For spin in QM, there is only M_S, which is the spin projection along a chosen axis. This makes "left" and "right" hard to define.Tjen said:I'm attempting to create a quiz with the first 8 answers with the possible answers of any of up, down, left, and right... From doing research, I understand this is possible for quantum mechanic problems in reguards to spin. Is this true? I would like to make a believeable college level simple quiz/test that has these answer possibilities for the first 8 question. Please let me know, thanks.
What about left-handed and right-handed spin-1/2 particles? Possible question: what is the handedness of the (electron) neutrino?Meir Achuz said:For spin in QM, there is only M_S, which is the spin projection along a chosen axis. This makes "left" and "right" hard to define.
By convention, "right-handed" for a particle's spin means that the "helicity" is positive (and v-v for LH). Helicity equals the component of a particle's spin along the direction of its momentum. The reason for this designation is probably that, in classical terminology, positive angular momentum component corresponds to right-handed rotation. Even though there is no rotation in the QM spin of an elementary particle, the notation is still used.koantum said:What about left-handed and right-handed spin-1/2 particles?

Actually I offered these questions only as example questions for Tjen's quizz. Didn't mean to get an answer!Meir Achuz said:By convention, "right-handed" for a particle's spin means ...
"This may seem like a very strange question" is a phrase that is often used to introduce a question or topic that may seem odd or unconventional. It is typically used to acknowledge that the question may not have an obvious or straightforward answer.
There are many reasons why someone might ask a strange question. It could be out of genuine curiosity, to spark a thought-provoking discussion, or to challenge traditional ways of thinking. Asking strange questions can also lead to new discoveries and advancements in science and technology.
Yes, asking strange questions can be extremely valuable in scientific research. It can challenge established theories and lead to new ideas, experiments, and discoveries. It also encourages critical thinking and creativity, which are essential skills in the scientific community.
Asking strange questions can benefit society in many ways. It can lead to breakthroughs in medicine, technology, and other areas of science that can improve our quality of life. It can also help us to think outside the box and find solutions to complex problems that we may not have considered otherwise.
In science, there is no such thing as a "strange" question. All questions are considered valid and important in the pursuit of knowledge and understanding. Asking unconventional or unexpected questions can lead to new discoveries and advancements in science, making it a crucial part of the scientific process.
