INTRO (4 Units): Some of the Units may contain unknown facts that are useful. The squares above link to different Units.   Unit 001 It is easier to remember something we see than to remember something we hear. It is easier to remember something we both see and hear than to remember something we only see or hear. Because of the memory dynamics mentioned above, some of these video clips will be easier to remember in the distant future.     001A > 10 seconds from 01:00 to 01:10     001B > 10 seconds from 01:11 to 01:21     001C > 10 seconds from 11:12 to 11:22     001D > 10 seconds from 00:15 to 00:25     Unit 002 It is legal to break the law if you use the "Defence of Necessity" and prove 3 things: 1) There was an imminent peril or danger.  2) There was no reasonable, legal alternative to the illegal course of action you took.  3) The harm (if any) you inflicted was proportional to the harm you avoided.     Unit 003 R. v. Morris (1994): A driver charged with speeding was in the left lane when a speeding vehicle approached her from behind. She used the "Defense of Necessity" to justify why she exceeded the speed limit to pass the vehicles on her right so she could change lanes and get out of the way of the vehicle behind her.     Unit 004 Hundreds of people were shown these logos for the 4-reds URL below the logos. Each person was asked to pick the logo they preferred — about 90% of the respondents preferred the same logo. Each person was also asked if they could remember the 4-reds URL until the year 2040 — only a few said they could.
