26 July 1999 to 6 August 1999
The hot big bang theory successfully explains the basic properties of our universe, but it does not address what is perhaps the most interesting question, namely how the structures we see in the universe - planets, stars and galaxies - came to be formed.
Over the last two decades, several theories of structure formation have been investigated, and due to advances in observational techniques these theories are being tested to increasing precision. A host of new experiments, including dedicated satellites from ESA and NASA, will map the cosmic microwave sky, giving us an unprecedentedly clear view of the universe at early epochs, and on the largest visible scales. In parallel, there is a rapidly growing set of complementary data including surveys of the large scale galaxy distribution and the velocity field, of galaxies, quasars and Lyman alpha clouds at high redshift, and of the mass distribution from gravitational lensing.
Theories connecting the origin of structure to fundamental high energy physics include variants of the inflation and cosmic defect theories. According to the latest data, the simplest versions of each appear clearly ruled out. Nevertheless modifications of the theories appear viable at present. If one of the simpler modifications turns out to be correct, we shall be able to determine the cosmological parameters with some precision. Conversely, the refutation of current theories will demand new theoretical ideas.
The ASI will consist of ten days of pedagogical lectures including reviews of the current status of the observations and of the leading theories.

Footnote: The organisers are grateful to NATO for providing financial support for this meeting. However we share deep concerns regarding the actions of all sides of the conflict in the former Yugoslavia including those of NATO. We have therefore decided to organise during the ASI a forum for discussion of the events currently taking place in the Balkans, providing an opportunity for the expression of concerns on all sides. The forum will take place at a venue in Cambridge. Its precise form and focus will be fixed in the light of future developments. We plan to invite a balanced set of speakers including concerned scientists as well as government and NATO representatives.

INI is a creative collaborative space which is occupied by up to fifty-five mathematical scientists at any one time (and many more when there is a workshop). Some of them may not have met before and others may not realise the relevance of other research to their own work.
INI is especially important as a forum where early-career researchers meet senior colleagues and form networks that last a lifetime.
Here you can learn about all activities past, present and future, watch live seminars and submit your own proposals for research programmes.
Within this section of the website you should find all the information required to arrange and plan your visit to the Institute. If you have any further questions, or are unable to find the information you require, please get in touch with the relevant staff member or our Reception team via our contact pages.
INI and its programme participants produce a range of publications to communicate information about activities and events, publish research outcomes, and document case studies which are written for a non-technical audience. You will find access to them all in this section.
The Isaac Newton Institute aims to maximise the benefit of its scientific programmes to the UK mathematical science community in a variety of ways.
Whether spreading research opportunities through its network of correspondents, offering summer schools to early career researchers, or hosting public-facing lectures through events such as the Cambridge Festival, there is always a great deal of activity to catch up on.
Find out about all of these endeavours in this section of the site.
There are various ways to keep up-to-date with current events and happenings at the Isaac Newton Institute. As detailed via the menu links within this section, our output covers social media streams, news articles, a regular podcast series, an online newsletter, and more detailed documents produced throughout the year.
“A world famous place for research in the mathematical sciences with a reputation for efficient management and a warm welcome for visitors”
The Isaac Newton Institute is a national and international visitor research institute. It runs research programmes on selected themes in mathematics and the mathematical sciences with applications over a wide range of science and technology. It attracts leading mathematical scientists from the UK and overseas to interact in research over an extended period.
INI has a vital national role, building on many strengths that already exist in UK universities, aiming to generate a new vitality through stimulating and nurturing research throughout the country.During each scientific programme new collaborations are made and ideas and expertise are exchanged and catalysed through lectures, seminars and informal interaction, which the INI building has been designed specifically to encourage.
For INI’s knowledge exchange arm, please see the Newton Gateway to Mathematics.
The Institute depends upon donations, as well as research grants, to support the world class research undertaken by participants in its programmes.
Fundraising activities are supported by a Development Board comprising leading figures in academia, industry and commerce.
Visit this section to learn more about how you could play a part in supporting INI’s groundbreaking research.
In this section you can find contact information, staff lists, maps and details of how to find INI’s main building in Cambridge.
Our administrative staff can help you with any queries regarding a prospective or planned visit. If you would like to discuss a proposed a research programme or other event, our senior management team will be happy to help.
