What is the most astounding fact you can share with us about the Universe?
Neil deGrasse Tyson, PhD: The most astounding fact… is the knowledge that the atoms that comprise life on Earth, the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy. Guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself. These ingredients become part of gas cloud that condense, collapse, form the next generation of solar systems… stars with orbiting planets, and those planets now have the ingredients for life itself.
So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us.
When I reflect on that fact, I look up – many people feel small because they’re small and the universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant, you want to feel like a participant in the goings-on of activities and events around you. That’s precisely what we are, just by being alive…

Key elements of the turbo-encabulator include unilateral phase detractors and the effects of magneto reluctance and capacitive voractance.
I never thought I’d post myself in a picture so relevant to the main interest of this tumblr page. I programmed the microcontroller and built part of the electronic subsystem for a project going onto the ISS involving immiscible liquid in zero-G. The launch is May 1st on Orbital 2. Cross your fingers!
Homemade taser using an astable oscillator (555 timer circuit), step up transformer, and a couple of voltage multipliers. Runs on a 9V battery. With a bit of tweaking on the cap sizes and a higher ratio transformer, it’ll be able to put out +30,000 V.
I find it helpful at times like these to remind myself that our true enemy is Instinct.
Instinct was our mother when we were an infant species.
Instinct coddled us and kept us safe in those hardscrabble years when we hardened our sticks and cooked our first meals above a meager fire
and started at the shadows that leapt upon the cavern’s walls.
But inseparable from Instinct is its dark twin, Superstition.
Instinct is inextricably bound to unreasoning impulses, and today we clearly see its true nature. Instinct has just become aware of its irrelevance, and like a cornered beast, it will not go down without a bloody fight.
Instinct would inflict a fatal injury on our species.
Instinct creates its own oppressors, and bids us rise up against them.
Instinct tells us that the unknown is a threat, rather than an opportunity.
Instinct slyly and covertly compels us away from change and progress.
Instinct, therefore, must be expunged.
