Symmetries & Groups - Professor Raymond Flood
Δημοσιεύτηκε στις 13 Δεκ 2013
One
of the most important patterns that a mathematician looks for is
whether or not an object has symmetries i.e. is left unchanged or
invariant after some operation, for example reflection or rotation. A
square has many symmetries under the operations of rotation and
reflection whereas a rectangle has fewer symmetries. The concept of a
group of symmetries measures and describes how much symmetry an object
has. This concept of a group is one of the most important in mathematics
and also helps to describe and explain the natural world.
The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and...
Gresham
College has been giving free public lectures since 1597. This tradition
continues today with all of our five or so public lectures a week being
made available for free download from our website. There are currently
over 1,500 lectures free to access or download from the website.
