First off, Happy Birthday to all the birthday people!!

Second, you're almost there Jsese: homeopathy is like storing the energy state of a building in structure form in a bomb and using the bomb to restore the building that's now in demolished form back to structure form.

Turns out you can bomb a building back into a repaired state. Suck it, peace activists!

Third, obviously the answer to Jess's question is homeopathy (see here).

Since Albert gets to post random questions: What do you think humanity's best invention has been? ("Best" is deliberately vague.)

see below

Birthday happy Pete!

so .... Homeopathy is like bombing your neighbors house?

E = mc² and vibration (only after God sent us Stephen Hawking)

Thanks yo all!

Keep it loose. Keep it tight!
