Working after graduation Reference letter for a student applying for Applied Physics Master programme An example of the reference recommendation letter for a student, applying for a grant of the Master's programme in Applied Physics. I have known Ms. Ann Johnson for the past three semesters as she has taken the following courses which I teach:
What Is a Field? What Are Instants and Durations? A duration is a measure of elapsed time. It is a number with temporal units such as years or seconds. The second is the agreed upon standard unit for the measurement of duration [in the S. In informal conversation, an instant is a very short duration.
In physics, however, an instant is even shorter. It is instantaneous; it has zero duration. There is another sense of the word "instant" which means, not duration, but a time, as when we say it happened at that instant.
Midnight could be such an instant. It is assumed in physics that an event is always a linear continuum of the instants or times or moments that compose the event, but it is an interesting philosophical question to ask how physicists know it is a continuum.
Nobody could ever measure time that finely, even indirectly. A brief comment on the terms: Regarding time, there is no standard terminology about whether to say interval of time or period of time, although the latter is more popular.
The measure of a period of time is called a "duration" and it always needs a Physics motivation letter. The term "interval" in the phrase " spacetime interval " is a different kind of interval.
What Is an Event? In ordinary discourse, an event is a happening lasting a finite duration during which some object changes its properties. So, two events are the same if they are both events of the same object having the same property at the same time.
A possible-worlds analysis of events might be the way to solve this problem of change. Physicists, instead, adopt the idealization that a basic event is a point event: No objects need to be involved.
The point event is specified relative to a reference frame. A physicist's event might be that an electron is there at that point in space at that point in time. A point event might involve multiple properties, such as the value not only of the electromagnetic field but also the mass.
Your trip to the supermarket to buy carrots is, in principle, analyzable as a collection of a great many point events. The point event is ontologically fundamental in the sense that an object is just a process which is composed of a, usually continuous, series of events.
A mathematical space is a collection of points, and the points need not represent real, physical space. Depending on the mathematical space, a point might represent anything, for example, an ordered-pair consisting of an item's sales price in dollars, and a salesperson's name.
These points would compose a two-dimensional space, but the points of a real space, that is, a physical space, can only be spatial locations, that is, places. For other philosophers it is unacceptable because it involves infinity, namely an infinitesimal size.
Inin order to avoid point events altogether, Bertrand Russell and A. Whitehead developed a theory of time based on the assumption that all events in spacetime have a finite, non-zero duration. They believed this defintion of event is closer to our common sense, our informal beliefs about events.
McTaggart argued early in the twentieth century that events change. Many other philosophers those of the so-called B-camp believe it is improper to consider an event to be something that can change, and that the error is in not using the word "change" properly.
This is still an open question in philosophy, but physicists generally use the term "event" as the B-theorists do, namely as something that does not change. For a more detailed discussion of what an event is, see the article on Events. What Is a Reference Frame?
A reference frame for a space [whether it is a physical space, a space-time, or a twelve-dimensional abstract mathematical space] is a standard point of view or a perspective that is usually intended to be usable for making quantitative measurements and judgments about places in the space and the phenomena that take place there.
To be suited for these purposes, a reference frame needs to be specified by or augmented by—the experts are ambiguous about this choosing a coordinate system and specifying its origin and orientation in the space.In later medieval thought the earth was a disk - flat and round - so it was theoretically possible to find the edge of the world and break through to the first heaven.

Dear Sir/Madam With this letter, I would like to express my interest in applying to IPC at the Osaka University as a PH.D student, announced for academic year In high school I graduated with Mathematics, Physics as my majors.5/5(3).
A Physics Teacher instructs students at the high school level on various topics related to matter, force and energy. Some of their primary duties include designing and teaching lessons, assigning homework, grading tests, supervising lab work, and monitoring student progress. Time.
Time is what a clock is used to measure. Information about time tells the durations of events, and when they occur, and which events happen before which others, so time has a very significant role in the universe's organization.
