The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

In the United States, the 33rd parallel approximately defines the border between Arkansas and Louisiana.. The 33rd parallel north is a circle of latitude that is 33 degrees north of the Earth's equatorial plane.
Below is a sortable list of countries by number of Internet users as of 2024.Internet users are defined as persons who accessed the Internet in the last 12 months from any device, including mobile phones.
The birth rates [1] and death rates [2] in columns one and two are the CIA World Factbook estimates for the year 2022 unless otherwise noted, rounded to the nearest tenth (except for Mayotte and the Falkland Islands with 2010 and 2012 estimates respectively).
California, New York, and Michigan have the largest MENA populations, and Lebanese, Iranian, and Egyptian populations made up nearly half of them. [44] This was almost triple the 2000 census' estimate of a population of 1.2 million Arab Americans, based on the "Ancestry" question rather than the racial category question. [ 45 ]
