died at the age of 59, collapsing at the news of his daughter’s death and never recovering.
The verb vulcanize was coined between 1820-1844 (several disputed dates are offered) to describe the process of changing something by adding heat or fire, from Vulcan, the Roman god of Fire. By 1846, the word was in wide circulation thanks to Goodyear’s patent. The company that bears his name today was actually founded almost 40 years after his death in honor of his contributions to the science of rubber compounds but also to capitalize on his fame and reputation. Etymologically, the name Vulcan (Volcānus or Vulcānus) has unclear origins. Some liguists connect the name with the Cretan god Velchanos, while others dispute this with no clear etymology. Vulcan’s earliest temple in Rome dates to 8th century BCE.

Memories of Gonder prior to Timket 2015. A traditional dancer at one of Gonder’s more famous cultural restaurants. The Tej made it all a blur but I had the presence of mind to pull out the xT1 and go up to some extreme ISO to try to make this pic. I am always inspired by Eskesta especially when done by some of the most beautiful woman on the planet… #Ethiopia #Ethiopian #EthiopianOrthodoxChurch #EthiopianOrthodoxTewahedoChurch #Timket #Timket2015 #culturaldance #Eskesta #Habesha #HabeshaCulture #PhotoToaster #fuji #fujifilm #fujixt1

It’s Friday…which seems like a great excuse to take a look at some awesome images from space.
First, let’s start with our home planet: Earth.
This view of the entire sunlit side of Earth was taken from one million miles away…yes, one MILLION! Our EPIC camera on the Deep Space Climate Observatory captured this image in July 2015 and the picture was generated by combining three separate images to create a photographic-quality image.
Next, let’s venture out 4,000 light-years from Earth.
This image, taken by the Hubble Space Telescope, is not only stunning…but shows the colorful “last hurrah” of a star like our sun. This star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star’s remaining core. Our sun will eventually burn out and shroud itself with stellar debris…but not for another 5 billion years.
The material expelled by the star glows with different colors depending on its composition, its density and how close it is to the hot central star. Blue samples helium; blue-green oxygen, and red nitrogen and hydrogen.
Want to see some rocks on Mars?
Here’s an image of the layered geologic past of Mars revealed in stunning detail. This color image was returned by our Curiosity Mars rover, which is currently “roving” around the Red Planet, exploring the “Murray Buttes” region.
In this region, Curiosity is investigating how and when the habitable ancient conditions known from the mission’s earlier findings evolved into conditions drier and less favorable for life.
Did you know there are people currently living and working in space?
Right now, three people from three different countries are living and working 250 miles above Earth on the International Space Station. While there, they are performing important experiments that will help us back here on Earth, and with future exploration to deep space.
This image, taken by NASA astronaut Kate Rubins shows the stunning moonrise over Earth from the perspective of the space station.
Lastly, let’s venture over to someplace REALLY hot…our sun.
The sun is the center of our solar system, and makes up 99.8% of the mass of the entire solar system…so it’s pretty huge. Since the sun is a star, it does not have a solid surface, but is a ball of gas held together by its own gravity. The temperature at the sun’s core is about 27 million degrees Fahrenheit (15 million degrees Celsius)…so HOT!
This awesome visualization appears to show the sun spinning, as if stuck on a pinwheel. It is actually the spacecraft, SDO, that did the spinning though. Engineers instructed our Solar Dynamics Observatory (SDO) to roll 360 degrees on one axis, during this seven-hour maneuver, the spacecraft took an image every 12 seconds.
This maneuver happens twice a year to help SDO’s imager instrument to take precise measurements of the solar limb (the outer edge of the sun as seen by SDO).
Thanks for spacing out with us…you may now resume your Friday.

