The Practice Effect

Physicist Dennis Nuel's career has taken a sudden and startling turn. After being denied access to the Zievatron Project through the political machinations of his chief rival, the self-righteous, priggish Bernard Brady, Dennis is need back - badly. The zievatron, a device created to provide access to parallel worlds, has indeed made contact. But now the return mechanism is malfunctioning, and the only way to repair it is for someone to go through to this alien world where no human has yet ventured. That someone is to be Dennis Nuel.
