  2. Barometer question - Wikipedia

    en.wikipedia.org/wiki/Barometer_question

    By mutual agreement with the student and the examiner, Calandra gave the student another opportunity to answer, warning the student the answer would require demonstrating some knowledge of physics. The student came up with several possible answers, but settled on dropping the barometer from the top of the building, timing its fall, and using ...

    [4] [5] If used as part of a summative assessment they are usually given a low weight, [6] between 10% and 25% of the total mark of the course for all problem sets put together, [3] [5] and sometimes will count for nothing if the student receives a better grade on the exam. Alternatively, problem sets may be used purely for formative assessment ...

    en.wikipedia.org/wiki/Fermi_problem

    A Fermi problem (or Fermi quiz, Fermi question, Fermi estimate), also known as an order-of-magnitude problem (or order-of-magnitude estimate, order estimation), is an estimation problem in physics or engineering education, designed to teach dimensional analysis or approximation of extreme scientific calculations.

  6. Worked-example effect - Wikipedia

    en.wikipedia.org/wiki/Worked-example_effect

    The worked-example effect is a learning effect predicted by cognitive load theory. [1] [full citation needed] Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving [2] [page needed] and discovery learning.

  7. Rope-burning puzzle - Wikipedia

    en.wikipedia.org/wiki/Rope-burning_puzzle

    A common and simple version of this problem asks to measure a time of 45 seconds using only two fuses that each burn for a minute. The assumptions of the problem are usually specified in a way that prevents measuring out 3/4 of the length of one fuse and burning it end-to-end, for instance by stating that the fuses burn unevenly along their length.

    A comprehensive list of discriminatory acts against American Muslims might be impossible, but The Huffington Post wants to document this deplorable wave of hate using news reports and firsthand accounts.

  9. List of unsolved problems in physics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
