“From our home on earth we look out into the distances and strive to imagine the sort of world into which we are born. Today we have reached far out into space. Our immediate neighborhood we know intimately. But with increasing distance our knowledge fades . . .until at the last dim horizon we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be suppressed.” –Edwin Hubble

Financial Support for the Center and for Participants



Who Supports Us

Called the “most cost effective program of its kind” by a major funding agency, the Aspen Center for Physics takes pride in the fiscal responsibility that has allowed it to grow and prosper since its beginnings in 1961 and first meetings in 1962.

The Aspen Center for Physics' cognizant grant agency is the National Science Foundation. Since 1972, the NSF has generously provided grant monies annually. NSF funds are used to support the physicists' housing costs in Aspen. This allows some physicists to attend who would not otherwise be able to afford participation. NSF support helps encourage under-represented groups, those whose institutions limit travel funds, and junior scientists. The NSF grant also provides a portion of the cost of operating the Center and a portion of the cost of the summer public lecture series.

The Department of Energy has been instrumental in annual funding of the winter conferences by supporting the publication and secretarial needs of a particle and an astrophysics conference each winter. In addition, the DOE has generously provided support for individual conferences.

The Office of Naval Research has also been very responsive to requests for specific support of Center programs.

Several corporations, foundations, laboratories and individuals also donate to the Center for specific programs, building projects, or for our endowment. Their assistance has been invaluable and has made the Center a viable and prospering institution for theoretical physicists to learn, confer and collaborate to increase our knowledge of the world around us.

How We Support Physicists

A portion of these grants and donations are used to help support physicists while they are in Aspen. Each summer, physicists staying in ACP-arranged housing receive a standard weekly stipend applied toward the summer bill. In the winter, support varies from conference to conference. Winter organizers make decisions about allocating their limited funds.

Very limited funds are also available to qualified participants from the Shaham and Trustee Funds. Email us: acp at aspenphys.org for more information. The Block and Ramond funds have no application process and are awarded by committee.

If You Would Like to Donate

We are a non-profit, 501(c)3 corporation. All donations are greatly appreciated and are tax deductible!

You may give a general donation or target your giving:

Annual Fund is an informal endowment designated by the Board of Trustees to further Center programs.
Bicycle Fund supports the fleet of bicycles which are available free to physicists.
Block Award Fund, named in honor of Martin and Beate Block, is a prized award given to one promising junior physicist during each winter conference.
Ramond Family Fund goes to young families to enjoy their time together in Aspen.
Shaham Fund is given to a young Israeli physicist in memory of the late Jacob Shaham.
Tree Fund supports our effort to replace old aspen trees and develop a mixed forest. Originally this fund was used for trees to surround the “Circle of Serenity” creating a calm, outdoor atmosphere in which to contemplate the secrets of the universe.
Trustee Fund is for young physicists and honors late former trustees of the Center.
