## Bogdanov Update

Earlier this year the Bogdanov brothers published Le Visage de Dieu, yet another book dealing with their ideas about the big-bang and pre-big-bang physics. This follows their earlier Avant le Big Bang, and L’équation Bogdanov : Le secret de l’origine … Continue reading

## Bogdanovs Redux

A couple years ago two French brothers, Igor and Grichka Bogdanov, managed to get Ph.Ds in France and publish several nonsensical papers about quantum gravity in refereed physics journals, several of them rather well-known and prestigious ones. John Baez has … Continue reading
