Korotkoff Sounds01:12

Korotkoff Sounds

12.7K
Korotkoff sounds are the specific sounds heard while measuring blood pressure using a sphygmomanometer, typically with a stethoscope or a Doppler device. They are named after Russian physician Nikolai Korotkov, who first described them in 1905. These sounds correspond to turbulent blood flow in the artery as the blood pressure cuff is gradually released after inflation.
During blood pressure assessment, inflating the cuff 30 millimeters of mercury above the patient's systolic blood pressure...

Heart Sounds01:15

Heart Sounds

4.3K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Tidal Forces

3.6K
The origin of Earth's ocean tides has been a subject of continuous investigation for over 2000 years. However, the work of Newton is considered to be the beginning of the proper understanding of the phenomenon. Ocean tides are the result of gravitational tidal forces. These same tidal forces are present in any astronomical body; they are responsible for the internal heat that creates the volcanic activity on Io, one of Jupiter's moons, and the breakup of stars that get too close to...

Sound Waves: Resonance01:14

Sound Waves: Resonance

3.7K
Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...

The Auditory Ossicles01:11

The Auditory Ossicles

3.7K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Sound Waves: Interference00:53

Sound Waves: Interference

5.1K
Sound waves can be modeled either as longitudinal waves, wherein the molecules of the medium oscillate around an equilibrium position, or as pressure waves. When two identical waves from the same source superimpose on each other, the combination of two crests or two troughs results in amplitude reinforcement known as constructive interference. If two identical waves, that are initially in phase, become out of phase because of different path lengths, the combination of crests with troughs...

    Summary
    This summary is machine-generated.

    Bounded rationality, originating in economics, focuses on efficient, parsimonious means, minimizing deliberation. Its application to the history of science offers future insights but may be less applicable to past scientific endeavors.

    Area of Science:

    • Economics
    • History of Science
    • Cognitive Science

    Background:

    • The concept of bounded rationality, originating in economics, emphasizes efficient means over optimal solutions.
    • It acknowledges and imposes cognitive limitations through various restrictions, minimizing deliberation.

    Purpose of the Study:

    • To analyze the concept of bounded rationality and its implications.
    • To explore the utility of bounded rationality as a model for the history of science.

    Main Methods:

    • Conceptual analysis of bounded rationality.
    • Examination of its application to scientific practices and history.

    Main Results:

    • Bounded rationality prioritizes efficiency and parsimony, often limiting deliberation.
    • The concept has potential for studying the history of science, particularly future trends.

    Conclusions:

    • Bounded rationality's core principles are efficiency, parsimony, and reduced deliberation.
    • Its utility as a historical model for science may be more pronounced for future scientific developments than past ones.
