    The telescope

    also in Science and technology

    Hans Lippershey filed for a patent on a device that made distant objects look nearer. Turned to the sky by Galileo, the telescope transformed astronomy and our view of the cosmos.

    • This new system began with the first Puritan church at Salem, organized in 1629 by the so-called “Salem Procedure.”

    The pendulum clock

    also in Science and technology

    Christiaan Huygens used a swinging pendulum to regulate a clock, making timekeeping far more accurate. Precise clocks aided science, navigation and daily coordination.

    The seed drill

    also in Science and technology

    Jethro Tull built a machine that planted seeds in neat rows at set depth. It cut waste and raised yields and was an early step toward mechanized farming.

    The telephone

    also in Infrastructure and logistics, Science and technology

    Alexander Graham Bell patented a device that carried the human voice over an electric wire. The telephone let people talk across distances and grew into a worldwide network.

    • It took thirty years to beat down a fierce oppo- sition, but by the 1880s it had come to pass — “they” had the children.

    Penicillin and antibiotics

    also in Infrastructure and logistics, Science and technology

    Alexander Fleming noticed that a mold killed bacteria, leading to penicillin, the first true antibiotic. Antibiotics made once fatal infections curable and transformed medicine.

    • The most impressive statistic in French's study was a correlation coefficient of .82, which expressed the relationship between the composite rating of teaching ability and the measures of group attention during recitation periods.

    The spread of the internet and later the smartphone and social media wires the world into a single real-time network. It becomes the core infrastructure of globalization, commerce, and communication, and, through surveillance and platform power, an instrument of both state and corporate control. Documented as the backbone of the integrated world order; the specific claim that it is a designed tool of a secret one-world government is a separate conspiracy framing.
