Some items to ponder today:

What is this giant sphere in the Bosnian forest? Is it nature at work, or an ancient civilization?

What do you think of clouds? And did you know there is drama in the science of clouds? 

How much did Victorian experimentation with psychedelics influence Alice in Wonderland?

And, finally, how amazing would it be to attend Festival 23? If anyone’s near Yorkshire this summer, go and report back!
