Maar er is meer, veel meer.</p>\n<p>Voor talloze raadsels in de fysica is in verleden &eacute;n heden een oplossing bedacht in de vorm van een nieuw deeltje. Deeltjes met curieuze namen en eigenschappen: gravitonen, spiegeldeeltjes, extra quarks, magnetische monopolen&nbsp;en steriele neutrino's. D&eacute;ze deeltjes staan centraal in <em>De deeltjessafari</em>.</p>\n<p>Keulen werd alom geprezen om zijn gidskwaliteiten, die ook in wilde wereld van <em>De deeltjessafari </em>hun grote nut bewijzen.</p>\n<p>&nbsp;</p>\n<p><strong>Jean-Paul Keulen</strong> is redacteur van <em>KIJK</em>. Voor dit tijdschrift heeft hij al vele artikelen geschreven over deeltjesfysica.</p>",
