Peace Corps.
Colorin colorado, este cuento se ha acabado
July 1, 2016
It feels like an impossible task to condense all that I’ve learned and experienced and become in the last three years into one final blog post, especially since I’m sleep deprived and feeling all of the feelings. Maybe in the next days or weeks or months I will attempt this. But in the meantime, I leave you with this poem, which begins to speak to my feelings toward Peace Corps and toward the Dominican Republic.
Children Running Through
by Rumi, Translation by Coleman Barks with John Moyne
I used to be shy. You made me sing.
I used to refuse things at table. Now I shout for more wine.
In somber dignity, I used to sit on my mat and pray.
Now children run through and make faces at me.
Thank you for following my journey!
Why do people treat autism like it’s such a bad thing? It just means the chemical makeup of your brain is different than others. It’s not that bad and you can learn to live with it. I have it, and I’m just like other people. I have feelings, thoughts, fears, ideas, friends, people I love, and many other things. I’m just a bit more awkward. It’s not that bad.
Happy 4th of July!

Saturn’s Moon, Enceladus, Is Our Closest Great Hope For Life Beyond Earth
“Cassini provided scientists with a wealth of data about Enceladus’ surface and the composition of its powerful plumes. This data showed evidence of a deep saltwater ocean with an energy source beneath Enceladus’ surface. The presence of water, warmth, and organic molecules are the necessary requirements for sustaining life as we know it. Water is proven to exist, while the tidal forces from Saturn provide the necessary heat. Based on observations of other bodies in the Solar System, Enceladus likely contains the raw ingredients for life as well. The suspected existence of all three hints at the possible presence of the precursors to amino acids in this vast subsurface ocean. Should we find extraterrestrial life on Enceladus – or in the geyser-like plumes erupting into space – the implications are almost incomprehensible.”
When you think about life beyond Earth, you likely think of it occurring on a somewhat Earth-like planet. A rocky world, with either a past or present liquid ocean atop the surface, seems ideal. But that might not even be where life on Earth originated! Deep beneath the Earth’s surface, geologically active hydrothermal vents currently support diverse colonies of life without any energy from the Sun. Saturn’s icy moon, Enceladus, has a subsurface ocean unlike any other world we’ve yet discovered. The tidal forces of Saturn itself provide the necessary heat, and also create cracks in the Enceladean surface, enabling massive geysers. This subsurface ocean rises hundreds of kilometers high, regularly resurfaces the world with a coat of fresh ice, and even creates the E-ring of Saturn. But most spectacularly, it may house actively living organisms, and could be the next-best world for life, after Earth, in the Solar System today.
Come get the full story on Enceladus, and welcome Starts With A Bang’s newest contributor, the remarkable Jesse Shanahan!
I remember These! I wonder what has ever happened to Them?
NASA’s Cassini_Mission to Saturn will be Retiring soon.
Future_Missions to Saturn will someday follow in its’ footsteps.
Cassini’s Retirement
What were you up to back in 1997? It was an exciting year. Titanic was setting box office records, Dolly the sheep was getting cloned, and the very first Harry Potter book was hitting shelves. It was also the year that a bus-sized NASA spacecraft named Cassini launched. Carrying the ESA Huygens probe, Cassini set off for Saturn to learn all about the lovely ringed planet.
After almost 20 years, Cassini is entering its last phase, building up to the “Grand Finale” that will culminate in September 2017 (if all goes well).

Mixing Salts of Different Metals.
So this is what happens when you mix salts of different metals (Lithium, Strontium, Sodium, Copper, and Potassium) into methanol and then light that sucker.
Pretty colours is what.
Each metal has a different configuration of electrons orbiting in the atom. When the different atoms get energy from the heat, the electrons in the different metals will be excited by a different amount. When they de-excite they release that energy as light. Different metals release different eneriges. Different energies is different colours. The more energy, the violeter the light.
Using different metal salts is also how fireworks do the thing.
See the streetlight yellow in the Sodium (Na)? Well that’s because we use sodium lamps in streetlights
