Starting from Scratch

I have a little poster in my home office that says:

“To make an apple pie from scratch you must first create the universe” – Carl Sagan

So when I saw the title of this TED Talk I couldn’t resist it and spent about 15 minutes completely enthralled…….

It is titled “How I built a toaster from scratch”…. You can watch it here:
