The design of flushing handle

From U-M
picture taken from 4th level, Shapiro Library

the handle is coated green to attract attention, lift it up to solve small issues. but the norm is to press the handle down, and 'liquid waste' has higher frequency, so why not pressing down for small issues? Rule No. XX: always keep the toilet clean.

Where is your seat?

From U-M

So people form clusters based on preferences, liking, internal evaluation and evaluation of others. Every "free-sitting" is indeed not so free, we sit near the people most like ourselves, or sit along, if you think you are 'unique' in quality.

natural clusters undergo phase-transition, transferring from amorphous state into crystal. A human cluster, once formed, starts to exert forces on people trying to leave and repulsion to external people who want to come in.

I get $18
