Left-right, up-down, back-forth: These are the dimensional directions we’re able to notice.

For me actually the fourth dimension still remains something that is quite hard to wrap my head around – haha around – but luckily string theorist Brain Greene comes to the rescue. In this video below he beautifully explains the idea of higher dimensions.
