  • How the RESISTORS Put Computing into 1960s Counter-culture December 12, 2025
    In late April of 1968, a computer conference in Atlantic City, N.J., got off to a rocky start. A strike by telephone operators prevented exhibitors from linking their terminals to off-site computers, as union-sympathetic workers refused to wire up the necessary connections. Companies’ displays were effectively dead. This article is an adapted excerpt from W. […]

  • A Chip That Keeps Time (Almost) Like an Atomic Clock December 17, 2025
    For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the basis for the definition of a second. Now, a new challenger has emerged in the timekeeping arena. Researchers recently developed a […]
