Detection of Black Holes01:10

Detection of Black Holes

2.6K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Schwarzschild Radius and Event Horizon

2.9K
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

Gravitation Between Spherically Symmetric Masses

1.4K
The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.

Space-Time Curvature and the General Theory of Relativity

4.8K
In 1905, Albert Einstein published his special theory of relativity. According to this theory, no matter in the universe can attain a speed greater than the speed of light in a vacuum, which thus serves as the speed limit of the universe.
This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of...

Radiation: Applications

1.9K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Reduced Mass Coordinates: Isolated Two-body Problem

2.5K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Investigating Black ASL: A Systematic Review.

Andrea Toliver-Smith, Betholyn Gentry

    American Annals of the Deaf

    Summary

    Linguistic variations exist in American Sign Language (ASL), influenced by region, culture, and spoken languages like African American English impacting Black ASL. Empirical research on Black ASL is limited, indicating a nascent field requiring further study.

    Area of Science:

    • Linguistics
    • Sociolinguistics
    • Sign Language Studies

    Background:

    • American Sign Language (ASL) exhibits linguistic variations influenced by regional and cultural factors.
    • Spoken language features can impact sign languages, as seen with African American English influencing Black ASL.
    • The existence and empirical study of Black ASL warrant investigation.

    Purpose of the Study:

    • To conduct a literature review on Black ASL.
    • To identify and document empirical studies concerning Black ASL.
    • To assess the current state of research on linguistic variations in ASL.

    Main Methods:

    • A systematic literature review was performed.
    • Articles were selected based on publication dates (1970-2012), scholarly journal publication, inclusion of a hypothesis, and description of participants and research design.

  • Seven articles met the inclusion criteria.

    • Main Results:

    • All seven reviewed articles identified differences between Black ASL and mainstream ASL.
    • The review uncovered a limited number of empirical research articles on the topic.
    • This indicates that empirical research on ASL linguistic variation is in its early stages.

    Conclusions:

    • Empirical research on linguistic variation in American Sign Language, particularly Black ASL, is significantly underdeveloped.
    • Further research is crucial to fully understand the nuances and extent of linguistic diversity within ASL.
    • The findings highlight the need for continued exploration and documentation of ASL variations.
