Upcoming International Online Maths Camp on 15th and 29th June 2024

The next International Online Maths Camp between Germany and USA will take place on 15th and 29th June 2024.

Please register online via the link below.

The local times will be 9am US Central Time, which is 4pm German time. There will be one session of about 2 hours on each of the dates. The first session (15th June) will be led by Dr. PJ Couch (Lamar University), the topic is "Mad Vet World".  The meeting tool will be Webex. It is best (but not necessary) to install the Webex App in advance.

Upcoming International Online Maths Camp on November 10/11 for Australia and USA

The next International online Maths Camp will be led by Dr. Braxton Carrigan (Southern Connecticut State University) on November 10/11. The topic will be Skolem labelings, abstract below. Because of the time zones this session is mainly thought for students from Australia and the US, but anyone from Europe who is keen enough to get up late at night for some interesting maths is welcome! Here are the local times: 

US Eastern Time Friday, November 10, 5:30 pm - 8:30 pm
US Central Time (Alabama, Texas) Friday, November 10, 4:30 pm - 7:30 pm
AEST (Sydney, Canberra) Saturday, November 11, 9:30 am
EST (Brisbane) Saturday, November 11, 8:30 am
Darwin Saturday, November 11, 8:00 am
Germany Friday, November 10, 23:30
Wales Friday, November 10, 22:30

Abstract: Skolem World will explore the ideas of positive integer labeling in two settings, according to rules that will be defined by distance. We will begin with exploring some examples of integer sequences and progress by abstracting our process to labeling graphs. None of the structures we explore require any previous knowledge or work in these areas. The problems are visual and accessible. The World leaders are both located in the U.S.A. Dr. PJ Couch is a research mathematician in Texas and Dr. Braxton Carrigan is a research mathematician in Connecticut. The World will end with a chance to explore some related open problems.

International Online Maths Camp on 14th and 28th October 2023

The next International Online Maths Camp will start very soon! Please register below to get the meeting link. The dates and times are:

Saturday, 14th October 2023:  Saturday, 28th October 2023: 

Wales: 8:00 am -- 11:00 am

Germany: 9:00 am -- 12:00 am

Darwin: 4:30 pm -- 7:30 pm

Canberra: 6:00 pm -- 9:00 pm

Wales: 8:00 am -- 11:00 am

Germany: 9:00 am -- 12:00 am

Darwin: 4:30 pm -- 7:30 pm

Canberra: 6:00 pm -- 9:00 pm

Abstract for October 28: Marginal Analysis World on Saturday October 28th has two parts, to allow us to explore one maths topic in more depth, and to see the many different ways that it can be considered. No preparation is required but we will refer to Pascal's Triangle (and triangular numbers, and the `hockey stick') and Catalan numbers). Some notes on these will be provided for easy reference. Pascal's triangle is related to binomials. Binomials, functions and calculus will be referred to but you do not need to have prior knowledge of them. If you have studied these topics then some of the ideas considered in the World will be more meaningful. The World leaders are both Australian.  Dr Ian Roberts is a research mathematician and Elizabeth Barker is a year 12 student and a prior participant at IoMC events. If there is interest, then we might run some shorter but regular sessions on this particular topic.

To the participants of Marginal Analysis World October 28 2023: The World has 2 parts. Part 1 should be understandable by everyone. Part 2 offers a chance to choose your level of difficulty. You might like to have pencil and paper handy so you can play with ideas. There are two files that it is suggested to download to have open and available at the World. You do not need to do this but it will be helpful if you do have it available. It is OK to look at the files before the World but it is not necessary to read or understand them before the World. The first file has problems to consider in Part 2 of the world. The second file is useful reference material and notes. This material is useful at the world,  but also as a guide to interesting maths things to know, learn or explore in the future on the web. The language used is a mix from different levels of maths and anything that is unknown will be explained as requested or required. The World is meant to be fun, informative, but challenging, with options on how much challenge you choose to undertake.
