Contact Simon Singh

For the first five years, I was able to answer every single
email received, and it has been great to hear from and write
back to listeners, readers and viewers. However, the number of emails is now so high that I am unable to find the time to answer all of them. I am genuinely sorry. I will still read every email, and I will try to answer the majority of them, but I can no longer guarantee that you will get a response. I hope you understand.

You might find that your question can be answered
somewhere within the site, so I would encourage you to
explore the site before emailing me. There are lots of
sub-sections, so have a look at the site map to help track
down the relevant section.

If you can't find what you are looking for within the site, the links page may help. There are dozens of links to useful and interesting websites. For example, a particularly informative cryptography website is the RSA FAQ page .

If all else fails, then please feel free to e-mail me. In particular, it is great to hear from teenagers or children who have read my books, or seen my TV programmes, or who are just curious about science and mathematics. I look forward to hearing from you.

Please note that I have neither the time nor the expertise to crack coded messages and I cannot comment on any new cryptographic systems or methods for cracking RSA or proofs of Fermat's Last Theorem.
