1669: "The Rare Blue Moon"

1675: "The Green Children of Woolpit"

Interesting Things with JC #1675: "The Green Children of Woolpit" – Two green-skinned children appear beside the wolf pits in Woolpit speaking an unknown language, refuse nearly every food except broad beans, and as one child dies and the other survives, her account of Saint Martin’s Land makes the case harder to settle.

1674: "Subproject 68 and the Acoustic Masking Trials"

Interesting Things with JC #1674: "Subproject 68 and the Acoustic Masking Trials" – A recorded message keeps playing for up to 20 hours a day while psychiatric patients are isolated from competing stimuli, and the same phrase continues repeating thousands of times as researchers attempt to reshape thought itself.

1673: "There Is No Universal Now"

Interesting Things with JC #1673: "There Is No Universal Now" – A star 100 light-years away is doing something at this moment, but observers moving at different velocities can assign different times to the same distant event. What appears simultaneous to one observer does not appear simultaneous to another, and the universe continues without a single present moment everyone shares.

1672: "Magnetism is a Relativistic Force"

Interesting Things with JC #1672: "Magnetism is a Relativistic Force" – A current-carrying wire stays electrically neutral on a table while a moving charge beside it feels a magnetic force, but in the charge’s own frame the spacing of charges changes and the same force appears electric.

1671: "What Is the L2 Point?"

Interesting Things with JC #1671: "What Is the L2 Point?" – A mathematician identified a location in space in 1772 where gravity keeps spacecraft moving with Earth around the Sun, and nearly 250 years later observatories began traveling there to do some of humanity's most advanced science.
