These are just off the top of my head, so don't be bashful about commenting. Let me know which (if any) of these grab you:
“Mama Joules is a place for sharing ideas, because science should be fun.”
"A place to share ideas for making science fun."
“Teaching science, one atom at a time.”
"Give a man fission and he'll have a meltdown in a day. Teach a man fission and he'll have power for life." (OK, so I got a little carried with that one ... )
“Because science should be fun.”
"Sharing science, exploring ideas."
“Sharing ideas, exploring science.”
"Sprinkle some science into your day."
Thanks in advance for your input and have a great week-end! :)
