“A major new window...”

I enjoyed reading the article "A major new window on physics” (Zoroastrians Abroad, Parsiana, April 2005) regarding Dr Rusi Taleyarkhan’s experiment with fusion energy.

Accuracy in a published work is always necessary and it is even more so when reporting scientific matter. In the sidepiece titled ‘Why seawater?’ there is an error in the second paragraph which I would like to point out. While a heavy hydrogen nucleus does contain one proton and one neutron, the normal hydrogen nucleus contains only one proton, not one neutron as mentioned in your article.
