We are getting reports of a knife attack at a vocational school in Ostrołęka, Poland, which left at least seven people injured, including two seriously, as reported by Poland’s RMF FM radio.

“Henri Kagan discovered a new way of manipulating chemical reactions, allowing a greater excess of one of the mirror images to be created than was previously assumed possible. His discovery has been revolutionary for chemists who develop reactions for the manufacture of pharmaceuticals, flavours, scents and new materials.

Kenso Soai designed the first chemical reaction in which only one of the potential mirror images was formed. Other than life itself, no one had ever achieved this feat. The Soai reaction is one of the most spectacular chemical experiments ever conducted.”
