CLINAMEN! I now know the name of Lucretius's Atom Quote in Manuel De Landa's Book!

I've always wondered the term for one of my favorite quotes by Lucretius that describes the process of atoms randomly swerving and therefore colliding into each other.  Without these collisions - nothing material could ever be possible.

When atoms are traveling straight down through empty space by their own weight, at quite in determinate times and places, they swerve every so little from their course, just so much that you would call it a change of direction.  It it were not for this swerve, everything would fall downwards through the abyss of space.  No collision would take place and no impact of atom on atom would be created. Thus nature would never have created anything.  -Lucretius 99bc-55bc

So as I was reading up on Dialectical Materialism - and one section wrote about Marx's connection to Epicurus who was connected to Lucretiu's concept of "clinamen" - and I was just so excited to see a name I recognized - so I clicked on Clinamen and it described this quote exactly!  I first found this quote in Manuel De Landa's One Thousand Years of Non-Linear History
