Occasionally, in the United States, the Hebrew letters on the dreidel form an English-language mnemonic about the rules: Hay or "H" for "half;" Gimel or "G" for "get all;" Nun or "N" for "nothing;" and Shin or "S" for "share".

Thomas Robinson and Sujith Vijay have shown that the expected number of spins in a game of dreidel is O n 2 , where n is the number of game pieces each player begins with.

The implied constant depends on the number of players. Robert Feinerman has shown that the game of dreidel is "unfair", in that the first player to spin has a better expected outcome than the second player, and the second better than the third, and so on.

Childhood enjoyment of dreidels has led to interest in collecting them in adulthood. Antique dreidels are of increasing value and interest: different styles of dreidels are to be found across the world.

Exemplars include dreidels fashioned in wood, silver, brass and lead. Dreidel is now a spoof competitive sport in North America.

Pamskee was the MLD Champion. In , Good Morning America published a story on Dreidel Renaissance reporting on the rising popularity of the dreidel.

Neue Drudels zum Raten und Lachen. Die Lösungen findest du unterhalb der einzelnen Bildrätsel.

Junge mit einer Baseballkappe und Kopfhörern von oben. German physicist Paul Drude proposed his model in when it was not clear whether atoms existed, and it was not clear what atoms were on a microscopic scale.

Drude starts from the discovery of electrons in by J. Thomson and assumes as a simplistic model of solids that the bulk of the solid is composed of positively charged scattering centers, and a sea of electrons submerge those scattering centers to make the total solid neutral from a charge perspective.

In modern terms this is reflected in the valence electron model where the sea of electrons is composed of the valence electrons only, [6] and not the full set of electrons available in the solid, and the scattering centers are the inner shells of tightly bound electrons to the nucleus.

The scattering centers had a positive charge equivalent to the valence number of the atoms. Whenever people tried to give more substance and detail to the nature of the scattering centers, and the mechanics of scattering, and the meaning of the length of scattering, all these attempts ended in failures.

The scattering lengths computed in the Drude model, are of the order of 10 to inter-atomic distances, and also these could not be given proper microscopic explanations.

In modern terms, there are experiments in which electrons can travel for meters in a solid in the same manner as they would travel in free space, and this shows how a purely classical model cannot work.

Drude scattering is not electron-electron scattering which is only a secondary phenomenon in the modern theory, neither nuclear scattering given electrons can be at most be absorbed by nuclei.

The model remains a bit mute on the microscopic mechanisms, in modern terms this is what is now called the "primary scattering mechanism" where the underlying phenomenon can be different case per case.

The model gives better predictions for metals, especially in regards to conductivity, [note 6] and sometimes is called Drude theory of metals.

This is because metals have essentially a better approximation to the free electron model , i. The same Drude theory, despite inconsistencies which baffled most physicists of the period, was the major one accepted to explain solids until the introduction in of the Drude-Sommerfeld model.

A few more hints of the correct ingredients of a modern theory of solids was given by the following:.

Drude used Maxwell—Boltzmann statistics for the gas of electrons and for deriving the model, which was the only one available at that time.

By replacing the statistics with the correct Fermi Dirac statistics , Sommerfeld significantly improved the predictions of the model, although still having a semi-classical theory that could not predict all results of the modern quantum theory of solids.

Nowadays Drude and Sommerfeld models are still significant to understanding the qualitative behaviour of solids and to get a first qualitative understanding of a specific experimental setup.

It is less common to use a full-blown quantum field theory from first principles, given the complexities due to the huge numbers of particles and interactions and the little added value of the extra mathematics involved considering the incremental gain in numerical precision of the predictions.

Removing or improving upon each of these assumptions gives more refined models, that can more accurately describe different solids:.

During its last collision, this electron will have been just as likely to have bounced forward as backward, so all prior contributions to the electron's momentum may be ignored, resulting in the expression.

The dynamics may also be described by introducing an effective drag force. Lorentz Force on the carrier or more specifically on the electron.
