What Is Absolute Zero in Science?
Students adjust their use of spoken, written, and visual language to communicate effectively with a variety of audiences and for different purposes. Alexander and the Terrible, Horrible, No Good, Very Bad Day can be used read-aloud for discussion about how everyone has bad days and how to learn to deal with them. With this lesson, students adjust their use of spoken, written, and visual language to communicate effectively with a variety of audiences and for different purposes.
Students love listening to the story and hearing themselves on their own podcast. Step 1: Have the students write about a time when they had a terrible, horrible, no good, very bad day at school. What happened? Did the day get better? How did it change? Who helped make it better? Step 2: Have the students decide where they would move? Why did they choose that place? Would moving there solve their problem?
Step 3: Have the students illustrate their terrible, horrible, no good, very bad day with a detailed pencil drawing. Use a world map to find Australia and other places students may decide they would move to on their bad day.
On a Mac, use GarageBand to create a podcast. On a PC use Audacity for recording. Each student records a part of their terrible, horrible, no good, very bad day. Have them create a chorus verse that will be said after every few recordings. After the voices are recorded, add a beat or music to the rap. If a computer isn't available, a recording could be made on a smartphone or other recording device.Absolute zero is defined as the point where no more heat can be removed from a system, according to the absolute or thermodynamic temperature scale.
This corresponds to zero Kelvinor minus This is zero on the Rankine scale and minus The classic kinetic theory posits that absolute zero represents the absence of movement of individual molecules.
In other words, while heat may not be removed from a system at absolute zero, absolute zero does not represent the lowest possible enthalpy state. In quantum mechanics, absolute zero represents the lowest internal energy of solid matter in its ground state. Temperature is used to describe how hot or cold an object is. The temperature of an object depends on the speed at which its atoms and molecules oscillate.
Though absolute zero represents oscillations at their slowest speed, their motion never completely stops. It's not possible, thus far, to reach absolute zero—though scientists have approached it.
Massachusetts Institute of Technology researchers set a new record of 0.
Physicists have shown that it is possible to have a negative Kelvin or Rankine temperature. However, this doesn't mean particles are colder than absolute zero; rather, it is an indication that energy has decreased. This is because temperature is a thermodynamic quantity relating energy and entropy. As a system approaches its maximum energy, its energy starts to decrease. This only occurs under special circumstances, as in quasi-equilibrium states in which spin is not in equilibrium with an electromagnetic field.
But such activity can lead to a negative temperature, even though energy is added. Strangely, a system at a negative temperature may be considered hotter than one at a positive temperature.
This is because heat is defined according to the direction in which it flows. Normally, in a positive-temperature world, heat flows from a warmer place such a hot stove to a cooler place such as a room. Heat would flow from a negative system to a positive system. On January 3,scientists formed a quantum gas consisting of potassium atoms that had a negative temperature in terms of motion degrees of freedom. Before this, inWolfgang Ketterle, Patrick Medley, and their team demonstrated the possibility of negative absolute temperature in a magnetic system.
New research into negative temperatures reveals additional mysterious behavior. For example, Achim Rosch, a theoretical physicist at the University of Cologne, in Germany, has calculated that atoms at a negative absolute temperature in a gravitational field might move "up" and not just "down.

Facebook Facebook Twitter Twitter. Updated November 27, We sure do. You can view our parent flyer for this information. However, for practical and aesthetic reasons, you may find it useful to keep the number of students per roster under 35, and the number of rosters per teacher account under On ReadTheory, reading levels are never assigned manually.
All students logging in for the first time will need to take our placement pretest, which starts on a third grade level by default. If that material is too difficult, the pretest will immediately adjust to show first and second grade material instead.
Similarly, if it's too easy, the pretest will progressively move up to grades four, five, and beyond. All students will be moving within a range of levels at all times so that they will be continually challenged.
This provides for maximum differentiation and individualized learning. Our site is fully interactive and responsive, so students will only ever see content based on their previous performance.
On ReadTheory, individual passages are never assigned manually. After our placement pretest, students will be placed at a level, and our program will draw a passage at random from within that level for the student.
Student and teacher accounts are equipped with different functions, and accounts cannot flip back and forth between these functions.Vt commodore price