If men stopped working…the world would continue on.
If women stopped working, then things would get ugly.
Artist and graphic designer Mike Okuda may not be a household name, but you’re more familiar with his work than you know. Okuda’s artistic vision has left a mark here at NASA and on Star Trek. The series debuted 50 years ago in September 1966 and the distinctive lines and shapes of logos and ships that he created have etched their way into the minds of fans and inspired many.
Flight Ops
The Flight Operations patch has a lengthy history, the original version of which dates to the early 1970s. Having designed a version of the patch, Okuda had some insights about the evolution of the design.
“The original version of that emblem was designed around 1972 by Robert McCall and represented Mission Control. It later changed to Mission Operations. I did the 2004 version, incorporating the space station, and reflecting the long-term goals of returning to the Moon, then on to Mars and beyond. I later did a version intended to reflect the new generation of spacecraft that are succeeding the shuttle, and most recently the 2014 version reflecting the merger of Mission Operations with the Astronaut Office under the new banner Flight Operations.”
“The NASA logos and patches are an important part of NASA culture,” Okuda said. “They create a team identity and they focus pride on a mission.”
In July 2009, Okuda received the NASA Exceptional Public Service Medal, which is awarded to those who are not government employees, but have made exceptional contributions to NASA’s mission. Above, Okuda holds one of the mission patches he designed, this one for STS-125, the final servicing mission to the Hubble Space Telescope.
Orion
Among the other patches that Okuda has designed for us, it one for the Orion crew exploration vehicle. Orion is an integral of our Journey to Mars and is an advanced spacecraft that will take our astronauts deeper into the solar system than ever before.
Okuda’s vision of space can be seen in the Star Trek series through his futuristic set designs, a vision that came from his childhood fascination with the space program.

So, what I'm getting is metric vs. imperial is a states' right issue
The United States, much to my own surprise, does use the metric system. But only at the Federal level. The Drug Enforcement Administration seizes kilos of cocaine. Soldiers determine distance by “klicks” or kilometers. The Federal Government of the United States officially works in metric. Adoption of the metric system over the imperial system was left up to the individual state governments, who chose freedom (and not having to pay to re-survey all their land).
Some guy just mansplained space to an actual fucking astronaut.
Proportional risk
I've begun to develop a strong fear of the weather. Lightning and wind also terrify me. When someone is afraid of flying, there are statistics which could help them understand how little a risk they are actually taking. With this statistic method in mind, is there anything I could remind myself of when I begin to become frightened, that could help relax me a bit? Thank you :)
The National Safety Council organized a handy chart of “What are the Odds of Dying From” that has some handy statistics. There’s a lot more things that we are significantly more at risk for statistically than lightning. For instance you have a 1 in 672 chance of dying as a pedestrian in your life while a 1 in 174,426 chance of dying from lightning. Yet we don’t carry the same fear when walking as we do for lightning.
Something to consider here, we’re much more often “exposed” to being pedestrians than we are exposed to lightning, so this makes a bit of sense that the numbers are so skewed, but the point of fear still stands.
Lightning is serious business, but as I said earlier we need to approach lightning intelligently.
If you look at the an analysis of lightning deaths in the US about two thirds of incidents occurred to people engaged in outdoor activities. So basically people that are outside enjoying the day when a storm comes along, and they decide to either watch the storm from an unsafe place, or keep going with the activity. Going further into outdoor “leisure” activities, of that two thirds about 35% of those activities were water related (largely fishing, but hey, why not looks at the study yourself!).
Worth mentioning, the study also pointed out that 79% of victims were male - being okay with risky behaviours doesn’t make you cool and tough, it makes you an idiot. As the study put it:
Possible explanationsfor this finding are that males are unaware of all the dangers associated with lightning, are more likely tobe in vulnerable situations, are unwilling to be inconvenienced by the threat of lightning, are in situationsthat make it difficult to get to a safe place in a timely manner, don’t react quickly to the lightning threat, orany combination of these explanations. In short, because of their behavior, males are at a higher risk ofbeing struck and, consequently, are struck and killed by lightning more often than females.
Here’s a breakdown of activities people are doing when they die from a lightning strike:
Notice these are all things that are outside! The study stated that things that contributed to lightning fatalities were people’s unwillingness to postpone activities, not being aware of approaching storms (you’re either weatherwise, or otherwise!), being in a vulnerable location, an inability or unwillingness to get to a safe place.
So how do we be safe during a thunderstorm? Do as the NOAA says “when thunder roars, go indoors”! If you know there are going to be storms that day stay alert and take a glance at a radar map every now and then (lord knows you probably have a smart phone), and have an idea of where you’ll go when a storm is near. If you’re unable to get indoors avoid hilltops, isolated tall objects like poles or trees, spread out if you’re in a group, and try to avoid wet items and areas - these won’t make you safe, but will slightly decrease your risk. The only completely safe action is getting inside a building or vehicle.
Have a look over this page on lightning safety and these tips for more info.
So bottom line, should you have a healthy respect for lightning? Yes. Should you be terrified of lightning? No. Be smart and follow the safety tips, you’ll be alright.
Thanks for reading, and I hope this helped!
