  2. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    Dual I/O commands send the command in single mode, then send the address and return data in dual mode. Quad SPI. Quad SPI (QSPI; different to but has same abbreviation as Queued-SPI described in § Intelligent SPI controllers) goes beyond dual SPI, adding two more I/O lines (SIO2 and SIO3) and sends 4 data bits per clock cycle. Again, it is ...

  3. Runge–Kutta methods - Wikipedia

    en.wikipedia.org/wiki/Runge–Kutta_methods

    In numerical analysis, the Runge–Kutta methods (English: / ˈ r ʊ ŋ ə ˈ k ʊ t ɑː / ⓘ RUUNG-ə-KUUT-tah) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations.

  4. Block cipher mode of operation - Wikipedia

    en.wikipedia.org/wiki/Block_cipher_mode_of_operation

    I.e. 1-bit loss in a 128-bit-wide block cipher like AES will render 129 invalid bits before emitting valid bits. CFB may also self synchronize in some special cases other than those specified. For example, a one bit change in CFB-128 with an underlying 128 bit block cipher, will re-synchronize after two blocks.

  5. Science - Wikipedia

    en.wikipedia.org/wiki/Science

    Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world. Modern science is typically divided into three major branches: the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals ...

  7. Mariana Trench - Wikipedia

    en.wikipedia.org/wiki/Mariana_Trench

    The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.

    en.wikipedia.org/wiki/Black-body_radiation

    Black-body radiation is the thermal electromagnetic radiation within, or surrounding, a body in thermodynamic equilibrium with its environment, emitted by a black body (an idealized opaque, non-reflective body).

    Charles I (19 November 1600 – 30 January 1649) [a] was King of England, Scotland, and Ireland from 27 March 1625 until his execution in 1649. Charles was born into the House of Stuart as the second son of King James VI of Scotland, but after his father inherited the English throne in 1603, he moved to England, where he spent much of the rest ...