If the total gains of the participants are added up and the total losses are subtracted, they will sum to zero. Thus, cutting a cakewhere taking a larger piece reduces the amount of cake available for others as much as it increases the amount available for that taker, is a zero-sum game if all participants value each unit of cake equally see marginal utility.
In contrast, non-zero-sum describes a situation in which the interacting parties' aggregate gains and losses can be less than or more than zero.
A zero-sum game is also called a strictly competitive game while non-zero-sum games can be either competitive or non-competitive. Zero-sum games are most often solved with the minimax theorem which is closely related to linear programming duality or with Nash equilibrium. Humans have a cognitive bias towards seeing situations as zero-sum, known as zero-sum bias. The zero-sum property if one gains, another loses means that any result of a zero-sum situation is Pareto optimal.
Generally, any game where all strategies are Pareto optimal is called a conflict game. Zero-sum games are a specific example of constant sum games where the sum of each outcome is always zero. Such games are distributive, not integrative; the pie cannot be enlarged by good negotiation. Situations where participants can all gain or suffer together are referred to as non-zero-sum.
Thus, a country with an excess of bananas trading with another country for their excess of apples, where both benefit from the transaction, is in a non-zero-sum situation. Other non-zero-sum games are games in which the sum of gains and losses by the players are sometimes more or less than what they began with. The idea of Pareto optimal payoff in a zero-sum game gives rise to a generalized relative selfish rationality standard, the punishing-the-opponent standard, where both players always seek to minimize the opponent's payoff at a favorable cost to himself rather to prefer more than less.
The punishing-the-opponent standard can be used in both zero-sum games e. For two-player finite zero-sum games, the different game theoretic solution concepts of Nash equilibriumminimaxand maximin all give the same solution. If the players are allowed to play a mixed strategythe game always has an equilibrium.
A game's payoff matrix is a convenient representation. Consider for example the two-player zero-sum game pictured at right or above. The order of play proceeds as follows: The first player red chooses in secret one of the two actions 1 or 2; the second player blueunaware of the first player's choice, chooses in secret one of the three actions A, B or C.
Then, the choices are revealed and each player's points total is affected according to the payoff for those choices. Example: Red chooses action 2 and Blue chooses action B. When the payoff is allocated, Red gains 20 points and Blue loses 20 points.
In this example game, both players know the payoff matrix and attempt to maximize the number of their points. Red could reason as follows: "With action 2, I could lose up to 20 points and can win only 20, and with action 1 I can lose only 10 but can win up to 30, so action 1 looks a lot better. If both players take these actions, Red will win 20 points.
If Blue anticipates Red's reasoning and choice of action 1, Blue may choose action B, so as to win 10 points.Keep kids learning with daily schedules and activities.

What a day! Alexander wakes up with gum in his hair and trips on his skateboard. His mom forgets to put dessert in his lunch box, and his dentist finds a cavity! Anyone who's ever had a day they'd rather forget will love this cleverly illustrated, laugh-out-loud account of one boy's day of misfortune. Alexander's day may be awful for him, but it is pure enjoyment for 5- to 9-year-olds.
As a bedtime read for any kid who has just had one of those days, this one's a winner--it's almost guaranteed to chase away the blues. When it was read to a group of 5- and 6-year-olds, it was hard to tell who was having more fun, the adult reader or the audience of giggling kids.
The plot, though simple, presents an interesting take on everyday childhood problems. The text is written in a conversational style from the viewpoint of a young boy, so it's by far more entertainment than English lesson. Ray Cruz's black-and-white line drawings lend themselves well to the story's mood.
Cruz has an undeniable knack for realism, and he captures Alexander's emotions wonderfully. Families can talk about bad days.

Who will be eaten first?Written by Pat Rushinthe story centres on Qohen Leth Waltza reclusive computer genius working on a formula to determine whether life holds any meaning. Gilliam has given conflicting statements about whether his personal view is that the film serves as the third part of a satirical dystopian trilogy or " Orwellian triptych" begun with 's Brazil and continued with 's 12 Monkeys.
The film began production in October Qohen Leth, an eccentric programmer who refers to himself in the plural, is assigned to "crunch entities" for a company named Mancom. Finding himself suffering existential angstQohen constantly waits for a phone call, hoping that it might bring him happiness or the answers he seeks.
When Qohen requests a "disability" evaluation, three company doctors determine that he is physically healthy, but require he have therapy from Dr Shrink- ROMan AI therapist designed to provide mental evaluation.
Wanting to meet with "Management", Qohen attends a party held by his supervisor, Joby. Stumbling into an empty room, Qohen finds Management and requests to work from home, as he would be more productive and would no longer risk missing his call; Management simply notes he finds Qohen "quite insane," but later grants his request.
Qohen is pressed into staying at the party by Joby, but chokes on an olive and is rescued by Bainsley, a partygoer. As he begins working from home, Qohen is required to order the data of the Neural Net Mancrive, a massive supercomputer that contains all of the entities crunched by workers, with the goal of solving the "Zero Theorem", a mysterious mathematical formula.
Qohen spends months as a hermit working on the program, during which he is diagnosed with multiple conditions by Shrink-ROM and begins experiencing nightmares involving a black hole.
Frustrated with his work, Qohen smashes his computer with a hammer, and is soon visited by Bainsley. Qohen confides in Bainsley that he believes he accidentally hung up a call that would have given him the meaning of lifeand has desperately been waiting for a call-back ever since.
Qohen is then visited by Bob, the teenage son of Management. Bob repairs his computer, reveals Management is spying on him, and suggests that Bainsley is only interested in Qohen because she is paid to be.
Bob promises to get Qohen his call if he continues working on the Zero Theorem. Having received a VR suit from Bainsley, Qohen interacts with her through virtual reality, which makes them both appear on a beach together.
When Qohen asks if the sun in the horizon ever sets, Bainsley responds it is not programmed to do so. They soon kiss one another. Bob visits Qohen again and tells him that the Zero Theorem aims to prove life is meaningless through the Big Crunch theory.
Digitally connecting to Bainsley again, Qohen is comforted by her, but when he denounces Management and suggests eloping together, she forcefully disconnects, damaging Qohen's suit. When Bob takes his suit to repair it, Qohen connects to Bainsley unannounced, only to discover she is a webcam stripper.
