A card puzzle ; something to apply your physics knowldege

Node id: 2398page

A bit of histroy first: A card puzzle was originally posed by a fellow traveller to me during  train journey from Bombay to Allahabad some time in during my TIFR days (1975-78)


This page links to a

Video of a card puzzle.



Click for Hint

The puzzle can be solved by using concept from Physics called Time Reversal.  In fact any complex variation of this puzzle can be solved.

Alternatively, this video can be used as an example to illustrate the concept of  Time Reversal

A list of complete reference to sources of questions and problems

Node id: 2888page

This page gives an incomplete, but growing list of sources from which many problems have been compiled. Many questions and problems are obvious variations of the original one, an effort is made to list corresponding sources also. Needless to say that this task will never achieve a complete list, neverthelss it has been taken to give the credit where it is due.

The users are welcome to leave comments with  regard to source on the appropriate problem page.

A Mixed Bag of Resources

Node id: 3395page

This section of Warehouse contains a wide variety of resources such as:
Short Examples;
Short Questions:
Recall and Understanding  Questions;
Comprehension Check Ups
and many more, which do not fit into any other repository.
These resources are meant to be mostly used as building blocks of other resources in Proofs.
Each resource belongs to a definite topic of a definite area.

This part of the tree hierarchy is the same as that used for all other repositories.

A Sample Path

Node id: 1509path

This is a path page with a path diagram.

The path page has an embedded tool - path diagram editor, which has its separate toolbar (maybe hidden - look for » button, above the path diagram on the left).

A path page may have additional text below the path diagram.

A Sample Video Page: Newton's Laws of Motion

Node id: 4526video_page

A video page allows one to create a playlist of only Youtube videos. This example uses only 3 videos, but several time-segments (chunks) of these 3 videos are added in the playlist.

The video chunks added in a playlist can be ordered in any desirable way.

When you put a start and end time for a video segment, it plays only for that duration automatically

You may put your notes for

A Time Line of Quantum Mechanics

Node id: 4893curated_content

This article gives time line of quantum mechanics in a brief and concise manner from 1879 to 1995.


"There are some really great articles on the Internet that are informative to a great extent on the timeline of Quantum Mechanics. This is one of the good ones that I found, covering the evolution of Quantum Mechanics from 1897 to 1995 in a concise manner."
(Post by Shobhit Sharma in :  Graduate student in Physics at Duke University.)

I have selection of links to time line articles  The first one is a detailed, yet concise, time line.
