A secondary "slave" pendulum turns a ratchet, which triggers an electromagnet slightly less than every 30 seconds. This electromagnet releases a gravity lever onto the escapement above the master pendulum. A fraction of a second later (but exactly every 30 seconds), the motion of the master pendulum releases the gravity lever to fall farther.
In the mid-1960s, to defeat the advantage of the recently introduced computers for the then popular rally racing in the Midwest, competition lag times in a few events were given in centids (1 ⁄ 100 day, 864 seconds, 14.4 minutes), millids (1 ⁄ 1,000 day, 86.4 seconds), and centims (1 ⁄ 100 minute, 0.6 seconds) the latter two looking and ...
Within a few seconds of the collapse process, a substantial fraction of the matter in the white dwarf undergoes nuclear fusion, releasing enough energy (1– 2 × 10 44 J) [85] to unbind the star in a supernova. [86]
Using drug discovery artificial intelligence algorithms, researchers generate 40,000 potential chemical weapon candidates, [208] [209] which may be relevant to timely regulation of chemicals and related products that can be used to manufacture the fraction of viable candidates and either illustrates or proves that such software is dual-use ...

Researchers show that a new type of X-ray detector, based on a thin film of the low-cost semiconductor mineral perovskite, is 100 times more sensitive than a conventional silicon-based device. The technology could reduce unhealthy radiation exposure and improve the resolution and applications of security scanners and research tools. [70] [71 ...
[287] [291] [292] [293] A preprint suggests that cases "where a small fraction of individuals have disproportionately large numbers of partners, can explain the sustained growth of monkeypox cases among the MSM population" (13 June). [294] [295] The MP incubation period is estimated to be 8.5 days on average and up to 21 days (16 June).
For many decades after its inception, American football was widely regarded as a second-tier sport behind baseball which was long-regarded as America's national pastime. As a result, even the elite levels of American football generally lacked both the financial wherewithal to build their own facilities and the political clout to secure significant public funds to construct such venues, and as ...
