#atoms

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff. ↗

The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust. ↗

— Neil deGrasse Tyson

Man is born passionate of body, but with an innate though secret tendency to the love of Good in his main-spring of Mind. But God help us all! It is at present a sad jar of atoms. ↗

Nothing exists except atoms and empty space; everything else is opinion. ↗

If we conceive all the changes in the physical world as reducible to the motion of atoms, motions generated by means of the fixed nuclear forces of those atoms, the whole of the world could thus be known by means of the natural sciences. ↗
