We had a conversation about words lost in translation, or rather about understanding the meaning of the word in the first place. Barycentre. I look up its translation into Chinese since this is where the conversation started and then back again into English. I’ve been reading Encounters with Plants, Stars and Animals - Things That Are by Amy Leach, and I find a chapter on orbiting objects. 
The Earth is heavy and blue. The Moon circles the Earth. The Earth circles the sun, and both orbit around a point inside of the Earth (which is not the centre of the Earth) - the barycentre. 

I'm making new work, small birds in a bowl, more tumble than flight, with all the words it has gathered. With which to build a nest.
